Hi,

i often need to check whether an array(string) ends with a specific text and if not I need to add this text.

For example I have a variable url and / has to be added to the end in case it is missing.

I want to write:
...new RegistryPackageSupplier(URL(url.enforceSuffix("/"))...

Of course the logic is rather simple to implement on my side but I often has this requirement and I cannot believe this functionality is missing in Phobos.

Have I missed it in the documentation?

Kind regards
André

What about:

	import std.string : chomp;
	url.chomp('/') ~ '/'

The .chomp removes the "/" if there's one, then the ~ adds it back in either way, so the result always ends with "/".

Phobos provides the primitives to build what you need, but it's a little unreasonable to expect that it should provide names for every possible combination of existing functions -- we'd run out of names because of combinatorial explosion.
