# Matchup in Neovim for Go templates


After dealing with [Go templates](https://pkg.go.dev/text/template) (also HTML templates) for more
than a year and keep loosing track of where each block `{{end}}s` I finally [did something about
it](https://mastodon.cloud/@miek/113606613003828116).

But that didn't work that good. So I've switch to the
[match-up](https://github.com/andymass/vim-matchup) plugin, which is better than the built-in
`matchit` that I was using previously. With Neovim I'm using this setup:

```vim
Plug 'andymass/vim-matchup'
```

And this extra bit of config:

```lua
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](https://github.com/andymass/vim-matchup/wiki/The-match-up-wiki#hugo)
(which is just like Go templating) to the correct place. Doing this with _some_ automation from
inside Neovim:

```vim
let vim_after=expand('~/.config/nvim/after/ftplugin')
if !isdirectory(vim_after)
  silent execute "!mkdir -p ~/.config/nvim/after/ftplugin"
  silent execute "!cp ~/.dotfiles/after/* ~/.config/nvim/after/ftplugin/"
endif
```

## Update 2025-05-11

I have since moved to a full Lua config in neovim (using a bit of [NvChad](https://nvchad.com)). My
config now looks like:

In `lua/plugins/vim-matchup.lua`:

```lua
return {
	{
		"andymass/vim-matchup",
		event = { "BufReadPost" },
		config = function()
			vim.cmd([[
                let g:matchup_matchparen_enabled = 0 " when 1 this causes lualine flickering
                let s:block_start = '\(define\|block\|with\|range\|if\)'
                call matchup#util#append_match_words(
                       \ '{{-\?\s*' . s:block_start . '.\{-}\s*-\?}}'
                       \ . ':{{-\?\s*end\s*-\?}}')
                call matchup#util#append_match_words('{{:}}')
            ]])
		end,
	},
}
```

And `lua/plugins/init.lua` - a NvChad thing(?), in the treesitter config:

```lua
                ...
                ....
				"vim",
				"vimdoc",
				"yaml",
			},
			matchup = { -- see vim-matchup.lua
				enable = true,
			},
		},
	},
```
