NESFab 0.9
Overview
This release is a mix of bug fixes, features, and performance enhancements.
MapFab support and the mapfab keyword
MapFab is a new level editor designed to be used with NESFab. Its data files can be imported into NESFab using the new mapfab keyword:
mapfab(raw, "project.mapfab", "chr", "palette", "metatiles", "level")
This keyword invokes user-defined macros for each definition in the .mapfab file, allowing one to customize how the data is formatted in the game.
The new example examples/mapfab illustrates how this works.
chrrom offsets
You can now have multiple chrrom definitions. An integer following the chrrom keyword specifies what offset the data will go.
chrrom $1000
(...)
chrrom $0000
(...)
VEC types
VECs are resizeable arrays that only exist at compile time. Their syntax is similar to regular arrays (TEAs), but their length is not part of their type signature:
ct Int{} my_vec = Int{}(1,2,3,4,5) // Type{} syntax means VEC
The purpose of VECs is that they let you write compile-time functions that generate or resize arrays. Two new keywords: push and pop were added to facilitate this.
ct fn foo(Int{} in) Int{}
Int{} out = Int{}()
for U i = 0; i < len(in); i += 1
push(out, in{i})
push(out, in{i})
return out
Unlike other types arrays, VECs can be multi-dimensional.
