36 | ;;; Speed considerations and a few caveats |
37 | ;;; -------------------------------------- | |
38 | ;;; | |
39 | ;;; While the message passing and the colorization surely introduce some | |
40 | ;;; overhead this has became so small that IMHO is surely outweighted by | |
41 | ;;; the benefits you get but, as usual, YMMV | |
42 | ;;; | |
43 | ;;; Important caveat, when deciding the cursor/'grey keys' keycodes I had to | |
44 | ;;; make a choice: on my Linux box this choice allows me to run all the | |
45 | ;;; ncurses applications without problems but make these keys | |
46 | ;;; uncomprehensible to all the cursesX programs. Your mileage may vary so | |
47 | ;;; you may consider changing the default 'emulation'. Just search for this | |
48 | ;;; piece of code and modify it as you like: | |
49 | ;;; | |
50 | ;;; ;; Which would be better: "\e[A" or "\eOA"? readline accepts either. | |
51 | ;;; ;; For my configuration it's definitely better \eOA but YMMV. -mm | |
52 | ;;; ;; For example: vi works with \eOA while elm wants \e[A ... | |
53 | ;;; (defun term-send-up () (interactive) (term-send-raw-string "\eOA")) | |
54 | ;;; (defun term-send-down () (interactive) (term-send-raw-string "\eOB")) | |
55 | ;;; (defun term-send-right () (interactive) (term-send-raw-string "\eOC")) | |
56 | ;;; (defun term-send-left () (interactive) (term-send-raw-string "\eOD")) | |
57 | ;;; | |
58 | ;;; | |
59 | ;;; IMPORTANT: additions & changes | |
60 | ;;; ------------------------------ | |
61 | ;;; | |
62 | ;;; With this enhanced ansi-term.el you will get a reliable mechanism of | |
63 | ;;; directory/username/host tracking: the only drawback is that you will | |
64 | ;;; have to modify your shell start-up script. It's worth it, believe me :). | |
65 | ;;; | |
66 | ;;; When you rlogin/su/telnet and the account you access has a modified | |
67 | ;;; startup script, you will be able to access the remote files as usual | |
68 | ;;; with C-x C-f, if it's needed you will have to enter a password, | |
69 | ;;; otherwise the file should get loaded straight away. | |
70 | ;;; | |
71 | ;;; This is useful even if you work only on one host: it often happens that, | |
72 | ;;; for maintenance reasons, you have to edit files 'as root': before | |
73 | ;;; patching term.el, I su-ed in a term.el buffer and used vi :), now I | |
74 | ;;; simply do a C-x C-f and, via ange-ftp, the file is automatically loaded | |
75 | ;;; 'as-root'. ( If you don't want to enter the root password every time you | |
76 | ;;; can put it in your .netrc: note that this is -not- advisable if you're | |
77 | ;;; connected to the internet or if somebody else works on your workstation!) | |
78 | ;;; | |
79 | ;;; If you use wu-ftpd you can use some of its features to avoid root ftp | |
80 | ;;; access to the rest of the world: just put in /etc/ftphosts something like | |
81 | ;;; | |
82 | ;;; # Local access | |
83 | ;;; allow root 127.0.0.1 | |
84 | ;;; | |
85 | ;;; # By default nobody can't do anything | |
86 | ;;; deny root * | |
87 | ;;; | |
88 | ;;; | |
89 | ;;; ---------------------------------------- | |
90 | ;;; | |
91 | ;;; If, instead of 'term', you call 'ansi-term', you get multiple term | |
92 | ;;; buffers, after every new call ansi-term opens a new *ansi-term*<xx> window, | |
93 | ;;; where <xx> is, as usual, a number... | |
94 | ;;; | |
95 | ;;; ---------------------------------------- | |
96 | ;;; | |
97 | ;;; With the term-buffer-maximum-size you can finally decide how many | |
98 | ;;; scrollback lines to keep: its default is 2048 but you can change it as | |
99 | ;;; usual. | |
100 | ;;; | |
101 | ;;; ---------------------------------------- | |
102 | ;;; | |
103 | ;;; | |
104 | ;;; ANSI colorization should work well, I've decided to limit the interpreter | |
105 | ;;; to five outstanding commands (like ESC [ 01;04;32;41;07m. | |
106 | ;;; You shouldn't need more, if you do, tell me and I'll increase it. It's | |
107 | ;;; so easy you could do it yourself... | |
108 | ;;; | |
109 | ;;; Blink, is not supported. Currently it's mapped as bold. | |
110 | ;;; | |
111 | ;;; Important caveat: | |
112 | ;;; ----------------- | |
113 | ;;; if you want custom colors in term.el redefine term-default-fg-color | |
114 | ;;; and term-default-bg-color BEFORE loading it. | |
115 | ;;; | |
116 | ;;; ---------------------------------------- | |
117 | ;;; | |
118 | ;;; If you'd like to check out my complete configuration, you can download | |
119 | ;;; it from http://www.polito.it/~s64912/things.html, it's ~500k in size and | |
120 | ;;; contains my .cshrc, .emacs and my whole site-lisp subdirectory. (notice | |
121 | ;;; that this term.el may be newer/older than the one in there, please | |
122 | ;;; check!) | |
123 | ;;; | |
124 | ;;; This complete configuration contains, among other things, a complete | |
125 | ;;; rectangular marking solution (based on rect-mark.el and | |
126 | ;;; pc-bindings.el) and should be a good example of how extensively Emacs | |
127 | ;;; can be configured on a ppp-connected ws. | |
128 | ;;; | |
129 | ;;; ---------------------------------------- | |
130 | ;;; | |
131 | ;;; TODO: | |
132 | ;;; | |
133 | ;;; - Add hooks to allow raw-mode keys to be configurable | |
134 | ;;; - Which keys are better ? \eOA or \e[A ? | |
135 | ;;; | |
136 | ;;; | |
137 | ;;; Changes: | |
138 | ;;; | |
139 | ;;; V4.0 January 1997 | |
140 | ;;; | |
141 | ;;; - Huge reworking of the faces code: now we only have roughly 20-30 | |
142 | ;;; faces for everything so we're even faster than the old md-term.el ! | |
143 | ;;; - Finished removing all the J-Shell code. | |
144 | ;;; | |
145 | ;;; V3.0 January 1997 | |
146 | ;;; | |
147 | ;;; - Now all the supportable ANSI commands work well. | |
148 | ;;; - Reworked a little the code: much less jsh-inspired stuff | |
149 | ;;; | |
150 | ;;; V2.3 November | |
151 | ;;; | |
152 | ;;; - Now all the faces are accessed through an array: much cleaner code. | |
153 | ;;; | |
154 | ;;; V2.2 November 4 1996 | |
155 | ;;; | |
156 | ;;; - Implemented ANSI output colorization ( a bit rough but enough for | |
157 | ;;; color_ls ) | |
158 | ;;; | |
159 | ;;; - Implemented a maximum limit for the scroll buffer (stolen from | |
160 | ;;; comint.el) | |
161 | ;;; | |
162 | ;;; v2.1 October 28 1996, first public release | |
163 | ;;; | |
164 | ;;; - Some new keybindings for term-char mode ( notably home/end/...) | |
165 | ;;; - Directory, hostname and username tracking via ange-ftp | |
166 | ;;; - Multi-term capability via the ansi-term call | |
167 | ;;; | |
168 | ;;; ---------------------------------------------------------------- | |
169 | ;;; You should/could have something like this in your .emacs to take | |
170 | ;;; full advantage of this package | |
171 | ;;; | |
172 | ;;; (add-hook 'term-mode-hook | |
173 | ;;; (function | |
174 | ;;; (lambda () | |
175 | ;;; (setq term-prompt-regexp "^[^#$%>\n]*[#$%>] *") | |
176 | ;;; (make-local-variable 'mouse-yank-at-point) | |
177 | ;;; (make-local-variable 'transient-mark-mode) | |
178 | ;;; (setq mouse-yank-at-point t) | |
179 | ;;; (setq transient-mark-mode nil) | |
180 | ;;; (auto-fill-mode -1) | |
181 | ;;; (setq tab-width 8 )))) | |
182 | ;;; | |
183 | ;;; | |
184 | ;;; ---------------------------------------- | |
185 | ;;; | |
186 | ;;; If you want to use color ls the best setup is to have a different file | |
187 | ;;; when you use eterm ( see above, mine is named .emacs_dircolors ). This | |
188 | ;;; is necessary because some terminals, rxvt for example, need non-ansi | |
189 | ;;; hacks to work ( for example on my rxvt white is wired to fg, and to | |
190 | ;;; obtain normal white I have to do bold-white :) | |
191 | ;;; | |

199 | ;;; | |
200 | ;;; # COLOR needs one of these arguments: 'tty' colorizes output to ttys, but | |

931 | The interpreter name is same as buffer name, sans the asterisks. | |
932 | ||
933 | There are two submodes: line mode and char mode. By default, you are | |
934 | in char mode. In char sub-mode, each character (except | |
935 | `term-escape-char') is set immediately. | |
936 | ||
937 | In line mode, you send a line of input at a time; use | |
938 | \\[term-send-input] to send. | |
939 | ||
940 | In line mode, this maintains an input history of size | |
941 | `term-input-ring-size', and you can access it with the commands | |
942 | \\[term-next-input], \\[term-previous-input], and | |
943 | \\[term-dynamic-list-input-ring]. Input ring history expansion can be | |
944 | achieved with the commands \\[term-replace-by-expanded-history] or | |
945 | \\[term-magic-space]. Input ring expansion is controlled by the | |
946 | variable `term-input-autoexpand', and addition is controlled by the | |
947 | variable `term-input-ignoredups'. | |
948 | ||
949 | Input to, and output from, the subprocess can cause the window to scroll to | |
950 | the end of the buffer. See variables `term-scroll-to-bottom-on-input', | |
951 | and `term-scroll-to-bottom-on-output'. | |
952 | ||
953 | If you accidentally suspend your process, use \\[term-continue-subjob] | |
954 | to continue it. | |
955 | ||
956 | This mode can be customised to create specific modes for running | |
957 | particular subprocesses. This can be done by setting the hooks | |
958 | `term-input-filter-functions', `term-input-filter', | |
959 | `term-input-sender' and `term-get-old-input' to appropriate functions, | |
960 | and the variable `term-prompt-regexp' to the appropriate regular | |
961 | expression. | |

1883 | value of `term-input-filter-functions' is called on the input before sending | |

1898 | in the buffer. E.g., | |
1899 | ||
1900 | If the interpreter is the csh, | |
1901 | term-get-old-input is the default: take the current line, discard any | |
1902 | initial string matching regexp term-prompt-regexp. | |
1903 | term-input-filter-functions monitors input for \"cd\", \"pushd\", and | |
ce0ba762 | 1904 | \"popd\" commands. When it sees one, it cd's the buffer. |
0ff9b955 | 1905 | term-input-filter is the default: returns t if the input isn't all white |
4060e6ee RS |
1906 | space. |
1907 | ||
ce0ba762 | 1908 | If the term is Lucid Common Lisp, |
4060e6ee RS |
1909 | term-get-old-input snarfs the sexp ending at point. |
1910 | term-input-filter-functions does nothing. | |
0ff9b955 | 1911 | term-input-filter returns nil if the input matches input-filter-regexp, |
