mozilla extension - reading stdout of external process
I am trying to run dvipng
process from a thunderbird extension using Compon开发者_如何学JAVAents.interfaces.nsIProcess
. I need to read standard output of the process, but I am not able to find a way to do that. I found some threads on nsIProcess2
, but that one was (as it seems) never fully implemented with stdout. Any suggestions?
nsIProcess2
is unrelated - it was implemented but later folded into nsIProcess
. It was only about starting processes asynchronously.
The relevant bugs are bug 484246 and bug 68702. The latter has been resolved but so far that code doesn't ship with Firefox/Thunderbird by default (it's quite a bit of code that neither Firefox nor Thunderbird need themselves). So your options are:
- Build IPCModule yourself and make it part of your extension - not recommendable because it will cause lots of troubles.
- Create a native library that will call
dvipng
for you, use it via js-ctypes - should be the easiest solution. - Turn
dvipng
into a library and use it directly via js-ctypes - probably not too hard either, this will also give you better performance.
