# DOT DSL
Write a Domain Specific Language similar to the Graphviz dot language.
A [Domain Specific Language
(DSL)](https://en.wikipedia.org/wiki/Domain-specific_language) is a
small language optimized for a specific domain.
For example the dot language of [Graphviz](http://graphviz.org) 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.
## Running tests
Execute the tests with:
```bash
$ elixir dot_dsl_test.exs
```
### Pending tests
In the test suites, all but the first test have been skipped.
Once you get a test passing, you can unskip the next one by
commenting out the relevant `@tag :pending` with a `#` symbol.
For example:
```elixir
# @tag :pending
test "shouting" do
assert Bob.hey("WATCH OUT!") == "Whoa, chill out!"
end
```
Or, you can enable all the tests by commenting out the
`ExUnit.configure` line in the test suite.
```elixir
# ExUnit.configure exclude: :pending, trace: true
```
For more detailed information about the Elixir track, please
see the [help page](http://exercism.io/languages/elixir).
