2020-05-04Flag: Use designated initializersEelco Dolstra
2020-03-30Backport 'nix dev-shell' from the flakes branchEelco Dolstra
This also adds a '--profile' option to 'nix build' (replacing 'nix-env --set').
2019-12-10Make the Store API more type-safeEelco Dolstra
Most functions now take a StorePath argument rather than a Path (which is just an alias for std::string). The StorePath constructor ensures that the path is syntactically correct (i.e. it looks like <store-dir>/<base32-hash>-<name>). Similarly, functions like buildPaths() now take a StorePathWithOutputs, rather than abusing Path by adding a '!<outputs>' suffix. Note that the StorePath type is implemented in Rust. This involves some hackery to allow Rust values to be used directly in C++, via a helper type whose destructor calls the Rust type's drop() function. The main issue is the dynamic nature of C++ move semantics: after we have moved a Rust value, we should not call the drop function on the original value. So when we move a value, we set the original value to bitwise zero, and the destructor only calls drop() if the value is not bitwise zero. This should be sufficient for most types. Also lots of minor cleanups to the C++ API to make it more modern (e.g. using std::optional and std::string_view in some places).
2019-12-05Make subcommand construction in MultiCommand lazyEelco Dolstra
(cherry picked from commit a0de58f471c9087d8e6cc60a6078f9940a125b15)

(cherry picked from commit f70434b1fbbdb0e188718f0c55a8156a7aa08744)
2019-12-05MultiCommand: Simplify constructionEelco Dolstra
(cherry picked from commit 15a16e5c05d547ec07170df2392263e5e891447b)
2019-11-22getEnv(): Return std::optionalEelco Dolstra
This allows distinguishing between an empty value and no value.
2019-11-08Move editorFor srom libutil to nixEelco Dolstra
libutil should not depend on libexpr.
2019-10-21Allow content-addressable paths to have referencesEelco Dolstra
This adds a command 'nix make-content-addressable' that rewrites the specified store paths into content-addressable paths. The advantage of such paths is that 1) they can be imported without signatures; 2) they can enable deduplication in cases where derivation changes do not cause output changes (apart from store path hashes). For example, $ nix make-content-addressable -r nixpkgs.cowsay rewrote '/nix/store/g1g31ah55xdia1jdqabv1imf6mcw0nb1-glibc-2.25-49' to '/nix/store/48jfj7bg78a8n4f2nhg269rgw1936vj4-glibc-2.25-49' ... rewrote '/nix/store/qbi6rzpk0bxjw8lw6azn2mc7ynnn455q-cowsay-3.03+dfsg1-16' to '/nix/store/iq6g2x4q62xp7y7493bibx0qn5w7xz67-cowsay-3.03+dfsg1-16' We can then copy the resulting closure to another store without signatures: $ nix copy --trusted-public-keys '' ---to ~/my-nix /nix/store/iq6g2x4q62xp7y7493bibx0qn5w7xz67-cowsay-3.03+dfsg1-16 In order to support self-references in content-addressable paths, these paths are hashed "modulo" self-references, meaning that self-references are zeroed out during hashing. Somewhat annoyingly, this means that the NAR hash stored in the Nix database is no longer necessarily equal to the output of "nix hash-path"; for content-addressable paths, you need to pass the --modulo flag: $ nix path-info --json /nix/store/iq6g2x4q62xp7y7493bibx0qn5w7xz67-cowsay-3.03+dfsg1-16 | jq -r .[].narHash sha256:0ri611gdilz2c9rsibqhsipbfs9vwcqvs811a52i2bnkhv7w9mgw $ nix hash-path --type sha256 --base32 /nix/store/iq6g2x4q62xp7y7493bibx0qn5w7xz67-cowsay-3.03+dfsg1-16 1ggznh07khq0hz6id09pqws3a8q9pn03ya3c03nwck1kwq8rclzs $ nix hash-path --type sha256 --base32 /nix/store/iq6g2x4q62xp7y7493bibx0qn5w7xz67-cowsay-3.03+dfsg1-16 --modulo iq6g2x4q62xp7y7493bibx0qn5w7xz67 0ri611gdilz2c9rsibqhsipbfs9vwcqvs811a52i2bnkhv7w9mgw
2018-03-29Remove reference to non-existent manpagesEelco Dolstra
2017-10-24nix: Respect -I, --arg, --argstrEelco Dolstra
Also, random cleanup to argument handling.
2017-10-23Turn $NIX_REMOTE into a configuration optionEelco Dolstra
2017-09-27nix copy: make recursive by defaultEelco Dolstra
2017-09-10nix build: Only download the requested derivation outputsEelco Dolstra
Also some refactoring.
2017-09-08nix copy: Don't open the --from store twiceEelco Dolstra
2017-08-29Hide commands that don't have a descriptionEelco Dolstra
These are assumed to be internal.

2017-07-14StorePathsCommand: Don't build installablesEelco Dolstra
On second though this was annoying. E.g. "nix log nixpkgs.hello" would build/download Hello first, even though the log can be fetched directly from the binary cache. May need to revisit this.
2017-07-14nix: Show help when no arguments are givenEelco Dolstra
Fixes #1464.
2017-05-04nix dump-path: AddEelco Dolstra
This is primarily useful for extracting NARs from other stores (like binary caches), which "nix-store --dump" cannot do.
2017-04-25StorePathCommands: Build installablesEelco Dolstra
So for instance "nix copy --to ... nixpkgs.hello" will build nixpkgs.hello first. It's debatable whether this is a good idea. It seems desirable for commands like "nix copy" but maybe not for commands like "nix path-info".
2017-04-25Make StorePathsCommand a subclass of InstallablesCommandEelco Dolstra
This allows commands like 'nix path-info', 'nix copy', 'nix verify' etc. to work on arbitrary installables. E.g. to copy geeqie to a binary cache: $ nix copy -r --to file:///tmp/binary-cache nixpkgs.geeqie Or to get the closure size of thunderbird: $ nix path-info -S nixpkgs.thunderbird
2017-04-25Restructure installables handling in the "nix" commandEelco Dolstra
2017-03-16nix copy: Make -r option use the "from" storeEelco Dolstra
Previously, we tried to compute the closure in the local store, which obviously doesn't work.
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...
2016-11-25Get rid of unicode quotes (#1140)Guillaume Maudoux
2016-11-10Store::computeFSClosure(): Support a set of pathsEelco Dolstra
This way, callers can exploits the parallelism of computeFSClosure() when they have multiple paths that they need the (combined) closure of.
2016-09-02Merge openStore and openStoreAt with default argumentsShea Levy
2016-06-01Make the store directory a member variable of StoreEelco Dolstra
2016-05-04Add a Store::addToStore() variant that accepts a NAREelco Dolstra
As a side effect, this ensures that signatures are propagated when copying paths between stores. Also refactored import/export to make use of this.
2016-04-21nix --help: Show usage examplesEelco Dolstra
2016-04-15Unify "nix verify-paths" and "nix verify-store"Eelco Dolstra
"verify-store" is now simply an "--all" flag to "nix verify". This flag can be used for any other store path command as well (e.g. "nix path-info", "nix copy-sigs", ...).
2016-03-29Add "nix verify-paths" commandEelco Dolstra
Unlike "nix-store --verify-path", this command verifies signatures in addition to store path contents, is multi-threaded (especially useful when verifying binary caches), and has a progress indicator. Example use: $ nix verify-paths --store https://cache.nixos.org -r $(type -p thunderbird) ... [17/132 checked] checking ‘/nix/store/rawakphadqrqxr6zri2rmnxh03gqkrl3-autogen-5.18.6’
2016-03-21nix: Add --store flagEelco Dolstra
This is a bit user-friendlier than using $NIX_REMOTE.
