![]() If we conditionally "declare" the argument, as we did before, based upon weather the feature is enabled, commands like nix --experimental-features=foo ... --thing-gated-on-foo won't work, because the experimental feature isn't enabled until *after* we start parsing. Instead, allow arguments to also be associated with experimental features (just as we did for builtins and settings), and then the command line parser will filter out the experimental ones. Since the effects of arguments (handler functions) are performed right away, we get the required behavior: earlier arguments can enable later arguments enabled! There is just one catch: we want to keep non-positional flags...non-positional. So if nix --experimental-features=foo ... --thing-gated-on-foo works, then nix --thing-gated-on-foo --experimental-features=foo ... should also work. This is not my favorite long-term solution, but for now this is implemented by delaying the requirement of needed experimental features until *after* all the arguments have been parsed. |
