`__bp_preexec_invoke_exec "$_"` printed when running multiple commads

[clupasq]

Ctrl + X, Ctrl + E allows opening the current bash command in the default editor. I sometimes to this to enter multiple commands (separated by newline). After saving and exiting the editor, the commands are run as expected.

For the examples below I'll consider the following commands:

echo 1
echo 2
echo 3

Expected Behavior

What is expected is that only the commands and their results are being printed to the console. Here's an example of such an interaction without bash-it:

$> echo # <== at this point I fired up the editor to type in the aforementioned command(s).
echo 1
1
echo 2
2
echo 3
3

Current Behavior

Here's what's being printed when using bash-it:

❯ echo # <== using the editor to type in the commands again
echo 1
__bp_preexec_invoke_exec "$_"
1
echo 2
__bp_preexec_invoke_exec "$_"
2
echo 3
__bp_preexec_invoke_exec "$_"
3

Possible Solution

At this moment I have not looked into a solution. If other people have this issue and want it solved, I'll look into it.

Context

This is not an important bug, it's more like a nitpick.

Steps to Reproduce

1. Press Ctrl + X, Ctrl + E on the command line
2. Use the editor to enter more than one command (newline separated)
3. Save && exit
4. Inspect the output. You're likely to see the expected output, plus some __bp_preexec_invoke_exec "$_" lines between each command and its output.

Your Environment

• Bash-it version used: dev (git SHA: 2444a57 on 2021-06-10T16:04:56+03:00)

• List of enabled plugins, themes and aliases (use bash-it show (plugins/themes/aliases)): no plugins, no aliases, powerline-multiline theme (also tested with themes bobby & nwinkler and got the same result)

• bash-it doctor output:

• Bash version: 5.0.3(1)-release

• Operating System and version: Debian 10 (buster)

Your Bash Config File

  # Will provide more details if relevant. Basiclaly it's a standard bash-it config, with:
export BASH_IT_THEME='powerline-multiline'
export BASH_IT_COMMAND_DURATION=true

Hi @clupasq, sorry for the late response. What terminal do you use that allows you to edit the current command-line? I want to try and reproduce it myself

@clupasq Thanks for the report! This is an advanced usage of bash and an interesting bug you've found! I think you will need to follow this up with an issue to the rcaloras/bash-preexec library. We are embedding it into this project.

@NoahGorny I'm using mainly KDE's Konsole, but could also reproduce it in the Gnome terminal.

@cornfeedhobo Thanks, I'll post an issue there. :+1:

EDIT: I posted an issue to bash-preexec: https://github.com/rcaloras/bash-preexec/issues/116

@clupasq awesome! Thanks for following up. I'll definitely keep an eye on this. This is a really interesting corner case you've stumbled on.
