Looking for an easy way to remove all of my TODO: Comments throughout an entire directory of scripts.
If I have:
/*
TODO: Some text here
Some more Here
Some more Here
*/
I want to delete the /* Everything in Between and */ Not a huge deal, just wondering for decreasing file sizes
分享 Here is something to start with:
$file = 'somefile.php';
$f = fopen($file,'r');
$temp = dirname($file).'/temp.php';
print_r($temp);
$t = fopen($temp, 'w');
$mode = 'write';
$buffer = [];
while($line=fgets($f)){
print_r($mode."
");
switch($mode){
case 'write':
if(preg_match('/^\s*\/\\*/', $line)){
$buffer[] = $line;
$mode = 'comment';
}else{
fputs($t,$line);
}
break;
case 'comment':
if(preg_match('/^\s*\\**\s*@TODO/i', $line)){
$buffer = [];
$mode = 'skip';
}else if(preg_match('/^\s*\\*\//', $line)){
fwrite($t,implode("", $buffer));
$buffer = [];
fputs($t,$line);
$mode = 'write';
}else{
$buffer[] = $line;
}
break;
case 'skip':
if(preg_match('/^\s*\\*\//', $line)){
$mode = 'write';
}
break;
}
}
/*
fclose($t);
fclose($f);
rename($temp, $file);
*/
I tested it against this file
<?php
$var= "foo";
/*
@todo hello
some other shuff
*/
/**
*
* @author Me
*
*/
class someclass{
}
This was the stuff in temp.php
<?php
$var= "foo";
/**
*
* @author Me
*
*/
class someclass{
}
hope it helps. I would probably back up your files before attempting this.
UPDATE
Had to fix a couple minor things so it would skip comments without @todo. The rest you can probably work out fairly easily.
The regex is only there to account for spaces or comments that are like this
/*
* @todo
*/
This \\* becomes \* for the regex engine that then becomes a literal *.
So this one \s*\/\\*
\s* - none or more spaces\/ - the / literally\\* - the * literallyOr in English the /* open comment tag.
I mention this because the regex is tricky, but you probably have spaces and other stuff in there, probably every @todo isn't the very first thing on the line.
Doing it like this, you get to handle each line on it's own, it simplifies things and more importantly increases the matching accuracy.
