See full changelog

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)
