Horizontal lines of removed chunks never go away #1715
Description
Describe the bug
Once you remove a code chunk the horizontal lines delimiting it stay.
Then I remove the # %% line:
Then I remove everything:
Also, can you add an option to completely remove those lines? They are quite invasive, specially the thick one above. Moreover, even when the cursor is not inside a chunk, the last selected one keeps being surrounded by those lines, which is very misleading.
To Reproduce
I think it's clear from the description above.
Can you fix this issue by yourself? (We appreciate the help)
No

Edit: I can reproduce with
vscode-r 3.0.0-rc.0.The issue is about code cells in .R files (specifics in #662 and #1455). See also e.g. https://code.visualstudio.com/docs/python/jupyter-support-py#_jupyter-code-cells, https://docs.spyder-ide.org/current/panes/editor.html?highlight=code+cells, or https://positron.posit.co/code-cells.html for documentation in other IDEs. This is different from code chunk in .Rmd files.
I can't reproduce withvscode-r 3.0.0-rc.0.1. open a new file (CTRL+N)2. choose rmd (CTRL+K M and choose Rmd)3. add a code chunk, e.g.:4. no borders are added and the chunk collapse when its content is removed@memeplex Please provide the exact steps, code (not screenshot only), and list of extension.@eitsupi Can you please add the "need info" tag?renkun-ken commentedon Oct 6, 2026
For code cells in
.Rfiles, the current highlightCurrentChunk() sets the top/bottom border decorations when a current chunk exists, but does not clear those decorations when no current chunk is found. Removing a chunk marker or moving outside a chunk can therefore leave the previous borders visible.That mechanism remains in
main. Keeping this open for clearing stale decorations and the requested option to disable the borders.fix: clear stale R code-cell borders and allow disabling them (REdito…
