Annotation of researchv10no/cmd/troff/dev202/catalog, revision 1.1.1.1

1.1       root        1: .TL
                      2: Linotron 202 Font Catalog
                      3: .AU
                      4: Brian Kernighan
                      5: Ken Thompson
                      6: .PP
                      7: The new 202 is more or less working,
                      8: and some order has been brought out of
                      9: font chaos.
                     10: The attached pages list all of the characters
                     11: currently available on the 202.
                     12: Note that availability on the 202 does not
                     13: imply availability on the Canon printers
                     14: or on the MHCC APS-5.
                     15: .PP
                     16: The 202 has two floppy disk drives.
                     17: We have about 130 fonts, and
                     18: a single diskette can hold roughly 40-50 fonts.
                     19: The typesetter is normally run with one diskette
                     20: but can can be run with two.
                     21: Accordingly, the fonts have been divided into three
                     22: groups:
                     23: common and/or new and/or interesting;
                     24: less so;
                     25: rare and/or old and/or boring.
                     26: The division was made capriciously and arbitrarily
                     27: but is not likely to change in the near future.
                     28: In any case, the result is that fonts in
                     29: category 1 will always be available,
                     30: fonts in category 2 will probably be available,
                     31: and fonts in category 3 will not be unless
                     32: you replace a diskette and reboot.
                     33: And of course you get to use fonts from only
                     34: two diskettes in any one job.
                     35: .PP
                     36: To make all this work,
                     37: some changes have been made in troff as well.
                     38: Since two-character names
                     39: can't cope with 130+ fonts,
                     40: the .fp command in troff now accepts
                     41: a third argument to specify a ``real'' name
                     42: for a font.
                     43: It is used like this:
                     44: .DS
                     45:        .fp 1 R Gillsans
                     46:        .fp 2 I GillsansI
                     47:        .fp 3 B GillsansB
                     48: .DE
                     49: which makes R, I and B synonyms for the corresponding
                     50: Gill Sans fonts.
                     51: You can use any one or two-letter names instead of
                     52: R, I and B.
                     53: .PP
                     54: .fp 1 R Gillsans
                     55: .fp 2 I GillsansI
                     56: .fp 3 B GillsansB
                     57: (This font is Gill Sans, in case anyone is interested;
                     58: .ft I
                     59: this is Gill Sans Italic;
                     60: .ft B
                     61: and this is Gill Sans Bold.)
                     62: .PP
                     63: .FP times
                     64: Since many fonts consist entirely of weird nameless
                     65: characters (look at Chempi, for example),
                     66: troff now permits access to characters by their absolute number
                     67: on a font: \eN\(fm123\(fm refers to character 123 on
                     68: the current font.
                     69: The lists here show the absolute number for each character
                     70: that does not have a real name.
                     71: .PP
                     72: In the following listings, each font is introduced by
                     73: a header of the form
                     74: .DS
                     75:        ZapfI 92 Zapf Book Light Italic
                     76: .DE
                     77: The first word is the troff name of the font, suitable
                     78: for use in a .fp command.
                     79: The number (92) is for internal use by d202.
                     80: The rest of the line is the ``official'' descriptive name
                     81: of the font, suitable for talking to typographers.
                     82: .PP
                     83: This is all somewhat tentative,
                     84: so don't build anything too complicated
                     85: on top of it.
                     86: Complaints to bwk.
