Some basic functionality for working with zettelkasten-style note taking

This is for my own use, based on an initial workflow in Obsidian. Probably idiosyncratic and buggy, probably will change while I figure out how I want this to work. Assumes for now that all files reside in a single folder.

Functionality

Things you can do:

• :Newz or ,nn creates a new note with filename %Y%m%d%H%M.md. Inserts a wiki-style link to the file you had open when executing the command.
• :Newzl or ,nl does the same as :Newz but also inserts a wiki-style link (eg., [[202203201616]])to the new file in the old file.
• :Backlinks or ,b searches the working directory for links to the current file and shows the hits in a quickfix window.
• :Randomzettel or ,r opens a random note from current working directory
• ,y places a wiki-style link to the current file in the unnamed register (the one used for yank).
• ,h shows the first five lines of the file linked to under cursor

Passive functionality:

• Highlights for links, hashtags, LaTex math (extremely basic, just patching up the very bad standard markdown highlighting)
• Appends .md so that a link can be followed by gf (this is important!)

TODO

• Command to mash out a pandoc-pdf of current note
  • Make it play nice with a latex .bib file

Might-do

• Link suggestion when writing [[ something
• Extract visual mode selection to new note
• Find important notes by a pagerank-style sorting
  • Use to make a map of notes? Clustering?
• Goto and create a note that's linked to but does not exist

Probaby-won't-do

• Natural language search use :Ag or :Rg from fzf.vim

Already did

• Show head of linked file
• Open random note
• Fix broken syntax highlighting for latex math in markdown
