Failing to properly install texlab alongside jupyterlab-latex & jupyterlab-lsp ?

[valentin-poncet]

Hello all,

What I am trying to achieve :

I enjoy jupyter a lot, support the free and open standards philosophy. I use it for my data analysis in python and I like it, and would like now to do my document editing in it.

Thus I am trying to turn jupyterlab into a latex IDE like Overleaf. I want to be able to compile, find code piece from pdf and vice versa, and have decent auto-completions.

Steps I followed :

[From Fedora Silverblue with layered texlive-scheme-full]

I installed mamba with miniforge3-linux-64

Then,
mamba create -n latex
mamba activate latex
mamba install 'jupyterlab>=4.1.0,<5.0.0a0' jupyterlab-lsp jupyterlab-latex texlab chktex

I did not install tectonic since I already have a texlive install.

Then ,
jupyter lab --generate-config

Inside the generated file, I added :

c.LatexConfig.latex_command = 'xelatex'
c.LatexConfig.shell_escape = "allow"
c.LatexConfig.bib_command = 'biber'
c.LatexConfig.run_times = 2

–––––––––––––––––––––––––––––––––––––––––––––––––––––

What troubles me:

I was expecting out-of-the-box auto-completions. Like the one showcased on https://github.com/latex-lsp/texlab/

However I have to call it with tab, then it lists (alphabetically ?) the « best » propositions and when I select one it pastes it where I pressed tab. If it’s a \begin it does not add the \end with proper environment (like showed in texlab demo) :

What extra-steps I should take to get it working like showed ?

Fiddling with the json settings editor ?
Is it unachievable on jupyter ?

Here is my packages list in case it’s any useful.
