# Base configuration for low memory environments, see
# doc/low-memory.rst:
#
#   - Strips verbose errors etc
#   - Strips some Duktape custom feature like JX/JC; keeps e.g. RegExp
#     and other standard parts
#   - Strips some commonly unnecessary API calls like bytecode dump/load
#   - Does not enable pointer compression or external strings: these
#     need target specific support code

Add duk_uidx_t type to config headers Also: suggest DUK_USE_VALSTACK_UNSAFE for low memory. Helps with code footprint. 9 years ago
