Modeline is broken

[rihardsk]

Description

After spacemacs upgrade and package upgrade, modeline doesn't show anything in the active window, it's just a blank line. Every other window (non-focused) shows stuff as expected, though. In *Messages* I get

Error during redisplay: (eval (spaceline-ml-main)) signaled (void-function treesit-available-p) [45 times]

which seems related.

Reproduction guide 🪲

I have the same problem. I update spacemas + all packages every morning, yesterday things worked, now they don't. Spacemacs itself didn't change, but the package update pulled in 3 new package versions:

• centered-cursor-mode-20230911.1503 => centered-cursor-mode-20230914.1358
• helm-20230909.1649 => helm-20230919.442
• helm-core-20230910.424 => helm-core-20230916.1702

Rolling back those packages make the modeline work again, so it must be a new bug in one of those packages.

Same here.

Spacemacs ver. 0.999
Emacs ver. 29.1

Last thing I did before logging off yesterday was to update with update-packages.

Today I open my Emacs session and the modeline is empty.

If I call find-file the modeline reappears, at least until I quit the Helm window.

Warnings thrown

Error during redisplay: (eval (spaceline-ml-main)) signaled (void-variable treesit-inspect-mode) [9 times]
Error during redisplay: (eval (spaceline-ml-main)) signaled (void-variable treesit-inspect-mode) [5 times]

Same here.

Temporary fix that I use, disable treesiter-inspect using spaceline-toggle-treesit-inspect-off function.

The bug is coming from spaceline-segments.el package.

The upstream issue is closed TheBB/spaceline#240, updating to latest spaceline resolves the issue. Closing.
