There is a cgo file in here that specifies -funroll-loops (fun!). Since
Go 1.9.4, only C compiler flags on a whitelist are allowed, and of course
that flag is not on it.
All the features you expect from a modern grep alternative.
RegEx - perl compatible regular expression syntax (no more escape
hell)
usable defaults - basic options known from grep but with usable
defaults
multiline support - find matches spanning over multiple lines
replace - replace output to reformat it to your needs without
relying on awk/sed
gzip files - search through normal and gzip'ed files in one program
call
multiple patterns - search for multiple patterns in one run
target selection - select or exclude search targets based on file
name, directory name, path and type
handling big data - sift handles big files without problems: files
>50GB, >5,000,000,000 lines and >5,000,000,000 matches successfully
