module Sprinkle
module Verifiers
# = Executable Verifier
#
# Contains a verifier to check the existance of an executable
# script on your server.
#
# == Example Usage
#
# First, absolute path to an executable:
#
# verify { has_executable '/usr/special/secret/bin/scipt' }
#
# Second, a global executable which would be available anywhere on the
# command line:
#
# verify { has_executable 'grep' }
module Executable
Sprinkle::Verify.register(Sprinkle::Verifiers::Executable)
# Checks if <tt>path</tt> is an executable script. This verifier is "smart" because
# if the path contains a forward slash '/' then it assumes you're checking an
# absolute path to an executable. If no '/' is in the path, it assumes you're
# checking for a global executable that would be available anywhere on the command line.
def has_executable(path)
# Be smart: If the path includes a forward slash, we're checking
# an absolute path. Otherwise, we're checking a global executable
if path.include?('/')
@commands << "test -x #{path}"
else
@commands << "[ -n \"`echo \\`which #{path}\\``\" ]"
