## How it works?

- The [index.html](index.html#L82-L95) page sends XHR requests containing your Graphviz input to the [dot-to-ascii.php](dot-to-ascii.php) script

- The [dot-to-ascii.php](dot-to-ascii.php#L8) script runs the [Graph::Easy](https://metacpan.org/pod/Graph::Easy) command line tool to produce a text diagram from the provided Graphviz input

- The result is returned back to [index.html](index.html#L82-L95) where it is displayed in a `
` tag


## API

Dot-to-ascii can be easily used in your code by performing https requests to the api.

### Python

```python

import requests

def dot_to_ascii(dot: str, fancy: bool = True):

    url = 'https://dot-to-ascii.ggerganov.com/dot-to-ascii.php'

    boxart = 0

    # use nice box drawing char instead of + , | , -

    if fancy:

        boxart = 1

    params = {

        'boxart': boxart,

        'src': dot,

    }

    response = requests.get(url, params=params).text

    if response == '':

        raise SyntaxError('DOT string is not formatted correctly')

    return response

```

``` python

graph_dot = '''

    graph {

        rankdir=LR

        0 -- {1 2}

        1 -- {2}

        2 -- {0 1 3}

        3

    }

'''

graph_ascii = dot_to_ascii(graph_dot)

print(graph_ascii)

```

```

```

## Run locally with docker

This uses the minimal Dockerfile with the default apache config etc. Not

suitable for production use.

``` bash

$ docker build -t dot-to-ascii .

$ docker run --rm -d --name dot-to-ascii -p 8080:80 dot-to-ascii

$ # open localhost:8080 in your browser

```
