Support for the new Apex null-coalescing operator (Spring '24)

[pozil]

Hi @dangmai, the Spring '24 release introduces the Apex null-coalescing operator ??. It would be great to add support for this in your plugin.

I see that the Apex team recently updated the jorje parser so it looks like you could proceed with an update of your plugin. Let me know if not and I'll raise the issue with the team.

Once again, thanks a lot for your great tool.

Update from the tooling team: the new jorje JAR should be pushed near the Spring '24 release date (Feb 10-11).

[dangmai]

Awesome, thanks for letting me know about it. I'll add support for it when the new JAR is out!

Hi @dangmai, it looks like the product team released the JAR last week.

[dangmai]

Awesome! I'll most likely add support for this this weekend, thank you for the heads up!

[dangmai]

Support for the Null-Coaslescing Exression has been added and will be included in the next release. Thanks again for raising this!

[dangmai]

This has been released as part of v2.1.0.

Thank you so much!

@dangmai I installed v2.1.0, but if I try to save a file that includes the null coalescing operator, it doesn't format, and I get this error message:

No handler found for apex.jorje.data.ast.Expr$NullCoalescingExpr. Please file a bug report.

@msouther-lisc How are you running Prettier Apex? If you're running it via VSCode, did you try restarting VSCode yet?

Also, try running these commands and paste the results here:

npm ls prettier
npm ls prettier-plugin-apex

@dangmai I hadn't restarted VS Code yet when I was getting the error. After restarting VS Code, I am no longer getting the error, but I'm not getting any formatting on Apex files whatsoever (other files, e.g. JavaScript files, still work OK). It looks like Prettier is disabled when I'm on an Apex file:

There is probably a simple reason for this, but I'm not sure what I'm doing wrong.

Here is the output of the commands you requested:

$ npm ls prettier
salesforce-app@1.0.0 C:\git\salesforce-liscerp
├─┬ @prettier/plugin-xml@2.2.0
│ └── prettier@3.2.5 deduped
├─┬ prettier-plugin-apex@2.1.0
│ └── prettier@3.2.5 deduped
└── prettier@3.2.5

$ npm ls prettier-plugin-apex
salesforce-app@1.0.0 C:\git\salesforce-liscerp
└── prettier-plugin-apex@2.1.0

[dangmai]

I see - for your initial issue the reason VSCode has to be restarted when a Prettier plugin is upgraded is because of this bug on their repo prettier/prettier-vscode#3179

As for your current problem, I'm not sure what the issue is, but have you applied the workaround in this ticket yet? #1168 (comment)

[msouther-lisc]

I got it working after some trial and error. I added a new comment on the workaround thread so others can benefit from my experience.

[dangmai]

That means you upgraded from 1.13.0, here is the guide to upgrade from v1 to v2: https://github.com/dangmai/prettier-plugin-apex/wiki/Upgrading-to-Prettier-Apex-v2 Generally speaking when you upgrade a major version there'll be some manual steps you need to take.

[msouther-lisc]

Yep, you nailed it. That's exactly what the issue was there. 😝 Many thanks for your support! Much admiration for the work you do.

For anyone seeing this later the summary of what you need to do:

1. upgrade prettier to "^3.x"
2. upgrade prettier-plugin-apex to "^2.x"
3. upgrade @prettier/plugin-xml to "^3.x" (might as well)
4. add "plugins": ["prettier-plugin-apex", "@prettier/plugin-xml"] to your ".prettierrc" (prettier 3 needs this)
5. add "prettier.configPath": "./.prettierrc" to your ".vscode/settings.json" (even if it looks like it's picking up the right path in your vscode output logs)
6. restart vscode due to a known bug
