terminal not supported error with zsh and alpine

[azmeuk]

Shell: zsh 5.8

Operating system: Alpine linux 3.8

Liquidprompt version: v1.12-rc.1

Steps to Reproduce

1. Open a SSH connection to a ZSH shell with liquidprompt on a Alpine host.

Expected Behavior

I expect no error messages, and prompt colors to be displayed correctly.

Current Behavior

I get this error message at connection.

liquidprompt: terminal xterm-256color does not support foreground colors
liquidprompt: terminal xterm-256color does not support background colors
liquidprompt: terminal xterm-256color does not support foreground colors
liquidprompt: terminal xterm-256color does not support background colors

Also my prompt shows no color.

Additional context

My terminal is alacritty, but I tested with some others and the result is always the same.
I have the right terminfos installed in my remote session.

$ ls /etc/terminfo/x/
xterm  xterm-256color  xterm-color  xterm-xfree86

My local session has also alacritty + zsh + liquidprompt, and everything goes well.

I just stumbled upon #586. My local session has tput but the remote alpine session does not.

Fixed with sudo apk add ncurses to add tput support.

I'm actually going to reopen this, this specific case deserves a better error message. Thanks for the report.

[Rycieos]

Also, strange that you see the error messages twice. Any chance you are loading Liquidprompt twice?

[azmeuk]

Actually yes. Once in ~/.zshrc and once in /etc/zsh/zshrc.

I added a warning on startup if tput isn't available. Should be more obvious now what the problem is.
