-------------------------------------------------------------------------------- 1 | Pkl Config Adapter for Caddy 2 | ================================ 3 | 4 | This plugin allows you to use [Pkl](https://pkl-lang.org) to configure Caddy. 5 | 6 | **REQUIREMENTS:** This package uses Apple's official Go bindings, which spawns a child process, so the `pkl` command must be [installed](https://pkl-lang.org/go/current/quickstart.html) on your system. 7 | 8 | ## Install 9 | 10 | Install with [xcaddy](https://github.com/caddyserver/xcaddy). 11 | 12 | ``` 13 | xcaddy build \ 14 | --with github.com/caddyserver/pkl-adapter 15 | ``` 16 | 17 | ## Usage 18 | 19 | Specify with the `--adapter` flag for `caddy run`. 20 | 21 | ``` 22 | caddy run --config /path/to/pkl/config.pkl --adapter pkl 23 | ``` 24 | -------------------------------------------------------------------------------- /go.mod: -------------------------------------------------------------------------------- 1
