Ahh, those word "transpiler" was new for me
Previously I had to transpile quite a lot of own and other forked plugins.
I would recommend 2 things:
A) For Syntax update only:
1)
[VBS] Simple Regexp Syntax updater
2) There is also TOG's converter, me with Silvers ported to standalone EXE
here. But, be attentive. It is sometimes cut the code entirely from the beginning or middle.
B) To move to using methodmaps:
1)
MethodMapize by Peace-Maker, here is a batch file for easier using attached (you can create a shortcut for it in Win+R Shell:SendTo folder for easy access with Right mouse button -> SendTo).
2) More advanced
version on PHP by Silvers.

Surely, many things are required to be adjusted manually after using those tools.
