DESCRIPTION
Aquamacs Emacs is a Mac-like distribution of the powerful Emacs text editor. It looks and behaves like a Mac program - even though it's still GNU Emacs with all the extensibility that millions have come to appreciate.
Emacs is a text editor of legendary power and configurability, but it also has an enormously complex interface. Aquamacs tames the Emacs tiger: you get Apple shortcuts (in addition to the Emacs ones), nice fonts, one file per window (if wanted), international input methods, Apple Help manuals and more. Aquamacs comes with a range of modes for various markup and programming languages: HTML, C/C++, Java, Python, Perl, AppleScript, Tcl, XML, R (S)... These modes have extra functions for the languages, including excellent syntax highlighting. You can even use Aquamacs to read news and e-mail, just like any Emacs.
WHAT'S NEW
Version 1.8a:
- Tabs are now directly accessible using keys A-M-1,2,3...9,0 (normally: Command-Option-1,2,3...9,0). The number of each tabs is marked. For configuration, see the new customization variable `tabbar-show-key-bindings' and the function `tabbar-define-access-keys'. For instance, use (tabbar-define-access-keys '(alt)) in your Preferences.el file to use Command-1,2,3.. bindings.
- Aquamacs now asks for confirmation when printing is requested via A-p. This helps avoid long waits for rendering with large buffers when A-p is pressed by mistake.
- On systems with faulty LaTeX installations, Aquamacs will now do a better job at choosing the right TeXLive (or legacy teTeX) binaries.
- When scrolling back and forth page-wise, the point will now end up in its previous position.
- Command-, can now be re-bound via the normal Aquamacs key maps (`osx-key-mode-map') . (Note that even if rebound, the application menu will still show the A-q and A-, key bindings for Quit and Preferences, respectively). A-h remains unmappable for now. Reported by Chris Bernard.
The mark is now deactivated when point is restored while switching tabs (in transient-mark-mode, which is on by default).
- Command-C (clipboard-kill-ring-save) will take care not to create duplicate entries in the kill ring. Reported by Konrad Podczeck.
- Fixed a rare failure of dired to view directories. Reported by Uwe Pieczynski.
- Fixed a startup failure when environment variables with values where used that could no be encoded with the coding system assigned to the system's ``input source'' language. (`locale-coding-system' is now set according to the locale in the default login shell.) Reported by André Berg.
- Fixed an error when deleting the whole buffer contents while smart-spacing-mode was on. Patch by Jon Shea.
- Fixed a potential security hole in smtpmail. Code by Simon Josefsson.
- `LaTex-mode-hook' can now be customized and saved through the customization interface. Reported by Bruno Cadonna.
- ESS (R-mode) will now retain an active mark (and region) after evaluating code, e.g. with C-c C-r.
- In the keyboard emulation modes that allow the mac-native use of Option on various keyboard layouts, while retaining Option as Meta key for Emacs, ESC key sequences always act as Meta sequences. For instance, with the German layout, ESC-l acts as `downcase-word' (the original M-l binding), while Option-l inserts the @ sign.
- Adopting fonts as default fonts for frames: keep frames inside screen. Reported by Stefan Vollmar.
- The Aquamacs application bundle has shrunk by about 17 MB thanks to compression.
REQUIREMENTS
Mac OS X 10.4 or later.

PENG BAI Good app! I use it for Latex and Python. However, poor at Python, so plug-in needed. I hope Python can be enhanced in this app:) | |

DAVIDSWELT which plug-in do you use? (Version 1.8a) | |

PENG BAI python-mode (Version 1.8a) | |

DAVIDSWELT Actually, Aquamacs already comes with python-mode and all you need to do is We will enable this variant by default for python in future 2.0 series releases. Thanks for your input. (Version 1.8a) | |

DAVIDSWELT Want to check out our latest work? Download a nightly build of the new 2.0 branch, which is based on Cocoa and Emacs 23. It's far from perfect yet, but already quite usable: http://aquamacs.org/nightlies.shtml (Version 1.8a) | |

DAVIDSWELT If you're on a PPC Mac and you downloaded 1.6preview4 on Monday Dec 29, you may encounter a problem with the Finder refusing to run Aquamacs ("not for this architecture"). We've fixed this - just download again. If you're not on PPC, there is no need to download it again. (Version 1.6pre4) | |

PIXIEMOTION Aquamacs has become a really mature Emacs for OS X; the balance between Mac usability and Emacs power is near-perfect. If you've never used any Emacs before, this is the best way to get to know it. If you have used Emacs before, this is the best Mac distribution. (Version 1.5rc1) | |

NGOLES This is a great piece of software, the Apple Scientific and some of the developer communities will make great use of this software. | |

JOHN NOWAK First off: No, it is not a beautiful Cocoa editor. It isn't supposed to be. It is supposed to be a Mac version of emacs that doesn't require X11 and integrates a bit better with the system -- And it does that. Very solid documentation, good stability, lots of included packages, good concept, and a wonderful implementation. (Version 0.9.9d) | |

IFX It is very disappointing to hear negative comments about this gem of software, just because of a couple of icons that are not in the taste of some readers. Apparently there is a deep ignorance in part of the current Mac community about Free Software. Apparently there is also deep ignorance about the outstanding contributions of Richard Stallman and his beautiful creature, Emacs. Maybe this is due to the massive Apple campain to have win users to switch, which will eventually poison the community. But what I would like is that people think and get documented before commenting. Emacs and VI have been the only two free, powerful, programmable and customizable text editors for ages. Platform independent. If someone does not understand programming languages and lisp, then she better avoid commenting about Emacs. If someone writes documents in M$ Word and similar crap editors, because he does not know how to use LaTeX, then he better stay silent about Emacs. I've been using Emacs for 15 years over several Unix platforms and it never (yes, never) let me down with a lost file because of a crash. Aquamacs, in particular, is the best possible incarnation of Emacs in MacOs. If someone needs some silly aqua-fresh look then she better use TextEdit or buy herself some expensive license. He probably cannot even tell the difference between TextEdit and a programmable editor. (Version 0.9.9c) | |

MDMUNOZ Wow. Let me say this: contrary to what you imply, there are other (read: not emacs) open-source editors for the mac that integrate completely into the os, follow human interface guidelines, and aren't bloated with 30 megs of crap. Emacs can do lots of neat things, but it's clunky and unusable for a lot of people. Alluding to some sort of windows-switcher ignorance or love of eye-candy won't save you from the reality that emacs is bloated and anachronistic. Most people want to actually edit text in a way that is intuitive, simple, and plays nice with their operating system. if you want to spend all day writing lisp hacks so you can attempt to finally create that Photoshop emacs extension that has so long kept it from being its own operating system, more power to you. But that's no reason to whine about the "ignorace" of the Mac community. (Version 0.9.9d) | |

NGOLES I use TextMate for my editing, please point me to other "Free Open Source full Aqua appearance" OS X editors ( for programming of course , or laTex ). This is a great piece of software, I say so even if I haven't used emacs at all ever ( I always used VI ). (Version 1.4) | |

JJL Aquamacs is now a lovely size 134.4 MB in its .app directory, somewhat voluptuous compared to twiggy TextMate's 29.9 MB. However, they both zip along gracefully on two cores clocking 2.3 GHz. A twenty-year marriage to emacs can't be without some nostalgia and a quiet reverence for the many occasions emacs has saved my life, my ambitions, or, at minimum, my sanity, on no fewer than a dozen distinct operating environments. Aquamacs 1.5, in D. Reitter's caring and thoughtful hands, shines in its elegant, talented demonstrations of refined, tested, experienced design. In OS 10.5.5, I do prefer TextMate to any other among its peers. It is a young code-base, but plainly brilliant and prodigious. It has the great advantage of having lived it's most formative years contemporaneous with OS X, and this shows in its resilience and creativity with the networked, many-tiered problems that have come to fore in modern times. Frankly, I adore them both. (Version 1.5) | |
