2024-03-25Overhaul completions, redo #6693 (#8131)John Ericson
As I complained in https://github.com/NixOS/nix/pull/6784#issuecomment-1421777030 (a comment on the wrong PR, sorry again!), #6693 introduced a second completions mechanism to fix a bug. Having two completion mechanisms isn't so nice. As @thufschmitt also pointed out, it was a bummer to go from `FlakeRef` to `std::string` when collecting flake refs. Now it is `FlakeRefs` again. The underlying issue that sought to work around was that completion of arguments not at the end can still benefit from the information from latter arguments. To fix this better, we rip out that change and simply defer all completion processing until after all the (regular, already-complete) arguments have been passed. In addition, I noticed the original completion logic used some global variables. I do not like global variables, because even if they save lines of code, they also obfuscate the architecture of the code. I got rid of them moved them to a new `RootArgs` class, which now has `parseCmdline` instead of `Args`. The idea is that we have many argument parsers from subcommands and what-not, but only one root args that owns the other per actual parsing invocation. The state that was global is now part of the root args instead. This did, admittedly, add a bunch of new code. And I do feel bad about that. So I went and added a lot of API docs to try to at least make the current state of things clear to the next person. -- This is needed for RFC 134 (tracking issue #7868). It was very hard to modularize `Installable` parsing when there were two completion arguments. I wouldn't go as far as to say it is *easy* now, but at least it is less hard (and the completions test finally passed).

2023-04-07Finish converting existing comments for internal API docs (#8146)John Ericson
* Finish converting existing comments for internal API docs 99% of this was just reformatting existing comments. Only two exceptions: - Expanded upon `BuildResult::status` compat note - Split up file-level `symbol-table.hh` doc comments to get per-definition docs Also fixed a few whitespace goofs, turning leading tabs to spaces and removing trailing spaces. Picking up from #8133 * Fix two things from comments * Use triple-backtick not indent for `dumpPath` * Convert GNU-style `\`..'` quotes to markdown style in API docs This will render correctly.

2023-01-10Make clear that `StorePathWithOutputs` is a deprecated typeJohn Ericson
- Add a comment - Put `OutputsSpec` in a different header (First part of #6815) - Make a few stray uses of it in new code use `DerivedPath` instead.

2021-12-06RunPager: restore stdout upon pager exitAlexander Bantyev
Before this change, stdout was closed after the pager exits. This is fine for non-interactive commands where we want to exit right after the pager exits anyways, but for interactive things (e.g. nix repl) this breaks the output after we quit the pager. Keep the initial stdout fd as part of RunPager, and restore it in RunPager::~RunPager using dup2.

2021-04-05Rename BuildableJohn Ericson
2021-04-05Use `BuildableReq` for `buildPaths` and `ensurePath`John Ericson
This avoids an ambiguity where the `StorePathWithOutputs { drvPath, {} }` could mean "build `brvPath`" or "substitute `drvPath`" depending on context. It also brings the internals closer in line to the new CLI, by generalizing the `Buildable` type is used there and makes that distinction already. In doing so, relegate `StorePathWithOutputs` to being a type just for backwards compatibility (CLI and RPC).

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).

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.)

2012-11-20nix-store -r: Add ‘--ignore-unknown’ flagEelco Dolstra
This flag causes paths that do not have a known substitute to be quietly ignored. This is mostly useful for Charon, allowing it to speed up deployment by letting a machine use substitutes for all substitutable paths, instead of uploading them. The latter is frequently faster, e.g. if the target machine has a fast Internet connection while the source machine is on a slow ADSL line.

I.e. do what git does. I'm too lazy to keep the builtin help text up to date :-) Also add ‘--help’ to various commands that lacked it (e.g. nix-collect-garbage).
2012-08-24Include the output name in the GC root linkEelco Dolstra
Output names are now appended to resulting GC symlinks, e.g. by nix-build. For backwards compatibility, if the output is named "out", nothing is appended. E.g. doing "nix-build -A foo" on a derivation that produces outputs "out", "bin" and "dev" will produce symlinks "./result", "./result-bin" and "./result-dev", respectively.
