Releases: ocaml-ppx/ocamlformat
0.27.0
CHANGES:
Highlight
-
* Support OCaml 5.2 syntax (#2519, #2544, #2590, #2596, #2621, #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 (#2609, #2610, #2611, #2622, #2623, #2562, #2624, #2625, #2627, @Julow, @Zeta611)
This adds support for effect patterns, short functor type arguments and utf8
identifiers.
To format code using the neweffect
syntax, add this option to your
.ocamlformat
:ocaml-version = 5.3
-
Documentation comments are now formatted by default (#2390, @Julow)
Use the optionparse-docstrings = false
to restore the previous behavior. -
* Consistent indentation of polymorphic variant arguments (#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))
Added
-
Improve the emacs plugin (#2577, #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
(#2521, @henrytill)
to control the indentation of thefun
in:let f = fun foo -> bar
-
Added back the flag
--disable-outside-detected-project
(#2439, @gpetiot)
It was removed in version 0.22.
Changed
-
* Consistent formatting of comments (#2371, #2550, @Julow)
This is mostly an internal change but some comments might be formatted differently. -
* Improve formatting of type constraints with type variables (#2437, @gpetiot)
For example:let f : type a b c. a -> b -> c = ...
-
* Improve formatting of functor arguments (#2505, @Julow)
This also reduce the indentation of functor arguments with long signatures. -
Improvements to the Janestreet profile (#2445, #2314, #2460, #2593, #2612, @Julow, @tdelvecchio-jsc)
-
* Undo let-bindings and methods normalizations (#2523, #2529, @gpetiot)
This remove the rewriting of some forms of let-bindings and methods:let f x = (x : int)
is no longer rewritten intolet f x : int = x
let f (type a) (type b) ...
is no longer rewritten intolet f (type a b) ...
let f = fun x -> ...
is no longer rewritten intolet f x = ...
-
* The
break-colon
option is now taken into account for method type constraints (#2529, @gpetiot) -
* Force a break around comments following an infix operator (fix non-stabilizing comments) (#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 (#2471, #2503, #2506, #2540, #2541, #2592, #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 (#2247, #2459, #2551, #2564, #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 formatopen[@attr] M
asopen M [@@attr]
. -
Remove trailing space inside a wrapping empty signature (#2443, @Julow)
-
* Consistent break after string constant argument (#2453, @Julow)
-
* Fix cinaps comment formatting to not change multiline string contents (#2463, @tdelvecchio-jsc)
-
* Fix the indentation of tuples in attributes and extensions (#2488, @Julow)
-
* Fix weird indentation and line breaks after comments (#2507, #2589, #2606, @Julow)
-
Fix missing parentheses around constraint expressions with attributes (#2513, @alanechang)
-
Fix formatting of type vars in GADT constructors (#2518, @Julow)
-
Fix
[@ocamlformat "disable"]
in some cases (#2242, #2525, @EmileTrotignon)
This caused a bug insideclass type
constructs and when attached to alet ... in
-
Display
a##b
instead ofa ## b
and similarly for operators that start with # (#2580, @v-gb) -
* Fix arrow type indentation with
break-separators=before
(#2598, @Julow) -
Fix missing parentheses around a let in class expressions (#2599, @Julow)
-
Fix formatting of paragraphs in lists in documentation (#2607, @Julow)
-
Avoid unwanted space in references and links text in documentation (#2608, @Julow)
-
* Improve the indentation of attributes in patterns (#2613, @Julow)
-
* Avoid large indentation in patterns after
let%ext
(#2615, @Julow)
