Is there any way to force fish to perform parameter expansion on a variable? That is, if a variable is equal to "*.txt", how can that be expanded to "bar.txt baz.txt" or "" or whatever it actually matches?
The motivation for this is so that it's possible to write a function "append_to_path_if_exists" that appends its argument to fish_user_paths if and only if the argument actually exists as a directory. So I want to be able to do: append_to_path_if_exists "/Applications/ghc-*.app/Contents/bin" append_to_path_if_exists "~/.gem/ruby/*/bin" append_to_path_if_exists "/usr/lib/go-*/bin" Without the quotes, fish (now) whines if these directories don't exist, but with the quotes, I can't figure out a good way to actually expand the argument within the append_to_path_if_exists function. This is sort of possible via a subshell, but it's hardly ideal: function glob echo (fish -c "count $argv > /dev/null ; and echo $argv") end $ glob "*.txt" bar.txt baz.txt $ glob "jjj*" (Also doesn't work with multiple arguments.) Am I going about this the wrong way? Michael ------------------------------------------------------------------------------ What NetFlow Analyzer can do for you?
