golumn

Format delimited data into columns. Similar to the unix shell program column.

Example

Some CSV file:

Date,Type,Description,Amount
30/10/2013,DEB,SUPERMARKET 29833,5.15
29/10/2013,DEB,AMAZON MKPLACE,5.63

Parse the file:

var result = golumn.parse(string(data), ",", golumn.Options{
	MaxColumnWidth: 5,
	Truncate:       true,
})
print(result)

Prints the following:

Date 	Type	Descr	Amoun
 30/1	DEB 	SUPER	5.15 
 29/1	DEB 	AMAZO	5.63 

Usage

Download and compile the source with go get github.com/st3redstripe/golumn. Then import as usual.

import (
	"github.com/st3redstripe/golumn"
)

Call Parse passing in an input string and a delimiter.
