cleanstring

Given a string input, cleanstring will:

• Remove any leading blank/whitespace-only lines.
• Strip a prefix consisting of any amount of whitepsace followed by a pipe ("|") character.
• Remove any trailing blank/whitespace-only lines.

The purpose is to allow for clean construction of readable multiline string literals without including unnecessary whitespace or indentation.

		Steps: []*pb.Step{
			{
				Key: &pb.StepKey{
					Token: ...,
				},
				Script: &pb.UserScript{
					Type: ...,
					Schema: ...,
					Definition: cleanstring.Get(`
						|function step(input: Schema001) {
						|  if (input.state > 0) {
						|    transitionTo2(input);
						|  } else {
						|    input.state *= -1;
						|    transitionTo3(input);
						|  }
						|}
					`),
					Entrypoint: ...,
				},
			},
		}

In the example above, Steps[0].Script.Definition will be set to:

function step(input: Schema001) {
  if (input.state > 0) {
    transitionTo2(input);
  } else {
    input.state *= -1;
    transitionTo3(input);
  }
}

Using

go get github.com/kurrik/clearstring

Then use:

str := clearstring.Get(`
    |Any literal
    |which needs to be split
    |on multiple lines for readability.
`)

str will be:

Any literal
which needs to be split
on multiple lines for readability.
