27 | ;;; Commentary: | |
23b747d1 SM |
28 | ;; This mode is a major mode for editing Ada code. This is a major |
29 | ;; rewrite of the file packaged with Emacs-20. The Ada mode is | |
30 | ;; composed of four Lisp files: ada-mode.el, ada-xref.el, ada-prj.el | |
31 | ;; and ada-stmt.el. Only this file (ada-mode.el) is completely | |
32 | ;; independent from the GNU Ada compiler GNAT, distributed by Ada | |
33 | ;; Core Technologies. All the other files rely heavily on features | |
34 | ;; provided only by GNAT. | |
35 | ;; | |
36 | ;; Note: this mode will not work with Emacs 19. If you are on a VMS | |
37 | ;; system, where the latest version of Emacs is 19.28, you will need | |
38 | ;; another file, called ada-vms.el, that provides some required | |
39 | ;; functions. | |
7749c1a8 GM |
40 | |
41 | ;;; Usage: | |
23b747d1 SM |
42 | ;; Emacs should enter Ada mode automatically when you load an Ada file. |
43 | ;; By default, the valid extensions for Ada files are .ads, .adb or .ada | |
44 | ;; If the ada-mode does not start automatically, then simply type the | |
45 | ;; following command : | |
46 | ;; M-x ada-mode | |
47 | ;; | |
48 | ;; By default, ada-mode is configured to take full advantage of the GNAT | |
49 | ;; compiler (the menus will include the cross-referencing features,...). | |
50 | ;; If you are using another compiler, you might want to set the following | |
51 | ;; variable in your .emacs (Note: do not set this in the ada-mode-hook, it | |
52 | ;; won't work) : | |
53 | ;; (setq ada-which-compiler 'generic) | |
54 | ;; | |
55 | ;; This mode requires find-file.el to be present on your system. | |

7749c1a8 | 57 | ;;; History: |
23b747d1 SM |
58 | ;; The first Ada mode for GNU Emacs was written by V. Broman in |
59 | ;; 1985. He based his work on the already existing Modula-2 mode. | |
60 | ;; This was distributed as ada.el in versions of Emacs prior to 19.29. | |
61 | ;; | |
62 | ;; Lynn Slater wrote an extensive Ada mode in 1989. It consisted of | |
63 | ;; several files with support for dired commands and other nice | |
64 | ;; things. It is currently available from the PAL | |
65 | ;; (wuarchive.wustl.edu:/languages/ada) as ada-mode-1.06a.tar.Z. | |
66 | ;; | |
67 | ;; The probably very first Ada mode (called electric-ada.el) was | |
68 | ;; written by Steven D. Litvintchouk and Steven M. Rosen for the | |
69 | ;; Gosling Emacs. L. Slater based his development on ada.el and | |
70 | ;; electric-ada.el. | |
71 | ;; | |
72 | ;; A complete rewrite by M. Heritsch and R. Ebert has been done. | |
73 | ;; Some ideas from the Ada mode mailing list have been | |
74 | ;; added. Some of the functionality of L. Slater's mode has not | |
75 | ;; (yet) been recoded in this new mode. Perhaps you prefer sticking | |
76 | ;; to his version. | |
77 | ;; | |
78 | ;; A complete rewrite for Emacs-20 / GNAT-3.11 has been done by Ada Core | |
79 | ;; Technologies. | |

98 | ;; Note: Every function in this package is compiler-independent. |
99 | ;; The names start with ada- | |
100 | ;; The variables that the user can edit can all be modified through | |
101 | ;; the customize mode. They are sorted in alphabetical order in this | |
102 | ;; file. | |
103 | ||
104 | ;; Supported packages. | |
105 | ;; This package supports a number of other Emacs modes. These other modes | |
106 | ;; should be loaded before the ada-mode, which will then setup some variables | |
107 | ;; to improve the support for Ada code. | |
108 | ;; Here is the list of these modes: | |
109 | ;; `which-function-mode': Display the name of the subprogram the cursor is | |
110 | ;; in in the mode line. | |
111 | ;; `outline-mode': Provides the capability to collapse or expand the code | |
112 | ;; for specific language constructs, for instance if you want to hide the | |
113 | ;; code corresponding to a subprogram | |
114 | ;; `align': This mode is now provided with Emacs 21, but can also be | |
115 | ;; installed manually for older versions of Emacs. It provides the | |
116 | ;; capability to automatically realign the selected region (for instance | |
117 | ;; all ':=', ':' and '--' will be aligned on top of each other. | |
118 | ;; `imenu': Provides a menu with the list of entities defined in the current | |
119 | ;; buffer, and an easy way to jump to any of them | |
120 | ;; `speedbar': Provides a separate file browser, and the capability for each | |
121 | ;; file to see the list of entities defined in it and to jump to them | |
122 | ;; easily | |
123 | ;; `abbrev-mode': Provides the capability to define abbreviations, which | |
124 | ;; are automatically expanded when you type them. See the Emacs manual. | |

826 | ;; buffer. Two syntax tables are created, depending on whether we want '_' | |
827 | ;; to be considered as part of a word or not. | |
828 | ;; Some characters may have multiple meanings depending on the context: | |
829 | ;; - ' is either the beginning of a constant character or an attribute | |
830 | ;; - # is either part of a based litteral or a gnatprep statement. | |
831 | ;; - " starts a string, but not if inside a constant character. | |
832 | ;; - ( and ) should be ignored if inside a constant character. | |
833 | ;; Thus their syntax property is changed automatically, and we can still use | |
834 | ;; the standard Emacs functions for sexp (see `ada-in-string-p') | |
835 | ;; | |

cf38dd42 | 838 | ;; changes via syntax-propertize-function. |
655880d2 GM |

840 | ;; on XEmacs, the `syntax-table' property does not exist and we have to use a | |

2039 | ;; - offset to indent from this position (can also be a symbol or a list | |
2040 | ;; that are evaluated) | |

2042 | ;; position plus whatever value the evaluation of the second element provides. | |

2044 | ;; indentation was calculated, by showing which variables were used. |
2045 | ;; | |
2046 | ;; The indentation itself is done in only one pass: first we try to guess in | |
2047 | ;; what context we are by looking at the following keyword or punctuation | |
2048 | ;; sign. If nothing remarkable is found, just try to guess the indentation | |
2049 | ;; based on previous lines. | |
2050 | ;; | |
2051 | ;; The relevant functions for indentation are: | |
2052 | ;; - `ada-indent-region': Re-indent a region of text | |
2053 | ;; - `ada-justified-indent-current': Re-indent the current line and shows the | |
2054 | ;; calculation that were done | |
2055 | ;; - `ada-indent-current': Re-indent the current line | |
2056 | ;; - `ada-get-current-indent': Calculate the indentation for the current line, | |
2057 | ;; based on the context (see above). | |
2058 | ;; - `ada-get-indent-*': Calculate the indentation in a specific context. | |
