# Provide a minimalist realpath implementation to help deal with platforms that may not provide it # as a command. If a realpath command is available simply pass all arguments thru to it. If not # fallback to alternative solutions. # The following is slightly subtle. The first time `realpath` is invoked this script will be read. # If we see that there is an external command by that name we just return. That will cause fish to # run the external command. On the other hand, if an external command isn't found we define a # function that will provide fallback behavior. if not type -q -P realpath function realpath --description 'fallback realpath implementation' builtin fish_realpath $argv[-1] end end
