does powerline works for csh

[gkamendje73]

I have powerline working with Bash. I was wondering if there is a way to configure powerline to work with CSH. Any pointer to a CSH configuration recipe would be welcome.

Hi @gkamendje73,

Indeed, there seems to be a powerline binding for tcsh, although the docs don't seem to know about that.

As to how to set that up, first please refer to https://powerline.readthedocs.io/en/latest/usage/shell-prompts.html, then in the relevant configuration file add . {repository_root}/powerline/bindings/tcsh/powerline.tcsh

In my case, I have powerline 2.8.3 installed in /usr/lib/python3.6/site-packages however the directories like /usr/lib/python3.6/site-packages/powerline/bindings/{bash,tcsh,fish} are all empty.

pip show powerline-status
Name: powerline-status
Version: 2.8.3
Summary: The ultimate statusline/prompt utility.

However, I do see the file /usr/share/powerline/tcsh/powerline.tcsh so I added source /usr/share/powerline/tcsh/powerline.tcsh in my .cshrc file. But I am not sure that this is the correct way to do it for the following two reasons:

1. I do see the following error error connecting to /run/tmux/1001/default (No such file or directory)
2. part of the prompt is garbled when I change directory as depecited in the screenshot below

Searching the docs for "tcsh" gives the following result, which might be worth a try:

In order to keep shell prompt, but avoid launching Python twice to get unused [above]. (https://powerline.readthedocs.io/en/latest/configuration/reference.html#config-themes-above) lines in tcsh $POWERLINE_NO_TCSH_ABOVE or $POWERLINE_NO_SHELL_ABOVE variable should be set.

Having said that, it could very well be that the tcsh binding got broken in the recent years without anyone noticing; you can try to have a look here https://github.com/powerline/powerline/blob/develop/powerline/bindings/tcsh/powerline.tcsh for an idea of what the binding is trying to do. Unfortunately, I am too busy right now to do some more in-depth digging myself right now, sorry.

I tried
setenv POWERLINE_NO_TCSH_ABOVE 1
as well as
setenv POWERLINE_NO_SHELL_ABOVE
before sourcing powerline.tcsh But none of them worked. I guess I need to dig more into this.
Thanks for the hint anyway.
