This is used in in the manual generation for option identifiers that can
be linked. This, unike what the example describes, doesn't preserve
quotes which is needed for these identifiers to be valid.
This reverts commit 124cccbe3b.
124cccbe3b
broke the build of NixOS manual.
It does not make sense to be as strict as with attributes since we
are not limited by the CLI's inability to handle numbers.
Placeholders should not be quoted either as they are not part of Nix
syntax but a meta-level construct.

Currently, not providing `name` to `cleanSourceWith` will use the name
of the imported directory. However, a common case is for this to be the
top level of some repository. In that case, the name will be the name of
the checkout on the current machine, which is not necessarily
reproducible across different settings, and can lead to e.g. cache
misses in CI.
This is documented in the comment on `cleanSourceWith`, but this does
not stop it being a subtle trap for users.
There are different tradeoffs in each case:
1. If `cleanSourceWith` defaults to `"source"`, then we may end up with a
user not knowing what directory a source store path corresponds to.
However, it being called "unnamed" may give them a clue that there is a
way for them to name it, and lead them to the definition of the
function, which has a clear `name` parameter.
2. If `cleanSoureWith` defaults to the directory name, then a user may face
occasional loss of caching, which is hard to notice, and hard to track
down. Tracking it down likely requires use of more advanced tools like
`nix-diff`, and reading the source of a lot of nix code.
I think the downside of the status quo is worse.
This is really another iteration of
https://github.com/NixOS/nix/issues/1305: that led to adding the `name`
argument in the first place, this just makes us use a better default
`name`.
The _module option is added as an internal option set, and it messes up
the results of module evaluations, requiring people to manually filter
_modules out.
If people depend on this, they can still use config._module from inside
the modules, exposing _module as an explicitly declared user option. Or
alternatively with the _module attribute now returned by evalModules.
newlib is the default for most tools when no kernel is provided. Other
exist, but this seems like a safe default.

This helps with troubleshooting exceptions in config values, which were hard
to track down for options with many definitions.
The trace will look like:
error: while evaluating the attribute 'config.foo' at undefined position:
[...]
while evaluating the option `foo':
[...]
while evaluating definitions from `/home/user/mymod.nix':
while evaluating 'dischargeProperties' at /home/user/nixpkgs/lib/modules.nix:464:25, called from /home/user/nixpkgs/lib/modules.nix:392:137:
while evaluating the attribute 'value' at /home/user/nixpkgs/lib/modules.nix:277:44:
Value error!
where the `/home/user/mymod.nix` module is
{ lib, ... }: {
options.foo = lib.mkOption {
type = lib.types.lines;
};
config.foo = builtins.throw "Value error!";
}
In 87a19e9048 I merged staging-next into master using the GitHub gui as intended.
In ac241fb7a5 I merged master into staging-next for the next staging cycle, however, I accidentally pushed it to master.
Thinking this may cause trouble, I reverted it in 0be87c7979. This was however wrong, as it "removed" master.
This reverts commit 0be87c7979.
I merged master into staging-next but accidentally pushed it to master.
This should get us back to 87a19e9048.
This reverts commit ac241fb7a5, reversing
changes made to 76a439239e.
Let’s call them by what they are, option names.
`generators.mkValueStringDefault` is a better value string renderer
than plain `toString`.
Also add docs to all options.
The semantic difference between `encode` and `to` is not apparent.
Users are likely to confuse both functions (which leads to unexpected
error messages about the wrong types). Like in `generators.nix`, all
functions should be prefixed by `to`.
Furthermore, converting to a string depends on the target context. In
this case, it’s a POSIX shell, so we should name it that (compare
`escapeShellArg` in `strings.nix`).
We can later add versions that escape for embedding in e.g. python
scripts or similar.
lib/cli is very similar to generators, so it should follow largely the
same interface. Similar to how generators isn’t exported, we should
also namespace cli by default (plus “cli” is only three characters to
type).
Before c9214c394b and
9d396d2e42 if .git is symlink the version
would gracefully default to no git revision. With those changes an
exception is thrown instead.
This introduces a new function `pathIsGitRepo` that checks if
`commitIdFromGitRepo` fails without error so we don't have to
reimplement this logic again and can fail gracefully.
Not all modules use name attribute as the name of the submodule, for example,
environment.etc uses target. We will need to maintain a list of exceptions.
lib.commitIdFromGitRepo now resolves the refs from the
parent repository in case the supplied path is a file
containing the path to said repository. this adds support
for git-worktree and things alike. see gitrepository-layout(5).
this also:
- adds a new boolean function lib.pathIsRegularFile to
check whether a path is a regular file
- patches lib.revisionWithDefault and
the revision and versionSuffix attributes in
config.system.nixos in order to support git-worktrees
The standard attrsOf is strict in its *values*, meaning it's impossible to
access only one attribute value without evaluating all others as well.
lazyAttrsOf is a version that doesn't have that problem, at the expense
of conditional definitions not properly working anymore.
Without this change, accessing `mergedValue` from `mergeDefinitions` in
case there are no definitions will throw an error like
error: evaluation aborted with the following error message: 'This case should never happen.'
This change makes it throw the appropriate error
error: The option `foo' is used but not defined.
This is fully backwards compatible.
Fix the broken test in https://github.com/NixOS/nixpkgs/pull/77416
Apparently hydra uses `nix-build lib/tests/release.nix` to run all
tests, where IFD isn't allowed. Fortunately we can get around this with
builtins.toFile, which doesn't require IFD, but still can test the
properties we want.
This fixes imports from the store not being possible, which was caused by
https://github.com/NixOS/nixpkgs/pull/76857
E.g. such a case:
imports = [ "${home-manager}/nixos" ];
With this change, disabledModules applies recursively, meaning if you
have a module "foo.nix" with
imports = [ ./bar.nix ];
then setting
disabledModules = [ "foo.nix" ];
will disable both "foo.nix" and "bar.nix", whereas previously only
"foo.nix" would be disabled.
This change along with https://github.com/NixOS/nixpkgs/pull/61570 allows
modules to be fully disabled even when they have some `mkRenamedOption`
imports.
Previously when this function was called without a value coercible to a
string it would throw an error instead of returning false. Now it does.
As a result this now allows the use of a type like `either path attrs`
without it erroring out when a definition is an attribute set.
The warning about there not being a isPath primop was removed because
this is not the case anymore, there is builtins.isPath. But also there
always was `builtins.typeOf x == "path"` that could've been used
instead. However the path type now stands for more than just path types,
but absolute paths in general.
If I understand correctly, the problem isn't so much that you're assigning to
that top-level attribute, but that the assignment to the attribute (or any
child of the attribute) introduces the 'config' object and prevents 'lifting'
all settings to a generated 'config' object.
This reverts commit eec83d41e3.
This broke hydra evaluation because with this commit submodule values
are allowed to be paths, however the certmgr module uses `either
(submodule ...) path` in its type, meaning it already used paths for
something else which would now be interpreted as a submodule.
This adds a new utility to intelligently convert Nix records to
command line options to reduce boilerplate for simple use cases and to
also reduce the likelihood of malformed command lines
`pipe` is a useful operator for creating pipelines of functions.
It works around the usual problem of e.g. string operations becoming
deeply nested functions.
In principle, there are four different ways this function could be
written:
pipe val [ f1 .. fn ]
pipe val [ fn .. f1 ]
compose [ f1 .. fn ] val
compose [ fn .. f1 ] val
The third and fourth form mirror composition of functions, they would
be the same as e.g. `(f1 << f2 << f3 .. << fn) val`.
However, it is not clear which direction the list should have (as one
can see in the second form, which is the most absurd.
In order not to confuse users, we decide for the most “intuitive”
form, which mirrors the way unix pipes work (thus the name `pipe`).
The flow of data goes from left to right.

Remove the "version" parameter in order to make it more widely
available.
Starts making some kernel configuration helpers available.
The intent is to be able to better build and check the linux kernel
configuration.
We don't want to ignore config that can mess up machines. In general
this should always fail evaluation, as you think you are changing
behaviour and don't, which can easily create run-time errors we can
catch early.
Previously mkRemovedOptionModule would only show the replacement
instructions when the removed option was *defined*. With this change, it
also does so when an option is *used*.
This is essential for options that are only intended to be used such as
`security.acme.directory`, whose replacement instructions would never
trigger without this change because almost everybody only uses the
option and isn't defining it.
