VI mode eats previous prompt

[johnpneumann]

General information

• Pure version: 1.10.3
• ZSH version: 5.4.2+
• Terminal program & version: ssh
• Operating system: All
• ZSH framework: prezto and none

I have:

• Tested with another terminal program and can reproduce the issue:
• Followed the Integration instructions for my framework

Problem description

If you go quickly from command mode to insert mode, you'll consume the previous line. I tested this with prezto, as well as, just with the pure prompt (manual install).

Reproduction steps

1. Install the latest pure
2. Run set -o vi
3. Run ls -la
4. Hit esc and i in succession quickly.

My .zshrc:

# .zshrc
autoload -U promptinit; promptinit
prompt pure

Additional Information

@sindresorhus and @mafredri - I'm tagging y'all specifically because it's something worth noting. The prezto team has worked on a fix around the egregious line consumption, however, fast typers (and mechanical keyboard users) are probably going to notice this at some point. This doesn't appear to be a duplicate, however, I didn't go through closed issues. Moving on...

You can see the entire conversation in sorin-ionescu/prezto#1641 which has been tons 'o fun. ;) [to be fair it's been interesting to dig into the source and reproduce on multiple os']

Specifically see this: sorin-ionescu/prezto#1641 (comment) and sorin-ionescu/prezto#1721

I'd be happy to discuss further, but I honestly haven't dug into the pure source code enough to determine how to fix it. It appears that the issue is triggered during the async operation. I can provide the logs I've gathered if it'd be helpful.

same problem, had to temporary switch to another prompt :(

I didn't expect to see this issue pop up again - I was having a similar problem when using zsh-vi-mode .

I've since switched back to using zsh-vim-mode and I encountered this problem when trying out the pure prompt.

Just thought I'd mention it: I've seen it before.

@scresante I can't reproduce, but I can take a look at it if you can provide a repro. (PS. I do consider interop with another plugin a separate issue from this one, so feel free to open a new issue.)

[mafredri]

I can't reproduce this issue with zsh 5.9 on macOS, I'm closing this due to age (and there could be fixes to zsh that have fixed this). If it's still a problem, and reproducible with a minimal Pure setup (no plugins and up-to-date zsh), feel free to comment/reopen, if possible with more details on how to reproduce.

Edit: Similar observation here sorin-ionescu/prezto#1987 (that the issue is no longer present)

[neovimnovum]

This is an issue with zsh-vi-mode, imo. I can reproduce this issue on macOS with a fresh installation of zsh 5.9 from Homebrew. The issue goes away when zsh-vi-mode is commented out, and cannot be reproduced when it's only vanilla vi mode. The issue also goes away when pure is disabled. So my best guess is a plugin compatibility issue, just wanted to add a comment here because I've noticed it. It seems to be fixed in a recent pr.

I had this problem too, the following fixed it for me jeffreytse/zsh-vi-mode#124 (comment)
