# Note [Replacing backward slashes in config.libdir]
# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
#
# We *do* need to replace backslashes in config.libdir, for the following
# reason:
#
# * Tests use config.libdir as follows:
#
#     extra_run_opts('"' + config.libdir + '"')
#
#   The double quotes are there because config.libdir might contain
#   spaces.
#
# * This string is then written /as is/ to <testname>.genscript in
#   testlib.interpreter_run:
#
#     script.write(':set args ' + opts.extra_run_opts + '\n')
#
# * But GHCi expects the arguments to ':set args' to be proper Haskell
#   strings (when they are quoted), with backslashes escaped. Since
#   config.libdir contains single backslash characters, tests such as T5313
#   will fail for WAY=ghci with "Pattern match failure in do expression".
#
# Arguably the above code for writing `:set args` should be smarter. This
# is tricky to get right though, because in GHCI `:set args foo\bar` (no
# double quotes) works perfectly fine, and is interpreted as the Haskell
# string "foo\\bar". Therefore, simply escaping all backward slashes in
# opts.extra_run_opts before concatenating it with ':set args' is not right
# either.
#
# Replacing backslashes to forward slashes in config.libdir works around the
# problem.
