| %# This file is processed in several stages. |
| %# Here are the stages, as best as I can describe: |
| %# |
| %# 1. flex.skl is processed through GNU m4 during the |
| %# pre-compilation stage of flex. Only macros starting |
| %# with `m4preproc_' are processed, and quoting is normal. |
| %# |
| %# 2. 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. |
| m4preproc_changecom |
| |
| %# 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. The possible control codes are |
| %# listed and processed in misc.c. |
| %# |
| %# %# - A comment. The current line is omitted from the generated scanner. |
| %# %if-c++-only - The following lines are printed for C++ scanners ONLY. |
| %# %if-c-only - The following lines are NOT printed for C++ scanners. |
| %# %if-c-or-c++ - The following lines are printed in BOTH C and C++ scanners. |

| %# %if-bison-bridge - Print for bison-bridge. (push) |
| %# %if-not-bison-bridge - Print for non-bison-bridge. (push) |
| %# %endif - pop from the previous if code. |
| %# %% - A stop-point, where code is inserted by flex. |
| %# Each stop-point is numbered here and also in the code generator. |
| %# (See gen.c, etc. for details.) |
| %# %not-for-header - Begin code that should NOT appear in a ".h" file. |
| %# %ok-for-header - %c and %e are used for building a header file. |
