TL:DR ; results

DukTape is a C engine for executing ECMAScript 5.1ish. (… or JavaScript or whatever we’re calling it this week) Notably, it’s distributed as a trio of source files to ease integration.

Lua is a C script engine (for the Lua languages) and is not distributed in such a nice way. So I spent a few hours preparing a (Python) script to repack Lua 5.3.3 into a single header. (By the time I fix my blog posting stuff 5.3.4 will probably be out)

Merry (belated) Christmas!

Why would you do this?

Mostly to conform to Sean Nothings Barret’s constraints.

Who would care?

Anyone who wants to slap (somewhat) minimal Lua into a project and see what happens.

How did you do this?

I used a python 3.5.1 script to crack open the .tar.gz file, scan the Makefile, then concatenate sources as needed

• I scan for some test cases that you (obviously) won’t have - sorry
• You’ll need a .c (not .cpp … sorrynotsorry) file for Lua to actually compile … so there’s that.
• … my tests are written in .cpp though … as is the Catch unit testing framework …
• I used a regex and POSIX line endings to get the whole thing under 1MB
  • so that KDiff likes it
  • … hopefully, future updates won’t break this
