I have been on a break from online for a few weeks, and this is not the first time I've been away like this while working on Jasonette. I've been doing this every time I needed to focus on something complicated, such as when I had to build the first Android version, design mixins, web containers, agents, etc. A lot of times being online is really a huge distraction for me when I'm trying to work on something and I completely go offline for a while to work.
When you have a question or a request, I am happy to answer whenever I can get to them, and I recommend you post them as exactly that--pure feature request or pure question--but I wonder what's the gain of posting comments like "not sure if anyone's monitoring this forum anymore".
It doesn't add any value to the post and it definitely doesn't make me excited to help.
What's sure is I am constantly working on this trying to improve things in most effective ways, some features are lower priority than others because fewer people use those features, some are more immediate and those I tend to take time to look and try to fix.
But overall, this is an open source project with an MIT license. Anyone is free to contribute to the codebase, and if you want a feature like this, you can actually suggest the feature with a suggested syntax over at https://github.com/Jasonette/Jasonette/issues, instead of just "I need this feature". Coming up with a future-proof JSON markup syntax is the hardest and most time consuming part of implementation, so when someone actually takes time to think about an issue and makes suggestions like those, I tend to appreciate those contribution immensely and get to them and provide feedback as quickly as I can. And eventually those features get reflected into the main repo.
This is something anyone can do even if they're not objective-c or Java programmers since it's just about thinking about how to express the application logic in a markup. If you don't have time or not interested in contribution, you can still post a request as Github issue too.
