currentSystem function, but false if it does.

lib: fix functionArgs for functors

Alyssa Ross 81e1e68eaf lib.trivial.warnIf: init
It's a common pattern in Nixpkgs to want to emit a warning in certain
cases, but not actually change behaviours.

This is often expressed as either
	if cond then lib.warn "Don't do that thing" x else x
Or
	(if cond then lib.warn "Don't do that thing" else lib.id) x

Neither of which really expresses the intent here, because it looks
like 'x' is being chosen conditionally.

To make this clearer, I introduce a "warnIf" function, which makes it
clear that the only thing being affected by the condition is whether
the warning is generated, not the value being returned.

Bas van Dijk 6e7822b8f3 lib: toHex -> toHexString & toBase -> toBaseDigits
This makes the type of these functions more apparent from the name.
2020-07-20 13:14:19 +02:00
Bas van Dijk 00022fbeda lib: add the toHex and toBase utility functions
`toHex` converts the given positive integer to a string of the hexadecimal
representation of that integer. For example:

```
toHex 0 => "0"

toHex 16 => "10"

toHex 250 => "FA"
```

`toBase base i` converts the positive integer `i` to a list of it
digits in the given `base`. For example:

```
toBase 10 123 => [ 1 2 3 ]

toBase 2 6 => [ 1 1 0 ]

toBase 16 250 => [ 15 10 ]
```

nixos/version: fix case where .git is a symlink
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.

lib.commitIdFromGitRepo: support git-worktree
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

Profpatsch 8252861507 lib/trivial: add pipe function
`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.

treewide: rename version attributes
As suggested in https://github.com/NixOS/nixpkgs/pull/39416#discussion_r183845745
the versioning attributes in `lib` should be consistent to
`nixos/version` which implicates the following changes:

* `lib.trivial.version` -> `lib.trivial.release`
* `lib.trivial.suffix` -> `lib.trivial.versionSuffix`
* `lib.nixpkgsVersion` -> `lib.version`

As `lib.nixpkgsVersion` is referenced several times in `NixOS/nixpkgs`,
`NixOS/nix` and probably several user's setups. As the rename will cause
a notable impact it's better to keep `lib.nixpkgsVersion` as alias with
a warning yielded by `builtins.trace`.

lib: deduplicate version/suffix references

`nixos/version`.
