Support screen 5.0

[zeha]

Add loadavg-screen backtick program, as %l is gone. The colors/formatting of the caption/hardstatus lines are almost the same, barring brightness on green. Some things like +b seem to no longer work as documented, so put b into each color string. % no longer seems to need the -21 (and actually break when thats present).

Additionally, screen v5 seems to put "" into the %f flags of the currently selected window, so we don't have to do it ourselves anymore. OTOH we get a useless "" in the flags of the leftmost current window display too.

Maybe we don't need screenrc_v4 at all?

openqa-tests will need new needles after this for the flags change :-/

Uh nice, thx! Would be great if we could even avoid usage/support of screenrc_v4!

So far I only noticed two issues (unless I mis-configured anything when taking over your changes into my local daily Grml ISO as of today):

1. It looks like it highlights the current window (1) until the end (2), instead of just the current window (1)?

2. The screenrc we ship via grml-live's config/files/GRMLBASE/etc/skel/.screenrc seems to fail yet (so it might also need an update with caption/hardstatus, but maybe there's even a way how to get rid of this file?):

I think the only question is if users want screenrc and/or screenrc_generic? Without the /usr/bin scripts screenrc (and thus screenrc_v4) is probably pointless?

Indeed. fixed now.

Yeah that needs an update. I guess we have this file "only" to present a blue username instead of a red user? maybe we can drop that difference?

Should close #251 when merging.

I haven't used GNU/screen for quite some time now. Is there a logic where screenrc_generic_v4 and screenrc_v4 is selected when screen 4.x is used or am I supposed to do it manually?

Not sure, if I am holding it wrong, but this is how it looks like if I apply the setting to screen (5.0.1) in Grml daily:

But to be fair, screen looks "funny" with the default settings (in the Grml daily used):

Is this how it should look like?

Again, I am not a screen-user anymore, but I think this was nice feature.

For now: Manually. There is no way in the screen config of dealing with this.

Maybe zshrc could detect and alias it, but that seems like a lot of magic.

On ISOs, you also have to fixup the screenrc installed by grml-live.

This is the effect of using the (existing) v4 config on v5. (Which is why we are here in the first place.)

fwiw, just installed a build of this mr and it's looking good so far.

(those two screens are actually two panes in my tmux-session ^_^)

Thanks, LGTM for root user, verified on Debian/testing based daily Grml ISO.

We shouldn't forget about our /etc/skel./.screenrc we ship via grml-live nowadays, as noted in #252 (comment)

I was wondering if we can do a bit of sed magic in d/rules to produce the user screenrc. grml-live can still copy it into the right place, but then we don't have two places with the almost same file. (I know I probably moved the file incl. the rest of skel to grml-live...)

@mika could you update your console blog post?

@zeha @jkirk Sure, thanks for the reminder! So we currently have wget -O .screenrc https://grml.org/console/screenrc which ends up as redirect to https://git.grml.org/f/grml-etc-core/etc/grml/screenrc_generic.

We're handling this through https://github.com/grml/grml.org/blob/master/static/console/.htaccess, and also have https://github.com/grml/grml.org/blob/master/static/scripts/grml-config.sh in place.

Should we add support for wget -O .screenrc https://grml.org/console/screenrc_v4 for the ones running older GNU screen versions, or is there any better approach we could come up with? 🤔

I think that's the best we can do :(

grml/grml.org#154 should add the redirect
