Join the #publiccode channel Get invited

A Go parser and validator for publiccode.yml files.

publiccode.yml is an international standard for describing public software, which should be placed at the root of Free/Libre and Open Source software repositories.

This parser performs syntactic and semantic validation according to the official spec.

Features

  • Go library and CLI tool (publiccode-parser)
  • Supports the latest version of the publiccode.yml Standard
  • publiccode-parser can output validation errors as JSON or in errorformat friendly way
  • Verifies the existence of URLs by checking the response for URL fields (can be disabled)

Example usage as a library

parser, err := publiccode.NewDefaultParser()

// error handling

publiccode, err := parser.Parse("file:///path/to/local/dir/publiccode.yml")
// OR
// parse.Parse("https://github.com/example/example/publiccode.yml")

Validation from command line

The publiccode-parser binary which be used for validating a publiccode.yml from the command line.

To get the latest development version use:

go install github.com/italia/publiccode-parser-go/v4/publiccode-parser@latest
publiccode-parser mypubliccode.yml

To get the latest stable version go to the release page and grab the one for your arch.

Run publiccode-parser --help for the available command line flags.

The tool returns 0 in case of successful validation, 1 otherwise.

Easy validation with Docker

You can easily validate your files using Docker on your local machine or in your CI pipeline:

docker run -i italia/publiccode-parser-go /dev/stdin < publiccode.yml

The image is available on Dockerhub. You can also build your own running:

docker build -t italia/publiccode-parser-go .

Examples

The examples assume that your publiccode.yml file is on your local machine, at /home/my-user/publiccodes/publiccode.yml

  • Validate and print the canonicalized file

    docker run -i italia/publiccode-parser-go -export /dev/stdout /dev/stdin < publiccode.yml

  • Validate a publiccode file named publiccode.yml in /home/user

    docker run -v /home/user:/go/src/files italia/publiccode-parser-go

  • Validate a publiccode file named /opt/publiccodes/my-amazing-code.yaml

    docker run -v /opt/publiccodes:/go/src/files italia/publiccode-parser-go my-amazing-code.yaml

  • Validate publiccode.yml without using the network (fe. checking URLs are reachable)

    docker run -v /opt/publiccodes/publiccodes:/files italia/publiccode-parser-go -no-network publiccode.yml

  • Debugging, access the container interactive shell, overriding the entrypoint

    docker run -it --entrypoint /bin/sh italia/publiccode-parser-go
