Eelco Dolstra	2c39e4eca0	Revert "Don't parse "x:x" as a URI" ... This reverts commit f90f660b24. This broke Hydra's release.nix, which contained preCheck = ''export LOGNAME=${LOGNAME:-foo}'';	2017-11-14 15:10:52 +01:00
Eelco Dolstra	f90f660b24	Don't parse "x:x" as a URI ... URIs now have to contain "://" or start with "channel:".	2017-10-30 17:58:01 +01:00
Eelco Dolstra	50807f3dd5	Add primop genList ... This can be used to implement functions like ‘imap’ (or for that matter, ‘map’) without the quadratic complexity incurred by calling ‘++’ repeatedly.	2015-07-28 17:28:35 +02:00
Eelco Dolstra	61af14a921	Add foldl' primop	2015-07-23 17:03:02 +02:00
Eelco Dolstra	5ad263c26b	Test some more primops	2014-02-26 19:08:44 +01:00
Eelco Dolstra	47701677e8	Add integer ‘-’, ‘*’ and ‘/’ operators	2013-08-02 16:03:02 +00:00
Eelco Dolstra	7cd88b1dec	* Generalised the dependencyClosure primop to builtins.genericClosure, ... which is hopefully more useful. * New primops: length, mul, div.	2008-07-11 13:29:04 +00:00
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	7349bd0176	New primitives: ... * `sub' to subtract two numbers. * `stringLength' to get the length of a string. * `substring' to get a substring of a string. These should be enough to allow most string operations to be expressed.	2007-01-29 14:23:09 +00:00
Eelco Dolstra	2ab4bc44c7	* Builtin function `add' to add integers. ... * Put common test functions in tests/lang/lib.nix.	2006-09-22 15:29:21 +00:00
