|

|
||
;;; Author: Per Bothner <bothner@cygnus.com>
|
||
;;; Based on comint mode written by: Olin Shivers <shivers@cs.cmu.edu>
|
||
;;; Keyword: processes
|
||
|
||
;;; Dir/Hostname tracking and ANSI colorization by
|
||
;;; Marco Melgazzi <marco@techie.com>.
|
||
|
||
;;; To see what I've modified and where it came from search for '-mm'
|
||
|
||
;;; Speed considerations and a few caveats
|
||
;;; --------------------------------------
|
||
;;;
|
||
;;; While the message passing and the colorization surely introduce some
|
||
;;; overhead this has became so small that IMHO is surely outweighted by
|
||
;;; the benefits you get but, as usual, YMMV
|
||
;;;
|
||
;;; Important caveat, when deciding the cursor/'grey keys' keycodes I had to
|
||
;;; make a choice: on my Linux box this choice allows me to run all the
|
||
;;; ncurses applications without problems but make these keys
|
||
;;; uncomprehensible to all the cursesX programs. Your mileage may vary so
|
||
;;; you may consider changing the default 'emulation'. Just search for this
|
||
;;; piece of code and modify it as you like:
|
||
;;;
|
||
;;; ;; Which would be better: "\e[A" or "\eOA"? readline accepts either.
|
||
;;; ;; For my configuration it's definitely better \eOA but YMMV. -mm
|
||
;;; ;; For example: vi works with \eOA while elm wants \e[A ...
|
||
;;; (defun term-send-up () (interactive) (term-send-raw-string "\eOA"))
|
||
;;; (defun term-send-down () (interactive) (term-send-raw-string "\eOB"))
|
||
;;; (defun term-send-right () (interactive) (term-send-raw-string "\eOC"))
|
||
;;; (defun term-send-left () (interactive) (term-send-raw-string "\eOD"))
|
||
;;;
|
||
;;;
|
||
;;; IMPORTANT: additions & changes
|
||
;;; ------------------------------
|
||
;;;
|
||
;;; With this enhanced ansi-term.el you will get a reliable mechanism of
|
||
;;; directory/username/host tracking: the only drawback is that you will
|
||
;;; have to modify your shell start-up script. It's worth it, believe me :).
|
||
;;;
|
||
;;; When you rlogin/su/telnet and the account you access has a modified
|
||
;;; startup script, you will be able to access the remote files as usual
|
||
;;; with C-x C-f, if it's needed you will have to enter a password,
|
||
;;; otherwise the file should get loaded straight away.
|
||
;;;
|
||
;;; This is useful even if you work only on one host: it often happens that,
|
||
;;; for maintenance reasons, you have to edit files 'as root': before
|
||
;;; patching term.el, I su-ed in a term.el buffer and used vi :), now I
|
||
;;; simply do a C-x C-f and, via ange-ftp, the file is automatically loaded
|
||
;;; 'as-root'. ( If you don't want to enter the root password every time you
|
||
;;; can put it in your .netrc: note that this is -not- advisable if you're
|
||
;;; connected to the internet or if somebody else works on your workstation!)
|
||
;;;
|
||
;;; If you use wu-ftpd you can use some of its features to avoid root ftp
|
||
;;; access to the rest of the world: just put in /etc/ftphosts something like
|
||
;;;
|
||
;;; # Local access
|
||
;;; allow root 127.0.0.1
|
||
;;;
|
||
;;; # By default nobody can't do anything
|
||
;;; deny root *
|
||
;;;
|
||
;;;
|
||
;;; ----------------------------------------
|
||
;;;
|
||
;;; If, instead of 'term', you call 'ansi-term', you get multiple term
|
||
;;; buffers, after every new call ansi-term opens a new *ansi-term*<xx> window,
|
||
;;; where <xx> is, as usual, a number...
|
||
;;;
|
||
;;; ----------------------------------------
|
||
;;;
|
||
;;; With the term-buffer-maximum-size you can finally decide how many
|
||
;;; scrollback lines to keep: its default is 2048 but you can change it as
|
||
;;; usual.
|
||
;;;
|
||
;;; ----------------------------------------
|
||
;;;
|
||
;;;
|
||
;;; ANSI colorization should work well, I've decided to limit the interpreter
|
||
;;; to five outstanding commands (like ESC [ 01;04;32;41;07m.
|
||
;;; You shouldn't need more, if you do, tell me and I'll increase it. It's
|
||
;;; so easy you could do it yourself...
|
||
;;;
|
||
;;; Blink, is not supported. Currently it's mapped as bold.
|
||
;;;
|
||
;;; Important caveat:
|
||
;;; -----------------
|
||
;;; if you want custom colors in term.el redefine term-default-fg-color
|
||
;;; and term-default-bg-color BEFORE loading it.
|
||
;;;

||

||
;;;
|
||
;;; If you'd like to check out my complete configuration, you can download
|
||
;;; it from http://www.polito.it/~s64912/things.html, it's ~500k in size and
|
||
;;; contains my .cshrc, .emacs and my whole site-lisp subdirectory. (notice
|
||
;;; that this term.el may be newer/older than the one in there, please
|
||
;;; check!)
|
||
;;;
|
||
;;; This complete configuration contains, among other things, a complete
|
||
;;; rectangular marking solution (based on rect-mark.el and
|
||
;;; pc-bindings.el) and should be a good example of how extensively Emacs
|
||
;;; can be configured on a ppp-connected ws.

|
||
;;; TODO:
|
||
;;;
|
||
;;; - Add hooks to allow raw-mode keys to be configurable
|
||
;;; - Which keys are better ? \eOA or \e[A ?
|
||
;;;
|
||
;;;
|
||
;;; Changes:
|
||
;;;
|
||
;;; V4.0 January 1997
|
||
;;;
|
||
;;; - Huge reworking of the faces code: now we only have roughly 20-30
|
||
;;; faces for everything so we're even faster than the old md-term.el !
|
||
;;; - Finished removing all the J-Shell code.
|
||
;;;
|
||
;;; V3.0 January 1997
|
||
;;;
|
||
;;; - Now all the supportable ANSI commands work well.
|
||
;;; - Reworked a little the code: much less jsh-inspired stuff
|
||
;;;
|
||
;;; V2.3 November
|
||
;;;
|
||
;;; - Now all the faces are accessed through an array: much cleaner code.
|
||
;;;
|
||
;;; V2.2 November 4 1996
|
||
;;;
|
||
;;; - Implemented ANSI output colorization ( a bit rough but enough for
|
||
;;; color_ls )
|
||
;;;
|
||
;;; - Implemented a maximum limit for the scroll buffer (stolen from
|
||
;;; comint.el)
|
||
;;;
|
||
;;; v2.1 October 28 1996, first public release
|
||
;;;
|
||
;;; - Some new keybindings for term-char mode ( notably home/end/...)
|
||
;;; - Directory, hostname and username tracking via ange-ftp
|
||
;;; - Multi-term capability via the ansi-term call
|
||
;;;
|
||
;;; ----------------------------------------------------------------
|
||
;;; You should/could have something like this in your .emacs to take
|
||
;;; full advantage of this package
|

;;;
|

;;; (add-hook 'term-mode-hook
|
||
;;; (function
|

;;;
|

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

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

;;; So the compile/load interface gets the wrong default occasionally.
|
||
;;; The load-file/compile-file default mechanism could be smarter -- it
|
||
;;; doesn't know about the relationship between filename extensions and
|
||
;;; whether the file is source or executable. If you compile foo.lisp
|
||
;;; with compile-file, then the next load-file should use foo.bin for
|

;;; the default, not foo.lisp. This is tricky to do right, particularly

|
||
;;; Renaming variables
|
||
;;; Most of the work is renaming variables and functions. These are the common
|
||
;;; ones:
|
||
;;; Local variables:
|
||
;;; last-input-start term-last-input-start
|
||
;;; last-input-end term-last-input-end
|
||
;;; shell-prompt-pattern term-prompt-regexp
|
||
;;; shell-set-directory-error-hook <no equivalent>
|
||
;;; Miscellaneous:
|
||
;;; shell-set-directory <unnecessary>
|
||
;;; shell-mode-map term-mode-map
|
||
;;; Commands:
|
||
;;; shell-send-input term-send-input
|
||
;;; shell-send-eof term-delchar-or-maybe-eof
|
||
;;; kill-shell-input term-kill-input
|
||
;;; interrupt-shell-subjob term-interrupt-subjob
|
||
;;; stop-shell-subjob term-stop-subjob
|
||
;;; quit-shell-subjob term-quit-subjob
|
||
;;; kill-shell-subjob term-kill-subjob
|
||
;;; kill-output-from-shell term-kill-output
|
||
;;; show-output-from-shell term-show-output
|
||
;;; copy-last-shell-input Use term-previous-input/term-next-input
|
||
;;;
|
||
;;; SHELL-SET-DIRECTORY is gone, its functionality taken over by
|
||
;;; SHELL-DIRECTORY-TRACKER, the shell mode's term-input-filter-functions.
|
||
;;; Term mode does not provide functionality equivalent to
|
||
;;; shell-set-directory-error-hook; it is gone.
|
||
;;;
|
||
;;; term-last-input-start is provided for modes which want to munge
|
||
;;; the buffer after input is sent, perhaps because the inferior
|
||
;;; insists on echoing the input. The LAST-INPUT-START variable in
|
||
;;; the old shell package was used to implement a history mechanism,
|
||
;;; but you should think twice before using term-last-input-start
|
||
;;; for this; the input history ring often does the job better.
|
||
;;;
|
||
;;; If you are implementing some process-in-a-buffer mode, called foo-mode, do
|
||
;;; *not* create the term-mode local variables in your foo-mode function.
|
||
;;; This is not modular. Instead, call term-mode, and let *it* create the
|
||
;;; necessary term-specific local variables. Then create the
|
||
;;; foo-mode-specific local variables in foo-mode. Set the buffer's keymap to
|
||
;;; be foo-mode-map, and its mode to be foo-mode. Set the term-mode hooks
|
||
;;; (term-{prompt-regexp, input-filter, input-filter-functions,
|
||
;;; get-old-input) that need to be different from the defaults. Call
|
||
;;; foo-mode-hook, and you're done. Don't run the term-mode hook yourself;
|
||
;;; term-mode will take care of it. The following example, from shell.el,
|
||
;;; is typical:
|
||
;;;
|
||
;;; (defvar shell-mode-map '())
|
||
;;; (cond ((not shell-mode-map)
|
||
;;; (setq shell-mode-map (copy-keymap term-mode-map))
|
||
;;; (define-key shell-mode-map "\C-c\C-f" 'shell-forward-command)
|
||
;;; (define-key shell-mode-map "\C-c\C-b" 'shell-backward-command)
|
||
;;; (define-key shell-mode-map "\t" 'term-dynamic-complete)
|
||
;;; (define-key shell-mode-map "\M-?"
|
||
;;; 'term-dynamic-list-filename-completions)))
|
||
;;;
|
||
;;; (defun shell-mode ()
|
||
;;; (interactive)
|
||
;;; (term-mode)
|
||
;;; (setq term-prompt-regexp shell-prompt-pattern)
|
||
;;; (setq major-mode 'shell-mode)
|
||
;;; (setq mode-name "Shell")
|
||
;;; (use-local-map shell-mode-map)
|
||
;;; (make-local-variable 'shell-directory-stack)
|
||
;;; (setq shell-directory-stack nil)
|
||
;;; (add-hook 'term-input-filter-functions 'shell-directory-tracker)
|
||
;;; (run-hooks 'shell-mode-hook))
|
||
;;;
|
||
;;;
|
||
;;; Completion for term-mode users
|
||
;;;
|
||
;;; For modes that use term-mode, term-dynamic-complete-functions is the
|
||
;;; hook to add completion functions to. Functions on this list should return
|
||
;;; non-nil if completion occurs (i.e., further completion should not occur).
|
||
;;; You could use term-dynamic-simple-complete to do the bulk of the
|
||
;;; completion job.
