32 | ;;; This file defines a general command-interpreter-in-a-buffer package |
33 | ;;; (comint mode). The idea is that you can build specific process-in-a-buffer | |
34 | ;;; modes on top of comint mode -- e.g., lisp, shell, scheme, T, soar, .... | |
35 | ;;; This way, all these specific packages share a common base functionality, | |
36 | ;;; and a common set of bindings, which makes them easier to use (and | |
37 | ;;; saves code, implementation time, etc., etc.). | |
38 | ||
49116ac0 | 39 | ;;; Several packages are already defined using comint mode: |
735b3061 | 40 | ;;; - shell.el defines a shell-in-a-buffer mode. |
49116ac0 | 41 | ;;; - cmulisp.el defines a simple lisp-in-a-buffer mode. |
49116ac0 JB |
42 | ;;; |
43 | ;;; - The file cmuscheme.el defines a scheme-in-a-buffer mode. | |
44 | ;;; - The file tea.el tunes scheme and inferior-scheme modes for T. | |
45 | ;;; - The file soar.el tunes lisp and inferior-lisp modes for Soar. | |
46 | ;;; - cmutex.el defines tex and latex modes that invoke tex, latex, bibtex, | |
47 | ;;; previewers, and printers from within emacs. | |
48 | ;;; - background.el allows csh-like job control inside emacs. | |
49 | ;;; It is pretty easy to make new derived modes for other processes. | |
50 | ||
be9b65ac DL |
51 | ;;; For documentation on the functionality provided by comint mode, and |
52 | ;;; the hooks available for customising it, see the comments below. | |
53 | ;;; For further information on the standard derived modes (shell, | |
54 | ;;; inferior-lisp, inferior-scheme, ...), see the relevant source files. | |
55 | ||
49116ac0 JB |
56 | ;;; For hints on converting existing process modes (e.g., tex-mode, |
57 | ;;; background, dbx, gdb, kermit, prolog, telnet) to use comint-mode | |
be9b65ac DL |
58 | ;;; instead of shell-mode, see the notes at the end of this file. |

827 | ;;;============================================================================ | |
828 | ;;; Many command-interpreters (e.g., Lisp, Scheme, Soar) have | |
829 | ;;; commands that process files of source text (e.g. loading or compiling | |
830 | ;;; files). So the corresponding process-in-a-buffer modes have commands | |
831 | ;;; for doing this (e.g., lisp-load-file). The functions below are useful | |
832 | ;;; for defining these commands. | |
833 | ;;; | |
834 | ;;; Alas, these guys don't do exactly the right thing for Lisp, Scheme | |
835 | ;;; and Soar, in that they don't know anything about file extensions. | |
836 | ;;; So the compile/load interface gets the wrong default occasionally. | |
837 | ;;; The load-file/compile-file default mechanism could be smarter -- it | |
838 | ;;; doesn't know about the relationship between filename extensions and | |
839 | ;;; whether the file is source or executable. If you compile foo.lisp | |
840 | ;;; with compile-file, then the next load-file should use foo.bin for | |
841 | ;;; the default, not foo.lisp. This is tricky to do right, particularly | |
842 | ;;; because the extension for executable files varies so much (.o, .bin, | |
843 | ;;; .lbin, .mo, .vo, .ao, ...). | |

1117 | ;;; Converting process modes to use comint mode | |
1118 | ;;; =========================================================================== | |
be14d312 ER |
1119 | ;;; The code in the Emacs 19 distribution has all been modified to use comint |
1120 | ;;; where needed. However, there are `third-party' packages out there that | |
1121 | ;;; still use the old shell mode. Here's a guide to conversion. | |

be9b65ac | 1123 | ;;; Renaming variables |
49116ac0 JB |

be9b65ac DL |
1132 | ;;; shell-set-directory <unnecessary> |
1133 | ;;; shell-mode-map comint-mode-map | |
49116ac0 | 1134 | ;;; Commands: |

1135 | ;;; shell-send-input comint-send-input |
1136 | ;;; shell-send-eof comint-delchar-or-maybe-eof | |

1145 | ;;; | |
87ef29fd JB |
1146 | ;;; SHELL-SET-DIRECTORY is gone, its functionality taken over by |
1147 | ;;; SHELL-DIRECTORY-TRACKER, the shell mode's comint-input-sentinel. | |
1148 | ;;; Comint mode does not provide functionality equivalent to | |
be9b65ac | 1149 | ;;; shell-set-directory-error-hook; it is gone. |
87ef29fd JB |
1150 | ;;; |
1151 | ;;; comint-last-input-start is provided for modes which want to munge | |
1152 | ;;; the buffer after input is sent, perhaps because the inferior | |
1153 | ;;; insists on echoing the input. The LAST-INPUT-START variable in | |
1154 | ;;; the old shell package was used to implement a history mechanism, | |
1155 | ;;; but you should think twice before using comint-last-input-start | |
1156 | ;;; for this; the input history ring often does the job better. | |
be9b65ac DL |
1157 | ;;; |
1158 | ;;; If you are implementing some process-in-a-buffer mode, called foo-mode, do | |
1159 | ;;; *not* create the comint-mode local variables in your foo-mode function. | |
1160 | ;;; This is not modular. Instead, call comint-mode, and let *it* create the | |
1161 | ;;; necessary comint-specific local variables. Then create the | |
1162 | ;;; foo-mode-specific local variables in foo-mode. Set the buffer's keymap to | |
1163 | ;;; be foo-mode-map, and its mode to be foo-mode. Set the comint-mode hooks | |
1164 | ;;; (comint-prompt-regexp, comint-input-filter, comint-input-sentinel, | |
1165 | ;;; comint-get-old-input) that need to be different from the defaults. Call | |
1166 | ;;; foo-mode-hook, and you're done. Don't run the comint-mode hook yourself; | |
735b3061 | 1167 | ;;; comint-mode will take care of it. The following example, from shell.el, |

1203 | ;;; Change log: | |
1204 | ;;; 9/12/89 | |
1205 | ;;; - Souped up the filename expansion procedures. | |
1206 | ;;; Doc strings are much clearer and more detailed. | |
1207 | ;;; Fixed a bug where doing a filename completion when the point | |
1208 | ;;; was in the middle of the filename instead of at the end would lose. | |
1209 | ;;; | |
1210 | ;;; 2/17/90 | |
1211 | ;;; - Souped up the command history stuff so that text inserted | |
1212 | ;;; by comint-previous-input-matching is removed by following | |
1213 | ;;; command history recalls. comint-next/previous-input-matching | |
1214 | ;;; is now much more smoothly integrated w/the command history stuff. | |
1215 | ;;; - Added comint-eol-on-send flag and comint-input-sender hook. | |
1216 | ;;; Comint-input-sender based on code contributed by Jeff Peck | |
1217 | ;;; (peck@sun.com). | |
1218 | ;;; | |
1219 | ;;; 3/13/90 ccm@cmu.cs.edu | |
1220 | ;;; - Added comint-previous-similar-input for looking up similar inputs. | |
1221 | ;;; - Added comint-send-and-get-output to allow snarfing input from | |
1222 | ;;; buffer. | |
1223 | ;;; - Added the ability to pick up a source file by positioning over | |
1224 | ;;; a string in comint-get-source. | |
1225 | ;;; - Added add-hook to make it a little easier for the user to use | |
1226 | ;;; multiple hooks. | |
1227 | ;;; | |
1228 | ;;; 5/22/90 shivers | |
1229 | ;;; - Moved Chris' multiplexed ipc stuff to comint-ipc.el. | |
1230 | ;;; - Altered Chris' comint-get-source string feature. The string | |
1231 | ;;; is only offered as a default if it names an existing file. | |
1232 | ;;; - Changed comint-exec to directly crank up the process, instead | |
1233 | ;;; of calling the env program. This made background.el happy. | |
1234 | ;;; - Added new buffer-local var comint-ptyp. The problem is that | |
1235 | ;;; the signalling functions don't work as advertised. If you are | |
1236 | ;;; communicating via pipes, the CURRENT-GROUP arg is supposed to | |
1237 | ;;; be ignored, but, unfortunately it seems to be the case that you | |
1238 | ;;; must pass a NIL for this arg in the pipe case. COMINT-PTYP | |
1239 | ;;; is a flag that tells whether the process is communicating | |
1240 | ;;; via pipes or a pty. The comint signalling functions use it | |
1241 | ;;; to determine the necessary CURRENT-GROUP arg value. The bug | |
1242 | ;;; has been reported to the Gnu folks. | |
1243 | ;;; - comint-dynamic-complete flushes the help window if you hit space | |
1244 | ;;; after you execute it. | |
1245 | ;;; - Added functions comint-send-string, comint-send-region and var | |
1246 | ;;; comint-input-chunk-size. comint-send-string tries to prevent processes | |
1247 | ;;; from hanging when you send them long strings by breaking them into | |
1248 | ;;; chunks and allowing process output between chunks. I got the idea from | |
1249 | ;;; Eero Simoncelli's Common Lisp package. Note that using | |
1250 | ;;; comint-send-string means that the process buffer's contents can change | |
1251 | ;;; during a call! If you depend on process output only happening between | |
1252 | ;;; toplevel commands, this could be a problem. In such a case, use | |
1253 | ;;; process-send-string instead. If this is a problem for people, I'd like | |
1254 | ;;; to hear about it. | |
1255 | ;;; - Added comint-proc-query as a simple mechanism for commands that | |
1256 | ;;; want to query an inferior process and display its response. For a | |
1257 | ;;; typical use, see lisp-show-arglist in cmulisp.el. | |
1258 | ;;; - Added constant comint-version, which is now "2.01". | |
1259 | ;;; | |
1260 | ;;; 6/14/90 shivers | |
1261 | ;;; - Had comint-update-env defined twice. Removed extra copy. Also | |
1262 | ;;; renamed mem to be comint-mem, for modularity. The duplication | |
1263 | ;;; was reported by Michael Meissner. | |
1264 | ;;; 6/16/90 shivers | |
1265 | ;;; - Emacs has two different mechanisms for maintaining the process | |
1266 | ;;; environment, determined at compile time by the MAINTAIN-ENVIRONMENT | |
1267 | ;;; #define. One uses the process-environment global variable, and | |
1268 | ;;; one uses a getenv/setenv interface. comint-exec assumed the | |
1269 | ;;; process-environment interface; it has been generalised (with | |
1270 | ;;; comint-exec-1) to handle both cases. Pretty bogus. We could, | |
1271 | ;;; of course, skip all this and just use the etc/env program to | |
1272 | ;;; handle the environment tweaking, but that obscures process | |
1273 | ;;; queries that other modules (like background.el) depend on. etc/env | |
1274 | ;;; is also fairly bogus. This bug, and some of the fix code was | |
1275 | ;;; reported by Dan Pierson. | |
1276 | ;;; | |
1277 | ;;; 9/5/90 shivers | |
1278 | ;;; - Changed make-variable-buffer-local's to make-local-variable's. | |
1279 | ;;; This leaves non-comint-mode buffers alone. Stephane Payrard | |
1280 | ;;; reported the sloppy useage. | |
1281 | ;;; - You can now go from comint-previous-similar-input to | |
1282 | ;;; comint-previous-input with no problem. | |
1283 | ;;; | |
1284 | ;;; 12/21/90 shivers | |
1285 | ;;; - Added a condition-case to comint-get-source. Bogus strings | |
1286 | ;;; beginning with ~ were making the file-exists-p barf. | |
1287 | ;;; - Added "=" to the set of chars recognised by file completion | |
1288 | ;;; as constituting a filename. | |
1289 | ;;; | |
1290 | ;;; 1/90 shivers | |
1291 | ;;; These changes comprise release 2.02: | |
1292 | ;;; - Removed the kill-all-local-variables in comint-mode. This | |
1293 | ;;; made it impossible for client modes to set things before calling | |
1294 | ;;; comint-mode. (In particular, it messed up ilisp.el) In general, | |
1295 | ;;; the client mode should be responsible for a k-a-l-v's. | |
1296 | ;;; - Fixed comint-match-partial-pathname so that it works in | |
1297 | ;;; more cases: if the filename begins at the start-of-buffer; | |
1298 | ;;; if point is on the first char of the filename. Just a question | |
1299 | ;;; of getting the tricky bits right. | |
1300 | ;;; - Added a hook, comint-exec-hook that is run each time a process | |
1301 | ;;; is cranked up. Useful for things like process-kill-without-query. | |
1302 | ;;; | |
87ef29fd | 1303 | ;;; These two were pointed out by tale: |
49116ac0 JB |
1304 | ;;; - Improved the doc string in comint-send-input a little bit. |
1305 | ;;; - Tweaked make-comint to check process status with comint-check-proc | |
1306 | ;;; instead of equivalent inline code. | |
87ef29fd | 1307 | ;;; |
49116ac0 JB |
1308 | ;;; - Prompt-search history commands have been commented out. I never |
1309 | ;;; liked them; I don't think anyone used them. | |
87ef29fd | 1310 | ;;; - Made comint-exec-hook a local var, as it should have been. |
735b3061 | 1311 | ;;; (This way, for instance, you can have shell procs kill-w/o-query, |
87ef29fd JB |
1312 | ;;; but let Scheme procs be default.) |
1313 | ;;; | |
1314 | ;;; 7/91 Shivers | |
1315 | ;;; - Souped up comint-read-noecho with an optional argument, STARS. | |
1316 | ;;; Suggested by mjlx@EAGLE.CNSF.CORNELL.EDU. | |
1317 | ;;; - Moved comint-previous-input-matching from C-c r to C-M-r. | |
1318 | ;;; C-c <letter> bindings are reserved for the user. | |
1319 | ;;; These bindings were done by Jim Blandy. | |
1320 | ;;; These changes comprise version 2.03. | |
