Thanks for writing grin, I really like it.

About ack: Its defaults suck. It skips files whose types it doesn’t understand. I’m sure you can reconfigure this, but why worry about re-configuring it correctly on every machine I use, when I can just “easy_install grin” and have it work sanely by default?

Also, a small feature request: grep’s -w option. I think you could basically just tack \b onto the beginning and end of the specified regex and it’d work like -w. It’s an option I find really useful

raja: I had some Python 2.5 syntax in there. This is fixed in SVN and will be pushed as 1.1.1 next week (I’m waiting for more bug reports). In the meantime, ‘easy_install -U “grin==dev”‘ or grab it from SVN at the URL given above.

William: How do I exclude more than one directory name? Like both “build” and “.svn”? As far as I can tell, the glob syntax used there does not allow {.svn,build}.

@rkern So let’s say you have a handy dandy project and you want to see which python files you’ve imported datetime. It has several directories deep and it’s svn controlled. You don’t want to match anything in the .svn directories.

grep -R "import datetime" *.py --exclude=*.svn* --color

Hi,
Tried to use after installing via “easy_install grin”.
I am getting following error.

On ack: yup, I used to use ack for this purpose. I got used to -C context lines, though, and at the time I wrote grin, at least, this feature was unimplemented. Being a Python programmer, I thought it would be more fun to write a new tool instead of hacking my way through Perl. The context handling code is not the most straightforward, and I shudder to think about what I would have to do in Perl to get it right.

Uwe: typo in grin.py. I updated the version in setup.py but not in the file itself.

William: I don’t see where grep skips the directories I want to skip. Variations on “–exclude=.svn” certainly don’t seem to accomplish it. Can you give me an example?

I’m sure it was fun to write, but a few lines worth of shell scripting, to stitch find + grep together, would give you the same thing. In fact, I already did that, so here you go, just in case:

$ cat ~/bin/findgrep
#!/bin/bash FILETYPE="*.php" MODE="match" GREPCOLOR="--color=auto" OPTS="Ei"


print_usage()

{

    printf "Usage: %s: [OPTIONS] pattern\n" $(basename $0) >&2

		echo

		echo "-f PATTERN Search in files with filename = PATTERN (default to $FILETYPE)"

		echo "-l print only names of files containing matches"

		echo "-c use markers to highlight the matching strings (default)"

		echo "-C do NOT highlight matching strings"

		echo "-i Run grep pattern case-insensitive (default)"

		echo "-I Run grep pattern case-sensitive"

		exit 2

}
while getopts 'f:lCciI' OPTION

do

    case $OPTION in

        f) FILETYPE="*.$OPTARG"

        ;;

				l) MODE="filename"

				;;

				c)

				;;

				C) GREPCOLOR=""

				;;

				i)

				;;

				I)

				OPTS="E"

				;;

				?) print_usage

        ;;

    esac

done
shift $(($OPTIND - 1))

if [ $# -ne 1 ]

then

	print_usage

fi
case $MODE in

	match)

	OPTS="nH$OPTS"

	;;

	filename)

	OPTS="lH$OPTS"

	;;

	?)

	print_usage

	;;

esac

find . -type f -name "$FILETYPE" -print0 | xargs -0 grep -$OPTS $GREPCOLOR "$1"

grep does the same thing.
ack does the same thing.

Windows search does the same thing. Just install Vista and you get search out-of-the-box!

Its open source, too. If you have a hex editor.

But some of us wanted an extensible python solution.

Grin is Great.

I’ve had to write this sort of thing in both perl and python. (and even java).

Reading man pages for find, grep, and xargs got old pretty fast.

and don’t get me started on windows find.

I use ack, sounds like grin is pretty similar:
