🎯 GetDirectDependencyNames

Gets the list of direct dependency package names, equivalent to running composer show --direct and parsing the output.

When to use

Use it when you only care about dependencies explicitly declared in composer.json (excluding transitive dependencies). Commonly used for generating concise dependency reports or checking whether direct dependencies are outdated.

Signature

func (c *Composer) GetDirectDependencyNames() ([]string, error)

Parameters

This method takes no parameters.

Return value

Return value	Type	Description
First return value	[]string	List of direct dependency package names
Second return value	error	Returned when executing composer show --direct fails

Example

package main

import (
	"fmt"
	"log"

	"github.com/scagogogo/composer-skills/pkg/composer"
)

func main() {
	comp, err := composer.New(composer.DefaultOptions())
	if err != nil {
		log.Fatalf("initialization failed: %v", err)
	}

	direct, err := comp.GetDirectDependencyNames()
	if err != nil {
		log.Fatalf("failed to get direct dependencies: %v", err)
	}
	fmt.Printf("%d direct dependencies in total:\n", len(direct))
	for _, name := range direct {
		fmt.Println(" -", name)
	}
}

Advanced

• To get all installed packages (including transitive dependencies), use GetInstalledPackageNames.
• To get a summary of direct dependencies, dev dependencies, and installed packages at once, use GetProjectDependencies.
• To read the raw require field of composer.json, use ReadComposerJson.
