pcalc — docs

pcalc evaluates arithmetic expressions straight from the shell.

$ pcalc "3 * (4 + 2) / 2"
9

Supports + - * / %, parentheses, and floating point. Build with CMake:

cmake -B build && cmake --build build

Potatoly — docs

A tiny ASCII companion that idles in a terminal pane and reacts over time.

$ potatoly --spud
  ( ^_^ )   feed me with `potatoly feed`

Runs anywhere with a standard C++17 toolchain.

p-Root — docs

A no-build static site. Drop the files on any static host and you're done.

python -m http.server   # local preview
