jb is a simple Git script that automatically creates and switches to a branch based on a JIRA issue. It uses the JIRA API to fetch the issue number and title, converting it into a suitable Git branch name.

1. Compile the binary:

   go build -o git-jb .

2. Copy the git-jb binary to a directory in your PATH, for example:

   cp git-jb /usr/local/bin/
   chmod +x /usr/local/bin/git-jb

3. Set the required environment variables for JIRA authentication:

   export JIRA_USERNAME="your_username"
   export JIRA_TOKEN="your_token"
   export JIRA_URL="https://your-jira-instance.com"

In a Git repository, run:

git jb ISSUE-123

Where ISSUE-123 is the JIRA issue number. The script:

• Fetches issue details via the JIRA API.
• Creates a Git branch named ISSUE-123-issue-title.
• If the branch exists, it switches to it.
• If the branch does not exist, it creates and switches to it.

• Git
• API access to JIRA
• Environment variables JIRA_USERNAME, JIRA_TOKEN, JIRA_URL
• go-jira library

If a JIRA issue exists:

ISSUE-123: Fix bug in authentication

Then running:

git jb ISSUE-123

Will create or switch to the branch:

ISSUE-123-fix-bug-in-authentication
