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

378 prompts for a single character and sends it immediately to IDL, similar
379 to the command \\[idlwave-shell-send-char].
381 When the second regexp matches, IDLWAVE switches to a blocking
382 single-character input mode. This is the same mode which can be entered
383 manually with \\[idlwave-shell-char-mode-loop].
384 This input mode exits when the third regexp matches in the output,
385 or when the IDL prompt is encountered.
387 The variable `idlwave-shell-use-input-mode-magic' must be non-nil to enable
388 scanning for these expressions. If the IDL program produces lots of
389 output, shell operation may be slowed down.

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

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

1780 It is very difficult to come up with a robust solution. This one seems
1781 to be pretty good though.
1783 Here is in what ways it improves over the previous solution:
1785 1. The procedure name can be split and will be restored.
1786 2. The number can be split. I have never seen this, but who knows.
1787 3. We do not require the `.pro' extension for files.
1789 This function can still break when the file name ends on a end line
1790 and the message line contains an additional line with garbage. Then
1791 the first part of that garbage will be added to the file name.
1792 However, the function checks the existence of the files with and
1793 without this last part - thus the function only breaks if file name
