Step by Step Guide to Building a Travis CI API Integration in Python

Introduction

Hey there, fellow developer! Ready to supercharge your CI/CD workflow with some Python magic? Today, we're diving into the world of Travis CI API integration using the nifty TravisPy package. Buckle up, because we're about to make your Travis CI experience smoother than a freshly deployed production build!

Prerequisites

Before we jump in, make sure you've got:

• A Python environment (3.6+ recommended)
• A Travis CI account with an access token (grab one from your Travis CI settings)

Got those? Great! Let's roll.

Installation

First things first, let's get TravisPy on board:

pip install travispy

Easy peasy, right?

Authentication

Now, let's get you authenticated. It's as simple as:

from travispy import TravisPy
t = TravisPy.github_auth("Your-Travis-CI-Access-Token")

Boom! You're in.

Basic API Operations

Let's start with some basics:

# Get user info
user = t.user()
print(f"Hello, {user.login}!")

# List repos
for repo in t.repos(member=user.login):
    print(repo.slug)

# Get build info
build = t.build(123456)  # Replace with a real build ID
print(f"Build {build.number}: {build.state}")

See how easy that was? You're already a Travis CI API ninja!

Advanced Operations

Ready to level up? Let's trigger some actions:

# Trigger a build
repo = t.repo('your-username/your-repo')
t.builds.restart(repo.last_build_id)

# Cancel a build
t.builds.cancel(build.id)

# Restart a build
t.builds.restart(build.id)

Power moves, my friend. Power moves.

Handling Pagination

Dealing with lots of data? No sweat:

for build in t.builds(slug='your-username/your-repo', iterate=True):
    print(build.number)
    # This will automatically handle pagination for you

Error Handling

Sometimes things go sideways. Here's how to stay cool:

from travispy.errors import TravisError

try:
    build = t.build(999999999)  # Non-existent build
except TravisError as e:
    print(f"Oops! {e}")

Best Practices

• Respect rate limits: Travis CI has them, so don't go wild with requests.
• Cache when possible: Save frequently accessed data to reduce API calls.

Example Use Case: CLI Tool

Let's put it all together in a simple CLI tool:

import argparse
from travispy import TravisPy

def main():
    parser = argparse.ArgumentParser(description="Travis CI CLI")
    parser.add_argument("--token", required=True, help="Travis CI API token")
    parser.add_argument("--repo", required=True, help="Repository slug")
    parser.add_argument("--action", choices=["status", "restart"], required=True)
    args = parser.parse_args()

    t = TravisPy.github_auth(args.token)
    repo = t.repo(args.repo)

    if args.action == "status":
        print(f"Last build status: {repo.last_build_state}")
    elif args.action == "restart":
        t.builds.restart(repo.last_build_id)
        print("Build restarted!")

if __name__ == "__main__":
    main()

Conclusion

And there you have it! You're now equipped to wrangle the Travis CI API like a pro. Remember, with great power comes great responsibility – use your newfound skills wisely!
