youcompleteme's Issues

doesn't recognise vim 7.3.669 and I have 'YouCompleteMe unavailable: requires Vim 7.3.584+' error

If I put down patch which I have:

It works fine. Is it necessary to have exact version !has( 'patch584' ) check?

Consider using jedi instead of rope for python completion

jedi is an autocompletion library for Python that has it's own vim plugin (jedi-vim). I use it and find it to be quite good and more reliable than rope-based Python completion plugins.

FWIW, I might have time to try and get this going myself, if it's not too early to start using/extending the API's used by the existing semantic completer.

"YouCompleteMe unavailable: requires python 2.x" message despite Python 2.x being installed

Probably user stupidity, but it doesn't seem to work?

I've installed MacVim, symlinked mvim properly so I get to use the correct vi version in terminal. I've installed Vundle, and added the default required things, plus YouCompleteMe into ~/.vimrc

set nocompatible               " be iMproved
filetype off                   " required!
set rtp+=~/.vim/bundle/vundle/
call vundle#rc()
" let Vundle manage Vundle
" required! 
Bundle 'gmarik/vundle'
Bundle 'https://github.com/Valloric/YouCompleteMe.git'
set completeopt+=preview

I've done the :BundleInstall, and it installed correctly. Built ymc, and was told it was installed successfully. But when I start using vim to type, I get these at the status area:

-- ^X mode (^]^D^E^F^I^K^L^N^O^Ps^U^V^Y)
-- User defined completion (^U^N^P) Pattern not found

No auto complete box or anything coming up.

For reference, vim --version shows: VIM - Vi IMproved 7.3 (2010 Aug 15, compiled Dec 12 2012 16:22:25)

Reconsider all bindings

The assumption that i_<Tab>, i_<S-Tab>, <Leader>d, etc., are all available to a new plugin is going to slow adoption. Many other tools already make use of these.

I think we should figure out if there is a less-prominent set of bindings to use by default, and relegate the existing ones to the README.

calling YCmDiags when no complete file present run's indefenently

calling YCmDiags when not extra_conf file is present or set globally will block vim forever...

YCM should query Vim's omnicomplete system if available

Currently, YCM seems to only support keyword completion for languages outside the C Family (tested with PHP, JS, CSS and Python). While this completion mechanism may have its merits it is quite dumb. Omni completion generally provides much more useful suggestions. You can compare these two screenshots to get an idea…

YCM:

Omni completion:

Additionally, the message in the command-line says "User defined completion" but :set completefunc=javascriptcomplete#CompleteJS (tested to work with <C-x><C-u>) doesn't seem to have any effect whatsoever: only keyword completion is used.

Thanks for your attention.

YouCompleteMe config not used for initial syntastic pass.

Each time I open a file, I get a compilation errors that disappear after a short while.

It seems that the error are there because syntastic is making an initial checking without using the config options that I have in .ycm_extra_conf.py and which are required to compile the source.

I guess that could be somehow improved. Ideally the let g:syntastic_check_on_open=1 should take into account the things that are in .ycm_extra_conf.py.

Error loading ycm_core in python

Using the current version, I get this error when running vim:

Error importing ycm_core. Are you sure you have placed a version 3.2+ libclang.[... the docs. Full error: dynamic module does not define init function (initycm_core)

I looked into where this is coming from, and it's just python trying to import the ycm_core module. I've tried to manually import this from the python shell, and I get the same error:

ImportError: dynamic module does not define init function (initycm_core)

First of all, this isn't the bug that YCM reports (which has something to do with clang). But I can't figure out what is causing this error.

I compiled a test boost_python library, and found that it exports the functions _init and init_module_MODULENAME, and there is an init_module_ycm_core function exported from ycm_core.so. Not sure if that's helpful, but it is something I found.

Any help with this? I'm more than welcome to provide any information that you need.

For reference, I'm running:
Arch Linux 3.7.5
I have both python2 and python3 installed, vim has +python and -python3
I'm using my system clang, which I built from svn, but I've tried it with the ubuntu release clang, and it fails then too

Compile error on OSX 10.7

On Lion I get a compile error:

System info:

Is Lion unsupported?

Error with syntastic integration

Syntastic works fine with .py and .js file, but fails with .c file. When I input :w command to check the c file, it fails with such errors:

处理 function 37_UpdateErrors..37_CacheErrors..5 时发生错误：

No completion available for Go Lang

It doesn't complete anything for a file with ft:go. If I changed it than the completion doesn't complete any words that are already written in the file.

CMake fails on second run if directory is not emptied

Lets say I run cmake for a first time with cmake -G "Unix Makefiles" -DPATH_TO_LLVM_ROOT=/usr/lib/llvm . ~/local/share/vim/bundle/YouCompleteMe/cpp/ and it generates everything fine. Then I realize there's another flag for that and I run cmake -G "Unix Makefiles" -DEXTERNAL_LIBCLANG_PATH=/usr/lib/llvm/libclang.so . ~/local/share/vim/bundle/YouCompleteMe/cpp/. It fails with following message

Your C++ compiler supports C++11, compiling in that mode.
Using libclang to provide semantic completion for C/C++/ObjC
Using external libclang: TEMP-NOTFOUND
CMake Error: The following variables are used in this project, but they are set to NOTFOUND.

After a rm -rf ./* ($PWD is build directory) and cmake -G "Unix Makefiles" -DEXTERNAL_LIBCLANG_PATH=/usr/lib/llvm/libclang.so . ~/local/share/vim/bundle/YouCompleteMe/cpp/ works fine.

ycm_core.so built against wrong python lib when using homebrewed pythons and custom macvim builds

Problem

I use a homebrewed python2.7, and a custom homebrewed MacVIM (to include the split-browser frature).

With this setup, ycm_core.so is linked wrongly, causing a SIGABRT on vim startup:

$ otool -L ycm_core.so
ycm_core.so:

thank you very much !!

Feature: Code Navigation

Great work on the plugin btw, works as advertised.

Once you have the semantic completion using libclang configured, you are getting almost for free the ability to do code navigation (Find declaration, references, call hierarchy and more).

Any chance this is on the plans or is there a way to extend your plugin to achieve this?

ycm and autoindent: whitespace sometimes not removed

Vim with autoindent on adds whitespace when starting a new line. When pressing <esc> without typing anything, the whitespace is removed again. When ycm is activated, sometimes this whitespace is not removed. Sometimes it is.

How to reproduce:

Edit some file, e.g. vim foo.hs
Have autoindent on, smartindent and cindent off. I'm not sure if other settings are relevant, the output of :set is added below.
Type the following: i<space>``<space>hello<esc>o<esc>

Result: The first line consists of two spaces, followed by the word "hello". The second line consists of two spaces.
Expected: The second line is empty.

Can't build YouCompleteMe with Clang

So I had Clang as my default compiler on my system. When I tried to build YouCompleteMe with Clang, it kept failing with it saying it couldn't find a header (<cstddef> to be exact). My result looked something like this (click to expand):

I think it's something to do with Clang not using the includes provided by libstdc++6-4.7-dev (the one I use), only GCC seems able to finding this.

The following is my system specifications, just in case someone else runs into this issue.

Homebrew Vim

FWIW, if people insist on using Homebrew Vim, installing macvim via Homebrew will give them a console Vim that works with this plugin.

Completion is "noisy".

YouCompleteMe seems to frequently print some stuff on commandline. This is distracting.

Conflict with restore_view plugin

I have discovered that the following plugin breaks YouCompleteMe:

https://github.com/vim-scripts/restore_view.vim

When it is installed (using Vundle), YCM autocomplete will work correctly on the first file that is loaded, and any subsequent file loaded will fail to work.

I don't care for the restore_view plugin particularly, or know which is at fault, but as I spent a half hour tracking it down I felt obliged to open an issue for it here.

Thanks for the great work on the plugin!

SnipMate/UltiSnips integration

A killer feature would be for YCM to include SnipMate snippets in its suggestions.

I'm making this an issue in case a contributor sees this. I unfortunately do not have the skills required to build this.

Sometimes breaks auto-removal of whitespace-only lines

First of all, I love YCM, thanks for making it! It is much more performant than any other autocomplete plugin I've used.

I think this is possibly but not definitely related to Issue #24.

Steps to reproduce:

Type in some code that will trigger auto-indenting as well as the autocomplete box, e.g. in Ruby

def thing
end

Position cursor such that a new line will auto-indent e.g. anywhere on line with def thing
Use o to go to insert mode on an indented new blank line
Press esc to go to normal mode

Result:
Cursor at indented location.

Expected result:
Cursor at the beginning of the line, whitespace removed.

Expected result occurs if I disable YCM. Given that the autocomplete box pops up almost anytime you type, this bug has the effect of almost completely disabling the default vim behavior of removing whitespace on blank, undedited lines.

<leader>d doesn't show detailed error

Thanks for the awesome plugin.

I'm experiencing two issues when editing a c file with syntastic installed.

When the cursor is on a line with an error, the error only flashes for under a second
Pressing d results in this error:

Error detected while processing function 36_ShowDetailedDiagnostic:
line 1:
Traceback (most recent call last):
File "", line 1, in
File "/Users/c/Dropbox/linux/dotfiles/vim/vim.symlink/bundle/YouCompleteMe/autoload/../p

ython/completers/cpp/clang_completer.py", line 166, in ShowDetailedDiagnostic
diagnostics = self.diagnostic_store[ current_file ][ current_line ]
AttributeError: 'ClangCompleter' object has no attribute 'diagnostic_store'

I was able to fix the detailed report error by initializing self.diagnostic_store to None and checking if it's been properly initialized before usage.

Option to turn off complete as you type

Lovely plugin!

As requested in internal email, here is a bug report.

I hate to have the completion box open constantly - mainly because it hijacks my tab key which I cannot use for anything else anymore now. Would it be possible to start the YCM "mode" only when an initial tab is pressed?

Compiling on windows

Hi,

So, I have successfully compiled this on windows, and it works.

Here are some notes from my experience compiling it

Add these defined to the project definitions
BOOST_PYTHON_SOURCE
BOOST_ALL_NO_LIB
Add this somewhere to the ycm_core source (if you got tss_cleanup_implemented linking error)
namespace boost {
void tss_cleanup_implemented() {}
};
Python native libraries in windows uses .pyd not .dll extension, so change the extension in plugin/youcompleteme.vim @ line 38

Repeated 'No .ycm_extra_conf.py file detected' message

Using vim with ycm in a directory with no .ycm_extra_conf.py file, results in this message being seen repeatedly in the status line:
"
No .ycm_extra_conf.py file detected, so no compile flags are available. Thus no semantic support for C/C++/ObjC/ObjC++.
"
It seems to happen every time the display refreshes.

It should only display once, to stop the spam. It's legitimate to have your vim configured with ycm, but not all of your sandboxes.

"libclang.dylib" disappeared after compilation

Run into source loading error after completing all steps required and when opened vim.

Figured out it's because libclang.dylib was missing in the .vim/bundle/YouCompleteMe/python directory. Double-checked my cmd history and pretty sure I did copy the dylib into python before the compilation.

Fixed by copying it again. But you should either take a look at the issue or add a watch-out at the end of installation instruction.

I am running on x86_64 gentoo linux with gcc 4.4.7. I tried the system installed clang 3.2 and the binaries on http://llvm.org/releases/download.html#3.2 without success.

Even passing the full path to libclang.so via -DEXTERNAL_LIBCLANG_PATH did not work either.

Any ideas?

Cheers,
Gregor

Extra whitespace added when changing a line

I noticed a lot of white-space in my diffs after using this plugin. It is adding space characters to match the formatting even if there is a blank line. To reproduce:

Set your filetype to something, such as c so that it indents blocks.
Enter the following text:
```
if (foo) {
  bar;

  baz;
}
```
Move the cursor to the first character of the empty line. Note that it is an empty character.
Type cc to change the line.
Press esc to exit insert mode.

Expected: The line stays empty.
Actual: The line turns into two spaces.

Read .syntastic_c_config in .ycm_extra_conf.py

If you use syntastic with C, you already have your CPP flags stored in a file like .syntastic_c_config. YCM should read that if it's there, to save me pasting them or some other hack.

Something like this works for me: https://gist.github.com/tsto/4718358

Note, my python is terrible.

No .ycm_extra_conf.py file detected, so no compile flags are available. thus no semantic support

Hello this happened when I started it up for the first time. I have found the file ~/.vim/bundle/YouCompleteMe/cpp/ycm/.ycm_extra_conf.py so I wonder if it should reside somewhere else?

Ok, that error was due to having an assignment to d in my .vimrc.

It seems to work like a charm now, once I get used to it, and have read your docs. This is something I have craved.

Thanks a whole lot!

Wrong JSON compilation database file name in .ycm_extra_conf.py

# Set this to the absolute path to the folder (NOT the file!) containing the
# compilation_database.json file

The file has to be named as compile_commands.json in order to work properly.

Return to vim normal mode immediately after pressing ESC key

Currently, Vim returns to edit mode after pressing ESC key when the YCM's auto-complete popup is displaying. I'm used to SuperTab's behavior, so I find it a litte inconvenient to have to press ESC key 2 times to return to normal mode. Is there an option in YCM that help me change this behavior?

Create a homebrew packge for installation/compilation of shared lib on OSX.

Currently, one has to manually build the ycm_core.
Would be much better if this could be moved to a homebrew package
(pass args to the vim plugin folder during installation)

Getting "Vim: Caught deadly signal ABRT" after install.

I'm on OSX 10.8.2.

Steps I followed:

cd ~/.vim/bundle
git clone https://github.com/Valloric/YouCompleteMe.git
mkdir ~/dev/ycm_build
cd ~/dev/ycm_build
cmake -G "Unix Makefiles" . ~/.vim/bundle/YouCompleteMe/cpp

Got this output.

Now when I start vim, I get this:

➜  ycm_build  vim
Vim: Caught deadly signal ABRT
Vim: Finished.
[1]    10720 abort      vim

 ➜  ycm_build  vim
Vim: Caught deadly signal ABRT
Vim: Finished.
[1]    10740 abort      vim

Can't run MacVim after installing YCM

I installed YCM as per the instructions on the readme, and now MacVim crashes immediately after starting.

Running it in the terminal I get—

Fatal Python error: PyThreadState_Get: no current thread
Vim: Caught deadly signal ABRT
Vim: Finished.

I'm running MacVim 7.3 (snapshot 66) for OS X 10.8 (Mountain Lion), as downloaded from the official Google Code project page.

Running plain old Vim (which IIRC I brew installed), I get—

Vim: Caught deadly signal ABRT
Vim: Finished.
Abort trap: 6

When I ran :BundleInstall Valloric/YouCompleteMe, MacVim didn't crash—but then I'm not sure if it required an reboot to fully "install".

YouCompleteMe breaks ^u

With YouCompleteMe enabled, Ctrl+u no longer removes text from cursor to the beginning of line, as it does in regular vim. Instead it cycles through completion possibilities, like Ctrl+n does.

Intergrate with SnipMate?

Can YCM integrate with SnipMate (https://github.com/garbas/vim-snipmate) ?

Cause the trigger key for SnipMate is also Tab... How can I configure it?

Or is there another plugin like SnipMate but can easily integrate with YCM?

Characters get deleted as you type in vim files after saving

Hi, I noticed a strange behavior while editing vim files with MacVim and with Vim that comes shipped with MacVim itself. After saving a vim file, whatever word I type gets deleted after the first character so writing becomes practically impossible.

I'm running MacVim 7.3 (snapshot 66) on Mac OS X Mountain Lion 10.8

Make sure you link against python2

On Archlinux the default python is 3.x and you need to use python2 to get 2.x. Also need to include from /usr/lib/python2.7 not /usr/lib/python3.3m. Interestingly the ycm_core module compiles and loads fine as Py3 but ycm.py won't as it uses Py2 syntax. The error message in vim for this case incorrectly suggests that a missing libclang.so is to blame.

Complete CTRL+X CTRL+O ?

When I press CTRL+X CTRL+O in insert mode, there will pops a list of method I can use.

Can this be implemented in YCM? (i.e. don't need to press CTRL+X CTRL+O)

Consider adding the 'quick match' feature?

The 'quick match' of neocomplcache seems usefull. I think it would be fine to add this feature.
