Papaj REPL - MrKaszeba19/PapajLang GitHub Wiki

Papaj REPL is a read–eval–print loop environment of PapajScript, which is a built-in component of Papaj (previously RPN Calculator).

History

Since November 2018 (version v.0.4.1) Papaj (previously RPN Calculator) has its REPL. Since v.0.5.0 REPL is a separate subsystem within Papaj. Its goal is to be a console environment that allows writing PS commands on-the-spot and run the PS scripts.

Features

  • Papaj REPL may be accessible via Desktop shortcut, if you create it via executing the script installREPL.sh (Unix/Linux) or installREPL.bat (Windows)
