deoplete-clang2's Issues

Exception during clang2.on_event for event 'Init': expected string or bytes-like object.

Hello,
I've just installed deoplete_clang2 and I'm getting this error when trying to edit a .c file:

Option to disable steal keys and completedone autocmd

I just want to use deoplete source.
But it has original arguments completion feature using autocmd.
I want to disable the feature.

Add example in readme.md with compile_commands.json

Hi, giving a try to deoplete from YCM.
Can we have an example on how to work with the compile_commands.json. It says no config required... but where should the json be? It is generated by cmake in the build folder, #14 but it should be in the root of the project right? That should be noticed to the user.

Also, for a deoplete noob, do I need something else to say to deoplete? Something like this maybe?
let g:deoplete#sources.cpp = ['buffer', 'clang2']

Thanks!

specify compile_commands.json location?

Hello,
Is there a setting to specify a directory (different than the root) that the plugin can use
for the location of the compilation database??

deolete deprecated "debug_enabled"

A recent commit from Shougo deprecates debug_enabled: Shougo/deoplete.nvim@ba4d03e

Not getting clang completion immediately

Hi,

I am using this plugin for C/C++ programming and I think it is great, especially for the parameters placeholders that avoid the sometimes annoying switches between tabs to have a look at man.

However, I noticed that the translation is not immediate/automatic: let's say I want to type mmap (includes are there already). What happens is that I don't get the clang completion immediately but I have to type a space in the middle of the word then go back and continue typing. Only now the clang completion appears. This is quite annoying since I would like to get the completion in realtime.

Anyone having the same issue?

Currently using nvim 0.2.0, clang 4.0 (tested also with 3.4.2 and seen the same behavior) and latest deoplete and deoplete-clang2 sources.

My init.vim

let g:deoplete#enable_at_startup = 1
let g:deoplete#sources#clang#sort_algo = 'priority'
set completeopt-=preview

Thanks,

Christian

Fresh install throws an error?

Not sure if useful, but it seems like I get an error after a fresh install. The error occurs whenever a new buffer is open for editing. Based on the output, I'm guessing whenever a buffer is read.

Figured someone else may have a similar issue or have ideas for the solution:

reproduce step:

open vim via vim -u test.vim

type i to insert mode, then type into main<tab>

you will see

AutoComplete not working in sub directory

deoplete-clang2 works great if I edited a file from one parent like src/somefile.cpp but if go beyond that like src/folder/somefile.cpp not working

autofill_neomake causing future self.nvim calls to hang

After running lines 157-159, any call to self.nvim.* will block the thread indefinitely. Naturally this means no completions are made, as execution stops when getting the contents of the buffer. Presumably the async_call is never completing, but I stopped debugging (for now) once I figured out what how to get around the problem.

I am using Neovim v0.2.2 on Windows. I do not have neomake installed.

The 'fix' for me was just to let autofill_neomake = 0.

cannot use close brace key in c++ file

I cannnot use close brace key in c++ file.

Screen Shot

Issue with UltiSnips snippets

I have a snippet that expands

if

if (true) {
	
}

However, when I also use deoplete-clang it expands to

if<Plug>delimitMateS-Tab

instead. The problem persists regardless of my UltiSnips settings, and it doesn't happen with deoplete-clang.

Insert mode `<tab>` cause wrong input.

open new empty c file, nvim main.c
go to insert mode, type <tab>

you will see pumvisible() ? "\" : "" be inserted.

Throws errors when trying to type the name of an `#include`d header

Here are the steps:

Edit the file (nvim derp.c)
Type the following: #include <
Once I start typing the name of the header (e.g. stdio.h) deoplete throws the following errors:

options for this plugins should be detect when deoplete-clang2 is loaded.

@tweekmonster
I have this config in my vimrc, but my deoplete is lazy loaded on Insert mode event. so when I open a cpp file, :Neomake clang still get errors about use of undeclared identifier 'nullptr', after I go into insert mode, :Neomake clang will not show issues, so I think the options below is detect when deoplete is loaded.

let g:deoplete#sources#clang#flags = ['--std=c++11']
let g:deoplete#sources#clang#autofill_neomake = 1

When using the autocomplete on a protected method in a base class, the autocomplete shows an unexpected and unuseful.

It appears this only happens when a base class has a protected method. Everything else seems to appear fine.

Paths to headers get completed but everything else does not

Hey!
I'm just starting out with C++ and making a small project with libcinder. I build it with cmake configuration that Cinder provides. Everything works fine but I can't make auto completion work.

What's interesting is that when I type #include "(...) a dropdown shows me a bunch of vaild options, including Cinder libs like:

#include "cinder/gl/gl.h"
#include "cinder/gl/Batch.h"

But when I try to see stuff in the included namespace typing something like gl::(...)... Nothing. I see only suggestions from buffer source.

My ./compile_commands.json looks like this:

[
{
  "directory": "/home/alex/projects/fixation",
  "command": "/usr/bin/c++  -DFT2_BUILD_LIBRARY -DFT_DEBUG_LEVEL_TRACE -D_GLFW_X11 -D_GLFW_GLX -D_GLFW_USE_OPENGL -D_GLIBCXX_USE_CXX11_ABI=0 -D_UNIX -isystem /home/alex/repos/Cinder/include  -g   -std=c++14 -o CMakeFiles/Fixation.dir/src/Fixation.cpp.o -c /home/alex/projects/fixation/src/Fixation.cpp",
  "file": "/home/alex/projects/fixation/src/Fixation.cpp"
}
]

After running cmake -DCMAKE_EXPORT_COMPILE_COMMANDS=1 my project folder looks like this:

./Debug
./Debug/Fixation
./Makefile
./cmake_install.cmake
./structure.txt
./assets
./CMakeCache.txt

Cannot get autocomplete from the plugin

Interesting fact:
Completion works with no regard for the following globals presence.

g:deoplete#sources#clang#libclang_path="/Library/Developer/CommandLineTools/usr/lib/libclang.dylib"
g:deoplete#sources#clang#clang_header ="/usr/local/Cellar/llvm/5.0.0/lib/clang"

Completion still works although I put this variables in a comment section. Weird!

Disable argument placeholders

Hi, I've been using this instead of deoplete-clang for some time now and it works great, especially for bigger projects. However, I find the argument placeholders annoying and would like to disable them to have the plugin act like other deoplete sources. Would it be possible to add such an option?

placeholder next/prev mapping `<Tab>` interfere with completion pum

I really would like better integration with deoplete, as this completion source was designed for that plugin.
It is very convenient to use only when completing things, however I cannot find a solution to this problem:

When having the following configuration

        let g:clang2_placeholder_next='<Tab>'
	inoremap <expr> <Tab> pumvisible() ? "\<C-n>" : "\<Tab>"

deoplete-clang2's placeholder_next always takes precedence.

TL;DR

It is not possible to continue to the next completion item with <Tab>, because clang2's placeholder jumping algorithm takes over an the currently active item is used.

This worked fine on Gentoo and Arch so I don't know.

`libclang` versus `clang -cc1`

Hi there, thanks for the plugin. I am trying to search a little bit about what is the difference between using libclang or using the clang front end clang -cc1? And only this FAQ.

I've found libclang unreliable with heavy templated code in c++, and happy to explore alternatives.

Any clarification, or link to information would be appreciated. Thanks!
