Advanced

Structured results

When you need field-level data, use ShowPackageInfo instead. It runs composer show pkg --format=json internally and parses the output into *PackageInfo.

Specifying a format

ShowPackageWithFormat(packageName, format) lets you specify the json / text output format:

output, err := comp.ShowPackageWithFormat("symfony/console", "json")
