This is a fork of github.com/vjeantet/grok with improved concurrency. This fork is not 100% API compatible but the underlying implementation is (mostly) the same.
The main intention of this fork is to get rid of all the mutexes in this library to make it scale properly when using multiple go routines. Also as grok is an extension of the regexp package the function scheme of this library should be closer to golang's regexp package.
- All patterns have to be known at creation time
- No storage of known grok expressions (has to be done be the user, similar to the go regexp package)
- No Mutexes used anymore (this library now scales as it should)
- No Graphsort required anymore to resolve dependencies
- All known patterns text files have been converted to go maps
- Structured code to make it easier to maintain
- Added tgo.ttesting dependencies for easier to write unittests
- Fixed type hint case sensitivity and added string type
- Added []byte based functions
