File Interpretation

Pass a path to a .lisp file and rontolisp interprets it directly, without producing any compiled artifact. The file's top-level forms are read and evaluated in order on the tree-walking interpreter, sharing one environment, so a function or variable defined near the top is available to everything below it.

rontolisp program.lisp

Unlike the REPL, a script does not echo the value of each form -- output is whatever the program writes explicitly with print, format, and the like. The process exits with status 0 when the file runs to completion, or non-zero if a form signals an error.

Example (program.lisp):

This is the same source you would later hand to the JVM or WASM compiler; running it through the interpreter first is the fastest way to check a program's behavior before compiling it.
