3.0.0

Added

  • Different levels of --quiet by repeating the -q flag,
    which makes Vim users have a better formatting experience by using :%!alejandra -qq to format the current buffer,
    specially when the file has syntax errors.

  • The possibility for companies to promote their business
    by placing an add at the end of Alejandra's terminal output, and thank you messages for the sponsors of the project.

    You can obtain this benefits in @kamadorueda's sponsor page.

  • Thank you messages for the different people
    who have helped improving Alejandra.

Changed

  • Now big files are formatted first,
    making faster the formatting process
    when using many threads and
    when formatting a big file is slower
    than formatting all the other smaller files in the repository.
    For instance in Nixpkgs.
  • The CLI was simplified,
    removing the elements that people find less useful
    and polishing those that people use the most.
    The screen is not cleared anymore.
  • Upgraded dependencies to its latest version.

Fixed

  • The name displayed in the CLI application used to be alejandra_cli,
    now it is Alejandra.
  • Typos here and there.

2.0.0

Added

  • A Style Guide,
    explaining why certain decisions were taken
    and why they are optimal
    from a productive Nix hacker point of view.

    This guide is a work in progress,
    but the aim is that it eventually documents
    all of the aspects of the Nix language,
    so that we all have the peace of mind
    that comes from knowing that the style in Alejandra
    is the way it is for a reason.

  • Integration guides for: Neovim and GNU Emacs.

  • Published Alejandra as a crate,
    and added API documentation
    so other tools and integrations can be built in top of it.

Changed

  • Now running: $ alejandra - formats stdin,
    as POSIX
    suggests.

  • Comments are now indented by a multiple of 2
    issues/294:

    Previously
    (notice how some lines are indented with 3 and 5 spaces):

    /*
 Bla bla bla.

 More bla:
   - Bla bla
   - Bla
 */
123

    Now (all lines are indented to 2 and 4 spaces):

    /*
Bla bla bla.

More bla:
  - Bla bla
  - Bla
*/
123

    This makes it easier to write comments on major code editors,
    where a <TAB> (or <Shift>+<Tab>)
    moves the cursor/content to the next multiple of 2,
    and so indenting the comment contents
    to an odd number of spaces (like 3, 5, 7)
    is uncomfortable and unproductive.

    This change also allows cooperation
    with other tools
    like EditorConfig,
    to further exercise good practices over a codebase.

  • Updated dependencies to its latest version.

Fixed

  • Empty lines in comments are now effectively empty,
    avoiding git from warning about extra whitespace:
    issues/314.

1.2.0

Added

  • A new i686-linux system to the flake.
  • apps.${system}.default to the Flake
    so that newer versions of Nix
    understand this instead of defaultApp.${system}.

Fixed

  • A typo in the documentation where aarch64-linux appeared twice
    and aarch64-darwin didn't.

Added

  • NixOS installation instructions

Changed

  • The indentation for function applications was improved,
    so that indentation is now correct to the human eye in all cases:

    -  name2 = function arg {
-    asdf = 1;
-  }
-  argument;
+  name2 =
+    function arg {
+      asdf = 1;
+    }
+    argument;

  • String interpolations ("${something}")
    now follow the same logic as parentheses ((something)),
    since ultimately, they are the same family of elements.

  • Parentheses handling logic was rewritten
    and by extension string interpolations as well.

    - (
-   self: super: {
-     # ...
-   }
- )
+ (self: super: {
+   # ...
+ })
    -      builtins.map (
-        pkg: {
-          name = "alejandra-${pkg.stdenv.targetPlatform.config}";
-          value = pkg;
-        }
-      )
+      builtins.map (pkg: {
+        name = "alejandra-${pkg.stdenv.targetPlatform.config}";
+        value = pkg;
+      })
    -      (
-        fenix.combine [
-          fenix.latest.rustc
-          fenix.latest.toolchain
-          fenix.targets."wasm32-unknown-unknown".latest.rust-std
-        ]
-      )
+      (fenix.combine [
+        fenix.latest.rustc
+        fenix.latest.toolchain
+        fenix.targets."wasm32-unknown-unknown".latest.rust-std
+      ])
       pkgs.writeText "other-modules.json"
   (l.toJSON
-  (l.mapAttrs
-  (pname: subOutputs: let
-    pkg = subOutputs.packages."${pname}".overrideAttrs (old: {
-      buildScript = "true";
-      installMethod = "copy";

-  outputs.subPackages))
+    (l.mapAttrs

+          pkg = subOutputs.packages."${pname}".overrideAttrs (old: {
+            buildScript = "true";
+            installMethod = "copy";
+          });
+        in
+          "${pkg}/lib/node_modules/${pname}/node_modules")
+      outputs.subPackages))
    -  (with a;
-  /*
-   comment
-   */
-  with b;
-  with c; {
-    a = 1;
-    b = 2;
-  })
+  (with a;
+    /*
+      comment
+      */
+    with b;
+    with c; {
+      a = 1;
+      b = 2;
+    })

    In some cases it's possible to insert a newline after the
    opening element (either ( or ${) to force a tall formatting.

Removed

  • A few internal position counters, nothing visible from the outside.
  • The new features cost a little of runtime speed,
    but anyway we are still pretty fast. ⚡

0.7.0

Added

  • Inline comments support in binary operators: 
    -      ++
-      # subsections go last
+      ++ # subsections go last
  • Inline comments support in with and assert expressions: 
    -  assert (libXft != null) -> libpng != null;
-  # probably a bug
-  assert stdenv.isDarwin -> libXaw != null;
-  # fails to link otherwise
+  assert (libXft != null) -> libpng != null; # probably a bug
+
+  assert stdenv.isDarwin -> libXaw != null; # fails to link otherwise
+
  • Inline comments support for if-then-else expressions: 
                    if y ? ${a}
-                then v x.${a} y.${a}
-                # both have attr, use merge func
-                else x.${a}
-              # only x has attr
+                then v x.${a} y.${a} # both have attr, use merge func
+                else x.${a} # only x has attr
  • Inline comments support for inherit expressions: 
        inherit
      (callPackage ../development/tools/ocaml/ocamlformat {})
-      ocamlformat
-      # latest version
+      ocamlformat # latest version
       ocamlformat_0_11_0
  • Inline comments support for parenthesis expressions: 
    -        || (
-          # Accept {} for tests that are unsupported
+        || ( # Accept {} for tests that are unsupported
          isDerivation x
          && x ? meta.timeout
        );

Changed

  • Linux binaries now use mimalloc
    to provide much better performance when formatting Nixpkgs:

    • x86_64-unknown-linux-gnu, 1.3x faster,
      from 0m10.639s to 0m8.381s

    • x86_64-unknown-linux-musl, 15.8x faster,
      from 2m32.686s to 0m9.642s

    • On QEMU aarch64-unknown-linux-musl,
      4.6x faster,
      from 5m26s to 1m10s

    • On QEMU armv6l-unknown-linux-musleabihf,
      1.05x faster,
      from 8m7s to 7m41s

    • On QEMU armv7l-unknown-linux-musleabihf,
      1.15x faster,
      from 5m54s to 5m7s

    • On QEMU i686-unknown-linux-musl,
      1.07x faster,
      from 2m44s to 2m33s

  • After profiling the code as suggested by
    nnethercote's perf-book
    one critical path of Alejandra was identified an optimized,
    yielding huge performance boosts:

    • x86_64-unknown-linux-gnu, 2.5x faster,
      from 0m8.381s to 0m3.410s

    • x86_64-unknown-linux-musl, 2.3x faster,
      from 0m9.642s to 0m4.134s

    • On QEMU aarch64-unknown-linux-musl,
      2.4x faster,
      from 1m10s to 0m29s

    • On QEMU armv6l-unknown-linux-musleabihf,
      1.85x faster,
      from 7m41s to 4m8.399s

    • On QEMU armv7l-unknown-linux-musleabihf,
      1.88x faster,
      from 5m7s to 2m42.595s

    • On QEMU i686-unknown-linux-musl,
      1.65x faster,
      from 2m33s to 1m32.671s

    In general this is an algorithmic improvement
    and therefore the following platforms should be faster as well
    by a similar ratio
    (not measured):

    • aarch64-apple-darwin
    • x86_64-apple-darwin

  • A --threads flag, so you can pick how many formatting threads to spawn.
    Defaults to the number of logical CPUs in your system.

  • Position counters were improved to offer an extra 1.13x speedup.
