I think Fish command substitutions are treated as background processes. It
looks like the `ssh` command is being stopped (see `jobs`), and if you resume
it, it complains that tcsetattr() was interrupted. The documentation on
tcsetattr() says:

Ok, thanks for all support.
To summarise, the problem comes from the pseudo-tty assignment in ssh. When
something in a command substitution (command) assign a pseudo-tty fish
replaces this with nothing (and actually swallow surrounding text ?!).
Disabling pseudo-tty allocation solves this.
For re
This got me at first too. Command substitution returns a *list*, not just a
string. When you prefix a list with a string ("http://";), that string is
prefixed onto each member of the list:
$ function tmp; echo 1; echo 2; echo 3; end
$ echo "foo"(tmp)
foo1 foo2 foo3
If the list is empty, the strin

Sorry, replying to all this time:
I can actually reproduce this without vagrant.
>From skimming the source, vagrant expands to something like:
ssh -t "/bin/bash -c ''"
so, my equivalent function is:
function x_test
ssh -t "/bin/bash -c 'echo hi'" ^ /dev/null
end
If i define this, an
What is strange is that
$ echo "http://";(vip)
outputs only a new line. I would expect it to at least printout:
http://

I do not know of the "vagrant" command. Does it really output data to
stdout? (and not stderr, for instance)
What does:
$ echo "http://";(vip)
outputs?

To boil it down a bit. Why is this having as it does:
$ vip ^/dev/null
192.168.233.170
$ echo "ip:"(vip)"-"

Hi,
It turns out that is the function creating the url that is not working as I
expected. This is the actual code:
function vip
vagrant ssh $argv[1] -c "ifconfig eth1 | sed -ne 's/.*inet
addr:\(\S*\)\s*Bcast.*/\1/p'" \
^ /dev/null
end
Using it gives:
$ vip
192.168.233.170
But running:
$ o
Works perfectly for me:

Hi,
If i have a function that computes an URL, say:
function url
echo "some url"
end
Then I want to use it in a command substitution. Something like:
open (url)/index.html
but (url) is expanded to empty string. How should I do this?
