37 | ;; Speed considerations and a few caveats |
38 | ;; -------------------------------------- | |
39 | ;; | |
40 | ;; While the message passing and the colorization surely introduce some | |
41 | ;; overhead this has became so small that IMHO is surely outweighted by | |
42 | ;; the benefits you get but, as usual, YMMV | |
43 | ;; | |
44 | ;; Important caveat, when deciding the cursor/'grey keys' keycodes I had to | |
45 | ;; make a choice: on my Linux box this choice allows me to run all the | |
46 | ;; ncurses applications without problems but make these keys | |
47 | ;; uncomprehensible to all the cursesX programs. Your mileage may vary so | |
48 | ;; you may consider changing the default 'emulation'. Just search for this | |
49 | ;; piece of code and modify it as you like: | |
50 | ;; | |
51 | ;; ;; Which would be better: "\e[A" or "\eOA"? readline accepts either. | |
52 | ;; ;; For my configuration it's definitely better \eOA but YMMV. -mm | |
53 | ;; ;; For example: vi works with \eOA while elm wants \e[A ... | |
54 | ;; (defun term-send-up () (interactive) (term-send-raw-string "\eOA")) | |
55 | ;; (defun term-send-down () (interactive) (term-send-raw-string "\eOB")) | |
56 | ;; (defun term-send-right () (interactive) (term-send-raw-string "\eOC")) | |
57 | ;; (defun term-send-left () (interactive) (term-send-raw-string "\eOD")) | |
58 | ;; | |
59 | ;; | |
60 | ;; IMPORTANT: additions & changes | |
61 | ;; ------------------------------ | |
62 | ;; | |
63 | ;; With this enhanced ansi-term.el you will get a reliable mechanism of | |
64 | ;; directory/username/host tracking: the only drawback is that you will | |
65 | ;; have to modify your shell start-up script. It's worth it, believe me :). | |
66 | ;; | |
67 | ;; When you rlogin/su/telnet and the account you access has a modified | |
68 | ;; startup script, you will be able to access the remote files as usual | |
69 | ;; with C-x C-f, if it's needed you will have to enter a password, | |
70 | ;; otherwise the file should get loaded straight away. | |
71 | ;; | |
72 | ;; This is useful even if you work only on one host: it often happens that, | |
73 | ;; for maintenance reasons, you have to edit files 'as root': before | |
74 | ;; patching term.el, I su-ed in a term.el buffer and used vi :), now I | |
75 | ;; simply do a C-x C-f and, via ange-ftp, the file is automatically loaded | |
76 | ;; 'as-root'. ( If you don't want to enter the root password every time you | |
77 | ;; can put it in your .netrc: note that this is -not- advisable if you're | |
78 | ;; connected to the internet or if somebody else works on your workstation!) | |
79 | ;; | |
80 | ;; If you use wu-ftpd you can use some of its features to avoid root ftp | |
81 | ;; access to the rest of the world: just put in /etc/ftphosts something like | |
82 | ;; | |
83 | ;; # Local access | |
84 | ;; allow root 127.0.0.1 | |
85 | ;; | |
86 | ;; # By default nobody can't do anything | |
87 | ;; deny root * | |
88 | ;; | |
89 | ;; | |
90 | ;; ---------------------------------------- | |
91 | ;; | |
92 | ;; If, instead of 'term', you call 'ansi-term', you get multiple term | |
93 | ;; buffers, after every new call ansi-term opens a new *ansi-term*<xx> window, | |
94 | ;; where <xx> is, as usual, a number... | |
95 | ;; | |
96 | ;; ---------------------------------------- | |
97 | ;; | |
98 | ;; With the term-buffer-maximum-size you can finally decide how many | |
99 | ;; scrollback lines to keep: its default is 2048 but you can change it as | |
100 | ;; usual. | |
101 | ;; | |
102 | ;; ---------------------------------------- | |
103 | ;; | |
104 | ;; | |
105 | ;; ANSI colorization should work well, I've decided to limit the interpreter | |
106 | ;; to five outstanding commands (like ESC [ 01;04;32;41;07m. | |
107 | ;; You shouldn't need more, if you do, tell me and I'll increase it. It's | |
108 | ;; so easy you could do it yourself... | |
109 | ;; | |
110 | ;; Blink, is not supported. Currently it's mapped as bold. | |
111 | ;; | |
112 | ;; Important caveat: | |
113 | ;; ----------------- | |
114 | ;; if you want custom colors in term.el redefine term-default-fg-color | |
115 | ;; and term-default-bg-color BEFORE loading it. | |
116 | ;; | |
117 | ;; ---------------------------------------- | |
118 | ;; | |
119 | ;; If you'd like to check out my complete configuration, you can download | |
120 | ;; it from http://www.polito.it/~s64912/things.html, it's ~500k in size and | |
121 | ;; contains my .cshrc, .emacs and my whole site-lisp subdirectory. (notice | |
122 | ;; that this term.el may be newer/older than the one in there, please | |
123 | ;; check!) | |
124 | ;; | |
125 | ;; This complete configuration contains, among other things, a complete | |
126 | ;; rectangular marking solution (based on rect-mark.el and | |
127 | ;; pc-bindings.el) and should be a good example of how extensively Emacs | |
128 | ;; can be configured on a ppp-connected ws. | |
129 | ;; | |

131 | ;; | |
132 | ;; TODO: | |
133 | ;; | |
134 | ;; - Add hooks to allow raw-mode keys to be configurable | |
135 | ;; - Which keys are better ? \eOA or \e[A ? | |
136 | ;; | |
137 | ;; | |
138 | ;; Changes: | |
139 | ;; | |
140 | ;; V4.0 January 1997 | |
141 | ;; | |
142 | ;; - Huge reworking of the faces code: now we only have roughly 20-30 | |
143 | ;; faces for everything so we're even faster than the old md-term.el ! | |
144 | ;; - Finished removing all the J-Shell code. | |
145 | ;; | |
146 | ;; V3.0 January 1997 | |
147 | ;; | |
148 | ;; - Now all the supportable ANSI commands work well. | |
149 | ;; - Reworked a little the code: much less jsh-inspired stuff | |
150 | ;; | |
151 | ;; V2.3 November | |
152 | ;; | |
153 | ;; - Now all the faces are accessed through an array: much cleaner code. | |
154 | ;; | |
155 | ;; V2.2 November 4 1996 | |
156 | ;; | |
157 | ;; - Implemented ANSI output colorization ( a bit rough but enough for | |
158 | ;; color_ls ) | |
159 | ;; | |
160 | ;; - Implemented a maximum limit for the scroll buffer (stolen from | |
161 | ;; comint.el) | |
162 | ;; | |
163 | ;; v2.1 October 28 1996, first public release | |
164 | ;; | |
165 | ;; - Some new keybindings for term-char mode ( notably home/end/...) | |
166 | ;; - Directory, hostname and username tracking via ange-ftp | |
167 | ;; - Multi-term capability via the ansi-term call | |
168 | ;; | |
169 | ;; ---------------------------------------------------------------- | |
170 | ;; You should/could have something like this in your .emacs to take | |
171 | ;; full advantage of this package | |
172 | ;; | |
173 | ;; (add-hook 'term-mode-hook | |
174 | ;; (function | |
175 | ;; (lambda () | |
176 | ;; (setq term-prompt-regexp "^[^#$%>\n]*[#$%>] *") | |
177 | ;; (make-local-variable 'mouse-yank-at-point) | |
178 | ;; (make-local-variable 'transient-mark-mode) | |
179 | ;; (setq mouse-yank-at-point t) | |
180 | ;; (setq transient-mark-mode nil) | |
181 | ;; (auto-fill-mode -1) | |
182 | ;; (setq tab-width 8 )))) | |
183 | ;; | |
184 | ;; | |
185 | ;; ---------------------------------------- | |
186 | ;; | |
187 | ;; If you want to use color ls the best setup is to have a different file | |
188 | ;; when you use eterm ( see above, mine is named .emacs_dircolors ). This | |
189 | ;; is necessary because some terminals, rxvt for example, need non-ansi | |
190 | ;; hacks to work ( for example on my rxvt white is wired to fg, and to | |
191 | ;; obtain normal white I have to do bold-white :) | |

986 | The interpreter name is same as buffer name, sans the asterisks. | |
987 | ||
988 | There are two submodes: line mode and char mode. By default, you are | |
989 | in char mode. In char sub-mode, each character (except | |
269cb13e RS |
990 | `term-escape-char') is sent immediately to the subprocess. |
991 | The escape character is equivalent to the usual meaning of C-x. | |
c2f0944a RS |
992 | |
993 | In line mode, you send a line of input at a time; use | |
994 | \\[term-send-input] to send. | |
995 | ||
996 | In line mode, this maintains an input history of size | |
997 | `term-input-ring-size', and you can access it with the commands | |
998 | \\[term-next-input], \\[term-previous-input], and | |
999 | \\[term-dynamic-list-input-ring]. Input ring history expansion can be | |
1000 | achieved with the commands \\[term-replace-by-expanded-history] or | |
1001 | \\[term-magic-space]. Input ring expansion is controlled by the | |
1002 | variable `term-input-autoexpand', and addition is controlled by the | |
1003 | variable `term-input-ignoredups'. | |
1004 | ||
1005 | Input to, and output from, the subprocess can cause the window to scroll to | |
1006 | the end of the buffer. See variables `term-scroll-to-bottom-on-input', | |
1007 | and `term-scroll-to-bottom-on-output'. | |
1008 | ||
1009 | If you accidentally suspend your process, use \\[term-continue-subjob] | |
1010 | to continue it. | |
1011 | ||
14629f15 | 1012 | This mode can be customized to create specific modes for running |
c2f0944a RS |
1013 | particular subprocesses. This can be done by setting the hooks |
1014 | `term-input-filter-functions', `term-input-filter', | |
1015 | `term-input-sender' and `term-get-old-input' to appropriate functions, | |

4450 | ;; Most of the work is renaming variables and functions. These are the common | |
4451 | ;; ones: | |
4452 | ;; Local variables: | |
4453 | ;; last-input-start term-last-input-start | |
4454 | ;; last-input-end term-last-input-end | |
4455 | ;; shell-prompt-pattern term-prompt-regexp | |
4456 | ;; shell-set-directory-error-hook <no equivalent> | |
4457 | ;; Miscellaneous: | |
4458 | ;; shell-set-directory <unnecessary> | |
4459 | ;; shell-mode-map term-mode-map | |
4460 | ;; Commands: | |
4461 | ;; shell-send-input term-send-input | |
4462 | ;; shell-send-eof term-delchar-or-maybe-eof | |
4463 | ;; kill-shell-input term-kill-input | |
4464 | ;; interrupt-shell-subjob term-interrupt-subjob | |
4465 | ;; stop-shell-subjob term-stop-subjob | |
4466 | ;; quit-shell-subjob term-quit-subjob | |
4467 | ;; kill-shell-subjob term-kill-subjob | |
4468 | ;; kill-output-from-shell term-kill-output | |
4469 | ;; show-output-from-shell term-show-output | |
4470 | ;; copy-last-shell-input Use term-previous-input/term-next-input | |
4471 | ;; | |
4472 | ;; SHELL-SET-DIRECTORY is gone, its functionality taken over by | |
4473 | ;; SHELL-DIRECTORY-TRACKER, the shell mode's term-input-filter-functions. | |
4474 | ;; Term mode does not provide functionality equivalent to | |
4475 | ;; shell-set-directory-error-hook; it is gone. | |
4476 | ;; | |
4477 | ;; term-last-input-start is provided for modes which want to munge | |
4478 | ;; the buffer after input is sent, perhaps because the inferior | |
4479 | ;; insists on echoing the input. The LAST-INPUT-START variable in | |
4480 | ;; the old shell package was used to implement a history mechanism, | |
4481 | ;; but you should think twice before using term-last-input-start | |
4482 | ;; for this; the input history ring often does the job better. | |
4483 | ;; | |
4484 | ;; If you are implementing some process-in-a-buffer mode, called foo-mode, do | |
4485 | ;; *not* create the term-mode local variables in your foo-mode function. | |
4486 | ;; This is not modular. Instead, call term-mode, and let *it* create the | |
4487 | ;; necessary term-specific local variables. Then create the | |
4488 | ;; foo-mode-specific local variables in foo-mode. Set the buffer's keymap to | |
4489 | ;; be foo-mode-map, and its mode to be foo-mode. Set the term-mode hooks | |
4490 | ;; (term-{prompt-regexp, input-filter, input-filter-functions, | |
4491 | ;; get-old-input) that need to be different from the defaults. Call | |
4492 | ;; foo-mode-hook, and you're done. Don't run the term-mode hook yourself; | |
4493 | ;; term-mode will take care of it. The following example, from shell.el, | |
4494 | ;; is typical: | |
4495 | ;; | |
4496 | ;; (defvar shell-mode-map '()) | |
