Script used to setup the above.

#!/usr/bin/env bash

set -e

# get first argument
if [ -z "$1" ]; then
    echo "No argument supplied"
    exit 1
fi

# check if directory exists
if [ ! -d "$1" ]; then
    git clone [email protected]:onflow/$1.git
fi

# create workflow directory
mkdir -p ./$1/.github/workflows

cp ./flow-cli/.github/workflows/add-issues-to-devx-project.yml ./$1/.github/workflows/

# go to directory
cd $1

# create new branch only if it doesn't exist already
git checkout -b add-issues-to-devex-project

# add new workflow
git add .github/workflows/add-issues-to-devx-project.yml

# commit changes
git commit -m "Add workflow to add issues to devex project"

# create pr via GH CLI
gh pr create --title "Add workflow to add issues to devex project" --body "Add workflow to add issues to devex project"
