;;; Commentary:
;;
;; This mode is for IDL version 5 or later. It should work on
;; Emacs>20.3 or XEmacs>20.4.
;;
;; Runs IDL as an inferior process of Emacs, much like the Emacs
;; `shell' or `telnet' commands. Provides command history and
;; searching. Provides debugging commands available in buffers
;; visiting IDL procedure files, e.g., breakpoint setting, stepping,
;; execution until a certain line, printing expressions under point,
;; visual line pointer for current execution line, etc.
;;
;; Documentation should be available online with `M-x idlwave-info'.
;;
;; New versions of IDLWAVE, documentation, and more information
;; available from:
;; http://idlwave.org
;;
;; INSTALLATION:
;; =============
;;
;; Follow the instructions in the INSTALL file of the distribution.
;; In short, put this file on your load path and add the following
;; lines to your .emacs file:
;;
;; (autoload 'idlwave-shell "idlw-shell" "IDLWAVE Shell" t)
;;
;;
;; SOURCE
;; ======
;;
;; The newest version of this file can be found on the maintainers
;; web site.
;;
;; http://idlwave.org
;;
;; DOCUMENTATION
;; =============
;;
;; IDLWAVE is documented online in info format.
;; A printable version of the documentation is available from the
;; maintainers webpage (see under SOURCE)
;;
;;
;; KNOWN PROBLEMS
;; ==============
;;
;; Under XEmacs the Debug menu in the shell does not display the
;; keybindings in the prefix map. There bindings are available anyway - so
;; it is a bug in XEmacs.
;; The Debug menu in source buffers *does* display the bindings correctly.
;;
;;
;; CUSTOMIZATION VARIABLES
;; =======================
;;
;; IDLWAVE has customize support - so if you want to learn about
;; the variables which control the behavior of the mode, use
;; `M-x idlwave-customize'.

"The three regular expressions which match the magic spells for input modes.
When the first regexp matches in the output stream of IDL, IDLWAVE
prompts for a single character and sends it immediately to IDL, similar
to the command \\[idlwave-shell-send-char].
When the second regexp matches, IDLWAVE switches to a blocking
single-character input mode. This is the same mode which can be entered
manually with \\[idlwave-shell-char-mode-loop].
This input mode exits when the third regexp matches in the output,
or when the IDL prompt is encountered.
The variable `idlwave-shell-use-input-mode-magic' must be non-nil to enable
scanning for these expressions. If the IDL program produces lots of
output, shell operation may be slowed down.
This mechanism is useful for correct interaction with the IDL function
GET_KBRD, because in normal operation IDLWAVE only sends \\n terminated
strings. Here is some example code which makes use of the default spells.
print,'<chars>' ; Make IDLWAVE switch to character mode
REPEAT BEGIN
A = GET_KBRD(1)
PRINT, BYTE(A)
ENDREP UNTIL A EQ 'q'
print,'</chars>' ; Make IDLWAVE switch back to line mode
print,'Quit the program, y or n?'
print,'<onechar>' ; Ask IDLWAVE to send one character
answer = GET_KBRD(1)
Since the IDLWAVE shell defines the system variable `!IDLWAVE_VERSION',
you could actually check if you are running under Emacs before printing
the magic strings. Here is a procedure which uses this.
Usage:
======
idlwave_char_input ; Make IDLWAVE send one character
idlwave_char_input,/on ; Start the loop to send characters
idlwave_char_input,/off ; End the loop to send characters
pro idlwave_char_input,on=on,off=off
;; Test if we are running under Emacs
defsysv,'!idlwave_version',exists=running_emacs
if running_emacs then begin
if keyword_set(on) then print,'<chars>' $
else if keyword_set(off) then print,'</chars>' $
else print,'<onechar>'

"Major mode for interacting with an inferior IDL process.
1. Shell Interaction
-----------------
RET after the end of the process' output sends the text from the
end of process to the end of the current line. RET before end of
process output copies the current line (except for the prompt) to the
end of the buffer.
Command history, searching of previous commands, command line
editing are available via the comint-mode key bindings, by default
mostly on the key `C-c'. Command history is also available with
the arrow keys UP and DOWN.
2. Completion
----------
TAB and M-TAB do completion of IDL routines, classes and keywords -
similar to M-TAB in `idlwave-mode'. In executive commands and
strings, it completes file names. Abbreviations are also expanded
like in `idlwave-mode'.
3. Routine Info
------------
`\\[idlwave-routine-info]' displays information about an IDL routine near point,
just like in `idlwave-mode'. The module used is the one at point or
the one whose argument list is being edited.
To update IDLWAVE's knowledge about compiled or edited modules, use
\\[idlwave-update-routine-info].
\\[idlwave-find-module] find the source of a module.
\\[idlwave-resolve] tells IDL to compile an unresolved module.
\\[idlwave-context-help] shows the online help on the item at
point, if online help has been installed.
4. Debugging
---------
A complete set of commands for compiling and debugging IDL programs
is available from the menu. Also keybindings starting with a
`C-c C-d' prefix are available for most commands in the *idl* buffer
and also in source buffers. The best place to learn about the
keybindings is again the menu.
On Emacs versions where this is possible, a debugging toolbar is
installed.
When IDL is halted in the middle of a procedure, the corresponding
line of that procedure file is displayed with an overlay in another
window. Breakpoints are also highlighted in the source.
\\[idlwave-shell-resync-dirs] queries IDL in order to change Emacs current directory
to correspond to the IDL process current directory.
5. Expression Examination
----------------------
Expressions near point can be examined with print,
\\[idlwave-shell-print] or \\[idlwave-shell-mouse-print] with the
mouse, help, \\[idlwave-shell-help-expression] or
\\[idlwave-shell-mouse-help] with the mouse, or with a
configureable set of custom examine commands using
\\[idlwave-shell-examine-select]. The mouse examine commands can
also work by click and drag, to select an expression for
examination.
6. Hooks
-----
Turning on `idlwave-shell-mode' runs `comint-mode-hook' and
`idlwave-shell-mode-hook' (in that order).
7. Documentation and Customization
-------------------------------
Info documentation for this package is available. Use \\[idlwave-info]
to display (complain to your sysadmin if that does not work).
For Postscript and HTML versions of the documentation, check IDLWAVE's
homepage at `http://idlwave.org'.
IDLWAVE has customize support - see the group `idlwave'.

;It is very difficult to come up with a robust solution. This one seems

;
;1. The procedure name can be split and will be restored.

;
;This function can still break when the file name ends on an end line
;and the message line contains an additional line with garbage. Then
;the first part of that garbage will be added to the file name.
;However, the function checks the existence of the files with and
;without this last part - thus the function only breaks if file name
;plus garbage match an existing regular file. This is hopefully very
;unlikely.
