# fansi_text

A Python module for formatting text with ANSI escape codes.

## Installation

```
pip install fansi_text
```

## Usage

```python
from fansi_text import Red

print(Red("Red text"))
```

```python
from fansi_text import RGBColor

print(RGBColor("RGB Text", 200, 130, 60))
```

You can also form complex combinations of overlapping effects.
```python
import fansi_text as ft

print(
    ft.Bold("Bold, " +
         ft.Green("green and bold. ")) + 
    "Then normal text. Then " +
    ft.Underline(ft.Overline("under and over lined. ")) +
    "Next " + 
    ft.Italic("italics. Add " + 
           ft.Yellow("yellow " + 
                  ft.Bold("and bold too! ") +
                  "Then back to yellow and italics, ") + 
           "then just italics, ") + 
    "and finally back to normal."
)
```
A demo_all method is provided to allow for testing all supported colours and effects in your terminal.
```python
import fansi_text as ft
ft.demo_all()
```

The full list of colours and effects are shown below (notes per [Wikipedia](https://en.wikipedia.org/wiki/ANSI_escape_code#Select_Graphic_Rendition_parameters)).
Note that support for each code varies between terminals.
