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?

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

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 On 11 May 2012 08:57, Hans Hagen wrote:

(untested code)

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).

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:

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.

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?

that's unpredictable (inkscape is just one of the programs that can be called) ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | voip: 087 875 68 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
