Languages Team L-Train Targets

[tsmaeder]

A place to keep track of issues describing L-Train related items

Beta (Feb 5.)

• LS and Debuggers as remote Theia plugins
  Since all Theia plugins are remote plugins, this item comes down to making language servers and debug adapters run as Theia plugins. Packaging language servers and their native dependencies as a Che plugin is up to the individual plugin.
  One of the issues here is that debuggers may try to launch the debuggee (not the debug adapter) in the container they are in, which is bogus. This means running vscode debug extensions is not generally a solution.

  • Languages API [plug-in] Languages API eclipse-theia/theia#2341
  • Provide Plugin API for contributing Debug Adapters Provide Plugin API for contributing Debug Adapters eclipse-theia/theia#2990
  • LSP client wrapper for Theia LSP client wrapper for Theia #11468
  • How to send/receive messages (e.g. extended protocol like "progress") to and from contributed language servers?
  • TextMate grammars? (part of package.json, see https://github.com/evidolob/theia-docker-plugin)

• Java LS and Debugger as plug-in (Java Language Plugin Java Language Plugin eclipse-theia/theia#3778)

  • both plugins need to have a shared file system (debugger plugin needs to contribute bundles to jdt.ls)
  • java plugin needs API's:
    • Label provider
    • Commands API
    • Menu API
    • ApplyWorkspaceEdit API
  • Need to make or find an appropriate base image for jdt.ls-based tools
  • Publish a che plugin with Theia Java plugin + image

• TypeScript LS and Debugger as plug-in

  • Nodejs Debug Adapter Plugin Nodejs Debug Adapter Plugin eclipse-theia/theia#3766, Che 7 plugin: Nodejs debugger #12409
