Syntax highlighting and go to definition for Go template expressions inside YAML, including block scalars.
YAML has no idea what {{ }} means, so a template in a manifest renders as one flat string and a typo looks exactly like correct code. Built for Crossplane compositions using function-go-templating; Helm and Argo templates get the same treatment.
Install
code --install-extension cujarrett.gotemplate-yaml
Every YAML file is covered with no configuration.
Highlighting
Colors come from your theme. The YAML inside a template: | or values: | block is highlighted as YAML, because Crossplane go-templating and ArgoCD Helm values always hold YAML there. Other block scalars stay plain strings.
Highlighting is lexical and does not check that a template is valid.
Go to definition
Cmd+click (Ctrl+click on Windows and Linux) or F12 inside {{ }}.
| Click on |
Jumps to |
$foo |
Its := in the same template. Several declarations open a list. |
$xr.spec.parameters.foo |
The foo property in the composition's XRD. Variables are followed back to .observed.composite.resource. |
index $resources "foo" |
The resource annotated composition-resource-name: foo |
include "foo" |
Its define, in this file or any .tpl or YAML file in the workspace |
Runtime-only fields such as metadata.name have no definition to jump to.
Develop
npm ci, then just ci to lint, test and package. just run installs it locally.
