pandoc use of embed vs img tags?

pandoc use of embed vs img tags?

[Carl Boettiger]

[-- Attachment #1: Type: text/plain, Size: 1583 bytes --]

Hi List,

If I construct a linked svg image in markdown such as:

[![Build Status](
https://travis-ci.org/cboettig/labnotebook.svg?branch=master)](https://travis-ci.org/cboettig/labnotebook
)

Pandoc seems to construct the HTML with an embed element instead of an
image element like I expected:

<a href="https://travis-ci.org/cboettig/labnotebook"><embed src="
https://travis-ci.org/cboettig/labnotebook.svg?branch=master" /></a>


It seems embed elements are not viable content for an anchor element, the
result being that the graphic is correctly displayed but cannot be clicked
on for a link, so the link text does nothing.

Why is pandoc using an embed element in this case?  (It seems to be
triggered by the presence of the query part of the link, which admittedly
means the link doesn't end in .svg, but this doesn't seem to trouble, for
instance, the github markdown parser).  Is there a way to work around this?


Thanks,

Carl

This is a bug, and should be fairly easy to fix -- just a matter
of stripping off the query before checking the image extension.

I have a similar issue with an image that used to get coded as <img>, but 
now is coded as an <embed>:

In this case pandoc sees the .aspx extension and has no way of
knowing that this is something that should be coded as img,
rather than embed, because the content could be anything.

Sorry for necro, but this is indeed a bug. John, I see where you're coming 
from, but nowadays more and more image hosting services (e.g. Imgur) no 
longer use image file name extensions in their url. Pandoc could at least 
offer an option to force them being converted to <img> insted of embed. The 
problem is that the translation to <embed> uses a different output than the 
one to <img> ... in particular, ![Imgur](http://imgur.com/blabla) puts the 
string "Imgur" into a new paragraph underneath in <p>, messing up the flow. 
Lots of manual fixes needed ...
