Lately there has been some interest in writing with only the ten hundred most used English words. Even the news has talked about one thing that makes your computer take away words that aren't in the ten hundred most used. (Mostly the news talked about that thing because the person who wrote it did so in part to make a point about someone called Donald Trump, not because the thing was interesting in its own right. But that's okay, because the people who write the news need something to do all day just like everyone else.) Someone on Hacker News asked if there was a thing like that for Emacs. There is, sort of, but it's old and not easy to find, and it doesn't work very well. So I thought I'd write a new one that everyone can find and use. This is that thing. It knows the ten hundred most used words, and when you type a word, it checks to see if your word is one of them. If not, the computer takes away the word you typed, and suggests some words like the one it took away but which are okay to use. (This last part can be a little slow, and it isn't always very helpful, so you can turn it off if you want.) Words that start with a big letter, like names, don't get taken away, even if they would be normally. This thing doesn't know very much. If you aren't typing normally, it probably will let you get away with using words you aren't supposed to use. That's not nice, though, so don't do that. ; Contributing: If you think of a way this thing can do a better job of taking away words that aren't okay to use, let me know, or (even better) add it to the thing and then let me know. Here's where this thing lives: https://github.com/aaron-em/ten-hundred-mode.el I hope you like it!
