[SOLVED] replacing space indents with tab indents on new lines

[ultrus]

Hello,

I have php documents that use spaces to indent the code, and am planning on using Dreamweaver's find and replace tool with regular expressions to replace the spaces with tabs. How would I find \n following any number of spaces with \n and number of tabs? I don't want to replace all spaces in the document with tabs of course. (If the answer is in php script, that's fine with me)

 

Thanks for the assist!

<pre>
<?php
### Space = #32; Tab = #9.

### How many spaces is a tab?
$tab = 8;

$data = <<<DATA
  2
    4
      6
        8
          10
            12
              14
                16
DATA;

echo preg_replace('/[ \t]/', 'X', $data), '<br>';
print_r(count_chars($data, 1));

echo '<hr>';
$data = preg_replace('/^([ ]+)/me', 'str_repeat("\t", strlen("$1") / $tab)', $data);

echo preg_replace('/[ \t]/', 'X', $data), '<br>';
print_r(count_chars($data, 1));
?>
</pre>

In Dreamweaver, from the top menu, select Edit > Preferences...

In the left category column, scroll down till you see 'code format', click on it.. in the right hand panel, you should see at the top an indent with a checkmark, followed by a number field and a dropdown menu (the default will most likely be 2 in the field and the dropdown set to spaces).. set the field to 1, and set the dropdown to tabs. Click 'OK'.

 

Finally, in the top menu, select Commands > Apply Source Formatting.

 

Done. 

 

Cheers,

nice! Both of those work. I actually did a folder-wide search and replace of double space to dingle tab, since I never used a double space anywhere except for indenting. Now everything is tabbed out. Thanks!
