2016-02-12	Merge pull request #762 from ctheune/ctheune-floats	Eelco Dolstra	1	-7/+34
	Implement floats
2016-02-04	Eliminate the "store" global variable	Eelco Dolstra	1	-29/+28
	Also, move a few free-standing functions into StoreAPI and Derivation. Also, introduce a non-nullable smart pointer, ref<T>, which is just a wrapper around std::shared_ptr ensuring that the pointer is never null. (For reference-counted values, this is better than passing a "T&", because the latter doesn't maintain the refcount. Usually, the caller will have a shared_ptr keeping the value alive, but that's not always the case, e.g., when passing a reference to a std::thread via std::bind.)
2016-01-07	Fix some signedness warnings	Eelco Dolstra	1	-1/+1

2016-01-05	Better error message	Fabian Schmitthenner	1	-1/+1
	Also show types when nix cannot compare values of different types. This is also more consistent since types are already shown when comparing values of the same not comparable type.
2016-01-05	manual: document builtins.functionArgs	Vladimír Čunát	1	-1/+1
	The text is just a conversion of comment from src/libexpr/primops.cc
2016-01-05	First hit at providing support for floats in the language.	Christian Theune	1	-7/+34

2015-07-28	Add sort primop	Eelco Dolstra	1	-1/+36

2015-07-28	Add primop genList	Eelco Dolstra	1	-0/+20
	This can be used to implement functions like ‘imap’ (or for that matter, ‘map’) without the quadratic complexity incurred by calling ‘++’ repeatedly.
2015-07-24	Add replaceStrings primop	Eelco Dolstra	1	-1/+37
	This is a generalisation of replaceChars in Nixpkgs.
2015-07-24	Add concatStringsSep as a primop	Eelco Dolstra	1	-0/+21
	This fixes the quadratic behaviour of concatStrings/concatStringsSep in Nixpkgs.
2015-07-23	Optimize small lists	Eelco Dolstra	1	-58/+58
	The value pointers of lists with 1 or 2 elements are now stored in the list value itself. In particular, this makes the "concatMap (x: if cond then [(f x)] else [])" idiom cheaper.
2015-07-23	Add primops all and any	Eelco Dolstra	1	-0/+33
	These are used thousands of times during NixOS evaluation, so it's useful to speed them up.
2015-07-23	Importing derivations: Add name attribute to make a valid drv	Shea Levy	1	-1/+3

2015-07-23	Allow derivations-as-srcs in the context of builtins.toFile files	Shea Levy	1	-2/+6

2015-07-23	Add foldl' primop	Eelco Dolstra	1	-0/+24

2015-07-17	OCD: foreach -> C++11 ranged for	Eelco Dolstra	1	-50/+45

2015-06-01	Fix fetchurl/fetchTarball	Eelco Dolstra	1	-1/+2

2015-06-01	readFile: Check against nul bytes	Eelco Dolstra	1	-1/+4

2015-05-05	Allow URLs in the Nix search path	Eelco Dolstra	1	-85/+3
	E.g. to install "hello" from the latest Nixpkgs: $ nix-build '<nixpkgs>' -A hello -I nixpkgs=https://nixos.org/channels/nixpkgs-unstable/nixexprs.tar.xz Or to install a specific version of NixOS: $ nixos-rebuild switch -I nixpkgs=https://github.com/NixOS/nixpkgs/archive/63def04891a0abc328b1b0b3a78ec02c58f48583.tar.gz
2015-04-09	Use cached result if there is a network error	Eelco Dolstra	1	-7/+12

2015-04-09	Move curl stuff into a separate file	Eelco Dolstra	1	-112/+6

2015-04-09	Implement a TTL on cached fetchurl/fetchTarball results	Eelco Dolstra	1	-13/+24
	This is because we don't want to do HTTP requests on every evaluation, even though we can prevent a full redownload via the cached ETag. The default is one hour.
2015-04-09	Implement caching of fetchurl/fetchTarball results	Eelco Dolstra	1	-14/+119
	ETags are used to prevent redownloading unchanged files.
2015-03-25	Add fetchTarball builtin	Eelco Dolstra	1	-0/+119
	This function downloads and unpacks the given URL at evaluation time. This is primarily intended to make it easier to deal with Nix expressions that have external dependencies. For instance, to fetch Nixpkgs 14.12: with import (fetchTarball https://github.com/NixOS/nixpkgs-channels/archive/nixos-14.12.tar.gz) {}; Or to fetch a specific revision: with import (fetchTarball https://github.com/NixOS/nixpkgs/archive/2766a4b44ee6eafae03a042801270c7f6b8ed32a.tar.gz) {}; This patch also adds a ‘fetchurl’ builtin that downloads but doesn't unpack its argument. Not sure if it's useful though.
2015-03-25	addToStore(): Take explicit name argument	Eelco Dolstra	1	-1/+1

2015-03-24	Don't rely on __noChroot for corepkgs	Eelco Dolstra	1	-2/+5
	This doesn't work anymore if the "strict" chroot mode is enabled. Instead, add Nix's store path as a dependency. This ensures that its closure is present in the chroot.
2015-03-06	Fix typos: s/the the/the/	Daniel Hahler	1	-1/+1

2015-02-23	Add restricted evaluation mode	Eelco Dolstra	1	-7/+21
	If ‘--option restrict-eval true’ is given, the evaluator will throw an exception if an attempt is made to access any file outside of the Nix search path. This is primarily intended for Hydra, where we don't want people doing ‘builtins.readFile ~/.ssh/id_dsa’ or stuff like that.
2015-02-05	Remove tab	Eelco Dolstra	1	-1/+1

2015-01-29	Merge remote-tracking branch 'shlevy/baseNameOf-no-copy'	Shea Levy	1	-1/+1
	baseNameOf: Don't copy paths to the store first
2015-01-09	Fix builtins.readDir on XFS	Eelco Dolstra	1	-1/+1
	The DT_UNKNOWN fallback code was getting the type of the wrong path, causing readDir to report "directory" as the type of every file. Reported by deepfire on IRC.
2015-01-07	Show position info for failing <...> lookups	Eelco Dolstra	1	-1/+1

2014-12-12	Remove canary stuff	Eelco Dolstra	1	-27/+0

2014-12-10	builtins.readFile: realise context associated with the path	Shea Levy	1	-2/+6

2014-12-02	Allow external code using libnixexpr to add types	Shea Levy	1	-0/+3
	Code that links to libnixexpr (e.g. plugins loaded with importNative, or nix-exec) may want to provide custom value types and operations on values of those types. For example, nix-exec is currently using sets where a custom IO value type would be more appropriate. This commit provides a generic hook for such types in the form of tExternal and the ExternalBase virtual class, which contains all functions necessary for libnixexpr's type-polymorphic functions (e.g. `showType`) to be implemented.
2014-11-25	Add a primop for regular expression pattern matching	Eelco Dolstra	1	-1/+29
	The function ‘builtins.match’ takes a POSIX extended regular expression and an arbitrary string. It returns ‘null’ if the string does not match the regular expression. Otherwise, it returns a list containing substring matches corresponding to parenthesis groups in the regex. The regex must match the entire string (i.e. there is an implied "^<pat>$" around the regex). For example: match "foo" "foobar" => null match "foo" "foo" => [] match "f(o+)(.)" "foooobar" => ["oooo" "bar"] match "(./)?([^/])" "/dir/file.nix" => ["/dir/" "file.nix"] match "(./)?([^/])" "file.nix" => [null "file.nix"] The following example finds all regular files with extension .nix or .patch underneath the current directory: let findFiles = pat: dir: concatLists (mapAttrsToList (name: type: if type == "directory" then findFiles pat (dir + "/" + name) else if type == "regular" && match pat name != null then [(dir + "/" + name)] else []) (readDir dir)); in findFiles ".\\.(nix\|patch)" (toString ./.)
2014-11-25	forceString(): Accept pos argument	Eelco Dolstra	1	-2/+2

2014-11-20	import derivation: cleanup	Shea Levy	1	-8/+11
	Before this there was a bug where a `find` was being called on a not-yet-sorted set. The code was just a mess before anyway, so I cleaned it up while fixing it.
2014-11-15	realiseContext: Handle all context types	Shea Levy	1	-2/+2
	Avoids an assertion
2014-10-18	baseNameOf: Don't copy paths to the store first	Shea Levy	1	-1/+1

2014-10-17	Export realiseContext in libnixexpr	Shea Levy	1	-9/+3
	Useful for importNative plugins
2014-10-04	Add primop ‘catAttrs’	Eelco Dolstra	1	-0/+30

2014-10-04	Add primop ‘attrValues’	Eelco Dolstra	1	-1/+23

2014-10-04	Tweak	Eelco Dolstra	1	-1/+1

2014-10-03	Remove some duplicate code	Eelco Dolstra	1	-15/+8

2014-10-03	Add readDir primop	Shea Levy	1	-0/+37

2014-09-23	Add missing static	Eelco Dolstra	1	-2/+2

2014-09-22	Don't evaluate inside a "throw"	Eelco Dolstra	1	-3/+4
	Workaround for https://gcc.gnu.org/bugzilla/show_bug.cgi?id=41174. This caused hydra-eval-jobs to ignore SIGINT.
2014-09-22	Add ‘deepSeq’ primop	Eelco Dolstra	1	-0/+11
	Note that unlike ‘lib.deepSeq’ in Nixpkgs, this handles cycles.
2014-09-22	Add ‘seq’ primop	Eelco Dolstra	1	-0/+12
