cite-autocompletion: problem with umlaut in pathname

[jarrndewitt]

I am using vim-latex on windows 10.

I want to use cite-autocompletion within chapter.tex which itself gets included in main.tex in the same directory. The file main.tex.latexmain resides in the same directory.

The autocompletion works without problems except when there are Umlauts (ÄÖÜäöüß) in the pathname. Spaces don't seem to be a problem though.

When I press [F9] vim-latex displays a line "(a) all (f) filter ..." at the bottom and prompts me to press ENTER. When I do that I get back into insert mode where I was before without an empty display of found bib-entries. To me this seems to be the same as if I had removed the bib-file.

However if I type :py Tex_BibFile=bibtools.BibFile("bibliographie.bib") autocompletion works. I have to retype this after every start of vim.

I cannot reproduce this with linux. Can you enable debugging

let g:Tex_Debug = 1
let g:Tex_DebugLog = "vim-latex-suite.log"

and show the log file after trying to complete a \cite{?

[jarrndewitt]

I use the file main.tex

\documentclass{article}
\usepackage{natbib}
\bibliographystyle{dinat}
\begin{document}
\cite{s}
\bibliography{bibliography}
\end{document}

and bibliography.bib

@Article{six,
title = "The Six -- a Boring Number",
author = "Name, Alice and Other, Bob",
journal = "Journal for Testing Affairs",
year = 2066,
volume = 66,
number = 6,
pages = "66--666",
}
@Article{seven,
title = "The Seven -- an Interesting Number",
author = "Name, Alice and Other, Bob",
journal = "Journal for Testing Affairs",
year = 2077,
volume = 77,
number = 7,
pages = "77--777",
}

I have these files once in a directory called A and once in a directory called Ä. Everything else is identical. I now open the file main.tex, enable debugging, put the cursor behing the \cite{s and press [F9].

The log within a path without umlaut:

view : Tex_Complete: s:type = cite, typeoption =
view : :Tex_Complete: using s:prefix = s
view : :Tex_FindBibFiles:

The log within a path with umlaut:

view : Tex_Complete: s:type = cite, typeoption =
view : :Tex_Complete: using s:prefix = s
view : :Tex_FindBibFiles:
proj : texproject.vim: catching LatexSuiteFileType event
env : envmacros.vim: Catching LatexSuiteFileType event

view : :Tex_FindBibFiles: trying to search through [bibliography]
view : :Tex_FindBibFiles: returning [C:/Users/User/Documents/Temp/Ä/bibliography.bib
]

Till now the log looks identical to me (except the changed path of course)

Does

:py Tex_BibFile=bibtools.BibFile("""C:/Users/User/Documents/Temp/Ä/bibliography.bib""")

work?

[jarrndewitt]

That produces

Traceback (most recent call last):
File "", line 1, in

self.addfile(f)

raise IOError(e.errno, e.strerror, e.filename)
IOError: [Errno 2] Das System kann den angegebenen Pfad nicht finden: 'C:\Users\User\Documents\Temp\\xc3\x84\bibliography.bib'

However when I just type :py Tex_BibFile=bibtools.BibFile("""bibliography.bib""") (without the path), cite-completion works afterwards.

Does the command with the full path work if you replace
https://github.com/vim-latex/vim-latex/blob/master/ftplugin/latex-suite/bibtools.py#L11
by

 from urllib2 import urlopen, pathname2url

?

Otherwise I would be very happy if you are able to fix the python code since I am not able to reproduce your error.

[jarrndewitt]

If I do that the next time I open a .tex file I get ImportError: cannot import name pathname2url.

Ok. Maybe one has to fiddle around with the encoding of the filename? The filename is passed to python utf-8 encoded. However, NTFS seems to use utf-16.
