Interpreters

This apps/ directory is set aside to hold interpreters that may be incorporated into NuttX.

Ficl

This is DIY port of Ficl (the Forth Inspired Command Language). See http://ficl.sourceforge.net/. It is a DIY port because the Ficl source is not in that directory, only an environment and instructions that will let you build Ficl under NuttX. The rest is up to you.

Lua

Fetch and build a Lua interpreter. Versions 5.2 through 5.4 are supported. The lua command will be added to NSH. Lua can run a script for a given path, execute a string of code, or open a readline compatible REPL on the NSH console. The <lua.h> and <lauxlib.h> headers are available to start a new embedded interpreter or extend Lua with C modules. See the luamod_hello example for how to include a built-in module.

A math library is required to build. Enable the LIBM config or use a toolchain provided math library.

The following configs are recommended for a full featured Lua interpreter:

• LIBC_FLOATINGPOINT
• SYSTEM_READLINE
