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 ;; =======================
84 ;; IDLWAVE has customize support - so if you want to learn about
85 ;; the variables which control the behavior of the mode, use

379 When the first regexp matches in the output stream of IDL, IDLWAVE
380 prompts for a single character and sends it immediately to IDL, similar
381 to the command \\[idlwave-shell-send-char].
383 When the second regexp matches, IDLWAVE switches to a blocking
384 single-character input mode. This is the same mode which can be entered
385 manually with \\[idlwave-shell-char-mode-loop].
386 This input mode exits when the third regexp matches in the output,
387 or when the IDL prompt is encountered.
389 The variable `idlwave-shell-use-input-mode-magic' must be non-nil to enable
390 scanning for these expressions. If the IDL program produces lots of
391 output, shell operation may be slowed down.
393 This mechanism is useful for correct interaction with the IDL function
394 GET_KBRD, because in normal operation IDLWAVE only sends \\n terminated
395 strings. Here is some example code which makes use of the default spells.

881 mostly on the key `C-c'. Command history is also available with
882 the arrow keys UP and DOWN.
886 TAB and M-TAB do completion of IDL routines, classes and keywords -
887 similar to M-TAB in `idlwave-mode'. In executive commands and
888 strings, it completes file names. Abbreviations are also expanded
889 like in `idlwave-mode'.
893 `\\[idlwave-routine-info]' displays information about an IDL routine near point,
894 just like in `idlwave-mode'. The module used is the one at point or
895 the one whose argument list is being edited.
896 To update IDLWAVE's knowledge about compiled or edited modules, use
897 \\[idlwave-update-routine-info].
898 \\[idlwave-find-module] find the source of a module.
899 \\[idlwave-resolve] tells IDL to compile an unresolved module.
900 \\[idlwave-context-help] shows the online help on the item at
901 point, if online help has been installed.
906 A complete set of commands for compiling and debugging IDL programs
907 is available from the menu. Also keybindings starting with a
908 `C-c C-d' prefix are available for most commands in the *idl* buffer
909 and also in source buffers. The best place to learn about the

912 On Emacs versions where this is possible, a debugging toolbar is
915 When IDL is halted in the middle of a procedure, the corresponding
916 line of that procedure file is displayed with an overlay in another

927 mouse, help, \\[idlwave-shell-help-expression] or
928 \\[idlwave-shell-mouse-help] with the mouse, or with a

931 also work by click and drag, to select an expression for

3262 file - full path file name.
3263 line - line number of breakpoint - integer.
3265 The first element of the cdr is a list of internal IDL data:
3266 index - the index number of the breakpoint internal to IDL.
3267 module - the module for breakpoint internal to IDL.
3269 Remaining elements of the cdr:
3270 data - Data associated with the breakpoint by idlwave-shell currently
3271 contains four items:
3273 count - number of times to execute breakpoint. When count reaches 0
3274 the breakpoint is cleared and removed from the alist.
3276 command - command to execute when breakpoint is reached, either a
3277 lisp function to be called with `funcall' with no arguments or a
3278 list to be evaluated with `eval'.
3280 condition - any condition to apply to the breakpoint.
