Add support for downloading CSV file

[bzfwunde]

Extended plugin to provide this, by adding the options:

import=
export=:dokuwiki:media:path:where:to:write:mediafile.csv
linkname=Name of the download link to create

Thus, I changed the syntax to use '|' as delimiter between options
rather than using ' '. I feel this is "more dokuwiki" :). However,
this breaks existing dokuwiki pages that use the csv plugin to display
a CVS file, which now would have to replace the separating space (' ')
with '|import='.

The idea behind this extension is that I want to maintain a list (in
my case a member list) in dokuwiki but provide a download link to the
csv file (also for users with only read access to the page). This is
now supported as shown in the following example:

<csv|export=:media:members.csv|linkname=Download member list>
Name,Email
,
Paul,paul@email.com
Andreads,andreas@dokuwiki.org

It renders the CSV data as a DokuWiki table but adds a CSV download link
with the title "Download member list".

This is done in the following way:

When rendering the CSV data, this data is also copied to the export=
file. Finally, a link to the just generated file is provided.

In general I like the functionality but there's a couple of things I would change:

• keep spaces as separator. instead use optional double quotes around the parameter when you want to use spaces in the description
• keep the file parameter to keep backwards compatibility (import could be an alias for it)
• downloads should be supported for inline CSV data as well (see how downloadable code blocks do it)

I understand the upside that this would not render it incompatible with
the previous version. That makes parsing of the parameters so much harder. I
could no longer use explode and would actually have to start learning php :(.
Or do you have a "-aware explode function awailable anywhere I could just use?

Further, isn't space separation really uncommon for dokuwiki plugins using the
{{...}} syntax?

No problem with this one.

I think it is working. In fact, that's what I am using in my docuwiki
installation, i.e. something like:

<csv|export=:media:members.csv|linkname=Download member list>
Name,Email
,
Paul,paul@email.com
Andreads,andreas@dokuwiki.org

Or is that now what you mean?

OK, I changed to ' ' separators, wasn't so hard after all.
I also reverted back to file= instead of import=
I'm still not sure about your 3rd point. IMO this just works.

why did you close this?

[bzfwunde]

Sorry - I only started today using github. This was my misuse of the tool.

Any news on pulling this?

Any reason why you don't want to pull this? Are other changes needed?
