🔧 EnsureInstalled

Ensures that Composer is installed; if not installed and AutoInstall is enabled, it automatically installs and re-checks.

When to use

Call it at program startup to guarantee a usable Composer for subsequent commands. It is a "lazy" initialization, more flexible than auto-installing at construction time, and suited to deferred initialization scenarios.

Signature

func (c *Composer) EnsureInstalled() error

Parameters

This method takes no parameters.

Return value

Return value	Type	Description
Single return value	error	Returns nil if already installed; returns an error if not installed and AutoInstall is off, or if installation fails

Example

package main

import (
	"fmt"
	"log"

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

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

	if err := comp.EnsureInstalled(); err != nil {
		log.Fatalf("ensure installation failed: %v", err)
	}
	fmt.Println("Composer is ready ✅")
}

Advanced

• For an installation progress callback, use EnsureInstalledWithProgress.
• To detect, install, and initialize in one step, use QuickSetup.
• To only check whether Composer is installed (without triggering installation), use IsInstalled.
