Dot Dsl

Write a Domain Specific Language similar to the Graphviz dot language.

A Domain Specific Language (DSL) is a small language optimized for a specific domain.

For example the dot language of Graphviz allows you to write a textual description of a graph which is then transformed into a picture by one of the graphviz tools (such as dot). A simple graph looks like this:

graph {
    graph [bgcolor="yellow"]
    a [color="red"]
    b [color="blue"]
    a -- b [color="green"]

Putting this in a file example.dot and running dot example.dot -T png -o example.png creates an image example.png with red and blue circle connected by a green line on a yellow background.

Create a DSL similar to the dot language.

Description of DSL

A graph, in this DSL, is an object of type Graph, taking a list of one or more

described as tuples.

The implementations of Node and Edge provided in dot_dsl.py.

Observe the test cases in dot_dsl_test.py to understand the DSL's design.

Submitting Exercises

Note that, when trying to submit an exercise, make sure the solution is in the exercism/python/<exerciseName> directory.

For example, if you're submitting bob.py for the Bob exercise, the submit command would be something like exercism submit <path_to_exercism_dir>/python/bob/bob.py.

For more detailed information about running tests, code style and linting, please see the help page.

Submitting Incomplete Solutions

It's possible to submit an incomplete solution so you can see how others have completed the exercise.
