Udger Golang
This package reads in memory all the database from Udger and lets you lookup for user agent's metadata. The parsing only relies on the golang standard library regex. Only the Udger Data v3 - Sqlite3 format is supported.
This package is a fork of https://github.com/yoavfeld/udger itself forked from https://github.com/udger/udger.
Tests / Benchmarks
To run tests and benchmarks you need to have the Udger database udgerdb_v3.dat located in this folder.
To run unit tests and run:
go tests ./...
To run tests with benchmarks:
go test -bench=.
