GNU Aspell

GNU Aspell is a Free and Open Source spell checker designed to eventually replace Ispell. It can either be used as a library or as an independent spell checker. Its main feature is that it does a superior job of suggesting possible replacements for a misspelled word than just about any other spell checker out there for the English language. Unlike Ispell, Aspell can also easily check documents in UTF-8 without having to use a special dictionary. Aspell will also do its best to respect the current locale setting. Other advantages over Ispell include support for using multiple dictionaries at once and intelligently handling personal dictionaries when more than one Aspell process is open at once.

Try it out for your self using the Aspell Spell Helper or see some Test Results Comparing Aspell with other spell checkers.

In recent years the development of Aspell has stagnated, but I have never really lost interest in Aspell. The problem was that I just did not know how to move forward in light of Hunspell slowly taking the role that I meant for Aspell to take. However, after giving it careful thought I believe Aspell future depends on making Enchant the system spell checker. This will involve some effort on the part of others to make it happen.

Getting

The latest version of GNU Aspell is 0.60.7. You can find it at ftp.gnu.org:/gnu/aspell or at a GNU mirror site. You will also need to download at least one dictionary which can be found at the same location.

If you are looking for Aspell 0.33.7, Pspell, or dictionaries for Aspell 0.33.7 go here.

A patch for ispell.el for improved Aspell support also available. This patch will notify aspell of the replacements one makes so it can improve the suggestion list in the future. A more involved patch can be found here This one also adds UTF-8 support but will only apply cleanly to Ispell.el 3.7 beta.

Support

Unofficial support for GNU Aspell can be found at the aspell-user mailing list. You do not need to be subscribed in order to post, however if you don't subscribe your post will need to be approved. The list mailing address is aspell-user@gnu.org. Please direct all problems you have with Aspell to this list and not directly to Kevin.

Getting Involved

The easiest thing you can do help out is to try GNU Aspell out and report bugs or even better submit patches to fix problems. You can either send them to the aspell-devel mailing list or via GitHub.

If you are interested in following the latest developments be sure and subscribe to the aspell-announce mailing list.

If you are a fairly regular user of Aspell consider subscribing to the aspell-user mailing list to help other users out with their problems.

If you are interested in helping with the development of Aspell or have an idea you would like to discuss post it to the aspell-devel mailing list. The aspell-devel mailing list is meant for people interested in the development of the actual Aspell utility/library. If you have a question about how to use the Aspell library please post to the aspell-user mailing list.

To Do

Lots of jobs remain to be done. Unfortunately, I do not have the time to do all so if you are interested in helping me with one of these tasks please email me at kevina@gnu.org. Good C++ skills are needed for most of these tasks involving coding.

Things that need to be done

These items need to be done before I consider Aspell finished. If you are interested in helping me with one of these tasks please email me. Good C++ skills are needed for most of these tasks involving coding.

Things I would like to get done

I would like to get these done. However, I may still consider Aspell finished with out. They will probably eventually get implemented. However, I could still use help with them.
