Thanks.

It can. The cli can handle json5 (https://json5.org/) so trailing commas and comments are a-ok.

And yes, re: jayk. Almost certainly. :)

It has been an ambition of mine to turn this into a c lib to parse/process the syntax into an AST so it can be used in multiple languages... but I haven't been able to set the time aside for that particular batch of work, yet.

  Peggy: Parser generator for JavaScript

  

Thanks. Yes, DTL's core textual syntax is described with PEG. I make use of the Peggy (https://peggyjs.org/) PEG processor to build up the AST that is used to actually process DTL.

There are C based PEG processors, which I've looked at once or twice also, but I haven't sat down to try to convert it. Mostly out of a desire to get the existing module to work well. A working module for one language is better than a partially working module for multiple. :P
