Bug ID: 515874
Summary: Vala LSP client failing to autocomplete and format
files
Classification: Applications
Product: kate
Version First 25.12.2
Reported In:
Platform: Flatpak
OS: Linux
Status: REPORTED
Severity: major
Priority: NOR
Component: scripting
Assignee: [email protected]

Target Milestone: ---
SUMMARY
On the latest version of Kate (25.12.2) The Vala LSP (vala-language-server
0.48.7) doesn't work and cannot autocomplete using the LSP plugin.It seems to
start properly in the output window, only difference I noticed is a couple of
warning whenever it opens a document. It works properly on Kate 25.08.3
Here are the following warnings:
(vala-language-server:69510): vls-WARNING **: 09:58:21.469:
compilation.vala:297: Compilation(): Error reading file
?/media/italocapasso/NVME/workspace_vala/veggies?: Is a directory
[09:58:21  Servidor LSP Registro]
vala@/media/italocapasso/NVME/workspace_vala/veggies
(vala-language-server:69510): vls-WARNING **: 09:58:21.469: server.vala:539:
[textDocumnt/didOpen] failed to open - Error reading file
?/media/italocapasso/NVME/workspace_vala/veggies?: Is a directory
(vala-language-server:69510): vls-WARNING **: 09:58:21.469: server.vala:544:
[textDocument/didOpen] could not open
There are more warnings before this (some vala-CRITICAL messages and a
uninitialized notification not being handled), but those have always been there
(and vala-language-server should fix those i believe). But these are the are
the new warning that show up in Kate 25.12.2, and maybe linked to
vala-language-server not working.
The Vala LSP server does work properly without any issue in 25.08.3.
STEPS TO REPRODUCE
1. Open any Vala meson project via open folder.
2. Open any .vala file
3. Wait for the LSP to initialize
4. Watch the warning messages in the output window
5. Try to trigger autocomplete, it never shows up anywhere and noting happens.
6. Invoke the LSP format command, it doesn't work either.
OBSERVED RESULT
Autocomplete symbols don't show up and formatting does not occur.
EXPECTED RESULT
Autocomplete symbols should show up and formatting should happen.
SOFTWARE/OS VERSIONS
Linux: Elementary OS 8.1
Platform: Flatpak
Vala LSP: vala-language-server 0.48.7
ADDITIONAL INFORMATION
The vala LSP (vala-language-server) does work properly without any issue in
25.08.3.
I am not sure if this is a Kate issue or a vala-language-server issue,
especially if there has been any updated to the LSP protocol or similar that
warrant the vala-language-server to be updated as well. But my hunch is that
the issue lies within Kate.
Any insights here would be very useful.
Thanks a lot,
