# DSL. Each method should handle output, following the convention of

|
# at least one trailing blank line so that the user can distinguish

# separate caveats.

# ( The return value of the last method in the block is also sent

# to the output by the caller, but that feature is only for the

To use #{@cask}, you may need to add the #{path} directory
|
|
to your PATH environment variable, eg (for bash shell):
|
|
|
|
export PATH=#{path}:"$PATH"
|
|
|
|
EOS

end
|
|

|
def zsh_path_helper(path)
|
|
puts <<-EOS.undent
|
|
To use #{@cask}, zsh users may need to add the following line to their
|
|
~/.zprofile. (Among other effects, #{path} will be added to the
|
|
PATH environment variable):
|
|
|
|
eval `/usr/libexec/path_helper -s`
|
|
|
|
EOS

|
|
if Hbc.homebrew_prefix.to_s.downcase.index(localpath) == 0
|
|
puts <<-EOS.undent
|
|
Cask #{@cask} installs files under "#{localpath}". The presence of such
|
|
files can cause warnings when running "brew doctor", which is considered
|
|
to be a bug in homebrew-cask.
