Requirements:
- Compilation tools: cmake and g++
Compilation: ./do_compile.sh <build type> [extra cmake arguments here]
Usage: ./build-<build type>/math_input
Modifications:
This version of seshat:
- Has no InkML support anymore (xerces-c dependency removed)
- No longer makes use of boost
- Requires C++23 support in your compiler (std::ranges::iota_view, std::ranges::zip_view, std::ranges::fold_left)
- Or at the very least, C++20 (concepts, std::span) with the ranges-v3 library to add the STL ranges missing from this version
- More modern memory management, less abusive usage of std::list and raw new/delete. Who knows, might make it faster.
- As such, this is pretty much standalone, as long as you have a recent compiler and the Config folder
Fork goals:
To use this in a natural display c++ calculator as an open source Math Input Panel kind of thing.
In this endeavour, the program will be turned into a library that should let you input mouse/touch strokes over time and get a list of possible results, for user selection.
- This step has been completed, the calculator part has not.
