Explicitly splitting long lines in TextMate

Not really a problem so let's write a simple command for this. And here is the result. I don't know if it works in all cases, but I tested it for situations where nothing is selected or whole lines are selected and it seems to work there.

Warning: Don't try this command when you don't have full lines selected. This command wasn't built for this and I haven't yet found a way to check what kind of stuff got selected :) And don't try it on program source code ;-)

import os,sys
   from sys import stdout,stdin

def split_line(line,max_len,tab_size):
       if len(line) <= max_len:
           return [line,]

prefix = &apos;&apos;
prefix_length = 0
if line[0] in (&apos; &apos;,&quot;\t&quot;):
    for c in line:
        if c not in (&apos; &apos;,&quot;\t&quot;):
            break
        else:
            prefix += c
            if c == &apos;\t&apos;:
                prefix_length+=tab_size

lines = []
current_line = []
line_no = 0
words = line.split(&quot; &quot;)
chars = prefix_length
if len(words)==1:
    return [line,]
while len(words) &gt; 0:
    if (chars+len(words[0])) &lt;= max_len:
        word = words.pop(0)
        current_line.append(word)
        chars += len(word)+1
    else:
        if line_no &gt; 0:
            lines.append(&quot;%s%s&quot;%(prefix,&quot; &quot;.join(current_line)))
        else:
            lines.append(&quot; &quot;.join(current_line))
        current_line = []
        line_no+=1
        chars = prefix_length
if len(current_line) &gt; 0:
    if line_no &gt; 0:
        lines.append(&quot;%s%s&quot;%(prefix,&quot; &quot;.join(current_line)))
    else:
        lines.append(&quot; &quot;.join(current_line))
return lines
if name == 'main':
       max_len = int(os.getenv('TM_WRAP_LENGTH',78))
       tab_size = int(os.getenv('TM_TAB_SIZE',4))
       for line in stdin:
           stdout.write("n".join(split_line(line,max_len,tab_size)))

And here's the configuration for this command. I simply put it into a dummy bundle handling all my private extensions to the "Text" bundle ... well, actually this is the first extensions ;-)

Warning: The usual stuff. Use this on your own risk etc.

I hope this might be useful for some of you :-)
