30 | ;;; Commentary: | |
31 | ;;; This mode is a major mode for editing Ada83 and Ada95 source code. | |
4cc7e498 | 32 | ;;; This is a major rewrite of the file packaged with Emacs-20. The |
f7a80909 | 33 | ;;; ada-mode is composed of four lisp files, ada-mode.el, ada-xref.el, |
6d533a6e | 34 | ;;; ada-prj.el and ada-stmt.el. Only this file (ada-mode.el) is |
655880d2 | 35 | ;;; completely independent from the GNU Ada compiler Gnat, distributed |
6d533a6e | 36 | ;;; by Ada Core Technologies. All the other files rely heavily on |
5dab0769 | 37 | ;;; features provided only by Gnat. |
972579f9 | 38 | ;;; |
7749c1a8 GM |
39 | ;;; Note: this mode will not work with Emacs 19. If you are on a VMS |
40 | ;;; system, where the latest version of Emacs is 19.28, you will need | |
41 | ;;; another file, called ada-vms.el, that provides some required | |
42 | ;;; functions. | |
43 | ||
44 | ;;; Usage: | |
45 | ;;; Emacs should enter Ada mode automatically when you load an Ada file. | |
46 | ;;; By default, the valid extensions for Ada files are .ads, .adb or .ada | |
47 | ;;; If the ada-mode does not start automatically, then simply type the | |
48 | ;;; following command : | |
49 | ;;; M-x ada-mode | |
50 | ;;; | |
51 | ;;; By default, ada-mode is configured to take full advantage of the GNAT | |
52 | ;;; compiler (the menus will include the cross-referencing features,...). | |
53 | ;;; If you are using another compiler, you might want to set the following | |
54 | ;;; variable in your .emacs (Note: do not set this in the ada-mode-hook, it | |
55 | ;;; won't work) : | |
56 | ;;; (setq ada-which-compiler 'generic) | |
57 | ;;; | |
58 | ;;; This mode requires find-file.el to be present on your system. | |
972579f9 | 59 | |
7749c1a8 | 60 | ;;; History: |
3ca7b46f KH |
61 | ;;; The first Ada mode for GNU Emacs was written by V. Broman in |
62 | ;;; 1985. He based his work on the already existing Modula-2 mode. | |
63 | ;;; This was distributed as ada.el in versions of Emacs prior to 19.29. | |
972579f9 RS |
64 | ;;; |
65 | ;;; Lynn Slater wrote an extensive Ada mode in 1989. It consisted of | |
66 | ;;; several files with support for dired commands and other nice | |
67 | ;;; things. It is currently available from the PAL | |
68 | ;;; (wuarchive.wustl.edu:/languages/ada) as ada-mode-1.06a.tar.Z. | |
69 | ;;; | |
70 | ;;; The probably very first Ada mode (called electric-ada.el) was | |
71 | ;;; written by Steven D. Litvintchouk and Steven M. Rosen for the | |
72 | ;;; Gosling Emacs. L. Slater based his development on ada.el and | |
73 | ;;; electric-ada.el. | |
74 | ;;; | |
7749c1a8 GM |
75 | ;;; A complete rewrite by M. Heritsch and R. Ebert has been done. |
76 | ;;; Some ideas from the Ada mode mailing list have been | |
972579f9 RS |
77 | ;;; added. Some of the functionality of L. Slater's mode has not |
78 | ;;; (yet) been recoded in this new mode. Perhaps you prefer sticking | |
79 | ;;; to his version. | |
972579f9 | 80 | ;;; |
7749c1a8 GM |
81 | ;;; A complete rewrite for Emacs-20 / Gnat-3.11 has been done by Ada Core |
82 | ;;; Technologies. Please send bugs to briot@gnat.com | |

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

789 | ;; Grammar related function | |
790 | ;; The functions below work with the syntax class of the characters in an Ada | |
791 | ;; buffer. Two syntax tables are created, depending on whether we want '_' | |
792 | ;; to be considered as part of a word or not. | |
793 | ;; Some characters may have multiple meanings depending on the context: | |
794 | ;; - ' is either the beginning of a constant character or an attribute | |
795 | ;; - # is either part of a based litteral or a gnatprep statement. | |
796 | ;; - " starts a string, but not if inside a constant character. | |
797 | ;; - ( and ) should be ignored if inside a constant character. | |
798 | ;; Thus their syntax property is changed automatically, and we can still use | |
799 | ;; the standard Emacs functions for sexp (see `ada-in-string-p') | |
800 | ;; | |
801 | ;; On Emacs, this is done through the `syntax-table' text property. The | |
802 | ;; modification is done automatically each time the user as typed a new | |
803 | ;; character. This is already done in `font-lock-mode' (in | |
804 | ;; `font-lock-syntactic-keywords', so we take advantage of the existing | |
805 | ;; mechanism. If font-lock-mode is not activated, we do it by hand in | |
806 | ;; `ada-after-change-function', thanks to `ada-deactivate-properties' and | |
807 | ;; `ada-initialize-properties'. | |
808 | ;; | |
809 | ;; on XEmacs, the `syntax-table' property does not exist and we have to use a | |
810 | ;; slow advice to `parse-partial-sexp' to do the same thing. | |
811 | ;; When executing parse-partial-sexp, we simply modify the strings before and | |
812 | ;; after, so that the special constants '"', '(' and ')' do not interact | |
813 | ;; with parse-partial-sexp. | |
814 | ;; Note: this code is slow and needs to be rewritten as soon as something | |
815 | ;; better is available on XEmacs. | |

1421 | ;; auto-casing | |
1422 | ;; Since Ada is case-insensitive, the Ada-mode provides an extensive set of | |
1423 | ;; functions to auto-case identifiers, keywords, ... | |
1424 | ;; The basic rules for autocasing are defined through the variables | |
1425 | ;; `ada-case-attribute', `ada-case-keyword' and `ada-case-identifier'. These | |
1426 | ;; are references to the functions that will do the actual casing. | |
1427 | ;; | |
1428 | ;; However, in most cases, the user will want to define some exceptions to | |
1429 | ;; these casing rules. This is done through a list of files, that contain | |
1430 | ;; one word per line. These files are stored in `ada-case-exception-file'. | |
4cc7e498 | 1431 | ;; For backward compatibility, this variable can also be a string. |

2119 | ;; All indentations are indicated as a two-element string: | |
2120 | ;; - position of reference in the buffer | |
2121 | ;; - offset to indent from this position (can also be a symbol or a list | |
2122 | ;; that are evaluated) | |
2123 | ;; Thus the total indentation for a line is the column number of the reference | |
2124 | ;; position plus whatever value the evaluation of the second element provides. | |
2125 | ;; This mechanism is used so that the ada-mode can "explain" how the | |
2126 | ;; indentation was calculated, by showing which variables were used. | |
2127 | ;; | |
2128 | ;; The indentation itself is done in only one pass: first we try to guess in | |
2129 | ;; what context we are by looking at the following keyword or punctuation | |
2130 | ;; sign. If nothing remarkable is found, just try to guess the indentation | |
2131 | ;; based on previous lines. | |
2132 | ;; | |
2133 | ;; The relevant functions for indentation are: | |
2134 | ;; - `ada-indent-region': Re-indent a region of text | |
2135 | ;; - `ada-justified-indent-current': Re-indent the current line and shows the | |
2136 | ;; calculation that were done | |
2137 | ;; - `ada-indent-current': Re-indent the current line | |
2138 | ;; - `ada-get-current-indent': Calculate the indentation for the current line, | |
2139 | ;; based on the context (see above). | |
