Hi - I've been playing with using Pharo with Aws lambda and have got an image to launch in that environment. However now I need to better integrate Pharo with its calling environment - and I know there was a concerted effort to make Pharo play better which I should be able to leverage. So I am calling Pharo from a NodeJS wrapper (the suggested aws method for integrating alternative languages like Ruby, Go etc). I got this to work - however as an observation, it is rather awkward passing parameters to Pharo using the "eval" mechanism as other languages and environments frequently use the " character (particularly with Json) and this causes Pharo to fail if you don't \" this. I'm wondering if others have noted this and whether we can do this better somehow? For now a little nodeJS regex fu gets me past it. However my next question is about passing information back to the calling application. I can see that there is a stdout method on Fikestream that I can write to (great), however in my ./pharo eval call, which sends to a class method doing this - it also returns the result of that method or yourself? I guess this convention is great for the "eval 42 factorial" example but not so great of you just want to return some Json via stdout in a format of the calling environment? Is there something simple trick I can do to stop this extra result and just let me use stdout myself? Or do I have to return a Smalltalk string and then regex convert it to a new format in my calling language? I'm wondering if others have done this, or if anyone has some advice? It feels like a usecase that we might be able to do better somehow? Tim Sent from my iPhone
