This is release 2.0.1 of flex - a beta release.
The flex distribution consists of the following files:
README This message
Changes Differences between this release and the previous one
Makefile
flexdef.h
parse.y
scan.l
ccl.c
dfa.c
ecs.c flex sources
gen.c
main.c
misc.c
nfa.c
sym.c
tblcmp.c
yylex.c
initscan.c pre-flex'd version of scan.l
flex.skel skeleton for generated scanners
flex.1 manual entry
COPYING flex's copyright
MISC miscellaneous stuff (e.g., old VMS Makefile) which
almost no one will care about
The files are packaged as a compressed shell archive, which in turn
contains seven shell archives. Create a directory where you want flex
to live, cd there, and use
uncompress flex.shar.Z
sh flex.shar
sh flex.shar.1
sh flex.shar.2
sh flex.shar.3
sh flex.shar.4
sh flex.shar.5
sh flex.shar.6
sh flex.shar.7
to extract them.
Decide where you want to keep flex.skel (suggestion: /usr/local/lib) and
move it there. Edit "Makefile" and change the definition of SKELETON_FILE
to reflect the full pathname of flex.skel.
For a System V machine, add "-DSYS_V" to CFLAGS in the Makefile.
To make flex for the first time, use:
make first_flex
which uses a pre-generated copy of the scanner whose source is in flex.
Assuming it builds successfully, you can test it using
make test
The "diff" should not show any differences.
If you're feeling adventurous, rebuild scan.c using various
combinations of FLEX_FLAGS, each time trying "make test" when
you're done. To rebuild it, do
rm scan.c
make FLEX_FLAGS="..."
where "..." is one of:
-c
-ce
-cm
-cfe
-cFe
and testing using:
make FLEX_FLAGS="..." test
Format the manual entry using
nroff -man flex.1
