add --no-meters option to hide meters directly from CLI

[serg00ns]

Closes #1744

[BenBE]

Given the "disable X" options all have uppercase short options so far, I'd suggest -H/--no-header. Else it might be a bit too close to -M, which disables the mouse support.

Keep in mind that the hideMeters option in the State object also hides the tab names.

Noticed that -H is already used, so maybe -B / --no-bars could work instead?
Happy to update if that’s okay.

Given some internal feedback (and related to the vacation season) there'll be some delay for the final decision of what the option will become. Until then, suggesting and discussing the possible option names is one task to prepare.

Another one (based on internal comments) is a possible issue with existing configuration options, which might be accidentally modified when the configuration is stored while a session with this config option is running.

IMO, either --no-meters or --no-header are the best choices (no strong preference here) as --no-bars is ambiguous with the FunctionBar, and it doesn't really capture the Meters anyway, which have many different non-Bar visuals too.

If we do this, I wonder if the 'hideFunctionBar' functionality should be exposed via a command line option as well BTW?

And the point @Explorer09 makes re the Tabs sounds like a (pre-existing) bug, no?

Finally, the man page will also need an update with this change.

Perhaps it is because too few people tested the # hotkey in htop. I only noticed that when testing the new command line option.

It's better to rebase the branch onto main rather than cross-merge it (to keep the commit history clean). Also squash the two commits into one.

I like @natoscott's comments, so I suggest to implement both --no-meters and --no-functionbar. I don't think these need short options at all as they are very "special interest". These need to be reflected in the man page as well.

BTW { echo -n "#" ; cat ; } | htop works.

[Explorer09]

It could be just me, but I think the name --no-function-bar would be better. (Separate the two words.)

[BenBE]

We might even accept both, but keep the documentation to only mention the one with the additional dash.

[BenBE]

Could you squash the last three commits into one? No need to document the journey there. ;-)

Otherwise seems good.
