year
Theyear filter takes a range as its argument:
year 2000
year 2001 2005
It matches a game whose date field's year is within the year.
It can be specified as a CQL parameter or in the body of the CQL file.
A year filter can be counted in which case it counts the year
of the game, if that year lies within the range.
For example, to sort games by year, use:
cql(input i.pgn)
sort year 2000 2017
The year filter can also be specified on the command line using --year.
