* | lib.trivial.warnIf: initAlyssa Ross2021-04-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* lib: toHex -> toHexString & toBase -> toBaseDigitsBas van Dijk2020-07-20
| | | | This makes the type of these functions more apparent from the name.
* lib: add the toHex and toBase utility functionsBas van Dijk2020-07-20
| | | | | | | | | | | | | | | | | | | | | | | | `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 symlinkFranz Pletz2020-01-20
| | | | | | | | | | | Before c9214c394b248e1f26e45dbe1be2bd82363af3a6 and 9d396d2e426b9a765de0b8999aa214f1259633e6 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-worktreeelseym2020-01-10
| | | | | | | | | | | | | | 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
* lib/trivial: add `pipe` functionProfpatsch2019-10-21
| | | | | | | | | | | | | | | | | | | | | | | | | | `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 attributesMaximilian Bosch2018-04-28
| | | | | | | | | | | | | | | 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 referencesMaximilian Bosch2018-04-28
| | | | | | The logic regarding the generated `.version-suffix` file is already defined in `lib/trivial.nix` and shouldn't be duplicated in `nixos/version`.

* Convert libs to a fixed-pointGraham Christensen2017-09-16

I made this while exploring being able to swap out docFn with a stub in #2305, to avoid functor performance problems. I don't know if that is going to move forward (or if it is a problem or not,) but after doing all this work figured I'd put it up anyway :) Two notable advantages to this approach: 1. when a lib inherits another lib's functions, it doesn't automatically get put in to the scope of lib 2. when a lib implements a new obscure functions, it doesn't automatically get put in to the scope of lib Using the test script (later in this commit) I got the following diff on the API: + diff master fixed-lib 11764a11765,11766 > .types.defaultFunctor > .types.defaultTypeMerge 11774a11777,11778 > .types.isOptionType > .types.isType 11781a11786 > .types.mkOptionType 11788a11794 > .types.setType 11795a11802 > .types.types This means that this commit _adds_ to the API, however I can't find a way to fix these last remaining discrepancies. At least none are _removed_. Test script (run with nix-repl in the PATH): #!/bin/sh set -eux repl() { suff=${1:-} echo "(import ./lib)$suff" \ | nix-repl 2>&1 } attrs_to_check() { repl "${1:-}" \ | tr ';' $'\n' \ | grep "\.\.\." \ | cut -d' ' -f2 \ | sed -e "s/^/${1:-}./" \ | sort } summ() { repl "${1:-}" \ | tr ' ' $'\n' \ | sort \ | uniq } deep_summ() { suff="${1:-}" depth="${2:-4}" depth=$((depth - 1)) summ "$suff" for attr in $(attrs_to_check "$suff" | grep -v "types.types"); do if [ $depth -eq 0 ]; then summ "$attr" | sed -e "s/^/$attr./" else deep_summ "$attr" "$depth" | sed -e "s/^/$attr./" fi done } ( cd nixpkgs #git add . #git commit -m "Auto-commit, sorry" || true git checkout fixed-lib deep_summ > ../fixed-lib git checkout master deep_summ > ../master ) if diff master fixed-lib; then echo "SHALLOW MATCH!" fi ( cd nixpkgs git checkout fixed-lib repl .types )
