* 1780 - now we always reclaim local scopesKartik K. Agaram2015-07-131-2/+2
| | | | | | But still no difference in either memory footprint or in running time. This will teach me -- for the umpteenth time -- to optimize before measuring.
* 1773 - update all mu recipes to new-default-spaceKartik K. Agaram2015-07-131-2/+2
| | | | | Turns out to not affect memory utilization or run-time. At all. But still looks nicer and requires less fudging on our part.

* 1363 - rename 'integer' to 'number'Kartik K. Agaram2015-05-131-7/+7
| | | | ..now that we support non-integers.

* 1298 - better ingredient/product handlingKartik K. Agaram2015-05-071-5/+1
| | | | | | | | | | | | | | | | | | | All primitives now always write to all their products. If a product is not used that's fine, but if an instruction seems to expect too many products mu will complain. In the process, many primitives can operate on more than two ingredients where it seems intuitive. You can add or divide more than two numbers together, copy or negate multiple corresponding locations, etc. There's one remaining bit of ugliness. Some instructions like get/get-address, index/index-address, wait-for-location, these can unnecessarily load values from memory when they don't need to. Useful vim commands: %s/ingredients\[\([^\]]*\)\]/ingredients.at(\1)/gc %s/products\[\([^\]]*\)\]/products.at(\1)/gc .,$s/\[\(.\)]/.at(\1)/gc
* 1276 - make C++ version the defaultKartik K. Agaram2015-05-051-30/+32
| | | | I've tried to update the Readme, but there are at least a couple of issues.
* 690 - convention: '$' commands for debugging onlyKartik K. Agaram2015-02-011-3/+3
| | | | | | Swap printing generalized objects using arc's infrastructure to be the $-prefixed debug helper, while the erstwhile $print-key-to-host becomes the primitive print-character to host.
* 578 - switch to non-polymorphic 'print' functionsKartik K. Agaram2015-01-171-2/+2
| | | | | Also clean up various prints from last few commits. As a convention, for debugging we always print directly to host.
* 574 - printing string literals is a hack; hard-code it in for nowKartik K. Agaram2015-01-161-3/+3

* 571 - screen primitives take an explicit terminalKartik K. Agaram2015-01-151-5/+5
| | | | | | | | | | | | | | | | | This will let me swap in a fake in tests. Still hacky, though. I'm sure I'm not managing the parameter right in the chessboard app. And then there's the question of whether it should also appear as an output operand. But it's a start. And using nil to mean 'real' is a reasonable convention. If I ever need to handle multiple screens perhaps we'll have to switch to 1:literal/terminal and 2:literal/terminal, etc. But those are equally easy to guard on.
* 498 - how mu provides closuresKartik K. Agaram2015-01-021-1/+1

* 497 - strengthen the concept of 'space'Kartik K. Agaram2015-01-021-0/+33
'default-scope' is now 'default-space' 'closure-generator' is now 'next-space-generator' The connection to high-level syntax for closures is now tenuous, so we'll call the 'outer scope' the 'next space'. So, let's try to create a few sentences with all these related ideas: Names map to addresses offset from a default-space when it's provided. Spaces can be strung together. The zeroth variable points to the next space, the one that is accessed when a variable has /space:1. To map a name to an address in the next space, you need to know what function generated that space. A corollary is that the space passed in to a function should always be generated by a single function. Spaces can be used to construct lexical scopes and objects.
