This is a Latex Completer for YouCompleteMe.
It completes citations (\cite{}) and references to labels (\ref{}). It is based
on an old version of vim-ycm-tex
that was using Linux commands to extract labels and bibliography IDs.
-
YCM completers need to be made available in your YCM directory. There's a subdirectory
$HOME/.vim/bundle/YouCompleteMe/third_party/ycmd/ycmd/completers/tex.
This completer should be added in the tex directory (create it if it does not exist) -
The completer will look for a .bib file to determine the main directory of your project. When this is done, it is able to walk through every subdirectory to index labels and bib ids.
-
You need to add a semantic completion part in your .vimrc:
let g:ycm_semantic_triggers = {
\ 'tex' : ['{']
\}To enhance the popup completion with part of the title and authors, we use the bibtexparser module from this repository.
This allows YCM to display a popup like this :
turing:1935 On Computable Numbers... (Turing Alan)
knuth:1984 Literate Programming (Knuth Donald E.)
You can install the bibtexparser via easy_install or pip
sudo pip install bibtexparserIf the bibtexparser is not present on the system, the completer will fallback into the bibid only mode displaying only bibids in the completion popup.
Of course:
- Your .tex and .bib files should be in UTF-8.
- You absolutely need to have a .bib file, because that is how the completer is able to determine the main directory of your .tex project.
