26 ;;; Commentary:
28 ;; This mode allows you to align regions in a context-sensitive fashion.
29 ;; The classic use is to align assignments:
30 ;;
31 ;; int a = 1;
32 ;; short foo = 2;
33 ;; double blah = 4;
34 ;;
35 ;; becomes
36 ;;
37 ;; int a = 1;
38 ;; short foo = 2;
39 ;; double blah = 4;
41 ;;; Usage:
43 ;; There are several variables which define how certain "categories"
44 ;; of syntax are to be treated. These variables go by the name
45 ;; `align-CATEGORY-modes'. For example, "c++" is such a category.
46 ;; There are several rules which apply to c++, but since several other
47 ;; languages have a syntax similar to c++ (e.g., c, java, etc), these
48 ;; modes are treated as belonging to the same category.
49 ;;
50 ;; If you want to add a new mode under a certain category, just
51 ;; customize that list, or add the new mode manually. For example, to
52 ;; make jde-mode a c++ category mode, use this code in your .emacs
53 ;; file:
54 ;;
55 ;; (setq align-c++-modes (cons 'jde-mode align-c++-modes))
57 ;; In some programming modes, it's useful to have the aligner run only
58 ;; after indentation is performed. To achieve this, customize or set
59 ;; the variable `align-indent-before-aligning' to t.
61 ;;; Module Authors:
63 ;; In order to incorporate align's functionality into your own
64 ;; modules, there are only a few steps you have to follow.
66 ;; 1. Require or load in the align.el library.
67 ;;
68 ;; 2. Define your alignment and exclusion rules lists, either
69 ;; customizable or not.
70 ;;
71 ;; 3. In your mode function, set the variables
72 ;; `align-mode-rules-list' and `align-mode-exclude-rules-list'
73 ;; to your own rules lists.
75 ;; If there is any need to add your mode name to one of the
76 ;; align-?-modes variables (for example, `align-dq-string-modes'), use
77 ;; `add-to-list', or some similar function which checks first to see
78 ;; if the value is already there. Since the user may customize that
79 ;; mode list, and then write your mode name into their .emacs file,
80 ;; causing the symbol already to be present the next time they load
81 ;; your package.
83 ;; Example:
84 ;;
85 ;; (require 'align)
86 ;;
87 ;; (defcustom my-align-rules-list
88 ;; '((my-rule
89 ;; (regexp . "Sample")))
90 ;; :type align-rules-list-type
91 ;; :group 'my-package)
92 ;;
93 ;; (put 'my-align-rules-list 'risky-local-variable t)
94 ;;
95 ;; (add-to-list 'align-dq-string-modes 'my-package-mode)
96 ;; (add-to-list 'align-open-comment-modes 'my-package-mode)
97 ;;
98 ;; (defun my-mode ()
99 ;; ...
100 ;; (setq align-mode-rules-list my-align-rules-list))
101 ;;
102 ;; Note that if you need to install your own exclusion rules, then you
103 ;; will also need to reproduce any double-quoted string, or open
104 ;; comment exclusion rules that are defined in the standard
105 ;; `align-exclude-rules-list'. At the moment there is no convenient
106 ;; way to mix both mode-local and global rules lists.
108 ;;; History:
110 ;; Version 1.0 was created in the earlier part of 1996, using a very
111 ;; simple algorithm that understand only basic regular expressions.
112 ;; Parts of the code were broken up and included in vhdl-mode.el
113 ;; around this time. After several comments from users, and a need to
114 ;; find a more robust, performant algorithm, 2.0 was born in late
115 ;; 1998. Many different approaches were taken (mostly due to the
116 ;; complexity of TeX tables), but finally a scheme was discovered
117 ;; which worked fairly well for most common usage cases. Development
118 ;; beyond version 2.8 is not planned, except for problems that users
119 ;; might encounter.
121 ;;; Code:
124 "Align text to a specific column, by regexp."
128 ;;; User Variables:
131 "*Hook that gets run after the aligner has been loaded."
136 "*If non-nil, indent the marked region before aligning it."
141 "*An integer that represents the default amount of padding to use.
142 If `align-to-tab-stop' is non-nil, this will represent the number of
143 tab stops to use for alignment, rather than the number of spaces.
144 Each alignment rule can optionally override both this variable. See
145 `align-mode-alist'."
150 "*If non-nil, alignments will always fall on a tab boundary.
151 It may also be a symbol, whose value will be taken."
156 "*If non-nil, used as a heuristic by `align-current'.
157 Since each alignment rule can possibly have its own set of alignment
158 sections (whenever `align-region-separate' is non-nil, and not a
159 string), this heuristic is used to determine how far before and after
160 point we should search in looking for a region separator. Larger
161 values can mean slower perform in large files, although smaller values
162 may cause unexpected behavior at times."
167 "*The face to highlight with if changes are necessary."
172 "*The face to highlight with if no changes are necessary."
178 If nil,then no messages will ever be printed to the minibuffer."
183 "*A list of modes whose syntax resembles C/C++."
188 "*A list of modes where perl syntax is to be seen."
194 "*A list of modes whose syntax resembles Lisp."
200 "*A list of modes whose syntax resembles TeX (and family)."
205 "*A list of modes whose content is plain text."
212 "*A list of modes where double quoted strings should be excluded."
218 "*A list of modes where single quoted strings should be excluded."
225 "*A list of modes with a single-line comment syntax.
226 These are comments as in Lisp, which have a beginning but, end with
227 the line (i.e., `comment-end' is an empty string)."
232 "*Select the method by which alignment sections will be separated.
233 If this is a symbol, that symbol's value will be used.
235 For the sake of clarification, consider the following example, which
236 will be referred to in the descriptions below.
238 int alpha = 1; /* one */
239 double beta = 2.0;
240 long gamma; /* ten */
242 unsigned int delta = 1; /* one */
243 long double epsilon = 3.0;
244 long long omega; /* ten */
246 The possible settings for `align-region-separate' are:
248 `entire' The entire region being aligned will be considered as a
249 single alignment section. Assuming that comments were not
250 being aligned to a particular column, the example would
251 become:
253 int alpha = 1; /* one */
254 double beta = 2.0;
255 long gamma; /* ten */
257 unsigned int delta = 1; /* one */
258 long double epsilon;
259 long long chi = 10; /* ten */
261 `group' Each contiguous set of lines where a specific alignment
262 occurs is considered a section for that alignment rule.
263 Note that each rule will may have any entirely different
264 set of section divisions than another.
266 int alpha = 1; /* one */
267 double beta = 2.0;
268 long gamma; /* ten */
270 unsigned int delta = 1; /* one */
271 long double epsilon;
272 long long chi = 10; /* ten */
274 `largest' When contiguous rule sets overlap, the largest section
275 described will be taken as the alignment section for each
276 rule touched by that section.
278 int alpha = 1; /* one */
279 double beta = 2.0;
280 long gamma; /* ten */
282 unsigned int delta = 1; /* one */
283 long double epsilon;
284 long long chi = 10; /* ten */
286 NOTE: This option is not supported yet, due to algorithmic
287 issues which haven't been satisfactorily resolved. There
288 are ways to do it, but they're both ugly and resource
289 consumptive.
291 regexp A regular expression string which defines the section
292 divider. If the mode you're in has a consistent divider
293 between sections, the behavior will be very similar to
294 `largest', and faster. But if the mode does not use clear
295 separators (for example, if you collapse your braces onto
296 the preceding statement in C or perl), `largest' is
297 probably the better alternative.
299 function A function that will be passed the beginning and ending
300 locations of the region in which to look for the section
301 separator. At the very beginning of the attempt to align,
302 both of these parameters will be nil, in which case the
303 function should return non-nil if it wants each rule to
304 define its own section, or nil if it wants the largest
305 section found to be used as the common section for all rules
306 that occur there.
308 list A list of markers within the buffer that represent where
309 the section dividers lie. Be certain to use markers! For
310 when the aligning begins, the ensuing contract/expanding of
311 whitespace will throw off any non-marker positions.
313 This method is intended for use in Lisp programs, and not
314 by the user."

585 "*A list describing all of the available alignment rules.
586 The format is:
588 ((TITLE
589 (ATTRIBUTE . VALUE) ...)
590 ...)
592 The following attributes are meaningful:
594 `regexp' This required attribute must be either a string describing
595 a regular expression, or a function (described below).
596 For every line within the section that this regular
597 expression matches, the given rule will be applied to that
598 line. The exclusion rules denote which part(s) of the
599 line should not be modified; the alignment rules cause the
600 identified whitespace group to be contracted/expanded such
602 immediately following the identified parenthesis group),
603 occurs in the same column for every line within the
604 alignment section (see `align-region-separate' for a
605 description of how the region is broken up into alignment
606 sections).
608 The `regexp' attribute describes how the text should be
609 treated. Within this regexp, there must be at least one
610 group of characters (typically whitespace) identified by
611 the special opening and closing parens used in regexp
613 the syntax of regular expressions for more info).
615 If `regexp' is a function, it will be called as a
616 replacement for `re-search-forward'. This means that it
617 should return nil if nothing is found to match the rule,
618 or it should set the match data appropriately, move point
619 to the end of the match, and return the value of point.
621 `group' For exclusion rules, the group identifies the range of
622 characters that should be ignored. For alignment rules,
623 these are the characters that will be deleted/expanded for
625 always the first character immediately following this
626 parenthesis group. This attribute may also be a list of
627 integer, in which case multiple alignment characters will
628 be aligned, with the list of integer identifying the
629 whitespace groups which precede them. The default for
630 this attribute is 1.
632 `modes' The `modes' attribute, if set, should name a list of
633 major modes -- or evaluate to such a value -- in which the
634 rule is valid. If not set, the rule will apply to all
635 modes.
637 `case-fold' If `regexp' is an ordinary regular expression string
638 containing alphabetic character, sometimes you may want
639 the search to proceed case-insensitively (for languages
640 that ignore case, such as pascal for example). In that
641 case, set `case-fold' to a non-nil value, and the regular
642 expression search will ignore case. If `regexp' is set to
643 a function, that function must handle the job of ignoring
644 case by itself.
646 `tab-stop' If the `tab-stop' attribute is set, and non-nil, the
647 alignment character will always fall on a tab stop
648 (whether it uses tabs to get there or not depends on the
649 value of `indent-tabs-mode'). If the `tab-stop' attribute
650 is set to nil, tab stops will never be used. Otherwise,
651 the value of `align-to-tab-stop' determines whether or not
652 to align to a tab stop. The `tab-stop' attribute may also
653 be a list of t or nil values, corresponding to the number
654 of parenthesis groups specified by the `group' attribute.
656 `repeat' If the `repeat' attribute is present, and non-nil, the
657 rule will be applied to the line continuously until no
658 further matches are found.
660 `valid' If the `valid' attribute is set, it will be used to
661 determine whether the rule should be invoked. This form
662 is evaluated after the regular expression match has been
663 performed, so that it is possible to use the results of
664 that match to determine whether the alignment should be
665 performed. The buffer should not be modified during the
666 evaluation of this form.
668 `run-if' Like `valid', the `run-if' attribute tests whether the
669 rule should be run at all -- even before any searches are
670 done to determine if the rule applies to the alignment
671 region. This can save time, since `run-if' will only be
672 run once for each rule. If it returns nil, the rule will
673 not be attempted.
675 `column' For alignment rules, if the `column' attribute is set --
676 which must be an integer, or a symbol whose value is an
677 integer -- it will be used as the column in which to align
678 the alignment character. If the text on a particular line
679 happens to overrun that column, a single space character,
680 or tab stop (see `align-to-tab-stop') will be added
681 between the last text character and the alignment
682 character.
684 `spacing' Alignment rules may also override the amount of spacing
685 that would normally be used by providing a `spacing'
686 attribute. This must be an integer, or a list of integers
687 corresponding to the number of parenthesis groups matched
688 by the `group' attribute. If a list of value is used, and
689 any of those values is nil, `align-default-spacing' will
690 be used for that subgroup. See `align-default-spacing'
691 for more details on spacing, tab stops, and how to
692 indicate how much spacing should be used. If TAB-STOP is
693 present, it will override the value of `align-to-tab-stop'
694 for that rule.
696 `justify' It is possible with `regexp' and `group' to identify a
697 character group that contains more than just whitespace
698 characters. By default, any non-whitespace characters in
699 that group will also be deleted while aligning the
700 alignment character. However, if the `justify' attribute
701 is set to a non-nil value, only the initial whitespace
702 characters within that group will be deleted. This has
703 the effect of right-justifying the characters that remain,
704 and can be used for outdenting or just plain old right-
705 justification.
707 `separate' Each rule can define its own section separator, which
709 within the region to be aligned. Setting the `separate'
710 attribute overrides the value of `align-region-separate'
711 (see the documentation of that variable for possible
712 values), and any separation argument passed to `align'."
