dotfiles

Linux config files and scripts

The main branch is desktop

I'm using a slightly modified version of the method described by StreakyCobra and others in this Hacker News thread.

Installation

curl -sL https://raw.githubusercontent.com/etacarinaea/dotfiles/desktop/dotfiles-install.sh | bash

..or if you want to do it manually you can also enter the following commands in a shell:

git clone --mirror git@github.com:etacarinaea/dotfiles.git $HOME/.dotfiles
git --git-dir=$HOME/.dotfiles/ --work-tree=$HOME config \
  --local status.showUntrackedFiles no
alias config='/usr/bin/git --git-dir=$HOME/dotfiles/ --work-tree=$HOME'

General

Anki

Uses MathJax for LaTeX and Marked for markdown support.

I adapted my configuration from Niklas Korz' version here, which is based on this reddit post.

Additionally, I'm using vim to write cards, because it's a lot easier and more efficient to use than Anki's integrated text editor.

• .anki/ contains "config" files (front/back templates and styles) for Anki cards
• .vim/ftdetect/ankicard.vim adds a new filetype to vim for anki cards
• .vim/snips/ankicard.snippets uses the aforementioned filetype to define snippets for anki, extending the already existing tex snippets

.Xmodmap

Rebinds caps lock to Super_L

.config/i3/rename-workspace

Renames the current i3 workspace while preserving the numbering. Entering nothing removes the name again leaving only the number.

Example screenshot:

.config/i3status/spotifylog.sh

Gets called by dunst when Spotify sends a new notification (see .config/dunst/dunstrc). Writes the current title and artist from the notification into /tmp/spotifylog which then gets read by i3status (see .config/i3status/config).

.Xmodmap

Disables the function keys so etc/acpi can handle them instead.

etc/acpi

Handles function keys. Keys implemented:

• mute
• volume down
• volume up
• brightness down
• brightness up

Volume is only implemented for pulseaudio.

All keys also send a notification using libnotify.

Fn+Esc (FnLk) and Fn+Space (keyboard backlight) worked out of the box for me.

etc/systemd/system/wakelock.service

systemd service for locking the screen with i3lock

It also uses ImageMagick to capture the screen and then display a blurred version with some text overlaid as the lock screen's background.

The normal -blur function is pretty slow for high sigma (and -gaussian-blur is even slower), so depending on the system it could take a while for convert to run, which delays locking.

Scaling the image by some factor A < 1 and then scaling it back up by A's multiplicative inverse with a Gaussian filter with some sigma, gives more or less the same blur as applying a Gaussian blur with that sigma times the multiplicative inverse of A without scaling, and is a lot faster.

So for example if you'd usually need a sigma of 40, and you scale the image by a factor of 0.1, you end up only having to use a sigma of 4 to get more or less the same visual effect.

Obviously if the scaling factor is too small you'll end up loosing too much information and the end result will just look like a gradient or a solid colour.
