Zettelkasten.nvim

To develop / debug:

start neovim with nvim --cmd "set rtp+=$(pwd)" . to automatically load the files in project dir as if they were on path

next up: [ ] fix link following:

• empty space (e.g. in link text, or link itself) disrupts link regex search
• line-end following breaks if cursor is in the MIDDLE of the link
• extract anchor from link/string (anchor.lua)
• opening zettel should use generated link table for full filename anchor search
  • probably stop hardcoding anchor regex, make an option
• implement fallback to filename

TODO: needed functionality

• note creation (new anchor)
  • create anchor
    • unique anchor creation
  • create link (md / wiki)
• note listing (anchors / titles, no anchor)
  • list anchors
  • list filenames
• link following (to existing anchor)
  • fallback to filename if anchor invalid / not found
• link creation (to existing note)
  • list existing
  • create link (md / wiki)
• link switching (point to another existing note)
• note search (title / full-text)
• jump to zettel (open existing anchor)
  • select by anchor
  • select by (fuzzy) title match
• options
• zettel anchor separator
• zettel extension
• link style (wiki/markdown)
• custom link style?
• link detection/following (under word, next on line)
• recursive dir lookup for zettel
• zettel anchor regex

TODO: nice-to-haves

• refactor parsers (md/wiki) to be tables of functions/regex in options, so e.g. valid link detection can call options.parser.isValidLink(link) or transformation options.parser.styleLink(anchor, text)
  • use unified parser model (e.g. containing turn-to-link(), parse-link()) function
  • enable custom parser supply
• completion engine (e.g. for completion-nvim, look in completion_buffers/completion-tags for reference)
• zettel caching for big directories
• backlinks (via rg for filename anchor?)
  • keep tree of notes cached?
• zettel maintenance
  • fix malformed anchors
  • add missing anchors
  • 'rename' anchor (goes against stability?)
  • recognize duplicate anchors (in directory, when listing, etc)
    • provide option to rename and automatically change backlinks
• zettel 'lens' (preview first headline + content of linked zettel through floating window etc, on keypress)

TODO: maintenance

• remove hard-coding of option vimnames in tests, now that we can dynamically change this through a single table

• anchor creation

  • must be unique
  • default: 10 digits, usually current date+time (YYMMDDHHmm)
  • but, if multiple links created within one minute (or other circumstances), this would duplicate
  • thus, duplicate-check before creating a new anchor
  • if duplicated, generate first non-duplicated link (recursive?)
  • try to move backwards through minutes not forward
    • i.e. if 2030101200 exists move to 2030101159, 2030101158, ...
    • if moving backwards, we do not take away id space from future note creation
    • if moving forwards, every zettel created within a minute would delay next zettel creation another minute
