Show a message when no matching history items have been found

• [x] I have carefully read all of the instructions in this issue template.
• [x] I have carried them out to the letter.

Failure to do so can and will result in your issue being closed without warning.

Environment

print $VENDOR $OSTYPE $SHELL $ZSH_ARGZERO $ZSH_PATCHLEVEL
print -l $_autocomplete__funcfiletrace
git -C ~zsh-autocomplete log --oneline -n1

apple darwin21.0 /bin/zsh -zsh zsh-5.8.1-0-g1a490c7
/Users/<user>/.zshrc:72

• Operating system: macOS
• Terminal emulator: iTerm2

• [x] I have filled out the fields above.
• [x] I have ran the commands in the code block above.
• [x] I have pasted their output into the same block.

Steps to reproduce

cd $(mktemp -d)
git clone --depth 1 -- https://github.com/marlonrichert/zsh-autocomplete.git
> .zshrc <<EOF
PS1='%# ' PS2= RPS2='%^'; setopt transientrprompt interactivecomments
source ~/zsh-autocomplete/zsh-autocomplete.plugin.zsh
EOF
env -i HOME=$PWD PATH=$PATH TERM=$TERM ${TERMINFO:+TERMINFO=$TERMINFO} zsh -d

• [x] I have run the code block above to create a test environment.
• [x] I have reproduced my problem in this environment in the most minimal way possible.
• [ ] I have copy-pasted my entire test session into the same code block.

So, initial issue is incorrect switching between history and completion mode

Now it works that way:

• I type for example 'git' it shows history entries with git substring.
• After pressing Ctrl-R it switches to zsh-autosuggest (probably) with gray suggestion

- And after Cmd-Space it switches to another mode (I don't know it's name) with command parameters suggestion

But it should go straight to step 3 after pressing CtrlR on first step.

I can reproduce this issue using script above. But problem reproduces occasionaly

First attempt (everything works)

[marlonrichert]

How do you expect to find commands from history that start with git , if you don't have any of those in your history? But I could add a message that says something like "no matching history lines".

[underlow]

I'm afraid there's some miscommunication. Everything's ok with history. Let me describe it once again.

1. terminal starts in history mode.
2. I press CtrlR
3. I expect to see completion mode. But it's not wokring. Here is the problem.

Here is one more log: Here you can see that history works fine

same behaviour you can fine on screenshots from original post. Also as you can see from original post it works from time to time. After pressing CtrlR you can see correct behaviour as well as incorrect

git-receive-pack    git-shell           git-upload-archive  git-upload-pack
common substring: git-

Did you type a space after typing git? It looks like you haven't. That or the git (sub)command is taking a long time to complete. What happens if you type git  (with a space at the end) and then just wait a while?

[underlow]

Did you type a space after typing git? It looks like you haven't.

Yes, I dit type space, you can see it here

I've tried with another command but in isolated environment I cannot get complete suggestions at all

That or the git (sub)command is taking a long time to complete. What happens if you type git (with a space at the end) and then just wait a while?

Nothing. I've waited for several minutes

[marlonrichert]

Yes, I dit type space, you can see it here

Your earlier example showed that completion strangely enough didn’t yet notice that you had typed a space:

% git external command git-receive-pack git-shell git-upload-archive git-upload-pack common substring: git-

But now you are showing that it did notice, but gives no completions at all. What is the difference in context between these two?

Please try the following:

1. Add this to your .zshrc file after sourcing Zsh Autocomplete:

   bindkey '^Xh' _complete_help
   

2. Whenever you feel that autocompletion (incl. history search) doesn’t show the right output, press Ctrl X and then H.
3. Copy the output and paste it here.
4. Also share what was on the command line and in which position the cursor was at that moment.

[underlow]

Sorry, I've tried so many times with different settings so got messed up a bit.

But now you are showing that it did notice, but gives no completions at all. What is the difference in context between these two?

So to summarise. I try to reproduce issue in two different environments

1. my iTerm with my .zsh in regular mode. Problem reproduces every time easily.
2. isolated environment using your script. Problem reproduces 1 time of 5 tries.

in both cases problem reproduces equally, as shown on screenshots on initial post

This is output of CtrlX H on regular terminal after problem is reproduced:

I'll add info when I reproduce it on isolated env.

[underlow]

One more thing. In regular terminal if I press CtrlR and history disappears second CtlrR will not bring it back. Maybe it's related somehow.

[marlonrichert]

Can you run the test session again, try reproducing the bug until it occurs, and then share the contents of the files $_autocomplete__log, $_autocomplete__log_async and $_autocomplete__log_pty here?

[underlow]

Unfortunately cannot reproduce it anymore in test session, tried like 10 times. Would it be helpful to check these files on regular session? Problem reproduces there all the time

[marlonrichert]

Yes, please share the part of the logs corresponding to the moment the bug occurred.

[underlow]

these file are in home directory, right? right after problem is reproduced two files are empty:

[~]$ cat $_autocomplete__log
.autocomplete.async.complete.fd-widget.inner:25: completion cannot be used recursively (yet)

[~]$ cat $_autocomplete__log_async

[~]$ cat $_autocomplete__log_pty
[~]$

[marlonrichert]

@underlow Can you try to find out what in your normal config causes the bug to occur?

[underlow]

I'd love to but have no idea how. I've removed everything from .zshrc and problem still here. One thing I haven't done yet is full reinstall. If you have any idea what to check I definitely will check it

[marlonrichert]

Well, check what is the difference between your normal environment and the test environment. For example, check the output of env.

[marlonrichert]

I read your comments again and it looks like autocompletion is started correctly, but it never finishes. When the bug occurs, do you find that there are zombie zsh processes running?

[underlow]

if I have 4 terminals open, reproduce problem in one of them then top |grep zsh in another shows 4 zsh processes.

[underlow]

here is the diff between env

[marlonrichert]

How is it possible that ZSH=/Users/user/.oh-my-zsh gets set in your test environment? The shell session you pasted above did not include Oh-My-Zsh in the .zshrc file.

[underlow]

Have no idea. Sorry, but I have literally zero knowledge about any zsh internals, just copy-paste commands and outputs.

Made diff once again and there is no such line.

I've removed everything from .zshrc and problem still here.

With a completely empty .zshrc file_ (so, no Zsh Autocomplete either), what is the output of env? If you then source Zsh Autocomplete, does the problem still occur? If you then run exec zsh -l -o sourcetrace, what output do you see?

No

[underlow]

If you then source Zsh Autocomplete, does the problem still occur?

Actually yes, but in other way. I'll look for a way to make video with keys pressed and get back

[underlow]

I've checked several more times. No, problem does not appear with empty .zshrc

And the minimal config to reproduce issue is:

export ZSH=/Users/user/.oh-my-zsh

plugins=(
     zsh-autocomplete
)

source $ZSH/oh-my-zsh.sh

but it reproduces differently.

1. turn on live history zstyle ':autocomplete:*' default-context history-incremental-search-backward
2. type git a
3. press CtrlR
4. live history disappears and no completion appears
5. type d (resulting line is git ad
6. completion appears
7. delete ad and type co
8. no completion appears (but expected here)
9. press CtrlSpace
10. completion appears

I've highlighted with bold lines where I think behaviour is incorrect (items 4 and 8)

[underlow]

I've removed oz-my-zsh and reinstalled it. same behaviour as in previous post

[marlonrichert]

Thanks for the additional info. Closing this as a duplicate of #483.
