scrapy spiderdocs

Docstring syntax

Use ; to create sections. For example:

; Section 1

Some text ...

; Section 2

Some text ...

Use ; end to close a section:

This text will not be added to the documentation.

; Section 1

Some text ...

; end

And this text also will be skipped.

Section processors

An example:

SPIDERDOCS_SECTION_PROCESSORS = {
    'output': lambda name, content: '### {name}\n\n```json\n{content}\n```'.format(name=name, content=content)
}

; Output

{
    "attr": "value"
}

will be translated into:

### Output

```json
{
    "attr": "value"
}
```

Scrapy settings

SPIDERDOCS_LOCATIONS: {<module>: <destination>}, default: {}.

SPIDERDOCS_SECTION_PROCESSORS: {<section_name>: <function(name, content) -> str>}, default: {}.

See usage examples above.
