34 ;;; To see what I've modified and where it came from search for '-mm'
38 ;;; Speed considerations and a few caveats
39 ;;; --------------------------------------
41 ;;; While the message passing and the colorization surely introduce some
42 ;;; overhead this has became so small that IMHO is surely outweighted by
43 ;;; the benefits you get but, as usual, YMMV
45 ;;; Important caveat, when deciding the cursor/'grey keys' keycodes I had to
46 ;;; make a choice: on my Linux box this choice allows me to run all the
47 ;;; ncurses applications without problems but make these keys
48 ;;; uncomprehensible to all the cursesX programs. Your mileage may vary so
49 ;;; you may consider changing the default 'emulation'. Just search for this
50 ;;; piece of code and modify it as you like:
52 ;;; ;; Which would be better: "\e[A" or "\eOA"? readline accepts either.
53 ;;; ;; For my configuration it's definitely better \eOA but YMMV. -mm
54 ;;; ;; For example: vi works with \eOA while elm wants \e[A ...
55 ;;; (defun term-send-up () (interactive) (term-send-raw-string "\eOA"))
56 ;;; (defun term-send-down () (interactive) (term-send-raw-string "\eOB"))
57 ;;; (defun term-send-right () (interactive) (term-send-raw-string "\eOC"))
58 ;;; (defun term-send-left () (interactive) (term-send-raw-string "\eOD"))
61 ;;; IMPORTANT: additions & changes
62 ;;; ------------------------------
64 ;;; With this enhanced ansi-term.el you will get a reliable mechanism of
65 ;;; directory/username/host tracking: the only drawback is that you will
66 ;;; have to modify your shell start-up script. It's worth it, believe me :).
68 ;;; When you rlogin/su/telnet and the account you access has a modified
69 ;;; startup script, you will be able to access the remote files as usual
70 ;;; with C-x C-f, if it's needed you will have to enter a password,
71 ;;; otherwise the file should get loaded straight away.
73 ;;; This is useful even if you work only on one host: it often happens that,
74 ;;; for maintenance reasons, you have to edit files 'as root': before
75 ;;; patching term.el, I su-ed in a term.el buffer and used vi :), now I
76 ;;; simply do a C-x C-f and, via ange-ftp, the file is automatically loaded
77 ;;; 'as-root'. ( If you don't want to enter the root password every time you
78 ;;; can put it in your .netrc: note that this is -not- advisable if you're
79 ;;; connected to the internet or if somebody else works on your workstation!)
81 ;;; If you use wu-ftpd you can use some of its features to avoid root ftp
82 ;;; access to the rest of the world: just put in /etc/ftphosts something like
85 ;;; allow root 127.0.0.1
87 ;;; # By default nobody can't do anything
91 ;;; ----------------------------------------
93 ;;; If, instead of 'term', you call 'ansi-term', you get multiple term
94 ;;; buffers, after every new call ansi-term opens a new *ansi-term*<xx> window,
95 ;;; where <xx> is, as usual, a number...
97 ;;; ----------------------------------------
99 ;;; With the term-buffer-maximum-size you can finally decide how many
100 ;;; scrollback lines to keep: its default is 2048 but you can change it as
103 ;;; ----------------------------------------
106 ;;; ANSI colorization should work well, I've decided to limit the interpreter
107 ;;; to five outstanding commands (like ESC [ 01;04;32;41;07m.
108 ;;; You shouldn't need more, if you do, tell me and I'll increase it. It's
109 ;;; so easy you could do it yourself...
111 ;;; Blink, is not supported. Currently it's mapped as bold.
113 ;;; Important caveat:
114 ;;; -----------------
115 ;;; if you want custom colors in term.el redefine term-default-fg-color
116 ;;; and term-default-bg-color BEFORE loading it.
118 ;;; ----------------------------------------
120 ;;; If you'd like to check out my complete configuration, you can download
121 ;;; it from http://www.polito.it/~s64912/things.html, it's ~500k in size and
122 ;;; contains my .cshrc, .emacs and my whole site-lisp subdirectory. (notice
123 ;;; that this term.el may be newer/older than the one in there, please
126 ;;; This complete configuration contains, among other things, a complete
127 ;;; rectangular marking solution (based on rect-mark.el and
128 ;;; pc-bindings.el) and should be a good example of how extensively Emacs
129 ;;; can be configured on a ppp-connected ws.
131 ;;; ----------------------------------------
135 ;;; - Add hooks to allow raw-mode keys to be configurable
136 ;;; - Which keys are better ? \eOA or \e[A ?
141 ;;; V4.0 January 1997
143 ;;; - Huge reworking of the faces code: now we only have roughly 20-30
144 ;;; faces for everything so we're even faster than the old md-term.el !
145 ;;; - Finished removing all the J-Shell code.
147 ;;; V3.0 January 1997
149 ;;; - Now all the supportable ANSI commands work well.
150 ;;; - Reworked a little the code: much less jsh-inspired stuff
154 ;;; - Now all the faces are accessed through an array: much cleaner code.
156 ;;; V2.2 November 4 1996
158 ;;; - Implemented ANSI output colorization ( a bit rough but enough for
161 ;;; - Implemented a maximum limit for the scroll buffer (stolen from
164 ;;; v2.1 October 28 1996, first public release
166 ;;; - Some new keybindings for term-char mode ( notably home/end/...)
167 ;;; - Directory, hostname and username tracking via ange-ftp
168 ;;; - Multi-term capability via the ansi-term call
170 ;;; ----------------------------------------------------------------
171 ;;; You should/could have something like this in your .emacs to take
172 ;;; full advantage of this package
174 ;;; (add-hook 'term-mode-hook
177 ;;; (setq term-prompt-regexp "^[^#$%>\n]*[#$%>] *")

188 ;;; If you want to use color ls the best setup is to have a different file
189 ;;; when you use eterm ( see above, mine is named .emacs_dircolors ). This
190 ;;; is necessary because some terminals, rxvt for example, need non-ansi
191 ;;; hacks to work ( for example on my rxvt white is wired to fg, and to
192 ;;; obtain normal white I have to do bold-white :)

346 ;; - Per Bothner (bothner@cygnus.com)
348 ;; This file defines a general command-interpreter-in-a-buffer package
349 ;; (term mode). The idea is that you can build specific process-in-a-buffer
350 ;; modes on top of term mode -- e.g., lisp, shell, scheme, T, soar, ....
351 ;; This way, all these specific packages share a common base functionality,
352 ;; and a common set of bindings, which makes them easier to use (and
353 ;; saves code, implementation time, etc., etc.).
355 ;; For hints on converting existing process modes (e.g., tex-mode,
356 ;; background, dbx, gdb, kermit, prolog, telnet) to use term-mode
357 ;; instead of shell-mode, see the notes at the end of this file.

962 "Major mode for interacting with an inferior interpreter.
963 The interpreter name is same as buffer name, sans the asterisks.
965 There are two submodes: line mode and char mode. By default, you are
966 in char mode. In char sub-mode, each character (except
967 `term-escape-char') is sent immediately to the subprocess.
968 The escape character is equivalent to the usual meaning of C-x.
970 In line mode, you send a line of input at a time; use
971 \\[term-send-input] to send.
973 In line mode, this maintains an input history of size
974 `term-input-ring-size', and you can access it with the commands
975 \\[term-next-input], \\[term-previous-input], and
976 \\[term-dynamic-list-input-ring]. Input ring history expansion can be
977 achieved with the commands \\[term-replace-by-expanded-history] or
978 \\[term-magic-space]. Input ring expansion is controlled by the
979 variable `term-input-autoexpand', and addition is controlled by the
980 variable `term-input-ignoredups'.
982 Input to, and output from, the subprocess can cause the window to scroll to
983 the end of the buffer. See variables `term-scroll-to-bottom-on-input',
984 and `term-scroll-to-bottom-on-output'.
986 If you accidentally suspend your process, use \\[term-continue-subjob]
989 This mode can be customized to create specific modes for running
990 particular subprocesses. This can be done by setting the hooks
991 `term-input-filter-functions', `term-input-filter',
992 `term-input-sender' and `term-get-old-input' to appropriate functions,
993 and the variable `term-prompt-regexp' to the appropriate regular

2335 ;;; files). So the corresponding process-in-a-buffer modes have commands
2336 ;;; for doing this (e.g., lisp-load-file). The functions below are useful
2337 ;;; for defining these commands.
2339 ;;; Alas, these guys don't do exactly the right thing for Lisp, Scheme
2340 ;;; and Soar, in that they don't know anything about file extensions.
2341 ;;; So the compile/load interface gets the wrong default occasionally.
2342 ;;; The load-file/compile-file default mechanism could be smarter -- it
2343 ;;; doesn't know about the relationship between filename extensions and
2344 ;;; whether the file is source or executable. If you compile foo.lisp
2345 ;;; with compile-file, then the next load-file should use foo.bin for
2346 ;;; the default, not foo.lisp. This is tricky to do right, particularly
2347 ;;; because the extension for executable files varies so much (.o, .bin,
2348 ;;; .lbin, .mo, .vo, .ao, ...).
