Eólas

Eólas is Irish for knowledge or information, especially knowledge gained by experience or practice

This repository is my technical knowledge management system or "second-brain". It comprises notes from my autodidactic study of software engineering and computer science.

Implementation

It is a Zettelkasten work in progress. I've recently converted the topic-based subdirectories into a single flat directory structure organised by tags. I'm in the process of partitioning longer notes into smaller informational units.

I use the zk CLI package to help with indexing and task automation alongside its zk-nvim Neovim wrapper. I occassionally utilise Obsidian alongside Neovim for when I want to view my notes as a knowledge graph or read them alongside their rich content (images, videos etc).

Commands

Commands are local to my Linux machine, specified in my dotfiles. They are how I generate new entries and manage the knowledge base.

Alias	Command	Output
z	cd $HOME/repos/eolas	Access Zettelkasten
zn	zk new --title ...	Create new entry from template
<leader> zk	:ZkNotes	Access Zettelkasten from anywhere within nvim
<leader> zi	:ZkIndex	Index Zettelkasten within nvim
<leader> zt	:ZkTags	View tags via Telescope within nvim
<leader> ztt	:ObsidianTags	View tags in a Vim buffer via within nvim using obsidian-nvim
<leader> zl	:ZkLinks	View links in current entry via Telescope within nvim, using obsidian-nvim
<leader> zb	:ZkBacklinks	View backlinks to current entry via Telescope within nvim, using obsidian-nvim

Frontmatter

When I run the zn command this generates a new Zettelkasten entry with the following frontmatter template:

---

title: test

Scripts

The scripts directory contains several Bash and Python scripts I use for general housekeeping, such as formatting image URLs, removing unused assets, and autosaving.

Autosave

I use a bash script to create autosave functionality via Git. This script runs every 15 minutes via a systemd time timer. It tidies up the directory (removes unused images, ensures all file names use underscores rather than spaces and hyphens etc) and commits and pushes to GitHub.
