The parser allowed senseless `a > b > c` but disallowed `a -> b -> c` which seems valid It might be a typo
2018-05-11Revert "Throw a specific error for incomplete parse errors."Eelco Dolstra
This reverts commit 6498adb002bcf7e715afe46c23b8635d4592c156. We don't actually use IncompleteParseError in 'nix repl'.

Fixes #2077.
2017-11-03Remove git:// support in NIX_PATHEelco Dolstra
This didn't support specifying a revision/branch, and was restricted to git:// URIs (since https:// or ssh:// would be ambiguous).
2017-10-30builtins.fetchgit: Support importing a working treeEelco Dolstra
For example, you can write src = fetchgit ./.; and if ./. refers to an unclean working tree, that tree will be copied to the Nix store. This removes the need for "cleanSource".
2017-10-30builtins.fetchGit: Return an attrset with revision infoEelco Dolstra
This adds rev, shortRev and revCount attributes, equal to what Hydra provides. E.g. $ nix eval '(fetchGit https://github.com/NixOS/patchelf.git)' { outPath = "/nix/store/ghigrkw02l440g8vfxa9wj4c3zpfmw99-source"; rev = "29c085fd9d3fc972f75b3961905d6b4ecce7eb2b"; revCount = 303; shortRev = "29c085f"; }

2017-07-26nix-build/nix-shell: Eliminate call to nix-instantiate / nix-storeEelco Dolstra
Note that this removes the need for a derivation symlink, so the --drv-path and --add-drv-link flags now do nothing.

2016-11-26Revert "Get rid of unicode quotes (#1140)"Eelco Dolstra
This reverts commit f78126bfd6b6c8477fcdbc09b2f98772dbe9a1e7. There really is no need for such a massive change...

2016-09-14Enable HTTP/2 supportEelco Dolstra
The binary cache store can now use HTTP/2 to do lookups. This is much more efficient than HTTP/1.1 due to multiplexing: we can issue many requests in parallel over a single TCP connection. Thus it's no longer necessary to use a bunch of concurrent TCP connections (25 by default). For example, downloading 802 .narinfo files from https://cache.nixos.org/, using a single TCP connection, takes 11.8s with HTTP/1.1, but only 0.61s with HTTP/2. This did require a fairly substantial rewrite of the Downloader class to use the curl multi interface, because otherwise curl wouldn't be able to do multiplexing for us. As a bonus, we get connection reuse even with HTTP/1.1. All downloads are now handled by a single worker thread. Clients call Downloader::enqueueDownload() to tell the worker thread to start the download, getting a std::future to the result.
2016-04-29Support Git repos in the Nix pathEelco Dolstra
E.g. $ nix-build -I nixpkgs=git://github.com/NixOS/nixpkgs '<nixpkgs>' -A hello This is not extremely useful yet because you can't specify a branch/revision.
2016-04-14Make the search path lazier with non-fatal errorsEelco Dolstra
Thus, -I / $NIX_PATH entries are now downloaded only when they are needed for evaluation. An error to download an entry is a non-fatal warning (just like non-existant paths). This does change the semantics of builtins.nixPath, which now returns the original, rather than resulting path. E.g., before we had [ { path = "/nix/store/hgm3yxf1lrrwa3z14zpqaj5p9vs0qklk-nixexprs.tar.xz"; prefix = "nixpkgs"; } ... ] but now [ { path = "https://nixos.org/channels/nixos-16.03/nixexprs.tar.xz"; prefix = "nixpkgs"; } ... ] Fixes #792.
2016-02-29Add an HTTP binary cache storeEelco Dolstra
Allowing stuff like NIX_REMOTE=https://cache.nixos.org nix-store -qR /nix/store/x1p1gl3a4kkz5ci0nfbayjqlqmczp1kq-geeqie-1.1 or NIX_REMOTE=https://cache.nixos.org nix-store --export /nix/store/x1p1gl3a4kkz5ci0nfbayjqlqmczp1kq-geeqie-1.1 | nix-store --import
2016-02-24Throw a specific error for incomplete parse errors.Scott Olson
`nix-repl` will use this for deciding whether to keep waiting for input or error out right away.
2016-02-12Merge pull request #762 from ctheune/ctheune-floatsEelco Dolstra
Implement floats
2016-02-04Eliminate the "store" global variableEelco Dolstra
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.)

2015-05-06nix-env/nix-instantiate/nix-build: Support URIsEelco Dolstra
For instance, you can install Firefox from a specific Nixpkgs revision like this: $ nix-env -f https://github.com/NixOS/nixpkgs/archive/63def04891a0abc328b1b0b3a78ec02c58f48583.tar.gz -iA firefox Or build a package from the latest nixpkgs-unstable channel: $ nix-build https://nixos.org/channels/nixpkgs-unstable/nixexprs.tar.xz -A hello
2015-05-05Allow URLs in the Nix search pathEelco Dolstra
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
2015-02-23Add restricted evaluation modeEelco Dolstra
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.

2014-10-05Get rid of some unnecessary ExprConcatStrings nodes in dynamic attrsEelco Dolstra
This gives a ~18% speedup in NixOS evaluation (after converting most calls to hasAttr/getAttr to dynamic attrs).

2014-07-30Rename nixPath to __nixPathEelco Dolstra
The name ‘nixPath’ breaks existing code.
2014-05-26Remove ExprBuiltinEelco Dolstra
It's slower than ExprVar since it doesn't compute a static displacement. Since we're not using the throw primop in the implementation of <...> anymore, it's also not really needed.
2014-05-26Make the Nix search path declarativeEelco Dolstra
Nix search path lookups like <nixpkgs> are now desugared to ‘findFile nixPath <nixpkgs>’, where ‘findFile’ is a new primop. Thus you can override the search path simply by saying let nixPath = [ { prefix = "nixpkgs"; path = "/my-nixpkgs"; } ]; in ... <nixpkgs> ... In conjunction with ‘scopedImport’ (commit c273c15cb13bb86420dda1e5341a4e19517532b5), the Nix search path can be propagated across imports, e.g. let overrides = { nixPath = [ ... ] ++ builtins.nixPath; import = fn: scopedImport overrides fn; scopedImport = attrs: fn: scopedImport (overrides // attrs) fn; builtins = builtins // overrides; }; in scopedImport overrides ./nixos
2014-05-26Ensure that -I flags get included in nixPathEelco Dolstra
Also fixes #261.
2014-05-26Add primop ‘scopedImport’Eelco Dolstra
‘scopedImport’ works like ‘import’, except that it takes a set of attributes to be added to the lexical scope of the expression, essentially extending or overriding the builtin variables. For instance, the expression scopedImport { x = 1; } ./foo.nix where foo.nix contains ‘x’, will evaluate to 1. This has a few applications: * It allows getting rid of function argument specifications in package expressions. For instance, a package expression like: { stdenv, fetchurl, libfoo }: stdenv.mkDerivation { ... buildInputs = [ libfoo ]; } can now we written as just stdenv.mkDerivation { ... buildInputs = [ libfoo ]; } and imported in all-packages.nix as: bar = scopedImport pkgs ./bar.nix; So whereas we once had dependencies listed in three places (buildInputs, the function, and the call site), they now only need to appear in one place. * It allows overriding builtin functions. For instance, to trace all calls to ‘map’: let overrides = { map = f: xs: builtins.trace "map called!" (map f xs); # Ensure that our override gets propagated by calls to # import/scopedImport. import = fn: scopedImport overrides fn; scopedImport = attrs: fn: scopedImport (overrides // attrs) fn; # Also update ‘builtins’. builtins = builtins // overrides; }; in scopedImport overrides ./bla.nix * Similarly, it allows extending the set of builtin functions. For instance, during Nixpkgs/NixOS evaluation, the Nixpkgs library functions could be added to the default scope. There is a downside: calls to scopedImport are not memoized, unlike import. So importing a file multiple times leads to multiple parsings / evaluations. It would be possible to construct the AST only once, but that would require careful handling of variables/environments.
