Provide identifier completion result by YCM

[LinSHP]

I installed the youcompleteme and complet configurations like setting "ycmd.path" and "ycmd.global_extra_config". But When I edit .c file..nothing happens. Is there any other configurations I need to set?

PS:English is poor..sorry

[richard1122]

Could you set ycmd.debug=true in settings and have a look at logs?

PS Chinese is also OK.

[LinSHP]

我设置了ycmd.debug=true，但是不知道去哪里找log file。搜了下发现是输入:YcmDebugInfo，但是在哪里输呢

[richard1122]

在 vscode 里面打开输出面板，选择 ycm 插件的输出，就可以直接在 vscode 里面查看

[richard1122]

可能需要继续写一下代码，试图做一下补全？

[LinSHP]

比如说我这个时候输maxLen，难道它不应该给我自动补全，或者一些提示什么的。但是什么也没发生？

[richard1122]

有些操作才能触发一些补全。比如说定义一个结构体，然后对 实例输入 . 调用成员变量的时候，你试试？

[LinSHP]

是的，和你说的一样，结构体实例是可以补全成员变量的。 那么变量就不能自动补全吗，或者你有什么推荐的可以自动补全变量名的插件？ 十分感谢

[richard1122]

这是目前 vscode 对补全插件的一些限制，需要用一些按键来触发补全，所以我就预先定义了包括 . -> 等等的几个。 我会看看是否有更好的方式来绕过这部分限制的。

[LinSHP]

好的，非常感谢你的帮助！

[richard1122]

我打算修改一下这个 issue 的标题让它更符合问题一些，如果你觉得不合适请直接指出~

[richard1122]

我确认了一下的确没法让 vscode 每次都调用补全的，如果需要的话你可以使用 ctrl + space 来让 vscode 强制进行补全。 https://github.com/Microsoft/vscode-tips-and-tricks#intellisense

[michaelHL]

@richard1122 插件 C/C++ Clang Command Adapter 的补全比较完整(除了那些trigger比如 ., ::, >，字母开头的结构名、函数名也能够提示)：

上面关于C/C++的插件仅 C/C++ Clang Command Adapter 一个. 但是vscode-ycm必须通过加上 . 才能「激活」这些功能：

上面的图片删除了前述插件并仅安装vscode-ycm，请问这是ycmd的问题呢还是插件的问题呢？提示补全可否更进一步呢？😃

测试环境各版本如下：

• OS: Windows 10 (1607 x64)
• VSCode: 1.14.2

其中的ycmd是利用如下工具在win下编译的(根据官方的安装指南)：

• LLVM 4.0.1x64
• Python 2.7.10 x64
• MinGW GCC 7.1.0 x86_64-posix-seh-rev1
• Cmake 3.9.0 x64
• Visual Studio 2017

VSCode中关于插件的配置如下：

"ycmd.path": "E:\\YouCompleteMe\\third_party\\ycmd",
"ycmd.confirm_extra_conf": true,
"ycmd.global_extra_config": "F:\\WorkingDirectory\\Configuration\\common\\_ycm_extra_conf.py",
"ycmd.python": "D:\\Python\\Python27\\python.exe",

配置中的文件为 _ycm_extra_conf.py

感谢作者的付出！

[michaelHL]

应该是ycmd的机制问题，它仅在特定的trigger之后触发

• is c library function auto-completed?
• Why doesn't YouCompleteMe complete function paramters?

哈哈我自言自语了！ 😄
