[Bug]: bash: /tmp/alias_completion-23769qilp1o: line 978: unexpected EOF while looking for matching `''

[phil-markarian]

Expected behavior

source .bashrc doesn't work without errors.

Current behavior

Currently when I do source .bashrc it gives me the following error,
bash: /tmp/alias_completion-23769qilp1o: line 978: unexpected EOF while looking for matching ''`

Possible solution

No response

Context

I have a fresh install plus I have ble.sh plugin turned on and ble.sh installed.

Steps to reproduce

Install bash-it with --silent flag. Install ble.sh and then enable add-on. Do source .bashrc.

Does the problem only happen when ble.sh is enabled?

What are the outputs of the following commands?

$ alias -p
$ ls -l /tmp/alias_completion-*

[akinomyoga]

Thanks. What is the result of the following command?

$ ble/widget/display-shell-version

The temporary files seem to remain, so I think it would be easier to look into that. Could you attach the file /tmp/alias_completion-23769qilp1o here? You can copy the file to alias_completion-23769qilp1o.txt (with the filename extension .txt added) and drag & drop the file into the textarea of the GitHub interface.

Note: there seem to be many other similar files, but please make sure to choose 23769qilp1o because the other files might not have caused the problem.

What do you mean by choosing exactly? I thought that these files are autogeneriated when using any of the build in aliases.

[akinomyoga]

Thanks. I'll take a look.

What do you mean by choosing exactly?

Your ls result shows many temporary files /tmp/alias_completion-XXXXXXXXXXX where the part XXXXXXXXXXX are randomly generated. The sizes of those files seem to be different, so the file contents are different. I wanted the content of the file with XXXXXXXXXXX being exactly 23769qilp1o because that is the one you reported in your first post.

I thought that these files are autogeneriated when using any of the build in aliases.

Yes. I guess they would probably cause the same issue, but I can't say they cause the present problem 100%. Also the hint for the line number 978 in your first report cannot be applied to other files.

[phil-markarian]

Thanks. I'll take a look.

Ah, I get what you were saying now. Had a brain fart lol.

[akinomyoga]

This is an issue of the aliases completion module. The following line is causing the problem:

bash-it/completion/available/aliases.completion.bash

Line 94 in d985e4c

COMP_LINE=\${COMP_LINE/$alias_name/$alias_cmd $alias_args}

The variables $alias_cmd and $alias_args may contain an arbitrary string, but they are not properly quoted in generating the body of the dynamically defined function.

I'm not sure if it will be fixed in Bash-it because I don't see the activity of the Bash-it maintainers recent years. At least, I guess it would take months to have it fixed. If you don't use aliases module, you can disable the module by running the following command.

$ bash-it disable completion aliases

[phil-markarian]

Thanks for looking at it for me.

The variables $alias_cmd and $alias_args may contain an arbitrary string, but they are not properly quoted in generating the body of the dynamically defined function.

Hmm,I see.

At least, I guess it would take months to have it fixed.

I don't mind fixing a bug myself, but the bash-it system is kind of complex and I am not very well versed in bash yet. I'll give a crack at it and see if I can get something to work though. It doesn't really impact my productivity but it stands out haha.

[phil-markarian]

Used Claude and ChatGPT to help me get close to fixing the issue.
The issue was making sure that the single quote is escaped properly. The code below fixes the error that occurs, but this code is buggy because when I tried to type say something like ls /tmp/ it will gave a bunch of strange suggestions for some reason. Anyway, I'll add updates as I go along.

echo "function $compl_wrapper {
	local compl_word=\${2?}
	local prec_word=\${3?}
	# check if prec_word is the alias itself. if so, replace it
	# with the last word in the unaliased form, i.e.,
	# alias_cmd + ' ' + alias_args.
	if [[ \$COMP_LINE == \"\$prec_word \$compl_word\" ]]; then
		prec_word='${alias_cmd} ${alias_args//\'/\'\\\\\'\'}' 
		prec_word=\${prec_word#* }
	fi
