How it works?
- The index.html page sends XHR requests containing your Graphviz input to the dot-to-ascii.php script
- The dot-to-ascii.php script runs the Graph::Easy command line tool to produce a text diagram from the provided Graphviz input
- The result is returned back to index.html where it is displayed in a
<pre>tag
API
Dot-to-ascii can be easily used in your code by performing https requests to the api.
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 responsegraph_dot = '''
graph {
rankdir=LR
0 -- {1 2}
1 -- {2}
2 -- {0 1 3}
3
}
'''
graph_ascii = dot_to_ascii(graph_dot)
