Activating extension 'Julia' failed: Cannot read properties of undefined (reading 'indexOf')

[ASaragga]

Bug Description:

Installed the Julia extension. When I open Theia IDE I get the following notification: Activating extension 'Julia' failed: Cannot read properties of undefined (reading 'indexOf'). I have correctly defined the executable path in the Julia extension. Perhaps consequence of that I am unable to "Julia: Run File in New Process", "Julia: Debug File in New Process" or "Julia: Execute active File in the REPL". All the Julia extension commands I tried appear to be totally ignored.

Steps to Reproduce:

1. Install Julia
2. Install the Julia Extension
3. Define the executable path in the Julia extension
4. Write a short Julia script and save it, e.g: println("Hello Theia")
5. In the Command Palette try a command to run the script, e.g: "Julia: Execute active File in the REPL".

Additional Information

• Operating System: macOS: 15.2
• Theia IDE Version: 1.57.100 (1.57.100.190)

Thanks for reporting, @ASaragga! I can indeed reproduce the issue with the Julia extension.
Here is a detailed log on activating the extension:

From what I could read from https://github.com/julia-vscode/julia-vscode/blob/2ed90c228422854b4748fa3963c76fa9e4125bb9/src/interactive/repl.ts#L1325, it looks like Theia does not have the preference commandsToSkipShell defined as it is in vscode. (see https://github.com/microsoft/vscode/blob/3920366966c2649d3022c205b52dfb6410016a23/src/vs/workbench/contrib/terminal/common/terminalConfiguration.ts#L390).
I moved this issue to Theia framework, where these preferences are defined.

Since the root of the problem has already been identified (a missing preference) just wanted to +1 (Ubuntu 24.04.1 LTS).
But also maybe any direction of what would be involved (repos, modules) in addressing this? It doesn't look like🤞 a hard problem, but jumping to new code base/project takes time (or maybe I should just ask Theia AI to fix it 😄 )

@r23j5a The missing preference mentioned above should likely be entered in here. Ideally, the behavior associated should also be implemented in a PR that contributes the definition of the preference, but is not strictly necessary to fix this issue. Any help is appreicated :)

[r23j5a]

@msujew I can at least confirm that adding the missing preference fixes the problem (fyi master...r23j5a:theia-activating-extension-julia-failed:master it's not doing anything and description was just copied from vscode repo)
