Earmark does only render first link with a title of a line correctly.

[RichMorin]

A single link with a title works fine:

iex(1)> m1 = "[a link](/a_link 'a title')"        
"[a link](/a_link 'a title')"

iex(2)> Earmark.as_html(m1)
{:ok, "<p><a href=\"/a_link\" title=\"a title\">a link</a></p>\n", []}

However, a pair of links with titles (on the same line) fails:

iex(3)> m2 = "#{ m1 } #{ m1 }"
"[a link](/a_link 'a title') [a link](/a_link 'a title')"

iex(4)> Earmark.as_html(m2)
{:ok, "<p><a href=\"/a_link\" title=\"a title&#39;) [a link](/a_link &#39;a title\">a link</a></p>\n", []}

Both single links and pairs of links work ok, if no titles are used:

iex(5)> m1 = "[a link](/a_link)"          
"[a link](/a_link)"

iex(6)> Earmark.as_html(m1)
{:ok, "<p><a href=\"/a_link\">a link</a></p>\n", []}

iex(7)> m2 = "#{ m1 } #{ m1 }"
"[a link](/a_link) [a link](/a_link)"

iex(8)> Earmark.as_html(m2)
{:ok, "<p><a href=\"/a_link\">a link</a> <a href=\"/a_link\">a link</a></p>\n", []}

Some more examples

iex(24)> as_html("[a](a 't') [b](b)")
{:ok, "<p><a href=\"a\" title=\"t\">a</a> <a href=\"b\">b</a></p>\n", []}
# OK

iex(25)> as_html("[a](a 't') [b](b) [c](c 't')")
{:ok, "<p><a href=\"a\" title=\"t&#39;) [b](b) [c](c &#39;t\">a</a></p>\n", []}
# KO

iex(26)> as_html("[a](a 't') [b](b) [c](c)")
{:ok,
 "<p><a href=\"a\" title=\"t\">a</a> <a href=\"b\">b</a> <a href=\"c\">c</a></p>\n",
 []}
# OK

iex(27)> as_html("[a](a 't') [b](b) 'xxx' [c](c)")
{:ok,
 "<p><a href=\"a\" title=\"t\">a</a> <a href=\"b\">b</a> ‘xxx’ <a href=\"c\">c</a></p>\n",
 []}
# OK

iex(28)> as_html("[a](a 't') [b](b) ('xxx') [c](c)")
{:ok,
 "<p><a href=\"a\" title=\"t&#39;) [b](b) (&#39;xxx\">a</a> <a href=\"c\">c</a></p>\n",
 []}
# KO

I edited my mix.exs file as follows and the problem seems to have gone away:

  { :earmark, override: true,
      git: "https://github.com/pragdave/earmark.git" },
