Checking for b2sums lead to strange text below command line prompt

When I check for b2sums, after checking the text

(nsearch#1: << !510 >>) `'

appears below the command prompt and the keyboard doesn't work correctly.

I have to press Enter to clear the text and have the keyboard work correctly again.

Here is an example with the Arch Linux b2sums file:

Thanks. The text shown below the prompt is the indicator for the non-incremental search (nsearch - Manual §4.11). This is shown when ble.sh is in the nsearch mode. This means that you fall into the nsearch mode for some reason.

However, I do not seem to be able to reproduce the problem. I tried it in Fedora 39 and Arch Linux with random files (but haven't tried the Arch Linux ISO image suggested in the image).

• Q1: Is this problem only reproducible with the archlinux-2024.06.01-x86_64.iso in the image? Do I need to download that ISO file? Or is it reproducible with arbitrary files in your environment? For example, what is the result of the following commands?

$ echo hello > tmp.txt
$ b2sum tmp.txt > tmp.b2sum
$ b2sum --ignore-missing --check tmp.b2sum
<-- What is the behavior here?

• Q2: You seem to enable also other Bash settings in ~/.bashrc. Does the problem reproduce with the plain Bash plus ble.sh? For example,

$ cp .bash_history .bash_history.backup     # <-- back up your command history
$ INPUTRC=/dev/null bash --norc --noprofile # <-- start plain Bash session
$ source /path/to/ble.sh --norc
$ b2sum --ignore-missing --check archlinux_b2sums.txt
<-- Does the problem happen here?

After testing, command history might be truncated. You can restore the command history by running the following command:

$ cp .bash_history.backup .bash_history

• Q3: What is the result of the following command?

$ ble/debug/keylog#start
$ b2sum --ignore-missing --check archlinux_b2sums.txt
<-- Reproduce the problem here. Exit the nsearch mode by pressing RET, and proceed
$ ble/debug/keylog#end
<-- Here, the summary of the data ble.sh received is printed.

Could you provide the output of the last command?

I also can't reproduce it anymore ... well at least I learnt about non-incremental search.

Will re-open in case it happens again.

Sorry for the annoyance.

OK, no worries.
