# Free Tables: A Conduit for the Magic of Python #

##################################################

Python data types are awesome. You can do pretty much anything with them.
One particularly useful arrangement is a list of dictionaries, something
I started referring to as a "free table."

This is a library for manipulating free tables.

################# Setup
    $ sudo python setup.py install

That's it really. Python's pretty rad. Future versions may be a little more 
complicated.

################# Conventions
data: If an argument is called data, a free table is expected there.

datum/point: A dictionary of a free table. 

dex: If an argument is called dex, then it should be a dex--a dictionary
whose values are free tables. These are what indexBy returns. 

prop: If an argument is called prop, it's a property. This usually should
be an entry in every datum in data. It isn't always, sometimes intended for
retaining consistency. 

################# FAQ
+ Why don't you make an ftable class?
    No. That defeats the whole point of free tables. They're supposed to be
    pliable and easily manipulable using Python syntax. They're a convention,
    not a type. I only see the imposition of a class upon the structure as
    a hinderance.

    Additionally, free tables are the gestation of a larger movement towards 
    a classless society free of bourgeoisie oppression. This is because 
    algorithms are ideology. Power to the people.

    If you think I'm wrong, you're welcome to prove me so.


################# Official To-Do/Bugs List

Bugs:
    + load_csv is a half-baked implementation. No quote support.

To-Do/Ideas (No Particular Order):
    + multidex seems to be superslow--optimizations required.
    + validate
    + a version of validate that doesn't raise an error, but instead
        just returns naughty and nice lists.
    + fill_defaults
        - given a default entry, it fills each data point that lacks
            a key in default with the kv pair in the default.
    + dump_csv
        - both load_csv and dump_csv need to be totally written to handle
            dialects more formally
    + load_json, dump_json - I don't use json enough for this, but it's easy.
    + indexBy4's performance really dragged once pipe was fixed. Further
        optimizations: change pipe's default from lambda x: x to False and
        create two cases.
    + mv(("x","y"), [{"x":...}, ...]) -> [{"y":...}, ...]
    + has - remove values that don't have property
    + fulldex: build a dex of every value available. crazy? absolutely.
    + kmap(data, k, f)
        d[k] = f(d[k])
    + tag is so useful, but it's hideous. why is it so wrong? 
        - too expressive, perhaps


################# Version Info
0.2.7:
    + speed boost (probably) for multidex (removed "sum(...,[])")

0.2.5 - 0.2.6: 
    + ???
    + multidex
    + shoulda had better verison notes here, sorry.

0.2.4:
    + flatdex 
        - dex entries with one member are turned into the dex dictionary values.
            {1: [{"x":1}]} -> {1: {"x":1}}
        - force = False
            - if IS True, it grabs the first entry of each list

0.2.3:
    + indexBy0 wins the optimization war. Removed alternatives.
    + Added index, which swaps the arguments of indexBy
    + singletons("label", [1,2,3]) -> [{"label": 1}, {"label": 2}, ...]
    + removed pprint statement from merge

0.2.2:
    + There's load_csv and dump_csv functions now, but they are crap. They work.
        But they're crap.
    + This fixes the ";" bug from earlier versions.

0.2.1: 
    + version number is now a string so I can support multiple "."s

0.21:
    + indexBy4: ACTUALLY fixed pipe arg. The last fix was sloppy.
    + indexBy0 is now the winner again, so that's the default now.

0.2:
    + Finished tag.
    + Added merge.
    + Cancelled pickle_load/pickle_dump.
    + Cancelled transformAllTo (what was it supposed to do?)
    + indexBy4: pipe arg fixed--may not work properly on others

0.1: 
    + First test version
    + indexBy0, indexBy1, indexBy2, indexBy3, indexBy4 added.
    + indexBy4 selected as optimal.
        Performances:
        <function indexBy0 at 0xf6e500> 0.00283553865387
        <function indexBy2 at 0xf6e6e0> 0.00355636643664
        <function indexBy3 at 0xf6e758> 0.0116692264226
        <function indexBy4 at 0xf6e5f0> 0.00204977947795
    + meta functions 
        Added: 
            future: raises an exception when a planned function is called.
        Planned:
            validate
    + Manipulation functions 
        Added: 
            histo: turns a dex into a histogram (dictionary with number values)
            summary: performs histo on each possible key
        Planned:
            tag
            transformAllTo
    + Hello and Goodbye functions
        Planned:
            pickle_load, pickle_dump
            dump_csv
            load_json, dump_json
        Added:
            load_csv: turns a csv into a free table
