flex.skl revision 1.1
1%# -*-C-*- vi: set ft=c: 2%# This file is processed in several stages. 3%# Here are the stages, as best as I can describe: 4%# 5%# 1. flex.skl is processed through GNU m4 during the 6%# pre-compilation stage of flex. Only macros starting 7%# with `m4preproc_' are processed, and quoting is normal. 8%# 9%# 2. The preprocessed skeleton is translated verbatim into a 10%# C array, saved as "skel.c" and compiled into the flex binary. 11%# 12%# 3. At runtime, the skeleton is generated and filtered (again) 13%# through m4. Macros beginning with `m4_' will be processed. 14%# The quoting is "[[" and "]]" so we don't interfere with 15%# user code. 16%# 17%# All generate macros for the m4 stage contain the text "m4" or "M4" 18%# in them. This is to distinguish them from CPP macros. 19%# The exception to this rule is YY_G, which is an m4 macro, 20%# but it needs to be remain short because it is used everywhere. 21%# 22/* A lexical scanner generated by flex */ 23 24%# Macros for preproc stage. 25m4preproc_changecom 26 27%# Macros for runtime processing stage. 28m4_changecom 29m4_changequote 30m4_changequote([[, ]]) 31 32%# 33%# Lines in this skeleton starting with a "%" character are "control lines" 34%# and affect the generation of the scanner. The possible control codes are 35%# listed and processed in misc.c. 36%# 37%# %# - A comment. The current line is omitted from the generated scanner. 38%# %if-c++-only - The following lines are printed for C++ scanners ONLY. 39%# %if-c-only - The following lines are NOT printed for C++ scanners. 40%# %if-c-or-c++ - The following lines are printed in BOTH C and C++ scanners. 41%# %if-reentrant - Print for reentrant scanners.(push) 42%# %if-not-reentrant - Print for non-reentrant scanners. (push) 43%# %if-bison-bridge - Print for bison-bridge. (push) 44%# %if-not-bison-bridge - Print for non-bison-bridge. (push) 45%# %endif - pop from the previous if code. 46%# %% - A stop-point, where code is inserted by flex. 47%# Each stop-point is numbered here and also in the code generator. 48%# (See gen.c, etc. for details.) 49%# %not-for-header - Begin code that should NOT appear in a ".h" file. 50%# %ok-for-header - %c and %e are used for building a header file. 51%# %if-tables-serialization 52%# 53%# All control-lines EXCEPT comment lines ("%#") will be inserted into 54%# the generated scanner as a C-style comment.
