I read on the wiki that now svg is natively supported. Hmm.
I am missing a trick here:
I try
___
\starttext
Hello world
\externalfigure[ChangingField_ILUC.pdf
\stoptext
__
And all goes as expected: I get output with the expected graphic in place
But if I try
___
\starttext
Hello world
\externalfigure[ChangingField_ILUC.svg]
\stoptext
___
I get :
!LuaTeX error: cannot find image file 'm_k_i_v_ChangingField_ILUC.pdf'
==> Fatal error occurred, no output PDF file produced!
Is it time to update context? From the date of the wiki revision it
seems not, since I am on ConTeXt ver: 2011.11.29 23:11 MKIV
FWIW, I cannot find the intermediate file
'm_k_i_v_ChangingField_ILUC.pdf' on my disk either…both graphics files
are in the same location, both exist, both are named correctly….
Thanks
Ian

No. You need to have inkscape installed (and in your PATH) for svg to pdf
conversion to work.

@Hans, could we change the conversion so that it checks for inkscape and
gives a more sensible warning if inkscape is absent?

I don't know about robustness, but “which inkscape” seems to be the
candidate from my point of view for POSIX systems. The windows
equivalent would be “WHERE inkscape” according to google (untested).

How about just implementing the unix which command in lua?
(untested code)
function which(string file)
local path = os.getenv("PATH")
local splitter = lpeg.splitat(io.fileseparator)
local directories = lpeg.match(splitter, path)
for dir in directories
if io.exists(file.join(dir,file)) then
return true
end
end
return false
end

Indeed -)
It's more complicated as on windows there can be implicit 'exe', 'cmd',
'bat' suffixes but some testing shows that a path checker is faster than
calling which/where so I've added an os.[which|where] to l-os.lua that
we can use.
I've added a check to the graphic converter code but didn't test (not in
the mood to rename/remove programs and/or make a test file).

Aha,
Well, my contribution will be to adjust the wiki for simple minded
people like me…as I think my solution will be (if I decide for svg) to
batch convert these before launching the context build process.
Thanks to all

If you think the wiki needs to be updated, just go for it. I don't
know if it's the best place, but the inkscape dependency is
mentioned on the installation page:

Why? That's exactly what context does in the background. There's
generally no need to do it yourself, except if you have SVGs with
fancy effects (e.g. filters) that need a hand-tuned conversion.

The context conversion keeps track of changes in the images, so updated
images will be converted again. If you do the conversion outside of
context you need to keep track of that yourself.

Perhaps just the exit code of the inkscape call?

There is also rsvg-convert (from LibRSVG[1]) which can be faster (but in
some corner cases, as accurate as Inkscape).
