Hello,
I try a little function, but I encountered a problem. I need do determine, for each code, tab length…
<?php
$var = ' // this is a test
with a second line
//and a third line';
$regex = '/(^\t|^:space:+)/';
$count = array();
$var2 = explode( "\n", $var );
$mini = PHP_INT_MAX;
foreach( $var2 as $v ) {
if ( ! preg_match( $regex, $v, $match ) ) {
$mini = PHP_INT_MAX;
break;
} elseif ( strlen( $match[0] ) < $mini ) {
$mini = strlen( $match[0] ); //how many spaces for a tab ?
}
}
if ( $mini != PHP_INT_MAX ) {
$regex2 = '/(^\t|^:space:{' . $mini . '})/';
$regex4 = '/\n\t|\n:space:{' . $mini . '}/';
$var = preg_replace( $regex2, "", $var );
$var = preg_replace( $regex4, "\n", $var );
}
// $var is now indented correctly
Yes, it is not simple 🙂
A simple solution is maybe to remove first white char (space or \t) of every lines until at least one line first char is not a white char.
For example:
__a
____b
______c
becomes in the first iteration:
_a
___b
_____c
and finally:
a
__b
____c

Hello Willy,
As i am not confident with regexp, so i have tried with a simple class to handle code indentation.
The result is here, if you need:
