Usage
Indentation will be removed from all strings tagged with dedent tag (you can also use dedent as a function, if you need to use your own tag).
expect(dedent`Line #1
Line #2
Line #3`).to.equal('Line #1\nLine #2\nLine #3');
// Leading/trailing line break is removed.
expect(
dedent`
Line #1
Line #2
Line #3
`
).to.equal('Line #1\nLine #2\nLine #3');
// No more than one leading/trailing line break is removed.
expect(
dedent`
Line #1
Line #2
Line #3
`
).to.equal('\nLine #1\nLine #2\nLine #3\n');
// Only the "base" indentation is removed.
expect(
dedent`
Line #1
Line #2
Line #3
`
).to.equal('Line #1\n\tLine #2\n\t\tLine #3');
// The last line is ignored if it doesn't contain anything else than whitespace.
expect(
function () {
return dedent`
Line #1
Line #2
Line #3
`;
}()
).to.equal('Line #1\nLine #2\nLine #3');
// Escaped characters are ignored.
expect(
dedent`
\tLine #1
\tLine #2
\tLine #3
`
).to.equal('\tLine #1\n\tLine #2\n\tLine #3');License
