module Kramdown
module Options
define(:hard_wrap, Boolean, true, <<~EOF)
Interprets line breaks literally
Insert HTML `<br />` tags inside paragraphs where the original Markdown
document had newlines (by default, Markdown ignores these newlines).
Default: true
Used by: GFM parser
EOF
define(:gfm_quirks, Object, [:paragraph_end], <<~EOF) do |val|
Enables a set of GFM specific quirks
The way how GFM is transformed on Github often differs from the way
kramdown does things. Many of these differences are negligible but
others are not.
This option allows one to enable/disable certain GFM quirks, i.e. ways
in which GFM parsing differs from kramdown parsing.
The value has to be a list of quirk names that should be enabled,
separated by commas. Possible names are:
* paragraph_end
Disables the kramdown restriction that at least one blank line has to
be used after a paragraph before a new block element can be started.
Note that if this quirk is used, lazy line wrapping does not fully
work anymore!
* no_auto_typographic
Disables automatic conversion of some characters into their
corresponding typographic symbols (like `--` to em-dash etc).
This helps to achieve results closer to what GitHub Flavored
Markdown produces.
Default: paragraph_end
Used by: GFM parser
EOF
val = simple_array_validator(val, :gfm_quirks)
val.map! { |v| str_to_sym(v.to_s) }
