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 */
24 %# Macros for preproc stage.
25 m4preproc_changecom
27 %# Macros for runtime processing stage.
28 m4_changecom
29 m4_changequote
30 m4_changequote([[, ]])
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. This is to aid those who
55 %# edit the skeleton.
