eglot returns "Server not initialized!" #30

Closed junyi-hou closed 3 years ago

junyi-hou commented 3 years ago

Thank you so much for this great package.

I use a nix-based system which means digestif and texlive are installed in non-conventional places. digestif -h suggests that I need to set DIGESTIF_DATA, DIGESTIF_TEXMF, and DIGESTIF_TLPDB variables. However, I do not know what those variables are and for. I was hoping you can show me an example of the values of these variables.

P.S., the installed path of texlive is /nix/store/2mvi6sz0q96kbrz6p8zh2nsn7ays1nwq-texlive-combined-full-2020.20210109 and (the wrapper script) digestif is /nix/store/hckcnvihrgpzkfx166yhpljdsj78bhns-digestif

Is something broken? I believe no extra configuration should be necessary if you are either using the self-installing script or have the kpsewhich command in the PATH.

Thanks for the quick response! Actually this is not about the environment variables. (sorry about the confusion, I should have dig a bit more before I open the issue!) When I connected digestif to a tex file using eglot, I got the following error:

You can try setting (and exporting) DIGESTIF_TEXMF to a suitable directory, which in a more traditional Linux distro would be /usr/share/texlive/texmf-dist.

Can you paste the output of the command kpsewhich -var-brace-value=TEXMF? Thanks!

junyi-hou commented 3 years ago

I set DIGESTIF_TEXMF to /nix/store/2mvi6sz0q96kbrz6p8zh2nsn7ays1nwq-texlive-combined-full-2020.20210109/share/texmf-dist and run kpsewhich -var-brace-value=TEXMF, the output is

/home/lactaid/.texlive2020/texmf-config:/home/lactaid/.texlive2020/texmf-var:/home/lactaid/texmf:!!/nix/store/2mvi6sz0q96kbrz6p8zh2nsn7ays1nwq-texlive-combined-full-2020.20210109/share/texmf-local:!!/nix/store/2mvi6sz0q96kbrz6p8zh2nsn7ays1nwq-texlive-combined-full-2020.20210109/share/texmf-config:!!/nix/store/2mvi6sz0q96kbrz6p8zh2nsn7ays1nwq-texlive-combined-full-2020.20210109/share/texmf-var:!!/nix/store/2mvi6sz0q96kbrz6p8zh2nsn7ays1nwq-texlive-combined-full-2020.20210109/share/texmf

actually, if I remove all the DIGESTIF_* variables, the Server not initialized! error is gone and everything works! I was assuming that I need to set those variables since I installed stuffs in non-conventional ways! :)
