30 ;; This mode is for IDL version 5 or later. It should work on
31 ;; Emacs>20.3 or XEmacs>20.4.
33 ;; Runs IDL as an inferior process of Emacs, much like the emacs
34 ;; `shell' or `telnet' commands. Provides command history and
35 ;; searching. Provides debugging commands available in buffers
36 ;; visiting IDL procedure files, e.g., breakpoint setting, stepping,
37 ;; execution until a certain line, printing expressions under point,
38 ;; visual line pointer for current execution line, etc.
40 ;; Documentation should be available online with `M-x idlwave-info'.
42 ;; New versions of IDLWAVE, documentation, and more information
49 ;; Follow the instructions in the INSTALL file of the distribution.
50 ;; In short, put this file on your load path and add the following
51 ;; lines to your .emacs file:
53 ;; (autoload 'idlwave-shell "idlw-shell" "IDLWAVE Shell" t)
59 ;; The newest version of this file can be found on the maintainers
67 ;; IDLWAVE is documented online in info format.
68 ;; A printable version of the documentation is available from the
69 ;; maintainers webpage (see under SOURCE)
75 ;; Under XEmacs the Debug menu in the shell does not display the
76 ;; keybindings in the prefix map. There bindings are available anyway - so
77 ;; it is a bug in XEmacs.
78 ;; The Debug menu in source buffers *does* display the bindings correctly.
81 ;; CUSTOMIZATION VARIABLES
82 ;; =======================

377 prompts for a single character and sends it immediately to IDL, similar
378 to the command \\[idlwave-shell-send-char].
380 When the second regexp matches, IDLWAVE switches to a blocking
381 single-character input mode. This is the same mode which can be entered
382 manually with \\[idlwave-shell-char-mode-loop].
383 This input mode exits when the third regexp matches in the output,

387 scanning for these expressions. If the IDL program produces lots of
388 output, shell operation may be slowed down.

391 GET_KBRD, because in normal operation IDLWAVE only sends \\n terminated
392 strings. Here is some example code which makes use of the default spells.

863 similar to M-TAB in `idlwave-mode'. In executive commands and

871 the one whose argument list is being edited.

1778 It is very difficult to come up with a robust solution. This one seems
1779 to be pretty good though.
1781 Here is in what ways it improves over the previous solution:
1783 1. The procedure name can be split and will be restored.
1784 2. The number can be split. I have never seen this, but who knows.
1785 3. We do not require the `.pro' extension for files.
1787 This function can still break when the file name ends on a end line
1788 and the message line contains an additional line with garbage. Then
1789 the first part of that garbage will be added to the file name.
1790 However, the function checks the existence of the files with and
1791 without this last part - thus the function only breaks if file name
