jupyterlab-latex: Synctex fails on windows

Jupyterlab 0.32.1 jupyterlab_latex 0.3.0 MikTex 2.9.6500

It appears that it is searching for files in the wrong location. (note the ‘uri’ in the traceback)

From the server console after clicking “scroll pdf to cursor” on the .tex fail:

Uncaught exception GET /latex/synctex/gryoscope.pdf?page=1&#35;x=0&y=0&1525389931568 (127.0.0.1)

gyroscope.(tex/pdf/synctex.gz) are all in the same folder (at the base of the directories accessible given where I started the server)

Hi @t-makaro, I’ve just published a new release of the python package (v0.4.0) which uses absolute paths for the SyncTeX requests. In my testing, this appears to resolve the issue. Let me know if that fixes things for you, and thanks for your patience!

Okay, I can reproduce this on Windows, but not on Linux. It seems the issue is with the SyncTex being extremely picky about absolute vs relative paths in the file names passed to it, and some versions of synctex don’t accept relative paths at all.

This discussion is helpful in working this out. It will be a pain, but I think it is fixable. I must say, SyncTeX’s CLI is not very robust.

Okay, I have confirmed the bug, and will have a fix shortly. Thanks for helping with this @t-makaro!
