Vimliner: The Smallest, Fastest Outliner for VIM
I was quite fond of the WorkFlowy outliner until the sync failed and broke my offline access. It was just lucky that I'd made an export of my data not too long before it failed.
But really, I didn't need sync that much. I just needed a fast outliner. And what could faster than Vim? With a bit of investigation into Vim's code folding capabilities, I came up with a single-file script to turn Vim into a fast and simple outliner. It is fully functional, and is only 21 lines of code.
To install Vimliner, just copy vimliner.vim to your $HOME/.vim/ftdetect directory and use a .out extension for your outliner files. You can also use :set filetype=vimliner if you prefer not to use the .out extension.
Here is what it looks like. You just use <TAB> to open and close the folds, and navigate through your outline.
Here is the full code of vimliner.vim for the curious.
" " Vimliner is the smallest outliner for vim. It uses vim's existing code " folding capabilities with some simple configuration. The result is a fast, " powerful outliner using your favourite text editor. " " Install Vimliner by saving this file to $HOME/.vim/ftdetect/vimliner.vim " on unix, or $HOME/vimfiles/ftdetect/vimliner.vim on Windows. " " Save your outliner files with a .out extension for Vimliner to be " autodetected. Otherwise, use :set filetype=vimliner from within vim. " " The outliner uses an indentation level of 2 white spaces to create " new levels. You can use vim's default code folding shortcuts to move " throughout your outline, or just use <TAB> to open and close levels. " " The most frequent shortcut keys you will use are: " " <TAB> open or close the current fold " zx close all other folds " " Use :help fold-commands in vim for additional shorcuts. " " The fold function consumes blank lines. If you need to separate one " fold from another, use a string of space characters that match the " current indent level.
