Hi,

I tried contacting the author of org-export-generic, but don't know
whether I succeeded. Since this little patch might be useful, here it
is.

I'm in the enviable situation of transforming some docs (which I've
written in org) to mediawiki (why some people enjoy using their browser
as a doc editor escapes me, but that's for another day :)

For this, I'll have to transform the "text markup" (as I'd call that)
(what org calls "emphasis"), i.e. *foo* would become **foo**, =grumble=
would become ''grumble'' and +mumble+ would become <del>mumble</del>.

You get the idea.

I've come up with a little patch which "works for me". If that seems
useful for you, please accept it; I'd be willing to beat it into shape
if you give me some advice wrt which shape is desirable :-)

Some notes:

The "translation mapping" (org markup -> target markup) lives in the
org-generic-alist under the symbol :markup, like so (this would be for
doku-wiki):

   (org-set-generic-type
      "doku-wiki"
      '(:key-binding   ?K
  [... many lines elided ...]
	:markup (("*" . "**%s**")
                ("/" . "//%s//")
                ("_" . "__%s__")
                ("=" . "''%s''")
                ("~" . "''%s''")
                ("+" . "<del>%s</del>"))))

that is, an alist mapping the (org) markup char to a (target) format
string.

I generated the patch with the -b option. Because I wrapped a
considerable chunk of code with unwind-protect, the white space noise
obscures the patch. As I don't think the patch is final, I preferred to
keep it (human) readable.

The working is fairly straightforward: it tacks the function
org-export-generic-process-markup onto the org-export-preprocess-hook
for the whole duration off org-export-generic (the unwind-protect is
there to take this function off the hook when finished). This
org-e-g-process-markup then makes a pass through the buffer (with
org-emph-re), doing its substitutions. Some fiddling was necessary since
org-emph-re matches (possibly) a bit more than strictly the marked-up
span (I think it would have been better to use zero-width assertions for
the prefix and suffix part of org-emph-re).

Patch attached.

Now the request: I tried (several times) subscribing to this list -- but
didn't succeed (I used -- or rather tried to use -- the web interface at
<http://lists.gnu.org/mailman/listinfo/emacs-orgmode>). So please keep
me in Cc, at least as long as I wrangle with the subscriptions.

If anyone has a hint as to what I could try to subscribe, I'd be glad.

Thanks again, and regards

Hi Tomas!

I have nothing to contribute to the real topic, but I wanted to inform you 
that there is a software called dokuwiki - so I got a bit irritated, whether 
you are reffering to that or to mediawiki, as you first stated.

And (at least on the mailinglist) your patch is delivered as an empty file.

Kind regards
Daniel

No, that was a typo. In my special case it's actually dokuwiki (wasn't
my choice). But the patch itself isnt dependent on that.

Whoops! thanks for the heads-up.

Here it is, inline (remember that I filtered out whitespace diffs -- the
indentation after patching isn't right, but the patch is more readable):

Usage is in my original mail.

Hi Tomás,

Could I asked you to send the patch again as an attachment of type
text/plain?  If you do so Org mode's patchtracker is able to pick it
up for further review.

Re: [PATCH] org-export-generic, " text markup" -- and a request

[Robert Goldman]

FWIW, I have a number of substantial modifications to org-export-generic that
fix its original inability to handle typefaces across line boundaries.

However, my understanding is that all patches for org-export-generic wait on Wes
Hardaker to approve them.

If this would be a good time, I can ship the patches again.

Best,

Subject: [PATCH 2/7] Make newline-handling more flexible (per WH), declare keywords.

Followed Wes Hardaker's suggestion to make the translation of
newlines more flexible --- instead of making a boolean for
special translation of blank lines, I added the ability to
specify the translation.

Also added a macro for declaring generic translation keywords
with type information and documentation.  Hope this will make
the generic translator easier to use.

Followed Wes Hardaker's idea of permitting alternative rewrites for blank
lines, instead of making the blank line handler be a boolean and
hard-wiring a newline character.

Also added a declaration form, with type and documentation options, for the
keywords used in defining a generic export method.

You succeeded...  I'm just completely out of touch for the last two
weeks and it'll continue into next week minus this very very short break
when I actually can read mail...

Anyway, I haven't read the email chain yet but if others think the patch
is fine then it may certainly be applied!

Do take your time. No impatience here.

I do hate myself how I did some things (the naming could take some
discussion. For example: "text markup" is a bad name. I don't know how
to subsume "strong", "emphasized"...). Besides, I'm unsure about this
hook-adding business within the unwind-protect. Maybe others could chime
in?

Thanks, regards

While we're at it, what's the status of my patches that add text markup
(and text markup across line boundaries) to org-export-generic.

I'm actually pretty anxious to see other patches be added before mine
goes in.  Mine had to revise the handling so that it wasn't
line-by-line, but now uses the same preprocessing as other org export
facilities.  I fear that other patches might clash with that pretty badly.

Best,
R

Hi Robert,

can you point me to that patch?  Any other testers?  Did Wes take a  
look and greed to apply it?

I have lost track and need help before I can act.

No, I'm afraid I have sent multiple emails and have heard nothing.

I don't have a good way to recruit any other testers, unfortunately.
I'm not sure how many people actually use org-generic-export; I do
because I have wikis I need to write to and I can never remember all
those oddball wiki syntaxen.

Here's a question:  what about setting up a branch on the core git repo
and letting me push that patch there?  Or you could push the patch to
the branch yourself.  That way people who are interested could test, and
those who aren't interested could just ignore it.

My patch seems really quite critical for anyone who DOES want to use
org-generic-export.  The existing generic export simply does not and
CANNOT work when markup spreads across line boundaries.  Generic export
processes the org-mode file line-by-line.  I fixed it to use the
preprocessing that is done by other org exporters, bringing together
multiple lines when there is markup (say italicization) that spreads
across line boundaries.

My next message will be a forwarding of a prior message containing the
patches.  I will send it only to you because I don't believe the mailing
list will take it.  Interested readers can find it at:

Best,

Hi Robert,

I think the best way to proceed is that I simply apply the
patch.  This is definitely the best way to get people to test it.

I would like to ask that you - at least for a while - become
the responsible person for the generic exporter.
Wes is, I guess, too busy or not interested right now.  So if
you could please look at any additional patches for he general
exporter and make a recommendation as to wether to apply them
and what changes are necessary.

I have just applied al your 7 patches and pushed the result.

Can you please get in touch with tomas@tuxteam.de and see if
and what has to be done with his patch?

Thanks, in particular for your patience.

- Carsten

I'm more than fine with letting someone else either co-manage or manage 
its development.  That means faster development to me :-)

That's fine with me.  Note that I am on vacation this week.  That's why
I haven't sent a response earlier.  I'll be mostly unavailable until the
1 September.

I have a couple of further patches to push that involve adding new
export formats based on the generic exporter (a couple of wikis).

I'll see if I can squeeze in time to do some tests (export modules are
reasonably easy to test), but that won't be for a while.

Best,
Robert

As I mentioned, I had a huge number of "away trips" in the summer and
just got over the last of my deadlines last week.  I was hoping to look
at them this week, and I apologize for the delay.

That being said, I typically prefer to take the "people intend to do
good" approach to OSS development and applying them without a more
detailed review is just fine with me Carsten.  Please don't let my
in-and-out schedule hold up others!
