Ignore trigger key prefixes that are shorter than symbol-at-point

[gnu-emacs-elpa] / NEWS.md

# History of user-visible changes

## Next

* `company-yasnippet` supports `yas-key-syntaxes` better. But we use them in the
  reverse order, preferring the longest key prefix that matches anything. And we
  only consider trigger key prefixes that are at least as long as the symbol at
  point, which effectively means skipping the `"w"` element
  ([#422](https://github.com/company-mode/company-mode/issues/422)).
* New user option `company-search-regexp-function`.
* Completion is not started automatically when a keyboard macro is being
  recorded ([#374](https://github.com/company-mode/company-mode/issues/374)).
* New command `company-indent-or-complete-common`.
* Backend command `doc-buffer` now can also return a cons of buffer and window
  start position.
* Backend command `ignore-case` has been documented.
* `company-template-c-like-templatify` does not replace the default argument
  values with `argN` anymore
  ([#336](https://github.com/company-mode/company-mode/issues/336)). This
  affects `company-clang` and all third-party backends that use this function.
* Likewise for `company-clang-objc-templatify`.
* `company-template-add-field` calling convention has changed.
* New user option `company-dabbrev-ignore-invisible`.
* `company-ropemacs` was removed. `ropemacs` supports completion via
  `completion-at-point-functions` starting with version 0.8.
* `company-pysmell` was removed.
* `company-select-next`, `company-select-previous`,
  `company-select-next-or-abort`, `company-select-previous-or-abort` and
  `company-complete-common-or-cycle` accept a numeric argument.
* The documentation buffer window can be scrolled with the mouse wheel.

* `company-backends`: `prefix` command can return `t` in the cdr.
* `company-clang-begin-after-member-access`: New option.
* Mouse click outside the tooltip aborts completion.

* `company-dabbrev-code` supports all `prog-mode` derivatives.

## 2013-04-01 (0.6.6)

* `company-elisp` doesn't offer completions when typing the name and the
  arguments of a new function or macro definition, allowing to fall back to
  other back-ends like `company-dabbrev-code`.

## 2013-03-30 (0.6.5)

* Fixed keybindings when running in a terminal.
* `company-elisp-show-locals-first`: new customizable variable.
* `company-elisp` shows more accurate and comprehensive candidates list.

## 2013-03-26 (0.6.4)

* `company-eclim` shows valid completions after an opening paren.
* Expanded template does not get removed until the point leaves it.  After your
  input the last argument in a method call expanded by `company-eclim`, you can
  press `<tab>` once more, to jump after the closing paren.  No other bundled
  back-ends are affected.

## 2013-03-25 (0.6.3)

* New tooltip face colors used on themes with light background.

  action (such as `company-complete-{selection,number,mouse}`).

  fields, it's displayed at the beginning, not right after it; `<tab>` jumps to
  the next field, `forward-word` and `subword-forward` remappings are removed;
  when you jump to the next field, if the current one hasn't been edited, the
  overlay gets removed but the text remains.
* `company-eclim` shows method overloads and expands templates for calls.
* `company-clang-objc-templatify` does not insert spaces after colons anymore.
* `company-clang` is now only initialized in supported buffers.
  So, no error messages if you don't have Clang until you open a C file.
* `company-clang` recognizes Clang included in recent Xcode.
* New commands `company-select-previous-or-abort` and
  `company-select-next-or-abort`, bound to `<up>` and `<down>`.

## 2013-03-19 (0.6)

* Across-the-board bugfixing.
* `company-pysmell` is not used by default anymore.
* Loading of `nxml`, `semantic`, `pymacs` and `ropemacs` is now deferred.
* Candidates from grouped back-ends are merged more conservatively: only
  back-ends that return the same prefix at point are used.
* `company-clang` now shows meta information, too.
* Some performance improvements.
* Fixed two old tooltip annoyances.
* 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 accidentally circumvent `paredit-mode`
  when it's enabled.
* `company-elisp` has seen some improvements.
* Added `company-capf`: completion adapter using
  `completion-at-point-functions`.  (Stefan Monnier)
