RGP Lua

RGP Lua is an environment to run scripts written in the Lua programming language as plugins in Finale. It is free and compatible with all 64-bit versions of Finale. It is intended as a successor to the very successful JW Lua plugin, which unfortunately has not been updated since 2017.

RGP Lua includes the following features.

RGP Lua has the following limitations with respect to JW Lua.

With the exception noted above (UserValueInput), scripts that run in JW Lua are compatible with RGP Lua. Most of the existing documentation for JW Lua is still relevant. The following links access that documentation and then offer some pages of revised documentation relevant to RGP Lua.

There are lively discussion groups for Finale-embedded Lua at the JW Lua email list and the JW Lua Facebook page.
