sphinx.ext.viewcode – Add links to highlighted source code

Autor del módulo: Georg Brandl

Nuevo en la versión 1.0.

This extension looks at your Python object descriptions (.. class::, .. function:: etc.) and tries to find the source files where the objects are contained. When found, a separate HTML page will be output for each module with a highlighted version of the source code, and a link will be added to all object descriptions that leads to the source code of the described object. A link back from the source to the description will also be inserted.

Advertencia

Basically, viewcode extension will import the modules being linked to. If any modules have side effects on import, these will be executed when sphinx-build is run.

If you document scripts (as opposed to library modules), make sure their main routine is protected by a if __name__ == '__main__' condition.

In addition, if you don’t want to import the modules by viewcode, you can tell the location of the location of source code to viewcode using the viewcode-find-source event.

If viewcode_follow_imported_members is enabled, you will also need to resolve imported attributes using the viewcode-follow-imported event.

This extension works only on HTML related builders like html, applehelp, devhelp, htmlhelp, qthelp and so on except singlehtml. By default epub builder doesn’t support this extension (see viewcode_enable_epub).

Configuration

viewcode_follow_imported_members

If this is True, viewcode extension will emit viewcode-follow-imported event to resolve the name of the module by other extensions. The default is True.

Nuevo en la versión 1.3.

Distinto en la versión 1.8: Renamed from viewcode_import to viewcode_follow_imported_members.

viewcode_enable_epub

If this is True, viewcode extension is also enabled even if you use epub builders. This extension generates pages outside toctree, but this is not preferred as epub format.

Until 1.4.x, this extension is always enabled. If you want to generate epub as same as 1.4.x, you should set True, but epub format checker’s score becomes worse.

The default is False.

Nuevo en la versión 1.5.

Advertencia

Not all epub readers support pages generated by viewcode extension. These readers ignore links to pages are not under toctree.

Some reader’s rendering result are corrupted and epubcheck’s score becomes worse even if the reader supports.

viewcode-find-source(app, modname)

Parameters:
  • app – The Sphinx application object.
  • modname – The name of the module to find source code for.
viewcode-follow-imported(app, modname, attribute)

Nuevo en la versión 1.8.

Find the name of the original module for an attribute.

Parameters:
  • app – The Sphinx application object.
  • modname – The name of the module that the attribute belongs to.
