================

A parser to parse table style output from shell

## Install

```

npm install table-parser

```

## Usage

We have some kind of log below as `test/ps.log`:

```bash

  PID TTY           TIME CMD

49692 ttys000    0:00.06 login -pfl neekey /bin/bash -c exec -la bash /bin/bash

49693 ttys000    0:00.06 -bash

54195 ttys000    0:00.09 node run

...

56266 ttys005    0:00.06 login -pfl neekey /bin/bash -c exec -la bash /bin/bash

56269 ttys005    0:00.04 -bash

56463 ttys005    0:00.09 node test.js

56464 ttys005    0:00.01 ps -a

```

Use table-parser to parse it into object:

```

var FS = require( 'fs' );

var Parser = require('table-parser');

var linux_ps = './ps.log';

data = FS.readFileSync( linux_ps ).toString();

var parsedData = Parser.parse( data );

console.log( parsedData );

```

Which will output:

```bash

[ { PID: [ '49692' ],

    TTY: [ 'ttys000' ],

    TIME: [ '0:00.06' ],

    CMD:

     [ 'login',

       '-pfl',

       'neekey',

       '/bin/bash',

       '-c',

       'exec',

       '-la',

       'bash',

       '/bin/bash' ] },

  ...

  { PID: [ '56464' ],

    TTY: [ 'ttys005' ],

    TIME: [ '0:00.01' ],

    CMD: [ 'ps', '-a' ] } ]

```

## Double quotation marks

Normally, all the values will be transformed into array using `split( /\s+/ )`, but string wrapped with `"` will be treated as a continuous string. 

For example, the CommandLine below:

```

"C:\Program Files\Internet Explorer\iexplore.exe" --name="Jack Neekey" --sex=male otherargs

```

will be split into:

- `C:\Program Files\Internet Explorer\iexplore.exe` ( `"` will be removed, if `"` is at the beginning )

- `--name="Jack Neekey"`    ( `"` is reserved )

- `--sex=male`

- `otherargs`
