The preprocessed skeleton is translated verbatim into a +%# C array, saved as "skel.c" and compiled into the flex binary. +%# +%# 3. At runtime, the skeleton is generated and filtered (again) +%# through m4. Macros beginning with `m4_' will be processed. +%# The quoting is "[[" and "]]" so we don't interfere with +%# user code. +%# +%# All generate macros for the m4 stage contain the text "m4" or "M4" +%# in them. This is to distinguish them from CPP macros. +%# The exception to this rule is YY_G, which is an m4 macro, +%# but it needs to be remain short because it is used everywhere. +%# +/* A lexical scanner generated by flex */ + +%# Macros for preproc stage. + +%# Macros for runtime processing stage. +m4_changecom +m4_changequote +m4_changequote([[, ]]) + +%# +%# Lines in this skeleton starting with a "%" character are "control lines" +%# and affect the generation of the scanner.
