;;
;;; Change Log:
;;
-;; 2013-03-19 (0.6)
-;; Switching between tag files now works correctly with `company-etags'.
-;; Clang completions now include macros and are case-sensitive.
-;; Added `company-capf': completion adapter using
-;; `completion-at-point-functions'. (Stefan Monnier)
-;; `company-elisp' has some improvements.
-;; Instead of `overrriding-terminal-local-map', we're now using
-;; `emulation-mode-map-alists' (experimental). This largely means that when
-;; the completion keymap is active, other minor modes' keymaps are still
-;; used, so, for example, it's not as easy to circumvent `paredit-mode'
-;; accidentally when it's enabled.
-;; Fixed two old tooltip annoyances.
-;; Some performance improvements.
-;; `company-clang' now shows meta information, too.
-;; Candidates from grouped back-ends are merged more conservatively: only
-;; back-ends that return the same prefix at point are used.
-;; Loading of `nxml', `semantic', `pymacs' and `ropemacs' is now deferred.
-;; `company-pysmell' is not used by default anymore.
-;; Across-the-board bugfixing.
-;;
-;; 2010-02-24 (0.5)
-;; `company-ropemacs' now provides location and docs. (Fernando H. Silva)
-;; Added `company-with-candidate-inserted' macro.
-;; Added `company-clang' back-end.
-;; Added new mechanism for non-consecutive insertion.
-;; (So far only used by clang for ObjC.)
-;; The semantic back-end now shows meta information for local symbols.
-;; Added compatibility for CEDET in Emacs 23.2 and from CVS. (Oleg Andreev)
-;;
-;; 2009-05-07 (0.4.3)
-;; Added `company-other-backend'.
-;; Idle completion no longer interrupts multi-key command input.
-;; Added `company-ropemacs' and `company-pysmell' back-ends.
-;;
-;; 2009-04-25 (0.4.2)
-;; In C modes . and -> now count towards `company-minimum-prefix-length'.
-;; Reverted default front-end back to `company-preview-if-just-one-frontend'.
-;; The pseudo tooltip will no longer be clipped at the right window edge.
-;; Added `company-tooltip-minimum'.
-;; Windows compatibility fixes.
-;;
-;; 2009-04-19 (0.4.1)
-;; Added `global-company-mode'.
-;; Performance enhancements.
-;; Added `company-eclim' back-end.
-;; Added safer workaround for Emacs `posn-col-row' bug.
-;;
-;; 2009-04-18 (0.4)
-;; Automatic completion is now aborted if the prefix gets too short.
-;; Added option `company-dabbrev-time-limit'.
-;; `company-backends' now supports merging back-ends.
-;; Added back-end `company-dabbrev-code' for generic code.
-;; Fixed `company-begin-with'.
-;;
-;; 2009-04-15 (0.3.1)
-;; Added 'stop prefix to prevent dabbrev from completing inside of symbols.
-;; Fixed issues with tabbar-mode and line-spacing.
-;; Performance enhancements.
-;;
-;; 2009-04-12 (0.3)
-;; Added `company-begin-commands' option.
-;; Added abbrev, tempo and Xcode back-ends.
-;; Back-ends are now interactive. You can start them with M-x backend-name.
-;; Added `company-begin-with' for starting company from elisp-code.
-;; Added hooks.
-;; Added `company-require-match' and `company-auto-complete' options.
-;;
-;; 2009-04-05 (0.2.1)
-;; Improved Emacs Lisp back-end behavior for local variables.
-;; Added `company-elisp-detect-function-context' option.
-;; The mouse can now be used for selection.
-;;
-;; 2009-03-22 (0.2)
-;; Added `company-show-location'.
-;; Added etags back-end.
-;; Added work-around for end-of-buffer bug.
-;; Added `company-filter-candidates'.
-;; More local Lisp variables are now included in the candidates.
-;;
-;; 2009-03-21 (0.1.5)
-;; Fixed elisp documentation buffer always showing the same doc.
-;; Added `company-echo-strip-common-frontend'.
-;; Added `company-show-numbers' option and M-0 ... M-9 default bindings.
-;; Don't hide the echo message if it isn't shown.
-;;
-;; 2009-03-20 (0.1)

"The list of active back-ends (completion engines).
-Each list elements can itself be a list of back-ends. In that case their
-completions are merged. Otherwise only the first matching back-end returns
-results.
+
+Only one back-end is used at a time. The choice depends on the order of
+the items in this list, and on the values they return in response to the
+`prefix' command (see below). But a back-end can also be a \"grouped\"
+one (see below).
`company-begin-backend' can be used to start a specific back-end,
`company-other-backend' will skip to the next matching back-end in the list.

-text immediately before `point'. Returning nil passes control to the next
-back-end. The function should return 'stop if it should complete but cannot
-\(e.g. if it is in the middle of a string\). If the returned value is only
-part of the prefix (e.g. the part after \"->\" in C), the back-end may return a
-cons of prefix and prefix length, which is then used in the
-`company-minimum-prefix-length' test.
+text immediately before point. Returning nil passes control to the next
+back-end. The function should return `stop' if it should complete but
+cannot (e.g. if it is in the middle of a string). Instead of a string,
+the back-end may return a cons where car is the prefix and cdr is used in
+`company-minimum-prefix-length' test. It must be either number or t, and
+in the latter case the test automatically succeeds.
`candidates': The second argument is the prefix to be completed. The
-return value should be a list of candidates that start with the prefix.
+return value should be a list of candidates that match the prefix.
+
+Non-prefix matches are also supported (candidates that don't start with the
+prefix, but match it in some backend-defined way). Backends that use this
+feature must disable cache (return t to `no-cache') and should also respond
+to `match'.
Optional commands:
-`sorted': The back-end may return t here to indicate that the candidates
-are sorted and will not need to be sorted again.
+`sorted': Return t here to indicate that the candidates are sorted and will
+not need to be sorted again.
`duplicates': If non-nil, company will take care of removing duplicates
from the list.

argument is the latest prefix.
-`meta': The second argument is a completion candidate. The back-end should
-return a (short) documentation string for it.
+`meta': The second argument is a completion candidate. Return a (short)
+documentation string for it.
+
+`doc-buffer': The second argument is a completion candidate. Return a
+buffer with documentation for it. Preferably use `company-doc-buffer',
-`doc-buffer': The second argument is a completion candidate.
-The back-end should create a buffer (preferably with `company-doc-buffer'),
-fill it with documentation and return it.
+`location': The second argument is a completion candidate. Return the cons
+of buffer and buffer location, or of file and line number where the
+completion candidate was defined.
-`location': The second argument is a completion candidate. The back-end can
-return the cons of buffer and buffer location, or of file and line
-number where the completion candidate was defined.
+`annotation': The second argument is a completion candidate. Return a
+string to be displayed inline with the candidate in the popup. If
+duplicates are removed by company, candidates with equal string values will
+be kept if they have different annotations. For that to work properly,
+backends should store the related information on candidates using text
+properties.
-`require-match': If this value is t, the user is not allowed to enter anything
-not offering as a candidate. Use with care! The default value nil gives the
-user that choice with `company-require-match'. Return value 'never overrides
-that option the other way around.
+`match': The second argument is a completion candidate. Backends that
+provide non-prefix completions should return the position of the end of
+text in the candidate that matches `prefix'. It will be used when
+rendering the popup.
+
+`require-match': If this returns t, the user is not allowed to enter
+anything not offered as a candidate. Use with care! The default value nil
+gives the user that choice with `company-require-match'. Return value
+`never' overrides that option the other way around.
+
+`init': Called once for each buffer. The back-end can check for external
+programs and files and load any required libraries. Raising an error here
+will show up in message log once, and the back-end will not be used for
+completion.
+
+`post-completion': Called after a completion candidate has been inserted
+into the buffer. The second argument is the candidate. Can be used to
+modify it, e.g. to expand a snippet.
The back-end should return nil for all commands it does not support or
does not know about. It should also be callable interactively and use
-`company-begin-backend' to start itself in that case."

+
+Grouped back-ends:
+
+An element of `company-backends' can also itself be a list of back-ends,
+then it's considered to be a \"grouped\" back-end.
+
+When possible, commands taking a candidate as an argument are dispatched to
+the back-end it came from. In other cases, the first non-nil value among
+all the back-ends is returned.
+
+The latter is the case for the `prefix' command. But if the group contains
+the keyword `:with', the back-ends after it are ignored for this command.
+
+The completions from back-ends in a group are merged (but only from those
+that return the same `prefix').
+
+Asynchronous back-ends:
+
+The return value of each command can also be a cons (:async . FETCHER)
+where FETCHER is a function of one argument, CALLBACK. When the data
+arrives, FETCHER must call CALLBACK and pass it the appropriate return
+value, as described above.

+True asynchronous operation is only supported for command `candidates', and
+only during idle completion. Other commands will block the user interface,
