Functions:

epygram.formats.guess(filename)

Returns the name of the format of the resource located at a given filename, if succeeded.

epygram.formats.resource(filename, openmode, fmt=None, **kwargs)

Returns an instance of Resource of the requested fmt format, located at the given filename, open with the given openmode.

Parameters:

• filename – name (path) of the file to open

• openmode – opening mode (‘r’, ‘a’, ‘w’)

• fmt – format of the resource; with openmode ‘r’ or ‘a’, fmt is optional and can be guessed from the existing resource

Other kwargs are passed to the resource constructor.

epygram.formats.available_format(fmt)

Check availability of low-level libraries for activating format.
