The only problem I can see with file format is that listings can have a large number of parameters and lexer may not be able to read the whole string. Right now, I save/load/transport parameter strings like
language=Python,float in the form of language=Python!float but ! may (I am not sure) be used in some options. The only solution I can think of is the HTML way, where special characters are encoded in &1023; etc for storage and transportation. Does anyone know how to implement this? If encode decode can be implemented in InsetListingsParams, many heuristic parts of the implementation can be strengthened. I can then claim beta quality of this patch. Cheers, Bo
