Display glitch in the latest macOS homebrew build

[shawnyeager]

Describe the bug
Prior to this release, the frame around the core CPU/MEM/SWAP/etc. stats was whitespace. Now it's a misrendered character (see screenshot).

To Reproduce
Steps to reproduce the behavior:

1. Start Glances

Expected behavior
Divider characters render properly

Strange...

A first workaround is possible (remove the separators line):

[outputs]
separator=False

or a second one (change the separator to an simple ascii char):

glances --disable_unicode

But had to understand why the separator character is not display in MacOS terminal (it works fine on Linux).

Can you please open a Python terminal and copy/paste the result of the followings commands line (example on my Linux system):

On my Mac (which also exhibits the incorrectly rendered line in Glances):

[nicolargo]

Do you run Glances with sudo ?

[ChillarAnand]

I was facing the same issue in older glances.

With the latest version, I am not able to reproduce this issue. It's working fine now.

[crishoj]

Do you run Glances with sudo ?

No, as a regular user.

[nicolargo]

With the latest version, I am not able to reproduce this issue. It's working fine now.

Glances 4.0.8 displays the good separator char ?

[crishoj]

Bad separator char with Glances 4.0.8 here:

(BTW, this is iTerm 2. Good separator appears in iTerm 2 when I SSH to a Linux host though.)

[ChillarAnand]

It is working for me at least. I am using iTerm2 as well.

glances version:

[ChillarAnand]

@shawnyeager screenshot shows CPU, MEM usage on top right corner. Is it shown by some other software(not glances I guess)?

[shawnyeager]

Thanks, @nicolargo.

glances --disable-unicode (note it needs to be a -, not a _) does work.

python3 output is as follows:

❯ python3
Python 3.12.3 (main, Apr  9 2024, 08:09:14) [Clang 15.0.0 (clang-1500.3.9.4)] on darwin

This is a feature of iTerm2, unrelated to glances.

[shawnyeager]

My OP is wrt to glances running on my M2 MacBook. I do notice that ssh'ing into my Intel MacBook shows “correctly,” as below.

[RazCrimson]

@shawnyeager @crishoj

Can anyone of you try out the latest develop branch and see if the fixes work?

[crishoj]

@RazCrimson confirmed fixed in 4.2.0_beta03

[RazCrimson]

Closing issue as its fixed
