How to search Ruby files in Windows

[Chris Gehlker]

Sometimes you want to find some particular code snippet and all you
know is that it is in some file in a given directory. For example, if
you are reading the Pickaxe book and you want to actually run some
example code, all you know a priori is that it is somewhere in
ex0001.rb through ex1608.rb. I use a Mac and the wonderful Spotlight
Ruby Importer available at:
<http://www.arcadianvisions.com/>
makes it trivial to find a file containing any given code snippet. I
have a friend who uses Windows and she doesn't know how to achieve
the same functionality. I've tried running RDoc on the directory
containing the Pickaxe code but it quits because it only works on
file that actually compile.

So all this is simply to ask: What is the Windows equivalent to the
Spotlight Ruby Importer.

Wow, that's sort of sexy. Hadn't seen that before.

The Windows Way might be to use the Find command (Windows-F) and enter
content type in "A word or phrase in the file". Bleah.

What I do is use my little "findfile" ruby script (code below) from the
command line. It's sort of like a grep utility that allows you to use
regexps as a filter for file names, and as a content searcher. For
example

C:\Documents and Settings\gavin.kistner\Desktop>findfile rbw?$ "def
\S+awl"
../ReArchive/Archive/dircrawl.rb
def self.crawl ( path, level=0 )

Found 1 file (out of 7510) in 2.765 seconds


C:\WINDOWS\system32>type findfile.rb
require_gem 'usage'
usage = Usage.new "[-d %max_depth] name_regexp [content_regexp]"

class Dir
def self.crawl( path, max_depth=nil, depth=0, &block )
return if max_depth && depth > max_depth
begin
if File.directory?( path )
files = Dir.entries( path ).select{ |f| f[0,1]!='.' }
unless files.empty?
files.collect!{ |file_path|
Dir.crawl( path+'/'+file_path, max_depth, depth+1, &block )
}.flatten!
end
return files
elsif File.file?( path )
yield( path, depth )
end
rescue SystemCallError => the_error
warn "ERROR: #{the_error}"
end
end
end

start_time = Time.new
name_match = Regexp.new( usage.name_regexp, true )
content_match = usage.content_regexp && Regexp.new(
".{0,10}#{usage.content_regexp}.+", true )

file_count = 0
matching_count = 0
Dir.crawl( '.', usage.max_depth ){ |file_path, depth|
if File.split( file_path )[ 1 ] =~ name_match
if content_match
if IO.read( file_path ) =~ content_match
puts file_path," #{$~}"," "
matching_count += 1
end
else
puts file_path
matching_count += 1
end
end
file_count += 1
}
elapsed = Time.new - start_time

puts "Found #{matching_count} file#{matching_count==1?'':'s'} (out of
#{file_count}) in #{elapsed} seconds"

Can you give us the non-RubyURL link, since the service seems to be
down currently?

Although the rubyurl link worked for me just now, here's
what it resolved to:

Thanks Phrogz, I'll pass it on right now.

I use cygwin (www.cygwin.com) and something like:
( mod to your liking, or make different versions for different needs)

cyberhome: /home/rthompso/bin>
$ cat greprb
if [ $# = 1 ]
then
dir=.
echo "dir is $dir"
else if [ $# = 2 ]
then
dir=$2
echo "dir is $dir"
else
echo "Usage: 'basename $0' pattern [path]"
echo "don't forget to quote patterns with spaces"
echo "\n"
exit 1
fi
fi

find $dir -type f -name \*.rb -exec grep -l "$1" {} \; -exec grep -n
"$1" {} \; -exec echo " " \;

Example output ( filepath and line of occurance ):

That's pretty cool too.

Actually, I think Windowsen have a document indexing service hidden
somewhere. Hard to believe it wouldn't do as much as fulltext document
indexing. And it's also probably extensible if you know the proper hand
motions and undocumented API calls. Maybe.

Buggered if I know how to get it to work, and the last time I let the
system index hard drive contents, it hogged the drives to no end. But it
is a hint to Windows hackers that would find this an interesting problem
to solve.

Not a good one. Use Google Desktop, or Yahoo Desktop, or MSN Desktop.

I use the former, when I'm on Windows.
