tab-key code completion with julia

[daviehh]

Description

Julia allows for unicode in e.g. variable names, entered with latex code or similar: ref.
For example, \Delta + tab key will transform it to Δ in the julia REPL console or in the jupyter notebook without jupyterlab-lsp installed.

However, with jupyterlab-lsp enabled, the jupyter notebook/lab will not do the transform to unicode, but suggest other /-commands

Reproduce

1. Enter \Delta in a cell with julia (IJulia.jl) kernel
2. Pop-up suggests codes related to \Delta, but does not do the replacement to Δ

Expected behavior

\Delta + tab gives Δ

Thank you for opening the issue. This will be fixed in the next patch release. In the meantime you could try disabling 'pre-filter matches' option:
