IPython.utils.PyColorize:_exec_pygments_style_module

Extended Summary

Returns None if pygments is not laid out as expected, leaving it to the caller to fall back to pygments.styles.get_style_by_name.

The module is executed in isolation and deliberately not registered in sys.modules: registering a submodule of a package that is not itself imported breaks later import pygments.styles.<module> statements, and keeping pygments.styles unimported is the entire point. Style modules are pure data, so executing one twice is harmless, and nothing but the styles dict escapes this function.
