I used this command for a while, but ended up manually maintaining `requirements.txt`, in order to specify platform-specific dependencies.
I don't have a clear answer to dependency management; maybe a tool like `poetry` will help, but for now, this section is useless.
Saying "discards color information" probably isn't helpful, especially since it shows a warning when saving.
None of the image formats say "discards text information" anyways.
I had to blow away my virtual environment, and installing from
requirements.txt worked whereas the existing line didn't, I guess due to
the fixed version number of textual. I don't know exactly, but it seems
pretty silly to try to maintain this list of requirements separately.
The old screenshot was generated by Select All and Copy As HTML in
Ubuntu's Terminal app (using a keyboard shortcut that had to be set up
first), and post-processed using code included in screenshot.svg, which
I'm now deleting.
The new screenshot is generated using Textual's built-in SVG export.
It displays nicer, with less artifacts (seams between cells).
It doesn't need such silly explanation of the nature of the screenshot,
and was also sizing to the width of the text, so I removed the wrapper
table which was imitating (standing in for) figure/figcaption elements.
The new screenshot also includes a window border, macOS-styled, which is
a little weird since it's a remake of MS Paint (Windows software)
developed entirely on Ubuntu (Linux distro).
- This regressed due to updates in Textual 0.25.0,
because DirectoryTree now loads directory contents in a worker:
https://github.com/Textualize/textual/issues/2456
- Directory tree expansion may be more robust now, although it's using
more internals now, and it still needs timers for whatever reason.
Originally it was `paint.py`, but after switching to running as a module
(needed to use Python's relative imports for some reason) it became "-c"
when running with the `textual` CLI.
