[Feature request] Helm chart syntax highlighting support

[darthlynx]

Hi there.
I'm using WWD almost a year because of excellent Kubernetes scheme support.
It would be great to have the Helm charts syntax highlighting support too, because Helm de facto is the most common package manager for Kubernetes.

Are there any plans around this in your roadmap?

Thanks

That can be investigated. Do you have an example of Helm Chart to share? Are those Yaml files? what's their usual name patterns? Is there a schema for those somewhere?

[darthlynx]

As I know, helm uses golang template parser.

You may find more information about Helm here.

And here you may find some examples and schemes.

Please, let me know if you need anything else.
Thanks

Basically, helm charts consist of template files (.tpl) , which are still the kubernetes yaml files with the placeholders in double curly braces. The values for the placeholders should be stored in the values.yaml file

I think this would need to be supported in the https://github.com/redhat-developer/yaml-language-server used by Wild Web Developer. I've opened redhat-developer/yaml-language-server#220 to request that.
In the meantime, you could try some hack: in Preferences > General > Content-Types, browse to Text>Wild Web Developer...>JSON and add *.tpf as supported pattern. This should at least open the .yaml editor.

@mickaelistria the initial issue is about syntax highlight for helm. I think WWD should embed https://github.com/Azure/vscode-kubernetes-tools/blob/master/syntaxes/helm.tmLanguage.json

And if you see https://github.com/Azure/vscode-kubernetes-tools/blob/127ec070c8dabd56901ce13ff81bd6f561e4f087/src/yaml-support/yaml-schema.ts#L36 it uses the registerContributor of the yaml language server. It's exactly the same feature that we use for vscode-quarkus to manage our application.yaml.

To do that we need #318 and it's a work that I have started in https://github.com/angelozerr/wildwebdeveloper/tree/yaml-custom-schema

In otherwise it seems registerContributor support have 2 usecases for WWD :)

You can use my plugin https://github.com/sebthom/extra-syntax-highlighting-eclipse-plugin to get jinja and helm chart syntax highlighting.
