NAME
search

SYNOPSIS
search Directory re re* [options]+

URIS
http://codeforpeople.com/lib/ruby/
http://rubyforge.org/projects/codeforpeople/

INSTALL
gem install search

DESCRIPTION
search is a combination of find and grep. it recursively traverses a
directory and searches all files for one or more regular expressions,
printing each file containing matches on stdout. by default it
ignores
repo directories like .cvs|.svn|.rcs

PARAMETERS
Directory (1 -> Directory)
re (-2 -> re)
--Filter=Filter, -F (0 ~> list_of_string(Filter=.*))
limit searchs to files matching these regular expressions. may be
given more than once
--All=All, -A (0 ~> All)
*all* Filters must match to be considered a success. default
is that
*any* Filter pattern matching is considered a success
--Ignore=Ignore, -I (0 ~> list_of_string(Ignore=.svn,.cvs,.rcs))
ignore any file matching this list of patterns default
(.svn|.cvs|.rcs)
--Sensitive, -S
conisder all Filters case sensitive. default is case insensitive
--file=file, -f (0 ~> file)
load a file full of patterns, one per line
--sensitive, -s
conisder all patterns case sensitive. default case insensitive
--any, -a
*any* pattern match is considered success. default is that *all*
patterns must match
--verbose, -v
print every match with lineno information
--help, -h


enjoy.

Nice. Playing with it now.

Ps. Your gemspec needs a dependency on main.

yeah i blogged that a while back

http://drawohara.com/post/19092746

bil kleb forwarded it my way. curiously, it'd just written search a
few days before. of course ack is more fully featured - but i
figured i'd better release since ack is in perl and ruby outght to be
represent'n ;-)

NP. I really like this package, BTW.

A problem I just ran into is dot-files (e.g., .tesfile). It looks like
the glob pattern (constructued on line 115) is the problem. In a
directory with .testfile, I get this output:

$ ruby -w 'p Dir["./**/**"]'
[]

$ ruby -e 'p Dir["./.*"]'
["..", ".testfile", "."]

But adding a dot to the double star doesn't work correctly (i.e.,
"./.**/**" get treated as "./../*", doh). I'm not sure there's any
easy way to do it with Dir#glob.

Jordan

Not sure what the difference in performance is with Find#fidn vs.
Dir#glob, but as a drop-in replacement...

Testing on a few different directories and filter patterns, the
Find#find version (w/ filters.match(File.basename(entry))) appears to
be about the same a the Dir#glob version for speed (about two tenths
of a second slower for a directory with 2109 files and a filter
pattern of ".*").

i'll incorporate something like you suggest and re-release. thanks

funny. for me it has been rails that's caused the change: too dang
many files scattered all over the place ;-)

Also http://www.incava.org/projects/glark/, which is Ruby.

And of course also GNU grep, e.g.
grep -r --include=*.c PATTERN DIR

that's kind of interesting - why not simply

search . blah -F /.

though?

this should work unless you happen to have dot-directories too. if so
you can use

search . blah -F '.[^/]+$'

which would filter only dot-files though. i like the filter being
able to filter certain directories too. i could add an option to
alter it's behavior to only match basenames, or add a new option.

thoughts?

Cause I'm not smart, hehe. That works fine.

I don't think you need change anything since there will always be at
least one "/" (and it's just as easy to affix the pattern with / as
type an extra switch). My brain sometimes malfunctions.
