# The ruby_exe helper provides a wrapper for invoking the
# same Ruby interpreter with the same falgs as the one running
# same Ruby interpreter with the same flags as the one running
# the specs and getting the output from running the code.
#
# If +code+ is a file that exists, it will be run.
# Otherwise, +code+ should be Ruby code that will be run with
# the -e command line option. For example:
# Otherwise, +code+ will be written to a temporary file and be run.

# ruby_exe('path/to/some/file.rb')

# The RUBY_EXE constant is setup by mspec automatically
# and is used by ruby_exe and ruby_cmd. The mspec runner script
# will set ENV['RUBY_EXE'] to the name of the executable used
# to invoke the mspec-run script. The value of RUBY_EXE will be
# constructed as follows:
#
# 1. the value of ENV['RUBY_EXE']
# 2. an explicit value based on RUBY_ENGINE
# 3. cwd/(RUBY_ENGINE + $(EXEEXT) || $(exeext) || '')
# 4. $(bindir)/$(RUBY_INSTALL_NAME)
# to invoke the mspec-run script.
#
# The value will only be used if the file exists and is executable.
# The flags will then be appended to the resulting value.
#
# These 4 ways correspond to the following scenarios:
#
# 1. Using the MSpec runner scripts, the name of the
# executable is explicitly passed by ENV['RUBY_EXE']
# so there is no ambiguity.
#
# Otherwise, if using RSpec (or something else)
#
# 2. Running the specs while developing an alternative
# Ruby implementation. This explicitly names the
# executable in the development directory based on
# the value of RUBY_ENGINE.
# 3. Running the specs within the source directory for
# some implementation. (E.g. a local build directory.)
# 4. Running the specs against some installed Ruby
# implementation.
# The flags will then be appended to the resulting value, such that
# the RUBY_EXE constant contains both the executable and the flags.
#
# Additionally, the flags passed to mspec
# (with -T on the command line or in the config with set :flags)
