TERM="xterm-256color" not recognized anymore on FreeBSD

Open hsiktas opened this issue 7 years ago • 12 comments

Describe Your Issue

What is happening?

After updating the theme from 0e3c192 to b16c0d5 I get the warning message that my terminal does not support 256 colors and that I should set export TERM="xterm-256color" at the top of my ~/.zshrc. I did also update to b16c0d5 on my nearly identical Ubuntu (WSL), macOS and Termux setups and they don't show this message. Is happens as soon as I ssh into my FreeBSD server and the used terminal emulator does not seem to matter here.

Have you tried to debug or fix it?

I already added export TERM="xterm-256color" to my ~/.zshrc and it is set according to echo $TERM. Even running something like fortune | lolcat shows that 256 colors are working. The presence of the warning message seems to be an error. 🤔

I'm having the same problem with FreeBSD as well. The problem looks to be that termColors() (in functions/colors.zsh) uses 'tput colors' to get the colour capability of the terminal. Except that under FreeBSD, this seems to be returning the value for the number of columns instead. I do note that the alternative method (if tput doesn't exist) - $(echotc Co) - does return the correct number of colours available.

Anyway, all that this termColors function seems to do is just print out a warning if the terminal doesn't support 256 colours. It doesn't seem to set anything (other than a variable local to that function).

So putting in POWERLEVEL9K_IGNORE_TERM_COLORS=true into .zshrc seems to suppress that warning.

Hi,

Same problem here and the POWERLEVEL9K_IGNORE_TERM_COLORS=true solve the warning but I added some custom icons for my OS and branch: POWERLEVEL9K_FREEBSD_ICON=$'\uF3A4' POWERLEVEL9K_VCS_BRANCH_ICON=$'\uF126

and there replaced by a question mark until I run source .zshrc then the icons are correct.

The background and segments are ok before the source command, just the icons are missing.

Any idea about what going wrong?

  • FreeBSD 11.2-RELEASE-p4
  • zsh 5.6.2 (amd64-portbld-freebsd11.2)
  • version of p9k: ad14807cef372994c3ba00632117f6d43b798ffb
  • Terminal used: mate-terminal, terminator

You should always do custom settings before sourcing the theme. Check the Wiki for reference

That what I do. I source the theme after choosing my plugins and before sourcing .oh-my-zshrc/oh-my-zsh.sh script.

@jfoucry - Just to make sure I understand, you're saying you have all of that in your .zshrc, and when you start a terminal session P9k is loaded and working EXCEPT for those two icons, and then after you source your .zshrc AGAIN, the icons work?

That's right.

Juste those two icons does not work until I source again my ~/.zshrc.

@jfoucry - Well, uh, that's pretty weird. What version of P9k are you using? An official release? Can you try the next branch and let us know if it's any different?

Yes, I use an official release grab with a git clone: commit ad14807cef372994c3ba00632117f6d43b798ffb (HEAD -> master, origin/master, origin/HEAD).

I switched to next branch. after correct my .zshrc (new variable names), it's better and worst at the same time.

Instead of the OS icon, I have the "official p9k BSD icon" which is more an angry smiley with horn than the BSD icon. And the branch icon does not displayed (replaced by a question mark). To be clear, my custom icons are not used.

Here is the begin of my new .zshrc.

`TERM="xterm-256color" export TERM

When I launch my terminal (Terminator) I have some errors:

Okay, I think we should try to figure out those errors you are seeing at the end before debugging other things - if the environment isn't sane, trying to hunt down other problems is difficult.

Can you share the entirety of your zshrc? I'm wondering what might be causing those errors. If you comment out your ZSH_THEME variable to not use P9k, do you still see those errors?

bhilburn avatar Oct 30 '18 13:10 bhilburn

Sorry, I was a little bit busy.

So if I comment out ZSH_THEME I did not have those errors.

Here is my .zshrc file, I just remove aliases with password.

Due to this post:

there is no termcap capability named colors, so tput colors seems to output the nearest equivalent, which is co, the number of columns.

In my freenas jails, tput colors equals to tput co equals to 130 (which is my columns). tput Co gives 256.

But, the Co terminfo doesn't exists at my MacBook:

tput Co
tput: unknown terminfo capability 'Co'

So, maybe we have to detect OS type?

thawk avatar Jun 27 '19 13:06 thawk

I am using zsh as my shell with ohmyzsh and powerlevel9k. It complains that my terminal appears to support fewer than 256 colors and 'export TERM="xterm-256color" to the .zshrc. I set it on the top of the zshrc file but I still get the warning. when I check with tput colors, it says 80 . If I change the size of the terminal the value changes for the command tput colors.
