String Transform GitHub Action

The function takes a string and applies one or more transformations to it.

Available transformations:

• replace (Test.String -> Test_String)
• lower (TestProject -> testproject)
• upper (TestProject -> TESTPROJECT)
• camel (TestProject -> testProject)
• kebab (TestProject -> test-project)
• pascal (testProject -> TestProject)
• snake (TestProject -> test_project)

Inputs

source (string)

Required The text that needs to be transformed.

transform (string)

One or more transformations should be applied to the source string (default is lower).

Outputs

var (string)

The resulting string after applying all transformations.

Example usage

steps:
  - name: String Transform
    id: transform
    uses: relab-services/string-transform@v1
    with:
       source: ${{ github.repository_owner }}
       transform: kebab

  - name: Print Output
    id: output
    run: echo "${{ steps.transform.outputs.var }}"

String replace

The replace transformation supports both simple string replacement and regular expression.

Simple string replacement:

steps:
  - name: String Transform
    id: transform
    uses: relab-services/string-transform@v1
    with:
       source: ${{ github.repository_owner }}
       transform: replace(".", "_")

  - name: Print Output
    id: output
    run: echo "${{ steps.transform.outputs.var }}"

Regular expression replacement:

steps:
  - name: String Transform
    id: transform
    uses: relab-services/string-transform@v1
    with:
       source: ${{ github.repository_owner }}
       transform: replace(/\W+/g, "_")

  - name: Print Output
    id: output
    run: echo "${{ steps.transform.outputs.var }}"

Combine string transformations

You can use multiple transformations simultaneously. The transformations will be applied sequentially in the order you specified.

steps:
  - name: String Transform
    id: transform
    uses: relab-services/string-transform@v1
    with:
       source: ${{ github.repository_owner }}
       transform: |
          replace(".", "-")
          kebab
          lower

  - name: Print Output
    id: output
    run: echo "${{ steps.transform.outputs.var }}"
