Installation

If you have a Golang environment setup, you can simply run:

$ go get -u github.com/drgarcia1986/sif/cmd/sif

Or get binaries on releases

For windows users: Colors works only in PowerShell

Example

Run against repo dir:

$ sif better
_tests/golang.txt
9: A little copying is better than a little dependency.
14: Clear is better than clever.

_tests/python.txt
3: Beautiful is better than ugly.
4: Explicit is better than implicit.
5: Simple is better than complex.
6: Complex is better than complicated.
7: Flat is better than nested.
8: Sparse is better than dense.
17: Now is better than never.
18: Although never is often better than *right* now.

sif_test.go
14:             {"python.txt", "better", []int{3, 4, 5, 6, 7, 8, 17, 18}},

Same search with ack, grep and sif, time comparison:

$ time ack better
...
        0.11 real         0.07 user         0.01 sys

$ time grep better -rn *
...
        0.04 real         0.03 user         0.00 sys

$ time sif better
...
        0.01 real         0.00 user         0.00 sys
