Configuration

As lol use viper the parameters can be provided not only by flags but also be read from config file (lol.yaml, lol.toml, lol.json...) or/and from environment variables (starting with LOL_).

Using config file

You can provide all default values for flags in a config lol file in the current folder. For example if your project needs xelatex and use imgs/logo.png you can save the following lol.yaml in the current folder

Compiler: xelatex
Patterns:
  - imgs/logo.png

Using environment variables

If you wan to provide global default values you can set an environment variable. For example if you want by default to use ytotech service you can set LOL_SERVICE=ytotech.
