Alias for a class?

Ruby
1

Hi all,

Last night I was playing with some third-party lib and found myself
having to type StupidlyLongLibName::LongModuleName::LongClassName
repeatedly and I wanted a mechanism where I could rename these classes
for my own use to cut down on the finger typing.

I thought I could just do:

class Shortname < OldLongClassName; end

Unfortunately this didn’t work (yes there’s no error thrown, but the
later code expected OldLongClassName and wouldn’t work with Shortname

So my request is:
a: is it possible to alias a class (I know you can do it with methods)?
b: if not can it be added (perhaps with aka)?

Thanks
Kev

You can store that class in any variable or constant you like. So all
of
these work:

$cl = ::StupidlyLongLibName::LongModuleName::LongClassName
@cl = ::StupidlyLongLibName::LongModuleName::LongClassName
@@cl = ::StupidlyLongLibName::LongModuleName::LongClassName
cl = ::StupidlyLongLibName::LongModuleName::LongClassName
Cl = ::StupidlyLongLibName::LongModuleName::LongClassName

Note: depending on where in the code you are some of these do not really
make sense.

Kind regards

You can do this as well:

include StupidlyLongLibName::LongModuleName

however it all stuff from the said module.

That’s an amazingly intuitive comment - wish I’d made that /me ==
jealous…

Thanks for the rest of the insight, but this particular thing rings
true for just about any/all code

d, f, fu = Dir, File, FileUtils

since those three go together in verbose code so often.

w00t! Forget all those silly “constants”!

$d, $f, $fu = Dir, File, FileUtils

Much too readable

*x = Dir, File, FileUtils

who needs names!!!
