• Preserve position of comments attached to the last node of a subtree (#1667, @gpetiot)

• Do not override the values of the following non-formatting options when a profile is set: comment-check, disable, max-iters, ocaml-version, and quiet (#1995, @gpetiot).

0.15.1 (2020-11-02)

Internal

• Use ppxlib instead of ocaml-migrate-parsetree 1.x. (#1482, @emillon)

  • No functional changes are expected.

  • Cherry picked commits: 219dc1e3a4614041e1bc5428d003c0af4e, 9e453b0ef87124e33827ee2423289deef8, 7ad1e575ffa4ce3022c71daba39954d3b9, eb49db6772a9adabe611982000465d0ad7, dc79052a085950cd88fdef0843f665a029, c06c544e21bd65b726cde8fee0f78a6248, ce94d2fa50ff276b5782070375a0b30ba1

0.15.0 (2020-08-06)

Changed

• Do not break inline elements such as {i blah} in docstrings (#1346, @jberdine)

• Distinguish hash-getter from hash-comparison infix operators. Operators of the form #**# or #**. where ** can be 0 or more operator chars are considered getter operators and are not surrounded by spaces, as opposed to regular infix operators (#1376, @gpetiot)

• Type constraint on return type of functions is now always printed before the function body (#1381, #1397, @gpetiot)

Fixed

• Restore previous functionality for pre-post extension points (#1342, @jberdine)

• Fix extra break before function body of a fun (#1343, @jberdine)

• Indent further args of anonymous functions (#1440, @gpetiot)

• Do not clear the emacs *compilation* buffer on successful reformat (#1350, @jberdine)

• Fix disabling with attributes on OCaml < 4.08 (#1322, @emillon)

• Preserve unwrapped comments by not adding artificial breaks when wrap-comments=false and ocp-indent-compat=true are set to avoid interfering with ocp-indent indentation. (#1352, @gpetiot)

• Break long literal strings at the margin (#1367, @gpetiot)

• Break after a multiline argument in an argument list (#1360, @gpetiot)

• Remove unnecessary parens around object (#1379, @gpetiot)

• Fix placement of comments on constants (#1383, @gpetiot)

• Do not escape arguments of some Odoc tags (#1391, 1408, @gpetiot, @Julow). The characters []{} must not be escaped in the arguments of @raise, @author, @version and others.

• Fix missing open line between multi-line let-binding with poly-typexpr (#1372, @jberdine)

• Remove trailing space after expression when followed by an attribute and break before attributes attached to multi-line phrases (#1382, @gpetiot)

• Do not add a space to minimal comments (* *), (** *) and (*$ *) (#1407, @gpetiot)

• Fix attributes position in labelled arguments type (#1434, @gpetiot)

• Add missing parens around type annotation in anonymous function (#1433, @gpetiot)

• Fix alignment of 'then' keyword in parenthesised expression (#1421, @gpetiot)

Added

• Support quoted extensions (added in ocaml 4.11) (#1405, @gpetiot)

• Recognise eliom file extensions (#1430, @jrochel)

0.14.3 (2020-07-22)

Changed

• No functional changes from 0.14.2. The goal of this release is to be compatible with base and stdio v0.14.0.

• Backport the following PRs:

  • Update opam metadata (#1386)

  • Add compatibility with base.v0.14.0 (#1396)

  • Allow stdio.v0.14 (#1399)

0.14.2 (2020-05-11)

Changed

• Merge doc-comments-val option with doc-comments. The placement of documentation comments on val and external items is now controled by doc-comments.

  • doc-comments=after becomes doc-comments=after-when-possible to take into account the technical limitations of ocamlformat;

  • doc-comments=before is unchanged;

  • doc-comments-val is now replaced with doc-comments. To reproduce the former behaviors

    • doc-comments=before + doc-comments-val=before: now use doc-comments=before;

    • doc-comments=before + doc-comments-val=after: now use doc-comments=before-except-val;

    • doc-comments=after + doc-comments-val=before: this behavior did not make much sense and is not available anymore;

    • doc-comments=after + doc-comments-val=after: now use doc-comments=after-when-possible. (#1358, @jberdine, @Julow, @gpetiot). This reverts changes introduced in 0.14.1 (#1335) and 0.14.0 (#1012).

0.14.1 (2020-04-14)

Changed

• The default for doc-comments is changed to after (#1335, @Julow). This reverts a change introduced in 0.14.0 (#1012).

• Revert deprecation of the doc-comments option (#1331, @Julow). This reverts a change introduced in 0.14.0 (#1293).

0.14.0 (2020-04-02)

Added

• Add an option --format-invalid-files to print unparsable parts of the input as verbatim text. This feature is still experimental. (#1026, @gpetiot)

• Support multi-indices extended indexing operators (#1279, #1277, @Julow, @gpetiot). This feature has been added in OCaml 4.10.0

• Handle OCaml 4.10.0 AST (#1276, @gpetiot)

• Preserve functor syntax for consistency (#1312, @gpetiot). Previously both functor syntax: module M = functor (K : S) -> struct end and module M (K : S) = struct end would be formatted as the latter, the original syntax is now preserved.

Changed

• Add the option doc-comments-val=before|after (#1012, @Julow). This option set the placement of documentation comment on val and external only. It is set to after by default.

• The default for doc-comments is changed from after to before (#1012, #1325, @Julow). This affects both conventional (default) and ocamlformat profiles.

• Some options are now deprecated:

  • doc-comments (#1293, #1012). This option depends on a flawed heuristic. It is replaced by doc-comments-val for val and external declarations. There is no equivalent to this option in the general case.

  • escape-chars, escape-strings and extension-sugar (#1293). These options are rarely used and their default behavior is considered to be the right behavior.

• Add space between row_field attributes and the label or arguments, to be consistent with the non-polymorphic case. (#1299, @CraigFe)

Fixed

• Fix missing parentheses around let open (#1229, @Julow). eg. M.f (M.(x) [@attr]) would be formatted to M.f M.(x) [@attr], which would crash OCamlformat

• Remove unecessary parentheses with attributes in some structure items:

  • extensions and eval items (#1230, @Julow). eg. the expression [%ext (() [@attr])] or the structure item (() [@attr]) ;;

  • let _ = ... constructs (#1244, @emillon)

• Fix some bugs related to comments:

  • after a function on the rhs of an infix (#1231, @Julow). eg. the comment in (x >>= fun y -> y (* A *)) would be dropped

  • in module unpack (#1309, @Julow). eg. in the module expression module M = (val x : S (* A *))

• Fix formatting of empty signature payload [%a:] (#1236, @emillon)

• Fix parenthesizing when accessing field of construct application (#1247, @gpetiot)

• Fix formatting of attributes on object overrides {< >} (#1238, @emillon)

• Fix attributes on coercion (#1239, @emillon)

• Fix formatting of attributes on packed modules (#1243, @emillon)

• Fix parens around binop operations with attributes (#1252, #1306, @gpetiot, @CraigFe)

• Remove unecessary parentheses in the argument of indexing operators (#1280, @Julow)

• Retain attributes on various AST nodes:

  • field set expressions, e.g. (a.x <- b) [@a] (#1284, @CraigFe)

  • instance variable set expressions, e.g. (a <- b) [@a] (#1288, @CraigFe)

  • indexing operators, e.g. (a.(b)) [@a] (#1300, @CraigFe)

  • sequences, e.g. (a; b) [@a] (#1291, @CraigFe)

• Avoid unnecessary spacing after object types inside records and polymorphic variants, e.g. {foo : < .. > [@a]} and { foo : < .. > } (#1296, @CraigFe)

• Fix missing parentheses around tuples with attributes. (#1301, @CraigFe). Previously, f ((0, 0) [@a]) would be formatted to f (0, 0) [@a], crashing OCamlformat.

• Avoid emitting >] when an object type is contained in an extension point or attribute payload (#1298, @CraigFe)

• Fix crash on the expression (0).*(0) (#1304, @Julow). It was formatting to 0.*(0) which parses as an other expression.

• Preserve empty doc-comments syntax. (#1311, @gpetiot). Previously (**) would be formatted to (***).

• Do not crash when a comment contains just a newline (#1290, @emillon)

• Handle lazy patterns as arguments to class (#1289, @emillon)

• Preserve cinaps comments containing unparsable code (#1303, @Julow). Previously, OCamlformat would fallback to the "wrapping" logic, making the comment unreadable and crashing in some cases.

• Fix normalization of attributes, fixing the docstrings in attributes (#1314, @gpetiot)

• Add missing parentheses around OR-patterns with attributes (#1317, @gpetiot)

• Fix spacing inside parens for symbols when the spacing was handled by the englobing exp (#1316, @gpetiot)

• Fix invalid (unparsable) docstrings (#1315, @gpetiot). When parsing a comment raises an error in odoc, it is printed as-is.

• Fix parenthesizing of optional arguments rebound to non-variables, e.g. let f ?a:(A) = () rather than the unparsable let f ?a:A = () (#1305, @CraigFe)

0.13.0 (2020-01-28)

Added

• Add an option --margin-check to emit a warning if the formatted output exceeds the margin (#1110, @gpetiot)

• Preserve comment indentation when wrap-comments is unset (#1138, #1159, @Julow)

• Improve error messages (#1147, @Julow)

• Display standard output in the emacs plugin even when ocamlformat does not fail (#1189, @gpetiot)

Removed

• Remove ocamlformat_reason (#254, #1185, @emillon). This tool has never been released to opam, has no known users, and overlaps with what refmt can do.

• Remove ocamlformat-diff (#1205, @gpetiot). This tool has never been released to opam, has no known users, and overlaps with what merge-fmt can do.

Packaging

• Work with base v0.13.0 (#1163, @Julow)

• Fix hint when using break-separators=after-and-docked (#1130, @gretay-js)

0.12 (2019-11-04)

Changed

• Set "conventional" as the default profile (#1060, @gpetiot). This new profile is made to better match the most used style and is encouraged. To continue using the previous default, use profile = ocamlformat in your .ocamlformat.

• CLI: Allow both values of boolean options (#1062, @Julow). Now, both --opt and --no-opt` are available on the CLI for any boolean option "opt". Previously, only one of them were available depending on the default value.

• Auto mode for break-string-literals (#1057, @gpetiot). wrap, newlines and newlines-and-wrap values of break-string-literals are removed. auto replaces them, it is equivalent to newlines-and-wrap.

• Dock collection brackets (#1014, @gpetiot). after-and-docked value of break-separators is removed and is replaced by a new dock-collection-brackets option.

• Preserve begin and end keywords in if-then-else (#978, @Julow). Previously, begin/end keywords around if-then-else branches were turned into parentheses.

Added

• Give a hint when warning 50 is raised (#1111, @gpetiot)

• Add a message when a config value is removed (#1089, @emillon). Explain what replaces removed options and avoid printing a parsing error.

• Implement sequence-blank-line=preserve-one for let bindings (#1077, @Julow). Preserve a blank line after let .. in when sequence-blank-line set to preserve-one. Previously, only blank lines after ; could be preserved.

• Parse toplevel directives (#1020, @Julow). Allow #directives in .ml files. Previously, files containing a directive needed to be parsed as "use file". The "use file" mode is removed and --use-file is now the same as --impl.

• Don't require --name, require kind, forbid --inplace, allow --check, make --enable-outside-detected-project implicit when reading from stdin (#1018, @gpetiot)

• Parse code in docstrings (#941, @gpetiot). Format OCaml code in cinaps-style comments (*$ code *) and code blocks in documentation comments (** {[ code ]} *).

• Parse documentation comments with Odoc (#721, @Julow). Formatting of documentation comments is more robust and support newer Odoc syntaxes. Internally, Odoc replaces Octavius as the documentation parser.
