ocamlformat 0.21.0 · OCaml Package

0.21.0 (2022-02-25)

Bug fixes

Add missing parentheses around variant class arguments (#1967, @gpetiot)
Fix indentation of module binding RHS (#1969, @gpetiot)
Fix position of := when assignment-operator=end-line (#1985, @gpetiot)
Fix position of comments attached to constructor decl (#1986, @gpetiot)
Do not wrap docstrings, wrap-comments should only impact non-documentation comments, wrapping invalid docstrings would cause the whole file to not be formatted (#1988, @gpetiot)
Do not break between 2 module items when the first one has a comment attached on the same line. Only a comment on the next line should induce a break to make it clear to which element it is attached to (#1989, @gpetiot)
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).
Remove incorrect parentheses around polymorphic type constraint (#2002, @gpetiot)
Handle cases where an attribute is added to a bind expression, e.g. (x >>= (fun () -> ())) [@a] (#2013, @emillon)
Fix indentation of constraints of a package type pattern (#2025, @gpetiot)

Changes

More expressions are considered "simple" (not inducing a break e.g. as an argument of an application):
- Variants with no argument (#1968, @gpetiot)
- Empty or singleton arrays/lists (#1943, @gpetiot)
Print odoc code block delimiters on their own line (#1980, @gpetiot)
Make formatting of cons-list patterns consistent with cons-list expressions, (::) operators are aligned when possible, comments position also improved (#1983, @gpetiot)
Apply 'sequence-style' to add a space before ';;' between toplevel items, consistently with the formatting of ';' in sequences (#2004, @gpetiot)

New features

Format toplevel phrases and their output (#1941, @Julow, @gpetiot). This feature is enabled with the flag --parse-toplevel-phrases. Toplevel phrases are supported when they are located in doc-comments blocks and cinaps comments. Whole input files can also be formatted as toplevel phrases with the flag --repl-file.

RPC

ocamlformat-rpc-lib is now functorized over the IO (#1975, @gpetiot). Now handles Csexp.t types instead of Sexplib0.Sexp.t.
RPC v2 (#1935, @panglesd): Define a 'Format' command parameterized with optionnal arguments to set or override the config and path, to format in the style of a file.
Prevent RPC to crash on version mismatch with .ocamlformat (#2011, @panglesd, @Julow)

0.20.1 (2021-12-13)

New features

Update to odoc-parser 1.0.0 (#1843, @Julow). New syntax: code blocks can carry metadata, e.g.: {@ocaml kind=toplevel env=e1[ code ]}

- No functional changes are expected.
- Cherry picked commits: 219dc1e3a4614041e1bc5428d003c0af4e, 9e453b0ef87124e33827ee2423289deef8, 7ad1e575ffa4ce3022c71daba39954d3b9, eb49db6772a9adabe611982000465d0ad7, dc79052a085950cd88fdef0843f665a029, c06c544e21bd65b726cde8fee0f78a6248, ce94d2fa50ff276b5782070375a0b30ba1

0.15.0 (2020-08-06)

Changes

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

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

Bug fixes

0.14.3 (2020-07-22)

Changes

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:
- #1386 - Update opam metadata
- #1396 - Add compatibility with base.v0.14.0
- #1399 - Allow stdio.v0.14

0.14.2 (2020-05-11)

Changes

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) (Josh Berdine, Jules Aguillon, Guillaume Petiot)

This reverts changes introduced in 0.14.1 (#1335) and 0.14.0 (#1012).

0.14.1 (2020-04-14)

Changes

The default for doc-comments is changed to after (#1335) (Jules Aguillon) This reverts a change introduced in 0.14.0 (#1012).
Revert deprecation of the doc-comments option (#1331) (Jules Aguillon) This reverts a change introduced in 0.14.0 (#1293).

0.14.0 (2020-04-02)

New features

Add an option --format-invalid-files to print unparsable parts of the input as verbatim text. This feature is still experimental. (#1026) (Guillaume Petiot)
Support multi-indices extended indexing operators (#1279, #1277) (Jules Aguillon, Guillaume Petiot) This feature has been added in OCaml 4.10.0
Handle OCaml 4.10.0 AST (#1276) (Guillaume Petiot)
Preserve functor syntax for consistency (#1312) (Guillaume Petiot) 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.

Changes

Add the option doc-comments-val=before|after (#1012) (Jules Aguillon) 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) (Jules Aguillon) 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) (Craig Ferguson)

Bug fixes

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

- extensions and eval items (#1230) (Jules Aguillon) eg. the expression [%ext (() [@attr])] or the structure item (() [@attr]) ;;
- let _ = ... constructs (#1244) (Etienne Millon)
Fix some bugs related to comments:
- after a function on the rhs of an infix (#1231) (Jules Aguillon) eg. the comment in (x >>= fun y -> y (* A *)) would be dropped
- in module unpack (#1309) (Jules Aguillon) eg. in the module expression module M = (val x : S (* A *))

Remove unecessary parentheses in the argument of indexing operators (#1280) (Jules Aguillon)
Retain attributes on various AST nodes:
- field set expressions, e.g. (a.x <- b) [@a] (#1284) (Craig Ferguson)
- instance variable set expressions, e.g. (a <- b) [@a] (#1288) (Craig Ferguson)
- indexing operators, e.g. (a.(b)) [@a] (#1300) (Craig Ferguson)
- sequences, e.g. (a; b) [@a] (#1291) (Craig Ferguson)
Avoid unnecessary spacing after object types inside records and polymorphic variants, e.g. {foo : < .. > [@a]} and { foo : < .. > } (#1296) (Craig Ferguson)
Fix missing parentheses around tuples with attributes. (#1301) (Craig Ferguson) 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) (Craig Ferguson)
Fix crash on the expression (0).*(0) (#1304) (Jules Aguillon) It was formatting to 0.*(0) which parses as an other expression.
Preserve empty doc-comments syntax. (#1311) (Guillaume Petiot) Previously (**) would be formatted to (***).
Do not crash when a comment contains just a newline (#1290) (Etienne Millon)
Handle lazy patterns as arguments to class (#1289) (Etienne Millon)
Preserve cinaps comments containing unparsable code (#1303) (Jules Aguillon) 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) (Guillaume Petiot)
Add missing parentheses around OR-patterns with attributes (#1317) (Guillaume Petiot)
Fix spacing inside parens for symbols when the spacing was handled by the englobing exp (#1316) (Guillaume Petiot)
Fix invalid (unparsable) docstrings (#1315) (Guillaume Petiot) 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) (Craig Ferguson)

Changes

Set "conventional" as the default profile (#1060) (Guillaume Petiot) 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) (Jules Aguillon) 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) (Guillaume Petiot) 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) (Guillaume Petiot) 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) (Jules Aguillon) Previously, begin/end keywords around if-then-else branches were turned into parentheses.

New features

Give a hint when warning 50 is raised (#1111) (Guillaume Petiot)
Add a message when a config value is removed (#1089) (Etienne Millon) Explain what replaces removed options and avoid printing a parsing error.
Implement sequence-blank-line=preserve-one for let bindings (#1077) (Jules Aguillon) 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) (Jules Aguillon) 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) (Guillaume Petiot)
Parse code in docstrings (#941) (Guillaume Petiot) Format OCaml code in cinaps-style comments (*$ code *) and code blocks in documentation comments (** {[ code ]} *).
Parse documentation comments with Odoc (#721) (Jules Aguillon) Formatting of documentation comments is more robust and support newer Odoc syntaxes. Internally, Odoc replaces Octavius as the documentation parser.
