# go-srcinfo

A golang package for parsing `.SRCINFO` files. [SRCINFO](https://wiki.archlinux.org/index.php/.SRCINFO)

go-srcinfo aimes to be simple while ensuring each srcinfo is syntactically
correct. Split packages and architecture specific fields are fully supported.

# Examples

Reading a srcinfo from a file
```go
package main

import (
	"fmt"
	"github.com/Morganamilo/go-srcinfo"
)

func main() {
	info, err := srcinfo.ParseFile("SRCINFO")
	if err != nil {
		fmt.Println(err)
		return
	}

	fmt.Println(info)
}
```

Reading each package from a split package
```go
package main

import (
	"fmt"
	"github.com/Morganamilo/go-srcinfo"
)

func main() {
	info, err := srcinfo.ParseFile("SRCINFO")
	if err != nil {
		fmt.Println(err)
		return
	}

	for _, pkg := range info.SplitPackages() {
		fmt.Printf("%s-%s: %s\n", pkg.Pkgname, info.Version(), pkg.Pkgdesc)
	}
}
```

Showing the architecture of each source
```go
package main

import (
	"fmt"
	"github.com/Morganamilo/go-srcinfo"
)

func main() {
	info, err := srcinfo.ParseFile("SRCINFO")
	if err != nil {
		fmt.Println(err)
		return
	}

	for _, source := range info.Source {
		if source.Arch == "" {
			fmt.Printf("This source is for %s: %s\n", "any", source.Value)
		} else {
			fmt.Printf("This source is for %s: %s\n", source.Arch, source.Value)
		}
	}
}
```

Reading a srcinfo from a string
```go
package main

import (
	"fmt"
	"github.com/Morganamilo/go-srcinfo"
)
