Unexpected indent

[ysmood]

var yaml = require('js-yaml');

yaml.load('|2\n  a\n  b'); // => ' a\n b\n'

It will output a\n b\n. It should output a\nb\n.

Actually, this is not a bug but intended behaviour. The top level of a YAML document is considered to be at the -1 level so that e.g. |\na\nb\n doesn't cause an error but is parsed as 'a\nb\n'. Therefore if a top-level scalar block header includes a number, it should be one more than the expected number of indentation spaces.

This behaviour also matches that of other libraries:

import YAML from 'yaml'

YAML.parse('|2\n  a\n  b') // => ' a\n b\n'

Close as not a bug
