tram

Tram is a small, dynamically-typed, and tree-walked toy-language resembling a mix of Lua and Python.

The madlibs example in sample/madlibs.tr covers most language features.

history

This language was originally designed and implemented in a week. Then, I recently (oct 2025) spent some time making it more complete.

Overall, I'm very happy with where it was able to get in such a short amount of time.

future work

• a bytecode VM of some sort would be a massive performance improvement. the current tree-walking implementation is likely leaving a lot of performance on the table
• implementation of a strong typing system (interested in making a zig-like comptime typing system in an interpreted language)
• standard library
• better glue between rust functions and tram language functions. maybe a proc macro?

features

• dynamic typing
• small standard library with math functions and constants
• if expressions, not statements
