This allows you to define your configuration in a YAML file and then render an output file based on a template input file where your configuration can be expanded. It optionally can load Nunjucks addons like the ones from the companion [Nunjucks Addons](https://github.com/rse/nunjucks-addons) package. Installation & Usage -------------------- For the installation via Node Package Manager (NPM) use: ```sh # plain functionality $ npm install -g @rse/nunjucks-cli $ nunjucks [...] # with addon functionality $ npm install -g @rse/nunjucks-cli @rse/nunjucks-addons $ nunjucks -e @rse/nunjucks-addons [...] ``` Alternatively, instead of globally installing it, you can also use it on-the-fly with NPM's npx(1) utility: ```sh # plain functionality $ npx --yes @rse/nunjucks-cli [...] # with addon functionality $ npx --yes --package @rse/nunjucks-cli --package @rse/nunjucks-addons -- \ nunjucks -e @rse/nunjucks-addons [...] ``` Furthermore, instead of using NPM at all, you can also use Docker (at least as long as you are working with stdin/stdout or perform the corresponding bind-mounts): ```sh $ docker run -i --rm ghcr.io/rse/nunjucks-cli [...] - ``` Finally, there are [pre-build binaries](https://github.com/rse/nunjucks-cli/releases) available, too.
