Jari still deserves much of the thanks, because this project would not have been possible without him making the PDK Framework source code available. All I had to do was create a Lua wrapper for it, which was easier than you might think. (JW Lua has some undocumented reflection features that made it possible to automate a great deal of the wrapper code.)

I have far too much work for the rest of the year to try it, but given your track record, I have no doubt that this is excellent software.  I just went to your "purchase" page and was amazed that RGP Lua is not listed there.  It's really amazing that both Jari and you make your work on this available for free.

>> This message is to announce the initial release of a new Finale-embedded Lua interpreter called RGP Lua. The reason for this project is that the much-appreciated JW Lua has an uncertain future. It has not been updated since 2017. It is gradually becoming incompatible with new releases of Finale, and it will stop working entirely under a likely imminent release of Finale for Apple Silicon.

(You can use FCCustomWindow instead. It's slightly more cumbersome to use but looks far better.) Also, the setup and development environments are completely different, though simple to use.

>> Moving past Lua 5.2 to...what? To LuaJIT? (LuaJIT is based on Lua 5.1 and appears to be abandoned.) To Lua 5.4? (Lua 5.3 and higher introduce breaking changes in how Lua number to integer conversion happens which has potentially a huge impact on existing JW Lua scripts.) Maybe just stay put?

>> Direct support for the new doc-settings classes in F26.2 and higher.
>> 
>> Addition of missing classes. I'm betting FCTieMods is high on a number of lists. But anything I add will need testing beyond what I can do by myself. In the case of FCTieMods, I worry that there was some reason Jari never implemented it, though I don't see it if there is.

>> Two big enhancements already in RGP Lua are 1) support for Lua 5.2-compatible C libraries and 2) the option to embed luasocket for external debugging or other purposes.
