interoperability issues with vim-gitgutter
I'm on commit 66ab8e0a356ea8a971e99156c59d09c3beae5ef2 of errormarker, and the latest version of gitgutter (256702d).
I'm using Debian/testing built VIM v8.2.
I have been using gitgutter and errormarker plugins for a while. Gitgutter would manage git-diff markers in the left margin, while errormarker highlights lines with errors in red after running :make.
A recent update (in gitgutter) prevents errormarker from showing the highlight. Even if I use :GitGutterLineHighlightsDisable.
NOTE: I have also filed this as an issue on vim-gitgutter: https://github.com/airblade/vim-gitgutter/issues/806
As suggested in https://github.com/airblade/vim-gitgutter/issues/806#issuecomment-942365388, the problem can be resolved by adding
let g:gitgutter_sign_priority = 5
