TinyExpr
TinyExpr is a lightweight, open-source C library for parsing and evaluating mathematical expressions from strings at runtime. It provides a simple API to compile expressions into bytecode and execute them efficiently, supporting basic arithmetic, functions, and variables. It is designed for embedded systems, scripting engines, or applications needing dynamic math evaluation without heavy dependencies.
Developers should use TinyExpr when they need to add expression evaluation to C/C++ projects with minimal overhead, such as in embedded devices, configuration files, or calculators. It is ideal for scenarios where linking to large libraries like Lua or JavaScript engines is impractical, offering a fast and portable solution for parsing user-input formulas or dynamic calculations.
