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

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.

func Parse(input string, delim string) string

Use ParseF to override default options.

func ParseF(input string, delim string, options Options) string

For use with ParseF - where options is a golumn.Options struct containing a subset of the following

ColumnSpacer string - The characters used to pad columns, default is \t.
NewLine string - New line character, default is \n.
ColumnWidth int - Sets colums to be a fixed width.
MaxColumnWidth int - Constrains column widths. Overidden if a valid ColumnWidth option is given.
Truncate bool - Truncates any cells that overflow the ColumnWidth or MaxColumnWidth.
