I use company-ycmd as the backend of C and C++. While when I type character such as :: and -> ,the completion begins automatically but I can't input any character because it always reminder me of "Matching input is required". So I have to call company-ycmd manually.

I have ycmd configured to work in C++ buffers and everytime I open a buffer I get asked for a username and password.

(use-package ycmd
  :defer t
  :init
  (add-hook 'c++-mode-hook 'ycmd-mode)
  :config
  (use-package company-ycmd
    :config
    (company-ycmd-setup)
    (add-to-list 'company-backends (company-mode/backend-with-yas 'company-ycmd)))

  (set-variable 'ycmd-server-command '("python" "/Users/patrick/bin/ycmd/ycmd"))
  (set-variable 'ycmd-global-config "/Users/patrick/.ycm_extra_conf.py"))

My ycmd-config file can be found at https://gist.github.com/halbtuerke/66004fbd5730d0dbcb9a

I have ycmd (20150626.109) and company-ycmd (20150514.534) from Melpa installed and I'm using GNU Emacs 25.0.50.1 built 2015-06-19 on OS X 10.10.3.

I installed ycmd the following way:

• Cloned ycmd (796519f7a01ca9b5151d77058ab3985f9f9c2809) to ~/bin/ycmd
• git submodule update --init --recursive
• ./build.py --clang-completer

After pressing C-g to cancel the username prompt this can be found in the Messages buffer:

Contacting host: 127.0.0.1:61158
error in process filter: Quit [2 times]
Contacting host: 127.0.0.1:61158
REQUEST [error] Error (error) while connecting to http://127.0.0.1:61158/healthy.

And this is the ouput of the ycmd-server buffer:

2015-06-29 13:24:29,339 - DEBUG - Global extra conf not loaded or no function YcmCorePreload
serving on http://127.0.0.1:61077
2015-06-29 13:24:30,272 - INFO - Dropping request with bad HMAC.

I found https://github.com/Valloric/ycmd/issues/115 but as described above, I used the latest versions available of everything and unfortunately it does not work.

If you need any additional information please let me know.

We have a lot of C++ files that take a long time (multiple seconds) to incrementally compile. In that case, I get non-optimal behavior from emacs-ycmd: I start writing something, for example: variable I start getting error markers (expected). I continue: variable. Now the problem is that the re-parsing of the file is still running, so I don't get completions. I have to do backspace, '.' multiple times until I happen to get completions. Then, when I finish: variable.something(); The error markers will not go away (it seems like it started the call before I typed ';', and then didn't issues another one when I finally finished writing).

When ycmd takes a while to get the compile commands (for our internal build system this can take a minute or so) or compile command are not available for some other reason (this can be easily tested with a .ycm-extra-config that does not produce compile commands) I get the error: REQUEST [error] Error (error) while connecting to http://127.0.0.1:35282/event_notification instead of a useful error message.

I'm not sure whether that's related to #23 at all (once I wait a while everything works), or whether it's possible to get better responses from emacs-request.

When I open ycmd-mode, there is an error REQUEST [error] Error (error) while connecting to http://127.0.0.1:41211/event_notification.. When trying to type something, ycmd said that Ycmd completion unavailable while parsing is in progress.. I don't know how long does it take to process the completion, but I waited for a long time and still couldn't work.

I try to debug the problem. I found that the ycmd server process was already started. How do I know if my ycmd client can successfully communicate with server?

When I use (company-ycmd-setup) (add-hook 'after-init-hook 'global-company-mode) (add-hook 'prog-mode-hook 'ycmd-mode) (flycheck-ycmd-setup) (add-hook 'prog-mode-hook 'flycheck-mode)

I run into problems with flycheck on emacs lisp files: When I open them, flycheck shows FlyC* in the command line (instead of FlyC:1/4), which apparently means "currently running" forever, and does not display any errors. The flycheck error list is empty. I can get it to work by disabling ycmd (M-x ycmd-mode, then M-x flycheck-buffer, and it works fine).

I finally had time to test everything on Windows. First of all, in Vim YCM works just fine here, so the following problems are most likely related only to your package and not YCM on Windows in general.

I use company-ycmd and I keep getting:

Ycmd completion unavailable while parsing is in progress.

Do you have any ideas why?

ycmd-extra-conf-handler documentation says that it will by default ask whether to load .ycm_extra_conf.py, but it never does like if it cannot find it. In Vim it searches for it bottom-up starting from the directory of the currently edited source file. Is the same true in your case? If yes, then why is it not locating .ycm_extra_conf.py?

Hi,

I'm using: Commit cdeabc17a22661541d5d5d20545a405f14a13a10 of emacs-ycmd (latest master as of this writing) Commit 97c19ffe442683cfff8d68a3d343a8b497ea4fd5 of ycmd (latest master as of this writing) Python 2.7.6 (Ubuntu 14.04) Emacs 24.3.1 (Ubuntu 14.04)

I ran the ycmd testsuite and it didn't reveal any errors, so I suppose the issue is with emacs-ycmd or my configuration of it (~/.emacs.d/init.el): (require 'ycmd) (set-variable 'ycmd-server-command '("python" "/home/mband/ycmd/ycmd")) Where /home/mband/ycmd is the "git root".

When I open a .cpp file I get the following error shown: REQUEST [error] Error (error) while connecting to http://127.0.0.1:57953/event_notification. And the ycmd-server buffer contains: 2014-10-28 13:56:32,896 - DEBUG - No global extra conf, not calling method YcmCorePreload serving on http://127.0.0.1:57953 2014-10-28 13:56:32,988 - INFO - Received event notification Traceback (most recent call last): File "/home/mband/ycmd/third_party/bottle/bottle.py", line 861, in _handle return route.call(*_args) File "/home/mband/ycmd/third_party/bottle/bottle.py", line 1734, in wrapper rv = callback(_a, *_ka) File "/home/mband/ycmd/ycmd/../ycmd/watchdog_plugin.py", line 100, in wrapper return callback( *args, *_kwargs ) File "/home/mband/ycmd/ycmd/../ycmd/hmac_plugin.py", line 54, in wrapper body = callback( _args, *_kwargs ) File "/home/mband/ycmd/ycmd/../ycmd/handlers.py", line 59, in EventNotification request_data = RequestWrap( request.json ) File "/home/mband/ycmd/ycmd/../ycmd/request_wrap.py", line 27, in init EnsureRequestValid( request ) File "/home/mband/ycmd/ycmd/../ycmd/request_validation.py", line 28, in EnsureRequestValid missing = set( x for x in required_fields if x not in request_json ) File "/home/mband/ycmd/ycmd/../ycmd/request_validation.py", line 28, in missing = set( x for x in required_fields if x not in request_json ) TypeError: argument of type 'NoneType' is not iterable And one more INFO - Received event notification traceback that I omitted since it contains the same information just with another timestamp.

If you got anything I should test, please let me know as I really want to get this issue solved. To me it sounds like some sort of protocol issue, but given that the last commit on ycmd was 8 days ago, it doesn't appear to be any newly introduced changes...

I'm not sure whether this is a emacs-ycmd or company problem, so reporting this here first: When completion paths in ycm, there are relevant completions, but when one of them is selected (by pressing enter), the whole path is replaced, leaving only the basename.

For example:

1. typing ./some/path/dir/
2. suggestions file1 file2
3. selecting one of them by pressing enter
4. now the whole path (including the leading ./some/path/dir/) is replaced by file1

(@Valloric fyi)

In some cases when using company-ycmd, the first character will work great but on typing additional characters the popup will get pushed down and to the right.

For me this only occurs with ycmd, company works fine everywhere else. This happens in both Python and C++ mode and occurs with error buttons disabled and enabled. Not sure about other factors in my config that could cause this, I'll keep looking into it.

Screencast: http://cl.ly/2s1F1A2r3l08

Screenshot:

Sometimes I noticed that when ycmd return with an error suddenly the font-locking of the current buffer is gone. It's not only C++ buffers but also other buffers like ibuffer or magit-status. It seems it happens when ycmd return an event_notification error. The current selected buffer looses syntax highlighting. I don't have a 100% repro, thats why I cannot say what exactly happens.

Maybe you have some idea?

Thanks, Peter

Not sure why, but in emacs 28.0.50 this expression is evaluated to t: (multibyte-string-p (encode-coding-string (json-encode "t") 'utf-8 t)) In the previous version of Emacs the result was nil. So this is the same issue as #165 .

To fix this change line: from

(defun ycmd--encode-string (s) (encode-coding-string s 'utf-8 t))))

to

(defun ycmd--encode-string (s) (encode-coding-string s 'utf-8))))

Previously if ycmd-global-config was set to a symbolic link YCMD would not use the global config. By running the name of the file through (file-truename) we get the actual file location and use that for the global config.

Thanks so much for creating and maintaining emacs-ycmd! I really appreciate it!

YCMD now has experimental support for using clangd as the completer. This PR adds support for customizing the JSON file sent to YCMD with the clangd-specific options.

I'm not sure if or how this should be tested so I would really appreciate feedback on that.

Thanks!

I'm not very familliar with the ycmd codebade, but I've tracked down the file in question and it doesn't have RestartServer as a command. using rg, I've found that clangd does have it as a command, don't know if that'll help very much.
