Public Instance Methods
@return [Pod::Version] the version of CocoaPods currently running
# File lib/pod/command/try.rb, line 272 def cocoapods_version Pod::Version.new(Pod::VERSION) end
@return [Bool] Wether the given string is the name of a Pod
or an URL
for a Git repo.
# File lib/pod/command/try.rb, line 251 def git_url?(name) prefixes = ['https://', 'http://'] prefixes.any? { |prefix| name.start_with?(prefix) } end
Installs the specification in the given directory.
@param [Specification] The specification of the Pod
. @param [Pathname] The directory of the sandbox where to install the
Pod.
@return [Pathname] The path where the Pod
was installed

Performs a CocoaPods installation for the given project if Podfile is found. Shells out to avoid issues with the config of the process running the try command.
@return [String] proj
The path of the project.
@return [String] The path of the file to open, in other words the
workspace of the installation or the given project.

Opens the project at the given path.
@return [String] path
The path of the project.
@return [void]

@return [void] Performs a CocoaPods installation in the working
directory.

Picks a project or workspace suitable for the demo purposes in the given directory.
To decide the project simple heuristics are used according to the name, if no project is found this method raises and `Informative` otherwise if more than one project is found the choice is presented to the user.
@param [#to_s] dir
The path where to look for projects.
@return [String] The path of the project.
