English | 简体中文

formulas-calculator is a small MoonBit CLI powered by FrozenLemonTee/LunarFormulas and FrozenLemonTee/LunarUnits. It evaluates cataloged physics formulas with unit-bearing inputs.

#Usage

During development, run the command through moon:

moon run cmd/main -- list
moon run cmd/main -- show force
moon run cmd/main -- calc force --mass "2 kg" --acceleration "3 m/s^2"
moon run cmd/main -- calc ohm-voltage --current "2 A" --resistance "3 Ohm"

Output format:

moon run cmd/main -- --format si calc force --mass "2 kg" --acceleration "3 m/s^2"
moon run cmd/main -- --format latex calc force --mass "2 kg" --acceleration "3 m/s^2"

#Commands

list: list shipped formula names, domains and display equations.
show <name>: show a formula's metadata, inputs and output dimension.
calc <name> --<input> <quantity>: evaluate a formula with named inputs.
