* Upgrade operation in `nix-env'. For instance, you can say
nix-env -u foo.nix strategoxt to replace the installed `strategoxt' derivation with the one from `foo.nix', if the latter has a higher version number. This is a no-op if `strategoxt' is not installed. Wildcards are also accepted, so nix-env -u foo.nix '*' will replace any installed derivation with newer versions from `foo.nix', if available. The notion of "version number" is somewhat ad hoc, but should be useful in most cases, as evidenced by the following unit tests for the version comparator: TEST("1.0", "2.3", -1); TEST("2.1", "2.3", -1); TEST("2.3", "2.3", 0); TEST("2.5", "2.3", 1); TEST("3.1", "2.3", 1); TEST("2.3.1", "2.3", 1); TEST("2.3.1", "2.3a", 1); TEST("2.3pre1", "2.3", -1); TEST("2.3pre3", "2.3pre12", -1); TEST("2.3a", "2.3c", -1); TEST("2.3pre1", "2.3c", -1); TEST("2.3pre1", "2.3q", -1); (-1 = less, 0 = equal, 1 = greater) * A new verbosity level `lvlInfo', between `lvlError' and `lvlTalkative'. This is the default for `nix-env', so without any `-v' flags users should get useful output, e.g., $ nix-env -u foo.nix strategoxt upgrading `strategoxt-0.9.2' to `strategoxt-0.9.3'
