I've recently decided to attempt to keep all of my notes and everything
I've learned in a [Zettelkasten.](https://zettelkasten.de/) After
reading [Daryl Sun's blog
post,](https://write.privacytools.io/darylsun/100-days-to-offload-day-4)
I started looking more into the method and found it *incredibly*
intriguing. I've tried the "Evernote way" of throwing everything I come
across in a single place but it inevitable gets lost. I don't remember
what it was called but I tried another app that actually tags your files
and organises them in a nice manner. This worked well for the most part
but the graphical client was badly optimised Electron and *very* heavy.
I've also tried keeping notes in books but I was never really able to
keep up with any of it. The thing that is especially compelling about a
Zettelkasten is that I put *everything* I learn in a single text file
but link around to as many different ideas as I can, drawing my *own*
connections for me to rediscover later on.
Because it's all in a simple text file, I'm also able to create a
keybinding in [Sway](https://github.com/swaywm/sway/) that will open it
in Vim, jump to the bottom, and have a nice markdown environment ready
for me to write in. It did take a bit of configuration and looking
around for different plugins but I'm very happy with what I have so far.
2021-01-11 17:34:38 +00:00
The first thing is telling Vim to treat all `.md` files as Markdown
2021-06-26 20:51:30 +00:00
``` vim
2021-01-11 17:34:38 +00:00
" Treat all .md files as markdown
autocmd BufNewFile,BufRead *.md set filetype=markdown
```
## Visuals
2021-06-26 20:51:30 +00:00
In a long text file with a great many lines, it can be useful to find
your cursor quickly without having to search around the screen for it.
``` vim
2021-01-11 17:34:38 +00:00
" Highlight the line the cursor is on
autocmd FileType markdown set cursorline
```
2021-06-26 20:51:30 +00:00
It can also be nice to not see a ton of \[links](https\://example.com)
and \*\*bold** or \*italic* text everywhere. Sure, my eye has gotten
used to it but still. I'd rather have my terminal actually render bold
text as bold.
``` vim
2021-01-11 17:34:38 +00:00
" Hide and format markdown elements like **bold**
autocmd FileType markdown set conceallevel=2
```
2021-06-26 20:51:30 +00:00
2021-01-11 17:34:38 +00:00
If you use the `vim-markdown` plugin mentioned further on, I recommend using its option for concealing rather than Vim's.
## Spell check
2021-06-26 20:51:30 +00:00
One of the things every good editor needs is spell check and Vim is no
exception. This line enables spell check with British English for all
markdown files.
``` vim
2021-01-11 17:34:38 +00:00
" Set spell check to British English
autocmd FileType markdown setlocal spell spelllang=en_gb
```
Here's a short crash course in Vim spelling commands:
- `[s` to search for misspelled words above the cursor
- `]s` to search for misspelled words below the cursor
- `z=` to see replacement suggestions
- `zg` to add the word to your dictionary
## Goyo
2021-06-26 20:51:30 +00:00
The very first component is something I use across *all* markdown files.
[Goyo](https://github.com/junegunn/goyo.vim) is one of the first plugins
I install on any machine I'll be writing with. It enables a
"distraction-free writing environment" and I absolutely love it. It
disables pretty much all visual elements in Vim except for what mode
you're in: visual, command, insert, etc. I have a keybinding set to
quickly open/close Goyo because there is an odd issue when I switch
workspaces to and away from Vim. With two taps of `Ctrl+g`, it's back to
normal.
``` vim
2021-01-11 17:34:38 +00:00
nnoremap <C-g> :Goyo<CR>
```
2021-06-26 20:51:30 +00:00
Another line in my Vim config automatically opens Goyo for all markdown
files:
``` vim
2021-01-11 17:34:38 +00:00
autocmd FileType markdown Goyo
```
## vim-markdown
2021-06-26 20:51:30 +00:00
That latest plugin I installed is
[vim-markdown](https://github.com/plasticboy/vim-markdown) and it is
*wonderful*. I really recommend reading about all of the options but
here's what I have set.
``` vim
2021-01-11 17:34:38 +00:00
" Configuration for vim-markdown
let g:vim_markdown_conceal = 2
let g:vim_markdown_conceal_code_blocks = 0
let g:vim_markdown_math = 1
let g:vim_markdown_toml_frontmatter = 1
let g:vim_markdown_frontmatter = 1
let g:vim_markdown_strikethrough = 1
let g:vim_markdown_autowrite = 1
let g:vim_markdown_edit_url_in = 'tab'
let g:vim_markdown_follow_anchor = 1
```
2021-06-26 20:51:30 +00:00
In addition to the rest of the awesome features, the main one I wanted
is the last: `follow_anchor`. With this, I can create internal links
within the same markdown document and jump between them with `ge`. It
also lets me open both files and URLs from within Vim and without ever
having to reach for the mouse.
2021-01-11 17:34:38 +00:00
## General Vim things
2021-06-26 20:51:30 +00:00
Other, more general Vim settings that I use globally but might also be
nice for editing markdown
``` vim
2021-01-11 17:34:38 +00:00
" Have lines wrap instead of continue off-screen
set linebreak
" Gives Vim access to a broader range of colours
set termguicolors
" Converts tabs to spaces
set expandtab
" Use two spaces instead of tabs
set tabstop=2
" The same but for indents
set shiftwidth=2
" Keep cursor in approximately the middle of the screen
set scrolloff=12
" Disable mouse support
set mouse=
```

2021-06-26 20:51:30 +00:00
In all, I'm hoping that the work I've done today for improving my
markdown workflow will help me create a more effective Zettelkasten. The
*big* thing was really being able to follow internal links around
because that's the main thing with keeping a Zettelkasten: following
your ideas to see where they lead and discovering what connections you
can make to form entirely new ideas. Mine will be stored in
[Gitea](https://git.nixnet.xyz/Amolith/zettelkasten) for now but I'm
thinking about putting it here at some point. It would be cool to have a
map of my own mind very easily accessible from anywhere.

## Edit
### Time stamps
2021-06-26 20:51:30 +00:00
``` vim
2021-01-11 17:34:38 +00:00
" Insert timestamp at the end of the line in this format: 20200527T113245
nnoremap <C-t><C-s> m'A<C-R>=strftime('%Y%m%dT%H%M%S')<CR>
```
### Portable `autocmd`s
2021-06-26 20:51:30 +00:00
Put all the `autocmd` lines in the `if` statement so they don't throw
errors when the config is added to a version of vim without `autocmd`
support
``` vim
2021-01-11 17:34:38 +00:00
" Only enable autocommands when Vim supports them
if has("autocmd")
""
" Markdown Configuration
""
" Spellcheck in British English
autocmd FileType markdown setlocal spell spelllang=en_gb
" Automatically open Goyo
autocmd FileType markdown Goyo
" Hide plaintext formatting and use color instead
autocmd FileType markdown set conceallevel=3
" Disable cursor line and column highlight
autocmd FileType markdown set nocursorline
autocmd FileType markdown set nocursorcolumn
endif
```
2021-06-26 20:51:30 +00:00
I won't keep editing this post to provide updates on my config. Instead,
I recommend looking at my ["production" version on
Gitea.](https://git.nixnet.xyz/Amolith/dotfiles/src/branch/master/dotfiles/pc/.config/nvim/init.vim)
