grep

README

go-grep

go-grep is a simple library for replacing grep functionality written in pure go

Limitations

• This implementation can't read lines with more than 65536 symbols (this will provide error bufio.Scanner: token too long) because of perfomance degrading. Read more about MaxScanTokenSize in bufio doc
• Also this search implementation will check, if the first line of file can be UTF encoded and stop func, if it can't. See tools doc
