How about using mygamma to improve code quality
Gamma is an intelligent software analytics platform that supports teams in building high quality software.
You can register for free and scan for 5 times every day up to 1 million code.
I use it to analyze ccls and get a high score(4.45/5) ๐.
If you are interested in it, maybe you can use it. Cheers.

Multiple definition during the linking step
Hi, it's me again. There seems to be some problems of the final linking step:

cquery vs ccls
First of all congratulations for the great work on cquery and ccls.
I would like to ask what are the advantages of using ccls over cquery except the ones in Readme.
For example in the longterm?
Also i would like to ask if there will be better support in the emacs plugin for ccls compared to cquery?

no document format buffer capabaility for ccls?
I tried using lsp-format-buffer inside emacs after configuring lsp-css and to my surprise, lsp-mode threw an error saying that that capability does not exist.
Was this removed after forking from cquery? I remember cquery containing this functionality.
company-lsp crashes ccls.

Foundation/Foundation.h file not found for Objective-C.
I am seeing "Foundation/Foundation.h file not found" error while trying to use ccls to parse an Objective-C file.
I guess I need to use ccls to index built-in Objective-C library source files so that this error goes away. Is it correct?
Thanks!
Thanks for your hard work
As title, cquery/ccls is so awesome, the best c/c++ index tool I have ever seen. Thanks again for your hard work, wish it all the best :)

How about using astyle to format the source code

I have just set ccls up with emacs. I've generated compile_commands, and when I run lsp-ccls-enable from a cc file, caches are created for system headers and the corresponding headers. They are not created for all the other headers from the project that are pulled in.
For example, in foo.cc (lets say it's in the projectroot/base directory), the following headers might exist.
include
#include "foo.h"
#include "base/bar.h"
After lsp-ccls-enable, .ccls-cache has
@usr@include@c++@7@memory and @usr@include@c++@[email protected]
as well as
[email protected], [email protected], [email protected], and [email protected]
I don't get any headers for [email protected] or [email protected] even though these are in the compile commands database.
Can you help me troubleshoot this? Finding references is not very useful with only a fraction of the project indexed and it's even worse for files that fully qualify their own header. If foo.cc had
#include "base/foo.h"
then the header is not indexed at all.

How to escape backslashes?
Even though I thought this is a CMake/Ninja problem, since you have successfully built the ccls on Windows, it will be nice if you can help me around this.
This is my cmake command
cmake . -Brelease -G Ninja -DCMAKE_CXX_COMPILER=clang++ -DSYSTEM_CLANG=On -DCMAKE_PREFIX_PATH="D:\\Programs\\msys64\\mingw64\\lib\\clang\\6.0.0\\"
cmake --build release
I tried both / and \\ to split the path, but didn't help.
This caused the following errors:

ccls returns wrong "kind" for symbol
When browsing C repository (emacs source code, latest), if one makes a "textDocument/documentSymbol" request from emacs, you get back some hash tables with "kind" field set to 255 (maximum this should be is 26, as per https://github.com/Microsoft/language-server-protocol/blob/f46eb9656ad07d25a93e498d9ee3507f71317fb1/versions/protocol-1-x.md#document-symbols)
Steps to reproduce:
- Open emacs C source code in emacs (27.0.50)
- open lisp.h in src directory
- send the following request
M-:
(lsp--send-request
(lsp--make-request "textDocument/documentSymbol"
`(:textDocument
,(lsp--text-document-identifier))))
- go to messages buffer and copy over the hash table returned, inspect values and see that the "kind" field has weird values like 255.
submodule url not invalid
ccls assumes cc is clang
After properly setting up ccls for my project i got a problem from ccls server.
It assumes that cc is clang while on my system it is gcc and it passes some arguments like
-resource-dir=/usr/lib/clang/6.0.0, -fspell-checking, -fparse-all-comments, -working-directory
that gcc does not support and eventually lsp-stderr has this libclang crash detected during parsing
Consider reverting to using ubuntu 14.04 version of clang by default
Just as in jacobdufault/cquery#750
Centos 7 user here (because... reasons). The ubuntu-14.04 clang works fine for me but the ubuntu-16.04 doesn't (it complains that it can't find
GLIBCXX_3.4.20).Maybe 14.04 was a safer default?

Perhaps a find_package() call is missing for an IMPORTED target, or an

ccls can't find subproject header
Hi. I'm trying to configure ccls for my C++ project.
It works really smooths and it is really fast.
However ccls can't detect some header files and I can't figure out that this is caused by my cmake config
or wrong behavior of ccls.
Problems
- ccls cannot complete header file location. (Only cannot find subporject's header files)
- ccls cannot complete class methods which is defined in subproject(I guess this is related to previous issue)
The problem is that ccls failed to detect headers in external subporject in my project. I'm using two subproject currently (fmt and eigen). They are just git submodule from another github repo.
For instance let's say I want to use include fmt/core.h in my project which is located in fmt project.
If I type #include <fm ccls does not suggest any header file candidates in fmt project.

a couple hours ago, ccls was just fine. I tested some basic features under spacemacs.
However, two hours ago, after I recompiled aur/ccls-git and updated lsp-mode, ccls package in emacs, errors occurred!

maybe I could roll back the emacs packages. but I don't know how to downgrade a aur/ccls-gt package.
or should I build ccls by git and compiling the source code?
libclang: crash detected during parsing
Hello,
I am trying to use the ccls with emacs as a replacement for cquery, but it does not work at all. In different projects I always get libclang errors like this:

With cquery the same setup is working properly.
cannot find system C++ header with ccls
system C header and Clang resource directory both complete fine:
Once I change all ccls in my configuration into cquery, C++ header can be also completed fine. So I think the problem arises from ccls
I have noticed this FAQ:
Set Initialization options "cacheFormat": "json" and run jq . < /tmp/ccls/@tmp@c/a.cc.json to see if -resource-dir is correct,
IIRC, (setq ccls-cache-dir ".ccls_cached_index") store the cache. Then I found in root of project(just 1 source file for test, but has cmake and compile_commands.json and cquery do work fine in this project) a .ccls_cached_index folder. There is two folder inseder, @@... and @.... In @@..., there is no json file, opposite filled with:
...
@usr@include@[email protected]@bits@predefined_ops.h.blob @usr@[email protected]
@usr@include@[email protected]@bits@ptr_traits.h @usr@[email protected]
...
However in .cquery_cached_index/@@... folder, there are json files:
...
@usr@include@[email protected]@bits@predefined_ops.h @usr@lib@gcc@[email protected]@[email protected]
@usr@include@[email protected]@bits@predefined_ops.h.json @usr@lib@gcc@[email protected]@[email protected]
I don't if here is wrong.
From this link, I tried it on os:

Error suggestion
Hi,
19:27:39 comp-preload clang_tu.cc:392 E libclang had ast read error for $file. Please try running the following, identify which flag causes the issue, and report a bug. ccls will then filter the flag for you automatically.
c++ ...
It might be worth clarifying this should be clang++ in case c++ defaults to g++.
Why not cquery?
Does it work with Monaco?
Since Monaco editor and VS Code share the same core, and ccls works with VS Code, I wonder if ccls works with Monaco as well?
Thanks for this nice project.
[Feature request] Monaco editor support?
As Monaco editor is rising to a dominance status, I wonder if you have any plan to add some support to it, including adding some instructions on how to make ccls work with Monaco, just like what's done for VS Code?
Thanks for this awesome work!
C++ code completion suggests both private and public class members
When using code completion in neovim (through the LanguageClient-neovim plugin) with ccls, the completion suggestions on an object include both public and private members. For instance, given the class,
class A
{
public:
void myPublicFunction();
private:
void myPrivateFunction();
int private_member_;
};
performing completion on an object a of class A shows myPublicFunction(), myPrivateFunction(), and private_member_ as completion suggestions. In practice, we can't call private members on an object. Is there a way for ccls to only provide completion suggestions for public members, or to note whether a member is public or private? This would be a really helpful addition to code completion.

FR: C designated initializers
Hello, great work with this project, for me it's the holy grail of Vim autocompletion.
ISO C99 added "Designated Initializers": you can give the elements of a struct initializer in any order, by specifying the name of each field to initialize with .fieldname =. For example:
struct VkInstanceCreateInfo inst_info =
{
.sType = VK_STRUCTURE_TYPE_INSTANCE_CREATE_INFO,
.pNext = NULL,
.flags = 0,
//...
};Since each undeclared field is initialized to 0, designated initializers are safer because they avoid undefined behavior caused by uninitialized fields. This feature is only in C.
These initializers are often a lifesaver for me. Would it be possible to add field completion for this?

Is there any need for modern-c++-font-lock-mode?
Hello, I just started using ccls a few weeks ago and I was wondering is there any need for modern-c++-font-lock-mode since ccls also takes care of semantic highlighting using font-lock (does this also support all the latest C++17 stuff)?
Indexing fails on compilation database using 'arguments:' for command line
New user here, could be something I'm doing wrong. I'm using ccls with Emacs on macOS. I built ccls from github clone and installed it in /usr/local/bin. I installed emacs-ccls and lsp-mode packages for Emacs.
When I call M-x lsp-ccls-enable on a project file, it picks up the compilation database fine. The database was generated from clang -MJ option, and it uses "arguments:" key instead of "command:" for the compile command. When the indexer attempts to run on the visited file, it fails reporting a bunch of Error lines in *Messages*. Checking *lsp-ccls stderr* it's reporting an error from clang:
error: unable to handle compilation, expected exactly one compiler job in ' "/path/to/clang" "-cc1" <rest of compile args> ; '
where <rest of compile args> is the rather long set of compile options I've used, omitted for brevity.
Maybe clang is expecting the arguments to be joined into a single command? This would look more like the "command:" key that is the alternative option for the compile db.
Occur error during build.
My system is Ubuntu16.04, I'm trying build ccls as getting started. When I run cmake -H. -Brelease , I got these:

Frome MaskRay/emacs-ccls:
(require 'ccls)
(setq ccls-executable "/path/to/ccls/release/ccls")
After install ccls-git via yaourt, I used locate ccls to look for the path:
400 โฏ : locate ccls โ
/home/chenli/.emacs.d/.cache/quelpa/melpa/recipes/ccls
But I failed. How can I find the path?
Memory requirements.
I am investigating various C/C++ language servers (LS), including ccls. As we are going to run the LS in a memory constrained environment, memory consumption is an important criteria for us when choosing from candidate LS'es.
Suppose I have a setup like this: I have installed standard g++/STL, along with Boost library. How much memory is consumed when ccls parses a simple C/Cpp/ObjC file handling LSP requests, consisting no more than a few hundred lines of code?
I assume indexed files derived from C standard library/STL/Boost are loaded when parsing the client's file, how much memory is required for the indexed files? What if I run multiple ccls instances on one single machine, are these files shared by all the instances, or each instance has to load a copy of these index files?
Thank you.
