|
;; HOW TO INSTALL:
|
28 |
|
|
;; Put the following forms in your .emacs to enable autoloading of Tcl
|
29 |
|
|
;; mode, and auto-recognition of ".tcl" files.
|
30 |
|
|
;;
|
31 |
|
|
;; (autoload 'tcl-mode "tcl" "Tcl mode." t)
|
32 |
|
|
;; (autoload 'inferior-tcl "tcl" "Run inferior Tcl process." t)
|
33 |
|
|
;; (setq auto-mode-alist (append '(("\\.tcl$" . tcl-mode)) auto-mode-alist))
|
34 |
|
|
;;
|
35 |
|
|
;; If you plan to use the interface to the TclX help files, you must
|
36 |
|
|
;; set the variable tcl-help-directory-list to point to the topmost
|
37 |
|
|
;; directories containing the TclX help files. Eg:
|
38 |
|
|
;;
|
39 |
|
|
;; (setq tcl-help-directory-list '("/usr/local/lib/tclx/help"))
|
40 |
|
|
;;
|
41 |
|
|
;; Also you will want to add the following to your .emacs:
|
42 |
|
|
;;
|
43 |
|
|
;; (autoload 'tcl-help-on-word "tcl" "Help on Tcl commands" t)
|
44 |
|
|
;;
|
45 |
|
|
;; FYI a *very* useful thing to do is nroff all the Tk man pages and
|
46 |
|
|
;; put them in a subdir of the help system.

;; CUSTOMIZATION NOTES:
|
57 |
|
|
;; * tcl-proc-list can be used to customize a list of things that
|
58 |
|
|
;; "define" other things. Eg in my project I put "defvar" in this
|
59 |
|
|
;; list.
|
60 |
|
|
;; * tcl-typeword-list is similar, but uses font-lock-type-face.
|
61 |
|
|
;; * tcl-keyword-list is a list of keywords. I've generally used this
|
62 |
|
|
;; for flow-control words. Eg I add "unwind_protect" to this list.
|
63 |
|
|
;; * tcl-type-alist can be used to minimally customize indentation
|
64 |
|
|
;; according to context.

;; KNOWN BUGS:
|
299 |
|
|
;; * indent-region should skip blank lines. (It does in v19, so I'm
|
300 |
|
|
;; not motivated to fix it here).
|
301 |
|
|
;; * In Tcl "#" is not always a comment character. This can confuse
|
302 |
|
|
;; tcl.el in certain circumstances. For now the only workaround is
|
303 |
|
|
;; to enclose offending hash characters in quotes or precede it with
|
304 |
|
|
;; a backslash. Note that using braces won't work -- quotes change
|
305 |
|
|
;; the syntax class of characters between them, while braces do not.
|
306 |
|
|
;; The electric-# mode helps alleviate this problem somewhat.
|
307 |
|
|
;; * indent-tcl-exp is untested.
|
308 |
|
|
;; * Doesn't work under Emacs 18 yet.
|
309 |
|
|
;; * There's been a report that font-lock does strange things under
|
310 |
|
|
;; Lucid Emacs 19.6. For instance in "proc foobar", the space
|
311 |
|
|
;; before "foobar" is highlighted.
|
312 |
|
|
|
313 |
|
|
;; TODO:
|
314 |
|
|
;; * make add-log-tcl-defun smarter. should notice if we are in the
|
315 |
|
|
;; middle of a defun, or between defuns. should notice if point is
|
316 |
|
|
;; on first line of defun (or maybe even in comments before defun).
|
317 |
|
|
;; * Allow continuation lines to be indented under the first argument
|
318 |
|
|
;; of the preceeding line, like this:
|
319 |
|
|
;; [list something \
|
320 |
|
|
;; something-else]
|
321 |
|
|
;; * There is a request that indentation work like this:
|
322 |
|
|
;; button .fred -label Fred \
|
323 |
|
|
;; -command {puts fred}
|
324 |
|
|
;; * Should have tcl-complete-symbol that queries the inferior process.
|
325 |
|
|
;; * Should have describe-symbol that works by sending the magic
|
326 |
|
|
;; command to a tclX process.
|
327 |
|
|
;; * Need C-x C-e binding (tcl-eval-last-exp).
|
328 |
|
|
;; * Write indent-region function that is faster than indenting each
|
329 |
|
|
;; line individually.
|
330 |
|
|
;; * tcl-figure-type should stop at "beginning of line" (only ws
|
331 |
|
|
;; before point, and no "\" on previous line). (see tcl-real-command-p).
|
332 |
|
|
;; * overrides some comint keybindings; fix.
|
333 |
|
|
;; * Trailing \ will eat blank lines. Should deal with this.
|
334 |
|
|
;; (this would help catch some potential bugs).
|
335 |
|
|
;; * Inferior should display in half the screen, not the whole screen.
|
336 |
|
|
;; * Indentation should deal with "switch".
|
337 |
|
|
;; * Consider writing code to find help files automatically (for
|
338 |
|
|
;; common cases).
|
339 |
|
|
;; * `#' shouldn't insert `\#' when point is in string.

MULTIPLE PROCESS SUPPORT
|
586 |
|
|
===========================================================================
|
587 |
|
|
To run multiple Tcl processes, you start the first up with
|
588 |
|
|
\\[inferior-tcl]. It will be in a buffer named `*inferior-tcl*'.
|
589 |
|
|
Rename this buffer with \\[rename-buffer]. You may now start up a new
|
590 |
|
|
process with another \\[inferior-tcl]. It will be in a new buffer,
|
591 |
|
|
named `*inferior-tcl*'. You can switch between the different process
|
592 |
|
|
buffers with \\[switch-to-buffer].
|
593 |
|
|
|
594 |
|
|
Commands that send text from source buffers to Tcl processes -- like
|
595 |
|
|
`tcl-eval-defun' or `tcl-load-file' -- have to choose a process to
|
596 |
|
|
send to, when you have more than one Tcl process around. This is
|
597 |
|
|
determined by the global variable `inferior-tcl-buffer'. Suppose you
|
598 |
|
|
have three inferior Lisps running:
|
599 |
|
|
Buffer Process
|
600 |
|
|
foo inferior-tcl
|
601 |
|
|
bar inferior-tcl<2>
|
602 |
|
|
*inferior-tcl* inferior-tcl<3>
|
603 |
|
|
If you do a \\[tcl-eval-defun] command on some Lisp source code, what
|
604 |
|
|
process do you send it to?
|
605 |
|
|
|
606 |
|
|
- If you're in a process buffer (foo, bar, or *inferior-tcl*),
|
607 |
|
|
you send it to that process.
|
608 |
|
|
- If you're in some other buffer (e.g., a source file), you
|
609 |
|
|
send it to the process attached to buffer `inferior-tcl-buffer'.
|
610 |
|
|
This process selection is performed by function `inferior-tcl-proc'.
|
611 |
|
|
|
612 |
|
|
Whenever \\[inferior-tcl] fires up a new process, it resets
|
613 |
|
|
`inferior-tcl-buffer' to be the new process's buffer. If you only run
|
614 |
|
|
one process, this does the right thing. If you run multiple
|
615 |
|
|
processes, you can change `inferior-tcl-buffer' to another process
|
616 |
|
|
buffer with \\[set-variable].")
