[Message part 1 (text/plain, inline)]

Here it is an example: If we oversimplify json parsing consist of 2 parts.

1. JSON parsing to Jansson data structures
2. Converting Jasson data structures to lisp data structures.

If we assume that 1 is taking most of the time then we could write the
following code:

start(string, callback) -> convert string to char* -> post it to worker
thread -> worker thread does the parsing
-> worker thread post to main loop -> main loop converts Jansson ds to lisp
ds -> main loop
calls the callback passed on start

The same strategy probably could be applied to Font locking with
TreeSitter.

Thanks,
Ivan
