Weird behavior at startup

[smorimoto]

Env

Pure:

echo $pure_version

3.1.0

Fish:

fish --version

fish, version 3.1.2

OS/distribution:

lsb_release -a

LSB Version:    1.0
Distributor ID: VoidLinux
Description:    Void Linux
Release:        rolling
Codename:       void

That doesn't look like pure :/

1. How did you install?

2. Does your config file import pure correctly?

   $EDITOR $__fish_config_dir/config.fish
   

3. What the output of:

   type fish_prompt
   

[smorimoto]

Hmm... This doesn't happen with the default fish themes. So I thought pure is the cause.

1. I installed it with the latest fisher.

2. https://github.com/smorimoto/dotfiles/blob/master/config/fish/config.fish

λ type fish_prompt
fish_prompt is a function with definition
# Defined in /home/sora/.config/fish/functions/fish_prompt.fish @ line 1
function fish_prompt
    set --local exit_code $status  # save previous exit code

    echo -e -n (_pure_prompt_beginning)  # init prompt context (clear current line, etc.)
    echo -e (_pure_prompt_first_line)  # print current path, git branch/status, command duration
    _pure_place_iterm2_prompt_mark # place iTerm shell integration mark
    echo -e -n (_pure_prompt $exit_code)  # print prompt

    set _pure_fresh_session false
end

As it seems you use lambda symbol instead of default arrow, could you describe what you expected vs what you got?

What do you get when

source /home/sora/.config/fish/functions/fish_prompt.fish 
fish_prompt

[smorimoto]

I get nothing. By the way, what I wanted to say with the GIF is that the word "fish" appears at startup.

~/src/github.com/smorimoto/dotfiles
λ source /home/sora/.config/fish/functions/fish_prompt.fish

~/src/github.com/smorimoto/dotfiles
λ fish_prompt
~/src/github.com/smorimoto/dotfiles
λ

[edouard-lopez]

Can you try to see where it comes from:

fish_trace=1 fish >/tmp/fish-debug.txt 2>&1

Then explore the content of /tmp/fish-debug.txt to find occurence of fish⏎ or whatever is print at the top.

[smorimoto]

Here is the diff for tracing with and without pure.

I don't see anything related to the pre-prompt text, maybe @faho would know what's up with this text appearing on new shell

fish⏎

[faho]

This looks like fish printing the terminal title. It seems your OS/terminal combo can't deal with it. Try removing your fish_title function.

Note that the "⏎" isn't part of the output, fish adds it later to get the prompt onto a new line. If there is no newline, it'll show up, if there is it'll be overwritten.

Also:

OS/distribution:

Distributor ID: VoidLinux

Going by the gif, this actually looks like WSL - which is an... idiosyncratic system that requires some workarounds. Mentioning it helps! (as does mentioning the terminal you use)

[smorimoto]

Oh, I removed fish_title and then it now works as expected.

[edouard-lopez]

Thanks @faho, I'm closing then

[smorimoto]

By removing $pure_symbol_title_bar_separator, fish_title works as expected, but I still don't understand the cause of this.

[smorimoto]

@faho I'm using WSL2, Windows Terminal and Void Linux. But, WSL2 is a complete Linux kernel (like Docker for Mac/Win), so everything should just works. (Well, there are some incompatibilities on WSL1, but they're strictly in Microsoft's court. They steadily fix some of these things.)

[faho]

I'm using WSL2, Windows Terminal and Void Linux. But, WSL2 is a complete Linux kernel (like Docker for Mac/Win), so everything should just works.

Well, it doesn't. In particular the terminal is still a windows thing, and it's still kinda weird and e.g. doesn't support bracketed paste.

In this case, it seems to confuse the title-bar-separator with the end of the terminal title sequence - what did you set it to?

[smorimoto]

I have not set anything for $pure_symbol_title_bar_separator. That is, the default - should be used.

[smorimoto]

It's a little weird but adding this to the configuration solves the problem.

set -gx pure_symbol_title_bar_separator "-"

[edouard-lopez]

So maybe we should change the default title bar separator as it will prevent issue for other people quite easily.

@smorimoto Do you want to submit a PR?

[smorimoto]

@edouard-lopez I opened it.
