Can't get input value.

Hi,

I'm barely new to Github action and try to make your awesome project work. I tried to make it as simple as possible.

First, I have a repo with my Go code which contains a Go project, simple main.go (and go.mod / go.sum). Here is my main, pretty straightforward, similar as your project's README. It takes an input and set a time value as output.

package main

import (
	"fmt"
	"time"

	"github.com/sethvargo/go-githubactions"
)

func main() {

	user := githubactions.GetInput("who")
	fmt.Printf("User : %s\n", user)

	time := time.Now()
	githubactions.SetOutput("time", time.String())
	fmt.Printf("Time : %s", time)
}

In the same repo I have an action.yml file which describe how to run it :

name: "Say hello"
description: "Github Action to say hello"

inputs:
  who:
    description: 'User to say hello'
    required: true 
outputs:
  time:
    description: 'The time we said hello'

runs:
  using: composite
  steps:
  - name: Build 
    working-directory: src/
    run: go build -o ../bin/main
    shell: bash
  - name: Run
    working-directory: bin/
    run: ./main
    shell: bash

In another repo I try to make it works with a workflow file like this :

name: Go

on:
  push:
    branches: [ main ]
  pull_request:
    branches: [ main ]

jobs:

  build:
    name: Build
    runs-on: ubuntu-latest
    steps:
    - name: Check out code into the Go module directory
      uses: actions/checkout@v3

    - name: Set up Go 1.19
      uses: actions/setup-go@v3
      with:
        go-version: 1.19
    
    - name: Checkout code action
      uses: actions/checkout@v2
      with:
        repository: me/myrepo
    
    - name: Go example
      uses: me/myrepo@main
      with:
        who: 'John Doe'

All steps run fine, but "who" input can't be retrieved.

Here are the logs for Go example build step :

Run me/repo@main
Run go build -o ../bin/main
go: downloading github.com/sethvargo/go-githubactions v1.1.0
go: downloading github.com/sethvargo/go-envconfig v0.8.0
Run ./main
User : 
Time : 2023-01-27 08:15:35.300536781 +0000 UTC m=+0.000578302

Output is nicely set but I can't figure out why user is empty.

Inputs in composite actions are only available via the YAML syntax inputs.who-to-greet - they are not passed into the actual process. You can see this if you look at the value of the environment (env) inside the job.
