Merge

Use a custom merge command

By default, chezmoi uses vimdiff. You can use a custom command by setting the merge.command and merge.args configuration variables. The elements of merge.args are interpreted as templates with the variables .Destination, .Source, and .Target containing filenames of the file in the destination state, source state, and target state respectively. For example, to use neovim's diff mode, specify:

~/.config/chezmoi/chezmoi.toml

[merge]
    command = "nvim"
    args = ["-d", "{{ .Destination }}", "{{ .Source }}", "{{ .Target }}"]

Hint

If you generate your config file from a config file template, then you'll need to escape the {{ and }} as {{ "{{" }} and {{ "}}" }}. That way your generated config file contains the {{ and }} you expect.
