CLI tool for managing a digital Zettelkasten
# settle

`settle` is a CLI tool that helps you manage your digital Zettelkasten.

First, a little bit of history. I learned about the Zettelkasten method back in
the summer of 2021. I looked at a few programs for it, and I settled on Obsidian
MD. But I didn't like the experience: I was an avid Vim user, and the vim
compatibility mode wasn't usable in the least. I had alreay written quite a few
notes, and I didn't want to change them to make the links and tags work with
other programs.

So there I was, in early August, with the idea of writing a CLI program that I
could easily use with Vim (or any editor, for that matter), and at the same time
use Obsidian-style links and tags. In the meantime, I've read Sonke Ahrens's
*How to take smart notes* and have been adding features to settle. Almost a year
later, and I can confidently say that it's pretty good.

There are several core principles in the design:

- ***plain and simple***: notes are stored locally and written in markdown

- ***manage notes, not editors***: it's the same Zettelkasten everywhere you go.
    The editor you use doesn't matter. Integration is done through (editor)
    plugins (e.g. settle.vim).

- ***database mirrors notes***: metadata is determined by what's on the file
    system, not by commands. The only way to add or remove links and tags is to
    write, then tell `settle` to update the note(s).

- ***you can use projects, but take care***: instead of using tags and putting
    things in the main Zettelkasten, notes like those containing games' lore or
    chapters of a book you're writing can be put in a *project*.

    The root of your Zettelkasten is a project, your inbox is a project, etc.
    However, the separation is only formal, since links can reference notes in
    any project. It's really easy to misuse them, unfortunately: they're meant
    to be discarded after the project is done, or incorporated into the main
    Zettelkasten. Either way, they're *not* supposed to be permanent.

- ***add, change, but never remove***: notes may be created, but never destroyed
    by the program. At most, they can be renamed or moved from project to
    project.

- ***made by humans, for humans***: no YAML metadata; links and tags are
    embedded within text, allowing you to give context to connections between
    ideas

## Getting started

### Requirements

* cargo/rust toolchain
* SQLite

### Installation

There's a crate on crates.io, so you can simply run:

```
cargo install settle
```

### Usage

For the commands, options, configuration, and setting up autocompletion, read
[the manual](./doc/SETTLE_MANUAL.md)

If you prefer, there's also a groff document inside the `doc/` dirctory which
can be read with `man`. On the command line, of course.

### The note-taking system

`settle` just stores and manages a database of Zettel metadata. That's it.

There are two important things to remember when writing:

- wiki-style links are used to denote the actual links between Zettel. For
    example, a link such as `[[Neurons]]` would be considered as linking to a
    note called *precisely* 'Neurons'. These can appear anywhere in the note.
- every word with a hashtag prefix is treated as a tag. For example,
    `#psychology`. Subtags (hierarchical tags), such as
    `#biology/anatomy/humans` are supported, if you want to stay more organised.
    You can also put these everywhere.

Besides, how do you actually start writing, if there are no explicit commands to
invoke an editor? It'd have been hard trying to write code so that it works
smoothly with vim or emacs and their many quirks. Instead, editor-side code is
written to act as a settle plugin.

I wrote [settle.vim](https://github.com/xylous/settle.vim) since I'm a (neo)vim
user myself. If you write a wrapper around settle, contact me at
`xylous.e@gmail.com` and I'll make a list or something.
