26 ;; Completion of tags by name using tables of semantic generated tags.
28 ;; While it would be a simple matter of flattening all tag known
29 ;; tables to perform completion across them using `all-completions',
30 ;; or `try-completion', that process would be slow. In particular,
31 ;; when a system database is included in the mix, the potential for a
32 ;; ludicrous number of options becomes apparent.
34 ;; As such, dynamically searching across tables using a prefix,
35 ;; regular expression, or other feature is needed to help find symbols
36 ;; quickly without resorting to "show me every possible option now".
38 ;; In addition, some symbol names will appear in multiple locations.
39 ;; If it is important to distiguish, then a way to provide a choice
40 ;; over these locations is important as well.
42 ;; Beyond brute force offers for completion of plain strings,
43 ;; using the smarts of semantic-analyze to provide reduced lists of
44 ;; symbols, or fancy tabbing to zoom into files to show multiple hits
45 ;; of the same name can be provided.
49 ;; There are several parts of any completion engine. They are:
51 ;; A. Collection of possible hits
52 ;; B. Typing or selecting an option
53 ;; C. Displaying possible unique completions
54 ;; D. Using the result
56 ;; Here, we will treat each section separately (excluding D)
57 ;; They can then be strung together in user-visible commands to
58 ;; fullfill specific needs.
62 ;; A collector is an object which represents the means by which tags
63 ;; to complete on are collected. It's first job is to find all the
64 ;; tags which are to be completed against. It can also rename
65 ;; some tags if needed so long as `semantic-tag-clone' is used.
67 ;; Some collectors will gather all tags to complete against first
68 ;; (for in buffer queries, or other small list situations). It may
69 ;; choose to do a broad search on each completion request. Built in
70 ;; functionality automatically focuses the cache in as the user types.
72 ;; A collector choosing to create and rename tags could choose a
73 ;; plain name format, a postfix name such as method:class, or a
74 ;; prefix name such as class.method.
78 ;; A displayor is in charge if showing the user interesting things
79 ;; about available completions, and can optionally provide a focus.
80 ;; The simplest display just lists all available names in a separate
81 ;; window. It may even choose to show short names when there are
82 ;; many to choose from, or long names when there are fewer.
84 ;; A complex displayor could opt to help the user 'focus' on some
85 ;; range. For example, if 4 tags all have the same name, subsequent
86 ;; calls to the displayor may opt to show each tag one at a time in
87 ;; the buffer. When the user likes one, selection would cause the
88 ;; 'focus' item to be selected.
92 ;; The format of the tag lists used to perform the completions are in
93 ;; semanticdb "find" format, like this:
95 ;; ( ( DBTABLE1 TAG1 TAG2 ...)
96 ;; ( DBTABLE2 TAG1 TAG2 ...)
99 ;; INLINE vs MINIBUFFER
101 ;; Two major ways completion is used in Emacs is either through a
102 ;; minibuffer query, or via completion in a normal editing buffer,
103 ;; encompassing some small range of characters.
105 ;; Structure for both types of completion are provided here.
106 ;; `semantic-complete-read-tag-engine' will use the minibuffer.
107 ;; `semantic-complete-inline-tag-engine' will complete text in
