* Changes in 2.8.0 (since 2.7.0)
See also [[https://github.com/haskell/haskell-mode/compare/2_7_0...2_8_0][detailed Git history]].
- Minimal indentation support for arrow syntax
- Avoid opening a new inf-haskell window if one is already visible.
Windows on other virtual desktops or iconified frames don't count.
- Force comint-process-echoes to nil
- Autolaunch haskell-mode for files starting with #!/usr/bin/runghc
and similar
- Added minimal major mode for parsing GHC core files, courtesy of Johan Tibell.
There is a corresponding Haskell menu entry.
- Allow configuration of where-clause indentation; M-x customize-group
haskell-indentation.
* Changes since 2.6.4
- fill-paragraph (M-q) now only affects comments, and correctly
handles Haddock commentary. adaptive-fill-mode is turned off, as it
was interfering.
- Yet more unicode symbols
- Better support for unicode encoding of haskell source files
- mdo correctly indented
- Indentation fixes, fixes to the fixes, and fixes to the fixes to the
fixes
- New command: M-x haskell-check, calls (by default) hlint on the
current file. Also bound to C-c C-v.
You can also use the flymake minor mode with this.
* Changes since 2.5.1
- Parser corrections for haskell-indentation and haskell-decl-scan
- haskell-indentation: Pressing tab in the rightmost position now
moves to the leftmost, by default with a warning.
- Typo fix: One haskell-indentation variable had ended up in the
haskell-ntation customize group.
- haskell-hoogle aliased to hoogle, haskell-hayoo aliased to hayoo
- Courtesy of Alex Ott:
- Additional unicode symbols for font-lock-symbols: () == /= >= <= !! && || sqrt
- M-x haskell-hayoo search added, opens using browse-url
- Bug-fix for inferior-haskell-type
- If haskell-indentation errors out, it now fail-safes to inserting
a literal newline or deleting one character, for return and
backspace respectively.
* Changes since 2.4:
- haskell-indentation, a new minor mode for indentation.
* Changes since 2.3:
- Update license to GPLv3.
- New derived major mode for .hsc files.
- Removed the C-c C-r binding to reload a file. You can still call
inferior-haskell-reload-file (and/or bind it to your favorite key,
including C-c C-r) or you can now use C-u C-c C-l.
- C-c C-d looks up the symbol at point in the Haddock docs.
- Haddock comments are highlighted with font-lock-doc-face if it exists.
- Use `tex' rather than `latex' for haskell-literate.
- inf-haskell.el tries to find the root of the module hierarchy to determine
the root of a project (either by looking for a Cabal file or relying on
the `module' declaration line). If all works well, this will make C-c C-l
automatically switch to the root dir, so that dependencies in other
directories are automatically found. If it doesn't, complain and/or set
inferior-haskell-find-project-root to nil.
- The new command haskell-hoogle helps you query Hoogle from Emacs.
* Changes since 2.2:
- Trivial support for Cabal package description files.
- Minor bug fixes.
* Changes since 2.1:
- There are now commands to find type and info of identifiers by querying an
inferior haskell process. Available under C-c C-t, C-c C-i, and C-c M-.
- Indentation now looks back further, until a line that has no indentation.
To recover the earlier behavior of stopping at the first empty line
instead, configure haskell-indent-look-past-empty-line.
- inf-haskell can wait until a file load completes and jump directly to the
first error, like haskell-ghci and haskell-hugs used to do. See the var
inferior-haskell-wait-and-jump.
* Changes since 2.0:
- inf-haskell uses ghci if hugs is absent.
- Fix up some binding conflicts (C-c C-o in haskell-doc)
- Many (hopefully minor) changes to the indentation.
- New symbols in haskell-font-lock-symbols-alist.
* Changes since 1.45:
- keybindings C-c <char> have been replaced by C-c C-<char> so as not
to collide with minor modes.
- The following modules are now automatically activated without having to
add anything to haskell-mode-hook:
haskell-font-lock (just turn on global-font-lock-mode).
haskell-decl-scan (just bind `imenu' to some key).
- In recent Emacsen, haskell-doc hooks into eldoc-mode.
- haskell-hugs and haskell-ghci are superceded by inf-haskell.
- Indentation rules have been improved when using layout inside parens/braces.
- Symbols like -> and \ can be displayed as actual arrows and lambdas.
See haskell-font-lock-symbols.
- Tweaks to the font-lock settings. Among other things paren-matching
with things like \(x,y) should work correctly now.
- New maintainer <monnier@gnu.org>.
