Cite autocomplete fails

[neilernst]

If I write 'cite_' and hit Ctrl-Space, I get autocomplete for all words with "c" in the document. This document has two bib files if that might be a cause. The other file I tried with only one bib file is fine.

I have the same problem. I tracked it down to @comment entries in my .bib file. These entries are inserted by BibDesk to keep track of reference groups. The lines that cause the problem for me are:

@comment{BibDesk Smart Groups{

The completion code looks for lines that start with @ and then expects to be able to match them with this regexp:

    kp = re.compile(r'@[^\{]+\{(.+),')

which requires a comma at the end of the line. For the comment lines, this crashes producing the error that you are seeing (or at least I get the same message).

I work-around the problem by adding a ? after the comma in the regular expression. This allows completion to work, with a side-effect that the comment prefix is also offered up as a completion.

A proper fix would be to have a more complex check that lines beginning with @ are actually bib entries, not something else such as a comment.

Oh goodness... and I thought I had tamed bib files :-( I can't promise a quick fix but I'll take a look. I am thinking about parsing the file differently for other reasons anyway...

After seeing #50, I wanted to add that my two bib files do not have @comment, but the longer one has a 2 line header

Any changes to this file will be lost if it is regenerated by Mendeley.

and the 'abbr' file is a series of @string entries (these convert 'variables' in bib files to longer strings, e.g. ACM = "Associ. Computing Machinery"

Closing for now, as this may be solved with new parsing code (please be patient)

I suggest the following fast fix (at least, it is working for me):
line 369 of latex_cite_completions.py
keywords = [kp.search(line).group(1).decode('ascii','ignore') for line in bib if line[0] == '@']
should be changed to
keywords = [kp.search(line).group(1).decode('ascii','ignore') for line in bib if line[0] == '@' and kp.search(line)]

Thanks, that solved my problems with Bibdesk generated bib files.
