28 | ;;; Commentary: |
29 | ||
b578f267 | 30 | ;; This file defines a general command-interpreter-in-a-buffer package |
f4e432bb SM |
31 | ;; (comint mode). The idea is that you can build specific process-in-a-buffer |
32 | ;; modes on top of comint mode -- e.g., Lisp, shell, scheme, T, soar, .... | |
814299a7 | 33 | ;; This way, all these specific packages share a common base functionality, |
b578f267 EN |
34 | ;; and a common set of bindings, which makes them easier to use (and |
35 | ;; saves code, implementation time, etc., etc.). | |
36 | ||
37 | ;; Several packages are already defined using comint mode: | |
38 | ;; - shell.el defines a shell-in-a-buffer mode. | |
39 | ;; - cmulisp.el defines a simple lisp-in-a-buffer mode. | |
40 | ;; | |
41 | ;; - The file cmuscheme.el defines a scheme-in-a-buffer mode. | |
42 | ;; - The file tea.el tunes scheme and inferior-scheme modes for T. | |
f4e432bb SM |
43 | ;; - The file soar.el tunes Lisp and inferior-lisp modes for Soar. |
44 | ;; - cmutex.el defines TeX and LaTeX modes that invoke TeX, LaTeX, BibTeX, | |
45 | ;; previewers, and printers from within Emacs. | |
46 | ;; - background.el allows csh-like job control inside Emacs. | |
b578f267 EN |
47 | ;; It is pretty easy to make new derived modes for other processes. |
48 | ||
f4e432bb | 49 | ;; For documentation on the functionality provided by Comint mode, and |
b578f267 | 50 | ;; the hooks available for customising it, see the comments below. |
814299a7 | 51 | ;; For further information on the standard derived modes (shell, |
b578f267 EN |
52 | ;; inferior-lisp, inferior-scheme, ...), see the relevant source files. |
53 | ||
54 | ;; For hints on converting existing process modes (e.g., tex-mode, | |
55 | ;; background, dbx, gdb, kermit, prolog, telnet) to use comint-mode | |
56 | ;; instead of shell-mode, see the notes at the end of this file. | |

2370 | ;; Support for source-file processing commands. |
2371 | ;;============================================================================ | |
2372 | ;; Many command-interpreters (e.g., Lisp, Scheme, Soar) have | |
2373 | ;; commands that process files of source text (e.g. loading or compiling | |
0ff9b955 PJ |
2374 | ;; files). So the corresponding process-in-a-buffer modes have commands |
2375 | ;; for doing this (e.g., lisp-load-file). The functions below are useful | |
b578f267 EN |
2376 | ;; for defining these commands. |
2377 | ;; | |
2378 | ;; Alas, these guys don't do exactly the right thing for Lisp, Scheme | |
2379 | ;; and Soar, in that they don't know anything about file extensions. | |
2380 | ;; So the compile/load interface gets the wrong default occasionally. | |
2381 | ;; The load-file/compile-file default mechanism could be smarter -- it | |
2382 | ;; doesn't know about the relationship between filename extensions and | |
0ff9b955 | 2383 | ;; whether the file is source or executable. If you compile foo.lisp |
b578f267 | 2384 | ;; with compile-file, then the next load-file should use foo.bin for |
0ff9b955 | 2385 | ;; the default, not foo.lisp. This is tricky to do right, particularly |
b578f267 EN |
2386 | ;; because the extension for executable files varies so much (.o, .bin, |
2387 | ;; .lbin, .mo, .vo, .ao, ...). | |

f4e432bb SM |
2405 | SOURCE-MODES is a list used to determine what buffers contain source |
2406 | files: if the major mode of the buffer is in SOURCE-MODES, it's source. | |
2407 | Typically, (lisp-mode) or (scheme-mode). | |
2408 | ||
2409 | If the command is given while the cursor is inside a string, *and* | |
2410 | the string is an existing filename, *and* the filename is not a directory, | |
2411 | then the string is taken as default. This allows you to just position | |
2412 | your cursor over a string that's a filename and have it taken as default. | |
2413 | ||
2414 | If the command is given in a file buffer whose major mode is in | |
2415 | SOURCE-MODES, then the filename is the default file, and the | |
2416 | file's directory is the default directory. | |
2417 | ||
2418 | If the buffer isn't a source file buffer (e.g., it's the process buffer), | |
2419 | then the default directory & file are what was used in the last source-file | |
2420 | processing command (i.e., PREVIOUS-DIR/FILE). If this is the first time | |
2421 | the command has been run (PREVIOUS-DIR/FILE is nil), the default directory | |
2422 | is the cwd, with no default file. (\"no default file\" = nil) | |
2423 | ||
d6ff789c | 2424 | SOURCE-MODES is typically going to be something like (tea-mode) |

814299a7 | 3017 | ;; |

3018 | ;; My particular use is SQL interpreters; I want to be able to execute a |
3019 | ;; query using the process associated with a comint-buffer, and save that | |
f4e432bb | 3020 | ;; somewhere else. Because the process might have state (for example, it |
3965beb0 GM |
3021 | ;; could be in an uncommitted transaction), just running starting a new |
3022 | ;; process and having it execute the query and then finish, would not | |
f4e432bb | 3023 | ;; work. I'm sure there are other uses as well, although in many cases |
3965beb0 | 3024 | ;; starting a new process is the simpler, and thus preferable, approach. |
814299a7 | 3025 | ;; |
3965beb0 | 3026 | ;; The basic implementation is as follows: comint-redirect changes the |
f4e432bb SM |
3027 | ;; preoutput filter functions (`comint-preoutput-filter-functions') to use |
3028 | ;; its own filter. The filter puts the output into the designated buffer, | |
3965beb0 | 3029 | ;; or buffers, until it sees a regexp that tells it to stop (by default, |
f4e432bb | 3030 | ;; this is the prompt for the interpreter, `comint-prompt-regexp'). When it |
3965beb0 | 3031 | ;; sees the stop regexp, it restores the old filter functions, and runs |
f4e432bb | 3032 | ;; `comint-redirect-hook'. |
3965beb0 GM |
3033 | ;; |
3034 | ;; Each comint buffer may only use one redirection at a time, but any number | |
3035 | ;; of different comint buffers may be simultaneously redirected. | |
3036 | ;; | |
3037 | ;; NOTE: It is EXTREMELY important that `comint-prompt-regexp' be set to the | |
3038 | ;; correct prompt for your interpreter, or that you supply a regexp that says | |
f4e432bb SM |
3039 | ;; when the redirection is finished. Otherwise, redirection will continue |
3040 | ;; indefinitely. The code now does a sanity check to ensure that it can find | |
3965beb0 GM |
3041 | ;; a prompt in the comint buffer; however, it is still important to ensure that |
3042 | ;; this prompt is set correctly. | |
