Package: jsane
JSane is a JSON “parser” that makes attribute accesses easier.Three-line intro>>> import jsane
>>> j = jsane.loads('{"foo": {"bar": {"baz": ["well", "hello", "there"]}}}')
>>> j.foo.bar.baz[1].r()
u'hello'MotivationPicture the scene. You’re a jet-setting developer who is obsessed with going to
the gym. One day, a world-class jewel thief kidnaps you and asks you to hack
into the super-secure bank server in thirty seconds, while an ultramodel is
performing oral sex on you. You hurriedly trace the protocol on the wire, only
to discover, to your dismay, that it uses JSON. Nested JSON, with levels and
levels of keys.It’s hopeless! You’ll never type all those brackets and quotation marks in time!
Suddenly, a flash of a memory races through your mind, like some cliche from
a badly-written README. You launch the shell and type two words:import jsaneThe day is saved.Motivation (non-Hollywood version)Are you frustrated with having to traverse your nested JSON key by key?root = my_json.get("root")
if root is None:
    return None

key1 = root.get("key1")
if key1 is None:
    return None

key2 = key1.get("key2")
if key2 is None:
    return None

<five more times>Is your code ruined by pesky all-catchingexceptblocks?try:
    my_json["root"]["key1"]["key2"]["key3"]
except:
    return NoneAre you tired of typing all the braces and quotes all the time?my_json["root"]["key1"[""]][]"]']'"}}""]Now there’s JSane!Motivation (non-infomercial version)Okay seriously,this["thing"]["is"]["no"]["fun"]. JSane lets youtraverse.json.like.this.r(). That’s it.UsageUsing JSane is simple, at least. It’s pretty much a copy of the builtinjsonmodule.First of all, install it withpiporeasy_install:pip install jsaneHere’s an example of its usage:>>> import jsane

>>> j = jsane.loads('{"some": {"json": [1, 2, 3]}}')
>>> j.some.json[2].r()
3You can also load an existing dictionary::>>> j = jsane.from_dict({"hi": "there"})
>>> j.hi
'there'If the dictionary contains any data types that aren’t valid in JSON (like
functions), it still should work, but you’re on your own.Due to Python being a sensible language, there’s a limit to the amount of
crap you can pull with it, so JSane actually returns aTraversableobject on
accesses:>>> j = jsane.loads('{"foo": {"bar": {"baz": "yes!"}}}')
>>> type(j.foo)
TraversableIf you want your real object back at the end of the wild attribute ride, call.r():>>> j.foo.bar.r()
{"baz": "yes!"}If an attribute, item or index along the way does not exist, you’ll get an
exception. You can get rid of that by specifying a default:>>> import jsane

>>> j = jsane.loads('{"some": "json"}')
>>> j.haha_sucka_this_doesnt_exist.r(default="💩")
"💩"“But how do I access a key calledr?!”, I hear you ask. Worry not, I got you
covered:>>> j.key["r"].more_key.r()Confused? Don’t name your keysr, then.That’s about it. I’m not loving ther()API, so if anyone has any good
recommendations on how I may better fulfil my unholy purpose, I’m changing it on
the spot. No guarantees of stability before version 1, as always. Semver giveth,
and semver taketh away.Help needed/welcome/etc, mostly with designing the API. Also, if you find this
library useless, let me know.LicenseBSD. Or MIT. Whatever’s in the LICENSE file. I forget. It’s permissive, though,
so relax.Self-promotionIt’s me, Stavros.FAQDo you find it ironic that the README for JSane is insane?No.Is this library awesome?Yes.I hate the.r()thing, is there any way to avoid it?Did you evenreadthis README?Alright, there is now a way to avoid it. Instead ofj.foo.bar.r(), you can
just call the last key, i.e.j,foo.bar(). Let me know what you think inthe relevant issue.
