Added

• Display OCaml warnings in mdx-error blocks (#293, @gpetiot)

Fixed

• Show exceptions in the correct order (#332, @talex5)

1.9.0

Added

• Add a new dune-gen subcommand that generates testing code for Dune to build and run with the new mdx stanza. (#305, @voodoos)

1.8.1

Changed

• Dropped OMP dependency and use handwritten compat layers instead (#317, @NathanReb)

1.8.0

Added

• Allow to explicitly set the kind of blocks in labels: ocaml, cram, toplevel or include. (#237, @gpetiot)
• Include blocks do not require an empty block anymore (#286, @gpetiot)
• Support for OCaml 4.12 (#298, @kit-ty-kate)

Changed

• Improve error message of cram test exceptions due to empty lines in a block (#270, @pitag-ha)

Fixed

• Report #require directive errors (#276, @gpetiot)
• Handle no such file exception: the input file and the values of options --root and --prelude are checked (#292, @gpetiot)
• Keep locations from parsing instead of recomputing the lines, providing better error messages (#241, @gpetiot)
• Use create_process instead of execvp to call mdx-test from mdx. This fixes running mdx from dune on Windows (#299, @emillon)

1.7.0

Added

• HTML comments can carry block labels (#234, @gpetiot) The syntax is: <!-- $MDX labels -->, where labels is a list of valid labels separated by a comma. This line has to immediately precede the block it is attached to. The legacy syntax is preserved and will be deprecated in a later release.
• Add support for toplevel blocks in .mli files' doc comments (#206, @jsomers)
• Add support for OCaml 4.11 (#261, @kit-ty-kate)

Changed

• Apply unnamed preludes to all environments (#271, @gpetiot) New behavior:

  • env_and_file "a:f" associates f to the environment named a
  • env_and_file " :f" associates f to the default environment
  • env_and_file "f" associates f to all environments.
• Errors in non toplevel OCaml blocks are now printed to a seperate mdx-error code block following the ocaml block instead of crashing the mdx process. Those mdx-error blocks are recognized and checked by mdx and can be intentionally used to show case specific compile errors. (#238, @gpetiot)
• Improve error reporting for invalid (* $MDX part-... *) delimiters (#250, @gpetiot)

Deprecated

• The command 'mdx rule' is deprecated and will be removed in 2.0.0 (#251, @gpetiot)

Fixed

• Fix toplevel parsing when phrases contain tabs (#240, @gpetiot)
• Avoid adding newlines to empty blocks (#253, @gpetiot)
• Preserve the indentation of included files (#259, @gpetiot)
• Preserve the header in shell blocks (#249, @craigfe)
• Support underscores in environment variables in set- and unset- labels (#257, @shonfeder)
• Fix mdx on Windows which was looking for the ocaml-mdx-test binary at the wrong place (#263, @hcarty)
• Properly report mdx parsing errors instead of crashing with an uncaught exception (#267, @gpetiot)

1.6.0

Added

• Add a --duniverse-mode to ocaml-mdx rule so that the generated rules work within a duniverse
• Allow to import arbitrary files (not only .ml/.mli ones) into code blocks using the file label. (#203, #207, @voodoos)
• Allow to set the --non-deterministic option through the MDX_RUN_NON_DETERMINISTIC env variables (#208, @NathanReb)
• Add support for OCaml 4.10 (#204, @kit-ty-kate)
• Infer syntax kind when --syntax is not set, and add 'markdown' as an alias to 'normal' (#222, @gpetiot)

• Add new delimiters syntax using comments for partial OCaml files include (#212, @voodoos).

Changed

• Do not unset INSIDE_DUNE when executing shell commands by default (#224, @NathanReb)

Fixed

• Fix a bug that could cause ocaml-mdx test to crash on some include in toplevel code blocks (#202, @trefis)

Removed

• Remove the direction option, only synchronize from .ml to .md files (#214, @gpetiot)

1.5.0 (2019-11-29)

Added

• Add a --output/-o option to the test subcommand to allow specifying a different output file to write the corrected to, or to write it to the standard output (#194, @NathanReb)
• Migrate to OCaml 4.08 AST to add support for let* bindings (#190, @gpetiot)
• Add --syntax option to rule subcommand to allow generating rules for cram tests (#177, @craigfe)

• Remove trailing whitespaces at the end of toplevel or bash evaluation lines (#166, @clecat)
