__NOTE:__ This is mostly a spec at this point. I have jison wired up to parse some sample text, but that's it so far.

The idea is to have a reactive notes app that can do math for you using data tables and maybe some python-like functions.

- .txt or .md format
- workflow like Quip?
- should feel like soulver but with table data + functions
- more functional like Calca
- live data tables, importable from .csv, Google Docs, .xls
- custom syntax
- custom JS parser or just use python?
- kind of like iPython 2.0?
  - http://nbviewer.ipython.org/github/ipython/ipython/blob/2.x/examples/Interactive%20Widgets/Using%20Interact.ipynb
  - http://nbviewer.ipython.org/github/minad/iruby/blob/master/IRuby-Example.ipynb
- mongodb or redis?
- markdown?
- enable "-" todos like Taskpaper?
- sync with Dropbox
- collaboration tools (wiki or OT/sync.js style?) like Google Docs

## Example from Soulver

month: 31 d × 24 hrs
    term: 36 mo heavy utilization
    AWS Reserved Pricing: (CPUs, ECU, Mem GiB, Storage GB)
    SPOT m1.xlarge (4/8/15/4x420): monthly cost is 744 × $0.0521 per month
    m1.large (2/4/7.5/2x420): monthly cost is 744 × $0.034 per hr + ($750 upfront / 744) per mth
    SPOT m1.large (2/4/7.5/2x420): monthly cost is 744 × $0.0261 per month
    m1.medium (1/2/3.75/410): monthly cost is 744 × $0.017 per hr + ($375 upfront / 744) per mth

## Embedded Databases/Spreadsheets

- importable
- can get live/realtime data from json, websockets or google docs
- "*" signifies the "slug" field

```
    ┌---------------------------------------------------------------------------------┐
    |                                 t1 ECU Sizes                                    |
    ├-------------------------------------------------------------------------------┬-┤
    | | A         | B   | C   | D       | E           | F          | G       | H    | |
    | | *Size     | CPU | ECU | Mem GiB | Storage GiB | V Price Hr | Upfront | Type |+|
    |1| m1.xlarge |   4 |   8 |      15 |       4x420 |    $0.0521 |      $0 | SPOT | |
    |2| m1.large  |   2 |   4 |     7.5 |       2x420 |     $0.034 |    $750 | reg  | |
    |3| m1.large  |   2 |   4 |     7.5 |       2x420 |    $0.0261 |      $0 | SPOT | |
    |4| m1.medium |   1 |   2 |    3.75 |         410 |     $0.017 |    $375 | reg  | |
    |+|           |     |     |         |             |            |         |      | |
    └-------------------------------------------------------------------------------┴-┘
```

## Embedded Functions

- python?
- works on data values, numbers, strings
- would need to consider functional vs. OO
- functional might work better on this kind of data

Example function:

┌-------------------------------┐
    |        f1 multiply_list       |
    ├-------------------------------┤
    |1|def multiply_list(v, m):     |
    |2|  for i in v:                |
    |3|    i = i * m                |
    |4|  return v                   |
    |5|                             |
    └-------------------------------┘

## Spreadsheet Query Language

- copied from python + Google Docs
- needs more investigation

Some syntax ideas:

t1.A1:B1
    multiply(t1.F1:F3, 13)
    t1.Size.1
    t1.1.Size
    t1['m1.xlarge']['Size']
    ['ECU Sizes']['m1.xlarge']['Size']
    ECU Sizes m1.xlarge Size
    ECU Sizes|m1.xlarge|Size
    ECU Sizes!m1.xlarge!Size
    Google docs style: "='Sheet number two'!B4"

Can apply filters:

t1.F X month | < $20

## Live output from queries on every line

This is from `t1.F X month | < $20`:

┌-----------------------------------┐
    | t1 ECU Sizes | t1.F X month < $20 |
    |-----------------------------------|
    | | F                               |
    | |                        Price Hr |
    |3|                        $19.4184 |
    |4|                          $13.15 |
    └-----------------------------------┘

## Live output can also result in single values

Output should look more like soulver with the results to the right of every line:

t1.F.1 X month # $38.7624

# Installation & Runtime

> npm install && bower install
    > grunt serve
