16: .SH DESCRIPTION
17: .PP
18: .I Graw
19: is a multi-file graphic editing program specialized for schematic entry.
20: .I Graw
21: drawings consist of lines, boxes, text objects, and instantiations of previously
22: defined drawings called
23: .I masters.
24: The
25: .I graw
26: user interface differs from that of most 5620/gnot programs in that button 1
27: controls
28: .I all
29: graphical entry.
30: .PP
31: The
32: .B -g
33: flag invokes an experimental mode in which
34: .B graw
35: attempts to render in grey scale.
36: The
37: .B -f
38: flag allows the user to specify a font for displaying text objects.
39: .PP
40: By default, pressing button 1 will create a line with one end fixed and the other
41: end attached to the cursor as long as button 1 is held down. Objects other than
42: lines can be drawn by prefacing a drawing operation with a button 2
43: .B onesies\(->
44: selection.
45: Button 1 is also used for
46: .I grabbing
47: objects. Grabbing takes precedence over drawing, and
48: .I graw
49: evaluates every button 1 hit to see if there is something to grab.
50: .PP
51: Grabbing rules vary by object. For example, a box can be grabbed by pointing to
52: its interior. A grabbed box will cause all objects inside or touching it to be
53: grabbed also. Grabbing a box's corner will also grab objects touching the two
54: sides of that corner. An object inside a box may be grabbed without grabbing
55: the box.
56: .I Graw's
57: grabbing rules are meant to be intuitively obvious. The author apologizes for
58: cases in which this is not true.
59: .PP
60: .I Graw
61: keeps a "text point" at the last location of a button 1 hit.
62: Typing to
63: .I graw
64: creates a text object at the current text point.
65: A text object orients itself based on its surroundings each time it is typed
66: at or moved.
67: Typing a carriage return causes graw to move the current text point down one or
68: two ticks, depending on the surroundings.
69: .PP
70: Buttons 2 and 3 contain editing and file oriented menus, respectively.
71: The button 2 menu entries are
72: .B onesies\(-> (box, dots, macro),
73: .B inst\(->
74: .I (master list),
75: .B sweep, slash, cut, paste,
76: and
77: .B scroll.
78: .RS
79: .TP
80: .B onesies\(->
81: selects a non-line object to be drawn with button 1.
82: You get at most one non-line object per onesie.
83: .TP
84: .B inst\(->
85: selects a master to be instantiated and attached to the cursor until any button
86: is pressed.
87: .TP
88: .B sweep
89: uses a rectangle input with button 1 (N.B.) to grab a set of objects and drag
90: them until any button is pressed.
91: .TP
92: .B slash
93: differs from
94: .B sweep
95: only in that rectilinear lines are first cut by the input rectangle.
96: .TP
97: .B cut
98: undraws and moves the object(s) last drawn or moved to the cut/paste buffer.
99: .TP
100: .B paste
101: attaches a copy of the cut/paste buffer to the cursor until any button is
102: pressed.
103: .TP
104: .B snarf
105: is a
106: .B cut
107: without the undraw.
108: .TP
109: .B scroll
110: attaches the entire drawing to the cursor until any button is pressed.
111: .RE
112: .PP
113: The button 3 menu entries are
114: .B edit, read, write, exit,
115: and
116: .B new,
117: followed by the list of filenames currently being edited.
118: .RS
119: .TP
120: .B edit
121: prompts for a file name and reads in the file for editing. Backspace and
122: control-W may be used to edit the name; a null file name aborts the operation.
123: .TP
124: .B read
125: prompts for the name of a master file, reads it in, and plants a reference to
126: it in the current file. The names of the masters in the file are added to
127: those in the
128: .B inst\(->
129: menu for the current file, overwriting older definitions if necessary.
130: .TP
131: .B write
132: prompts for a file name (starting with the current file name). The non-null
133: result becomes the new file name and the file is written.
134: .TP
135: .B exit
136: terminates the program. It may be necessary to type a character and/or move the
137: mouse after
138: .I graw
139: exits to really exit.
140: .TP
141: .B new
142: creates a new, unnamed drawing for editing.
143: .PP
144: Selecting a file name selects the current file.
145: .RE
146: .PP
147: .I Graw
148: can read
149: .I jraw
150: format files. Conversion from
151: .I jraw
152: to
153: .I graw
154: begins with this step and is generally completed by removing library master
155: instantiations from the resulting
156: .I graw
157: format file.
158: .PP
159: .I Jraw -w
160: produces ucds netlist format from
161: .I graw
162: format files.
163: .PP
164: .I Jb
165: produces postscript from
166: .I graw
167: format files.
