pls in Rust. This is yet another PHP language server. It uses
the tree-sitter framework for parsing text into AST. Currently, it only has basic diagnostic features,
such as syntax checking, undefined variables, duplicate namespaces. Other features such as context-aware
auto-complete, diagnostics based on a strong type system, intelligent hover text, will be added at a later
time. I wrote this because other PHP language servers were pretty slow in indexing my files, and usually
caused noticeable slowdowns whenever I requested any auto-complete. After a few updates, they usually had
weird quirks such as highlighting large swaths of template files as errors. pls is different in that,
even though there are issues, they are understandable, and they are my issues, and therefore I don't
complain as much about them.
nlclc-stats via custom site generation in Clojure. This is a client-based web app that shows statistics around worship service in our church. This is an experiment in the amount of framework you need to build a website, without just typing everything in HTML. Thus, the entire site can be viewed without any Javascript (though having Javascript would improve functionality).
superdiff in Rust. This is a CLI app that can find similarities in file(s). It is mainly used to check for copy-pasted code. We don't use treesitter here because I wanted it to be language-agnostic. Instead, we use edit distance to determine similarity. Supports multi-threading and is pretty darn fast.
Rocket 2 in Python with mypy type-checking, hosted with auto ci/cd with Inertia and docker-compose. This is a web app that provided HR tools for the UBC Launch Pad engineering club.
Jeopardy in Typescript and vue.js. This is a client-based web app that allows you to play Jeopardy-type games. This game is intended to be used in screen-share software or on some projector.
Graph Visualizer in Javascript.
Tom's Parable in C# with Unity. This is a short Windows-only 3D FPS game where you play the role of a detective. This game was created as a group project for the TWU CS course "Intro to VR".
