This program takes all the Machine class methods and prints its methods in
|
|
markdown-style. These can then be included in the NixOS test driver
|
|
markdown style, assuming the docstrings themselves are also in markdown.
|
|
|
|
These are included in the test driver documentation in the NixOS manual.
|
|
See https://nixos.org/manual/nixos/stable/#ssec-machine-objects
|
|
|
|
The python input looks like this:
|
|
|
|
```py
|
|
...
|
|
|
|
class Machine(...):
|
|
...
|
|
|
|
def some_function(self, param1, param2):
|
|
""
|
|
documentation string of some_function.
|
|
foo bar baz.
|
|
""
|
|
...
|
|
```
|
|
|
|
Output will be:
|
|
|
|
```markdown
|
|
...
|
|
|
|
some_function(param1, param2)
|
|
|
|
: documentation string of some_function.
|
|
foo bar baz.
|
|
|
|
...
|
|
```
