# Syntax definition for some C-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.
