fromYaml not defined

[polds]

Description

• What did you do?

Following the Parsing JSON/YAML into map variables section of the docs it recommends using the fromYaml template function to parse yaml.

• What did you expect to happen?

fromYaml should be able to read a YAML string.

• What happened instead?

I get this error:

template: resolver:1: function "fromYaml" not defined

Example Taskfile

version: '3'

tasks:
  read-yaml:
    vars:
      FILE:
        sh: cat config.yaml
      PARSED:
        ref: 'fromYaml .FILE'
    cmds:
      - echo {{ .PARSED }}

Probably an assumption made when creating the docs. For now you could use a tool like yq to convert from YAML to JSON and then use fromJson, but we should add this natively IMO.

@andreynering any objection to this going in slim-sprig? or would you prefer it directly in Task?

Yeah, I did manage to get it to work going the fromJson path doing something like this:

  helm:vendor-all:
    vars:
      FILE:
        sh: yq '.charts' charts/charts.yaml | yq -o=json
      CHARTS:
        ref: "fromJson .FILE"
    cmds:
    - for: { var: CHARTS, as: CHART }
      task: helm:vendor
      vars:
        NAME: '{{ .CHART.name }}'
        REPO: '{{ .CHART.repo }}'
        CHART: '{{ .CHART.chart }}'
        VERSION: '{{ .CHART.version }}'

@pd93 I'd say adding is Task is better because we avoid adding external dependencies to slim-sprig.
