Re: Using 'lc' (lowercase) in a reg ex

If you want to use commands in regex, you need to use /e in there.

$newfile =~ s/\b([A-Z]{2,})\b/\\emph{lc($1)}/ge;
[download]

Another way would be to use metasymbols

$newfile =~ s/\b([A-Z]{2,})\b/\\emph{\L$1\E}/g;
[download]

Code above untested, so might have mistakes.

`$newfile =~ s/\b([A-Z]{2,})\b/\\emph{lc($1)}/ge;` [download] Unless you happen to have a function called `emph`, that's not going to work. If you want to use `/e`, write it as: `$newfile =~ s/\b([A-Z]{2,})\b/'\emph{' . lc ($1) . '}'/eg;` [download] But I would go for the `\L` method. Abigail	[reply] [d/l] [select]
