Could you try select the line on top of the prompt to see if it's empty?

Also a different theme might work better. If so, you can adjust color by overriding conf.d/pure.fish variables in your ~/.config/fish/config.fish

Hi @edouard-lopez , I tried copy the path line to some editor and got nothing, changed a few theme and still seeing nothing. Looks like it's indeed empty.

[w3ntao]

It's working now.
I can't reproduce this bug any more...

Having exact the same problem again (with Debian/buster).

Could you try to call directly the function _pure_prompt_first_line, the one responsible to print this line:

source $__fish_config_dir/functions/_pure_prompt_first_line.fish
echo output: (_pure_prompt_first_line)

[ozelotdev]

maybe: it will be solved by installing git

How to reproduce problem

# Run docker
docker run --rm -it centos:7

# Install fish
curl --location --output /etc/yum.repos.d/shells:fish:release:3.repo https://download.opensuse.org/repositories/shells:/fish:/release:/3/CentOS_7/shells%3Afish%3Arelease%3A3.repo
yum install -y fish

# Launch fish
fish

# Install fisher
curl https://git.io/fisher --create-dirs -sLo ~/.config/fish/functions/fisher.fish

# Install pure
fisher install rafaelrinaldi/pure

I can recreate this problem by having _pure_prompt_first_line be longer than what fits in my terminal without wrapping. You can test by creating a git branch with a very long name like I do in this picture. If I then resize my terminal the prompt will show.

Maybe _pure_print_prompt should try to cut the prompt, or try to shorten the branch name if it is long. Unfortunately string sub -l $COLUMNS $prompt is not good enough. (e.g. set_color or emojis will break that approximation.) Anyone with more insight in how to cut a fish string based on rendered length?

[andreiborisov]

Unfortunately string sub -l $COLUMNS $prompt is not good enough (e.g. set_color or emojis will break that approximation).

We take into consideration ANSI colors already (see https://github.com/rafaelrinaldi/pure/blob/master/functions/_pure_string_width.fish), however, there is no way to tell the printed length beforehand exactly.

I've opened another issue to discuss this: #198.

@ozelotjp Running into this issue, installing Git solved it.

[edouard-lopez]

I'm happy to review PR for this one :)

[soredake]

I'm getting the same problem in fedora kde 36 vm with konsole.

[pauleikis]

I can confirm that I had the same issue and installing git solves it

[edouard-lopez]

Using @ozelotjp I'm able to reproduce with :

❯ echo $pure_version 
> echo 4.4.0
4.4.0

Debugging

❯ set fish_trace 1


❯ _pure_prompt_first_line
> _pure_prompt_first_line
--> if
--> type -q --no-functions git
---> return 1
--> end if

Sound like git is missing, and we aborted the whole prompt in that case and we even have a test case for that

❯ type git
> type git
type: Could not find 'git'

So installing with git probably meant you installed it, thus resolving the issue. I will update the behaviour to skip git-related prompt when it's missing from the system, there is no need to require it anyway. See #313
