Open Source Projects

CSYS
Cross Platform C++ Console Library

CSYS is a console library that aims to provide all the underlying systems/features a console would need (i.e. auto-complete, commands, etc). This was a summer project developed in collaboration with Tristan Bouchard. 

Responsibilities:
​
- ​Implemented full and partial auto-complete using ternary search trees achieving high performance.
- Implemented command history, script support and command logging functionality.
- Led test driven development writing 110 unit-tests with 80% code coverage.
- Managed continuous integration, build system and unit testing to ensure library correctness and stability.

What I learned:
- CMake - Build system
- Travis/AppVeyor - Continuous Integration
- Doctest - Unit testing
- Ternary Search Trees - Used for auto-complete

​Platforms: Windows/Linux
Language: ​C++

ImGui Console Widget

A Dear ImGui Console Widget built with CSYS. ImGui-Console started as a example/test project for CSYS and something I wish our team had when developing Arc Apellago. I developed all of the features below:

- Smart scrolling, command timestamps, command log filtering and colored console output.
- Console settings and visuals are preserved through sessions.

If you wish to see ImGui-Console in action there is an example executable in GitHub!

What I learned:
- ImGui - User Interface
