It's slow and not necessary since we expect `$0` to already be expanded.
In tests this change forces us to deal with some relative paths, but
it's not a big deal. The `rbenv init -` output in the most common case
will be the same as before:
source '/home/myuser/.rbenv/libexec/../completions/rbenv.bash'
With `realpath` extension, hooks tests on OS X will output
`/private/tmp` instead of `/tmp` because the latter is an actual symlink
to the former.
Avoid this mistmach in output assertions by expanding BATS_TMPDIR if
`realpath` extension is compiled.
On other systems, we expected to find system Ruby in `/usr/bin`, but in
OpenBSD 5.4 it will be found in `/usr/local/bin`.
This replaces the limited USRBIN_ALT hack with a more generic
`path_without` function that will ensure that the given executable is
not present in the resulting PATH even if it's found in multiple
system paths.
The error was "bash: no such file or directory" and it was due to bash
being located in `/usr/local/bin` on OpenBSD 5.4 instead of `/bin` like
on other systems.
Fixed by keeping `/usr/local/bin` in PATH during the test run.
Fish user config file `~/.config/fish/config.fish` loads for every
instance of fish shell, not just interactive ones. Since it's
unnecessary and dangerous to eval `rbenv init -` output in
non-interactive shells, wrap the invocation in a conditional that checks
if the current shell is interactive.

It was supposed to fix shelling out to Ruby but it in fact broke another
kind of shelling out to Ruby: invoking the `ruby` binary directly with
the `-S` flag.

This reverts commit db143bb654.
It doesn't exist as a builtin, and it doesn't seem there is a way to
detect support for a shell builtin that is portable. So, just detect
fish and don't the rehash command at all.
Fixes#478
`$SHELL` variable is a terrible way of detecting the current shell
because it's not even supposed to reflect the current shell; it's meant
for keeping the value of the default shell for programs to start.
If an explicit `<shell>` argument wasn't passed to `rbenv init`, it
tries to detect the shell by getting the name of its parent process. If
this fails, it falls back on the value of `$SHELL` as before.
Furthermore, `rbenv init` will set the RBENV_SHELL variable in the
current shell to the value of the detected shell so that `sh-shell` and
`sh-rehash` commands don't have to repeat the detection.
If `rbenv init -` outputs `.` in place of `source` and that gets eval'd
by the desktop manager via `~/.profile`, it chokes and prevents the user
from logging in.
Fixes#457
Enables shelling out from a ruby process started with rbenv to a ruby
process with a different RBENV_VERSION. Fixes#121
This removes the workaround created for #15 and solves `ruby -S` support
by setting RUBYPATH. PATH is never changed.
To illustrate how RUBYPATH changes in various configurations:
PATH=~/bin:~/.rbenv/shims:/usr/bin:/bin
RBENV_VERSION=1.8 ruby -S rake
#=> executes ~/.rbenv/versions/1.8/bin/rake
#=> RUBYPATH=~/bin:~/.rbenv/versions/1.8/bin:/usr/bin:/bin
RBENV_VERSION=2.0 ruby -S rake
#=> executes ~/.rbenv/versions/2.0/bin/rake
#=> RUBYPATH=~/bin:~/.rbenv/versions/2.0/bin:/usr/bin:/bin
RBENV_VERSION=system ruby -S rake
#=> executes /usr/bin/rake
#=> RUBYPATH=~/bin:/rbenv_shims_were_here:/usr/bin:/bin
RBENV_VERSION=1.8 ruby -S rake
#=> executes ~/.rbenv/versions/1.8/bin/rake
#=> RUBYPATH=~/bin:~/.rbenv/versions/1.8/bin:/usr/bin:/bin
