0.28.1.2

CHANGES:

• Fixes #10

0.28.1.1

CHANGES:

Highlight

• * Update Odoc's parser to 3.0 (ocaml-ppx#2757, @Julow)
  The indentation of code-blocks containing OCaml code is reduced by 2 to avoid
  changing the generated documentation. The indentation within code-blocks is
  now significative in Odoc and shows up in generated documentation.

Added

• Added option letop-punning (ocaml-ppx#2746, @WardBrian) to control whether
  punning is used in extended binding operators.
  For example, the code let+ x = x in ... can be formatted as
  let+ x in ... when letop-punning=always. With letop-punning=never, it
  becomes let+ x = x in .... The default is preserve, which will
  only use punning when it exists in the source.
  This also applies to let%ext bindings (ocaml-ppx#2747, @WardBrian).

• Support the unnamed functor parameters syntax in module types
  (ocaml-ppx#2755, ocaml-ppx#2759, @Julow)

  module type F = ARG -> S

  The following lines are now formatted as they are in the source file:

  module M : (_ : S) -> (_ : S) -> S = N
  module M : S -> S -> S = N
  (* The preceding two lines are no longer turned into this: *)
  module M : (_ : S) (_ : S) -> S = N

Fixed

• Fix dropped comment in (function _ -> x (* cmt *)) (ocaml-ppx#2739, @Julow)

• * cases-matching-exp-indent=compact does not impact begin end nodes that
  don't have a match inside. (ocaml-ppx#2742, @EmileTrotignon)

  (* before *)
  begin match () with
  | () -> begin
    f x
  end
  end
  (* after *)
  begin match () with
  | () -> begin
      f x
    end
  end

• Ast_mapper now iterates on all locations inside of Longident.t,
  instead of only some.
  (ocaml-ppx#2737, @v-gb)

Internal

• Added information on writing tests to CONTRIBUTING.md (#2838, @WardBrian)

Changed

• indentation of the end keyword in a match-case is now always at least 2. (ocaml-ppx#2742, @EmileTrotignon)

  (* before *)
  begin match () with
  | () -> begin
    match () with
    | () -> ()
  end
  end
  (* after *)
  begin match () with
  | () -> begin
    match () with
    | () -> ()
  

• * use shortcut begin end in match cases and if then else body. (ocaml-ppx#2744, @EmileTrotignon)

  (* before *)
  match () with
  | () -> begin
      match () with
      | () ->
    end
  end
  (* after *)
  match () with
  | () ->
    begin match () with
      | () ->
    end
  end

• * Set the ocaml-version to 5.4 by default (ocaml-ppx#2750, @EmileTrotignon)
  The main difference is that the effect keyword is recognized without having
  to add ocaml-version=5.3 to the configuration.
  In exchange, code that use effect as an identifier must use
  ocaml-version=5.2.

0.27.0.1

CHANGES:

• relax OCaml constraints, compatible with OCaml 5.3

0.27.0

CHANGES:

Highlight

• * Support OCaml 5.2 syntax (ocaml-ppx#2519, ocaml-ppx#2544, ocaml-ppx#2590, ocaml-ppx#2596, ocaml-ppx#2621, ocaml-ppx#2628, @Julow, @EmileTrotignon, @hhugo)
  This includes local open in types, raw identifiers, and the new
  representation for functions.
  This might change the formatting of some functions due to the formatting code
  being completely rewritten.

• Support OCaml 5.3 syntax (ocaml-ppx#2609, ocaml-ppx#2610, ocaml-ppx#2611, ocaml-ppx#2622, ocaml-ppx#2623, ocaml-ppx#2562, ocaml-ppx#2624, ocaml-ppx#2625, ocaml-ppx#2627, @Julow, @Zeta611)
  This adds support for effect patterns, short functor type arguments and utf8
  identifiers.
  To format code using the new effect syntax, add this option to your
  .ocamlformat:

  ocaml-version = 5.3
  

• Documentation comments are now formatted by default (ocaml-ppx#2390, @Julow)
  Use the option parse-docstrings = false to restore the previous behavior.

• * Consistent indentation of polymorphic variant arguments (ocaml-ppx#2427, @Julow)
  Increases the indentation by one to make the formatting consistent with
  normal variants. For example:

    ...
    (* before *)
      (`Msg
        (foo bar))
    (* after *)
      (`Msg
         (foo bar))
  

• Build on OCaml 5.3 (ocaml-ppx#2603, @adamchol, @Julow)

Added

• Improve the emacs plugin (ocaml-ppx#2577, ocaml-ppx#2600, @gridbugs, @thibautbenjamin)
  Allow a custom command to be used to run ocamlformat and add compatibility
  with emacs ocaml tree-sitter modes.

• Added option let-binding-deindent-fun (ocaml-ppx#2521, @henrytill)
  to control the indentation of the fun in:

  let f =
   fun foo ->
    bar
  

• Added back the flag --disable-outside-detected-project (ocaml-ppx#2439, @gpetiot)
  It was removed in version 0.22.

• Support newer Odoc syntax (ocaml-ppx#2631, ocaml-ppx#2632, ocaml-ppx#2633, @Julow)

Changed

• * Consistent formatting of comments (ocaml-ppx#2371, ocaml-ppx#2550, @Julow)
  This is mostly an internal change but some comments might be formatted differently.

• * Improve formatting of type constraints with type variables (ocaml-ppx#2437, @gpetiot)
  For example:

  let f : type a b c.
      a -> b -> c =
    ...
  

• * Improve formatting of functor arguments (ocaml-ppx#2505, @Julow)
  This also reduce the indentation of functor arguments with long signatures.

• Improvements to the Janestreet profile (ocaml-ppx#2445, ocaml-ppx#2314, ocaml-ppx#2460, ocaml-ppx#2593, ocaml-ppx#2612, @Julow, @tdelvecchio-jsc)

• * Undo let-bindings and methods normalizations (ocaml-ppx#2523, ocaml-ppx#2529, @gpetiot)
  This remove the rewriting of some forms of let-bindings and methods:

  • let f x = (x : int) is no longer rewritten into let f x : int = x
  • let f (type a) (type b) ... is no longer rewritten into let f (type a b) ...
  • let f = fun x -> ... is no longer rewritten into let f x = ...

• * The break-colon option is now taken into account for method type constraints (ocaml-ppx#2529, @gpetiot)

• * Force a break around comments following an infix operator (fix non-stabilizing comments) (ocaml-ppx#2478, @gpetiot)
  This adds a line break:

    a
    ||
    (* this comment is now on its own line *)
    b
  

Fixed

• Fix placement of comments in some cases (ocaml-ppx#2471, ocaml-ppx#2503, ocaml-ppx#2506, ocaml-ppx#2540, ocaml-ppx#2541, ocaml-ppx#2592, ocaml-ppx#2617, @gpetiot, @Julow)
  Some comments were being moved or causing OCamlformat to crash.
  OCamlformat refuses to format if a comment would be missing in its output, to avoid loosing code.

• Fix attributes being dropped or moved (ocaml-ppx#2247, ocaml-ppx#2459, ocaml-ppx#2551, ocaml-ppx#2564, ocaml-ppx#2602, @EmileTrotignon, @tdelvecchio-jsc, @Julow)
  OCamlformat refuses to format if the formatted code has a different meaning than the original code, for example, if an attribute is removed.
  We also try to avoid moving attributes even if that doesn't change the original code, for example we no longer format open[@attr] M as open M [@@attr].

• Remove trailing space inside a wrapping empty signature (ocaml-ppx#2443, @Julow)

• Fix extension-point spacing in structures (ocaml-ppx#2450, @Julow)

• * Consistent break after string constant argument (ocaml-ppx#2453, @Julow)

• * Fix cinaps comment formatting to not change multiline string contents (ocaml-ppx#2463, @tdelvecchio-jsc)

• * Fix the indentation of tuples in attributes and extensions (ocaml-ppx#2488, @Julow)

• * Fix weird indentation and line breaks after comments (ocaml-ppx#2507, ocaml-ppx#2589, ocaml-ppx#2606, @Julow)

• * Fix unwanted alignment in if-then-else (ocaml-ppx#2511, @Julow)

• Fix missing parentheses around constraint expressions with attributes (ocaml-ppx#2513, @alanechang)

• Fix formatting of type vars in GADT constructors (ocaml-ppx#2518, @Julow)

• Fix [@ocamlformat "disable"] in some cases (ocaml-ppx#2242, ocaml-ppx#2525, @EmileTrotignon)
  This caused a bug inside class type constructs and when attached to a let ... in

• Display a##b instead of a ## b and similarly for operators that start with # (ocaml-ppx#2580, @v-gb)

• * Fix arrow type indentation with break-separators=before (ocaml-ppx#2598, @Julow)

• Fix missing parentheses around a let in class expressions (ocaml-ppx#2599, @Julow)

• Fix formatting of paragraphs in lists in documentation (ocaml-ppx#2607, @Julow)

• Avoid unwanted space in references and links text in documentation (ocaml-ppx#2608, @Julow)

• * Improve the indentation of attributes in patterns (ocaml-ppx#2613, @Julow)

• * Avoid large indentation in patterns after let%ext (ocaml-ppx#2615, @Julow)
