For Emacs there is already org-journal and dailies in org-roam.

Yeah well, every muggle has to go through seven circles of note-taking hell before discovering Org-mode. Nobody gets magic for free.

What I ask to a diagramming software:

- To be open source, or open specification/format.

- Easy eaditable (gui/tui/source), that is, primitives. I don't want to edit a text based diagram with a text editor (emacs artist mode).

- Free design features, so I have some control on the presentation.

- Render to text diagram as a first class feature, so it can be integrated in source code/control. From text rendering it can easily be converted to vectorial/raster.

- CLI to render.

- DSL, better with geometric (position, size) and styling features (color, bold face, ...).

I have found nothing that meets these criteria.

I'm actually using https://metacpan.org/pod/App::Asciio as the best approach.

I suggest with nice/ionice:

  ionice -c 3 nice -n 19 grep -R -e 'TREX_PID=%u' -e 'Remote VS is empty !' /

You can also check the whole drive:

  ionice -c 3 nice -n 19 grep -ab -e 'TREX_PID=%u' -e 'Remote VS is empty !' /dev/sda
