spacemacs/toggle-whitespace-cleanup cannot locally disable whitespace cleanup

Description :octocat:

spacemacs/toggle-whitespace-cleanup cannot locally disable whitespace cleanup

Reproduction guide :beetle:

• Set dotspacemacs-whitespace-cleanup to all and reload.
• Open a file and add some trailing whitespace.
• spacemacs/toggle-whitespace-cleanup-off
• save-buffer

Observed behaviour: :eyes: :broken_heart: The trailing whitespace is removed.

Expected behaviour: :heart: :smile: The trailing whitespace is not removed.

Well - it is expected behaviour based on value of dotspacemacs-whitespace-cleanup. If it's nil, even if you enable whitespace-cleanup locally for the buffer - the cleanup function doesn't know how to cleanup trailing whitespace i.e. whether to cleanup all, trailing or just changed and hence it doesn't cleanup anything.

What you can do currently is: set dotspacemacs-whitespace-cleanup to your expected behaviour i.e. all, trailing or changed and then toggle it (off) globally with SPC t C-S-w [(spacemacs/toggle-global-whitespace-cleanup)] and then you can turn on/off for individual buffers.

---

May be we can improve this by having default local/global value specified in case the value is nil so that if user invokes this functionality we're able to set it up appropriately. Open to discussion.

[jakemcarthur]

My desire is for it to be on by default and off for specific buffers. It seems wrong that I can't toggle it off per-buffer when I set it to all. I accept that I would have to follow the procedure you outlined to do the opposite (off by default and on for specific buffers), so that part of my original bug report should probably be removed (edit: I just did this).

[nixmaniack]

This looks like an issue then. I might look into it if I find some time later this weekend.

Hello,

I can reproduce this issue. I have dotspacemacs-whitespace-cleanup set to trailing, which adds the delete-trailing-whitespace to the global hook before-save-hook. For example, my Spacemacs has before-save-hook: (delet-trailing-whitespace spacemacs//python-sort-imports).

Then, when I try to locally disable the whitespace cleanup for a buffer by SPC t W (i.e., spacemacs/toggle-whitespace-cleanup), which basically executes (remove-hook 'before-save-hook 'delete-trailing-whitespace t). However, this fails because there is NO local hook before-save-hook from which to remove the function delete-trailing-whitespace.

Cheers, Aly

I have a similar issue on develop. I have the variable dotspacemacs-whitespace-cleanup set to 'trailing. In the markdown mode I'm unable to have double space at the end of a line (which is a line break in markdown).

After doing M-x eval-expression RET (remove-hook 'before-save-hook 'delete-trailing-whitespace) RET I'm able to save the trailing whitespaces. But after doing some edits to the buffer and saving those spaces get deleted again (funny enough before-save-hook does not hold delete-trailing-whitespace anymore).

I've been struggling to figure out how to stop suppressing trailing whitespace in markdown in spacemacs. Turns out that I had set up editorconfig to do this before I found the option in the spacemacs config. I set dotspacemacs-whitespace-cleanup nil and am just letting editorconfig handle it now. The following basic ~/.editorconfig will clean up trailing whitespace everywhere other than markdown files if you add the editorconfig package in your config.

root = true

[*]
indent_style = space
indent_size = 2
end_of_line = lf
charset = utf-8
trim_trailing_whitespace = true
insert_final_newline = true

[*.md]
trim_trailing_whitespace = false

I am still having this issue. Is there any update on it being fixed?

[chshersh]

I'm observing this issue as well. Toggling any of whitespace-cleanup hooks/actions/variables doesn't work. I'm editing code from another editor when I don't want to introduce whitespace changes.

[treymerkley]

can confirm this issue is still present.

[usq]

same issue here, have to switch to vim for whitespace changes :cry:

Came here to say this - It was editorconfig for me as well. :laughing:

I don't see any reason to think this issue has been fixed.

[lebensterben]

@GiovanH Is this still an issue on develop?

[practicalli-johnny]

I can confirm this issue on the latest commit of Spacemacs (as of today - 6ccbbcc7d develop origin/develop gnux: fix which-key prefix bug)

I add a whitespace at the end of a line in a yasnippet file I created. SPC SPC spacemacs/toggle-whitespace-cleanup SPC f s to save the file which then removes all whitespace from end of lines in the snippet buffer

The following seems to have no effect, as whitespace was still deleted

M-x eval-expression RET (remove-hook 'before-save-hook 'delete-trailing-whitespace)

How does this go unresolved for 5 years?

Just did bump into this as well I think. Did want to switch off the removal of trailing whitespace for a specific butter, but without success. My dotspacemacs-whitespace-cleanup is set to trailing.

In my case I've not found a way (yet) to disable the whitespace removal at all. Both spacemacs/toggle-gobal-whitespace-cleanup-off and spacemacs/toggle-whitespace-cleanup-off do not seem to have an effect.

[fnussbaum]

I will fix this.
