Reader generalization #169

Open TotalVerb opened 8 years ago

TotalVerb commented 8 years ago

After #165, to implement #168 properly still requires reader support. A similar analogous as done for writers can be done for readers also. The big roadblocks here are:

unlike for writers, there's no unified Base parsing/reading API; https://github.com/JuliaLang/julia/pull/16981 seems to start on this
for writers, the monadic-style composition is clear; for readers, this is less clearcut

TODO list:

168 Reading NaN and Inf (support parser with added custom tokens NaN and Inf)
170 Reading JavaScript functions (after seeing token function, run custom parsing function)
130 JSON string literal with interpolation (support parser with added custom token $, after which Julia parser is run)

Any progress on this in the meantime? I need to handle a Python-generated file that contains both NaN as a number (violating the JSON spec) and "NaN" as a string. Currently, I'm using Python's parser via PyCall to get around this, but obviously I'd rather like to avoid that.
