enhancement request — optional space after # for headers

[trevor]

Would it be possible to support preventing header creation without a space after #? This may make sense as a default in GFM mode?

Similar to :space_after_headers in https://github.com/vmg/redcarpet

# a header

#not a header

It couldn't be the default because it would change semantics and possibly break documents. However, a pull request for such a new option would be appreciated

[trevor]

Just to clarify — couldn't be the default for the Kramdown parser or the Kramdown GFM? (that is http://kramdown.gettalong.org/parser/gfm.html )

It seems like it should be the default for Kramdown GFM since that is how GFM is rendering above?

[gettalong]

It can't be the default for kramdown because it would possibly break documents. However, it this is considered a bug in kramdown's GFM implementation, it could certainly be fixed - but should we then add a new option? What do you think?

[trevor]

I don't know all the factors to weigh the decision. I'd add it as a general option for Kramdown, and make it the default in GFM.

[gettalong]

I don't like to add options for the kramdown parser that change the behavior of the parser but I can add this option for the GFM parser (with the default being turned off since otherwise it would break backwards compatibility except if this is considered a bug).

[trevor]

Sounds good to me, modification to the GFM parser sounds appropriate.

I'd guess it's a bug since it's not how GitHub is currently treating headers, from the example above they require the space character.

Fixed as bug with 81d5420
