37 cfa37a7b 2004-04-10 devnull .SH DESCRIPTION
39 cfa37a7b 2004-04-10 devnull manages windows of text that may be edited interactively or by external programs.
40 cfa37a7b 2004-04-10 devnull The interactive interface uses the keyboard and mouse; external programs
41 cfa37a7b 2004-04-10 devnull use a set of files served by
42 cfa37a7b 2004-04-10 devnull .IR acme ;
43 cfa37a7b 2004-04-10 devnull these are discussed in
44 cfa37a7b 2004-04-10 devnull .IR acme (4).
46 cfa37a7b 2004-04-10 devnull Any named
48 cfa37a7b 2004-04-10 devnull are read into
50 cfa37a7b 2004-04-10 devnull windows before
52 cfa37a7b 2004-04-10 devnull accepts input.
55 cfa37a7b 2004-04-10 devnull option, the state of the entire system is loaded
57 cfa37a7b 2004-04-10 devnull .IR file ,
58 cfa37a7b 2004-04-10 devnull which should have been created by a
60 cfa37a7b 2004-04-10 devnull command (q.v.),
61 cfa37a7b 2004-04-10 devnull and subsequent
63 cfa37a7b 2004-04-10 devnull names are ignored.
64 cfa37a7b 2004-04-10 devnull Plain files display as text; directories display as columnated lists of the
65 cfa37a7b 2004-04-10 devnull names of their components, as in
66 cfa37a7b 2004-04-10 devnull .B "ls -p directory|mc
67 cfa37a7b 2004-04-10 devnull except that the names of subdirectories have a slash appended.
71 cfa37a7b 2004-04-10 devnull .RB ( -F )
72 cfa37a7b 2004-04-10 devnull option sets the main font, usually variable-pitch (alternate, usually fixed-pitch);
73 cfa37a7b 2004-04-10 devnull the default is
74 adc93f60 2005-01-14 devnull .B \*9/font/lucidasans/euro.8.font
75 cfa37a7b 2004-04-10 devnull .RB ( \&.../lucm/unicode.9.font ).
76 cfa37a7b 2004-04-10 devnull Tab intervals are set to the width of 4 (or the value of
77 cfa37a7b 2004-04-10 devnull .BR $tabstop )
78 cfa37a7b 2004-04-10 devnull numeral zeros in the appropriate font.
80 cfa37a7b 2004-04-10 devnull .SS Windows
82 cfa37a7b 2004-04-10 devnull windows are in two parts: a one-line
84 cfa37a7b 2004-04-10 devnull above a multi-line
85 cfa37a7b 2004-04-10 devnull .IR body .
86 cfa37a7b 2004-04-10 devnull The body typically contains an image of a file, as in
87 cfa37a7b 2004-04-10 devnull .IR sam (1),
88 cfa37a7b 2004-04-10 devnull or the output of a
89 cfa37a7b 2004-04-10 devnull program, as in an
90 cfa37a7b 2004-04-10 devnull .IR rio (1)
92 cfa37a7b 2004-04-10 devnull The tag contains a number of
93 cfa37a7b 2004-04-10 devnull blank-separated words, followed by a vertical bar character, followed by anything.
94 cfa37a7b 2004-04-10 devnull The first word is the name of the window, typically the name of the associated
95 cfa37a7b 2004-04-10 devnull file or directory, and the other words are commands available in that window.
96 cfa37a7b 2004-04-10 devnull Any text may be added after the bar; examples are strings to search for or
97 cfa37a7b 2004-04-10 devnull commands to execute in that window.
98 cfa37a7b 2004-04-10 devnull Changes to the text left of the bar will be ignored,
99 cfa37a7b 2004-04-10 devnull unless the result is to change the name of the
102 cfa37a7b 2004-04-10 devnull If a window holds a directory, the name (first word of the tag) will end with
103 cfa37a7b 2004-04-10 devnull a slash.
104 cfa37a7b 2004-04-10 devnull .SS Scrolling
105 cfa37a7b 2004-04-10 devnull Each window has a scroll bar to the left of the body.
106 cfa37a7b 2004-04-10 devnull The scroll bar behaves much as in
107 cfa37a7b 2004-04-10 devnull .IR sam (1)
109 cfa37a7b 2004-04-10 devnull .IR rio (1)
110 cfa37a7b 2004-04-10 devnull except that scrolling occurs when the button is pressed, rather than released,
111 cfa37a7b 2004-04-10 devnull and continues
112 cfa37a7b 2004-04-10 devnull as long as the mouse button is held down in the scroll bar.
113 cfa37a7b 2004-04-10 devnull For example, to scroll slowly through a file,
114 cfa37a7b 2004-04-10 devnull hold button 3 down near the top of the scroll bar. Moving the mouse
115 cfa37a7b 2004-04-10 devnull down the scroll bar speeds up the rate of scrolling.
116 a965f2ed 2005-01-10 devnull (The experimental option
118 a965f2ed 2005-01-10 devnull reverses the scrolling behavior of buttons 1 and 3, to behave
119 a965f2ed 2005-01-10 devnull more like
120 a965f2ed 2005-01-10 devnull .IR xterm (1).)
121 cfa37a7b 2004-04-10 devnull .SS Layout
123 cfa37a7b 2004-04-10 devnull windows are arranged in columns. By default, it creates two columns when starting;
124 cfa37a7b 2004-04-10 devnull this can be overridden with the
127 cfa37a7b 2004-04-10 devnull Placement is automatic but may be adjusted
128 cfa37a7b 2004-04-10 devnull using the
129 cfa37a7b 2004-04-10 devnull .I layout box
130 cfa37a7b 2004-04-10 devnull in the upper left corner of each window and column.
131 cfa37a7b 2004-04-10 devnull Pressing and holding any mouse button in the box drags
132 cfa37a7b 2004-04-10 devnull the associated window or column.
133 cfa37a7b 2004-04-10 devnull For windows, just
134 cfa37a7b 2004-04-10 devnull clicking in the layout box grows the window in place: button 1
135 cfa37a7b 2004-04-10 devnull grows it a little, button 2 grows it as much as it can, still leaving all other
136 cfa37a7b 2004-04-10 devnull tags in that column visible, and button 3 takes over the column completely,
137 cfa37a7b 2004-04-10 devnull temporarily hiding other windows in the column.
138 cfa37a7b 2004-04-10 devnull (They will return
139 cfa37a7b 2004-04-10 devnull .I en masse
140 cfa37a7b 2004-04-10 devnull if any of them needs attention.)
141 cfa37a7b 2004-04-10 devnull The layout box in a window is normally white; when it is black in the center,
142 cfa37a7b 2004-04-10 devnull it records that the file is `dirty':
144 cfa37a7b 2004-04-10 devnull believes it is modified from its original
145 cfa37a7b 2004-04-10 devnull contents.
147 cfa37a7b 2004-04-10 devnull Tags exist at the top of each column and across the whole display.
149 cfa37a7b 2004-04-10 devnull pre-loads them with useful commands.
150 cfa37a7b 2004-04-10 devnull Also, the tag across the top maintains a list of executing long-running commands.
151 cfa37a7b 2004-04-10 devnull .SS Typing
152 cfa37a7b 2004-04-10 devnull The behavior of typed text is similar to that in
153 cfa37a7b 2004-04-10 devnull .IR rio (1)
154 cfa37a7b 2004-04-10 devnull except that the characters are delivered to the tag or body under the mouse; there is no
155 cfa37a7b 2004-04-10 devnull `click to type'.
156 cfa37a7b 2004-04-10 devnull (The experimental option
158 cfa37a7b 2004-04-10 devnull causes typing to go to the most recently clicked-at or made window.)
159 cfa37a7b 2004-04-10 devnull The usual backspacing conventions apply.
161 cfa37a7b 2004-04-10 devnull .IR sam (1)
163 cfa37a7b 2004-04-10 devnull .IR rio ,
164 cfa37a7b 2004-04-10 devnull the ESC key selects the text typed since the last mouse action,
165 cfa37a7b 2004-04-10 devnull a feature particularly useful when executing commands.
166 cfa37a7b 2004-04-10 devnull A side effect is that typing ESC with text already selected is identical
170 cfa37a7b 2004-04-10 devnull .RI ( q.v. ).
172 cfa37a7b 2004-04-10 devnull Most text, including the names of windows, may be edited uniformly.
173 cfa37a7b 2004-04-10 devnull The only exception is that the command names to the
174 cfa37a7b 2004-04-10 devnull left of the bar in a tag are maintained automatically; changes to them are repaired
176 cfa37a7b 2004-04-10 devnull .IR acme .
178 b9771a80 2005-01-30 devnull When a window is in autoindent mode
179 b9771a80 2005-01-30 devnull (see the
180 b9771a80 2005-01-30 devnull .B Indent
181 b9771a80 2005-01-30 devnull command below) and a newline character is typed,
182 b9771a80 2005-01-30 devnull acme copies leading white space on the current line to the new line.
183 b9771a80 2005-01-30 devnull The option
185 b9771a80 2005-01-30 devnull causes each window to start in
186 b9771a80 2005-01-30 devnull autoindent mode.
187 cfa37a7b 2004-04-10 devnull .SS "Directory context
188 cfa37a7b 2004-04-10 devnull Each window's tag names a directory: explicitly if the window
189 cfa37a7b 2004-04-10 devnull holds a directory; implicitly if it holds a regular file
190 cfa37a7b 2004-04-10 devnull (e.g. the directory
192 cfa37a7b 2004-04-10 devnull if the window holds
193 cfa37a7b 2004-04-10 devnull .BR /adm/users ).
194 cfa37a7b 2004-04-10 devnull This directory provides a
195 cfa37a7b 2004-04-10 devnull .I context
196 cfa37a7b 2004-04-10 devnull for interpreting file names in that window.
197 cfa37a7b 2004-04-10 devnull For example, the string
198 cfa37a7b 2004-04-10 devnull .B users
199 cfa37a7b 2004-04-10 devnull in a window labeled
200 cfa37a7b 2004-04-10 devnull .B /adm/
202 cfa37a7b 2004-04-10 devnull .B /adm/keys
203 cfa37a7b 2004-04-10 devnull will be interpreted as the file name
204 cfa37a7b 2004-04-10 devnull .BR /adm/users .
205 cfa37a7b 2004-04-10 devnull The directory is defined purely textually, so it can be a non-existent
206 cfa37a7b 2004-04-10 devnull directory or a real directory associated with a non-existent file
208 cfa37a7b 2004-04-10 devnull .BR /adm/not-a-file ).
209 cfa37a7b 2004-04-10 devnull File names beginning with a slash
210 cfa37a7b 2004-04-10 devnull are assumed to be absolute file names.

239 cfa37a7b 2004-04-10 devnull action similar to selecting text with button 1,

250 cfa37a7b 2004-04-10 devnull takes that selection as the command;
251 cfa37a7b 2004-04-10 devnull otherwise it takes the largest string of valid file name characters containing the click.
252 cfa37a7b 2004-04-10 devnull Valid file name characters are alphanumerics and
258 cfa37a7b 2004-04-10 devnull This behavior is similar to double-clicking with button 1 but,
259 cfa37a7b 2004-04-10 devnull because a null command is meaningless, only a single click is required.
