Work in Progress.
EDIT 18.6.2022: Today, I have learned three things:
  • What I want is called a “Bounding Box Calculator”.
  • I hate JavaScript a little more, now
  • My own solution, so far, is crap.

I need all nodes of all paths of a linked graphical object in an SVG file. As I work with handwritten text, those objects are combinations of several paths, sometimes grouped.

The following xpath findes the node definitions from the attribute “d” of the first path...

spellcheck in qutebrowser

If you want to set a spellcheck dictionary for the running session, type
:set spellcheck.languages ['en-US'] 
:set spellcheck.languages ['en-US', 'de-DE']
:set spellcheck.languages ['en-US', 'de-DE', 'fr-FR']
for only one or several languages at once.

To persist these settings, open and add something like:
# Spellcheck
config.set('spellcheck.languages', ["en-US", "fr-FR", "de-DE"])

31/1/2022 Addition: SVG – last paragraphs added

Just when I decided to give up JPEG for storing photos on my hard-disk and upon converting some folders with Nikon raw photos (*.nef) to JPEG2000, I stumble upon a variety of new image formats which all claim to be successors of the old JPEG. But although the “Joint Photographich Expert Group” is behind most of the effort, their work has – for the time being – not met much response in mainstream software. Only JPEG-XL could be...

[vim] avoid accidental maro recording (@q)

in ~/.vimrc I note
nnoremap Q q
nnoremap q <Nop>
and no longer end up in macro-recording mode, when I forget the colon before 'q'.

Unbuffered shell-input

There are solutions on the Web.

Having read some of these, I prefer a Ruby-Oneliner “readNB” which returns the 1 character that the user has had a chance to enter on the keyboard, before readNB returns.

---------------------- In the meantime -------------------------
GazL has – in the very first comment on this blog, below – presented a better solution with the shell built-in command read: read accepts some parameters and a call like
read -r -s -N1 [VARIABLE]
