Quick Regex question - regex

Question

Can anybody guide me in the right direction...
I have some folder strucktures that I want to check for a trailing / slash, some of the folders don't have a trailing / and if it does not have a trailing
/ I need to add one
If I use this regex it works but it replace the last character of the folder name
Folder/name/test
folder/name/test1/
folder/name/test2/
replace(/.$/ig,"/");
This regex replaces Folder/name/tes[t]/ but will take out the t and replace it with /
Hope this makes sense...

Answer 1

Try something like this:
replace(/[^/]$/ig, "$0/")

Answer 2

replace(/(.)$/ig,"\1/");
or better
replace(/([^\\])$/ig,"\1/");
if \1 isn't a backreference in your language, then you'll have to figure that out, or tell us teh language.

Answer 3

The regex you made basically means this: take any character that is the last one in the string and replace it with /. What you need to do is to group the last character and then insert it again in the replacement, like this:
replace(/([^\/])$/ig,"$1/");

Answer 4

Without knowing the language it's difficult to post a correct answer and you can't use the code provided in a cut-and-paste fashion. Anyway I might go for this regex:
replace(/(.)\/*$/,"\1/");
This will append the trailing / only if it's not there yet.

Answer 5

I'm not sure which language this is for but this is how you would do it in Perl:
#! /local/bin/perl
my #data = <data>;
while (<DATA>)
{
s#[^/]\n#/\n#m;
print;
}
__DATA__
/foo/bar/
/baz/jazz
/baz/jazz
This then prints out the following:
/foo/bar/
/baz/jaz/
/baz/jazz/
The key to the regex is the "[^/]\n" This basically matches anything at the end next to to the newline. With your nomenclature, I would assume the syntax would be the following:
replace(/[^\/]\n/ig,"/");
Or if there is no newline use this:
replace(/[^\/]$/ig,"/");
I hope that helps.

Answer 6

I would avoid a regular expressions in this case and do something easier like:
$path = rtrim($path, '/').'/';
EDIT:
Woops, assumed it was php...
