Ocamlformat 0.12

See full changelog

Changes

  • 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.

New features

  • 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.
