See also 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.
- 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.
- 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.
- haskell-indentation, a new minor mode for indentation.
- 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.
- Trivial support for Cabal package description files.
- Minor bug fixes.
- 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.
- 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.
- 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>.
