case name.downcase
when "gem", /^rubygems?$/ then <<-EOS.undent
Homebrew provides gem via: `brew install ruby`.
EOS
when "tex", "tex-live", "texlive", "latex" then <<-EOS.undent
Installing TeX from source is weird and gross, requires a lot of patches,
and only builds 32-bit (and thus can't use Homebrew dependencies)
We recommend using a MacTeX distribution: https://www.tug.org/mactex/
You can install it with Homebrew-Cask:
brew cask install mactex
EOS
when "pip" then <<-EOS.undent
Homebrew provides pip via: `brew install python`. However you will then
have two Pythons installed on your Mac, so alternatively you can install
pip via the instructions at:
#{Formatter.url("https://pip.readthedocs.io/en/stable/installing/")}
EOS
when "pil" then <<-EOS.undent
Instead of PIL, consider `pip install pillow` or `brew install Homebrew/python/pillow`.
EOS
when "macruby" then <<-EOS.undent
MacRuby is not packaged and is on an indefinite development hiatus.
You can read more about it at:
#{Formatter.url("https://github.com/MacRuby/MacRuby")}
EOS
when /(lib)?lzma/
"lzma is now part of the xz formula."
when "gtest", "googletest", "google-test" then <<-EOS.undent
Installing gtest system-wide is not recommended; it should be vendored
in your projects that use it.
EOS
when "gmock", "googlemock", "google-mock" then <<-EOS.undent
Installing gmock system-wide is not recommended; it should be vendored
in your projects that use it.
EOS
when "sshpass" then <<-EOS.undent
We won't add sshpass because it makes it too easy for novice SSH users to
ruin SSH's security.
EOS
when "gsutil" then <<-EOS.undent
Install gsutil with `pip install gsutil`
EOS
when "clojure" then <<-EOS.undent
Clojure isn't really a program but a library managed as part of a
project and Leiningen is the user interface to that library.
To install Clojure you should install Leiningen:
brew install leiningen
and then follow the tutorial:
#{Formatter.url("https://github.com/technomancy/leiningen/blob/stable/doc/TUTORIAL.md")}
EOS
when "osmium" then <<-EOS.undent
The creator of Osmium requests that it not be packaged and that people
use the GitHub master branch instead.
EOS
when "gfortran" then <<-EOS.undent
GNU Fortran is now provided as part of GCC, and can be installed with:
brew install gcc
EOS
when "play" then <<-EOS.undent
Play 2.3 replaces the play command with activator:
brew install typesafe-activator
You can read more about this change at:
#{Formatter.url("https://www.playframework.com/documentation/2.3.x/Migration23")}
#{Formatter.url("https://www.playframework.com/documentation/2.3.x/Highlights23")}
EOS
when "haskell-platform" then <<-EOS.undent
We no longer package haskell-platform. Consider installing ghc
and cabal-install instead:
brew install ghc cabal-install
You can install with Homebrew-Cask:
brew cask install haskell-platform
EOS
when "mysqldump-secure" then <<-EOS.undent
The creator of mysqldump-secure tried to game our popularity metrics.
EOS
when "ngrok" then <<-EOS.undent
Upstream sunsetted 1.x in March 2016 and 2.x is not open-source.
If you wish to use the 2.x release you can install with Homebrew-Cask:
brew cask install ngrok
EOS

#{name} was deleted from #{tap.name} in commit #{short_hash}:
#{commit_message}
To show the formula before removal run:
git -C "$(brew --repo #{tap})" show #{short_hash}^:#{relative_path}
If you still use this formula consider creating your own tap:
