ARGV::JSON - easy JSON handling in one-liners #perl

Perl

To manipulate JSON data with perl-oneliner I have been writing like this:

% perl -MJSON -0 -E 'say decode_json(<>)->{foo}' data.json

... which tires my fingers. Recently I found ARGV::URL, which may be useful for one-liners, so I wrote the JSON-version of this module, ARGV::JSON.

With this module you can simply use <> to access the data structure that the JSON represents.

% perl -MARGV::JSON -E 'say <>->{foo}' data.json

Each <> (readline) call returns a hashref or something. Like jq with Perl, pretty simple.

Multiple JSONs are returned in order:

% echo '{"x":1}{"x":2}{"x":3}' | perl -MARGV::JSON -n -E 'say $_->{x}'
