smartparens not working for ' and ", () throwing error, in rmarkdown polymode about poly-r

[vspinu]

I am using smartparens but I don't recall seeing such problems. Are you sure smartparens mode gets activated in R portions in the first place? Will have a look once I am back from vacation next week.

In an .Rmd file, inside an R chunk, pressing " or ' just inserts a single character not a matched pair. A matched pair is inserted in the markdown buffer portions. In plain .R files, using ESS, matched pairs for ' and " are inserted as expected. Possibly related: inserting a parenthesis pair, () inside an R chunk generates an error: Error running timer ‘sp-show--pair-function’: (wrong-type-argument characterp nil) Again I do not see this error when inserting parenthesis in the markdown buffer portions or when using plain .R files with ESS. — You are receiving this because you are subscribed to this thread.

I would need more info on this. The exact smartparens setup and an example of the file where the problem occurs. Could you please provide this info?

[MilesMcBain]

I use Spacemacs, with no custom smartparens config of my own. I believe the guts of it is here: https://github.com/syl20bnr/spacemacs/blob/master/layers/+spacemacs/spacemacs-editing/packages.el#L254

I have found some interesting further info re reproducing the problem. If you start a new blank .Rmd buffer and insert a single r chunk ie:

```{r}
```

And type () inside the chunk you will not see an error. However once you add a second chunk, you will see the error in the first chunk only and not the second, i.e.:

```{r}
## brackets typed in here cause error
## quotes typed in here do not have match inserted
```
```{r}
## brackets typed in here do not cause error
## quotes typed in here are matched.
```

A pattern appears with n chunks, where the errors appear in all chunks except the nth (last) one in the buffer.

FYI Polymode is not part of Spacemacs, I enabled it myself using this custom layer: https://github.com/MilesMcBain/spacemacs_cfg/blob/master/private/polymode/packages.el

This is a bit complex. I have never used spacemacs or evil so it's a bit of high ramp for me. How do you add polymode layer, just put in .emacs.d? Also, is there a way to disable vim shortcuts evil layer in spacemacs?

BTW, if you have toggle-debug-on-error do you see a stacktrace?

Also, is there a way to disable vim shortcuts evil layer in spacemacs?

Nevermind about this one. It actually asks at installation startup.

Ok, I spent a bit of time with spacemacs and I am afraid I don't see this on emacs27.

This is what I do. I install spacemacs and set dotspacemacs-editing-style' to 'emacs in the .spaceemacs file. Then I add poly-R to dotspacemacs-additional-packagesand add (require 'poly-R)to thedotspacemacs/user-init`. Then I open a tmp.rmd which I attach. Nothing of what you describe happens there. Smartparens mode is enabled in that buffer.

I have discovered an issue with highlight-line mode but that's a different issue.

[MilesMcBain]

Emacs27! So you mean the master branch of the development version?

I am on 25.2.2, since I am a Debian/Ubuntu user and we're still waiting for 26 to land in the main repos. I'll try to see if I can reproduce using your steps on 25 and then 26.

[vspinu]

Ah, that's most likely it. There have been notable changes to parse-ppss in emacs 26. Your issue is almost surely related to those syntax caches. There are known issues on emacs 25 (some tests fail) but I don't have time to dig into those atm. Prefer to work for the future.

[MilesMcBain]

I can confirm the issue goes away with Emacs 26.1. I've created a PR to update the version note in the Polymode installation documentation.

[vspinu]

I am working at fixing emacs25 issues. Would you mind if I ping you a few times to check if this issue has been resolved? I have made some changes yesterday to how syntax caches are treated on e25. It might have fixed this issue.

[MilesMcBain]

I'm using the new version and it looks to be fixed on 25.2 👍

[vspinu]

Perfect. Thanks for letting me know.
