It sorts games by tags and add eco, opening and variation.
Project description
PgnHelper
An application that can sort games in pgn file and add eco codes, opening and variation names.
It can sort on event, site, date, round, white, black eco, ecot and plycount tags.
There are 2 types of ECO codes that it adds first the ECO based from the first 4 plies and second the ECOT or ECO by transposition after 24 plies. The same can be said for the opening and variation, there are OpeningT and VariationT.

The new ECOT, OpeningT and VariationT are based from the input eco.pgn file. You can get eco.pgn which is based from the eco.pgn from pgn-extract.

usage: pgnhelper.py [-h] [-v] {sort,addeco} ...
positional arguments:
{sort,addeco}
sort Sort the games from the given pgn file based on the given game tags. e.g. python pgnhelper.py sort
mygames.pgn --outpgnfn out.pgn --sort-tag opening --sort-direction hightolow
addeco Add eco and ecot codes, opening and variation names to the input pgn file. The eco, opening etc. are
from the given input file eco.pgn. e.g. python pgnhelper.py addeco --inpgnfn mygames.pgn --inecopgnfn
eco.pgn --outpgnfn out.pgn
optional arguments:
