Hyper: % (percent sign) showing up while using oh-my-zsh

[zlksnk]

OS: Ubuntu 17.04

It happens only for first tab opened in hyper.

[albinekb]

I have a similar bug with fish!

First tab:

Second tab (or after cmd+k):

[ppot]

This is du to the session shell invoking. Since we print the window before creating the required IPC connectors.

[zlksnk]

Can't this be cleared at start for first tab?

[ppot]

Actually no. It buffer your input and emit it once it's ready. If you type before it's complete you will have the % sign.

[zlksnk]

No, I am saying can Hyper detect that zsh is ready? Once it detects that, it clears the terminal.

[zlksnk]

Don't know how but VS Code's terminal is able to handle it

[albinekb]

VS Code uses xterm, we currently use hterm as our terminal library, that's why VS Code is better in many ways, and why we're in progress of migrating to xterm @ajitid

adding this unsetopt PROMPT_SP to my .zshrc helped
reference

[albinekb]

That's a good workaround, but I think we should fix the issue so that hyper handles the row correctly

[zlksnk]

@albinekb I'm not using Hyper at present. Is this issue resolved in Hyper 2.0?

[albinekb]

yes, fixed in v2 🎉 @ajitid

[jakubziemba]

The issue is back in version 3.0.0.

[Barben360]

The issue is back in version 3.0.0 but adding unsetopt PROMPT_SP to .zshrc seems to fix it.

[chris-c-thomas]

I've added unsetopt PROMPT_SP to my .zshrc and that fixed it. Is that the permanent solution or should this be fixed on Zeit's end?

[meatherly]

This helped me understand the problem. https://unix.stackexchange.com/a/167600

[ifyour]

version 3.0.2 same problem. 😟

# .zshrc
# fix Hyper first line precent sign

unsetopt PROMPT_SP

[imtbl]

Can also confirm that it was fixed in 2.x, but came back with 3.0.0.

Using the workaround unsetopt PROMPT_SP for now.

This is not a fix, just a workaround

[zachauten]

I'm currently seeing this issue in 3.0.2. Interestingly it shows up in the vscode integrated terminal as well.

[mikeguidry]

I think its caused by an applications stdout piping without a finish line..
my setup:
gnome terminal, ubuntu 18,
ZSH_THEME="powerlevel9k/powerlevel9k"

....
mike@i  ~  echo -n hi  ✔  10003  07:44:30
hi% mike@i  ~ 

in other words.. doing echo -n text will print 'text%' if you perform unset PROMPT_SP then you will never see the hi or text part

I just finished reading the links and this page explains it perfectly...
https://superuser.com/questions/645599/why-is-a-percent-sign-appearing-before-each-prompt-on-zsh-in-windows

If you use this configuration you will keep your lines, and get rid of the character. The character was meant to be a feature...

setopt PROMPT_CR
setopt PROMPT_SP
export PROMPT_EOL_MARK=""

[rafaelbnp]

Why is this closed? Is there a fix (not workaround)?

[rsha256]

@rafael-paiva This was a version 2 bug; a new thread was created for the new v3 bug: #3586 😀

[edsu]

Thanks for the unsetopt PROMPT_SP trick -- this suddenly became an issue for me as OS X pushed me off bash to zsh. I'd been meaning to try it for ages anyhow, and this was the nudge I needed I guess...

I have the same issue when I am not using hyper (using iTerm) but only when loading inside of TMUX... I load my ZSH session exactly the same way outside and inside the TMUX but I am getting the % only when in TMUX session ...

on the image below the right-side displays, the % after loading ZSH directly from TMUX and the left was showing the same % but after invoking ZSH again manually it's not displayed

I should have read the comment before sending my comment I am sorry ~>

PROMPT_SP
Attempt to preserve a partial line (i.e. a line that did not end with a newline) that would otherwise be covered up by the command prompt due to the PROMPT_CR option. This works by outputting some cursor-control characters, including a series of spaces, that should make the terminal wrap to the next line when a partial line is present (note that this is only successful if your terminal has automatic margins, which is typical).

When a partial line is preserved, by default you will see an inverse+bold character at the end of the partial line: a ‘%’ for a normal user or a ‘#’ for root. If set, the shell parameter PROMPT_EOL_MARK can be used to customize how the end of partial lines are shown.

NOTE: if the PROMPT_CR option is not set, enabling this option will have no effect. This option is on by default.

[fernandopasik]

It doesn't happen in the canary 3.1.0

[francogp]

I'm having this problem on the latest commits, since today. unsetopt PROMPT_SP does not fix the problem

[LabhanshAgrawal]

@francogp check the note by @Luxcium about PROMPT_CR, that might help.

[Liquidmantis]

I started seeing this recently, too. I switched to the canary channel, and it doesn't show up, but as soon as I start typing I lose my prompt and all the terminal text is invisible, so I switched back to stable.
