The platform this gem works on.
Installs this specification using the Gem::Installer options. The install method yields a Gem::Installer instance, which indicates the gem will be installed, or nil, which indicates the gem is already installed.
After installation spec is updated to point to the just-installed specification.
This is a null install as this gem was unpacked into a directory. options are ignored.
Returns the file name of this frame. This will generally be an absolute path, unless the frame is in the main script, in which case it will be the script location passed on the command line.
For example, using caller_locations.rb from Thread::Backtrace::Location
loc = c(0..1).first loc.path #=> caller_locations.rb
This method verifies that there are no (obvious) ambiguities with the provided col_sep and strip parsing options. For example, if col_sep and strip were both equal to \t, then there would be no clear way to parse the input.

Returns a new lazy enumerator with the concatenated results of running block once for every element in the lazy enumerator.
["foo", "bar"].lazy.flat_map {|i| i.each_char.lazy}.force #=> ["f", "o", "o", "b", "a", "r"]
A value x returned by block is decomposed if either of the following conditions is true:
x responds to both each and force, which means that x is a lazy enumerator.
x is an array or responds to to_ary.
Otherwise, x is contained as-is in the return value.
[{a:1}, {b:2}].lazy.flat_map {|i| i}.force
#=> [{:a=>1}, {:b=>2}]

Like Enumerable#take_while, but chains operation to be lazy-evaluated.
