PrettyTable

Format arrays into ASCII tables.

Includes a command line tool pretty_table that reads text input and outputs a pretty table.

Gem Usage

require 'pretty_table'

headers = ['column 1', 'column 2']
rows = [
  [4_294_967_295, 'string'],
  [true, nil],
]

puts PrettyTable.pretty_table(headers, rows)
puts PrettyTable.pretty_table(headers, rows, justify: :left)

Output:

+------------+----------+
|   column 1 | column 2 |
+------------+----------+
| 4294967295 |   string |
|       true |          |
+------------+----------+
+------------+----------+
| column 1   | column 2 |
+------------+----------+
| 4294967295 | string   |
| true       |          |
+------------+----------+

Tool Usage

The command line tool accepts a field separator. It recognizes a single \t as tab, and a single \xHH as a hex specified character.

$ pretty_table -F ,
column 1,column 2
4_294_967_295,string
true,nil
