# Build the Soarer's Converter tools (scas, scdis, sctool) for macOS.
#
#   scas    assembles a .sc config file into the .scb binary the converter eats
#   scdis   disassembles a .scb back into .sc text
#   sctool  talks to the converter over raw HID (info/listen/read/write)
#
# Source: https://github.com/thentenaar/sctools (BSD-2-Clause).
# No Homebrew / autotools needed: scas+scdis are plain C, and sctool is built
# against the bundled hidapi macOS backend (IOKit) directly.

# Two scdis fixes for macro blocks:
#  - a macro with no meta match condition (e.g. a plain `macro F10`) aborted
#    disassembly; emit an empty match string instead.
#  - get_macrostep_metas() read past the 4-entry `metas[]` array for the high
#    meta bits, injecting garbage bytes (e.g. 0x03) whenever a step held both
#    shift and gui (the SHIFT GUI from a screenshot macro); split pairs and
#    use the 8-entry hmetas[].
