2015-02-19	Allow the leading component of a path to be a ~	Shea Levy	1	-0/+2

2014-08-20	Use proper quotes everywhere	Eelco Dolstra	1	-1/+1

2014-01-14	Allow "bare" dynamic attrs	Shea Levy	1	-0/+2
	Now, in addition to a."${b}".c, you can write a.${b}.c (applicable wherever dynamic attributes are valid). Signed-off-by: Shea Levy <shea@shealevy.com>
2013-09-02	Fix whitespace	Eelco Dolstra	1	-5/+5

2013-08-19	Store Nix integers as longs	Eelco Dolstra	1	-2/+4
	So on 64-bit systems, integers are now 64-bit. Fixes #158.
2013-08-02	Add comparison operators ‘<’, ‘<=’, ‘>’ and ‘>=’	Eelco Dolstra	1	-0/+2

2013-03-14	Fix building against Bison 2.6	Eelco Dolstra	1	-1/+0

2012-09-27	Allow dashes in identifiers	Eelco Dolstra	1	-1/+1
	In Nixpkgs, the attribute in all-packages.nix corresponding to a package is usually equal to the package name. However, this doesn't work if the package contains a dash, which is fairly common. The convention is to replace the dash with an underscore (e.g. "dbus-lib" becomes "dbus_glib"), but that's annoying. So now dashes are valid in variable / attribute names, allowing you to write: dbus-glib = callPackage ../development/libraries/dbus-glib { }; and buildInputs = [ dbus-glib ]; Since we don't have a negation or subtraction operation in Nix, this is unambiguous.
2011-08-06	* Add a Nix expression search path feature. Paths between angle	Eelco Dolstra	1	-0/+2
	brackets, e.g. import <nixpkgs/pkgs/lib> are resolved by looking them up relative to the elements listed in the search path. This allows us to get rid of hacks like import "${builtins.getEnv "NIXPKGS_ALL"}/pkgs/lib" The search path can be specified through the ‘-I’ command-line flag and through the colon-separated ‘NIX_PATH’ environment variable, e.g., $ nix-build -I /etc/nixos ... If a file is not found in the search path, an error message is lazily thrown.
2011-07-13	* Allow a default value in attribute selection by writing	Eelco Dolstra	1	-0/+1
	x.y.z or default (as originally proposed in https://mail.cs.uu.nl/pipermail/nix-dev/2009-September/002989.html). For instance, an expression like stdenv.lib.attrByPath ["features" "ckSched"] false args can now be written as args.features.ckSched or false
2010-10-23	* Optimise string constants by putting them in the symbol table.	Eelco Dolstra	1	-4/+4

2010-05-06	* Store attribute positions in the AST and report duplicate attribute	Eelco Dolstra	1	-5/+8
	errors with position info. * For all positions, use the position of the first character of the first token, rather than the last character of the first token plus one.
2010-04-21	* Fix the interpretation of ''\<character> in indented strings.	Eelco Dolstra	1	-1/+1

2010-04-12	* Indented strings.	Eelco Dolstra	1	-9/+10

2010-04-12	* More missing constructs.	Eelco Dolstra	1	-3/+1

2010-04-12	* Don't use ATerms for the abstract syntax trees anymore. Not	Eelco Dolstra	1	-12/+12
	finished yet.
2010-04-12	* Don't use ATerms to represent integers in the lexer.	Eelco Dolstra	1	-1/+1

2008-08-14	* Added an experimental feature suggested by Andres: ellipses ("...")	Eelco Dolstra	1	-0/+1
	in attribute set pattern matches. This allows defining a function that takes at least the listed attributes, while ignoring additional attributes. For instance, {stdenv, fetchurl, fuse, ...}: stdenv.mkDerivation { ... }; defines a function that requires an attribute set that contains the specified attributes but ignores others. The main advantage is that we can then write in all-packages.nix aefs = import ../bla/aefs pkgs; instead of aefs = import ../bla/aefs { inherit stdenv fetchurl fuse; }; This saves a lot of typing (not to mention not having to update all-packages.nix with purely mechanical changes). It saves as much typing as the "args: with args;" style, but has the advantage that the function arguments are properly declared (not implicit in what the body of the "with" uses).
2008-02-05	* Fix the parsing of	Eelco Dolstra	1	-1/+5
	'' '${foo}' '' where the antiquote should work as expected, instead of giving the string "'${foo}'".
2007-12-06	* Syntax to escape '', ${.	Eelco Dolstra	1	-0/+12

2007-11-30	* Added a new kind of multi-line string literal delimited by two	Eelco Dolstra	1	-0/+15
	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.
2006-10-16	* Big cleanup of the semantics of paths, strings, contexts, string	Eelco Dolstra	1	-1/+1
	concatenation and string coercion. This was a big mess (see e.g. NIX-67). Contexts are now folded into strings, so that they don't cause evaluation errors when they're not expected. The semantics of paths has been clarified (see nixexpr-ast.def). toString() and coerceToString() have been merged. Semantic change: paths are now copied to the store when they're in a concatenation (and in most other situations - that's the formalisation of the meaning of a path). So "foo " + ./bla evaluates to "foo /nix/store/hash...-bla", not "foo /path/to/current-dir/bla". This prevents accidental impurities, and is more consistent with the treatment of derivation outputs, e.g., `"foo " + bla' where `bla' is a derivation. (Here `bla' would be replaced by the output path of `bla'.)
2006-10-02	* Finally, a real "let" syntax: `let x = ...; ... z = ...; in ...'.	Eelco Dolstra	1	-0/+1

2006-10-02	* Hack for Bison 2.3 compatability.	Eelco Dolstra	1	-0/+1

2006-09-04	* Compile the lexer as C++ code. Remove all the redundant C/C++	Eelco Dolstra	1	-6/+38
	marshalling code.
2006-09-04	* Use a proper namespace.	Eelco Dolstra	1	-2/+6
	* Optimise header file usage a bit. * Compile the parser as C++.
2006-09-01	* Allow "$" in strings as long as they are not followed by "{". (Too	Eelco Dolstra	1	-1/+5
	bad flex doesn't have lexical restrictions, the current solution isn't quite right...)
2006-08-16	* Handle carriage returns. Fixes NIX-53.	Eelco Dolstra	1	-2/+6

2006-05-01	* Disallow unescaped $ in string literals.	Eelco Dolstra	1	-4/+1

2006-05-01	* String interpolation. Expressions like	Eelco Dolstra	1	-9/+32
	"--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.
2005-07-25	* Added a list concatenation operator:	Eelco Dolstra	1	-0/+1
	[1 2 3] ++ [4 5 6] => [1 2 3 4 5 6]
2004-10-27	* Bug fix in parsing of /* ... */ comments; due to longest match	Eelco Dolstra	1	-1/+1
	regexp there could be only one such comment per file.
2004-10-25	* New language feature: with expressions.	Eelco Dolstra	1	-0/+1
	The expression `with E1; E2' evaluates to E2 with all bindings in the attribute set E1 substituted. E.g., with {x = 123;}; x evaluates to 123. That is, the attribute set E1 is in scope in E2. This is particularly useful when importing files containing lots definitions. E.g., instead of let { inherit (import ./foo.nix) a b c d e f; body = ... a ... f ...; } we can now say with import ./foo.nix; ... a ... f ... I.e., we don't have to say what variables should be brought into scope.
2004-03-28	* Added plain lambdas, e.g., `let { id = x: x; const = x: y: x; }'.	Eelco Dolstra	1	-1/+1
	`bla:' is now no longer parsed as a URL. * Re-enabled support for the `args' attribute in derivations to specify command line arguments to the builder, e.g., ... builder = /usr/bin/python; args = ["-c" ./builder.py]; ...
2004-02-04	* An attribute set update operator (//). E.g.,	Eelco Dolstra	1	-0/+1
	{x=1; y=2; z=3;} // {y=4;} => {x=1; y=4; z=3;}
2004-02-02	* Added syntactic sugar to the construction of attribute sets to	Eelco Dolstra	1	-0/+1
	`inherit' variables from the surrounding lexical scope. E.g., {stdenv, libfoo}: derivation { builder = ./bla; inherit stdenv libfoo; xyzzy = 1; } is equivalent to {stdenv, libfoo}: derivation { builder = ./bla; stdenv = stdenv; libfoo = libfoo; xyzzy = 1; } Note that for mutually recursive attribute set definitions (`rec {...}'), this also works, that is, `rec {inherit x;}' is equivalent to `let {fresh = x; body = rec {x = fresh;};}', not `rec {x = x}'.
2004-01-30	* Parser numbers again.	Eelco Dolstra	1	-1/+4
	* Include missing files in distributions.
2004-01-30	* Replaced the SDF parser by a substantially faster Bison/Flex	Eelco Dolstra	1	-0/+78
	parser (roughly 80x faster). The absolutely latest version of Bison (1.875c) is required for reentrant GLR support, as well as a recent version of Flex (say, 2.5.31). Note that most Unix distributions ship with the prehistoric Flex 2.5.4, which doesn't support reentrancy.
