An Elixir app which generates text-based tables for display

Currently supports output:

• in customisable ASCII format.
• with your own renderer.

####Features

• A one-liner for those that just want to render ASCII tables with sane defaults.
• Support for table titles & alignable headers.
• Support for column & cell level alignment (center, left, right).
• Automatic cell padding but also the option to set padding per column¹.
• Frame the table with various vertical & horizonal styles¹.
• Style the table how you wish with custom separators¹.
• Works well with the Agent module to allow for easy sharing of state.
• Clients can supply their own rendering modules and still take advantage of the table manipulation API.

####Stability

This software is pre-v1 and therefore the public API may change; any breaking changes will be clearly denoted in the CHANGELOG. After v1, the API will be stable.

####Documenation

See the quick start below or check out the full API docs at HexDocs.

Installation

The package is available on Hex, therefore:

Addtable_rex to your list of dependencies in mix.exs:

def deps do
  [{:table_rex, "~> 0.2.0"}]
end

Then starttable_rex by adding it to application/0 in mix.exs:

def application do
  [applications: [:logger, :table_rex]]
end

##Quick Start

Use the TableRex.quick_render and TableRex.quick_render! functions; for those that just want a table quickly.

Given this data:

title = "Drum & Bass Releases"
header = ["Artist", "Track", "Label", "Year"]
rows = [
  ["Konflict", "Cyanide", "Renegade Hardware", 1999],
  ["Marcus Intalex", "Temperance", "Soul:r", 2004],
  ["Kryptic Minds", "The Forgotten", "Defcom Records", 2007]
]

##Run the tests

We have an extensive test suite which helps showcase project usage. For example: the quick render functions, table manipulation API or the text renderer module.

To run the test suite, from the project directory, do:

mix test
