Day 450

Kitty - the terminal emulator

Added bindsym $ms+Return exec ~/.local/kitty.app/bin/kitty to ~/.config/i3/config kitty - the fast, featureful, GPU based terminal emulator — kitty 0.17.1 documentation is really awesome actually, and noticeably faster than any other terminals I’ve used.

TODO - read through the documentation linked above, esp wrt zooming and config.

<Ctrl+Shift+F2> opens the config file. In general I love everything about Kitti for now, in all the tiny little details.

Changes:

font_family      FiraCode-Bold
font_size 10.0
cursor_blink_interval 0.5
scrollback_lines 5000
strip_trailing_spaces smart

background_image ~/test.png
background_image_layout tiled
background_tint 0.7

Random / interesting

Waffle House Index - Wikipedia

Qutebrowser writing python userscripts

Just wrote this and put it into ~/.local/share/qutebrowser/userscripts/yank.py.

This is an userscript that allows me to escape my only problematic markdown character (|) when copying with ym:

#!/usr/bin/python3
import os

title = os.environ['QUTE_TITLE']
title = title.replace("|", "\\|")

url = os.environ['QUTE_URL']

with open(os.environ['QUTE_FIFO'], 'w') as f:
    f.write("yank inline \"[{}]({})\"".format(title, url))

Added config.bind('ym', 'spawn --userscript yank.py') to config.py

Python set environment variables

Why did I need to use with open(..) as f: in the above script and couldn’t just do os.environ['sth']='sth else'?

Taskwarrior task annotation

It took seeing qutebrowser/taskadd at master · qutebrowser/qutebrowser to learn that you can annotate tasks in taskwarrior! task 123 annotate my annotation that can be long adds a visible line with the annotation under the task that is shown whenever the task is shown. This is awesome and I should read manpages sometimes.

Keyboard layout

I should finally put it in order, especially given that I mostly don’t use the left-hand part of the left-hand typing layout, I started today by putting my ` and ~ no LALT+SHIFT+apostrophe by adding this:

key <AD01> { [ apostrophe,!quotedbl, grave, asciitilde] };

to /usr/share/X11/xkb/symbols/v4

Making Fiamma / Semantic Mediawiki alive again

{%raw%}{{=}}{%endraw%} template

Using Template:= - Wikipedia as an example, I created a page located at = - Fiamma which I can include as {%raw%}{{=}}{%endraw%} to replace URIs in parameters in my Template:B - Fiamma template. I’m not sure how would I edit all pages containing equal signs in parameters but this is a nice start. My source is Help:Template - Wikipedia, first bullet point.

Same works for |, for which there’s already the default template {%raw%}{{!}}{%endraw%}.

New javascript bookmarklets qutebrowser userscripts!

The old venerable bookmarklets I wrote about here Updated Fiamma “Add link” bookmarklet (now there are two of them!) | Я сам, соломка, чай. are as dead as it gets, I’ll write one userscript to rule them all :) Or one userscript and one vim script to expand it.

Current iteration is:

#!/usr/bin/python3
import os
from urllib.parse import quote_plus

def urlencode(string):
  return quote_plus(string)

def replace(original):
    new = original.replace("|", "-")
    return new

title = os.environ['QUTE_TITLE']
url = os.environ['QUTE_URL']

newTitle = replace(title)
newUrl = replace(url)

et = urlencode(newTitle)
eu = urlencode(newUrl)

fiammaUrl = 'https://pchr8.net/f/index.php'
url = fiammaUrl+'?title='+et+'&action=edit&preload=Template:NewLink&preloadparams[]='+eu+'&preloadparams[]='+et

with open(os.environ['QUTE_FIFO'], 'w') as f:
    f.write("open -w {}".format(url))

Pages to test this on:

Running userscript in qutebrowser

I had issues with commands executing too early, for example before the previous one has executed. So:

config.bind('B', 'spawn --userscript open_fiamma_page.py')
config.bind('T', 'hint inputs --first;; later 20 leave-mode;; later 20 open-editor')

Lastly for some reason the “later” sometimes are interpreted as starting at the same time, not from the time the last command finished executing.

Vim macros for the vimwin

(sorry)

The above changes text like:

Diensttagebuch - A purely technical blog about things I did on particular days, for future reference and search.

tag1, tag tag2, tag3

Cat1
Cat2
And a category with space

{{#set:
k=tag1, tag tag2, tag3
|+sep=, }}

[[Category: Cat1]]
[[Category: Cat2]]

{%endraw%}

For the above, jekyll had issues with utf-8 encoding and the escaped characters, so I copy-pasted them with my mouse from my terminal.

Additionally it converts the equal sign to its template, and saves-and-closes gvim.

… And with the glorious new page Waffle House Index - Wikipedia - Fiamma a new era for that wiki starts again!

This raises the question about what is the role of this blog, but I think here we’ll stick to IT stuff

Vim script omit “Pattern not found” error

..especially when writing macros that replace stuff. The magic is the e option at the end:

:%s/x/y/ge

And the vim macro / script doesn’t break anymore.

DTB Master file

Added some things to the concat.sh script, it’s even more ugly now but the resulting page is okay:

{% raw %}
echo "Concatting all existing days"
cd _posts
echo \
"---
layout: page
title: Master file
permalink: /master/
---
"\
> ../master_file.md

cat * | grep -v "layout: post" | grep -v "categories: \[" | grep -v "title:  \"Day" | grep -v "date:   20" | grep -v "\-\-\-"  >> ../master_file.md
{% endraw %}
