Coding style is key to making sure your programs are maintainable. What's more, it can reduce the errors in your code.
March, 2005: Coding for Readability
<b>(a)</b>
if ($^O ne "MSWin32") { flock(USERFILE, LOCK_EX); }
if (@fields[1]=~m/^$loginname$/) {
if (@fields[2]=~m/^$password$/) {
$matchokay='true'; # login name matches password
}
}
if ($matchokay) { return $matchokay; }
else { return ''; }
<b>(b)</b>
flock USERFILE, LOCK_EX if $^O ne 'MSWin32';
if ( $user =~ m/^$loginName$/) {
if ( $password =~ m/^$password$/) {
$matchOkay = 'true';
}
}
if ( $matchokay ) {
return $matchokay;
} else {
return '';
}
Example 2: (a) Poorly indented code; (b) Improved indenting.
