italic html incorrectly rendered?

[fyears]

I don't know whether it should be considered a bug or a feature.

I've enabled gfm while using the marked function.

When the markdown text is:

abc_def ghi

abc_def ghi_

the html text rendered by marked is

<p>abc_def ghi</p><p>abc<em>def ghi</em></p>

But, I think the "correct" html should be:

<p>abc_def ghi</p><p>abc_def ghi_</p>

It's a conflict caused by gfm and original markdown syntax. Maybe you guys (developers of marked) should consider which result is "more correct". :-)

@chjj 👍 I support this change. It's a really basic but very important change. :)

For a possible markdown it might be wise to just escape these underscores:

abc\_def ghi\_

GitHub-flavoured Markdown has docs and they say that underscores inside words are ignored (there's a reason for that: GitHub is a coding site, and words with underscores are likely to be snake-cased identifiers from some code).

In order to imitate GFM perfectly, marked should ignore such underscores (in GFM mode) as well.

[Mithgol]

However, I have to admit (additionally) that the corresponding section of GFM docs is titled “Multiple underscores in words” and nothing is said about single underscores.

[Mithgol]

But the GitHub devs have (most probably) just forgotten to mention that single underscores are ignored in words as well as multiple underscores.

A simple test (i.e. pasting abc_def ghi_ in a GitHub comment and then hitting the “Preview” tab) shown that's indeed the case.

Closing as stale. See #956

This is still all too real, unfortunately:

bin/marked 
abc_def ghi

abc_def ghi_
^D

<p>abc_def ghi</p>
<p>abc<em>def ghi</em></p>

Closing as covered by CommonMark compliance. See #1106 and #1216.
