Sphinx-needs-data-explorer is a Sphinx extension to visualize Sphinx-Needs data

Sphinx Needs Data Explorer

The sphinx_needs_data_explorer is a web application written in HTML, CSS, and JavaScript, provided as a Sphinx extension. It enhances the interactivity of your Sphinx-generated documentation by enabling you to explore needs.json sphinx-needs-data generated by the Sphinx-Needs extension.

Goals and Realization

Features

Three Sphinx-Needs Data View Perspectives

Network-View

In Network-View-Perspective you can see how sphinx-needs data are interconnected in data networks.

You can choose which data context to see - incoming connections from in-neighbours - outgoing connections from out-neighbours - incoming and outgoing connections

You can choose network layout - hierarchical bottom-up - hierarchical right-to-left - hierarchical with repulsion

Table-View

In Table-View-Perspective you can see sphinx-needs data in table. You can select which columns should be visible and which hidden.

File-View

In File-View-Perspective, you can see a list of files in which Sphinx-needs data were found.

Powerfull Interactive Data Filtering

You can predefine filtering expressions during documentation generation or interactively while browsing documentation, and apply the data filtering across all three view perspectives.

You can use attribute lookup table while writing your filters.

Exploring In-Neighbours, Out-Neighbours or both

Visualizing Constraint Violations in Network Transitions

Controlling Neighborhood Depth in Network Visualization

Switching between Perspective Views and Documentation

Interaction

Installation

You can install sphinx-needs-data-explorer with pip

pip install sphinx-needs-data-explorer

Alternatively (Linux)

git clone https://github.com/mi-parkes/sphinx-needs-data-explorer.git
cd sphinx-needs-data-explorer

poetry install
poetry build
poetry run task doc

# you can then install the package in your virtual environment
pip install dist/sphinx_needs_data_explorer*.whl

Activation

In your conf.py configuration file, add sphinx_needs_data_explorer to your extensions list. And, please, make sure that sphinx_needs extension is configured to generate needs.json file in the root of your documentation E.g.:

extensions = [
  ...
  'sphinx_needs_data_explorer'
  ...
]
...
needs_build_json = True

or you can include it only if the extension is available in your virtual environment:

...
try:
    import sphinx_needs_data_explorer
    extensions.add('sphinx_needs_data_explorer')
except ImportError:
    pass
...
needs_build_json = True

If your project uses sphinx_book_theme, sphinx_needs_data_explorer supports full integration in your documentation by adding E header button accesible from any documentation page.

Otherwise, you can create hyperlink to sphinx_needs_data_explorer by adding the following role in your .rst file(s)

:sphinx_needs_data_explorer:`Sphinx Needs Data Explorer Test`

Configuration

If defined, the following parameters are used for configuration:

• needs_extra_options - the parameter defines extra sphinx-needs options

• needs_extra_links - the parameter defines the type links to use when extracting sphinx-needs linkage

• needs_types - the parameter defines sphinx-needs types and their attributes like node colors

You can predefine filtering expressions to populate the filter drop-down list:

sphinx_needs_data_explorer_config = {
    "filters":[
        "status=='open'",
        "['15','16'] in id",
        "title ~ /r.*[0-9]+5'$/i",
        "type != 'req' && incoming==[]",
        "type=='spec' && outgoing!=[] && title ~ /5'$/"
    ]
}

sphinx_needs_data_explorer Help lists all attributes found in your project that can be used for data filtering.

Visualizing Constraint Violations in Network Transitions:

sphinx_needs_data_explorer_config = {
    "valid-linkage-color":"Black",
    "invalid-linkage-color":"OrangeRed",
    "valid-linkage":{
        'need': {
            'need':'refinement'
        },
        'feat': {
            'feat':'refinement',
            'need':'links'
        },
        ...
    }
