| brew(1) -- The missing package manager for OS X
 | |
| ===============================================
 | |
| 
 | |
| ## SYNOPSIS
 | |
| 
 | |
| `brew` --version<br>
 | |
| `brew` command [--verbose|-v] [options] [formula] ...
 | |
| 
 | |
| ## DESCRIPTION
 | |
| 
 | |
| Homebrew is the easiest and most flexible way to install the UNIX tools Apple
 | |
| didn't include with OS X.
 | |
| 
 | |
| ## ESSENTIAL COMMANDS
 | |
| 
 | |
| For the full command list, see the COMMANDS section.
 | |
| 
 | |
| With `--verbose` or `-v`, many commands print extra debugging information.
 | |
| Note that these flags should only appear after a command.
 | |
| 
 | |
|   * `install` <formula>:
 | |
|     Install <formula>.
 | |
| 
 | |
|   * `remove` <formula>:
 | |
|     Uninstall <formula>.
 | |
| 
 | |
|   * `update`:
 | |
|     Fetch the newest version of Homebrew from GitHub using `git`(1).
 | |
| 
 | |
|   * `list`:
 | |
|     List all installed formulae.
 | |
| 
 | |
|   * `search` <text>|/<text>/:
 | |
|     Perform a substring search of formula names for <text>. If <text> is
 | |
|     surrounded with slashes, then it is interpreted as a regular expression.
 | |
|     The search for <text> is extended online to some popular taps.
 | |
|     If no search term is given, all locally available formulae are listed.
 | |
| 
 | |
| ## COMMANDS
 | |
| 
 | |
|   * `audit` [--strict] [<formulae>]:
 | |
|     Check <formulae> for Homebrew coding style violations. This should be
 | |
|     run before submitting a new formula.
 | |
| 
 | |
|     If no <formulae> are provided, all of them are checked.
 | |
| 
 | |
|     If `--strict` is passed, additional checks are run. This should be used
 | |
|     when creating for new formulae.
 | |
| 
 | |
|     `audit` exits with a non-zero status if any errors are found. This is useful,
 | |
|     for instance, for implementing pre-commit hooks.
 | |
| 
 | |
|   * `cat` <formula>:
 | |
|     Display the source to <formula>.
 | |
| 
 | |
|   * `cleanup [--force] [--prune=<days>] [-ns]` [<formulae>]:
 | |
|     For all installed or specific formulae, remove any older versions from the
 | |
|     cellar. By default, does not remove out-of-date keg-only brews, as other
 | |
|     software may link directly to specific versions. In addition old downloads from
 | |
|     the Homebrew download-cache are deleted.
 | |
| 
 | |
|     If `--force` is passed, remove out-of-date keg-only brews as well.
 | |
| 
 | |
|     If `--prune=<days>` is specified, remove all cache files older than <days>.
 | |
| 
 | |
|     If `-n` is passed, show what would be removed, but do not actually remove anything.
 | |
| 
 | |
|     If `-s` is passed, scrubs the cache, removing downloads for even the latest
 | |
|     versions of formula. Note downloads for any installed formula will still not be
 | |
|     deleted. If you want to delete those too: `rm -rf $(brew --cache)`
 | |
| 
 | |
|   * `commands`:
 | |
|     Show a list of built-in and external commands.
 | |
| 
 | |
|   * `config`:
 | |
|     Show Homebrew and system configuration useful for debugging. If you file
 | |
|     a bug report, you will likely be asked for this information if you do not
 | |
|     provide it.
 | |
| 
 | |
|   * `create <URL> [--autotools|--cmake] [--no-fetch] [--set-name <name>] [--set-version <version>]`:
 | |
|     Generate a formula for the downloadable file at <URL> and open it in the editor.
 | |
|     Homebrew will attempt to automatically derive the formula name
 | |
|     and version, but if it fails, you'll have to make your own template. The wget
 | |
|     formula serves as a simple example. For a complete cheat-sheet, have a look at
 | |
| 
 | |
|     `$(brew --repository)/Library/Contributions/example-formula.rb`
 | |
| 
 | |
|     If `--autotools` is passed, create a basic template for an Autotools-style build.
 | |
|     If `--cmake` is passed, create a basic template for a CMake-style build.
 | |
| 
 | |
|     If `--no-fetch` is passed, Homebrew will not download <URL> to the cache and
 | |
|     will thus not add the SHA-1 to the formula for you.
 | |
| 
 | |
|     The options `--set-name` and `--set-version` each take an argument and allow
 | |
|     you to explicitly set the name and version of the package you are creating.
 | |
| 
 | |
|   * `deps [--1] [-n] [--union] [--tree] [--all] [--installed] [--skip-build] [--skip-optional]` <formulae>:
 | |
|     Show dependencies for <formulae>. When given multiple formula arguments,
 | |
|     show the intersection of dependencies for <formulae>, except when passed
 | |
|     `--tree`, `--all`, or `--installed`.
 | |
| 
 | |
|     If `--1` is passed, only show dependencies one level down, instead of
 | |
|     recursing.
 | |
| 
 | |
|     If `-n` is passed, show dependencies in topological order.
 | |
| 
 | |
|     If `--union` is passed, show the union of dependencies for <formulae>,
 | |
|     instead of the intersection.
 | |
| 
 | |
|     If `--tree` is passed, show dependencies as a tree.
 | |
| 
 | |
|     If `--all` is passed, show dependencies for all formulae.
 | |
| 
 | |
|     If `--installed` is passed, show dependencies for all installed formulae.
 | |
| 
 | |
|     By default, `deps` shows dependencies for <formulae>. To skip the `:build`
 | |
|     type dependencies, pass `--skip-build`. Similarly, pass `--skip-optional`
 | |
|     to skip `:optional` dependencies.
 | |
| 
 | |
|   * `diy [--name=<name>] [--version=<version>]`:
 | |
|     Automatically determine the installation prefix for non-Homebrew software.
 | |
| 
 | |
|     Using the output from this command, you can install your own software into
 | |
|     the Cellar and then link it into Homebrew's prefix with `brew link`.
 | |
| 
 | |
|     The options `--name=<name>` and `--version=<version>` each take an argument
 | |
|     and allow you to explicitly set the name and version of the package you are
 | |
|     installing.
 | |
| 
 | |
|   * `doctor`:
 | |
|     Check your system for potential problems. Doctor exits with a non-zero status
 | |
|     if any problems are found.
 | |
| 
 | |
|   * `edit`:
 | |
|     Open all of Homebrew for editing.
 | |
| 
 | |
|   * `edit` <formula>:
 | |
|     Open <formula> in the editor.
 | |
| 
 | |
|   * `fetch [--force] [-v] [--devel|--HEAD] [--deps] [--build-from-source|--force-bottle]` <formulae>:
 | |
|     Download the source packages for the given <formulae>.
 | |
|     For tarballs, also print SHA1 and SHA-256 checksums.
 | |
| 
 | |
|     If `--HEAD` or `--devel` is passed, fetch that version instead of the
 | |
|     stable version.
 | |
| 
 | |
|     If `-v` is passed, do a verbose VCS checkout, if the url represents a CVS.
 | |
|     This is useful for seeing if an existing VCS cache has been updated.
 | |
| 
 | |
|     If `--force` is passed, remove a previously cached version and re-fetch.
 | |
| 
 | |
|     If `--deps` is passed, also download dependencies for any listed <formulae>.
 | |
| 
 | |
|     If `--build-from-source` is passed, download the source rather than a
 | |
|     bottle.
 | |
| 
 | |
|     If `--force-bottle` is passed, download a bottle if it exists for the current
 | |
|     version of OS X, even if it would not be used during installation.
 | |
| 
 | |
|   * `home`:
 | |
|     Open Homebrew's own homepage in a browser.
 | |
| 
 | |
|   * `home` <formula>:
 | |
|     Open <formula>'s homepage in a browser.
 | |
| 
 | |
|   * `info` <formula>:
 | |
|     Display information about <formula>.
 | |
| 
 | |
|   * `info --github` <formula>:
 | |
|     Open a browser to the GitHub History page for formula <formula>.
 | |
| 
 | |
|     To view formula history locally: `brew log -p <formula>`.
 | |
| 
 | |
|   * `info --json=<version>` (--all|--installed|<formulae>):
 | |
|     Print a JSON representation of <formulae>. Currently the only accepted value
 | |
|     for <version> is `v1`.
 | |
| 
 | |
|     Pass `--all` to get information on all formulae, or `--installed` to get
 | |
|     information on all installed formulae.
 | |
| 
 | |
|     See the docs for examples of using the JSON:
 | |
|     <https://github.com/Homebrew/homebrew/blob/master/share/doc/homebrew/Querying-Brew.md>
 | |
| 
 | |
|   * `install [--debug] [--env=<std|super>] [--ignore-dependencies] [--only-dependencies] [--cc=<compiler>] [--build-from-source] [--devel|--HEAD]` <formula>:
 | |
|     Install <formula>.
 | |
| 
 | |
|     <formula> is usually the name of the formula to install, but it can be specified
 | |
|     several different ways. See [SPECIFYING FORMULAE][].
 | |
| 
 | |
|     If `--debug` is passed and brewing fails, open an interactive debugging
 | |
|     session with access to IRB or a shell inside the temporary build directory.
 | |
| 
 | |
|     If `--env=std` is passed, use the standard build environment instead of superenv.
 | |
| 
 | |
|     If `--env=super` is passed, use superenv even if the formula specifies the
 | |
|     standard build environment.
 | |
| 
 | |
|     If `--ignore-dependencies` is passed, skip installing any dependencies of
 | |
|     any kind. If they are not already present, the formula will probably fail
 | |
|     to install.
 | |
| 
 | |
|     If `--only-dependencies` is passed, install the dependencies with specified
 | |
|     options but do not install the specified formula.
 | |
| 
 | |
|     If `--cc=<compiler>` is passed, attempt to compile using <compiler>.
 | |
|     <compiler> should be the name of the compiler's executable, for instance
 | |
|     `gcc-4.2` for Apple's GCC 4.2, or `gcc-4.9` for a Homebrew-provided GCC
 | |
|     4.9.
 | |
| 
 | |
|     If `--build-from-source` is passed, compile from source even if a bottle
 | |
|     is provided for <formula>.
 | |
| 
 | |
|     If `--devel` is passed, and <formula> defines it, install the development version.
 | |
| 
 | |
|     If `--HEAD` is passed, and <formula> defines it, install the HEAD version,
 | |
|     aka master, trunk, unstable.
 | |
| 
 | |
|     To install a newer version of HEAD use
 | |
|     `brew rm <foo> && brew install --HEAD <foo>`.
 | |
| 
 | |
|   * `install --interactive [--git]` <formula>:
 | |
|     Download and patch <formula>, then open a shell. This allows the user to
 | |
|     run `./configure --help` and otherwise determine how to turn the software
 | |
|     package into a Homebrew formula.
 | |
| 
 | |
|     If `--git` is passed, Homebrew will create a Git repository, useful for
 | |
|     creating patches to the software.
 | |
| 
 | |
|   * `irb [--example]`:
 | |
|     Enter the interactive Homebrew Ruby shell.
 | |
| 
 | |
|     If `--example` is passed, several examples will be shown.
 | |
| 
 | |
|   * `leaves`:
 | |
|     Show installed formulae that are not dependencies of another installed formula.
 | |
| 
 | |
|   * `ln`, `link [--overwrite] [--dry-run] [--force]` <formula>:
 | |
|     Symlink all of <formula>'s installed files into the Homebrew prefix. This
 | |
|     is done automatically when you install formula, but can be useful for DIY
 | |
|     installations.
 | |
| 
 | |
|     If `--overwrite` is passed, Homebrew will delete files which already exist in
 | |
|     the prefix while linking.
 | |
| 
 | |
|     If `--dry-run` or `-n` is passed, Homebrew will list all files which would
 | |
|     be linked or which would be deleted by `brew link --overwrite`, but will not
 | |
|     actually link or delete any files.
 | |
| 
 | |
|     If `--force` is passed, Homebrew will allow keg-only formulae to be linked.
 | |
| 
 | |
|   * `linkapps [--local]` [<formulae>]:
 | |
|     Find installed formulae that have compiled `.app`-style "application"
 | |
|     packages for OS X, and symlink those apps into `/Applications`, allowing
 | |
|     for easier access.
 | |
| 
 | |
|     If no <formulae> are provided, all of them will have their .apps symlinked.
 | |
| 
 | |
|     If provided, `--local` will move them into the user's `~/Applications`
 | |
|     directory instead of the system directory. It may need to be created, first.
 | |
| 
 | |
|   * `ls, list [--unbrewed] [--versions [--multiple]] [--pinned]` [<formulae>]:
 | |
|     Without any arguments, list all installed formulae.
 | |
| 
 | |
|     If <formulae> are given, list the installed files for <formulae>.
 | |
|     Combined with `--verbose`, recursively list the contents of all subdirectories
 | |
|     in each <formula>'s keg.
 | |
| 
 | |
|     If `--unbrewed` is passed, list all files in the Homebrew prefix not installed
 | |
|     by Homebrew.
 | |
| 
 | |
|     If `--versions` is passed, show the version number for installed formulae,
 | |
|     or only the specified formulae if <formulae> are given. With `--multiple`,
 | |
|     only show formulae with multiple versions installed.
 | |
| 
 | |
|     If `--pinned` is passed, show the versions of pinned formulae, or only the
 | |
|     specified (pinned) formulae if <formulae> are given.
 | |
|     See also `pin`, `unpin`.
 | |
| 
 | |
|   * `log [git-log-options]` <formula> ...:
 | |
|     Show the git log for the given formulae. Options that `git-log`(1)
 | |
|     recognizes can be passed before the formula list.
 | |
| 
 | |
|   * `missing` [<formulae>]:
 | |
|     Check the given <formulae> for missing dependencies.
 | |
| 
 | |
|     If no <formulae> are given, check all installed brews.
 | |
| 
 | |
|   * `options [--compact] [--all] [--installed]` <formula>:
 | |
|     Display install options specific to <formula>.
 | |
| 
 | |
|     If `--compact` is passed, show all options on a single line separated by
 | |
|     spaces.
 | |
| 
 | |
|     If `--all` is passed, show options for all formulae.
 | |
| 
 | |
|     If `--installed` is passed, show options for all installed formulae.
 | |
| 
 | |
|   * `outdated [--quiet|--verbose]`:
 | |
|     Show formulae that have an updated version available.
 | |
| 
 | |
|     By default, version information is displayed in interactive shells, and
 | |
|     suppressed otherwise.
 | |
| 
 | |
|     If `--quiet` is passed, list only the names of outdated brews (takes
 | |
|     precedence over `--verbose`).
 | |
| 
 | |
|     If `--verbose` is passed, display detailed version information.
 | |
| 
 | |
|   * `pin` <formulae>:
 | |
|     Pin the specified <formulae>, preventing them from being upgraded when
 | |
|     issuing the `brew upgrade --all` command. See also `unpin`.
 | |
| 
 | |
|   * `prune`:
 | |
|     Remove dead symlinks from the Homebrew prefix. This is generally not
 | |
|     needed, but can be useful when doing DIY installations.
 | |
| 
 | |
|   * `reinstall` <formula>:
 | |
|     Uninstall then install <formula>
 | |
| 
 | |
|   * `rm`, `remove`, `uninstall [--force]` <formula>:
 | |
|     Uninstall <formula>.
 | |
| 
 | |
|     If `--force` is passed, and there are multiple versions of <formula>
 | |
|     installed, delete all installed versions.
 | |
| 
 | |
|   * `search`, `-S`:
 | |
|     Display all locally available formulae for brewing (including tapped ones).
 | |
|     No online search is performed if called without arguments.
 | |
| 
 | |
|   * `search`, `-S` <text>|/<text>/:
 | |
|     Perform a substring search of formula names for <text>. If <text> is
 | |
|     surrounded with slashes, then it is interpreted as a regular expression.
 | |
|     The search for <text> is extended online to some popular taps.
 | |
| 
 | |
|   * `search --debian`|`--fedora`|`--fink`|`--macports`|`--opensuse`|`--ubuntu` <text>:
 | |
|     Search for <text> in the given package manager's list.
 | |
| 
 | |
|   * `sh [--env=std]`:
 | |
|     Instantiate a Homebrew build environment. Uses our years-battle-hardened
 | |
|     Homebrew build logic to help your `./configure && make && make install`
 | |
|     or even your `gem install` succeed. Especially handy if you run Homebrew
 | |
|     in a Xcode-only configuration since it adds tools like make to your PATH
 | |
|     which otherwise build-systems would not find.
 | |
| 
 | |
|   * `switch` <name> <version>:
 | |
|     Symlink all of the specific <version> of <name>'s install to Homebrew prefix.
 | |
| 
 | |
|   * `tap` [--full] [<tap>]:
 | |
|     Tap a new formula repository from GitHub, or list existing taps.
 | |
| 
 | |
|     <tap> is of the form <user>/<repo>, e.g. `brew tap homebrew/dupes`.
 | |
| 
 | |
|     If `--full` is passed, a full clone will be used.
 | |
| 
 | |
|   * `tap --repair`:
 | |
|     Ensure all tapped formulae are symlinked into Library/Formula and prune dead
 | |
|     formulae from Library/Formula.
 | |
| 
 | |
|   * `test` [--devel|--HEAD] [--debug] <formula>:
 | |
|     A few formulae provide a test method. `brew test <formula>` runs this
 | |
|     test method. There is no standard output or return code, but it should
 | |
|     generally indicate to the user if something is wrong with the installed
 | |
|     formula.
 | |
| 
 | |
|     To test the development or head version of a formula, use `--devel` or
 | |
|     `--HEAD`.
 | |
| 
 | |
|     If `--debug` is passed and the test fails, an interactive debugger will be
 | |
|     launched with access to IRB or a shell inside the temporary test directory.
 | |
| 
 | |
|     Example: `brew install jruby && brew test jruby`
 | |
| 
 | |
|   * `unlink` <formula>:
 | |
|     Remove symlinks for <formula> from the Homebrew prefix. This can be useful
 | |
|     for temporarily disabling a formula:
 | |
|     `brew unlink foo && commands && brew link foo`.
 | |
| 
 | |
|   * `unlinkapps [--local]` [<formulae>]:
 | |
|     Removes links created by `brew linkapps`.
 | |
| 
 | |
|     If no <formulae> are provided, all linked app will be removed.
 | |
| 
 | |
|   * `unpack [--git|--patch] [--destdir=<path>]` <formulae>:
 | |
|     Unpack the source files for <formulae> into subdirectories of the current
 | |
|     working directory. If `--destdir=<path>` is given, the subdirectories will
 | |
|     be created in the directory named by `<path>` instead.
 | |
| 
 | |
|     If `--patch` is passed, patches for <formulae> will be applied to the
 | |
|     unpacked source.
 | |
| 
 | |
|     If `--git` is passed, a Git repository will be initalized in the unpacked
 | |
|     source. This is useful for creating patches for the software.
 | |
| 
 | |
|   * `unpin` <formulae>:
 | |
|     Unpin <formulae>, allowing them to be upgraded by `brew upgrade --all`. See also
 | |
|     `pin`.
 | |
| 
 | |
|   * `untap` <tap>:
 | |
|     Remove a tapped repository.
 | |
| 
 | |
|   * `update [--rebase]`:
 | |
|     Fetch the newest version of Homebrew and all formulae from GitHub using
 | |
|      `git`(1).
 | |
| 
 | |
|     If `--rebase` is specified then `git pull --rebase` is used.
 | |
| 
 | |
|   * `upgrade [--all] [install-options]` [<formulae>]:
 | |
|     Upgrade outdated, unpinned brews.
 | |
| 
 | |
|     Options for the `install` command are also valid here.
 | |
| 
 | |
|     If `--all` is passed, upgrade all formulae. This is currently the same
 | |
|     behaviour as without `--all` but soon `--all` will be required to upgrade
 | |
|     all formulae.
 | |
| 
 | |
|     If <formulae> are given, upgrade only the specified brews (but do so even
 | |
|     if they are pinned; see `pin`, `unpin`).
 | |
| 
 | |
|   * `uses [--installed] [--recursive] [--skip-build] [--skip-optional] [--devel|--HEAD]` <formulae>:
 | |
|     Show the formulae that specify <formulae> as a dependency. When given
 | |
|     multiple formula arguments, show the intersection of formulae that use
 | |
|     <formulae>.
 | |
| 
 | |
|     Use `--recursive` to resolve more than one level of dependencies.
 | |
| 
 | |
|     If `--installed` is passed, only list installed formulae.
 | |
| 
 | |
|     By default, `uses` shows all formulae that specify <formulae> as a dependency.
 | |
|     To skip the `:build` type dependencies, pass `--skip-build`. Similarly, pass
 | |
|     `--skip-optional` to skip `:optional` dependencies.
 | |
| 
 | |
|     By default, `uses` shows usages of `formula` by stable builds. To find
 | |
|     cases where `formula` is used by development or HEAD build, pass
 | |
|     `--devel` or `--HEAD`.
 | |
| 
 | |
|   * `--cache`:
 | |
|     Display Homebrew's download cache. See also `HOMEBREW_CACHE`.
 | |
| 
 | |
|   * `--cache` <formula>:
 | |
|     Display the file or directory used to cache <formula>.
 | |
| 
 | |
|   * `--cellar`:
 | |
|     Display Homebrew's Cellar path. *Default:* `/usr/local/Cellar`
 | |
| 
 | |
|   * `--cellar` <formula>:
 | |
|     Display the location in the cellar where <formula> would be installed,
 | |
|     without any sort of versioned directory as the last path.
 | |
| 
 | |
|   * `--env`:
 | |
|     Show a summary of the Homebrew build environment.
 | |
| 
 | |
|   * `--prefix`:
 | |
|     Display Homebrew's install path. *Default:* `/usr/local`
 | |
| 
 | |
|   * `--prefix` <formula>:
 | |
|     Display the location in the cellar where <formula> is or would be installed.
 | |
| 
 | |
|   * `--repository`:
 | |
|     Display where Homebrew's `.git` directory is located. For standard installs,
 | |
|     the `prefix` and `repository` are the same directory.
 | |
| 
 | |
|   * `--version`:
 | |
|     Print the version number of brew to standard error and exit.
 | |
| 
 | |
| ## EXTERNAL COMMANDS
 | |
| 
 | |
| Homebrew, like `git`(1), supports external commands. These are executable
 | |
| scripts that reside somewhere in the PATH, named `brew-<cmdname>` or
 | |
| `brew-<cmdname>.rb`, which can be invoked like `brew cmdname`. This allows you
 | |
| to create your own commands without modifying Homebrew's internals.
 | |
| 
 | |
| Instructions for creating your own commands can be found in the docs:
 | |
| <https://github.com/Homebrew/homebrew/blob/master/share/doc/homebrew/External-Commands.md>
 | |
| 
 | |
| ## SPECIFYING FORMULAE
 | |
| 
 | |
| Many Homebrew commands accept one or more <formula> arguments. These arguments
 | |
| can take several different forms:
 | |
| 
 | |
|   * The name of a formula:
 | |
|     e.g. `git`, `node`, `wget`.
 | |
| 
 | |
|   * The fully-qualified name of a tapped formula:
 | |
|     Sometimes a formula from a tapped repository may conflict with one in Homebrew/homebrew.
 | |
|     You can still access these formulae by using a special syntax, e.g.
 | |
|     `homebrew/dupes/vim` or `homebrew/versions/node4`.
 | |
| 
 | |
|   * An arbitrary URL:
 | |
|     Homebrew can install formulae via URL, e.g.
 | |
|     `https://raw.github.com/Homebrew/homebrew/master/Library/Formula/git.rb`.
 | |
|     The formula file will be cached for later use.
 | |
| 
 | |
| ## ENVIRONMENT
 | |
| 
 | |
|   * AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY:
 | |
|     When using the S3 download strategy, Homebrew will look in
 | |
|     these variables for access credentials (see
 | |
|     <https://docs.aws.amazon.com/cli/latest/userguide/cli-chap-getting-started.html#cli-environment>
 | |
|     to retrieve these access credentials from AWS).  If they are not set,
 | |
|     the S3 download strategy will download with a public
 | |
|     (unsigned) URL.
 | |
| 
 | |
|   * BROWSER:
 | |
|     If set, and `HOMEBREW_BROWSER` is not, use `BROWSER` as the web browser
 | |
|     when opening project homepages.
 | |
| 
 | |
|   * EDITOR:
 | |
|     If set, and `HOMEBREW_EDITOR` and `VISUAL` are not, use `EDITOR` as the text editor.
 | |
| 
 | |
|   * GIT:
 | |
|     When using Git, Homebrew will use `GIT` if set,
 | |
|     a Homebrew-built Git if installed, or the system-provided binary.
 | |
| 
 | |
|     Set this to force Homebrew to use a particular git binary.
 | |
| 
 | |
|   * HOMEBREW_BROWSER:
 | |
|     If set, uses this setting as the browser when opening project homepages,
 | |
|     instead of the OS default browser.
 | |
| 
 | |
|   * HOMEBREW\_BUILD\_FROM\_SOURCE:
 | |
|     If set, instructs Homebrew to compile from source even when a formula
 | |
|     provides a bottle.
 | |
| 
 | |
|   * HOMEBREW\_CACHE:
 | |
|     If set, instructs Homebrew to use the given directory as the download cache.
 | |
| 
 | |
|     *Default:* `~/Library/Caches/Homebrew` if it exists; otherwise,
 | |
|     `/Library/Caches/Homebrew`.
 | |
| 
 | |
|   * HOMEBREW\_CURL\_VERBOSE:
 | |
|     If set, Homebrew will pass `--verbose` when invoking `curl`(1).
 | |
| 
 | |
|   * HOMEBREW\_DEBUG:
 | |
|     If set, any commands that can emit debugging information will do so.
 | |
| 
 | |
|   * HOMEBREW\_DEBUG\_INSTALL:
 | |
|     When `brew install -d` or `brew install -i` drops into a shell,
 | |
|     `HOMEBREW_DEBUG_INSTALL` will be set to the name of the formula being
 | |
|     brewed.
 | |
| 
 | |
|   * HOMEBREW\_DEBUG\_PREFIX:
 | |
|     When `brew install -d` or `brew install -i` drops into a shell,
 | |
|     `HOMEBREW_DEBUG_PREFIX` will be set to the target prefix in the Cellar
 | |
|     of the formula being brewed.
 | |
| 
 | |
|   * HOMEBREW\_DEVELOPER:
 | |
|     If set, Homebrew will print warnings that are only relevant to Homebrew
 | |
|     developers (active or budding).
 | |
| 
 | |
|   * HOMEBREW\_EDITOR:
 | |
|     If set, Homebrew will use this editor when editing a single formula, or
 | |
|     several formulae in the same directory.
 | |
| 
 | |
|     *NOTE*: `brew edit` will open all of Homebrew as discontinuous files and
 | |
|     directories. TextMate can handle this correctly in project mode, but many
 | |
|     editors will do strange things in this case.
 | |
| 
 | |
|   * HOMEBREW\_GITHUB\_API\_TOKEN:
 | |
|     A personal access token for the GitHub API, which you can create at
 | |
|     <https://github.com/settings/tokens>. If set, GitHub will allow you a
 | |
|     greater number of API requests. See
 | |
|     <https://developer.github.com/v3/#rate-limiting> for more information.
 | |
|     Homebrew uses the GitHub API for features such as `brew search`.
 | |
| 
 | |
|   * HOMEBREW\_LOGS:
 | |
|     If set, Homebrew will use the given directory to store log files.
 | |
| 
 | |
|   * HOMEBREW\_MAKE\_JOBS:
 | |
|     If set, instructs Homebrew to use the value of `HOMEBREW_MAKE_JOBS` as
 | |
|     the number of parallel jobs to run when building with `make`(1).
 | |
| 
 | |
|     *Default:* the number of available CPU cores.
 | |
| 
 | |
|   * HOMEBREW\_NO\_EMOJI:
 | |
|     If set, Homebrew will not print the `HOMEBREW_INSTALL_BADGE` on a
 | |
|     successful build.
 | |
| 
 | |
|     *Note:* Homebrew will only try to print emoji on Lion or newer.
 | |
| 
 | |
|   * HOMEBREW\_NO\_GITHUB\_API:
 | |
|     If set, Homebrew will not use the GitHub API for e.g searches or
 | |
|     fetching relevant issues on a failed install.
 | |
| 
 | |
|   * HOMEBREW\_INSTALL\_BADGE:
 | |
|     Text printed before the installation summary of each successful build.
 | |
|     Defaults to the beer emoji.
 | |
| 
 | |
|   * HOMEBREW\_SVN:
 | |
|     When exporting from Subversion, Homebrew will use `HOMEBREW_SVN` if set,
 | |
|     a Homebrew-built Subversion if installed, or the system-provided binary.
 | |
| 
 | |
|     Set this to force Homebrew to use a particular svn binary.
 | |
| 
 | |
|   * HOMEBREW\_TEMP:
 | |
|     If set, instructs Homebrew to use `HOMEBREW_TEMP` as the temporary directory
 | |
|     for building packages. This may be needed if your system temp directory and
 | |
|     Homebrew Prefix are on different volumes, as OS X has trouble moving
 | |
|     symlinks across volumes when the target does not yet exist.
 | |
| 
 | |
|     This issue typically occurs when using FileVault or custom SSD
 | |
|     configurations.
 | |
| 
 | |
|   * HOMEBREW\_VERBOSE:
 | |
|     If set, Homebrew always assumes `--verbose` when running commands.
 | |
| 
 | |
|   * VISUAL:
 | |
|     If set, and `HOMEBREW_EDITOR` is not, use `VISUAL` as the text editor.
 | |
| 
 | |
| ## USING HOMEBREW BEHIND A PROXY
 | |
| 
 | |
| Homebrew uses several commands for downloading files (e.g. curl, git, svn).
 | |
| Many of these tools can download via a proxy. It's common for these tools
 | |
| to read proxy parameters from environment variables.
 | |
| 
 | |
| For the majority of cases setting `http_proxy` is enough. You can set this in
 | |
| your shell profile, or you can use it before a brew command:
 | |
| 
 | |
|     http_proxy=http://<host>:<port> brew install foo
 | |
| 
 | |
| If your proxy requires authentication:
 | |
| 
 | |
|     http_proxy=http://<user>:<password>@<host>:<port> brew install foo
 | |
