This new test was creating an (intentionally invalid) .ruby-version file
in current working directory; typically the rbenv project dir.
Immediately after test runs, I had a leftover .ruby-version file.
The version-file tests create and cd into the RBENV_TEST_DIR as part of
setup(). I'm using the same directory for this test fix, but am only
using it for this particular test. None of the other exec tests seem to
need to be in a temp test dir, so no use putting it in setup().
If subcommand is provided (and exists) and its first arg is -h/--help,
go ahead and intercept the call; redirecting to rbenv-help <subcommand>
This means subcommands and plugins need not handle --help flag
themselves
- Explicitly asking for help with `-h` or `--help` exits with 0 status
and displays help on stdout.
- Not providing any arguments to rbenv results in failure status and
displays version and help on stderr.
Adding a tip for how to view the Homebrew package caveats again if you skipped reading them.
Directing readers to additional next steps after installing pyenv via Homebrew.
Many advanced users who enjoy reading detailed documentation may not really think of themselves as "neckbeards", even in a jokey way, so naming this section with a simple, familiar (and easy-to-translate!) name may encourage more people to read it. :)
Correcting instructions for installing Python versions (removing "download and unpack the source").
Fixing links to #pyenv-shell, #pyenv-local, and #pyenv-global - linking them to the appropriate sections of the COMMANDS.md page.
If `foo` didn't exist and `RBENV_VERSION=system rbenv which foo` was
called, the error message used to be misleading:
rbenv: version `system' is not installed
Instead, have the error message simply say that the command was not found.
Fixes#770
Useful in combination with `--bare` to list just the unique version
numbers without the extra directory entries that are symlinks to other
version numbers in the same directory.
This is for Linux desktop platforms that have Terminal application
configured to start shells in interactive but not login mode. Creating a
`~/.bash_profile` would also cause `~/.profile` to not run, which might
be a problem on Ubuntu which ships with a default `~/.profile`.
