Current std.stdio is deprecated. This ad-hoc should works.
auto json = File("fileName")
.byChunk(1024 * 1024) //1 MB. Data cluster equals 1024 * 4
.map!(ch => ch.idup)
.joiner
.map!(b => cast(char)b)
.parseJSON;

Hi.
What's the best way to pass the contents of a file to the
stream parser without reading the whole thing into memory
first? I get an error if using byLine because the kind of
range this function returns is not what the stream parser is
expecting.
There is an optional filename argument to parseJSONStream, but
I am not sure what this is for, since it still requires the
first argument for the input if the filename is passed.
Thanks.
Laeeth.
some more suggestions for enhancements here:
https://github.com/s-ludwig/std_data_json/issues/12
a big advantage of languages like python is that there are
end-to-end examples of using the language+libraries to
accomplish real work. (they don't need to be more than a
screenful of code, but for the newcomer having it all set out
makes a big difference). since I believe a significant reason
for people to switch to D will be a realisation that actually
CPU time isn't free, it makes sense to be accommodating to
people who previously used scripting types of languages for
these jobs.
