Thanks again for your hints.
Finally I converts my MarkDown documents in HTML with pandoc.
Cheers,

I assume that by MD you mean markdown...


indeed



No, Debian has no general virtual "markdown-viewer" package.

Unlike PDF and DjVu, Markdown is by design sloppy which has lead to a
multitude of "flavors", so I suspect it is unlikely that we can find any
common baseline that such virtual package should promise to provide.

Possibly it would make sense to define a
"commonmark-github-flavored-viewer" since that is a reasonably popular
flavor?

Here are some markdown viewers/editors currently in Debian:

  * grip
  * formiko
  * mdp
  * pampi
  * ghostwriter
  * kookbook
  * retext

Why do you ask? Because you are looking for markdown viewers or because
you are packaging one and want to declare it as such, or...?



I am asking because a software that I am currently packaging has its documents
in MarDown (GitHub flavour, I guess).

So my understanding now is that there is no point to look for a generic MD 
viewer.

Therefore I am now considering to convert them in PDF and/or HTML documents.

Cheers,
Jerome

Sorry if I was unclear: I recommend *conservative* options over *pretty 
conservative* options.  :-P

See e.g. "accurate" and "robust" at https://github.com/commonmark/cmark 
(didn't find any comparable claims at lowdown Homepage).

Use  to avoid bootstrapping being a concern.

lowdown describes itself primarily as a translator rather than a reader
(that part is already in the package description). There are indeed many
customization options with regards to disabling various features,
whether markup extension-related (Markdown, CommonMark, GFM,
MultiMarkdown, PHP Extra) or otherwise, such as --parse-no-cmark.
lowdown(1) and lowdown(5) have all the details (in the package or on the
website). I'll try to find a way to document that in the long
description in a future upload; thank you for the suggestion.

Agreed, and why I recommended lowdown as a pretty conservative and
lightweight option. cmark is a good option too; pandoc is as well, if
bootstrapping is not a concern.

There are _many_ markdown tools...

Lowdown indeed has some interesting features as interactive Markdown 
*reader* - thanks for mentioning.  Package description however does not 
mention if _always_ a superset of markdown/CommonMark is parsed or the 
tool can be told to parse conservatively as well - perhaps relevant to 
add such information to the package long description?

For *packaging* Markdown-authored documentation, where common format is 
html and plaintext, I still recommend to first consider more 
conservative and lightweight options¹, then more conservative yet heavy 
options² - i.e. only consider exciting tools when boring ones are 
unsuitable.


 - Jonas

¹ cmark is commonly regarded as one of the most conservative and 
lightweight - see e.g.  
https://github.blog/2017-03-14-a-formal-spec-for-github-markdown/

² yes pandoc is big but battle-tested and exact about which flavors are 
parsed.

I maintain "lowdown" in Debian. It supports several markup extensions
including several from GFM and CommonMark, and can output in HTML5, roff
(man/ms), LaTeX, ODF etc. It also has a terminal output mode, that can
be used to format and view Markdown documents in a pager. Upstream is at
https://kristaps.bsd.lv/lowdown/ and the package in Debian is just
"lowdown". Upstream is very responsive, so if you miss a particular
feature please file a bug (preferrably upstream, but I can also forward)

It's written in plain C and has no dependencies apart from libbsd. That
is of note, because pandoc is notorious for being hard to bootstrap
(because of Haskell) and the only other alternative I had explored for
my use case was ronn, which is in Ruby and thus also has a complicated
dependency chain. (Depending on your package, you may or may not care
about your build-dependency chain; I did.)

Faidon

It is quite common nowadays for software projects to ship at least core 
documentation in (github- or Gitlab-flavored) Markdown (or CommonMark, a 
non-sloppy spec'ed slight subset of Markdown).

As others replying here have indicated, the easiest is to ship such 
files as-is, assuming that the reader is geeky enough to read it raw.

Personally I am of the opinion that more ideally such documentation 
should be treated as a source format with two targets - html and 
plaintext - and that both those target formats should be generated 
during package build and installed with the binary package(s).

For Github-flavored Markdown I recommend to render both target formats 
using the command-line tool cmark-gfm.  Here is an example of that: 
https://salsa.debian.org/debian/doctest/-/commit/d9b848b

For most other flavors of Markdown I recommend to render using pandoc. 
Here is an example of that: 
https://salsa.debian.org/js-team/twitter-bootstrap3/-/commit/f138bf1

For Gitlab-flavored Markdown there are currently no parser in Debian, 
but depending on the actual markup used you might get away with pandoc + 
a filter (but may then give up on rendering as plaintext).  Here is an 
example of that: 
https://salsa.debian.org/matrix-team/olm/-/commit/094396d

Feel free to reach out if you need help juggling Markdown or using 
pandoc.  I am no expert, but am interested, and am in touch with the 
author if all else fails ;-)

You can likely read those with `less`.
Alternatively, software is likely to ship a build script for e.g. HTML in
which case you should use it (see
https://www.debian.org/doc/debian-policy/ch-docs.html#preferred-documentation-formats).
