2007-01-15 * Handle multiple indirect symlinks when loading a Nix expression.Eelco Dolstra1-3/+6
2007-01-15 * builtins.filterSource: pass the type of the file ("regular",Eelco Dolstra1-1/+18
"directory", "symlink") as the second argument to the filter predicate.
2007-01-14 * Option --argstr for passing string arguments easily. (NIX-75)Eelco Dolstra3-2/+51
2007-01-13 * Canonicalise ASTs in `nix-instantiate --eval': remove positionEelco Dolstra2-0/+44
info, sort attribute sets.
2007-01-13 * Memoize strict evaluation.Eelco Dolstra2-13/+29
2007-01-13 * printTermAsXML: treat derivations specially; emit an elementEelco Dolstra1-11/+55
<derivation outPath=... drvPath=...> attrs </derivation>. Only emit the attributes of any specific derivation only. This prevents exponententially large XML output due to the absense of sharing.
2007-01-13 * Make printing an expression as XML interruptible.Eelco Dolstra2-0/+7
2007-01-13 * Cleanup.Eelco Dolstra5-15/+15
2006-12-13 * Remove debug message.Eelco Dolstra1-1/+0
2006-12-12 * New primop builtins.filterSource, which can be used to filter filesEelco Dolstra1-0/+38
from a source directory. All files for which a predicate function returns true are copied to the store. Typical example is to leave out the .svn directory: stdenv.mkDerivation { ... src = builtins.filterSource (path: baseNameOf (toString path) != ".svn") ./source-dir; # as opposed to # src = ./source-dir; } This is important because the .svn directory influences the hash in a rather unpredictable and variable way.
2006-12-12 * New built-in function `builtins.attrNames' that returns theEelco Dolstra1-0/+21
names of the attributes in an attribute set.
2006-12-02 * Remove SwitchToOriginalUser, we're not going to need it anymore.Eelco Dolstra1-2/+0
2006-12-01 * Replace read-only calls to addTextToStore.Eelco Dolstra1-1/+3
2006-12-01 * Merge addToStore and addToStoreFixed.Eelco Dolstra1-1/+4
* addToStore now adds unconditionally, it doesn't use readOnlyMode. Read-only operation is up to the caller (who can call computeStorePathForPath).
2006-11-30 * Put building in the store API.Eelco Dolstra1-2/+1
2006-11-30 * Refactoring. There is now an abstract interface class StoreAPIEelco Dolstra2-5/+5
containing functions that operate on the Nix store. One implementation is LocalStore, which operates on the Nix store directly. The next step, to enable secure multi-user Nix, is to create a different implementation RemoteStore that talks to a privileged daemon process that uses LocalStore to perform the actual operations.
2006-11-03 * Fix importing of derivation outputs.Eelco Dolstra1-2/+9
2006-10-23 * Some better error messages.Eelco Dolstra2-5/+12
2006-10-19 * Better message.Eelco Dolstra1-1/+1
2006-10-19 * toFile: maintain the references.Eelco Dolstra1-10/+4
2006-10-17 * Backwards compatibility hack for user environments made by Nix <= 0.10.Eelco Dolstra1-0/+7
2006-10-17 * Backwards compatibility with old user environment manifests.Eelco Dolstra1-1/+2
2006-10-17 * Print out the offending path.Eelco Dolstra1-2/+3
2006-10-17 * An awful backwards compatibility hack.Eelco Dolstra1-0/+24
2006-10-17 * baseNameOf: paths don't have to be absolute.Eelco Dolstra1-1/+1
2006-10-17 * toPath: should be the identity on paths.Eelco Dolstra1-3/+1
2006-10-17 * dirOf: return a path if the argument is a path.Eelco Dolstra1-2/+6
2006-10-17 * toString: don't copy paths. So toString can be used to passEelco Dolstra1-3/+4
non-store paths to a builder.
2006-10-17 * Do the path check on the normal form.Eelco Dolstra1-2/+5
2006-10-16 * Big cleanup of the semantics of paths, strings, contexts, stringEelco Dolstra11-370/+303
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'.)
2006-10-11 * Removed URIs from the evaluator (NIX-66). They are now just anotherEelco Dolstra6-13/+4
kind of notation for strings.
2006-10-10 * Quick hack to fix NIX-67: evaluation result differing if the NixEelco Dolstra2-13/+16
expression resides in the store.
2006-10-10 * `import': unwrap the context. Necessary to make `import (x + y)'Eelco Dolstra1-13/+14
work, where x is a store path.
2006-10-03 * toXML: propagate the context to allow derivations to be used in theEelco Dolstra3-9/+18
argument.
2006-10-03 * toFile: added an additional argument to specify the store pathEelco Dolstra3-4/+40
suffix, e.g., `builtins.toFile "builder.sh" "..."'. * toFile: handle references to other files correctly.
2006-10-02 * Finally, a real "let" syntax: `let x = ...; ... z = ...; in ...'.Eelco Dolstra2-1/+4
2006-10-02 * Hack for Bison 2.3 compatability.Eelco Dolstra2-2/+14
2006-09-24 * The result of a concatenation with a derivation on the left-handEelco Dolstra2-4/+13
side should be a path, I guess. * Handle paths that are in the store but not direct children of the store directory. * Ugh, hack to prevent double context wrapping.
2006-09-24 * Primop `toPath' to convert a string to a path.Eelco Dolstra1-7/+26
* Primop `pathExists' to check for path existence.
2006-09-24 * Builtin function `getEnv' for getting environment variables.Eelco Dolstra1-6/+18
2006-09-24 * lessThan primitive for integer comparison.Eelco Dolstra1-0/+9
2006-09-22 * Builtin function `add' to add integers.Eelco Dolstra3-0/+20
* 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 Dolstra1-0/+9
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 ofEelco Dolstra1-0/+25
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 forEelco Dolstra1-0/+16
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)
2006-09-21 * Fix comment.Eelco Dolstra1-3/+1
2006-09-20 * Shut up a warning.Eelco Dolstra1-0/+1
2006-09-20 * Print a better error message for wrong hashes (NIX-49).Eelco Dolstra1-3/+6
2006-09-11 * Support `++'.Eelco Dolstra1-6/+14
* More follow restrictions on layout.
2006-09-05 * Sone missing #includes.Eelco Dolstra1-0/+1
