Subject: Trailing whitespace at first EOL when dumping a hash
Download (untitled) / with headers
text/plain 354b
When dumping a hash, YAML::Syck outputs a trailing whitespace at the end of the first line, so that the first line is "--- \n". This causes various problems: trailing whitespace is invisible in most text editors; other text editors trim trailing whitespace; which ends up in tests that fail even though the output appears identical. Test file attached.
Subject: yaml-no-trailing-whitespace.t
use strict; use Test::More tests => 1; use YAML::Syck; # unlike( Dump({lou => 'is my cat'}), qr/^--- /, "no trailing whitespace after the leading '---'" );
(This is a form-reply that isn't specific to your particular report) YAML::Syck has just acquired one new maintainer (me), it still doesn't have anyone that *cares* about it. But I'm willing to help solve your report & release a new version with the fix if it's easy for me. It now has a Git repository at: If your report is a patch that fixes a problem, great. Please remake the patch against Git by forking that repo and sending me a pull request on GitHub (or an update to this bug if you prefer git-format-patch(1) or some other repo provider..). Make sure to include a test for what you fixed. If your report is some code that fails (and you have a testcase for it) a patch against the test suite to demonstrate that failure would be very useful. It's OK if the test crashes and burns, see Test::More's docs for how to make TODO tests that fail now, but shouldn't. Even if it segfaults perl C<system $^X => qw/ -Mblib -MYAML::Syck .../> or something like that and checking the return value will do.

I'm making this a wish list item. patches welcome, but otherwise I don't see this getting fixed. Any fix would have to be fully backwards compatible, which I'm not sure this would be. NOTE I also found that there's a leading space on references to duplicate items too. (&1)
