# Syntax definitions for some Lua-specific patterns
#
# NOTE: this is *NOT* intended to be a complete definition of the language's
# syntax! Providing a full language grammar is overkill, because the intended
# use case is finding/replacing string patterns. This task does not require a
# full parse tree, and having one makes the task considerably more complicated.
# See the accompanying README.md for more info.
