29 | ;;; Commentary: | |
30 | ||
31 | ;; This mode is for IDL version 4 or later. It should work on Emacs | |
32 | ;; or XEmacs version 19 or later. | |
33 | ||
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. | |
40 | ;; | |
41 | ;; Documentation should be available online with `M-x idlwave-info'. | |
42 | ||
43 | ;; INSTALLATION: | |
44 | ;; ============= | |
45 | ;; | |
46 | ;; Follow the instructions in the INSTALL file of the distribution. | |
47 | ;; In short, put this file on your load path and add the following | |
48 | ;; lines to your .emacs file: | |
49 | ;; | |
50 | ;; (autoload 'idlwave-shell "idlw-shell" "IDLWAVE Shell" t) | |
51 | ;; | |
52 | ;; | |
53 | ;; SOURCE | |
54 | ;; ====== | |
55 | ;; | |
56 | ;; The newest version of this file can be found on the maintainers | |
57 | ;; web site. | |
58 | ;; | |
59 | ;; http://www.strw.leidenuniv.el/~dominik/Tools/idlwave | |
60 | ;; | |
61 | ;; DOCUMENTATION | |
62 | ;; ============= | |
63 | ;; | |
64 | ;; IDLWAVE is documented online in info format. | |
65 | ;; A printable version of the documentation is available from the | |
66 | ;; maintainers webpage (see under SOURCE) | |
67 | ;; | |
68 | ;; | |
69 | ;; KNOWN PROBLEMS | |
70 | ;; ============== | |
71 | ;; | |
8c7b4ec8 EZ |
72 | ;; I don't plan on implementing directory tracking by watching the IDL |
73 | ;; commands entered at the prompt, since too often an IDL procedure | |
74 | ;; will change the current directory. If you want the the idl process | |
75 | ;; buffer to match the IDL current working just execute `M-x | |
76 | ;; idlwave-shell-resync-dirs' (bound to "\C-c\C-d\C-w" by default.) | |
77 | ;; | |
8c7b4ec8 EZ |
78 | ;; Under XEmacs the Debug menu in the shell does not display the |
79 | ;; keybindings in the prefix map. There bindings are available anyway - so | |
80 | ;; it is a bug in XEmacs. | |
ca660d22 | 81 | ;; The Debug menu in source buffers *does* display the bindings correctly. |
8c7b4ec8 EZ |
82 | ;; |
83 | ;; | |
84 | ;; CUSTOMIZATION VARIABLES | |
85 | ;; ======================= | |
86 | ;; | |
87 | ;; IDLWAVE has customize support - so if you want to learn about | |
88 | ;; the variables which control the behavior of the mode, use | |
89 | ;; `M-x idlwave-customize'. | |

258 | ||
259 | When the first regexp matches in the output streem of IDL, IDLWAVE | |
260 | prompts for a single character and sends it immediately to IDL, similar | |
261 | to the command \\[idlwave-shell-send-char]. | |
262 | ||
263 | When the second regexp matches, IDLWAVE switches to a blocking | |
264 | single-character input mode. This is the same mode which can be entered | |
265 | manually with \\[idlwave-shell-char-mode-loop]. | |
266 | This input mode exits when the third regexp matches in the output, | |
267 | or when the IDL prompt is encountered. | |
268 | ||
269 | The variable `idlwave-shell-use-input-mode-magic' must be non-nil to enable | |
270 | scanning for these expressions. If the IDL program produces lots of | |
271 | output, shell operation may be slowed down. | |
272 | ||
273 | This mechanism is useful for correct interaction with the IDL function | |
274 | GET_KBRD, because in normal operation IDLWAVE only sends \\n terminated | |
275 | strings. Here is some example code which makes use of teh default spells. | |
276 | ||
277 | print,'<chars>' ; Make IDLWAVE switch to character mode | |
278 | REPEAT BEGIN | |
279 | A = GET_KBRD(1) | |

286 | answer = GET_KBRD(1) | |

592 | ||
593 | 1. Shell Interaction | |
594 | ----------------- | |
595 | RET after the end of the process' output sends the text from the | |
596 | end of process to the end of the current line. RET before end of | |
597 | process output copies the current line (except for the prompt) to the | |
598 | end of the buffer. | |
599 | ||
600 | Command history, searching of previous commands, command line | |
601 | editing are available via the comint-mode key bindings, by default | |
602 | mostly on the key `C-c'. | |
603 | ||
604 | 2. Completion | |
605 | ---------- | |
15e42531 CD |
606 | TAB and M-TAB do completion of IDL routines, classes and keywords - |
607 | similar to M-TAB in `idlwave-mode'. In executive commands and | |
608 | strings, it completes file names. Abbreviations are also expanded | |
609 | like in `idlwave-mode'. | |
8c7b4ec8 EZ |
610 | |
611 | 3. Routine Info | |
612 | ------------ | |
613 | `\\[idlwave-routine-info]' displays information about an IDL routine near point, | |
614 | just like in `idlwave-mode'. The module used is the one at point or | |
615 | the one whose argument list is being edited. | |
616 | To update IDLWAVE's knowledge about compiled or edited modules, use | |
617 | \\[idlwave-update-routine-info]. | |
618 | \\[idlwave-find-module] find the source of a module. | |
619 | \\[idlwave-resolve] tells IDL to compile an unresolved module. | |
15e42531 CD |
620 | \\[idlwave-context-help] shows the online help on the item at |
621 | point, if online help has been installed. | |
622 | ||
8c7b4ec8 EZ |
623 | |
624 | 4. Debugging | |
625 | --------- | |
626 | A complete set of commands for compiling and debugging IDL programs | |
627 | is available from the menu. Also keybindings starting with a | |
628 | `C-c C-d' prefix are available for most commands in the *idl* buffer | |
629 | and also in source buffers. The best place to learn about the | |
630 | keybindings is again the menu. | |
631 | ||
632 | On Emacs versions where this is possible, a debugging toolbar is | |
633 | installed. | |
634 | ||
635 | When IDL is halted in the middle of a procedure, the corresponding | |
636 | line of that procedure file is displayed with an overlay in another | |
637 | window. Breakpoints are also highlighted in the source. | |
638 | ||
639 | \\[idlwave-shell-resync-dirs] queries IDL in order to change Emacs current directory | |
640 | to correspond to the IDL process current directory. | |
641 | ||
642 | 5. Hooks | |
643 | ----- | |
644 | Turning on `idlwave-shell-mode' runs `comint-mode-hook' and | |
645 | `idlwave-shell-mode-hook' (in that order). | |
646 | ||
647 | 6. Documentation and Customization | |
648 | ------------------------------- | |
649 | Info documentation for this package is available. Use \\[idlwave-info] | |
650 | to display (complain to your sysadmin if that does not work). | |
651 | For Postscript and HTML versions of the documentation, check IDLWAVE's | |
652 | homepage at `http://www.strw.leidenuniv.nl/~dominik/Tools/idlwave'. | |
653 | IDLWAVE has customize support - see the group `idlwave'. | |

1253 | We need to work hard here to remove the stupid line breaks inserted by | |
1254 | IDL5. These line breaks can be right in the middle of procedure | |
1255 | or file names. | |
1256 | It is very difficult to come up with a robust solution. This one seems | |
1257 | to be pretty good though. | |
1258 | ||
1259 | Here is in what ways it improves over the previous solution: | |
1260 | ||
1261 | 1. The procedure name can be split and will be restored. | |
1262 | 2. The number can be split. I have never seen this, but who knows. | |
1263 | 3. We do not require the `.pro' extension for files. | |
1264 | ||
1265 | This function can still break when the file name ends on a end line | |
1266 | and the message line contains an additional line with garbage. Then | |
1267 | the first part of that garbage will be added to the file name. | |
1268 | However, the function checks the existence of the files with and | |
1269 | without this last part - thus the function only breaks if file name | |
1270 | plus garbage match an existing regular file. This is hopefully very | |
1271 | unlikely." | |
