[Golfing] Filter - Inori - 08-26-2015

Oh boy! More golfing challenges!

You'll be given a bunch of text for your program to process line-by-line, and said text will be full of words and randomly generated non-word characters.

With that text in a separate file, your code needs to go through it one line at a time, sorting out all the random crap and outputting the words, separated by spaces.

Spoiler: InputCode:
[.;'/Hello,';`~world
(*^Oh'.>:$fuck>":}what?>)#happened>:?$%here
{">?Alrighty>:%&then

Spoiler: My solution
Ruby, as usual


129 bytes. I feel like I could've done better, but I got stumped trying to get any smaller.
Code:
File.open(ARGV[0]).each_line{|l|x=[];l.each_char{|c|/[A-z]/.match(c) ? x<<c : x[-1]==" "||x[-1]==nil ? nil : x<<" "};puts x.join}

Spoiler: OutputCode:
Hello world
Oh fuck what happened here
Alrighty then

Spoiler: BIG tip
Regex (or Regexp) is your friend here.

Code:
print'\n'.join(' '.join(`[[' ',c][c.isalpha()]for c in l]`[2::5].split())for l in list(open('w','r')))

Haven't tested it, but I'm pretty confident It works. 102 Bytes.

Not a fan of regex, I'll attempt it without using it in a bit.

EDIT: I used regex. Sorry.

Python, right?

'w' is the file containing the strings, haha Tongue

You have to put the file in the same location as the script. I just tested, seems to work:

Do you guys allow bash?

53

Code:
while read l;do
echo ${l//[^a-zA-Z0-9]/' '}
done < t

file name is t

Output:

Why not use gsub for Ruby?

Code:
IO.foreach('t')do|l|p l.gsub(/[^a-zA-Z0-9]+/,' ')end

I was thinking about gsub, but it gives me spaces before and after the desired string. That's the only reason I needed ||x[-1]==nil.

Oh I did not notice. Try this.

Code:
IO.foreach('t')do|l|p l.gsub(/[^a-zA-Z0-9]+/,' ')[1..-2]end

So that is ~60

[1..-2] will make it so it prints the from index 1 to the second to last index. Confusing shit. For example the string is this
" Hello world \n"
so index one is H and index -2 is d so it will print from H to d.

Code:
import re
for x in open('i'):print' '.join(re.sub('[^a-zA-Z\n]',' ',x).split())

79 bytes

Holy fuck I beat @Shebang.

EDIT: re.sub shit isn't mine btw. I suck at regex. It's a thingy I found on stack overflow that I modified to suit my needs. I can't take credit for it.

What the hell are you doing putting the print on another line? Save your bytes!

Also, in my defense I've never learned Regex Tongue
