2008-02-05	* Doh.	Eelco Dolstra	1	-1/+1

2008-02-05	* Regression test.	Eelco Dolstra	2	-2/+9

2008-01-04	* New primop `unsafeDiscardStringContext' to get rid of string	Eelco Dolstra	2	-0/+7
	contexts. Needed to prevent unnecessary dependencies when building the NixOS manual.
2007-12-06	* Syntax to escape '', ${.	Eelco Dolstra	2	-2/+8

2007-11-30	* Added a new kind of multi-line string literal delimited by two	Eelco Dolstra	2	-0/+108
	single quotes. Example (from NixOS): job = '' start on network-interfaces start script rm -f /var/run/opengl-driver ${if videoDriver == "nvidia" then "ln -sf ${nvidiaDrivers} /var/run/opengl-driver" else if cfg.driSupport then "ln -sf ${mesa} /var/run/opengl-driver" else "" } rm -f /var/log/slim.log end script ''; This style has two big advantages: - \, ' and " aren't special, only '' and ${. So you get a lot less escaping in shell scripts / configuration files in Nixpkgs/NixOS. The delimiter '' is rare in scripts (and can usually be written as ""). ${ is also fairly rare. Other delimiters such as <<...>>, {{...}} and <\|...\|> were also considered but this one appears to have the fewest drawbacks (thanks Martin). - Indentation is intelligently stripped so that multi-line strings can follow the nesting structure of the containing Nix expression. E.g. in the example above 6 spaces are stripped from the start of each line. This prevents unnecessary indentation in generated files (which sometimes even breaks things). See tests/lang/eval-okay-ind-string.nix for some examples.
2007-11-21	* New primop `readFile' to get the contents of a file as a string.	Eelco Dolstra	2	-0/+2

2007-08-18	primop functions listToAttrs (+test), __isAttrs, __trace added	Marc Weber	2	-0/+9
	new configuration style proposal in lib/default-unstable.nix
2007-05-15	* Allow empty argument lists in function definitions (e.g., `{}:	Eelco Dolstra	2	-0/+2
	bla'). Also allow trailing commas (`{x, y,}: ...') as a unintented consequence. Hopefully the reduce/reduce conflict won't cause any problems.
2007-01-29	New primitives:	Eelco Dolstra	4	-3/+32
	* `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.
2007-01-14	* Option --argstr for passing string arguments easily. (NIX-75)	Eelco Dolstra	3	-0/+17

2007-01-13	* Canonicalise ASTs in `nix-instantiate --eval': remove position	Eelco Dolstra	4	-4/+4
	info, sort attribute sets.
2006-12-12	* New built-in function `builtins.attrNames' that returns the	Eelco Dolstra	2	-0/+12
	names of the attributes in an attribute set.
2006-10-17	* Another test.	Eelco Dolstra	1	-0/+1

2006-10-17	* Fix the tests wrt the AST changes, i.e., Str(s) -> Str(s, []), and	Eelco Dolstra	18	-18/+20
	the semantic changes.
2006-10-11	* Removed URIs from the evaluator (NIX-66). They are now just another	Eelco Dolstra	3	-3/+3
	kind of notation for strings.
2006-10-02	* Finally, a real "let" syntax: `let x = ...; ... z = ...; in ...'.	Eelco Dolstra	2	-0/+15

2006-09-24	* Primop `toPath' to convert a string to a path.	Eelco Dolstra	2	-0/+4
	* Primop `pathExists' to check for path existence.
2006-09-24	* Builtin function `getEnv' for getting environment variables.	Eelco Dolstra	2	-0/+2

2006-09-24	* lessThan primitive for integer comparison.	Eelco Dolstra	1	-1/+4

2006-09-22	* Builtin function `add' to add integers.	Eelco Dolstra	7	-23/+45
	* Put common test functions in tests/lang/lib.nix.
2006-09-22	* Added a builtin function `isList' to test whether a value is a list.	Eelco Dolstra	2	-0/+20
	With this primitive, a list-flattening function can be implemented (NIX-55, example is in tests/lang/eval-okay-flatten.nix).
2006-09-22	* Builtin functions `head' and `tail' to return the head and tail of	Eelco Dolstra	2	-0/+14
	list. Useful for lots of things, such as implementing a fold function (see NIX-30, example is in tests/lang/eval-okay-list.nix).
2006-09-22	* New builtin functions builtins.{hasAttr, getAttr} to check for	Eelco Dolstra	2	-0/+11
	attribute existence and to return an attribute from an attribute set, respectively. Example: `hasAttr "foo" {foo = 1;}'. They differ from the `?' and `.' operators in that the attribute name is an arbitrary expression. (NIX-61)
2006-09-01	* Allow "$" in strings as long as they are not followed by "{". (Too	Eelco Dolstra	2	-1/+2
	bad flex doesn't have lexical restrictions, the current solution isn't quite right...)
2006-08-30	* Okay, that's a bit harder than expected.	Eelco Dolstra	1	-0/+0

2006-08-30	* TDD: == should do a deep equality test, i.e., it should strictly	Eelco Dolstra	2	-0/+4
	evaluate its arguments.
2006-08-24	* New primop __toXML (or builtins.toXML) to convert an expression to	Eelco Dolstra	2	-0/+2
	an XML representation stored in a string. This should be useful to pass structured information to builders.
2006-08-23	* New primop: abort "error message".	Eelco Dolstra	1	-0/+1

2006-08-23	* A new primop `builtins', which returns an attribute set containing	Eelco Dolstra	2	-0/+13
	all the primops. This allows Nix expressions to test for new primops and take appropriate action if they're not available. For instance, rather than calling a primop `foo' directly, they could say `if builtins ? foo then builtins.foo ... else ...'.
2006-08-22	* Urgh (see NIX-56).	Eelco Dolstra	1	-1/+0

2006-08-17	* Test for `nix-instantiate --eval-only --xml'.	Eelco Dolstra	3	-0/+56

2006-08-16	* Meh.	Eelco Dolstra	1	-2/+2

2006-08-16	* A test for NIX-53.	Eelco Dolstra	2	-0/+18

2006-07-24	* New language feature: domain checks, which check whether a function	Eelco Dolstra	1	-0/+7
	argument has a valid value, i.e., is in a certain domain. E.g., { foo : [true false] , bar : ["a" "b" "c"] }: ... This previously could be done using assertions, but domain checks will allow the buildfarm to automatically extract the configuration space from functions.
2006-07-24	* Tests for domain checks.	Eelco Dolstra	3	-0/+15

2006-07-24	* Refactoring to support domain checks.	Eelco Dolstra	3	-3/+3

2006-07-10	* This expression has an undefined variable which isn't detected, so	Eelco Dolstra	1	-0/+11
	evaluation fails: error: impossible: undefined variable `gcc'
2006-05-08	* Allow function argument default values to refer to other arguments	Eelco Dolstra	2	-0/+2
	of the function. Implements NIX-45.
2006-05-02	* More tests.	Eelco Dolstra	3	-1/+9

2006-05-02	* Tests for NIX-45.	Eelco Dolstra	3	-0/+21

2006-05-01	* String interpolation. Expressions like	Eelco Dolstra	2	-2/+10
	"--with-freetype2-library=" + freetype + "/lib" can now be written as "--with-freetype2-library=${freetype}/lib" An arbitrary expression can be enclosed within ${...}, not just identifiers. * Escaping in string literals: \n, \r, \t interpreted as in C, any other character following \ is interpreted as-is. * Newlines are now allowed in string literals.
2006-05-01	* Allow string concatenations involving derivations, e.g.,	Eelco Dolstra	2	-2/+2
	configureFlags = "--with-freetype2-library=" + freetype + "/lib";
2006-03-01	* More test coverage.	Eelco Dolstra	7	-0/+15

2005-11-17	* "Fix" the test, since we cannot feasibly support the intended semantics.	Eelco Dolstra	1	-1/+1

2005-11-04	* Scoping bug in `with'.	Eelco Dolstra	2	-0/+14

2005-07-25	* Added a list concatenation operator:	Eelco Dolstra	2	-0/+2
	[1 2 3] ++ [4 5 6] => [1 2 3 4 5 6]
2005-05-18	* Added a primop `removeAttrs' to remove attributes from a set, e.g.,	Eelco Dolstra	3	-0/+11
	`removeAttrs attrs ["x", "y"]' returns the set `attrs' with the attributes named `x' and `y' removed. It is not an error for the named attributes to be missing from the input set.
2005-03-10	* Check for duplicate attributes and formal parameters in Nix	Eelco Dolstra	5	-0/+31
	expressions.
2004-10-27	* Use `atdiff' instead of `cmp' for checking test output.	Eelco Dolstra	2	-3/+3
	* Don't use local file names in tests since they will produce different parse trees depending on the current directory.
2004-10-27	* Bug fix in parsing of /* ... */ comments; due to longest match	Eelco Dolstra	2	-0/+12
	regexp there could be only one such comment per file.
