Autocompletion / suggestions partially working

[vonAlenberg]

I'm new to Theia and have no idea how to fix it... or if it's normal behavior.

In VSCode:

• Create a test.c file and type main => editor suggests a snippet with a complete main function.
• Create a test.java file and type main => same result.
• Create a test.tex file and type \ => many commands are shown to insert.

In Theia (based on the full image, with added Latex Workshop / texlive):

• Create a test.c file and type main => no suggestion.
• Create a test.java file and type main => works like in VSCode.
• Create a test.tex file and type \ => no suggestions.

My questions:

• Why?
• How to fix?

@vonAlenberg based on your findings and with a little bit of manual testing, it looks like you are not running the same extensions in vscode and theia.

Create a test.c file and type main => editor suggests a snippet with a complete main function.

The following use-case also does not work in vscode unless the cpptools extension is included. You can verify by running vscode with extensions disabled, and retrying your use-case.

Create a test.tex file and type \ => no suggestions

The following worked for me when using LaTeX Workshop extension in theia:

Thanks, for your reply!
That's interesting, because my latest.pakacges.json contains

"vscode-builtin-cpp": "https://github.com/theia-ide/vscode-builtin-extensions/releases/download/v1.39.1-prel/cpp-1.39.1-prel.vsix",

so I thought it would be the same as cpptools in VSCode.

Regarding LaTeX, how did you install the extension? I did via extensions page in theia, so not "pre-bundled" with package.json, maybe that's my mistake?

No, vscode-builtin-cpp is the builtin C/C++ support from vscode which contributes syntax-highlighting mostly. Additional extensions are required to have richer C/C++ support.

I initially added it to my package.json but it's also not working properly for me.
If it is still the case for you please open an issue with steps to reproduce.
