Release v4.19-414

CHANGES:

Mon Jun 23 10:10:42 CEST 2024

  + merlin library
    - Expose utilities to manipulate typed-holes in `Merlin_analysis.Typed_hole`
      (ocaml#1888)
    - `inlay-hints` fix inlay hints on function parameters (ocaml#1923)
    - Handle class type in outline (ocaml#1932)
    - Handle locally defined value in outline (ocaml#1936)
  + vim plugin
    - Added support for search-by-type (ocaml#1846)
      This is exposed through the existing `:MerlinSearch` command, that
      switches between search-by-type and polarity search depending on the
      first character of the query.

Release v5.4.1-503

CHANGES:

Mon Jan 13 10:55:42 CET 2025

  + ocaml-index
    - Bump magic number after index file format change (ocaml#1886)

Release v5.4-503

CHANGES:

Fri Jan 10 17:55:42 CET 2025

  + merlin binary
    - Support for OCaml 5.3
    - Use new 5.3 features to improve locate behavior in some cases. Merlin no
      longer confuses uids from interfaces and implementations. (ocaml#1857)
    - Perform less merges in the indexer (ocaml#1881)
    - Add initial support for project-wide renaming: occurrences can now return
      all usages of all related definitions. (ocaml#1877)
  + vim plugin
    - Added support for search-by-type (ocaml#1846)
      This is exposed through the existing `:MerlinSearch` command, that
      switches between search-by-type and polarity search depending on the
      first character of the query.

Release v5.3-502

CHANGES:

Tue Nov 26 17:30:42 CET 2024

  + merlin binary
    - Respect the `EXCLUDE_QUERY_DIR` configuration directive when looking for cmt
      files (ocaml#1854)
    - Fix occurrences bug in which relative paths in index files are resolved against the
      PWD rather than the SOURCE_ROOT (ocaml#1855)
    - Fix exception in polarity search (ocaml#1858 fixes ocaml#1113)
    - Fix jump to `fun` targets not working (ocaml#1863, fixes ocaml#1862)
    - Fix type-enclosing results instability. This reverts some overly
      aggressive deduplication that should be done on the client side. (ocaml#1864)
    - Fix occurrences not working when the definition comes from a hidden source
      file (ocaml#1865)

Release v4.18-414

Release v5.2.1-502

CHANGES:

Fri Sep 27 12:02:42 CEST 2024

  + merlin binary
    - A new `WRAPPING_PREFIX` configuration directive that can be used to tell Merlin
      what to append to the current unit name in the presence of wrapping (ocaml#1788)
    - Add `-unboxed-types` and `-no-unboxed-types` as ocaml ignored flags (ocaml#1795, fixes ocaml#1794)
    - destruct: Refinement in the presence of optional arguments (ocaml#1800 ocaml#1807, fixes ocaml#1770)
    - Implement new expand-node command for expanding PPX annotations (ocaml#1745)
    - Implement new inlay-hints command for adding hints on a sourcetree (ocaml#1812)
    - Implement new search-by-type command for searching values by types (ocaml#1828)
    - Canonicalize paths in occurrences. This helps deduplicate the results and
      show more user-friendly paths. (ocaml#1840)
    - Fix dot-merlin-reader ignoring `SOURCE_ROOT` and `STDLIB` directives
      (ocaml#1839, ocaml#1803)
  + editor modes
    - vim: fix python-3.12 syntax warnings in merlin.py (ocaml#1798)
    - vim: Dead code / doc removal for previously deleted MerlinPhrase command (ocaml#1804)
    - emacs: Improve the way that result of polarity search is displayed (ocaml#1814)
    - emacs: Add `merlin-search-by-type`, `merlin-search-by-polarity` and change the
	  behaviour of `merlin-search` to switch between `by-type` or `by-polarity`
	  depending on the query (ocaml#1828)
