> $m/inst/stow/ I just want to cd there! It's no different from, say, ~/inst/stow/ which means the same thing as $HOME/inst/stow/ ! Tab completion even works! And I get: fish: Variables may not be used as commands. Instead, define a function. See the help section for the function command by typing “help function”.
I'm just going to patch fish to allow variables in commands (assuming it's simple enough), for my own use; I'll send the patch in case you feel like applying it. Do note however that for programming -- not for convenient use -- there is a fairly easy solution that packages up the eval/function hackery (eval is at a great cost -- fish builtins/functions may be accidentally called, so you may actually not want to do this in a script) : alias foo $dollars/using/expression foo If we wanted we could define function run alias -l foo $argv[1] shift #wrong foo $argv end ... except that there's no -l for alias so we're stuck with inlining its definitions... oh wait... there isn't even a -l for functions, and no lambda functions, they all have a global name! And except that I couldn't find a way in fish's documentation to take a section of an array or in any way do something equivalent to bash's `shift` to get $argv[2..infinity] I think it's plausible that: $-in-command = warning in scripts = run = eval-ish run = eval-ish (not at all equivalent to eval though, remember) = function or builtin or command or cd, in approximately that order. And that's the problem, too, with using eval to implement it: the "command" could contain an evil string like 'begin;'. However, I think we might be able to implement it as a function, using `type -t`. Remember shells are not a macro expansion language! command = you know = env cd = you know builtin = you know function = er, is this possible? Probably to use "run" instead. Then (modulo one warning perhaps) we could define function run; $argv; end Maybe this will even be able to allow `run function --help` ;-) -Isaac ------------------------------------------------------------------------- Sponsored by: SourceForge.net Community Choice Awards: VOTE NOW!
