airac: a small Go library for calculating aviation AIRAC cycle dates

Package airac provides calculations on Aeronautical Information Regulation And Control (AIRAC) cycles, i.e. cycle identifiers and effective calendar dates.

Regular, planned Aeronautical Information Publications (AIP) as defined by the International Civil Aviation Organization (ICAO) are published and become effective at fixed dates. This package implements the AIRAC cycle definition as published in the ICAO Aeronautical Information Services Manual (DOC 8126; AN/872; 6th Edition; 2003). Test cases validate documented dates from 1998 until 2020, including the rare case of a 14th cycle in the year 2020.

Wikipedia

Article on AIP / AIRAC cycles: https://en.wikipedia.org/wiki/Aeronautical_Information_Publication

There are wiki macros in that article that do basically the same thing as this library. Though, this library does not trip over the case of 14 cycles per year (e. g. 1998 and 2020).

airac's Issues

go mod tidy is complaining

user@unknown:~/gocode/src/github.com/jwkohnen/airac$ go mod tidy
go: finding github.com/jwkohnen/airac/proto latest
github.com/jwkohnen/airac imports
	github.com/jwkohnen/airac/proto: no matching versions for query "latest"

I see 2 possible workarounds: commit the airac.pb.go file or add a dummy .go file into the proto directory with the content package proto
