Metadata is being transformed on gist update

original meta data

metadata after gist update

The existing metadata is being modfiied.

• I dont' think the gists data is correct in terms of sub data and indent
• It looks like empty strings aliases is turned into null
• tags and emojis are being changed. they should be array format. and emojis and others shoudl not be changed.
• dates are beign modfied

In general only gist metadata should be modified. @timrogers

Thanks for flagging this!

The indentation of the gists data looks fine to me. But it does look like the library we're using for working with YAML front-matter, gray-matter, is doing some normalization on YAML input it processes. I'm not going to have time to address this - but you would be welcome to make a contribution to fix this issue.
