Nohrio

nohrio is a python package by David Gowers designed to facilitate OHRRPGCE data manipulation utilities and human inspection of data, by providing:

• numpy.memmap based interface for directly manipulating OHRRPGCE fixed-length-record based data files.
• classes for accessing (some) data where the memmap interface is not appropriate, such as binSize, fixBits and Script
• a human readable and editable YAML serialization of all records, upon which standard tools like ‘grep’ and ‘diff’ are applicable
• sane, readily updateable binary serialization of the insane-in-spots OHRRPGCE formats

nohrio is available at:

• https://github.com/ohrrpgce/nohrio
• https://bitbucket.org/rbv/nohrio

There are two branches:

• master is the branch used by existing utilities such as rpgbatch and tabulate.py. It adds a number of convenience classes and is semi-maintained (though lump definitions are typically a bit out of date)
• nohrio2 is David's rewrite of nohrio which abandons the pure numpy.memmap-based interface in favour of class-based abstractions over data. This branch is very stale.

Aside from the fact that the nohrio2 branch targets a very old OHRRPGCE version, it's not clear whether it was ever in a usable state. Eventually we would like to port all the improvements from master over to nohrio2 and convert rpgbatch to use that branch, but currently noone has time for it.
