Disinterested with the options for calculator apps on Linux, and frustrated with using Google Search as my primary calculator, I created my perfect calculator: RCalc. Written in C++ using GLFW and Dear ImGui, RCalc is a lightweight RPN calculator that supports scalar types as well as vectors and matrices, and over 80 different operators. To support the over 450 implementations of these operators, I designed a comment-parser-plus-code-generator in Python to enable an almost Elixir-like development experience, reducing my workload by nearly 3x. RCalc can run on Linux, Mac OS, and Windows, either graphically or in the terminal, or as a library to be used anywhere such as in a native iOS app, all from one code base.
Description
Technologies Used
- C++
- Python
- Swift
- Dear ImGui
- FTXUI
- SwiftUI/UIKit
RCalc is multi-platform and runs on Mac OS, Linux, and Windows, with native OS integration.
RCalc is multi-modal and can also run in a completely text-based environment, such as over SSH or when there is no display server.
RCalc's core engine can be embedded in other applications, such as this iOS app.
RCalc heavily uses the python-based SCons build system to generate C++ code at build time, parsing comments to embed descriptions and examples for each supported operator.
