Programming for fun and profit

A blog about software engineering, programming languages and technical tinkering


I always have a few side projects going. The one I'm currently most invested in is RepoBee.


RepoBee is a tool for managing Git repositories on GitHub for education. It can do things like generate repositories for students, clone student repositories in batches, run tasks on the cloned repositories as defined by plugins, and more. I'm really quite proud of it, and have some exciting things coming up for it this summer (that I can't yet talk about).


Labelbot is a small GitHub bot that I developed with a classmate for a course on DevOps and Automated Testing. A problem that occured during the course was that students, who only had read access to the course repository, couldn't label issues with labels such as collaboration_wanted or question. The idea of Labelbot is to allow any user with read access to label an issue through markup in an issue body, that is then checked against a list of allowed labels. If a requested label is allowed, Labelbot will set it on the issue on behalf of the requester, which hopefully reduces the effort of repository maintainers in keeping issues properly categorized. The video below shows a small example of this.

It incorporates a lot of fun technologies, such as continuos integration, continuous deployment to AWS Lambda as well as interaction with the GitHub API using secure tokens. It's usable as is, but is more a proof-of-concept than anything else, and it is unlikely that we will keep developing it.


clanimtk is a fun little framework that I developed a while back. It helps in developing simple command line animations for programs with functionality that take enought time for users to have to be reminded that the program is still running. clanim is a library that contains some example animations created with clanimtk. Below is one of the more advanced animations I created.

I never got as far with it as I would have liked, but what's there is still usable and required some non-trivial use of some of Python's awesome language features.
