Support for LSP request semantic tokens (LSP 3.16/vscode-languageclient 7.0.0) #19827
Description
Is your enhancement related to a problem? Please describe.
I tried to use Language client from the npm package vscode-languageclient in che 7.25 and nightly che (on May 18). In both cases, it failed, since Language client 7.0.0 requires vscode version 1.52.0, but theia provided only version 1.50.
Describe the solution you'd like
Seamless integration of the semantic tokens request via the package vscode-languageclient 7.0.0
Describe alternatives you've considered
I also tried vscode-languageclient 6.1.4, which contains WIP proposed version of semantic tokens. On nightly version, it did not yield any results, on 7.25, some semantic tokens were shown, but overall it did not work.
Further, I would like to ask, what is the ETA on described feature (1 month? 1 year? will it ever be supported?).
Where could I check the the current version of vscode that che-theia reports to plugins?
Is it possible that this issue will be solved "simply" by che-theia conforming to vscode 1.52.0 (or higher) API? Or will there be some work specific to semantic tokens needed?
Thanks!
