パッチを適用するパスを-patchApplyLocation、
パッチファイルを-patchPathに記述して引数として与えます。
-patchApplyLocation,-patchPathはペアになっており、複数回指定可能です。

# パッチ適用済みバイナリ(Windows Only)<a id="sec-5" name="sec-5"></a>
<https://github.com/yaruopooner/ac-clang/releases>
上記に置いてあるclang-server-X.X.X.zipは
パッチ適用済みのバイナリとライブラリファイル
- clang-server.exe
- libclang.dll
- libclang.lib or libclang.imp
の３ファイルが格納されています。
LLVMはセルフビルドせずにclang-serverのみをセルフビルドする場合は
clang-server-X.X.X.zipをac-clangに解凍します。
すると以下のように配置されます。
ac-clang/clang-server/binary/clang-server.exe
ac-clang/clang-server/library/x86\_64/release/libclang.dll
ac-clang/clang-server/library/x86\_64/release/libclang.lib
# パッチを適用せずLLVMオフィシャルのlibclangを使用する場合の制限事項<a id="sec-6" name="sec-6"></a>
## 特定ファイルがロックされセーブできなくなる<a id="sec-6-1" name="sec-6-1"></a>
編集したヘッダファイルをセーブしようとすると "basic-save-buffer-2: Opening output file: invalid argument \`HEADER-FILE-NAME\`" となりセーブできない。
必ず発生するわけではなく特定の条件を満たしたファイルサイズが16kBを越えるヘッダファイルで発生する。
16kB以下のヘッダファイルではまったく発生しない。
libclang の TranslationUnit(以下TU) の問題。
libclang の TU がinclude対象のファイルをロックしている。
ac-clang側で暫定対処パッチを施してあるので多少は緩和されているが完全に回避はできない。
発生した場合はマニュアル対処する以外ない。
### emacs側での対処方法<a id="sec-6-1-1" name="sec-6-1-1"></a>
include対象なので大抵は foo.cpp/foo.hpp という構成だとおもわれます。
foo.hpp(modified)がセーブできない場合、大抵foo.cppが(modified)になっているのでfoo.cppをセーブしましょう。
これによりfoo.hppはセーブ可能になるはずです。
これでもセーブできない場合は、foo.cpp以外のソースでfoo.hppをインクルードしており(modified)になっているバッファがあるはずなので
それもセーブしましょう。
また、定義へのジャンプ機能で該当ソースがアクティブ化されている場合は、未編集バッファであってもアクティブ化されています。
該当バッファを削除してみるか、そのバッファへスイッチして (ac-clang-deactivate) を実行してください。
これ以外でも16kBを越えるヘッダを編集しようとした際に、そのファイルのcppはオープンしてもいないのにセーブできない場合、
該当ヘッダファイルを何処か遠いモジュールでインクルードしている場合なども同様の症状になります。
ライブラリモジュールやフレームワークなどを開発している場合は発生しやすいかもしれません。
※ライブラリ・フレームワークはアプリ側からよくincludeされるため。
### 原因（実装上の問題説明、解決案求む）<a id="sec-6-1-2" name="sec-6-1-2"></a>
foo.cpp(modified)のとき foo.cppのセッションで
TUが foo.cpp パース後もincludeされているファイルのロックを保持しつづけている。
この状態で foo.hpp を編集してセーブしようとするとロックでエラーになる。
ロックを解除するには、 foo.cpp のTUをリリースする。
なので foo.cpp セーブ時にセッションは保持した状態で TU だけをリリースして、
foo.cpp が再び modified になったときに TU を生成するように修正。
これにより foo.cpp セーブ後であればincludeロックでが全解除されるので foo.hpp がセーブ可能になる。
当然 foo.cpp 以外に foo.hpp をinclude しているソースでかつ、編集中のバッファがある場合は、
それら全てを保存しないとロックでは解除されない。
Windows環境において、
このロックはI/Oのopen関数によるロックはではなくWindowsAPIのCreateFileMappingによるロックである。
libclang FileManagerは16kB以上のファイルをメモリマップドファイルとしてアロケーションする。
TUがリリースされるとUnmapViewOfFileによりメモリマップドファイルがリリースされるようになりファイルに対して書き込み可能になる。
Linux環境においても発現する不具合はWindows環境と若干異なるものの mmap/munmapによる問題は発生する。
foo.cppのTUを保持している状態でfoo.hppにおいてclass fooのメソッドを追加・削除し保存する。
foo.hpp更新後にfoo.cppにおいてclass fooのメソッドを補間しようとするとTUがクラッシュする。
libclangがSTDOUTに "libclang: crash detected in code completion" を出力する。
clang-serverのプロセスは生きており、セッションを破棄して再生成すれば補間続行は可能。
## その他<a id="sec-6-2" name="sec-6-2"></a>
上記の問題はlibclangにパッチを適用して改善している。
パッチを適用したリリースバイナリのlibclang-x86\_XX.(dll or so)を使用している場合は発生しない。
パッチを適用していないLLVMセルフビルドおよび、LLVMオフィシャルバイナリを使用する場合にのみ問題が発生します。
clang側の仕様バグなので現在LLVM bugzilla に報告済み。対応待ち中。
<http://llvm.org/bugs/show_bug.cgi?id=20880>
# パッチ解説<a id="sec-7" name="sec-7"></a>
## パッチ<a id="sec-7-1" name="sec-7-1"></a>
ac-clang/clang-server/patch/invalidate-mmap.patch
を使用。
cd llvm/
svn patch ac-clang/clang-server/patch/invalidate-mmap.patch
## パッチ(invalidate-mmap.patch)で行っている事<a id="sec-7-2" name="sec-7-2"></a>
mmapを使わないようにパッチを適用している
適用するのは以下のソース
clang-trunk/llvm/lib/Support/MemoryBuffer.cpp
static error_code getOpenFileImpl(int FD, const char *Filename,
OwningPtr<MemoryBuffer> &result,
uint64_t FileSize, uint64_t MapSize,
int64_t Offset, bool RequiresNullTerminator) {
↑の関数内で呼ばれる shouldUseMmap によりファイルに対するmmapの使用可否が判断される
static bool shouldUseMmap(int FD,
size_t FileSize,
size_t MapSize,
off_t Offset,
bool RequiresNullTerminator,
int PageSize) {
この関数のresultが常時falseであればmmapは恒久的に使用されない。
よってこの関数の先頭で
return false;
とすればよい。
以降のコードは#if 0 end するなりすればよい。
## LLVM3.5の追加仕様<a id="sec-7-3" name="sec-7-3"></a>
shouldUseMmap,getOpenFileImplに引数IsVolatileSizeが追加された。
これはshouldUseMmapまで加工なしでパスされ、
shouldUseMmap先頭において、
if (IsVolatileSize)
return false;
される。
コメントがついていた
// mmap may leave the buffer without null terminator if the file size changed
// by the time the last page is mapped in, so avoid it if the file size is
// likely to change.
mmapはファイルサイズが最後のページがマップされたされた時点で変更された場合はnull終端せずにバッファを残すので、ファイルサイズが変更される可能性がある場合は、それを回避することができる。
とは言っているものの、想定されていない事態がいろいろあるようで仕様抜けの模様。
またバッファ確保系関数の上流で IsVolatileSize が指定されていなかったりコンストラクタのデフォルト値のまま運用されている箇所が何箇所か見受けられた。
そういった箇所を自前で修正してみたところ従来よりマシになったものの、他にも問題があるようで想定通りにmmapを制御は出来なかった。
LLVMのファイルシステム・メモリ周りの仕様を完全に把握していないと、ここら辺の修正は厳しいのかもしれない。
よって現時点においては上記パッチ適用が一番無難なやり方となる。

そういった箇所を自前で修正してみたところ従来よりマシになったものの、他にも問題があるようで想定通りにmmapを制御は出来なかった。
LLVMのファイルシステム・メモリ周りの仕様を完全に把握していないと、ここら辺の修正は厳しいのかもしれない。
よって現時点においては上記パッチ適用が一番無難なやり方となる。

# About this document<a id="sec-1" name="sec-1"></a>
This is explained about self-build of clang-server.
When you use clang-server binary for distribution on Windows environment, it is not necessary to read this document.
# Step of self-build<a id="sec-2" name="sec-2"></a>
A build of clang-server requires libclang of LLVM.
Therefore, first self-build is LLVM libclang, next self-build is clang-server.
## LLVM self-build<a id="sec-2-1" name="sec-2-1"></a>
You have to do four step of following.
There is also a script which simplify this work.
- Checkout LLVM
- Apply patch to LLVM for libclang
- Project file generation by CMAKE or configure
- Build
## clang-server self-build<a id="sec-2-2" name="sec-2-2"></a>
Patch applied libclang library use by LLVM self-build
Use the patch applied libclang library
- Project file generation by CMAKE
- Build
- Installation
# Software required for self-build<a id="sec-3" name="sec-3"></a>
## Windows<a id="sec-3-1" name="sec-3-1"></a>
The following is required.
### LLVM<a id="sec-3-1-1" name="sec-3-1-1"></a>
The following built library is required.
libclang.lib or libclang.imp
libclang.dll
### Visual Studio 2015/2013/2012/2010<a id="sec-3-1-2" name="sec-3-1-2"></a>
any OK
### CMake<a id="sec-3-1-3" name="sec-3-1-3"></a>
<http://www.cmake.org/>
Download cmake archive, and decompress to any location.
CMake is used for Visual Studio Solution File generation and build and installation.
## Linux<a id="sec-3-2" name="sec-3-2"></a>
The following is required.
### LLVM<a id="sec-3-2-1" name="sec-3-2-1"></a>
The following built library is required.
libclang.so
### CMake<a id="sec-3-2-2" name="sec-3-2-2"></a>
$ sudo apt-get install cmake
If you want to use latest version, download from following
<http://www.cmake.org/>
e.g.
Download cmake-3.1.3.tar.gz, and decompress to work directory.
You perform a build and installation.
$ tar -xf cmake-3.1.3.tar.gz .
$ cd cmake-3.1.3
$ ./configure && make
$ make install
# Self-Build<a id="sec-4" name="sec-4"></a>
## Windows<a id="sec-4-1" name="sec-4-1"></a>
### LLVM<a id="sec-4-1-1" name="sec-4-1-1"></a>
Required process for LLVM self-build.
And you must apply patch to LLVM before build.
It isn't necessary install a package after self-build.
You must designate generated binary PATH after LLVM self-build at CMake project generation argument.
Therefore clang-server is able to build.
When LLVM is already installed, you must designate installed directory of LLVM.
When you want to self-build,
Checkout from SVN by yourself, and perform the LLVM Solution File generation and build by cmake.
Or, use following script.
<https://github.com/yaruopooner/llvm-build-shells>
1. How to designate the LLVM patch in the script
You will designate -tasks to the argument of builderShell,
and designate PATCH to the parameter of -tasks,
It will gives a table that describes the path to apply the patch and patch file to parameter of -patchInfos.
Please refer to the sample.ps1 of llvm-build-shells for details.
2. The contents of the LLVM patch
Use of mmap always invalidation.
### clang-server<a id="sec-4-1-2" name="sec-4-1-2"></a>
Use the ac-clang/build/builder\_sample.bat
Please edit the builder\_sample.bat as necessary.
It's necessary to execute in the command line or Windows Explorer.
- example
cmake -G "Visual Studio 12 2013 Win64" ../clang-server -DLIBRARY_PATHS="c:/cygwin-x86_64/tmp/llvm-build-shells/ps1/clang-360/build/msvc-64/" -DCMAKE_INSTALL_PREFIX="c:/cygwin-x86_64/usr/local/bin/"
- Option commentary
- `-DLIBRARY_PATHS`
You have to designate location of LLVM self-build completed directory.
It is necessary to designate the directory that a binary was generated.(e.g. {LLVM output path}/Release/)
If you omit this option, value will be use `ac-clang/clang-server` .
- `-DCMAKE_INSTALL_PREFIX`
You have to designate installation location of clang-server.
If you omit this option, value will be use `C:/Program Files/clang-server` .
## Linux<a id="sec-4-2" name="sec-4-2"></a>
### LLVM<a id="sec-4-2-1" name="sec-4-2-1"></a>
Required process for LLVM self-build.
And you must apply patch to LLVM before build.
It isn't necessary install a package after self-build.
You must designate generated binary PATH after LLVM self-build at CMake project generation argument.
Therefore clang-server is able to build.
When LLVM is already installed, you must designate installed directory of LLVM.
When you want to self-build,
Checkout from SVN by yourself, and perform the LLVM Solution File generation and build by cmake.
Or, use following script.
<https://github.com/yaruopooner/llvm-build-shells>
1. How to designate the LLVM patch in the script
You will designate -patch to the argument of executeBuilder.
Add to -patchApplyLocation the path where you want to apply the patch.
You write the patch file to -patchPath gives as an parameter.
-patchApplyLocation,-patchPath becomes the pair, it is possible to multiple times designate.
Please refer to the sample.sh of llvm-build-shells for details.
2. The contents of the LLVM patch
Use of mmap always invalidation.
### clang-server<a id="sec-4-2-2" name="sec-4-2-2"></a>
Use the ac-clang/build/builder\_sample.sh
Please edit the builder\_sample.sh as necessary.
Execute the builder\_sample.sh
- example
cmake -G "Unix Makefiles" ../clang-server -DLIBRARY_PATHS="/home/yaruopooner/work/llvm-build-shells/sh/clang-350/build" -DCMAKE_INSTALL_PREFIX="~/work/clang-server"
- Option commentary
- `-DLIBRARY_PATHS`
You have to designate location of LLVM self-build completed directory.
It is necessary to designate the directory that a binary was generated.(e.g. {LLVM output path}/Release/)
If you omit this option, value will be use `ac-clang/clang-server` .
- `-DCMAKE_INSTALL_PREFIX`
You have to designate installation location of clang-server.
If you omit this option, value will be use `/usr/local/bin` .
# Patch was applied binary(Windows Only)<a id="sec-5" name="sec-5"></a>
<https://github.com/yaruopooner/ac-clang/releases>
clang-server-X.X.X.zip is you can download from the above
The archive is 3 files contain, these file applied patch.
- clang-server.exe
- libclang.dll
- libclang.lib or libclang.imp
When you want to self-build only clang-server without LLVM,
clang-server-X.X.X.zip decompress to ac-clang directory.
Then, it will be placed in the following.
ac-clang/clang-server/binary/clang-server.exe
ac-clang/clang-server/library/x86\_64/release/libclang.dll
ac-clang/clang-server/library/x86\_64/release/libclang.lib
# Restrictions when you use LLVM official libclang without applying a patch<a id="sec-6" name="sec-6"></a>
## A specific file is locked and cannot save it<a id="sec-6-1" name="sec-6-1"></a>
When you try to save the edited header file,
it will be "basic-save-buffer-2: Opening output file: invalid argument \`HEADER-FILE-NAME\`",
and you can't save.
This occur if it meets certain conditions.
This condition is met when the header file size is larger than 16kB.
It is not at all occur when header file size is smaller than 16kB.
This issue belong to TranslationUnit(TU) of libclang.
The inclusion target file is locked by TU of libclang.
By performing a provisional transaction in ac-clang side, the more or less is erased, but it can't be avoided perfectly.
When this issue is occurring, only manual handle can be avoided.
### Solution in Emacs side<a id="sec-6-1-1" name="sec-6-1-1"></a>
I suppose that combination of source file is foo.cpp/foo.hpp.
When foo.hpp(modified) can't save, foo.cpp is (modified) often, so foo.cpp have to saved.
Therefore, foo.hpp should be possible to save.
When this can't save,
foo.hpp is included by source files besides foo.cpp, and it has (modified) status.
You have to save those.
And, when corresponding source is activated by definition jump feature, even if buffer don't modified that buffer is activated.
You try remove corresponding buffer, or (ac-clang-deactivate) must be execute in buffer.
In other cases, when you try save header file that file size larger than 16kB
When you save a header file of larger than 16kB, if it fails.
And that header file does not opened.
In this case, header file is included by a far module from current source file.
When you having developed a library module framework, it may be easy to occur.
because library and framework is included from application side.
### Issue(Implementation issues explanation, it wanted suggested solutions)<a id="sec-6-1-2" name="sec-6-1-2"></a>
When session of "foo.cpp" is edited in the buffer,
TU continue locking to included header file after parsed "foo.cpp".
When you edit and save to "foo.hpp" in this state, it occur error, because file is locked by mmap.
Therefore I modified a server as follows.
So while maintaining the session when "foo.cpp" saving,
TU is generated when "foo.cpp" is edited after TU released.
Therefore "foo.hpp" is possible to save that the included header file is unlocked after "foo.cpp" saved.
When a "foo.hpp" is included buffer where exist in buffer editing group without buffer of "foo.cpp",
the lock is not released when you does not save all them.
In the Windows environment,
This lock is not open function of I/O, is a lock by CreateFileMapping of WindowsAPI.
libclang FileManager does allocation to memory mapped file for the files larger than 16kB.
When TU is released, memory mapped file is released by UnmapViewOfFile, these becomes writable to file.
In the Linux environment,
problems with mmap/munmap bug differ slightly from the Windows environment, but also occurred in Linux environment.
The method add to "class Foo" in "foo.hpp" in the state that holds TU of "foo.cpp", and save to file.
After "foo.hpp" update, when you try complete method of "class Foo" in the "foo.cpp", TU will crash.
in this case, libclang output to STDOUT that "libclang: crash detected in code completion"
libclang output "libclang: crash detected in code completion" to STDOUT.
The process of clang-server is living in this situation.
Completion is possible after deletion of session and creation of session.
## Miscellaneous<a id="sec-6-2" name="sec-6-2"></a>
The above problems are solved by patching for libclang.
When you use the patch applied release binary(libclang.dll or so) it is not occur.
When you use the patch does not applied to LLVM self-build and LLVM official binary, this problem is occur.
I think specification bug of clang side. This problem has been reported to LLVM bugzilla. in the corresponding waitting.
<http://llvm.org/bugs/show_bug.cgi?id=20880>
# Patch commentary<a id="sec-7" name="sec-7"></a>
## Patch<a id="sec-7-1" name="sec-7-1"></a>
Use the ac-clang/clang-server/patch/invalidate-mmap.patch
cd llvm/
svn patch ac-clang/clang-server/patch/invalidate-mmap.patch
## The contents of the LLVM patch(invalidate-mmap.patch)<a id="sec-7-2" name="sec-7-2"></a>
Patch is applied so as not to use mmap.
Apply to the following source code to
`clang-trunk/llvm/lib/Support/MemoryBuffer.cpp`
static error_code getOpenFileImpl(int FD, const char *Filename,
OwningPtr<MemoryBuffer> &result,
uint64_t FileSize, uint64_t MapSize,
int64_t Offset, bool RequiresNullTerminator) {
It is determined availability of mmap for file by shouldUseMmap call from the above function.
static bool shouldUseMmap(int FD,
size_t FileSize,
size_t MapSize,
off_t Offset,
bool RequiresNullTerminator,
int PageSize) {
When the result of function is always false, mmap is not never used.
Therefore, the following modify has been applied to the top of this function.
#if 1
return false;
#else
/* original codes */
#endif
## TODO Additional Specification of LLVM3.5<a id="sec-7-3" name="sec-7-3"></a>
IsVolatileSize has been added to arguments of shouldUseMmap and getOpenFileImpl.
This will be passed unchanged to shouldUseMmap.
It is executed as follows in the shouldUseMmap top.
if (IsVolatileSize)
return false;
Following comments had been attached
// mmap may leave the buffer without null terminator if the file size changed
// by the time the last page is mapped in, so avoid it if the file size is
// likely to change.
Although that said, there is a situation which isn't assumed Variously, I'm supposing that mistake of specification.
Moreover, upstream function of buffer association function
I was found some place where is not designated value of IsVolatileSize and is used default value of constructor argument.
I tried modified it.
Result was become more better than conventional.
But it seem to have a problem, because I was not able to control mmap like a assumption.
I'm not enough understand the specification of around the file system and memory of LLVM.
For that reason that the rightly correction is difficult.
Therefore, the above patching becomes the most safe way at present.

OwningPtr<MemoryBuffer> &result,
uint64_t FileSize, uint64_t MapSize,
int64_t Offset, bool RequiresNullTerminator) {
#+end_src
It is determined availability of mmap for file by shouldUseMmap call from the above function.
#+begin_src C++
static bool shouldUseMmap(int FD,
size_t FileSize,
size_t MapSize,
off_t Offset,
bool RequiresNullTerminator,
int PageSize) {
#+end_src
When the result of function is always false, mmap is not never used.
Therefore, the following modify has been applied to the top of this function.
#+begin_src C++
#if 1
return false;
#else
/* original codes */
#endif
#+end_src
** TODO Additional Specification of LLVM3.5
IsVolatileSize has been added to arguments of shouldUseMmap and getOpenFileImpl.
This will be passed unchanged to shouldUseMmap.
It is executed as follows in the shouldUseMmap top.
#+begin_src C++
if (IsVolatileSize)
return false;
#+end_src
Following comments had been attached
#+begin_src C++
// mmap may leave the buffer without null terminator if the file size changed
// by the time the last page is mapped in, so avoid it if the file size is
// likely to change.
#+end_src
Although that said, there is a situation which isn't assumed Variously, I'm supposing that mistake of specification.
Moreover, upstream function of buffer association function
I was found some place where is not designated value of IsVolatileSize and is used default value of constructor argument.
I tried modified it.
Result was become more better than conventional.
But it seem to have a problem, because I was not able to control mmap like a assumption.
I'm not enough understand the specification of around the file system and memory of LLVM.
For that reason that the rightly correction is difficult.
Therefore, the above patching becomes the most safe way at present.

company: Release 0.6.6
## 2013-04-01 (0.6.6)

closing paren. No other bundled back-ends are affected.

* New tooltip face colors used on themes with light background.
* Pseudo-tooltip stays up-to-date when text is inserted after the
point.

* Futher improvement in `org-indent-mode` compatibility.
## 2013-08-18 (0.6.11)
* `company-template-c-like-templatify` removes all text after closing paren, for
use in backends that display additional info there.
* `company-cmake` is now bundled.
* Better `linum` compatibility in Emacs <= 24.2.
* `company-global-modes`: New option.
## 2013-05-26 (0.6.10)
* Plays nicer with `org-indent-mode`.
* Works in horizontally scrolled windows.
## 2013-05-10 (0.6.9)
* `company-capf` respects `:exit-function` completion property.
* `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-clang` uses standard input to pass the contents of current buffer to
Clang 2.9+, otherwise saves the buffer and passes the path to the file.
* `company-clang-auto-save` option has been removed.
* Better interaction with `outline-minor-mode`.
* `company-dabbrev-code` supports all `prog-mode` derivatives.
## 2013-04-16 (0.6.8)
* `company-auto-complete` is disabled by default.
* `company-auto-complete-chars` default value includes fewer syntax classes.
* In expanded function calls, arguments skipped by the user default to "argN".
* `company-eclim` and `company-clang` do not strip argument types from fields.
* `company-clang` expands function calls for all three modes now.
* `company-clang` supports `c++-mode` by default.
## 2013-04-05 (0.6.7)
* Two `company-elisp` tweaks.
## 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.
* Pseudo-tooltip stays up-to-date when text is inserted after the point.
* Fixed `company-require-match` mechanics.
## 2013-03-24 (0.6.2)
* `global-company-mode` is now autoloaded.
## 2013-03-23 (0.6.1)
* Documented `init` and `post-completion` back-end commands.
* `company-eclim` and `company-clang` only expand the template on explicit user
action (such as `company-complete-{selection,number,mouse}`).
* `company-template` has some breaking changes. When point is at one of the
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)
* Clang completions now include macros and are case-sensitive.
* Switching between tag files now works correctly with `company-etags`.
## 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)
* Initial release.

(autoload 'company-mode "company" "\
\"complete anything\"; is an in-buffer completion framework.
Completion starts automatically, depending on the values
`company-idle-delay' and `company-minimum-prefix-length'.
Completion can be controlled with the commands:
`company-complete-common', `company-complete-selection', `company-complete',
`company-select-next', `company-select-previous'. If these commands are
called before `company-idle-delay', completion will also start.
Completions can be searched with `company-search-candidates' or
`company-filter-candidates'. These can be used while completion is
inactive, as well.
The completion data is retrieved using `company-backends' and displayed
using `company-frontends'. If you want to start a specific back-end, call
it interactively or use `company-begin-backend'.

;;
;; Using `emacs-eclim' together with (or instead of) this back-end is

;; The alternative back-end provided by `emacs-eclim' uses `yasnippet'
;; instead of `company-template' to expand function calls, and it supports
;; some languages other than Java.
