So, this is partially a continuation of this thread I made last year on request, and I would like to think this part of Snap! has been worked on further at least a little bit since then.
One request I had even was "sort of" implemented with the addition of the primitive block and being able to edit primitives - custom blocks with flat ends (i.e. you can't add more blocks after it, like the report block and the stop block) so that's cool.
For a few other things I suggested there may be a way or another around this stuff.
In my project I created basically a custom parser block that makes a couple changes to the text code that is output from codified blocks to mitigate some of the limitations.
One limitation (that I could say is still a suggestion that perhaps should be looked into) is items from custom dropdown menus - I have a simple "increment/decrement" block that is supposed to equate to a variable++ or a variable-- depending on what is chosen. You CAN type in the options dialogue something like increment=++ and decrement=-- which will then work, but then visually after selecting "increment" on the block, it changes to "++" which - so the suggestion is to simply have the option to have x=y dropdown options visually display x upon selection even if the actual value is y.
To mitigate this for now, the parser block that I created basically searches for any script line ending in increment; or decrement; changing them to ++; or --; accordingly.
But now the main issue of the thread that I believe is the more important one, one that I'm sure there is a way to mitigate but I haven't thought of a way yet. It's about some of the blocks that use the separator/delimiter options now. Mainly the operators like x+y, x*y, x = y, x > y, x < y, x and y, & x or y - they all have the arrow that you click to add another entry, which is great, but... in codification there is no (at least not yet) "per-block delimiter" so if my set delimiter is a comma , using an x+y block will result in something like 1,1.
I've been trying to get around it with things like the strings library + replace, and even using the codification blocks themselves - I think there might be a way I can change what the delimiter is depending on the block, but I'm really not sure how. Any ideas?
