5e72c6b2 S |
30 | ;; |
31 | ;; This mode is for IDL version 5 or later. It should work on | |
32 | ;; Emacs>20.3 or XEmacs>20.4. | |
33 | ;; | |
8c7b4ec8 EZ |
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'. | |
5e72c6b2 S |
42 | ;; |
43 | ;; New versions of IDLWAVE, documentation, and more information | |
44 | ;; available from: | |

47 | ;; INSTALLATION: |
48 | ;; ============= | |
3938cb82 | 49 | ;; |
8c7b4ec8 EZ |
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: | |
53 | ;; | |
54 | ;; (autoload 'idlwave-shell "idlw-shell" "IDLWAVE Shell" t) | |
55 | ;; | |

65 | ;; DOCUMENTATION |
66 | ;; ============= | |
67 | ;; | |
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) | |
71 | ;; | |
72 | ;; | |
73 | ;; KNOWN PROBLEMS | |
74 | ;; ============== | |
75 | ;; | |
8c7b4ec8 EZ |
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. | |
ca660d22 | 79 | ;; The Debug menu in source buffers *does* display the bindings correctly. |
8c7b4ec8 | 80 | ;; |

8c7b4ec8 EZ |
82 | ;; CUSTOMIZATION VARIABLES |
83 | ;; ======================= | |
84 | ;; | |
85 | ;; IDLWAVE has customize support - so if you want to learn about | |
86 | ;; the variables which control the behavior of the mode, use | |
87 | ;; `M-x idlwave-customize'. | |

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. | |
388 | ||
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. | |
392 | ||
393 | This mechanism is useful for correct interaction with the IDL function | |
394 | GET_KBRD, because in normal operation IDLWAVE only sends \\n terminated | |
05a1abfc | 395 | strings. Here is some example code which makes use of the default spells. |
15e42531 CD |
396 | |
397 | print,'<chars>' ; Make IDLWAVE switch to character mode | |
398 | REPEAT BEGIN | |
399 | A = GET_KBRD(1) | |
400 | PRINT, BYTE(A) | |
401 | ENDREP UNTIL A EQ 'q' | |
402 | print,'</chars>' ; Make IDLWAVE switch back to line mode | |
403 | ||
404 | print,'Quit the program, y or n?' | |
405 | print,'<onechar>' ; Ask IDLWAVE to send one character | |
406 | answer = GET_KBRD(1) | |
407 | ||
408 | Since the IDLWAVE shell defines the system variable `!IDLWAVE_VERSION', | |
3938cb82 | 409 | you could actually check if you are running under Emacs before printing |
15e42531 CD |
410 | the magic strings. Here is a procedure which uses this. |

414 | idlwave_char_input ; Make IDLWAVE send one character | |
415 | idlwave_char_input,/on ; Start the loop to send characters | |

854 | 1. Shell Interaction | |
855 | ----------------- | |
856 | RET after the end of the process' output sends the text from the | |
857 | end of process to the end of the current line. RET before end of | |
858 | process output copies the current line (except for the prompt) to the | |
859 | end of the buffer. | |
860 | ||
861 | Command history, searching of previous commands, command line | |
862 | editing are available via the comint-mode key bindings, by default | |
05a1abfc CD |
863 | mostly on the key `C-c'. Command history is also available with |
864 | the arrow keys UP and DOWN. | |
8c7b4ec8 EZ |
865 | |
866 | 2. Completion | |
867 | ---------- | |
15e42531 CD |
868 | TAB and M-TAB do completion of IDL routines, classes and keywords - |
869 | similar to M-TAB in `idlwave-mode'. In executive commands and | |
870 | strings, it completes file names. Abbreviations are also expanded | |
871 | like in `idlwave-mode'. | |
8c7b4ec8 EZ |
872 | |
873 | 3. Routine Info | |
874 | ------------ | |
875 | `\\[idlwave-routine-info]' displays information about an IDL routine near point, | |
876 | just like in `idlwave-mode'. The module used is the one at point or | |
877 | the one whose argument list is being edited. | |
3938cb82 | 878 | To update IDLWAVE's knowledge about compiled or edited modules, use |
8c7b4ec8 EZ |
879 | \\[idlwave-update-routine-info]. |
880 | \\[idlwave-find-module] find the source of a module. | |
881 | \\[idlwave-resolve] tells IDL to compile an unresolved module. | |
15e42531 CD |
882 | \\[idlwave-context-help] shows the online help on the item at |
883 | point, if online help has been installed. | |
3938cb82 | 884 | |
8c7b4ec8 EZ |
885 | |
886 | 4. Debugging | |
887 | --------- | |
888 | A complete set of commands for compiling and debugging IDL programs | |
3938cb82 | 889 | is available from the menu. Also keybindings starting with a |
8c7b4ec8 EZ |
890 | `C-c C-d' prefix are available for most commands in the *idl* buffer |
891 | and also in source buffers. The best place to learn about the | |
892 | keybindings is again the menu. | |
893 | ||
894 | On Emacs versions where this is possible, a debugging toolbar is | |
895 | installed. | |
896 | ||
897 | When IDL is halted in the middle of a procedure, the corresponding | |
898 | line of that procedure file is displayed with an overlay in another | |
899 | window. Breakpoints are also highlighted in the source. | |
900 | ||
901 | \\[idlwave-shell-resync-dirs] queries IDL in order to change Emacs current directory | |
902 | to correspond to the IDL process current directory. | |
903 | ||
52a244eb S |
904 | 5. Expression Examination |
905 | ---------------------- | |
906 | ||
907 | Expressions near point can be examined with print, | |
908 | \\[idlwave-shell-print] or \\[idlwave-shell-mouse-print] with the | |
909 | mouse, help, \\[idlwave-shell-help-expression] or | |
910 | \\[idlwave-shell-mouse-help] with the mouse, or with a | |
911 | configureable set of custom examine commands using | |
912 | \\[idlwave-shell-examine-select]. The mouse examine commands can | |
913 | also work by click and drag, to select an expression for | |
914 | examination. | |
915 | ||
916 | 6. Hooks | |
8c7b4ec8 EZ |
917 | ----- |
918 | Turning on `idlwave-shell-mode' runs `comint-mode-hook' and | |
919 | `idlwave-shell-mode-hook' (in that order). | |
920 | ||
52a244eb | 921 | 7. Documentation and Customization |
8c7b4ec8 EZ |
922 | ------------------------------- |
923 | Info documentation for this package is available. Use \\[idlwave-info] | |
924 | to display (complain to your sysadmin if that does not work). | |
925 | For Postscript and HTML versions of the documentation, check IDLWAVE's | |
5e72c6b2 | 926 | homepage at `http://idlwave.org'. |
8c7b4ec8 EZ |
927 | IDLWAVE has customize support - see the group `idlwave'. |

1767 | We need to work hard here to remove the stupid line breaks inserted by | |
1768 | IDL5. These line breaks can be right in the middle of procedure | |
1769 | or file names. | |
1770 | It is very difficult to come up with a robust solution. This one seems | |
3938cb82 | 1771 | to be pretty good though. |
8c7b4ec8 EZ |
1772 | |
1773 | Here is in what ways it improves over the previous solution: | |
1774 | ||
1775 | 1. The procedure name can be split and will be restored. | |
1776 | 2. The number can be split. I have never seen this, but who knows. | |
1777 | 3. We do not require the `.pro' extension for files. | |
1778 | ||
1779 | This function can still break when the file name ends on a end line | |
1780 | and the message line contains an additional line with garbage. Then | |
1781 | the first part of that garbage will be added to the file name. | |
1782 | However, the function checks the existence of the files with and | |
1783 | without this last part - thus the function only breaks if file name | |
1784 | plus garbage match an existing regular file. This is hopefully very | |
52a244eb S |
