Prelude

Emacs is slowly, but firmly moving in the right direction with Emacs 24. A lot of new important features are coming, the release date is nearing, but there is something worrisome on the otherwise bright Emacs horizon. It’s a remnant from the Dark Emacs Days and it’s called EmacsWiki.

Shortly put - EmacsWiki is a blight.

A Little Bit of Background

Here’s the longer story. EmacsWiki was created by Alex Schroeder (aka kensanata) way back (in 2001) with the goal to become the home of all the Emacs information one would ever need (both about Emacs in general and its extensions). I have to admit that this was a noble goal and I know that Alex had all the right intentions, but unfortunately right intentions rarely are enough for things to always move in the right direction.

The software behind the wiki is called OddMuse and it’s authored by Alex himself. It’s pretty basic Perl script and doesn’t feature db support. Its motto is No MySQL; no PostgreSQL; no worries. - wish it were true…

The Problems

The EmacsWiki has several epic problems. Here we go:

Odd Choice for a Wiki

Even if in the beginning OddMuse might have been a good choice (Alex authored it and MediaWiki didn’t exist back then), it hasn’t been a good choice for quite a while. There are much better solutions in terms of markup support (Markdown anyone?), usability and performance. Some of the features of the wiki are simply abhorring - like the lack of user access control; anyone can enter any user name and edit the wiki… Yep, this is not a joke…

Moderators, Where Art Though?

I’ve never seen so much junk in a wiki in my entire life (and I’ve seen the wikis of 15-year enterprise systems). When I was an Emacs beginner I often consulted the wiki for advice - even then I noticed that there were some suspicious practices being suggested there. Now I can say with certainly that much of the content there is total bullshit - it’s mostly written by people with very little knowledge of Emacs (not to mention good Emacs practices). The articles are littered with crappy advice confusing beginners, have little structure and are filled with ridiculous questions (questions in an wiki???). All of this would have been avoided had the EmacsWiki had a team of moderators to keep shitty contributions at bay. Alas, such a team does not exist (or does a very crappy job of it).

Software Distribution Medium

As crazy as it seems a lot of people are using the wiki as a software distribution mechanism. Instead of hosting their projects in version control (say GitHub) they develop stuff locally, upload them to the wiki and say that this is the canonical way to obtain their software. Needless to say - this is a horrible, horrible practice. I’ve often encountered on the wiki source files authored by someone, then edited by 10 different guys, that have a tendency to add their names to the copyrights sections instead of thinking how their poor users will understand what exactly was changed in these files. Sometimes the authors themselves are to blame (for being fucking lazy), but often someone just copies a snapshot of a project from version control and uploads it to the wiki, creating problems of epic proportions for the maintainers, who start receiving bugs about stuff they never developed in the first place.

For the love of God - take your project(s) to GitHub and develop them there with pleasure, under the scrutiny of an active and passionate developer community. Wikis should be used for documentation only!

Tools like audo-install (an extension that supports installing software from EmacsWiki) should never have existed. el-get should not have added support for the installation of stuff from the wiki. As long as such practices are tolerated they will not stop.

Need I remind you that we’re now living in the era of package.el and distributed version control (Git, Mercurial, Bazaar)? Act accordingly!

Jack of All Trades

Documenting each and every Emacs project is an impossible task. And it should not be centralized. Each project should be responsible for producing its own up-to-date easy-to-follow crystal-clear documentation. By putting everything in one place you’re just making sure you’ll end up with a pile of out-of-date confusing unstructured ramblings (the EmacsWiki proves my point).

An EmacsWiki shouldn’t list tips on the use of external projects - such tips should be in the project’s wiki. An EmacsWiki should document the core Emacs experience and customizations only.

The Solution

Kill the EmacsWiki! (may it be reborn from its ashes)

Action Plan for The Maintainers

Drop the current format of the wiki - use something standard like MediaWiki instead of OddMuse. Drop all the articles about Emacs extensions. Drop all the extensions hosted there. Assemble a team of moderators. Accept only articles about general Emacs usage and Emacs Lisp programming.

Action Plan for Emacs Extensions Authors

If you’ve got a normal project hosted on GitHub (or a similar service)

delete everything about your project on the wiki and don’t respond to any bug requests regarding modified copies of your sources distributed via EmacsWiki.

If you’ve got a project hosted on the EmacsWiki - there is still a chance for you to redeem yourself. Migrate your project(s) to GitHub (you’ll thank me later for that). Use their version control, their issue tracker, their wiki system. Start distributing your project via Marmalade or MELPA ( package.el repos). Your life will become much nicer and the visibility of your project and the possibility to attract new developers will be significantly boosted. GitHub is a project hosting solution, the EmacsWiki is not.

The Regular Users

Boycott the wiki (unless the maintainers take actions)! Submit documentation only to the official project pages. Ignore projects hosted on the EmacsWiki. (or migrate them to GitHub if they seem orphaned and try to rekindle them)

Epilogue

Do we need an EmacsWiki? Certainly we do! But we need a real EmacsWiki and not this abomination that is currently a detriment to new Emacs users, instead of help. The wiki needs restructuring, but first it needs to die. I hope you’ll see the truth in my words and take action instead of commenting how outrageous my claims are. Do something meaningful for a change - save a project from the EmacsWiki, contribute documentation to an official project’s wiki, package something on Marmalade…

Die, Die EmacsWiki! I’ll be seeing you in hell…

Update

This post stirred a huge discussion online and as a result there is now another Emacs wiki out there. The new wiki is available at http://wikemacs.org. It’s using MediaWiki (it turned out it had several nice advantages over MoinMoin).
