'<<' in shell codeblock breaks formatting (or `>>`)

mog · February 21, 2022, 3:03am

Steps to reproduce

create a new document with the following content:

- list:
```shell
cat << EOF > /tmp/file.txt
line 1
```
this line’s formatting gets broken

indent all content between and including the ‘```’ characteres.

Expected result

The formatting of the last line “this line’s formatting gets broken” should not change

Actual result

The formatting of the last line “this line’s formatting gets broken” did change.
If one of the ‘<’ characters is removed, the formatting behaves as expected.

Steps to reproduce

Create note with two code blocks (see attachment for full test note)
obsidian-bugs-bash<<EOF.md (290 Bytes)

1.1.

cat <<EOF
Line 1
Line 2
EOF

1.2.

echo test

Put first code block inside quote block. Now formatting in edit mode is broken.
Add any non-letter character between << and EOF e.g. <<-EOF. Now formatting should be fine.

Expected result

Intended code block with <<text shouldn’t break formatting for further code blocks inside editor mode.

Actual result

Code blocks after <<text inside quoted code block will be displayed as plain text inside editor mode, it will be fine in reading mode.

Any updates on this bug? I have exactly the same issue and I think this is definitely worth fixing.
