[SOLVED] How to get equal spacing in ssh with javascript console.log

Issue

I'm running javascript with node.js and looking at the console.logs through Putty.

How can I get the terminal in ssh to show me things with the tabs inline? I see two tab spaces but the string following is out of place depending on how long the first string is.

console.log('short'+'\t\t'+'valueA');
console.log('looooooong'+'\t\t'+valueH);

I might get something like this

short        valueA
looooooong        valueH

whereas for readability it would be much nicer to see

short        valueA
looooooong   valueH

Solution

There's a module to handle this scenario, called tab. You could do:

var mod_tab = require('tab');

mod_tab.emitTable({
  'columns': [{
    'align': 'left',
    'width': 12
  }, {
    'align': 'right',
    'width': 10
  }],
  'omitHeader': true,
  'rows': [
    ['short', 'valueA'],
    ['looooooooong', 'valueH']
  ]
});

It has some interesting features, that you could check out by reading the docs.
