This plugin enables folding by section headings in markdown documents.
This plugin adds the ability to fold the following markdown elements:
- Headings and everything under them
- Fenced code blocks
By default this plugin will use "Stacked" folding which looks like this when everything is folded.
1 ## Topmost heading [3 lines]--------------------------- 5 ### Second level heading [3 lines]--------------------------- 9 #### Third level heading [3 lines]--------------------------- 13 #### Another third level heading [2 lines]---------------------------
You can use "Nested" folding, where folding the "Topmost heading" will also nest all the deeper sections under it.
1 ## Topmost heading [14 lines]--------------------------
To toggle between the two folding styles use
If you'd like to have it default to "Nested" folding add this to your
autocmd FileType markdown set foldexpr=NestedMarkdownFolds()
markdown-folding using a Vim package manager ( vim-plug, pathogen, Vundle, or Vim 8's native plugin system ). You will need to add the following lines to your
~/.vimrc file or
~/.config/nvim/init.vim for NeoVim:
set nocompatible if has("autocmd") filetype plugin indent on endif
markdown-folding plugin provides nothing more than a
foldexpr for markdown files. If you want syntax highlighting and other niceties, then go and get tpope's vim-markdown plugin.
First, Vim must recognize the file you are in as a Markdown file.
filetype=markdown. If it doesn't you may want to tweak your
filetype.vim to make sure it knows to associate your current file extension
with Markdown. In the short term you can
There are a variety of ways Vim can be instructed to "fold" things. When you add
a plugin to support a new language / format the plugin will tell Vim "Hey here's
the method to use for figuring out the start and end of a fold with this language".
This plugin uses a
:set foldmethod? should return
foldmethod=expr. If you see something else then you've likely got some other
Vim configuration overriding the setting in the plugin. If, after running
:set foldmethod=expr, things still aren't working, then something is most likely
amiss in your
~/.config/nvim/init.vim if you use NeoVim).
PRs are always a welcome thing, but it should be noted that the current intent is to keep this plugin pretty focused on folding Markdown.
All new PRs should include tests. If you're fixing a bug please add a test to make sure it never comes back. If you're adding a new feature please add tests to make sure we never break it with future changes.
The tests are currently all contained in
The test setup requires Ruby. For those unfamiliar with Ruby development you'll want to cd into the
vim-markdown-folding directory and run the following commands in the terminal.
Install bundler if you don't have it already.
gem install bundler
Tell bundler to install the required dependencies
Tell bundler to run the tests
bundle exec rake test
The end of the output should look something like this
t/folding.vim .. ok All tests successful. Files=1, Tests=41, 1 wallclock secs ( 0.03 usr 0.01 sys + 0.57 cusr 0.12 csys = 0.73 CPU) Result: PASS
