vim-textobj-sentence VS vim-pencil

Fork https://github.com/preservim/vim-textobj-sentence and make it treat a comma as end of sentence.

There is vim-textobj-sentence to make its sentence detection slightly more intelligent, and targets.vim which gives you some nice helpers for operating on different explicit delimiters and structures.

This plugin provides motion commands based on full sentence detection. You can switch around sentences with ( and ) and use it just as any other motion commands. Depends on vim-textobj-user plugin.

Another option is vim-pencil.

Both of the above are naturally integrated into billions of nvim plugins. I store files in a cloud folder to have access to them on my phone. There are apps that allow you to work with notes written in markdown like Obsidian. You should have a way to quickly go to your writing files. You could use telescope-project.nvim, startify shortcuts, or any other session plugin. I would also recommend setting up LSP for writing. You will be able to have diagnostics, "code actions" on wrong grammar, allowing you to add words to dictionary and suppress rules. I use ltex_extra.nvim for this. There are also a good set of plugins for writing by one author, just check them at the bottom of the pencil page.

Two years ago, I did nanowrimo in Vim with a whole suite of plugins:

- https://github.com/preservim/vim-pencil

- https://github.com/junegunn/goyo.vim.git

- https://github.com/junegunn/limelight.vim.git

- https://github.com/vimwiki/vimwiki

It was fun, and the setup is almost identical to iA Writer which I appreciate. I even had it all on my phone with Termux!

Last year I just did it in Markdown in VSCode in "zen mode" which also worked pretty well. It was definitely easier to setup than Vim and had better highlighting of bold/italics/etc.

You may like vim-pencil if you use markdown. It adds several small conveniences around word wrap options, among other things. Note also that the author of pencil includes many useful links in the README for conceiving vim as a tool for prose. My workflow is based on pandoc and bibtex. But that part's not vim- specific.

The most efficient way to do this is to install the vim-pencil plugin--when you go to edit the file, say :Pencil to activate the plugin, and it'll reformat the text on the fly while you're editing it. Basically it makes vim act less like vim and more like a word processor.

You may find vim-pencil usefull. The readme has some good links.

vim-pencil sets undo points at the end of every sentence (and other things) although you might not want to install a full plugin just for that.
