✅ IsInstalled

Checks whether the current Composer instance already points to a valid Composer executable path. It only checks whether the path is non-empty and does not verify that the executable can run correctly.

When to use

Use this to confirm whether the instance is ready before invoking commands, or to decide whether to trigger the installation flow. Note that it does not execute a Composer command; it only inspects the instance's internal state.

Signature

func (c *Composer) IsInstalled() bool

Parameters

This method takes no parameters.

Return value

Return value	Type	Description
Single return value	bool	Returns true when the instance has a bound executable path, otherwise false

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)
	}

	if comp.IsInstalled() {
		fmt.Println("Composer is ready ✅")
	} else {
		fmt.Println("Composer is not ready ❌")
	}
}

Advanced

• To ensure Composer is installed (and auto-install if necessary), use EnsureInstalled.
• To get the bound executable path, use GetExecutablePath.
• To perform detection + installation + initialization in one shot, use QuickSetup.
