[PATCH v5 01/11] ref-filter: introduce 'ref_formatting_state'

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Introduce 'ref_formatting' structure to hold values of pseudo atoms
which help only in formatting. This will eventually be used by atoms
like `color` and the `padright` atom which will be introduced in a
later patch.
