New DUMP_MULTI_LINE_LITERAL_BLOCK doesn't indent at all #17977
Description
Hi,
i've tested the new DUMP_MULTI_LINE_LITERAL_BLOCK which got into master a few days ago with eff6902. It seems it doesn't indent the literal block at all as it should.
i've used this simple example:
<?php
include 'vendor/autoload.php';
use Symfony\Component\Yaml\Yaml;
$data = ['foo' => 'bar', 'error' => "foo\nbar"];
$yaml = Yaml::dump($data, 2, 0, Yaml::DUMP_MULTI_LINE_LITERAL_BLOCK);
Yaml::parse($yaml);
while requiring "symfony/yaml": "dev-master"
the string in $yaml is:
foo: bar
error: |
foo
bar
it should be:
foo: bar
error: |
foo
bar
that's because the parser throws:
Fatal error: Uncaught exception 'Symfony\Component\Yaml\Exception\ParseException' with message 'Unable to parse at line 3 (near "foo").' in vendor/symfony/yaml/Parser.php on line 321
I don't think that it matters, but since the bug report guidelines talk about this stuff, here are some of my details:
