View Source Md.Parser behaviour (md v0.7.6)
Interface to implement for the custopm parsers.
Custom parsers might be used in syntax declaration when the generic functionality is not enough.
Let’s consider one needs a specific handling of links with titles.
The generic engine does not support it, so one would need to implement a custom parser
and instruct Md.Parser to use it with:
# config/prod.exs
config :md, syntax: %{
custom: %{
{"![", MyApp.Parsers.Img},
...
}
}Once the original parser would meet the "![" binary, it’d call MyApp.Parsers.Img.parse/2.
The latter must proceed until the tag is closed and return the remainder and the updated state
as a tuple.

Types
The type to be used in all the intermediate states of parsing.
Callbacks
Takes a not parsed yet input and the state, returns the updated remainder and state.

@type parsing_stage() :: {binary(), Md.Listener.state()}
The type to be used in all the intermediate states of parsing.
The first element iof the tuple is the continuation (not parsed yet input,) and the latter is the current state.

@callback parse(binary(), Md.Listener.state()) :: parsing_stage()
Takes a not parsed yet input and the state, returns the updated remainder and state.
