replace build system with generated table of contents
Gets rid of `doc/README.mdtoc` and its build script. Since GitHub.com
renders anchors for each heading, all we have to do is put a simple
table of contents into `README.md` itself, and everything will get
linked up nicely.
Pros of this approach:
* We don't have to point out to people not to edit `README.md` anymore
* We don't have to run the build script each time README gets edited
Cons of this change:
* The "chapter" numbers are lost. They were silly anyway.
`doc/mdtoc` renders a Markdown table of contents for a Markdown file.
`doc/filter-toc` filters that down to only headings after ToC.
This script can be used to easily insert ToC into the current document
when editing `README.md` with, e.g., Vim:
:read !doc/filter-toc %

# Simple Ruby Version Management: rbenv
|
||||
|
||||
rbenv lets you easily switch between multiple versions of Ruby. It's
|
||||
simple, unobtrusive, and follows the UNIX tradition of single-purpose
|
||||
tools that do one thing well.
|
||||
|
||||
<img src="http://i.sstephenson.us/rbenv2.png" width="894" height="464">
|
||||
|
||||
### rbenv _does…_
|
||||
|
||||
* Let you **change the global Ruby version** on a per-user basis.
|
||||
* Provide support for **per-project Ruby versions**.
|
||||
* Allow you to **override the Ruby version** with an environment
|
||||
variable.
|
||||
|
||||
### In contrast with rvm, rbenv _does not…_
|
||||
|
||||
* **Need to be loaded into your shell.** Instead, rbenv's shim
|
||||
approach works by adding a directory to your `$PATH`.
|
||||
* **Override shell commands like `cd`.** That's dangerous and
|
||||
error-prone.
|
||||
* **Have a configuration file.** There's nothing to configure except
|
||||
which version of Ruby you want to use.
|
||||
* **Install Ruby.** You can build and install Ruby yourself, or use
|
||||
[ruby-build](https://github.com/sstephenson/ruby-build) to
|
||||
automate the process.
|
||||
* **Manage gemsets.** [Bundler](http://gembundler.com/) is a better
|
||||
way to manage application dependencies. If you have projects that
|
||||
are not yet using Bundler you can install the
|
||||
[rbenv-gemset](https://github.com/jamis/rbenv-gemset) plugin.
|
||||
* **Require changes to Ruby libraries for compatibility.** The
|
||||
simplicity of rbenv means as long as it's in your `$PATH`,
|
||||
[nothing](https://rvm.io/integration/bundler/)
|
||||
[else](https://rvm.io/integration/capistrano/)
|
||||
needs to know about it.
|
||||
* **Prompt you with warnings when you switch to a project.** Instead
|
||||
of executing arbitrary code, rbenv reads just the version name
|
||||
from each project. There's nothing to "trust."
|
||||
|
||||
## Table of Contents
|
||||
|
||||
## How It Works ##
|
||||
|
||||
rbenv operates on the per-user directory `~/.rbenv`. Version names in
|
||||
rbenv correspond to subdirectories of `~/.rbenv/versions`. For
|
||||
example, you might have `~/.rbenv/versions/1.8.7-p354` and
|
||||
`~/.rbenv/versions/1.9.3-p327`.
|
||||
|
||||
Each version is a working tree with its own binaries, like
|
||||
`~/.rbenv/versions/1.8.7-p354/bin/ruby` and
|
||||
`~/.rbenv/versions/1.9.3-p327/bin/irb`. rbenv makes _shim binaries_
|
||||
for every such binary across all installed versions of Ruby.
|
||||
|
||||
These shims are simple wrapper scripts that live in `~/.rbenv/shims`
|
||||
and detect which Ruby version you want to use. They insert the
|
||||
directory for the selected version at the beginning of your `$PATH`
|
||||
and then execute the corresponding binary.
|
||||
|
||||
Because of the simplicity of the shim approach, all you need to use
|
||||
rbenv is `~/.rbenv/shims` in your `$PATH`.
|
||||
|
||||
## Installation ##
|
||||
|
||||
**Compatibility note**: rbenv is _incompatible_ with rvm. Things will
|
||||
appear to work until you try to install a gem. The problem is that
|
||||
rvm actually overrides the `gem` command with a shell function!
|
||||
Please remove any references to rvm before using rbenv.
|
||||
|
||||
### Basic GitHub Checkout ###
|
||||
|
||||
This will get you going with the latest version of rbenv and make it
|
||||
easy to fork and contribute any changes back upstream.
|
||||
|
||||
1. Check out rbenv into `~/.rbenv`.
|
||||
|
||||
$ git clone git://github.com/sstephenson/rbenv.git ~/.rbenv
|
||||
|
||||
2. Add `~/.rbenv/bin` to your `$PATH` for access to the `rbenv`
|
||||
command-line utility.
|
||||
|
||||
$ echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bash_profile
|
||||
|
||||
**Zsh note**: Modify your `~/.zshenv` file instead of `~/.bash_profile`.
|
||||
|
||||
**Ubuntu note**: Ubuntu uses `~/.profile` for enabling certain path
|
||||
changes. This file won't be read if you create a `~/.bash_profile`.
|
||||
Therefore, it's recommended that you add this line and the one in
|
||||
point 3 below to your `~/.profile`. This has the added advantage
|
||||
of working under both bash and zsh.
|
||||
|
||||
3. Add rbenv init to your shell to enable shims and autocompletion.
|
||||
|
||||
$ echo 'eval "$(rbenv init -)"' >> ~/.bash_profile
|
||||
|
||||
**Zsh note**: Modify your `~/.zshenv` file instead of `~/.bash_profile`.
|
||||
|
||||
**Ubuntu note**: Same as Ubuntu note for point 2 above.
|
||||
|
||||
4. Restart your shell as a login shell so the path changes take effect.
|
||||
You can now begin using rbenv.
|
||||
|
||||
$ exec $SHELL -l
|
||||
|
||||
5. Install Ruby versions into `~/.rbenv/versions`. For example, to
|
||||
install Ruby 1.9.3-p327, download and unpack the source, then run:
|
||||
|
||||
$ ./configure --prefix=$HOME/.rbenv/versions/1.9.3-p327
|
||||
$ make
|
||||
$ make install
|
||||
|
||||
The [ruby-build](https://github.com/sstephenson/ruby-build) project
|
||||
provides an `rbenv install` command that simplifies the process of
|
||||
installing new Ruby versions to:
|
||||
|
||||
$ rbenv install 1.9.3-p327
|
||||
|
||||
6. Rebuild the shim binaries. You should do this any time you install
|
||||
a new Ruby binary (for example, when installing a new Ruby version,
|
||||
or when installing a gem that provides a binary).
|
||||
|
||||
$ rbenv rehash
|
||||
|
||||
#### Upgrading ####
|
||||
|
||||
If you've installed rbenv using the instructions above, you can
|
||||
upgrade your installation at any time using git.
|
||||
|
||||
To upgrade to the latest development version of rbenv, use `git pull`:
|
||||
|
||||
$ cd ~/.rbenv
|
||||
$ git pull
|
||||
|
||||
To upgrade to a specific release of rbenv, check out the corresponding
|
||||
tag:
|
||||
|
||||
$ cd ~/.rbenv
|
||||
$ git fetch
|
||||
$ git tag
|
||||
v0.1.0
|
||||
v0.1.1
|
||||
v0.1.2
|
||||
v0.2.0
|
||||
$ git checkout v0.2.0
|
||||
|
||||
### Homebrew on Mac OS X ###
|
||||
|
||||
You can also install rbenv using the
|
||||
[Homebrew](http://mxcl.github.com/homebrew/) package manager on Mac OS
|
||||
X.
|
||||
|
||||
$ brew update
|
||||
$ brew install rbenv
|
||||
$ brew install ruby-build
|
||||
|
||||
The same commands can be used for upgrading.
|
||||
|
||||
Afterwards you'll still need to add `eval "$(rbenv init -)"` to your
|
||||
profile as stated in the caveats. You'll only ever have to do this
|
||||
once.
|
||||
|
||||
### Neckbeard Configuration ###
|
||||
|
||||
Skip this section unless you must know what every line in your shell
|
||||
profile is doing.
|
||||
|
||||
`rbenv init` is the only command that crosses the line of loading
|
||||
extra commands into your shell. Coming from rvm, some of you might be
|
||||
opposed to this idea. Here's what `rbenv init` actually does:
|
||||
|
||||
1. Sets up your shims path. This is the only requirement for rbenv to
|
||||
function properly. You can do this by hand by prepending
|
||||
`~/.rbenv/shims` to your `$PATH`.
|
||||
|
||||
2. Installs autocompletion. This is entirely optional but pretty
|
||||
useful. Sourcing `~/.rbenv/completions/rbenv.bash` will set that
|
||||
up. There is also a `~/.rbenv/completions/rbenv.zsh` for Zsh
|
||||
users.
|
||||
|
||||
3. Rehashes shims. From time to time you'll need to rebuild your
|
||||
shim files. Doing this on init makes sure everything is up to
|
||||
date. You can always run `rbenv rehash` manually.
|
||||
|
||||
4. Installs the sh dispatcher. This bit is also optional, but allows
|
||||
rbenv and plugins to change variables in your current shell, making
|
||||
commands like `rbenv shell` possible. The sh dispatcher doesn't do
|
||||
anything crazy like override `cd` or hack your shell prompt, but if
|
||||
for some reason you need `rbenv` to be a real script rather than a
|
||||
shell function, you can safely skip it.
|
||||
|
||||
Run `rbenv init -` for yourself to see exactly what happens under the
|
||||
hood.
|
||||
|
||||
### Uninstalling Ruby Versions ###
|
||||
|
||||
As time goes on, ruby versions you install will accumulate in your
|
||||
`~/.rbenv/versions` directory.
|
||||
|
||||
There is no uninstall or remove command in `rbenv`, so removing old
|
||||
versions is a simple matter of `rm -rf` the directory of the relevant
|
||||
ruby version you want removed under `~/.rbenv/versions`
|
||||
|
||||
## Usage ##
|
||||
|
||||
Like `git`, the `rbenv` command delegates to subcommands based on its
|
||||
first argument. The most common subcommands are:
|
||||
|
||||
### rbenv global ###
|

Sets the global version of Ruby to be used in all shells by writing
|
||||
the version name to the `~/.rbenv/version` file. This version can be
|
||||
overridden by a per-project `.rbenv-version` file, or by setting the
|
||||
`RBENV_VERSION` environment variable.
|
||||
|
||||
$ rbenv global 1.9.3-p327
|
||||
|
||||
The special version name `system` tells rbenv to use the system Ruby
|
||||
(detected by searching your `$PATH`).
|
||||
|
||||
When run without a version number, `rbenv global` reports the
|
||||
currently configured global version.
|
||||
|
||||
### rbenv local ###
|
||||
|
||||
Sets a local per-project Ruby version by writing the version name to
|
||||
an `.rbenv-version` file in the current directory. This version
|
||||
overrides the global, and can be overridden itself by setting the
|
||||
`RBENV_VERSION` environment variable or with the `rbenv shell`
|
||||
command.
|
||||
|
||||
$ rbenv local rbx-1.2.4
|
||||
|
||||
When run without a version number, `rbenv local` reports the currently
|
||||
configured local version. You can also unset the local version:
|
||||
|
||||
$ rbenv local --unset
|
||||
|
||||
### rbenv shell ###
|
||||
|
||||
Sets a shell-specific Ruby version by setting the `RBENV_VERSION`
|
||||
environment variable in your shell. This version overrides both
|
||||
project-specific versions and the global version.
|
||||
|
||||
$ rbenv shell jruby-1.7.1
|
||||
|
||||
When run without a version number, `rbenv shell` reports the current
|
||||
value of `RBENV_VERSION`. You can also unset the shell version:
|
||||
|
||||
$ rbenv shell --unset
|
||||
|
||||
Note that you'll need rbenv's shell integration enabled (step 3 of
|
||||
the installation instructions) in order to use this command. If you
|
||||
prefer not to use shell integration, you may simply set the
|
||||
`RBENV_VERSION` variable yourself:
|
||||
|
||||
$ export RBENV_VERSION=jruby-1.7.1
|
||||
|
||||
### rbenv versions ###
|
||||
|
||||
Lists all Ruby versions known to rbenv, and shows an asterisk next to
|
||||
the currently active version.
|
||||
|
||||
$ rbenv versions
|
||||
1.8.7-p352
|
||||
1.9.2-p290
|
||||
* 1.9.3-p327 (set by /Users/sam/.rbenv/global)
|
||||
jruby-1.7.1
|
||||
rbx-1.2.4
|
||||
ree-1.8.7-2011.03
|
||||
|
||||
### rbenv version ###
|
||||
|
||||
Displays the currently active Ruby version, along with information on
|
||||
how it was set.
|
||||
|
||||
$ rbenv version
|
||||
1.8.7-p352 (set by /Volumes/37signals/basecamp/.rbenv-version)
|
||||
|
||||
### rbenv rehash ###
|
||||
|
||||
Installs shims for all Ruby binaries known to rbenv (i.e.,
|
||||
`~/.rbenv/versions/*/bin/*`). Run this command after you install a new
|
||||
version of Ruby, or install a gem that provides binaries.
|
||||
|
||||
$ rbenv rehash
|
||||
|
||||
### rbenv which ###
|
||||
|
||||
Displays the full path to the binary that rbenv will execute when you
|
||||
run the given command.
|
||||
|
||||
$ rbenv which irb
|
||||
/Users/sam/.rbenv/versions/1.9.3-p327/bin/irb
|
||||
|
||||
### rbenv whence ###
|
||||
|
||||
Lists all Ruby versions with the given command installed.
|
||||
|
||||
$ rbenv whence rackup
|
||||
1.9.3-p327
|
||||
jruby-1.7.1
|
||||
ree-1.8.7-2011.03

|
||||
## Development ##
|
||||
|
||||
The rbenv source code is [hosted on
|
||||
GitHub](https://github.com/sstephenson/rbenv). It's clean, modular,
|
||||
and easy to understand, even if you're not a shell hacker.
|
||||

||||
### Version History ###
|
||||
|
||||
**0.3.0** (December 25, 2011)
|
||||
|
||||
* Added an `rbenv root` command which prints the value of
|
||||
`$RBENV_ROOT`, or the default root directory if it's unset.
|
||||
* Clarified Zsh installation instructions in the readme.
|
||||
* Removed some redundant code in `rbenv rehash`.
|
||||
* Fixed an issue with calling `readlink` for paths with spaces.
|
||||
* Changed Zsh initialization code to install completion hooks only for
|
||||
interactive shells.
|
||||
* Added preliminary support for ksh.
|
||||
* `rbenv rehash` creates or removes shims only when necessary instead
|
||||
of removing and re-creating all shims on each invocation.
|
||||
* Fixed that `RBENV_DIR`, when specified, would be incorrectly
|
||||
expanded to its parent directory.
|
||||
* Removed the deprecated `set-default` and `set-local` commands.
|
||||
* Added a `--no-rehash` option to `rbenv init` for skipping the
|
||||
automatic rehash when opening a new shell.
|
||||
|
||||
**0.2.1** (October 1, 2011)
|
||||
|
||||
* Changed the `rbenv` command to ensure that `RBENV_DIR` is always an
|
||||
absolute path. This fixes an issue where Ruby scripts using the
|
||||
`ruby-local-exec` wrapper would go into an infinite loop when
|
||||
invoked with a relative path from the command line.
|
||||
|
||||
**0.2.0** (September 28, 2011)
|
||||
|
||||
* Renamed `rbenv set-default` to `rbenv global` and `rbenv set-local`
|
||||
to `rbenv local`. The `set-` commands are deprecated and will be
|
||||
removed in the next major release.
|
||||
* rbenv now uses `greadlink` on Solaris.
|
||||
* Added a `ruby-local-exec` command which can be used in shebangs in
|
||||
place of `#!/usr/bin/env ruby` to properly set the project-specific
|
||||
Ruby version regardless of current working directory.
|
||||
* Fixed an issue with `rbenv rehash` when no binaries are present.
|
||||
* Added support for `rbenv-sh-*` commands, which run inside the
|
||||
current shell instead of in a child process.
|
||||
* Added an `rbenv shell` command for conveniently setting the
|
||||
`$RBENV_VERSION` environment variable.
|
||||
* Added support for storing rbenv versions and shims in directories
|
||||
other than `~/.rbenv` with the `$RBENV_ROOT` environment variable.
|
||||
* Added support for debugging rbenv via `set -x` when the
|
||||
`$RBENV_DEBUG` environment variable is set.
|
||||
* Refactored the autocompletion system so that completions are now
|
||||
built-in to each command and shared between bash and Zsh.
|
||||
* Added support for plugin bundles in `~/.rbenv/plugins` as documented
|
||||
in [issue #102](https://github.com/sstephenson/rbenv/pull/102).
|
||||
* Added `/usr/local/etc/rbenv.d` to the list of directories searched
|
||||
for rbenv hooks.
|
||||
* Added support for an `$RBENV_DIR` environment variable which
|
||||
defaults to the current working directory for specifying where rbenv
|
||||
searches for local version files.
|
||||
|
||||
**0.1.2** (August 16, 2011)
|
||||
|
||||
* Fixed rbenv to be more resilient against nonexistent entries in
|
||||
`$PATH`.
|
||||
* Made the `rbenv rehash` command operate atomically.
|
||||
* Modified the `rbenv init` script to automatically run `rbenv
|
||||
rehash` so that shims are recreated whenever a new shell is opened.
|
||||
* Added initial support for Zsh autocompletion.
|
||||
* Removed the dependency on egrep for reading version files.
|
||||
|
||||
**0.1.1** (August 14, 2011)
|
||||
|
||||
* Fixed a syntax error in the `rbenv help` command.
|
||||
* Removed `-e` from the shebang in favor of `set -e` at the top of
|
||||
each file for compatibility with operating systems that do not
|
||||
support more than one argument in the shebang.
|
||||
|
||||
**0.1.0** (August 11, 2011)
|
||||
|
||||
* Initial public release.
