30 ;; Fast search for selected org nodes and things outside of org.
32 ;; org-index creates and updates an index table with keywords; each line
33 ;; either points to a heading in org, references something outside or
34 ;; carries a snippet of text to yank. When searching the index, the set
35 ;; of matching lines is updated with every keystroke; results are sorted
36 ;; by usage count and date, so that frequently used entries appear first
37 ;; in the list of results.
39 ;; References are decorated numbers (e.g. 'R237' or '--455--'); they are
40 ;; well suited to be used outside of org, e.g. in folder names, ticket
41 ;; systems or on printed documents.
43 ;; On first invocation org-index will assist you in creating the index
46 ;; To start using your index, invoke subcommands 'add', 'ref' and 'yank'
47 ;; to create entries and 'occur' to find them.
52 ;; - Place this file in a directory of your load-path,
53 ;; e.g. org-mode/contrib/lisp.
54 ;; - Add these lines to your .emacs:
56 ;; (require 'org-index)
58 ;; - Restart your Emacs to make this effective.
59 ;; - Invoke `org-index'; on first run it will assist in creating your
62 ;; - Optionally invoke `M-x org-customize', group 'Org Index', to tune
63 ;; some settings, e.g. the global prefix key 'C-c i'.
66 ;; Further information:
68 ;; - Watch the screencast at http://2484.de/org-index.html.
69 ;; - See the documentation of `org-index', which can also be read by

305 "Fast search-index for selected org nodes and things outside.
307 This function creates and updates an index table with keywords;
308 each line either points to a heading in org, references something
309 outside or carries a snippet of text to yank. The index table is
310 searched for keywords by means of an incremental occur; results
311 are sorted by usage count and date, so that frequently used
312 entries appear first.
314 References are decorated numbers (e.g. 'R237' or '--455--'); they are
315 well suited to be used outside of org, e.g. in folder names, ticket
316 systems or on printed documents.
318 On first invocation this function will help to create a dedicated node
321 To start building up your index, use subcommands 'add', 'ref' and
322 'yank' to create entries and use 'occur' to find them.
324 This is version 5.7.2 of org-index.el.
327 The function `org-index' is the only interactive function of this
328 package and its main entry point; it will present you with a list
329 of subcommands to choose from:
331 \(Note the one-letter shortcuts, e.g. [o]; used like `\\[org-index-dispatch] o'.)
333 occur: [o] Incrementally show matching lines from index.
334 Result is updated after every keystroke. You may enter a
335 list of words seperated by space or comma (`,'), to select
336 lines that contain all of the given words. With a numeric
337 prefix argument, show lines, which have been accessed at
338 most this many days ago.
340 add: [a] Add the current node to index.
341 So that (e.g.) it can be found through the subcommand
342 'occur'. Update index, if node is already present.
344 kill: [k] Kill (delete) the current node from index.
345 Can be invoked from index, from occur or from a headline.
347 head: [h] Search for heading, by ref or from index line.
348 If invoked from within index table, go to associated
349 node (if any), otherwise ask for ref to search.
351 index: [i] Enter index table and maybe go to a specific reference.
352 Use `org-mark-ring-goto' (\\[org-mark-ring-goto]) to go back.
354 ping: [p] Echo line from index table for current node.
355 If current node is not in index, than search among its
358 ref: [r] Create a new index line with a reference.
359 This line will not be associated with a node.
361 yank: [y] Store a new string, that can be yanked from occur.
362 The index line will not be associated with a node.
364 column: [c] From within index table: read char and jump to column.
365 Shortcut for column movement; stays within one index line.
367 edit: [e] Present current line in edit buffer.
368 Can be invoked from index, from occur or from a headline.
370 focus: [f] Return to first focused node; repeat to see them all.
371 The focused nodes are kept in a short list; they need not be
372 part of the index though. This command visits one focus node
373 after the other, as long as you invoke it in quick succession
374 and without moving to other nodes; otherwise it returns to
375 the focus node, where you left off. Finally, with a prefix
376 argument, this command offers more options, e.g. to set focus
379 help: Show complete help text of `org-index'.
382 short-help: [?] Show this one-line description of each subcommand.
383 I.e. from the complete help, show only the first line for each
386 news: [n] Show news for the current point release.
388 example: Create an example index, that will not be saved.
389 May serve as an example.
391 sort: Sort lines in index, in region or buffer.
392 Region or buffer can be sorted by contained reference; Index
393 by count, reference or last access.
395 find-ref: Search for given reference in all org-buffers.
396 A wrapper to employ Emacs standard `multi-occur' function;
399 highlight: Highlight or unhighlight all references.
400 Operates on active region or whole buffer. Call with prefix
401 argument (`C-u') to remove highlights.
403 maintain: Index maintainance.
404 Offers some choices to check, update or fix your index.
406 If you invoke `org-index' for the first time, an assistant will be
407 invoked, that helps you to create your own index.
409 Invoke `org-customize' to tweak the behaviour of `org-index'.
411 This includes the global key `org-index-dispatch-key' to invoke
412 the most important subcommands with one additional key.
414 A numeric prefix argument is used as a reference number for
415 commands, that need one (e.g. 'head') or to modify their
416 behaviour (e.g. 'occur').
418 Also, a single prefix argument may be specified just before the
419 final character (e.g. like `C-c i C-u f') or by just typing an
420 upper case letter (e.g. `C-c i F').
422 Use from elisp: Optional argument COMMAND is a symbol naming the
423 command to execute. SEARCH-REF specifies a reference to search
424 for, if needed. ARG allows passing in a prefix argument as in
427 (interactive "i\ni\nP")
