# PrettyTable

*PrettyTable* is a simple shell implementation to draw nice looking ascii
tables with auto sizing columns to the screen.

## Prerequisites

The `column` utillity as well as `sed` are needed for this script to work.

The implementation has been tested using *bash* as well as *zsh*.

## Installation

Options

* Copy and paste the code in your script
* Download it and chmod +x the script then save it somewhere on your PATH and source it
* If you have [basher](https://github.com/basherpm/basher) then `basher install jakobwesthoff/prettytable.sh`

## Usage

You may either source the `prettytable.sh` file or use it as an executable.
Both works just fine.
See [Installation](#installation) for install options.

Multiline table data is simply piped into `prettytable` for formating, while
the number of columns needs to be specified. Columns need to be delimited using
a `\t` (Tab) character.

Optionally a color may be specified as second argument to `prettytable`. This
color will be used to to color the header text. Available colors:

- blue
- green
- cyan
- red
- purple
- yellow
- gray
- light_blue
- light_green
- light_cyan
- light_red
- light_purple
- light_yellow
- light_gray

## Example

```bash
{
 printf 'PID\tUSER\tAPPNAME\n';
 printf '%s\t%s\t%s\n' "1" "john" "foo bar";
 printf '%s\t%s\t%s\n' "12345678" "someone_with_a_long_name" "blub blib blab bam boom";
} | prettytable 3
```

```
┌────────┬────────────────────────┬───────────────────────┐
│PID     │USER                    │APPNAME                │
├────────┼────────────────────────┼───────────────────────┤
│1       │john                    │foo bar                │
│12345678│someone_with_a_long_name│blub blib blab bam boom│
└────────┴────────────────────────┴───────────────────────┘
```

**NOTE:** The spacing between lines is a result of Githubs formatting and should not occure in your terminal.
