Starlark converter not escaping properly long strings when using --format

Drone Bugs

Apparently the starlark converter breaks long strings (80 chars?) when using --format, which leads to breaking the yaml output. For example having an unfortunate pipe (|) or other yaml element in strings which gets split produces broken/invalid yaml:

Example:

def func1():
    return [{
        'name': 'alpine',
        'image': 'docker.io/alpine:latest',
        'commands': [
                    '''echo very very very really very awesome and long lonng looonng very long bogus | grep a'''
                ],
    },]

produces:

- commands:
  - echo very very very really very awesome and long lonng looonng very long bogus
    | grep a
  image: docker.io/alpine:latest
  name: alpine

Which obviously isn’t the expected (the | on the leading line).

For this exact reason I am using pyyaml with width set to infinity. Let us know if you find a starlark native solution

From Starlark:

Starlark does not support the flag, width, and padding specifiers supported by Python’s % and other variants of C’s printf.
