# Library for creating Woodpecker CI plugins

Provides basic structure and helpers to load Woodpecker CI environment variables while also
supporting reading Drone CI environment variables where available.

Adds logging support based on [zerolog](https://github.com/rs/zerolog) library and allows configurable
HTTP client library.

## Builtin settings

| Settings Name | Environment variable | Default | Description |
|---|---|----|---|
| `log_level` | - | `info` | Sets log level (`panic`, `fatal`, `error`, `warn`, `info`, `debug`, `trace`) |
| `skip_verify` | - | `false` | - | Skip verification of TLS certificate |
| | `SOCKS_PROXY` | *none* | SOCKS5 proxy to use for connections |
| | `SOCKS_PROXY_OFF` | *none* | Do not use SOCKS5 proxy |

## Creating plugin

```go
package main

import (
	"context"

	"codeberg.org/woodpecker-plugins/go-plugin"
	"github.com/rs/zerolog/log"
	"github.com/urfave/cli/v2"
)

type Settings struct {
	// TODO: Plugin settings
	SampleFlag string
}

type Plugin struct {
	*plugin.Plugin
	Settings *Settings
}

func (p *Plugin) Flags() []cli.Flag {
	return []cli.Flag{
		// TODO: Add flags
		&cli.StringFlag{
			Name:        "sample.flag",
			Usage:       "sample flag",
			EnvVars:     []string{"PLUGIN_SAMPLE_FLAG"},
			Destination: &p.Settings.SampleFlag,
		},
	}
}

func (p *Plugin) Execute(ctx context.Context) error {
	// TODO: Implement execution
	log.Debug().Msg("executed")
	return nil
}

func main() {
	p := &Plugin{
		Settings: &Settings{},
	}

	p.Plugin = plugin.New(plugin.Options{
		Name:        "sample-plugin",
		Description: "Sample plugin",
		Flags:       p.Flags(),
		Execute:     p.Execute,
	})

	p.Run()
}
```
