Go Composer Lock Parser

Basic Composer lockfile parser library written in Golang.

Usage

Initalise the composerInfo object, and use the Parse(filepath) method to read the Composer lockfile and unmarshal it into the object defined in parser.go.

The library defines two helper methods for convenience:

1. GetPackageByName()
2. GetPackageListByPrefix()

The first one will return the Package which has exactly the name as specified, while the second will return a []Package, where the name starts with the given string.

For example the following code will parse a composer.lock file in the project, find a project called "drupal/embed", and also find all drupal specific projects.

func main() {
  c := new(composerInfo)
  c.Parse("/path/to/composer.lock")

  // Get a single package by name.
  p := c.GetPackageByName("drupal/embed")
  fmt.Println(p)

  // Get a list of packages by the prefix.
  pList := c.GetPackageListByPrefix("drupal")
  for _, p := range pList {
    fmt.Println(p.Name)
  }
}
