Here is a Proof Of Concept patch against my development tip on what's
involved in getting the JSON lexer not to need a nul-terminated string
to parse. This passes regression, incidentally. The downside is that
processing is very slightly more complex, and that json_in() would need
to call strlen() on its input. The upside would be that the processing
routines I've been working on would no longer need to create copies of
their json arguments using text_to_cstring() just so they can get a
null-terminated string to process.
Consequent changes would modify the signature of makeJsonLexContext() so
it's first argument would be a text* instead of a char* (and of course
its logic would change accordingly).
I could go either way. Thoughts?
cheers
