* suffix alias where the app has a space in it

I'm trying to use suffix aliases, but I ran into one issue I can't
figure out: What do I do when I want to assign "The Unarchiver" as an
app for archives such as .xz

alias -s  xz="the unarchiver"

But that tries to use 'the' to open 'xz' files.

Is there a way to encode a space in the app name?

I tried googling but either the terms are too vague or no one has
written about this before.

Thanks!

TjL

The thing to remember about aliases is they are expanded very early in
the shell processing --- basically, replacement text is just dumped in
as a raw string where it'll be picked up exactly as is.  So simply
adding a backslash works.

alias -s xz='the\ unarchiver'

alias replacement is token replacement before parsing of the
syntax. That applies to suffix aliases as well. You can even do
something as crazy as:

alias -s xz='for cmd (echo "the unarchiver") $cmd'

And when you enter:

foo.xz

that gets replaced with 

for cmd (echo "the unarchiver") $cmd foo.xz

In your case, just do:

alias -s "xz='the unarchiver'"

Thanks to you (and Stephane) for explaining this. It seems obvious now
that you've explained it.

Cheers,

Tj

Related Question: is there a way to set a default command to use for
all suffixes, and then make additional aliases for other suffixes?

Something like this:

alias -s '*'='open'

or

alias -s \*='open'

and then

alias -s txt='pico'

would override the original.

I tried the first two but neither seemed to work, but there may be a
way that I'm overlooking.

Not with alias.  You could try a command-not-found handler.

What that means is that if you type

% foo.*

then "open foo.*" will be executed.  It does NOT mean that the alias
will be invoked when you type

% foo.bar

Aliases do not do pattern matching.
