Testscript highlighting in Neovim

Thu, 09 Apr 2026 20:38:06 +0200

This is a good article on how to use testscript in Go(lang). It also goes as far as adding a syntax file. But I’m 100% into Neovim, so this needs to be tree-sitter grammar on my system.

Well… this was a journey and I needed claude.ai for a lot of stuff to pull it off. I also wanted to insert Go syntax highlighting for Go blocks, like in this file.

This is working on Fedora 43 and Ubuntu 26.04 and depends on a up-to-date tree-sitter-cli as this is the main way of generating the parser.

Matchup in Neovim for Go templates

Sat, 07 Dec 2024 12:04:24 +0100

After dealing with Go templates (also HTML templates) for more than a year and keep loosing track of where each block {{end}}s I finally did something about it.

But that didn’t work that good. So I’ve switch to the match-up plugin, which is better than the built-in matchit that I was using previously. With Neovim I’m using this setup:

Plug 'andymass/vim-matchup'

And this extra bit of config:

require'nvim-treesitter.configs'.setup {
  matchup = {
    enable = true,
  },
}

This in itself does not make template matching work, for this I just copied the Hugo template matcher (which is just like Go templating) to the correct place. Doing this with some automation from inside Neovim:

Nvim Debian Pkg

NVIM stopped making Debian packages a while back, so here is a short note on how to do this yourself. Had a hard time finding this info, hence reproduced here. Assuming you’ve got the source.

make CMAKE_BUILD_TYPE=Release
cd build && cpack -G DEB
sudo dpkg -i nvim-linux64.deb

… and of course you then find the authoritative text.

If you use RelWithDebInfo an ever growing log file will be created in ~/.local/state/nvim/log.
