You can define custom file-type filters in ripgrep

ripgrep lets you filter files by their language type — e.g. search only C-related files:

$ rg 'int main' --type c

Here the --type value maps to a glob (e.g. c maps to *.{c.h}). You can list all the available types with rg --type-list.

Furthermore you can define your own types such as “web” related files:

$ rg --type-add 'web:*.{html,css,js}'

which lets you search such files with:

$ rg --type=web $QUERY

Even better, define your own types in your $RIPGREP_CONFIG_PATH config file:

# ~/.ripgreprc

--smart-case
--hidden
--glob=!git/*

--type-add=web:*.{html,css,js}
--type-add=django:*.{py,html}
