The values.yaml file of the chart will be read and evaluated automatically to provide intellisense.
Autocomplete will also work for all Named Templates defined in the any .tpl file.
Autocomplete for defined helm variables.
Compatible with Windows and Linux/Unix.
Support for custom named value files is provided (see settings section below).
Lint command to validate correct values templating and usage of NamedTemplates.
Support and autocomplete for yaml anchors and labels
The extension is compatible with the Kubernetes extension.
Working with language type yaml and helm-template.

Commands

Helm-Intellisense: Lint : This command parses the currently active document and validates that all paths(like .Values.foo.bar) point to valid values.
Helm-Intellisense: Lint Chart : Equivalent to Lint command but for all files in the chart of the file that is currently active.

Settings

Setting	Description
`helm-intellisense.customValueFileNames`	Defines list of possible files containing values (default: `values.yaml`)
`helm-intellisense.lintFileOnSave`	If set to `true` the `Helm-Intellisense: Lint` command will be executed on save (default: `true`)
`helm-intellisense.excludeFromLinting`	Define a list of filenames which should be excluded from linting. Wildcards are also possible (Example: `*.gotmpl`)

Multiple value files (overriding)

When mulitple value files are defined they are parsed from the bottom up:

"helm-intellisense.customValueFileNames": [
    "prod-values.yaml",
    "dev-values.yaml",
    "values.yaml"
]

In this case values will be overwritten/merged by dev and dev by prod. This also means that the linter will only throw an error if a certain key is not found in any of the specified files.
