New fxg for me

previos article about fxg

fxg means find and xargs then grep. It has a insufferable performace, so
I use ag to instead, after forking some tools made by lilydjwg The tool chain is used for finding pattern in files and opening file by vim. I rewrite a simple version of vv.

#!/usr/bin/env python
import sys
from subprocess import call
line_number = int(sys.argv[1])
with open('/tmp/fxg.log') as f:
    for index, line in enumerate(f.readlines()):
        if index == line_number - 1:
            args = line.split(':')
            filename = args[0].strip().split("\t")[1]
            file_line = args[1]
            print filename + ":" + file_line
            call(["vim", filename,  "+" + file_line])

Insert of writing regex pattern to match the complex colored output, I call ag the second time to gen a un-colored output to log file. And I also add a -G for file pattern.

fxg () {
    ag -s -G $1 --column --nogroup --color $2 | nl && ag -s -G $1 --column --nogroup $2 | nl > /tmp/fxg.log
}

Ag on my MacOSX has an unstable sorting result. It makes the twice call of Ag return different order.
So I add sort to this command. -0 or -print0 will take space in filename as a special character.

fxg () {
    ag -s -G $1 --column --nogroup --color -0 $2 | sort | nl && ag -s -G $1 --column --nogroup -0 $2 | sort | nl > /tmp/fxg.log
}
