16: **** Introduction ****
17: TED is a real-time editor written in CLU. It was inspired by the real-time
18: TECO developed at MIT. TED will work with just about any display terminal.
19: (However, TED seems to push terminals harder than Emacs, so you may find that
20: /etc/termcap does not specify enough padding for scrolling or insert/delete
21: line.) Originally written by Russ Atkinson, TED has been extensively modified
22: by Bob Scheifler (RWS) and Eliot Moss (EBM) at MIT-XX, and is currently
23: maintained by Bob Scheifler.
24:
25: To start a TED, just type
26: ted
27: at CSH level. TED will start up, clear the screen, and indicate that you are
28: using the Main buffer. If you want to edit an existing file (or group of
29: files), type
30: ted filespec
31: or
32: ted filespec ... filespec
33: Filespecs can only be given the first time you start up a TED.
34:
35: To get out of TED and back to CSH temporarily, type ^C. To continue TED from
36: CSH, use the FG command. To get out of TED permanently, type ^U0^C.
37:
38: TED is intended to manipulate ASCII text files. Files can be copied to a
39: buffer; the buffer can be changed by commands; and the buffer can be copied
40: back to files, possibly many times.
41:
42: While editing the buffer, a cursor is kept and displayed to indicate the
43: current position in the buffer. Common actions include inserting characters at
44: the cursor, deleting characters at the cursor, and moving the cursor. TED
45: attempts to display a portion of the buffer around the cursor to show the user
46: the text being edited. The displayed portion of the buffer is called the
47: window.
48:
49: Most characters typed are normally self-inserting. That is, as the character
50: is typed it is immediately inserted into the buffer and the display is changed
51: to show the insertion. All control characters (except ^M) are commands that
52: change the current position, change the buffer, or have more complicated
53: effects. For example, control-N (usually written as ^N) causes the cursor to
54: move to the start of the next line. Control characters can be inserted by
55: typing ^Q before typing the control character.
56:
57: Commands that take numeric arguments (the numeric argument is indicated by #)
58: usually have their numeric arguments set by the ^U command. ^U may be followed
59: by a signed number to explicitly specify the argument. If ^U is not followed
60: by a signed number then # becomes the previous # * 4. The default for # is 1.
61: A lone minus sign is equivalent to -1. As the number is typed it will be
62: displayed at the top of the screen. A number is terminated by a non-digit.
63: Most simple commands, and all self-inserting characters, will take a numeric
64: argument. For example, ^U10_ will cause ten underscores to be inserted, and
65: ^U^N will cause the cursor to move down four lines. For some commands, the
66: exact value of the numeric argument is not important, but whether it is greater
67: than one, or less than zero, or some similar condition. For example, ^A will
68: move the cursor to the start, but ^U^A (in fact, any numeric argument greater
69: than one) will move the cursor to the start of the buffer.
70:
71: Some commands require string or file name arguments, and will request them at
72: the bottom of the screen. String arguments and file names are terminated by
73: carriage return, with most control characters having normal editing effects
74: while typing in arguments. To insert a newline into the argument, type a
75: linefeed. A default string or file name is usually supplied, which will be
76: used if no argument is typed. ^R replaces the current argument with the
77: default, ^U^R inserts the default before the cursor, ^U-^R inserts the default
78: after the cursor, ^W replaces the default with the current argument, ^U^W
79: deletes the default, and ^G quits from the command.
80:
81: For file name arguments, the default is used to fill in any missing parts of
82: the file name(s). A file name is considered to consist of four components in
83: the form "dir/name.suffix.other", where the name and suffix parts do not
84: contain periods. The defaults are always used when modifying a file. When
85: reading a file, first all of the defaults are tried, then just the directory
86: default, then all but the directory default, and finally with no defaults.
87: Empty or relative directory fields are completed from the connected directory,
88: which is settable via ^\W. The last string or file name argument is always
89: remembered, and can be inserted at any time via ^VG. For example, if you try
90: to read in a file, but misspell its name, you can save typing the whole name
91: again by typing ^R^VG. Similarly, in the ^Z command, if the replace string is
92: similar to the search string, you can use ^VG in typing the replace string to
93: insert the search string.
94:
95: Some commands require a 1-character option (preceded by an optional numeric
96: argument). Examples of these are ^V, ^X, ^\, ^], and ^_. The optional numeric
97: argument defaults to 1 where applicable, and has an optional minus sign. The
98: actual numeric argument used will be the implicit argument (from a preceding
99: ^U) times any explicit argument given after the option. ^G will quit from the
100: option, ^L will re-display, and ? will type help for the options. The case of
101: the option character does not matter.
102:
103: Some commands require a Yes/No confirmation. A question will be displayed at
104: the top of the screen, to be answered by typing Y or N (case is unimportant).
105: ^G can also be typed to abort the command, so that no action is taken.
106:
107: Long lines are not displayed on multiple lines of the screen. If a line is
108: longer than the width of the screen, TED will display an exclamation mark (!)
109: in the last column to indicate that the line is too long to display completely.
110: ^V! can be used to (find and) display more of a long line.
111:
112: Every so often the buffer is saved to the file "_ted.sav.#" (where # is your
113: process id) in your login directory if the buffer has been changed. This is
114: intended to allow recovery from system crashes. In addition, if TED receives a
115: SIGHUP signal, a save will be performed if the buffer has been changed.
116: However, it is still a good idea to periodically write out your buffer
117: manually. The ^U-^H command can be used to turn saving on or off.
118:
119: Suppose that you want to create a text file from scratch. When TED starts up
120: you have an empty buffer. To insert normal text into the buffer, just type as
121: you would on a typewriter. The delete key (usually represented here as ^?)
122: will allow you to undo minor errors quickly. Then, to save the results of your
123: typing, use the ^W command to write the buffer to a file. For a new file you
124: must give a file name in order to save your work.
125:
126: If you want to edit an old file, use the ^R command to read it into the buffer
127: (the old contents of the buffer will be deleted). To insert (at the cursor)
128: the text of a file into the text of the existing buffer, use the ^U^R command.
129: To find a place that you want to change, you can search for text (using the ^S
130: command) that precedes the place you want changed. Then you can use ^D to
131: delete characters, or ^K to kill entire lines, and insert the correct text.
132: Again, to save the results of your editing, use the ^W command to write the
133: buffer to a file. If you do not give a file name in this case, the ^W command
134: will write out a new version of the file. To append the text of the buffer
135: onto the end of an existing file, use the ^U^W command.
136:
137: The best way to learn TED is to start a TED up and practice manipulating text.
138: Experimenting is encouraged, since you can see the effects of most characters
139: directly on the screen. TED has a built-in help command, ^H, which allows you
140: to view pieces of this file by selecting from a simple menu.

210: **** Short examples ****
211:
212: **** Keypad and function keys ****
213: On VT52's, Heath's, and many other terminals the alternate keypad and function
214: keys can be used. Their corresponding escape sequences can also by typed
215: explicitly. (The keys listed below are for Heath's in shifted keypad mode.)
216:
217: Key: Seq: Meaning:
218:
219: esc esc redefine escape sequence (see below)
220: 7 esc @ move to end of # previous word (^V[)
221: 8,UP esc A move backward # pages (^V^P)
222: 2,DOWN esc B move forward # pages (^V^N)
223: 6,RIGHT esc C move forward # words (^V^F)
224: 4,LEFT esc D move backward # words (^V^B)
225: 5,HOME esc H enter alternate keypad mode
226: ERASE esc J pattern search # times for default (^X^P^M)
227: 1 esc L delete backward to end of # previous word (^V<)
228: 3 esc M delete forward to start of # next word (^V>)
229: 9 esc N move to start of # next word (^V])
230: BLUE esc P delete # words forward (^V^D)
231: RED esc Q delete # words backwards (^V^?)
232: GREY esc R string search forward # times for default (^S^M)
233: f1 esc S string search backward # times for default (^U-^S^M)
234: f2 esc T set case mode for searches (^U0^S)
235: f3 esc U scroll window up # lines (^V-^J)
236: f4 esc V scroll window down # lines (^V^J)
237: f5 esc W reposition window at cursor (^U0^L)
238: esc ? ? print help
239: ENTER esc ? M garbage collect address space (^U^C)
240: . esc ? n exit to CSH (^C)
241: 0 esc ? p search backward # times for default (^U-^S^M)
242: esc ? q delete backward to end of # previous word (^V<)
243: esc ? r move forward # pages (^V^N)
244: esc ? s delete forward to start of # next word (^V>)
245: esc ? t move backward # words (^V^B)
246: shft 5 esc ? u exit alternate keypad mode (when in alternate keypad mode)
247: esc ? v move forward # words (^V^F)
248: esc ? w move to end of # previous word (^V[)
249: esc ? x move backward # pages (^V^P)
250: esc ? y move to start of # next word (^V])
251:
252: The sequences "esc [ char" and "esc O char" are interpreted the same as
253: "esc ? char" when "char" is a lowercase letter, and otherwise are interpreted
254: the same as "esc char".
255:
256: It is also possible to redefine any escape sequence (and hence any function or
257: keypad key), to execute an arbitrary string. The string is executed just like
258: a macro definition, and has basically the same effect as if you typed the
259: characters of the string directly on the keyboard. An escape sequence can be
260: "undefined" back to its original meaning by defining it to the empty string.
261:
262: esc esc char to redefine esc char
263: esc esc ? char to redefine esc ? char
264:
265: Note that a function or keypad key can be redefined by typing ESC and then the
266: function or keypad key.
267:
268: Sequences which are "equivalent" to ^V deletion commands are not completely
269: equivalent, in that they do not save the deleted text in the implicit kill
270: area. If saving is important, these sequences can be redefined to explicitly
271: execute the appropriate ^V command.
272: **** Keypad and function keys ****
273:
274: **** Moving the cursor ****
275: There are many commands for moving the cursor around, almost all of which take
276: a numeric argument as a repetition count:
277:
278: ^U^A moves to the start of the buffer
279: ^U^E moves to the end of the buffer
280: ^A moves to the start of the current line
281: ^B moves to the previous character, wrapping to end of previous line
282: ^E moves to the end of the current line
283: ^F moves to the next character, wrapping to start of next line
284: ^N moves to the start of the next line
285: ^P moves to the start of the previous line
286: ^V^B moves to the start of the previous word
287: ^V^F moves to the end of the next word
288: ^V] moves to the start of the next word
289: ^V[ moves to the end of the previous word
290: ^Vspace skips forward over blanks
291: ^V#L moves to line #
292: ^V^N moves to the next screenful of text
293: ^V^P moves to the previous screenful of text
294: ^V! moves to the next (or current) line which extends off the screen
295: ^X^B^P moves to the previous start of paragraph
296: ^X^E^P moves to the next end of paragraph
297: ^X^F^P moves to the next start of paragraph
298: ^X^B^S moves to the previous start of sentence
299: ^X^E^S moves to the next end of sentence
300: ^X^F^S moves to the next start of sentence
301:
302: Normally, paragraphs are separated by "formatter" lines. Formatter lines are
303: blank lines, and any lines starting with a character in the "no_fill_starters"
304: string variable. This variable contains period and single quote by default,
305: for R20 text formatter command lines. It is also often useful to consider a
306: new paragraph to start at every line with leading spaces or tabs. This can be
307: obtained by setting the "pindent" number variable to a non-zero value (it is
308: zero by default).
309:
310: A sentence is terminated by a period, exclamation point, or question mark,
311: optionally followed by a single quote, double quote, or right "bracket" (round,
312: square, curly, or angle), followed by a newline, a tab, two spaces, a space and
313: a tab, or a space and a newline. Formatter lines also separate sentences.
314:
315: A word consists of letters and digits, plus certain special characters. By
316: default, the only special character is underscore. You can specify what the
317: special characters are by changing the "word_chars" string variable.
318:
319: The following commands move the cursor based on the indentation (amount of
320: leading space consumed by spaces and tabs) of lines in the buffer. These are
321: particularly useful in moving around in (reasonably formatted) CLU and Argus
322: code, but are useful for other languages and documents as well. Most move by
323: comparing the indentation of previous or following lines with the indentation
324: of the current line, and most take a numeric argument as a repetition count:
325:
326: ^X^I^B moves back to the next line with a different indentation
327: ^X^I^D moves to the next line with a greater indentation, provided
328: no line with a lesser indentation intervenes
329: ^X^I^E moves to the next line with a lesser indentation
330: ^X^I^F moves to the next line with a different indentation
331: ^X^I^H moves back to the next line with a greater indentation, provided
332: no line with a lesser indentation intervenes
333: ^X^I^N moves to the next line with the same indentation, provided
334: no line with a lesser indentation intervenes
335: ^X^I^P moves back to the next line with the same indentation, provided
336: no line with a lesser indentation intervenes
337: ^X^I^U moves back to the next line with a lesser indentation
338: ^X^I#^S moves to the next line indented # spaces
339: ^X^I#^^ moves back to the next line indented # spaces
340:
341: The following commands move the cursor based on nested "list" structure, i.e.,
342: based on nested matching ()'s, []'s, {}'s, and <>'s, ignoring the contents of
343: string and character literals. The string variable "list_chars" should be some
344: subset of the characters (), [], {}, <>, ", and ', and defines the active list
345: and literal delimiters, with the default being all but <>.
346:
347: ^X^Z^A moves backward up # list levels
348: ^X^Z^B moves backward over # lists at the current nesting level
349: ^X^Z^D moves (#>0: forward, #<0: backward) down # list levels
350: ^X^Z^E moves forward up # list levels
351: ^X^Z^F moves forward over # lists at the current nesting level
352: ^X^Z^N moves forward up and down (^X^Z^E^X^Z^D) # times
353: ^X^Z^P moves backward up and down (^X^Z^A^X^Z-^D) # times
354: **** Moving the cursor ****
355:
356: **** Moving and deleting text ****
357: The following commands delete text, and take a numeric argument as a repetition
358: count:
359:
360: ^D deletes the next character
361: ^? (DEL) deletes the previous character
362: ^K deletes to the start of the next line
363: ^VK deletes the text between the mark and the cursor
364: ^V^D deletes to the end of the next word
365: ^V^? deletes to the start of the previous word
366: ^V^@ deletes blanks from the cursor forward
367: ^V> deletes to the start of the next word
368: ^V< deletes to the end of the previous word
369:
370: ^D and ^? do not save the deleted text, but the others do. The text deleted by
371: the last such command, or by the last sequence of ^K commands, is retained in
372: an invisible kill area, and can be reinserted anywhere by moving the cursor to
373: the point of insertion and typing ^V^R (to insert after the cursor) or ^V-^R
374: (to insert before the cursor). This is a simple way of moving text.
375:
376: ^V^Z deletes all lines in the buffer.
377:
378: Moving text from one portion of the buffer to another can also be done by
379: copying the text from where it is to an invisible save area using one of the
380: text-saving options of the ^V command, moving the cursor to the point of
381: insertion, and typing ^V^I (to insert after the cursor) or ^V-^I (to insert
382: before the cursor). The text-saving commands are:
383:
384: ^V#C saves the next # words following the cursor
385: ^V#^S saves the next # lines following the cursor
386: ^VS saves the text between the mark and the cursor
387: ^V#^W saves and deletes the next # lines following the cursor
388: ^VW saves and deletes the text between the mark and the cursor
389:
390: The ^T command is used to set an invisible mark in the buffer, which will
391: remain there until a subsequent ^T command moves it, or a ^U^T command
392: exchanges it with the cursor.
393:
394: Note that, as with the kill area, there is only one save area for ^V commands,
395: so that the second time a text-saving command is used the text saved by the
396: first command will no longer be in the save area. The ^V^R and ^V^I commands,
397: however, can be used to insert the same text as many times as desired in as
398: many places as desired.
399:
400: Multiple named save/kill areas can be obtained with multiple buffers commands.
401: **** Moving and deleting text ****
402:
403: **** Searching ****
404: Simple string searching is performed with the ^S command. Searching can be
405: done either forwards or backwards, depending on the numeric argument. For
406: example, ^U5^S will search forward for the fifth occurrence of some string, and
407: ^U-^S will search backwards for the first occurrence. A newline can be
408: included in the search string by typing linefeed. Upper/lower case
409: distinctions normally make a difference when searching, but can be ignored by
410: setting a flag with the ^U0^S command. This flag controls all searching
411: commands, not just ^S.
412:
413: Changing all (or some) occurrences of some string to another string is done by
414: the ^Z command. It will ask for the text string to change, and the string to
415: change it to. Then for each occurrence of the search string you can type Y to
416: change it to the default, or N to avoid changing it, or U to update all
417: remaining occurrences to the default. There are many other options as well.
418: At the end, you can either install the changes or leave the buffer as it was
419: originally.
420:
421: Various options of the ^^ command allow you to peruse or search a list of
422: files. The list is just like that for ^R when making a multi-file buffer. ^^T
423: simply displays the files one at a time, with commands for moving by pages,
424: searching, editing, and moving to the next or previous file. ^^S only displays
425: those files containing a particular string. ^^P only displays those files
426: containing a particular pattern. ^^R reads all of the files into a temporary
427: recursive editing buffer. ^^L simply lists the names of the files, and allows
428: you to select a particular one at a time for editing by placing the cursor on
429: the name of a file and typing ^R. Typing ^R on a directory file will cause a
430: recursive ^^L. ^^I simply inserts the names of the files into the current
431: buffer.
432:
433: There are also incremental searching modes and pattern matching search modes,
434: described separately.
435: **** Searching ****
436:
437: **** Init files ****
438: TED executes the file ".ted_init" in your login directory when it first starts
439: up. That is, it executes the characters in ".ted_init" just as if you typed
440: them at the keyboard. This allows you to set up various options any way you
441: want automatically.
442:
443: A typical ".ted_init" might be:
444:
445: ^X^SS^X^KS^V25%^]64W^]64B
446:
447: This particular example turns on incremental search mode and alternate ^K mode,
448: forces the last screenful of a file to display 25% blank (it is normally
449: displayed 70% blank), sets the paragraph fill width to 64 characters, and turns
450: on auto-break mode by setting the break limit at 64 characters.
451:
452: For readability, your ".ted_init" can be split into several lines. Newlines
453: are discarded, except that a blank line is converted to ^J. Hence, a ^J must
454: be represented by two ^J's.
455:
456: Note that these files must contain all of the ^Q's you would normally have to
457: type to get control characters into string arguments such as macro bodies and
458: search patterns. For example, to define ^Y^L to be ^U-^L, a file would have to
459: contain the following:
460:
461: ^Y^@^L^Q^U-^Q^L^M
462: **** Init files ****
463:
464: **** Running programs ****
465: The ^J command allows the user to run programs interactively from TED without
466: leaving the editor environment, so that TED can be used like a primitive shell.
467: The ^J command asks for a program name, and if there is currently no inferior
468: for the program, asks for a command line and then starts the program. If there
469: is an inferior for the program, the inferior is continued. The default program
470: name is the most recently stopped inferior. If there are no stopped inferiors,
471: the value of the string variable "default_fork" is used, with default value
472: "debug". The ^U^J command can be used to kill an inferior that cannot
473: otherwise be terminated.
474:
475: If the "pause" number variable is non-zero, TED will not clear the screen after
476: an inferior terminates until the next command is typed. This allows you to
477: look over the output of inferiors that you do not actually interact with.
478:
479: The ^\ command also allows the user to run certain kinds of programs from TED
480: without leaving the editor environment. The options of this command provide a
481: simple interface to allow the user to do the following:
482:
483: I,Q: Indent current file.
484: C,H,J,K,O,U: Compile files.
485: D,L,P,R,V,X: Format current file using R20.
486: E: Format current file using Scribe.
487: M: Makefile.
488: S: Send contents of current file as mail.
489: Y: Run arbitrary program with the contents of
490: the current file as input.
491: Z: Run arbitrary program with the name of
492: the current file as JCL, or with arbitrary JCL.
493: A,B: Type or insert the last report from the above.
494: W: Change working directory.
495:
496: Many of the options run separate programs. While a separate program is running
497: TED prints the amount of real time that has elapsed. A ^G typed at TED can
498: abort a runaway program (the user will be asked for definite confirmation). In
499: general, before running a separate program, if the current file has been
500: changed since it was last read or written, then the file is automatically
501: written to a new version. After executing an option, any results are
502: automatically displayed. These results are retained in a buffer named
503: "Result", and may be redisplayed later with the A option or inserted in the
504: current buffer with the B option. If the results contain errors keyed by line
505: number, you can move to a particular line with the ^V#L command.
506:
507: The CLU/Argus indenter operates either on the whole file (the I option) or on
508: the text starting to the right of the current cursor (the Q option), performing
509: fairly complete syntax checking of programs as well as attempting to indent
510: code attractively. Errors are reported as if a separate program were run,
511: although a separate program is not run. The Q option will indent a specified
512: number of textual "units", where a unit is basically a module, routine, equate,
513: statement, expression list, or expression. The text to the right of the cursor
514: should start such a unit. The indentation of the current line is assumed to be
515: correct; it is not derived from context. Indentation is controlled by a number
516: of variables, settable via ^XI.
517:
518: The CLU or Argus compiler can be run as an inferior process to compile
519: programs. The most common usage (the C option) is to compile the current
520: buffer contents, first writing them out if the buffer has been changed since it
521: was last read or written. The O option is like C, but causes an optimizing
522: compilation. The U option will write out all changed files and then run the
523: compiler on just those, all files, or all files with out-of-date binary files,
524: or files with out-of-date binaries from a specified list. There are a number
525: of options under the U option to specify the compilation mode (normal
526: compilation, optimization, type-check, etc.) Explicit compiler commands can be
527: passed to the compiler via the J option. Giving a zero argument with the J
528: option prevents the current file from being written out. For the C and O
529: options, the suffix must be "clu" (or "arg"), "equ", "xfile", "spc", or "";
530: these cause COMPILE, CE, XFILE, SPECS, and COMPILE compiler commands,
531: respectively. The K option either keeps or kills a compiler. If the compiler
532: is kept, the type-checking will usually be more complete. The compiler should
533: generally be kept while compiling files from the same program. When finding
534: out-of-date binaries, the default suffix "bin", although this can be controlled
535: with the "binary_suffix" variable; the default directory is the source
536: directory, but this can be controlled with the "binary_dir" variable, which can
537: specify a directory relative to the source directory. The N option can be used
538: to change the name of the compiler.
539:
540: The text formatter "R" can be used to format the current file in six ways. The
541: D option formats it for the DIABLO, the L option formats it for the line
542: printer, the P option produces PRESS format, the X option formats it for the
543: XGP, the V options formats it for the Varian, and the R option allows the user
544: to give explicit commands. Giving a zero argument with the R option prevents
545: the current file from being written out. The name of the program R is defined
546: by the string variable "r_name", default value "r". The program name can
547: contain a directory specification. In addition, "r_name" can specify a
548: constant prefix to be added to the command line, by appending the prefix,
549: separated by a space, to the program name.
550:
551: The E option can be used to run the text formatter "Scribe". The name of the
552: program Scribe is defined by the string variable "scribe_name", default value
553: "scribe". The program name can contain a directory specification.
554:
555: The M option can be used to execute a "make" command.
556:
557: TED can be used to compose and send mail. Just type the text of the message
558: into the buffer, and then use ^\S. If you want a subject heading, just start
559: the first line of the message with "Subject: ". You will be prompted for the
560: addresses to send the message to. The name of the mail program is defined by
561: the string variable "mail_name", default value "/usr/lib/sendmail". The
562: program name can contain a directory specification. In addition, "mail_name"
563: can specify a constant prefix to be added to the command line, by appending the
564: prefix, separated by a space, to the program name.
565:
566: An (almost) arbitrary program can be run with the name of the current file as
567: JCL (but with no primary input) via the Z option. The program can be run with
568: arbitrary JCL via ^\0Z. The name of the program is defined by the string
569: variable "progz_name". The program name can contain a directory specification.
570: In addition, "progz_name" can specify a constant prefix to be added to the
571: command line, by appending the prefix, separated by a space, to the program
572: name.
573:
574: An (almost) arbitrary program can be run with arbitrary JCL and the contents of
575: the current file as primary input via the Y option. The name of the program is
576: defined by the string variable "progy_name". The program name can contain a
577: directory specification. In addition, "progy_name" can specify a constant
578: prefix to be added to the command line, by appending the prefix, separated by a
579: space, to the program name. Beware that a single process is sending input to
580: the program and collecting output, so it is possible to deadlock.
581: **** Running programs ****
582:
583: **** Adjusting text ****
584: Text can be adjusted simply in TED using the ^] command. The user can adjust a
585: marked region of text (M), a region of comments (contiguous lines with the same
586: initial non-blank character) (C), a paragraph (P), or a region of the next N
587: lines (N). In addition, the width to use when adjusting can be set (by default
588: it is 64) (W). The text is justified "ragged right" by default, in that no
589: extra spaces are inserted to align the text on the right margin. However, the
590: justification mode can be changed to insert extra spaces to produce even left
591: and right margins (J). Formatter lines (blank lines and lines starting with a
592: character in the "no_fill_starters" string variable) will not be adjusted.
593: Paragraph justification works only on non-indented paragraphs, i.e., only the
594: first line of the paragraph may contain leading spaces or tabs.
595:
596: Text (or comments) may also be justified as it is being entered. This is
597: auto-break mode, and may be set by specifying a width to break at when entering
598: text (B). A fill prefix may also be specified (A).
599:
600: The marked text can be left (L), right (R), or center (E) justified within a
601: fixed width field. The absolute value of the numeric argument specifies the
602: field width. When right or center justifying multiple lines, or when center
603: justifying the end of a single line, the field will not be padded out on the
604: right with spaces unless a negative argument is specified.
605:
606: There is also an auto-indent mode (I), in which typing carriage return causes
607: blank space, equal in width to the leading blank space of the current line, to
608: be inserted at the beginning of the new line. Blank space is also inserted at
609: the beginning of new lines created by auto-break mode. In addition, ^V#^U will
610: change the leading blank space of the current line to be equal in width to the
611: leading blank space of the previous line, plus # additional (or fewer, if # is
612: negative) spaces.
613:
614: The text between the mark and the cursor can be indented or "undented" with
615: ^V#H, where # is the number of spaces to add or subtract. ^V0H has the effect
616: of converting leading spaces to tabs where possible. The remainder of a line
617: starting at the cursor can be moved to start at a particular column with ^V^H.
618: **** Adjusting text ****
619:
620: **** Multi-file buffers ****
621: ^R, ^U^R, and ^U-^R can be used to read several files in to the buffer. The
622: argument to these commands is basically a list of file specifications, which
623: can have *'s in them, where * matches zero or more characters. A real * in a
624: file name can be represented with ^@. The specifications can be separated by
625: commas, spaces, tabs, or newlines. These separators can be included in
626: specifications be preceding them with a backslash (\). All files matching the
627: specifications are read in. Alternatively, a file name (with no *'s in it) may
628: be preceded by an @, in which case the named file is expected to contain a list
629: of file specifications (which can also have @'s in from of them). For ^R, if
630: there is only one matching file, it replaces the current file (the one the
631: cursor is in) in the buffer; if there is more than one matching file, the
632: entire buffer is first flushed. For ^U-^R, all matching files are simply
633: inserted into the buffer. For ^U^R, the text of each matching file is inserted
634: into the current file of the buffer. Note that the default file name applies
635: to all file specifications, including those in @-files.
636:
637: Each file appears in the buffer with a 3 line heading of the form:
638: ^L
639: % <file name>
640: <blank line>
641: These lines cannot be modified.
642:
643: Most TED commands work as before, with (at least) the following exceptions.
644: Text withdrawal only works within a given file; that is, one cannot withdraw
645: text containing parts (or all) of different files. (^U)^R, (^U)^W, and ^\I
646: only affect the current file, i.e., the file containing the cursor. ^Z acts on
647: the current file, and ^U^Z acts on the entire buffer.
648:
649: ^U-^W can be used to write out (only) changed files, with options of using the
650: existing file names or specifying new ones. There are a number of ^V options
651: related to multi-file buffers. ^VA moves to the start of the current file, ^VE
652: move to the end of the current file, ^VN moves to the start of the next file,
653: ^VP moves to the start of the previous file, ^V#@ moves to line # of the
654: buffer, ^V^K deletes the current file from the buffer, and ^VO inserts space
655: for a new file. ^VV displays the file number and name of the current file, the
656: file and buffer line numbers of the current cursor position, and the column and
657: character numbers of the current cursor position. There is also a ^\ option
658: related to multi-file buffers. ^\G takes the current file, which should be a
659: CLU or Argus file, and splits it into a several files, each containing one
660: module.
661:
662: While working on a multi-file buffer, all changed files will be written to the
663: ted save file. If the system crashes, simply reading in your ted save file
664: will not get you back to a multi-file buffer. To separate out individual
665: files, see "~CLU/restore.macro".
666: **** Multi-file buffers ****
667:
668: **** Multiple buffers ****
669: When you first start up a TED, you are working in a buffer named "Main". It is
670: possible to have multiple named buffers around, and to switch between them.
671: Only one buffer is displayed in a window at one time, and any buffer can have
672: multiple files in it. Multiple buffers are an alternative to multi-file
673: buffers, and both are useful on occasion.
674:
675: The multiple buffer commands are under ^X^H. There are commands for creating
676: and destroying buffers and for switching between them, for moving text between
677: buffers, and for displaying the status of all buffers. All buffers are kept in
678: a ring structure, and several commands work on the basis of ring order.
679:
680: ^B asks for a buffer name, and displays that buffer if it exists, else
681: creates and displays a new empty buffer of that name.
682: ^D displays a list of all buffers and the files in those buffers, and
683: indicates if they have been modified since last written.
684: ^F flips to the buffer previously displayed in the window, if any, else
685: the previous buffer in the ring.
686: ^H asks for a string and displays the next buffer in the ring whose name
687: contains that string as a substring.
688: ^K asks for a buffer name and kills the specified buffer unless it is
689: being displayed by another window. Confirmation must be given if the
690: buffer has been modified. If the buffer is being displayed in the
691: current window, a new buffer is chosen for display.
692: ^N displays the #'th next buffer in the ring
693: ^P displays the #'th previous buffer in the ring
694: ^R asks for a list of files, creates (if necessary) a buffer whose name is
695: derived from the list, reads the files into the buffer, and displays
696: the buffer. If the buffer already exists and has been modified,
697: confirmation must be given. For a single file specification, the
698: buffer name is the name.suffix pair of the file specification. For a
699: list of file specifications, a new buffer is always created, and will
700: be "Main" followed by digits.
701: ^S,S appends text from the current buffer to the end of a named buffer
702: (default "Temp"). ^S appends # lines, S appends the marked text. The
703: text is not deleted from the current buffer. The named buffer is
704: created if it does not exist.
705: ^W,W withdraws text from the current buffer and appends it to a named buffer
706: (default "Temp"). ^W withdraws # lines, W withdraws the marked text.
707: The named buffer is created if it does not exist.
708: C writes out all changed files in all buffers, prompting for a new name
709: for each file. Typing ^G for a particular file will not write it out.
710: If # is zero, existing names for files will be used with no prompting.
711: I inserts the text of the named buffer at the cursor of the current
712: buffer. The text is not removed from the named buffer.
713: **** Multiple buffers ****
714:
715: **** Multiple windows ****
716: In addition to multiple buffers, it is also possible to have multiple windows.
717: Each window displays a single buffer, but different windows can display the
718: same buffer if desired. Editing can only be done in one window at a time,
719: though other windows can be scrolled. The "cursor" is a per buffer notion, not
720: a per window notion.
721:
722: One possible use of multiple windows is during compilation or formatting. The
723: result of a ^\ command is saved in a buffer named "Result". When you get error
724: messages, you can create a second window and display the Result buffer in it.
725: Then you can fix the errors in one window while scrolling to new error messages
726: in the other window. This is often much more convenient than constantly
727: flipping back and forth with ^\A.
728:
729: The multiple window commands are under ^X^W. There are commands for splitting
730: the current window and killing the current window, for moving to a new window,
731: for changing the size of existing windows, and for scrolling windows. Windows
732: are kept in a ring structure, and several commands work on the basis of ring
733: order.
734:
735: ^B moves the bottom boundary of current window down # lines. A negative #
736: means move up. Fails on bottom window.
737: ^K kills the current window (but not the buffer it displayed). The new
738: editing window is the window above, if any, else the window below.
739: Space from the killed window is added to the new editing window. The
740: cursor will be moved if necessary to reside in the part of the buffer
741: currently displayed in the new editing window.
742: ^N selects a new editing window by moving down (and around) # windows.
743: The cursor will be moved if necessary to reside in the part of the
744: buffer currently displayed in that window.
745: ^P selects a new editing window by moving up (and around) # windows. The
746: cursor will be moved if necessary to reside in the part of the buffer
747: currently displayed in that window.
748: ^R asks for a list of files, creates (if necessary) a buffer whose name is
749: derived from the list, reads the files into the buffer, splits the
750: current window, and displays the new buffer in the new, lower window.
751: The new window contains |#| text lines if # is not 0 or 1, otherwise
752: the current window is split in half. The new window becomes the
753: editing window. If the buffer already exists and has been modified,
754: confirmation must be given. For a single file specification, the
755: buffer name is the name.suffix pair of the file specification. For a
756: list of file specifications, a new buffer is always created, and will
757: be "Main" followed by digits.
758: ^S asks for a buffer name, creates a new empty buffer of that name if one
759: does not exist, splits the current window, and displays the named
760: buffer in the new, lower window. The new window contains |#| text
761: lines if # is not 0 or 1, otherwise the current window is split in
762: half. The new window becomes the editing window.
763: ^T moves the top boundary of the current window up # lines. A negative #
764: means move down. Fails on the top window.
765: D selects a new editing window by moving down (and around) # windows.
766: The part of the buffer displayed in that window will be changed if
767: necessary to include the cursor.
768: N scrolls the next window down (and around) by # lines if |#|~=1, or by a
769: screenful if |#|=1. Does not move the cursor in any window, and does
770: not change windows.
771: P scrolls the previous window up (and around) by # lines if |#|~=1, or by
772: a screenful if |#|=1. Does not move the cursor in any window, and does
773: not change windows.
774: U selects a new editing window by moving up (and around) # windows. The
775: part of the buffer displayed in that window will be changed if
776: necessary to include the cursor.
777: **** Multiple windows ****
778:
779: **** Incremental search ****
780: Incremental search changes ^S so that it searches for a match dynamically as
781: you type the search string. It is also useful for counting occurrences of a
782: string.
783:
784: ^X^SS changes the search mode to incremental. ^S starts incremental search in
785: Initial mode. This displays a line at the bottom announcing incremental
786: search, and showing you the default. You now have a number of options, based
787: on what character you type:
788:
789: ^D asks for a new default search string.
790: ^H flips the search direction.
791: ^L clears the screen and redisplays.
792: ^O asks for a string and counts the number of occurrences of that string
793: in the rest of the buffer in the search direction.
794: ^S searches forward for the default and enters Search mode.
795: ^U reads a numeric argument as usual, to be applied to the next command
796: whether or not it exits incremental search.
797: ^Y flips sense of whether case is ignored in searches.
798: CR exits incremental search, leaving the cursor where it is.
799: ? displays help.
800:
801: All other control characters (except ^I and ^J) exit incremental search and
802: execute normally. Any other character becomes the first character of the
803: search string and enters Search mode.
804:
805: Once Search mode is entered, ^D and ^O no longer have their special meaning,
806: and ^H and ^Y additionally initiate a search. The only new functions are:
807:
808: ^? (DEL) deletes # characters from the search string and restores the
809: cursor and search direction to their previous values.
810: ^G exits incremental search if the search string is empty, else clears the
811: search string and restores the cursor and search direction to their
812: initial values.
813:
814: As characters are typed in, they are added to the end of the search string, and
815: searching in the current direction is continued. If the desired string is not
816: found, the bell is rung, and the character left in the search string, with an
817: indication that search failed.
818:
819: When incremental search is exited, the search default is set according to the
820: current search string if it is non-empty.
821: **** Incremental search ****
822:
823: **** Macros ****
824: TED has a simple macro facility. A macro is simply a string of characters;
825: executing a macro has basically the same effect as if you typed the characters
826: of the macro directly on the keyboard. There are no conditional or iteration
827: constructs. Commonly used sequences of commands can be turned into macros and
828: defined in your ".ted_init" file, and special macros can be defined on the fly.
829:
830: Macros can be given either string or character names. A character-named macro
831: is defined by typing ^Y^@c (or ^U0^Yc), where 'c' is the character to be used
832: as the name of the macro, followed by the text of the macro. The macro is
833: executed by typing ^Yc, where c is the character naming the macro. ^U#^Yc,
834: with #>0, will execute the macro # times. A string-named macro is defined by
835: typing ^X0^Y, followed by the macro name, followed by the macro body. The
836: macro is executed by typing ^X^Y, followed by the macro name. Typing ^X#^Y,
837: followed by the macro name, will execute the macro # times.
838:
839: During macro execution, an error (anything that would display an "Oops:..." at
840: the top of the screen) will cause the rest macro to be ignored. This is also
841: true of failing searches in incremental search mode.
842:
843: You can also place a macro body in a file, and execute it via the ^X^X command.
844: The format of such a file is the same as your ".ted_init" file, i.e., newlines
845: are discarded, except that a blank line is converted to ^J. Hence, a ^J must
846: be represented by two ^J's.
847: **** Macros ****
848:
849: **** Pattern matching ****
850: In addition to searching for strings, TED has a pattern matching search
851: command, ^X^P. There is also a command, ^^P, for scanning multiple files for a
852: pattern. Within a pattern, it is possible to specify textual deletions,
853: substitutions, and insertions. The grammar for a pattern is as follows:
854:
855: prim ::= sequence of "normal" and quoted characters (^Q char)
856: | ^A | ^B | ^D | ^F | ^J | ^L | ^P | ^X | ^Y | ^Z
857: | ^E^A | ^E^B | ^E^D | ^E^F | ^E^J | ^E^L | ^E^P | ^E^Y
858: | ^R char char | ^K char char | ^\ char ... char ^\
859: | ^V char
860: | ^T text [^T]
861: | ^U name [^U]
862: | ^[ pattern ^]
863: expr ::= prim [^@ | ^^ | ^? | ^_]
864: unit ::= expr
865: | expr ^S text [^S] [^@ | ^^ | ^? | ^_]
866: | expr ^W char [^@ | ^^ | ^? | ^_]
867: | expr ^G macro-body ^G [^@ | ^^ | ^? | ^_]
868: | ^N unit
869: group ::= unit [group]
870: pattern ::= group [^O pattern]
871:
872: Things in square brackets ([]) are optional. All special characters are
873: defined below. All other characters are "normal" characters. Normal
874: characters match themselves. In addition, the case flag for searches also
875: applies to normal characters.
876:
877: ^A matches any alphanumeric character (0-9, A-Z, _, a-z).
878: ^B matches any blank character (space, tab).
879: ^D matches any digit (0-9).
880: ^E can be followed by one of (^A, ^B, ^D, ^F, ^J, ^L, ^P, ^Y), and matches
881: any character not in the range specified by that character. For
882: example, ^E^Y will match only newline.
883: ^F matches any formatting characters (space, tab, formfeed, newline).
884: ^G specifies arbitrary actions to be performed on the part of the buffer
885: matching the previous pattern, in the form of a sequence of characters
886: to be executed just as if they were typed from the terminal. A ^G
887: within the macro-body must be quoted with a ^Q, which will not be
888: removed. Note that the macro-body will not be executed unless the
889: overall pattern matches, and in no way affects the success or failure
890: of matching. The macro-body is executed on a separate buffer
891: containing the match, with the cursor initially at the start of the
892: buffer and the mark at the end of the buffer. The contents of this
893: buffer will be used to replace the match. Note that the macro-body
894: need not modify the buffer; it could, for example, copy the buffer to
895: the end of some other buffer. The macro-body should not generate any
896: errors. If an error does occur within the macro-body, the rest of the
897: macro-body will be ignored, and you will be left in a restricted buffer
898: named Pattern. You should then type ^^ to continue.
899: ^J matches itself, the newline character. Note that newline is not
900: considered a text character, and must be quoted inside ^S and ^T text
901: strings.
902: ^K matches any character not in the range specified by the next two
903: characters. For example, ^Kab would match any character except 'a' and
904: 'b'. The range must be specified with the smallest character first.
905: ^L matches any "letter" (A-Z, _, a-z).
906: ^N NOT construct. This will not actually match anything. It simply
907: guarantees that the following pattern will not match at this point.
908: Note that any text deletion or insertion specified within this
909: construct will be ignored.
910: ^O separates elements of an OR construct. The elements of an OR construct
911: are tried in parallel for the "closest" match. The possible matches
912: for a particular element are always tried in order. The possible
913: matches for all elements are shuffled such that a match M from element
914: E is tried before a match M' from element E' if and only if M is at
915: least as close as M' and E is less than E'. Closeness is determined by
916: the starting position of the match. Thus, if the OR construct must
917: match the immediately following text, the elements are simply tried in
918: order.
919: ^P matches any punctuation (non-alphanumeric) character except newline.
920: ^Q quotes the next character for use as a text character. For example,
921: ^Q^Q will match the character ^Q. Quoting can also be done inside ^G,
922: ^S, ^T, and ^U arguments.
923: ^R matches any character in the range specified by the next two
924: characters. For example, ^R^@^_ matches any control character.
925: ^S substitutes text for the part of the buffer matching the previous
926: pattern. The text can be explicitly terminated with ^S, but will be
927: terminated implicitly by any other special character except ^Q. Note
928: that no substitutions occur unless the overall pattern matches.
929: Substitutions in no way affect the success or failure of matching.
930: ^T inserts text into the buffer. The text can be explicitly terminated
931: with ^T, but will be terminated implicitly by any other special
932: character except ^Q. Note that no insertions occur unless the overall
933: pattern matches. Insertions in no way affect the success or failure of
934: matching.
935: ^U matches the string which is the value of the named string environment
936: variable. If no such variable exists, or is not a string variable,
937: then matches the empty string. The variable name can be explicitly
938: terminated with ^U, but will be terminated implicitly by any other
939: special character except ^Q.
940: ^V inserts the last partial match saved under the label defined by the
941: next character. If no match has been saved, the overall pattern is
942: aborted.
943: ^W deletes and saves the part of the buffer matching the previous pattern
944: under the label defined by the next character. The text can then be
945: inserted using ^V with the same character as the label. Any character
946: can be used as a label. Note that no deletions occur unless the
947: overall pattern matches. Deletions in no way affect the success of
948: failure of matching.
949: ^X matches any character.
950: ^Y matches any character except newline.
951: ^Z matches the end of the buffer.
952: ^@ P^@ matches smallest possible sequence of the pattern P. That is, the
953: patterns <empty>, P, PP, PPP, PPPP, ... are tried in order for the
954: first match that allows the overall pattern to match. For example,
955: ^Y^@ can be used to specify that the remainder of the overall pattern
956: must start matching somewhere on the current line. ^X^@ can be used to
957: specify that the remainder of the overall pattern can start matching
958: arbitrarily far forward in the buffer.
959: ^^ P^^ matches smallest possible non-empty sequence of the pattern P.
960: That is, the patterns P, PP, PPP, PPPP, ... are tried in order for the
961: first match that allows the overall pattern to match. P^^ is
962: equivalent to ^[^[P^]P^@^].
963: ^? (DEL) P^? matches the largest sequence of the pattern P. P^? will
964: match either the longest sequence of P's, or the empty string, but
965: nothing else. For example, ^Y^? will match the rest of the line, and
966: ^X^? will match the rest of the buffer. In situations where ^? and ^@
967: could both be used, ^? is much more efficient.
968: ^_ P^_ matches the largest non-empty sequence of the pattern P. P^_ will
969: match only the longest sequence of P's. P^_ is equivalent to
970: ^[^[P^]P^?^]. In situations where ^_ and ^^ could both be used, ^_ is
971: much more efficient.
972: ^\ ^\ delimits a set of characters; matches any character in the set. For
973: example, ^\+-*/^\ matches '+', '-', '*', or '/'.
974: ^[ ^] are parentheses used to delimit patterns. Used when the normal
975: precedence is not sufficient.
976:
977: Overall, pattern matching retry is performed depth first, right to left. For
978: example, matching the pattern ^[A^OB^]^[X^OY^] would involve, for each match of
979: ^[A^O^B^], trying all possible matches of ^[X^OY^].
980:
981: ^X^P with a positive argument will always add a prefix of ^X^@ (i.e., the match
982: can start arbitrarily far forward in the buffer), and will search # times.
983: ^X^P with a negative argument will always force the match to start at the
984: cursor, and will search |#| times.
985:
986: ^X0^P can be used to turn on/off buffer change confirmation. When turned on,
987: every change to the buffer made under pattern search will have to be confirmed.
988:
989: Beware that it is quite easy to specify patterns that will go either
990: indefinitely or for a very long time before failing or matching the empty
991: string at the end of the buffer. ^G can be used to abort long pattern
992: searches, but you may have to wait a bit before the ^G will be noticed.
993:
994: As an example of the use of pattern matching, the following pattern, when
995: searched via ^X^P, will change the buffer to single spacing:
996:
997: ^[^J^J^_^S^X^@^]^?
998:
999: The following pattern, when searched via ^X-^P, will delete all lines not
1000: containing the string "begin_list" or the string "end_list" (providing the
1001: first line does not contain either string):
1002:
1003: ^[^[^X^@^J^]^S^Y^@^[begin_list^Oend_list^]^Y^?^J^]^?^X^?^S
1004:
1005: The following pattern, when searched via ^X^P, will change the next occurrence
1006: of
1007: if <expr1> cor <expr2>
1008: as a complete single line with arbitrary spacing to
1009: if <expr2> cand <expr1>
1010: with the same spacing:
1011:
1012: ^B^?if^B^_^Y^^^W1^[^B^_cor^Scand^B^_^]^W2^Y^_^V2^V1

1044: **** Pattern matching summary ****
1045:
1046: **** Sorting ****
1047: The ^XX command performs a TECO-like sort of the current file of the buffer.
1048: The file is divided into records of arbitrary length, each of which contains a
1049: sort key, again of arbitrary length and positioned anywhere within the record.
1050: The records may be sorted in increasing lexicographic order with ^XX, or in
1051: decreasing order with ^X-X. Case distinctions are ignored if the search flag
1052: is set to ignore case. The sort is stable (i.e., records with equal keys will
1053: remain in the same relative order), so multi-key sorting can be accomplished by
1054: sorting a key at a time, least significant key first.
1055:
1056: Records and keys are determined using three command strings, given as arguments
1057: to the sort command. The first command string is executed to get from the
1058: start of the current record to the start of its key. The sort will be aborted
1059: if this command string generates any errors. The second command string is
1060: executed to get from the start of the key to the end of the key (i.e., one
1061: character beyond the end of the key). In a failing string or pattern search,
1062: the end of the key (and the end of the record) is assumed to be the end of the
1063: file; any other errors will abort the sort. The third command string is
1064: executed to get from the end of the key to the start of the next record (and is
1065: only executed if the previous command string did not generate an error). In a
1066: failing string or pattern search, the end of the record is assumed to be the
1067: end of the file; any other errors will abort the sort.
1068:
1069: The start of the first record is assumed to be the start of the file. The
1070: command strings are repeatedly executed until the entire file has been divided
1071: into records. The command strings can contain arbitrary commands. The
1072: defaults are (1) the empty string, meaning the key starts at the beginning of
1073: the record, (2) ^E, meaning the end of the key is the end of the first line of
1074: the record, and (3) ^F, meaning the start of the next record is the start of
1075: the next line. This gives a line by line sort of the file.
1076:
1077: Sorting part of a file can be done using the restricted buffer option, ^XR.
1078: **** Sorting ****
1079:
1080: **** Miscellaneous options ****
1081: String and file name arguments normally appear at the bottom of the current
1082: window. Setting the "arg_display_mode" number variable to a non-zero value
1083: will force these arguments to always appear at the bottom of the screen. The
1084: size of the argument window is normally 2 lines. This can be controlled with
1085: the "arg_display_size" number variable.
1086:
1087: Help displays (from ^H and ?) and ^\ result displays normally occupy the entire
1088: screen. Setting the "sub_display_mode" number variable to 1 will cause only
1089: the current window to be used. Setting the variable to 2 will cause the larger
1090: of the two areas above and below the current window to be used, or the entire
1091: screen if there is only one window. Setting the variable to 3 or higher will
1092: cause that many lines at the bottom of the screen to be used. Setting the
1093: variable to 0 or a negative value will restore the use of the full screen.
1094:
1095: You can check the spelling of a word with ^XW. The default argument is the
1096: word containing the cursor, or the word to the left of the cursor if the cursor
1097: is between words. If the word appears to be misspelled, a list of suggested
1098: spellings will be displayed at the top of the screen. Spelling is checked
1099: using ISPELL. The ISPELL process is normally kept around for subsequent
1100: spelling checks, but may be killed off with the ^X0W command.
1101:
1102: ^_D will delete a list of files with a yes/no confirmation on each file, ^_0D
1103: will delete a list of files without confirmation, ^_L will make a link to a
1104: file, ^_S will make a symbolic link to a file, ^_M will change the mode of a
1105: list of files, and ^_R will rename a file.
1106:
1107: ^VT displays the current date and time, and ^V0T inserts the current date and
1108: time into the buffer. ^V^T displays the total CPU time used by TED so far, and
1109: the CPU time used since the last ^V^T command.
1110:
1111: The restricted buffer option (^XR) gives you the piece of the current buffer
1112: between the mark and the cursor as a separate buffer to work on. The changes
1113: get reflected in the original buffer when you exit (via ^^) from this mode.
1114:
1115: There is an alternate mode for ^K, settable via ^X^K, that will only delete to
1116: the end of the line (not through it), unless you are already at the end of the
1117: line or #~=1. There are alternate modes for ^N and ^P, settable via ^XM, that
1118: place the cursor after leading spaces and tabs in the line, a mode for trying
1119: to stay at a fixed column position, and a mode for trying to stay at the column
1120: you were at before the last sequence of ^N and ^P commands.
1121:
1122: There is a mode for text type-in (^XO) that will overwrite characters in the
1123: buffer, rather than inserting characters into the buffer. Type-in
1124: automatically reverts to insertion mode when at the end of a line. Newlines
1125: never overwrite characters; they are always inserted.
1126:
1127: There is a mode for making simple straight line drawings (^X^D). To draw a
1128: line, move the cursor (with ^A, ^E, ^F, ^B, ^N, ^P, ^Z) to the starting point
1129: and set the mark with ^T. Then move the cursor to the ending point and type
1130: the printing character (octal 40 to 176) you want to draw the line with. This
1131: will draw a line from the mark to the cursor, and set the mark to be the end of
1132: the line. To erase a line, just redraw the line with a blank. Drawing a line
1133: will overwrite previous characters unless you type ^U before typing the
1134: printing character.
1135:
1136: There is a command for drawing a box around a group of lines (^XB). The box
1137: can be centered or indented a fixed amount from the left. The shape of the box
1138: is controlled by various "box_*" string and number variables.
1139:
1140: ^XCU and ^XCL change the case of the marked to text to upper and lower case,
1141: respectively. ^XCC capitalizes the first letter of every word in the marked
1142: text.
1143:
1144: The meanings of the RED and BLUE function keys on Heaths and VT52s can be
1145: swapped with ^XE.
1146:
1147: New mail can be tested for with ^X^M.
1148:
1149: ^X#^R will force the # line down (up if negative) from the current (with
1150: respect to where the cursor ought to be, not with respect to where it really
1151: is) line to be redisplayed, and correctly repositions the cursor. This can be
1152: used to clean up lines that have been garbled by system messages or a noisy
1153: terminal line, and is particularly useful over a slow terminal line.
1154:
1155: When editing over a slow line where the system does not know the line speed,
1156: ^XT#B can be used to inform TED that the line speed is # baud. This will
1157: automatically adjust padding appropriately. This number will only be used when
1158: the system does not know the line speed. You can turn padding off with ^XT0P,
1159: and you can prevent TED from using full screen scrolling and insert/delete line
1160: with ^XT0S, although you should never have to do either of these. You can tell
1161: TED your terminal has a meta key with ^XTM, or doesn't have a meta key with
1162: ^XT0M; this controls whether the high bit of each character typed gets masked.
1163: Again, you should never have to do either of these, as the termcap entry should
1164: define this.
1165:
1166: The default position of the cursor on redisplay is 75% up from the bottom of
1167: the window. This percentage can be set with the ^V#^ command, with #<0
1168: restoring the default. When displaying the end of the buffer, the default is
1169: to keep the window 70% blank. This percentage can be set with the ^V#%
1170: command, with #<0 restoring the default. When the cursor moves outside the
1171: current window, the default is to choose a new window around the cursor based
1172: on the above percentages. However, the ^V#= command can be used to alter this,
1173: so that the window will instead be scrolled until the cursor comes into view
1174: (at the top or bottom), provided that # percent of the original window will
1175: remain on the screen. ^V#= with #<0 restores the default (100%).
1176:
1177: You can create your own help file, to be displayed with the ^U^H command. The
1178: string variable "help_file" defines the name of this file, the default being
1179: "~/.ted_hlp". The file can be either a simple text file or a menu-driven file.
1180: For a menu-driven file, the first line must start with "**** Menu for ". The
1181: following lines, up to the next line starting with "**** Menu for ", make up
1182: the menu. Each line of the menu consists of one or more menu items, separated
1183: by tabs. Each menu item consists of an upper-case letter (for selection)
1184: followed by a colon and a space, followed by the name of the selection (e.g.,
1185: "Multiple buffers"). The body of the selection is placed anywhere in the file,
1186: beginning and ending with a line of the form "**** N ****", where N is the name
1187: of the selection.
1188:
1189: The ^X#Z command can be used to control the frequency of garbage collections,
1190: setting a GC to go off every 2**(#-4) megabytes.
1191: **** Miscellaneous options ****
1192:
1193: **** TED variables ****
1194: The following list names the TED variables, their types, and what they are used
1195: for. Number and string variables can be set by ^XN and ^XS, respectively.

1316: **** Indenter variables ****
1317:
1318: **** File names/backup/protection ****
1319: TED accepts ~-form directory specifications and does *-matching. However,
1320: *-matching is a little different than the way the shell does it, in that "."
1321: and ".." are always ignored but other entries beginning with period are not
1322: ignored.
1323:
1324: You can define path name abbreviations with string variables. In file name and
1325: directory arguments, a prefix ending with two slashes (//) is taken to be the
1326: name of a string variable, and is replaced by the value of the variable. For
1327: example, if the string variable "man1//" is defined to be "/usr/man/man1/",
1328: then the file name "man1//csh.1" becomes "/usr/man/man1/csh.1". In ^\J, ^\M,
1329: ^\R, ^\Y, ^\Z, and ^J command lines, words ending with two slashes are also
1330: expanded this way.
1331:
1332: Since Unix does not support version numbers, there are a number of different
1333: ways of creating backup files when files are written. The particular method is
1334: set by the ^X^C command. The options are (N) do not create a backup, and
1335: (over)write directly to the file, (T) do not create a backup, but write to a
1336: temporary file and then rename it (R) always rename the current version of the
1337: file, (^R) rename the current version of the file if a backup does not exist,
1338: otherwise (over)write directly, (^T) rename the current version of the file if
1339: a backup does not exist, otherwise write to a temporary file and then rename
1340: it, (C) always copy the current version of the file before (over)writing
1341: directly, (^C) copy the current version of the file if a backup does not exist
1342: before (over)writing directly, (X) rename the current version of the file
1343: unless there are links to it, in which case copy the current version, and then
1344: (over)write directly, and (^X) if a backup does not exist, rename the current
1345: version of the file unless there are links to it, in which case copy the
1346: current version, and then (over)write directly. The initial mode is N. The
1347: name of the backup file generally is obtained by appending the value of the
1348: "backup_name" string variable to the current file name, with the default being
1349: ".old". However, the current file name may have to be truncated before
1350: appending if the new name exceeds 255 characters. Also, "backup_name" may
1351: contain a (possibly relative) directory where the backup file should be placed.
1352: So "backup_name" should have one of the forms "str", "dir/str", or "dir/".
1353:
1354: If the backup file extension is ".^V", then version numbered backup files are
1355: maintained. When version numbering, the backup-on-write modes ^R, ^T, ^C, and
1356: ^X are equivalent to R, T, C, and X respectively. The "keep_count" number
1357: variable specifies how many backup versions to maintain, with default value 1.
1358: If "keep_count" is N, the N highest versions are kept. If "keep_count" is -N,
1359: then the oldest version and the N-1 highest versions are kept.
1360:
1361: When writing to a file, if you specify a name longer than 255 characters, the
1362: number variable "write_check" controls what happens. If the variable is 0 (the
1363: default), the name is truncated in the usual way. If the variable is negative,
1364: the file is not written and an error message is generated. If the variable is
1365: positive, the part before the first dot is truncated, unless the part after the
1366: first dot is longer than 254 characters, in which case the file is not written
1367: and an error message is generated.
1368:
1369: The mode bits for new files are given by the "write_mode" octal number
1370: variable, the default being 666 masked by the initial umask. The umask is then
1371: cleared, but its value is saved in the "umask" octal number variable, for use
1372: when running inferiors. The mode bits for ted save files is given by the
1373: "save_mode" octal number variable, with the default being 600.

1376: **** XTED features ****
1377: This section is for those using the version of TED that runs under the X window
1378: system.
1379:
1380: The following are options that can be specified at the beginning of the command
1381: line when starting an XTED:
1382: -fn=FONT
1383: [-HOST]:DISPLAY
1384: =[WIDTH][xHEIGHT][{+-}XOFF[{+-}YOFF]]
1385: -rv (reverse video)
1386: -i (miniature icon)
1387: -fg=COLOR (text color)
1388: -bg=COLOR (background color)
1389: -cr=COLOR (text cursor color)
1390: -hl=COLOR (highlight color)
1391: -ms=COLOR (mouse cursor color)
1392:
1393: The []'s denote optional stuff, the {}'s surround alternatives. The default
1394: font is 8x13, the default display is controlled by the DISPLAY environment
1395: variable. WIDTH and HEIGHT are in number of characters, XOFF and YOFF are in
1396: pixels. WIDTH defaults to 80, HEIGHT to 24, XOFF and YOFF to 1. If you don't
1397: give XOFF and/or YOFF, then you must use the mouse to create the window.
1398: Pressing left button will give you a WIDTHxHEIGHT window that you can then move
1399: around to place until you release the button. Pressing the right button gives
1400: you a window WIDTH wide and to the bottom of the screen. Pressing the middle
1401: button defines one corner of the window, releasing the button defines the
1402: opposite corner. If you give XOFF and/or YOFF, then a WIDTHxHEIGHT window will
1403: automatically be creating without intervention. XOFF and YOFF specify deltas
1404: from a corner of the screen to the corresponding corner of the window, as
1405: follows:
1406: +XOFF+YOFF upper left to upper left
1407: -XOFF+YOFF upper right to upper right
1408: +XOFF-YOFF lower left to lower left
1409: -XOFF-YOFF lower right to lower right
1410:
1411: The following options are also read from the .Xdefaults file: BodyFont,
1412: BorderWidth, ReverseVideo, Foreground, Background, Cursor, Highlight, and
1413: Mouse.
1414:
1415: The ^C command does not suspend XTED, as suspending is useless. Instead, ^C
1416: should be typed after resizing the window, to reconfigure things. (Someday
1417: maybe this will be automatic.)
1418:
1419: The ^J command for interactive programs does not exist: run them in another
1420: window!
1421:
1422: The command ^XT0C will change the window to white text on a black background.
1423: The command ^XTC restores the window to black text on a white background.
1424:
1425: The escape sequences generated by mouse button events are as follows:
1426:
1427: &l left-down
1428: &L left-up
1429: &a CONTROL-left-down
1430: &A CONTROL-left-up
1431: &b SHIFT-left-down
1432: &B SHIFT-left-up
1433: &d META-left-down
1434: &D META-left-up
1435: &e CONTROL-SHIFT-left-down
1436: &E CONTROL-SHIFT-left-up
1437: &f META-SHIFT-left-down
1438: &F META-SHIFT-left-up
1439: &g CONTROL-META-left-down
1440: &G CONTROL-META-left-up
1441:
1442: &m middle-down
1443: &M middle-up
1444: &h CONTROL-middle-down
1445: &H CONTROL-middle-up
1446: &i SHIFT-middle-down
1447: &I SHIFT-middle-up
1448: &j META-middle-down
1449: &J META-middle-up
1450: &k CONTROL-SHIFT-middle-down
1451: &K CONTROL-SHIFT-middle-up
1452: &n META-SHIFT-middle-down
1453: &N META-SHIFT-middle-up
1454: &o CONTROL-META-middle-down
1455: &O CONTROL-META-middle-up
1456:
1457: &r right-down
1458: &R right-up
1459: &p CONTROL-right-down
1460: &P CONTROL-right-up
1461: &q SHIFT-right-down
1462: &Q SHIFT-right-up
1463: &s META-right-down
1464: &S META-right-up
1465: &u CONTROL-SHIFT-right-down
1466: &U CONTROL-SHIFT-right-up
1467: &v META-SHIFT-right-down
1468: &V META-SHIFT-right-up
1469: &x CONTROL-META-right-down
1470: &X CONTROL-META-right-up
1471:
1472: Note that META-L is shown as &L, etc. (On a VS100 keyboard, the Symbol key is
1473: the META key, so for example you type META-l by holding down the Symbol key and
1474: pressing the L key, and META-L by holding down the Shift key and the Symbol key
1475: and pressing the L key.)
1476:
1477: The default action for these escape sequences is to do nothing, but you can
1478: define them as any sequence of characters in the same way you would (re)define
1479: any escape sequence. Additional escape sequences are available for defining
1480: the buttons:
1481: &c scrolls the window so that the cursor ends up on the same line as the
1482: last/current button event. This line must be within the same window as
1483: the cursor or an error will result.
1484: &C sets the cursor to the position of the last/current button event. This
1485: position must be within the same window as the cursor or an error will
1486: result.
1487: &t turns on tracking of the mouse and highlighting of the text between the
1488: cursor and the mouse if #>0, and turns tracking off if #<=0.
1489: Highlighting is performed by underlining if #=1, and by inverse video
1490: if #>1.
1491: &T sets the mark to the position of the last/current button event. This
1492: position must be within the same window as the cursor or an error will
1493: result.
1494: &w is equivalent to doing a ^X^W#D into the window containing the
1495: last/current button event position. This position must be within some
1496: window or an error will result.
1497: &W is equivalent to doing a ^X^W#^N into the window containing the
1498: last/current button event position. This position must be within some
1499: window or an error will result.
1500: &Y inserts the window system global cut buffer |#| times at the cursor
1501: (#<0 inserts before the cursor
1502: &z stores the current saved text in the window system global cut buffer.
1503: &Z stores the current deleted text in the window system global cut buffer.
1504:
1505: For example, with the following lines in your .ted_init, you can delete a
1506: highlighted region of text by placing the mouse on the first character of the
1507: text, pressing the left button down, moving to just after the last character of
1508: the text, and raising the button:
1509:
1510: ^[^[&l^Q^[^Q&W^Q^[^Q&C^Q^[^Q&t^M
1511: ^[^[&L^Q^U0^Q^[^Q&t^Q^[^Q&T^Q^VW^M
1512:
1513:
1514: By default, the various function and keypad keys transmit the following
1515: characters. Note that the character META-c as a command gets interpreted the
1516: same as the sequence "ESC c".
