DepHub Core

Set of libraries, providing functionality for managing (read-only) dependencies for PHP and Python package managers.

❗ The package is in active developement. Methods may and will change over time until the first major release (1.*). Then the project will follow semantic versioning rules.

Packages

There are several useful packages included:

• API wrappers for fetching additional information on packages (package README.md):
  • Packagist API
  • PyPi API
• Source fetchers (package README.md)
• Dependency files parsers (package README.md)
• Versions and constraints parser with checking logic (/providers/versioneer)

Main dephub module

This module provides functionality for fetching, parsing and working with different package managers files and services.

Fetching dependency managers files

Dependency source represents abstraction over package manager source files and provides convinient interface to fetch packages information.

Usage example (retrieving Composer constraints list):

// import "github.com/dephub/dephub-core/dephub"

// We should define the source where our dep files are stored, in this example we will use the Git source.
// The last argument can be blank.
source, err := dephub.NewGitSource(http.DefaultClient, "git@github.com:laravel/framework.git", "master")
if err != nil {
    panic(err)
}

// Get all the constraints for Composer from the source.
constraints, err := source.Constraints(context.Background(), dephub.ComposerType)
if err != nil {
    panic(err)
}

fmt.Printf("Random constraint from \"laravel/framework\" composer.json: %q:%q \n", constraints[0].Name, constraints[0].Version)
// output: Random constraint from "laravel/framework" composer.json: "psr/simple-cache":"^1.0"

Packages updates checking

Dependency checkers allow you to check constraints and requirements and get new/updatable versions information for them.

Usage example:

source, _ := dephub.NewGitSource(http.DefaultClient, "git@github.com:laravel/framework.git", "master")
constraints, _ := source.Constraints(context.Background(), dephub.ComposerType)

updatesChecker := dephub.NewComposerUpdatesChecker(http.DefaultClient)
incompatibleOnly := true
updates, err := updatesChecker.LastUpdates(context.Background(), constraints, incompatibleOnly)
if err != nil {
    panic(err)
}

firstUpdate := updates[0]
fmt.Printf("Package %q (current constraint %q) has new version %q, get info on %q", firstUpdate.Name, firstUpdate.CurrentConstraint, firstUpdate.Version, firstUpdate.URL)
// output: Package "monolog/monolog" (current constraint "^2.0") has new version "2.2.0", get info on "https://github.com/Seldaek/monolog.git"
