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

7749c1a8 | 56 | ;;; History: |
23b747d1 SM |
57 | ;; The first Ada mode for GNU Emacs was written by V. Broman in |
58 | ;; 1985. He based his work on the already existing Modula-2 mode. | |
59 | ;; This was distributed as ada.el in versions of Emacs prior to 19.29. | |
60 | ;; | |
61 | ;; Lynn Slater wrote an extensive Ada mode in 1989. It consisted of | |
62 | ;; several files with support for dired commands and other nice | |
63 | ;; things. It is currently available from the PAL | |
64 | ;; (wuarchive.wustl.edu:/languages/ada) as ada-mode-1.06a.tar.Z. | |
65 | ;; | |
66 | ;; The probably very first Ada mode (called electric-ada.el) was | |
67 | ;; written by Steven D. Litvintchouk and Steven M. Rosen for the | |
68 | ;; Gosling Emacs. L. Slater based his development on ada.el and | |
69 | ;; electric-ada.el. | |
70 | ;; | |
71 | ;; A complete rewrite by M. Heritsch and R. Ebert has been done. | |
72 | ;; Some ideas from the Ada mode mailing list have been | |
73 | ;; added. Some of the functionality of L. Slater's mode has not | |
74 | ;; (yet) been recoded in this new mode. Perhaps you prefer sticking | |
75 | ;; to his version. | |
76 | ;; | |
77 | ;; A complete rewrite for Emacs-20 / GNAT-3.11 has been done by Ada Core | |
78 | ;; Technologies. | |

97 | ;; Note: Every function in this package is compiler-independent. |
98 | ;; The names start with ada- | |
99 | ;; The variables that the user can edit can all be modified through | |
100 | ;; the customize mode. They are sorted in alphabetical order in this | |
101 | ;; file. | |
102 | ||
103 | ;; Supported packages. | |
104 | ;; This package supports a number of other Emacs modes. These other modes | |
105 | ;; should be loaded before the ada-mode, which will then setup some variables | |
106 | ;; to improve the support for Ada code. | |
107 | ;; Here is the list of these modes: | |
37269466 | 108 | ;; `which-function-mode': Display in the mode line the name of the subprogram |
58179cce | 109 | ;; the cursor is in. |
23b747d1 SM |
110 | ;; `outline-mode': Provides the capability to collapse or expand the code |
111 | ;; for specific language constructs, for instance if you want to hide the | |
112 | ;; code corresponding to a subprogram | |
113 | ;; `align': This mode is now provided with Emacs 21, but can also be | |
114 | ;; installed manually for older versions of Emacs. It provides the | |
115 | ;; capability to automatically realign the selected region (for instance | |
116 | ;; all ':=', ':' and '--' will be aligned on top of each other. | |
117 | ;; `imenu': Provides a menu with the list of entities defined in the current | |
118 | ;; buffer, and an easy way to jump to any of them | |
119 | ;; `speedbar': Provides a separate file browser, and the capability for each | |
120 | ;; file to see the list of entities defined in it and to jump to them | |
121 | ;; easily | |
122 | ;; `abbrev-mode': Provides the capability to define abbreviations, which | |
123 | ;; are automatically expanded when you type them. See the Emacs manual. | |

820 | ;; buffer. Two syntax tables are created, depending on whether we want '_' | |
821 | ;; to be considered as part of a word or not. | |
822 | ;; Some characters may have multiple meanings depending on the context: | |
823 | ;; - ' is either the beginning of a constant character or an attribute | |
53964682 | 824 | ;; - # is either part of a based literal or a gnatprep statement. |
655880d2 GM |
825 | ;; - " starts a string, but not if inside a constant character. |
826 | ;; - ( and ) should be ignored if inside a constant character. | |
827 | ;; Thus their syntax property is changed automatically, and we can still use | |
828 | ;; the standard Emacs functions for sexp (see `ada-in-string-p') | |

655880d2 GM |

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

2027 | ;; - offset to indent from this position (can also be a symbol or a list | |
2028 | ;; that are evaluated) | |

2030 | ;; position plus whatever value the evaluation of the second element provides. | |

655880d2 GM |
2032 | ;; indentation was calculated, by showing which variables were used. |
2033 | ;; | |
2034 | ;; The indentation itself is done in only one pass: first we try to guess in | |
2035 | ;; what context we are by looking at the following keyword or punctuation | |
2036 | ;; sign. If nothing remarkable is found, just try to guess the indentation | |
2037 | ;; based on previous lines. | |
2038 | ;; | |
2039 | ;; The relevant functions for indentation are: | |
2040 | ;; - `ada-indent-region': Re-indent a region of text | |
2041 | ;; - `ada-justified-indent-current': Re-indent the current line and shows the | |
2042 | ;; calculation that were done | |
2043 | ;; - `ada-indent-current': Re-indent the current line | |
2044 | ;; - `ada-get-current-indent': Calculate the indentation for the current line, | |
2045 | ;; based on the context (see above). | |
2046 | ;; - `ada-get-indent-*': Calculate the indentation in a specific context. | |
