C-family commit b564b5d doesn't recongnize functions

[snorez]

OS: ubuntu 16.04

Today I update ycm to the latest b564b5d, and download llvm_clang 4.0.1, then rebuild ycm_core. I have done this several times.

When all done, I tried a .c file.
printf, then trigger ycm, it shows printf v or printf [id].

I have to set the HEAD back to 19a6a55. use llvm_clang 4.0.1, rebuild, ycm works very well.

I don't see the problem. Could you explain it better?

[micbou]

Are you using the <C-Space> key to trigger semantic completions? If so, what is the value returned by the command:

:imap <C-Space>

?

[snorez]

@micbou sorry for responding late.
here is my ycm configs

I don't know how to explain it, cause ycm didn't give any error messages.
the differences between them is

printf|

"|" where ths cursor is. then trigger ycm, on my system, I press "\\"(twice), I set <leader> = backslash.
b564b5d shows:
printf v or printf [id]. :YcmDebugInfo and some other commands have no err.
before b564b5d, I was using 19a6a55, which shows

printf( const char *restrict __format, ... )
__PTHREAD_RWLOCK_INT_FLAGS_SHARED
fprintf( FILE *...
...

Thanks, I understand the issue now. Since PR #2657, YCM doesn't set its omnifunc (youcompleteme#OmniComplete) anymore, so your mapping:

inoremap <leader><leader> <C-x><C-o><C-p>

invokes the default Vim omnifunc ccomplete#Complete instead of YCM semantic completion. You need to set the g:ycm_key_invoke_completion option to your <leader><leader> mapping:

let g:ycm_key_invoke_completion = '<leader><leader>'

[micbou]

Also, this line:

inoremap <expr><CR> pumvisible()?"\<C-y>":"\<CR>"

in your vimrc, that closes the completion menu when pressing enter, won't work anymore. You need to replace it with the g:ycm_key_list_stop_completion option:

let g:ycm_key_list_stop_completion = ['<C-y>', '<CR>']

You can remove <C-y> from the list if you don't use it.

@micbou thank you so much, I thought something missing but there are so many commits between these two. I just try the newest one, and modify these two lines, it works now. Thanks again.
BTW, is there a place/file we could find the infomation(e.g. some options are obsolete or changed) when we update ycm (like CHANGED)?

[micbou]

No, there isn't. We may consider adding a changelog file in the future.
