Eelco Dolstra	d567baabbd	* Export the nix-env derivation name parsing and version comparison ... logic through the `parseDrvName' and `compareVersions' primops. This will allow expressions to easily check whether some dependency is a specific needed version or falls in some version range. See tests/lang/eval-okay-versions.nix for examples.	2008-07-01 10:10:32 +00:00

Eelco Dolstra	618aa69b01	* In --upgrade': added flags --lt', --leq', --always' to specify ... whether we want to upgrade if the current version is less than the available version (default), when it is less or equal, or always. * Added a flag `--dry-run' to show what would happen in `--install', `--uninstall', and `--upgrade', without actually performing the operation.	2004-02-09 11:59:39 +00:00
