The major change Windows support is contributed by David Allsopp.

Other changes are a bunch of fixes:

• compilation on FreeBSD contributed by Malcolm Matalka

• improvement to emacs mode contributed by Olivier Andrieu, Christophe Troestler and Steve Purcell

• improvement to vim mode by Fabian Hemmer and Gregory Nisbet

• fixes to ppx invocation by Keigo Imai

• missing include preventing build on some platforms contributed by Bernhard Schommer

merlin 3.0.1

Wed Jul 26 18:25:23 CEST 2017

Bug fix release after 3.0.0 major release:

• portability fixes by David Allsop in configure script and vim mode (tough Windows support is not ready yet)

• preliminary support for findlib toolchains with FINDLIB_TOOLCHAIN .merlin directive

• make ocamlmerlin.c frontend more portable

• various fixes to the frontend

merlin 3.0.0

Mon Jul 24 11:21:58 CEST 2017

The major change is a new protocol that moves process management inside Merlin codebase, saving a lot of pain in Emacs and Vim. There are not much new user facing features.

Windows support is not yet available.

In editor configuration is now done with merlin-flags, merlin-extensions and merlin-use in Emacs and :MerlinFlags, :MerlinExtensions and :MerlinPackages in Vim. In previous versions, enabled extensions, flags and packages were retained while now only the last command is remembered.

"M-x merlin-use a", "M-x merlin-use b" should be replaced by "M-x merlin-use a,b". ":MerlinUse a", ":MerlinUse b" should be replaced by ":MerlinUse a b".

The old protocol is still supported, so existing editor modes should not be affected (tested with Atom, Visual Studio and Sublime-text).

Other main changes:

• Support for OCaml 4.05 was added

• Merlin uses a new implementation of short-path by Leo White which addresses performance problems

• Merlin now works with the upstream version of Menhir

• numerous cleanup and refactoring to decrease the amount of changes to upstream typechecker

• emacs-imenu feature was contributed by tddsg. It is similar the "outline" feature in vim for navigating in a buffer.

Thanks to the many contributors (Jochen Bartl, tddsg, Ximin Luo, Jason Staten, Leo White, Leandro Ostera, Jacob Bass, Xavier Guérin, Yotam Barnoy, Jacques Pascal Deplaix, David Allsopp, ...).

merlin 2.2

Wed May 20 09:44:55 EDT 2015

• backend:

  • completion

    • return the type of the expected argument when completing an application. This allows us to offer completion for named and optional parameters, as well as polymorphic variants

    • optionally associates ocamldoc comments to candidates

    • adds field completion inside records ( #296 )

  • locate:

    • partially rewritten, introduces a new kind of cache (so potentially noticeably bigger memory consumption)

    • better handling of functors

    • handle local modules

    • fix occasional "inconsistent assumptions"

  • error reporting:

    • handle environment errors (inconsistent assumptions, …)

    • filter duplicated messages

    • fix type error reporting: "this expression has type t = t but an expression was expected of type u = u" we now only print the equality when it adds some information

    • less noisy pattern recovery: when every pattern is recovered, consider that the matched expression is the the source of the problem, and retry typing with "'a" as the type of the matched expression.

  • add support for trunk

  • add a "document" command: takes an ident and return its documentation (if any)

  • destruct: use more precise environments ( #389 )

  • warnings:

    • check signature inclusion to prevent spurious warnings about unused declarations

    • backport 4.02-style warning management

    • add a dump command

  • nonrec: update implementation to more-or-less match the upstream one (upstream >= 4.02.2)

  • parser: improve marking heuristic in presence of ;; or toplevel directives.

  • typeof: during verbose expansion, also print the type declaration if we have a type constructor

• emacs:

  • fix bindings of every completion backend

  • bind ocamldoc comments to company (optional)

  • detect race conditions when running synchronous commands

  • cleanup "merlin-process-started-p"

  • locate error messages were silently ignored, they are now printed

  • drop text properties from commands sent to merlin (pull request #383 by milanst)

  • Tell merlin the content of the buffer when opening a new buffer. This allows merlin idle-job to preload content if nothing else is requested.

  • remove call to merlin from the lighter

• vim:

  • fix ctrlp binding for locate

  • add (dwim) completion on :TypeOf

  • while completing, candidates documentation can be displayed in the "preview" window

  • prefix every command name by "Merlin" ( #379 )

  • Tell merlin the content of the buffer when opening a new buffer. This allows merlin idle-job to preload content if nothing else is requested.

merlin 2.1.2

  • Refuse/Resist... environment variables redefinition

• vim:

  • fix charset/encoding detection (pull request #352 by rgrinberg)

  • minor fixes and simplification

• emacs:

merlin 2.1.1

Wed Jan 28 08:59:20 GMT 2015

• backend:

  • locate: merlin refused to locate things when it had no context (happens when the buffer didn't parse for example) claiming it was at the "definition point". Fixed.

  • locate: use the cmt path when no ml file was found in the source path (this might not be such a good idea, the cases when this work are the ones where the user configuration is wrong...)

  • destruct: qualify introduced constructors

  • destruct: eliminate "impossible" GADT branches

  • parser: handle '%' as an operator for 4.00 and 4.01 ( #345 )

• fake:

  • "smart" (a.k.a "do what I mean") completion: L.m will expand to List.map ; List.m... ; ListLabels.map ; ... if L doesn't exist.

  • simplify incremental parser and typer interfaces

  • locate: better handling of packed modules (supposedly)

  • more precise recovery on patterns (before the recovery was done at the expression level, so the whole match was discarded, now only the pattern is)

• emacs:

  • don't use fringe in emacs23 (broken)

  • remove obsolete aliases: merlin-occurences => merlin-occurrences merlin-to-end => merlin-error-check

  • disable merlin-mode on type buffer

  • require caml-types (needed for highlighting) (#331).

  • add support for text objects based on type enclosing

  • introduce an interactive version of :Rename

merlin 2.0

Fri Oct 31 11:04:21 CET 2014

• backend:

  • lazy processing of open directives makes merlin much faster

  • simplified buffer management

  • tweak signal handling to improve windows compatibility

  • track verbosity of query: repeated queries are considered more "verbose"

  • type expansion: expand type aliases for verbose query

  • add support for OUnit-like Benchmark extension

  • more tolerant type checker, to provide completion on ill-typed expressions

  • proper version reporting with git revision

  • refactored logging subsystem

  • one distribution for 4.00 and 4.01, introduced common interface between both, typers now live in https://github.com/def-lkb/merlin-typers

  • new implementation of the main merlin state tracking ast & types

  • better error reporting thanks to a contribution from Ronan Lehy

• documentation:

  • started a wiki (https://github.com/def-lkb/merlin/wiki)

  • successive call to C-c C-t do not climb the typed tree but improve merlin's verbosity. To move inside the tree use C-down and C-up (which implements phrase movement if there is no enclosing started).

  • customize data for merlin

  • refactoring and numerous bugfixes
