typit-learn

This plugin offers a mode that records how you fix a typo. The next time you make that same typo, it will remember it and fix it automatically.

What problem does typit-learn solve?

When looking for ways to make text editing more efficient, you often hear about using abbreviations to automatically correct typos. Briam Moolenaar himself, the creator of vim, has both talked and written about that specific piece of advice.

But I could never make the habit stick. While "using abbreviations" seems reasonably simple, lazy people like myself feel discouraged just contemplating all the steps required to make this work consistently:

• Obviously, I first have to correct the typo.
• Then, I create an abbreviation, add it to a file and source the file in my vimrc.
• Hey, maybe I made the typo elsewhere but missed it earlier. Better search for that typo and replace it with its fix.
• Repeat the first three steps each time I make a typo.
• Now I have to maintain a whole file of abbreviations. Maybe some of them introduce some conflicts over time, or perhaps I accidentally overwrite old abbreviations I forgot about.
• Some months later, I find myself with a whole lot of abbreviations and have to deal with a lot of unwanted expansions that I want to undo, but I can't easily do that in vim.

So, yeah, it's doable. It's just not easy enough for me.

What I want is to fix a typo once, and forget about it forever. I want vim to learn from my typos automagically. If I could do some cool scikit-learn, machine learning stuff happen, I would. But that's way too much work, so I made typit-learn instead.

Features

• Typo recording mode: type <leader>q, fix as many typos as you want, type <leader>q again. Done! All your typos (and their respective fixes) have been recorded.
• Undo abbreviation expansion: you can use the regular vim undo commands to undo a fix if you want to. Can be disabled with g:tplearn_undo.
• Maintain a list of typos: typit-learn will let you know if you risk erasing an existing abbreviation, or using a fix that's already known as a typo.
• Spellchecking: typit-learn can check whether the typos you're trying to fix are actually valid words in your dictionary. Especially useful if a word is a typo in one language but is correct in another that you're less familiar with. Off by default, you can turn it on with let g:tplearn_spellcheck = 1.
• Fix all typos at once: after you record a new typo, typit-learn will automatically fix any other occurrence of that typo in the current buffer.

Testing

You can run pytest at the root of the directory. Some tests need an open instance of nvim to pass (they'll be skipped otherwise), you can start it with:

./test/manual_test.sh

You can also install the pre commit hook by running the following command at the root of the directory:

ln -s ../../test/pre_commit.sh .git/hooks/pre-commit
