TableParser ![Build Status](https://travis-ci.org/neekey/table-parser)
================

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`
