I have uploaded it to CTAN (I didn't get confirmation email yet), Hans
has updated the version on Pragma and it already proliferated to the
distribution.

Now, you should blame me. I made a backup of the old context version
(for Taco: current-backup) and updated to current (2012.05.30 11:26),
but it doesn't work at all. It says "pdfcrop failed", but my
impression is that not even the temporary folder to store the tex file
(and compile the pdf) gets generated. This issue needs Taco's help. (I
can easily revert to the old version by renaming the folder, but
sooner or later we need to upgrade the version.) I didn't touch wiki
sources at all.

Which it did, indeed. For future reference: the problem is that pdfcrop
needs
	$ pdftex file.tex

to run (using pdftex.fmt). You also updated pdftex, so the existing
format was no longer valid.

I've fixed it by creating a new pdftex.fmt.

Best wishes,
Taco

Re: Current ConTeXt & wiki

[Sietse Brouwer]

Hooray, we have a new stable!

1. Probably we should refresh the wiki's cache of <context> PNG
examples? Some examples contain commands like \contextversionnumber,
which are now stuck on 20111008 until their MD5 changes. Also,
examples might change (or break) when compiled with the new stable;
best to make that happen ourselves. Otherwise, a contributor might
make an unrelated change to the example, and the example will
unexpectedly change or break, and the contributor will think it's due
to what he/she did.

Patrick, do you know if forcing recompilation (immediate, or on page
load) is doable? Perhaps deleting a PNG wil force it to be regenerated
on page load? If it's non-trivial, I suppose we can leave it.

2. Improvement to the PHP script: make the text returned in case of
failed compilation contain a category tag like [[Category:Examples
with errors]], so that we can have a hidden maintenance category of
examples that don't compile. It would need to be added to the return
strings in the lines that match /return.*error/; if someone can send
me a current copy of wikitex.php I can take care of this. (Also, I'd
like to have a current copy so I can update
http://wiki.contextgarden.net/ConTeXt_wiki:Context_tag_implementation
)

3. On running the stable and/or the beta
Hans wrote:
> isn't the wiki running the beta then?

No, it runs the latest stable. It might be possible to have a beta
installation, too -- then users could specify <context mode=beta> --
but we'd have to look at forcing recompilation once a week (or so)
when we update the beta. Depending on Patrick's answer on the
feasibility of forcing recompilation, I could have a look at
implementing this.

Cheers,
Sietse

Another option is to use pdftrimwhite, which is part of the minimals rather than pdfcrop.

if needed I can make a mtx-trimwhite (lua instead of perl)

If you decide to rewrite pdftrimwhite, maybe you can consider making
it work with multiple page files as well. The current version only
crops the first page and discards the rest.

+1

It would be handy enough.

Btw: I didn't use/test the utility so far, but I believe it really removes the content out of the trimming area; some SW I've been using for that purpose just change the crop-box, so the content out of the trimming area reappears once you restore the cropping specification to its original value.

Best regards,

Lukas

Do you mean that it removes *white space* around the trimming area?

From my experience pdftrimwhite sometimes even removed the content
*inside* the area, so I ended up with a blank PDF and thus stopped
using it (pdfcrop was usually more reliable than pdftrimwhite).

Hello,

I mean the whatever space around the trimming area.

This out-of-trimming-area may content lines, texts, colored areas, whatever; and the intention is to remove them permanently (= unrestorable) by specifying crop-box.

Hard to so as outside stuff can have consequences for inside stuff. 
Putting stuff outside the boundingbox might even intentional.   Normally 
it boils down to clipping. Of course one can make a bitmap which can be 
clipped. It anyway depends on the tools used (often gs).
