This is a generic INSTALL file for utilities distributions.
If this package does not come with, e.g., installable documentation or
data files, please ignore the references to them below.
To compile this package:
1. Configure the package for your system. In the directory that this
file is in, type `./configure'. If you're using `csh' on an old
version of System V, you might need to type `sh configure' instead to
prevent `csh' from trying to execute `configure' itself.
The `configure' shell script attempts to guess correct values for
various system-dependent variables used during compilation, and
creates the Makefile(s) (one in each subdirectory of the source
directory). In some packages it creates a C header file containing
system-dependent definitions. It also creates a file `config.status'
that you can run in the future to recreate the current configuration.
Running `configure' takes a minute or two. While it is running, it
prints some messages that tell what it is doing. If you don't want to
see the messages, run `configure' with its standard output redirected
to `/dev/null'; for example, `./configure >/dev/null'.
To compile the package in a different directory from the one
containing the source code, you must use a version of `make' that
supports the VPATH variable, such as GNU `make'. `cd' to the directory
where you want the object files and executables to go and run
`configure'. `configure' automatically checks for the source code in
the directory that `configure' is in and in `..'. If for some reason
`configure' is not in the source code directory that you are
configuring, then it will report that it can't find the source code.
In that case, run `configure' with the option `--srcdir=DIR', where
DIR is the directory that contains the source code.
By default, `make install' will install the package's files in
/usr/local/bin, /usr/local/lib, /usr/local/man, etc. You can specify
an installation prefix other than /usr/local by giving `configure' the
option `--prefix=PATH'. Alternately, you can do so by giving a value
for the `prefix' variable when you run `make', e.g.,
make prefix=/usr/gnu
You can specify separate installation prefixes for
architecture-specific files and architecture-independent files. If
you give `configure' the option `--exec-prefix=PATH' or set the
`make' variable `exec_prefix' to PATH, the package will use PATH as
the prefix for installing programs and libraries. Data files and
documentation will still use the regular prefix. Normally, all files
are installed using the regular prefix.
Another `configure' option is useful mainly in `Makefile' rules for
updating `config.status' and `Makefile'. The `--no-create' option
figures out the configuration for your system and records it in
`config.status', without actually configuring the package (creating
`Makefile's and perhaps a configuration header file). Later, you can
run `./config.status' to actually configure the package. You can also
give `config.status' the `--recheck' option, which makes it re-run
`configure' with the same arguments you used before. This option is
useful if you change `configure'.
Some packages pay attention to `--with-PACKAGE' options to `configure',
where PACKAGE is something like `gnu-libc' or `x' (for X windows).
The README should mention any --with- options that the package recognizes.
`configure' ignores any other arguments that you give it.
If your system requires unusual options for compilation or linking
that `configure' doesn't know about, you can give `configure' initial
values for some variables by setting them in the environment. In
Bourne-compatible shells, you can do that on the command line like
this:
CC='gcc -traditional' DEFS=-D_POSIX_SOURCE ./configure
The `make' variables that you might want to override with environment
variables when running `configure' are:
(For these variables, any value given in the environment overrides the
value that `configure' would choose:)
CC C compiler program.
Default is `cc', or `gcc' if `gcc' is in your PATH.
INSTALL Program to use to install files.
Default is `install' if you have it, `cp' otherwise.
(For these variables, any value given in the environment is added to
the value that `configure' chooses:)
DEFS Configuration options, in the form `-Dfoo -Dbar ...'
Do not use this variable in packages that create a
configuration header file.
LIBS Libraries to link with, in the form `-lfoo -lbar ...'
If you need to do unusual things to compile the package, we encourage
you to figure out how `configure' could check whether to do them, and
mail diffs or instructions to the address given in the README so we
can include them in the next release.
2. Type `make' to compile the package. If you want, you can override
the `make' variables CFLAGS and LDFLAGS like this:
make CFLAGS=-O2 LDFLAGS=-s
3. If the package comes with self-tests and you want to run them,
type `make check'. If you're not sure whether there are any, try it;
if `make' responds with something like
make: *** No way to make target `check'. Stop.
then the package does not come with self-tests.
4. Type `make install' to install programs, data files, and
documentation.
5. You can remove the program binaries and object files from the
source directory by typing `make clean'. To also remove the
Makefile(s), the header file containing system-dependent definitions
(if the package uses one), and `config.status' (all the files that
`configure' created), type `make distclean'.
The file `configure.in' is used as a template to create `configure' by
a program called `autoconf'. You will only need it if you want to
regenerate `configure' using a newer version of `autoconf'.

This file, ./MISC/Amiga/README.amiga, describes the necessary steps to get
the FLEX 2.5.1 program up and running on the Commodore AMIGA with the
help of SAS/C++ 6.51 and SMake 6.50. Also it describes the contents of the
subdirectory ./MISC/Amiga, where `.' denotes the root directory of the
standard installation of FLEX 2.5.1.
FILES ADDED FOR INSTALLING FLEX 2.5.1 ON THE AMIGA
The standard distribution of FLEX 2.5.1 is assumed to be installed on
your AMIGA computer. `Installed' means that all source files from the
original archive are present in a root directory (denoted by `.' in what
follows) and, if appropriate, one or more subdirectories, on your machine.
The original source files are totally left untouched, the necessary changes
are applied in the form of `change files'. For installing FLEX 2.5.1 on
the AMIGA, several additional files come with this patch.

HOW TO INSTALL FLEX 2.5.1 ON THE AMIGA
Copy all files from ./MISC/Amiga to the root directory of the FLEX 2.5.1
distribution and edit `SMakefile' as it instructs you. There shouldn't be
too many changes necessary. Then say "make bootflex". This creates a
preliminary version of FLEX 2.5.1 without using itself.
WARNING: Don't say "make flex" yet. Any pre-2.5 version of FLEX will fail
on the file `scan.l' due to some new features only present in FLEX 2.5.
Then say "make flex". At least once the FLEX program created in the first
step will be used. To make sure that everything is alright, finally say
"make check". If you change the code, you should also say "make bigcheck"
for some more thorough testing.
When you are satisfied with the results, say "make install". This will
copy the `flex' binary, the `libfl.lib' file, and the `FlexLexer.h' header
to the paths specified in the `SMakefile'.
Finally, you should say "make clean" to remove all intermediate files from
the root directory. "make veryclean" also removes `flex' and `scan.c'.
TROUBLE SHOOTING
FLEX 2.5.1 was ported to the AMIGA and tested with the following setup:
AMIGA 2000
GVP G-Force 030/50/50/8
SAS/C++ 6.51
SED 2.05
BISON 1.22
WMERGE from the CWEB distribution
Should you encounter problems with this AMIGA patch for FLEX 2.5.1 or
should you have ideas for further improvements, like using GnuMake instead
of SMake, contact the author of this contribution

From: V61%DHDURZ1.BITNET@lbl.gov
Subject: Flex, bug fix, improvments, patches for Minix & TOS
To: vern@lbl-csam.arpa
At first I have to thank you for your wonderful program. I had ported the
old version to OS9,TOS (Atari ST) and Minix and the new version 2.1 Beta
to Minix and TOS.
While porting and using flex I detected a bug and made some improvements.
I have included a shared, compressed and uuencoded file contaning all cdiffs
and additional files (Sorry, but I'm on EBCDIC-Bitnet) and a short discussion
of the changes. Even some of the TOS specific changes might be of general
interest !
I posted these cdiffs to the minix discussion group, but I think it's up
to you to post them to the unix-sources group. If you plan to post even
the TOS compiler specific patches please contact me because there might be
further compiler (P.D.) additions. If you have an interest I could also
port the new version to OS9 -- this is a little bit more difficult, because
OS9 uses CR as end of line character (the EOL char. is coded into the
initscan.c tables,...). It is necessary to change all occurences of '\n' to
macros and variables and it's useful to add a new -n options (see commented
line in main.c)
The changes: (1.7.89 RAL)
- Bug fix: The original flex didn't like trailing spaces in exclusive start
condition lists ! If you add an trailing space to line 68 in scan.l
"%x SECT2 SECT2PROLOG SECT3 CODEBLOCK PICKUPDEF SC CARETISBOL NUM QUOTE "
you get a misleading error message:
"Syntax error at line 69: bad start condition list"
This bug can either be fixed in parse.y or in scan.l . I have chosen the
last because there the fix is minimal: Just change the rule (line 128)
"\n" to "{OPTWS}\n"
- Enhancements:
- new option "-?" that provides some help information about the other
flags (main.c)
- new option "-aTMPPATH" that allows a redefinition of the standard
path for the temporary file (this might be rather large >200k if
F,f options are selected). (main.c, flexdef.h (l.376))
- hexdump of illegal characters -- this proved to be a useful debugging
tool especialy if invisible control characters occur which weren't
covered by the rules. (scan.l fprintf statement line 129,...)
- Patches due to TOS
- General: TOS uses CR,LF as end of line char., Flex wants only a single
LF as EOL char. Therefore all I/O must be translated using f* calls.
This is done everywhere besides the YY_INPUT macro (flex.skel (scan.c),
line 31) that uses a low level 'read'. This should be definitly changed
to fread, so that all I/O calls occur on the same level.
- the short action_file_name has been "flexXXXXXX.tmp", but that's too
much for TOS,MSDOS ! I changed it to "flexXXXX.tmp" in main.c (patch
covered by the -a option additions)
- some compilers don't like external names that are ambiguous within
the first 8 characters. I defined macros that change all these long
external names to names that are unique within the first 8 characters.
Just define SHORT_EXTERNAL_NAMES to use this feature (flexdef.h)
- some statement changes that some compiler don't like:
typedef *xxx[] -> typedef **xxx (flexdef.h.,l.308)
"/*" -> '/','*' within a comment in (scan.l, l.209)
- changed short "lexyy.c" to "lex_yy.c" what's more similar to the unix
"lex.yy.c" (main.c).
- a few further really compiler dependent changes provided with
#ifdef ATARI && LATTICE res. TURBO braces.
- Additional TOS only files
- Makefile.tos: Common makefile for all TOS compilers. If you add further
ones please email me the new makefile.
- flex.lnk: Lattice - GST linker argument extension file
- flex.tlk: Turbo linker argument extension file
Additional remarks:
I didn't add a new initscan.c (= flex -ist scan.l). The current one is good
enough for a first compilation. With this first version of flex you can
rebuild your own scan.c and the final flex version !
Minix ST :
- I had to "chmem =70000 cv" (>50000) to get flex linked
- 'memset' (PC 1.3, EFTH40,...) is necessary
- chmem =90000 flex may be sufficient
Minix PC :
It should be possible to port Flex to Minix PC. The current sizes of flex
are:
Minix ST (ACK) Lattice (TOS) Turbo (TOS)
size 75300 83305 57957
compilation time 22' 15' 3'40"
flex -is scan.l 1'49" 43" 30"
The Minix ST size includes the bad generated code using only a subset of
the 68000 commands, long addresses only and a huge relocation table.
Therefore the PC size will be <64 k ! More serious is the fact that I had
to chmem =90000 flex to get scan.l converted to scan.c . But I never saw
a more complex lex source than scan.l -- so it should be possible to
reduce some array sizes without limitation for all day usage.
No one volunteered yet for a Minix PC port -- but if someone will try it
I would provide him with a new scan.c and some hints.
TOS:
Don't forget to adapt the flexskel path within flexdef.h !

Subject: Re: What is TOS
To: vern@lbl-csam.arpa
TOS is the name of the Atari ST operating system that is very similar
to MSDOS (Both use CR,LF as end of line character). Therefore I have
been astonished that no EOL convertion porblems occur within MSDOS.
I have been aware of the double buffering when changing read to fread and I
accept your argument of a possible slow down. But if you integrate the other
Atari - TOS changes, please insert a
#ifdef ATARI
fread ....
#else
read ....
#endif
in flex.skel .

echo x - Readme2

XThe changes: (1.7.89 RAL)
X
X - Bug fix: The original flex didn't like trailing spaces in exclusive start
X condition lists ! If you add an trailing space to line 68 in scan.l
X
X "%x SECT2 SECT2PROLOG SECT3 CODEBLOCK PICKUPDEF SC CARETISBOL NUM QUOTE "
X
X you get a misleading error message:
X
X "Syntax error at line 69: bad start condition list"
X
X This bug can either be fixed in parse.y or in scan.l . I have chosen the
X last because there the fix is minimal: Just change the rule (line 128)
X
X "\n" to "{OPTWS}\n"
X
X - Enhancements:
X - new option "-?" that provides some help information about the other
X flags (main.c)
X - new option "-aTMPPATH" that allows a redefinition of the standard
X path for the temporary file (this might be rather large >200k if
X F,f options are selected). (main.c, flexdef.h (l.376))
X - hexdump of illegal characters -- this proved to be a useful debugging
X tool especialy if invisible control characters occur which weren't
X covered by the rules. (scan.l fprintf statement line 129,...)
X
X - Patches due to TOS
X - General: TOS uses CR,LF as end of line char., Flex wants only a single
X LF as EOL char. Therefore all I/O must be translated using f* calls.
X This is done everywhere besides the YY_INPUT macro (flex.skel (scan.c),
X line 31) that uses a low level 'read'. This should be definitly changed
X to fread, so that all I/O calls occur on the same level.
X - the short action_file_name has been "flexXXXXXX.tmp", but that's too
X much for TOS,MSDOS ! I changed it to "flexXXXX.tmp" in main.c (patch
X covered by the -a option additions)
X - some compilers don't like external names that are ambiguous within
X the first 8 characters. I defined macros that change all these long
X external names to names that are unique within the first 8 characters.
X Just define SHORT_EXTERNAL_NAMES to use this feature (flexdef.h)
X - some statement changes that some compiler don't like:
X typedef *xxx[] -> typedef **xxx (flexdef.h.,l.308)
X "/*" -> '/','*' within a comment in (scan.l, l.209)
X - changed short "lexyy.c" to "lex_yy.c" what's more similar to the unix
X "lex.yy.c" (main.c).
X - a few further really compiler dependent changes provided with
X #ifdef ATARI && LATTICE res. TURBO braces.
X
X - Additional TOS only files
X - Makefile.tos: Common makefile for all TOS compilers. If you add further
X ones please email me the new makefile.
X - flex.lnk: Lattice - GST linker argument extension file
X - flex.tlk: Turbo linker argument extension file
X
X
XAdditional remarks:
X
XI didn't add a new initscan.c (= flex -ist scan.l). The current one is good
Xenough for a first compilation. With this first version of flex you can
Xrebuild your own scan.c and the final flex version !
X
XMinix ST :
X - I had to "chmem =70000 cv" (>50000) to get flex linked
X - 'memset' (PC 1.3, EFTH40,...) is necessary
X - chmem =90000 flex may be sufficient
X
XMinix PC :
X It should be possible to port Flex to Minix PC. The current sizes of flex
X are:
X Minix ST (ACK) Lattice (TOS) Turbo (TOS)
X
X size 75300 83305 57957
X compilation time 22' 15' 3'40"
X flex -is scan.l 1'49" 43" 30"
X
X The Minix ST size includes the bad generated code using only a subset of
X the 68000 commands, long addresses only and a huge relocation table.
X Therefore the PC size will be <64 k ! More serious is the fact that I had
X to chmem =90000 flex to get scan.l converted to scan.c . But I never saw
X a more complex lex source than scan.l -- so it should be possible to
X reduce some array sizes without limitation for all day usage.
X
X No one volunteered yet for a Minix PC port -- but if someone will try it
X I would provide him with a new scan.c and some hints.
X
XTOS:
X Don't forget to adapt the flexskel path within flexdef.h !

Subject: patches and makefile for Borland C 4.02, flex 2.4.7
To: vern@ee.lbl.gov
Date: Thu, 29 Sep 1994 10:26:42 -0400 (EDT)
X-Mailer: ELM [version 2.4 PL23]
Mime-Version: 1.0
Content-Type: text/plain; charset=US-ASCII
Content-Transfer-Encoding: 7bit
Content-Length: 9900
Enclosed are unified diffs and a makefile for Borland 4.02
The changes in the enclosed are 1) make the size parameters for memory
allocation "size_t", 2) change an include file when the lexer is
compiled within 'extern "C" {...}' in a C++ file, and 3) include pragmas
in the header suitable for BCC 4.02 to hush on warnings.
The latter is done because of the limit on command line size. A tradeoff
exists between putting pragmas in the header, or #defines in the header -
I put in the pragmas since they're suppoed to be ignored unless
understood - *and* they're enclosed in BCC specific ifdefs, anyway.
All changes are enclosed in "#ifdef __BORLANDC__".

# Makefile for flex 2.4.7 with Borland C/C++ version 4.02
#
# This will probably need to be adjusted for your existing lexer/parser
# generators. See definitions for FLEX and YACC near the bottom of the
# makefile.
#
# Copy initscan.c to scan.c to make your first executable. After that,
# you may choose to try alternate compression options for your everyday
# flex executable.
#
# This will build flex with the large model. Don't use huge, but if you
# feel like experimenting with other models, post your success stories to
# comp.compilers, OK?
#
# This makefile does *not* implement the big testing found in "makefile.in".
#
# I also assume the availability of sed and the gnu file utilities on the
# system - they're readily available, so if you don't have them, why not?
# <grin>
#
# The resulting generated lexer (the real goal, right?) will compile
# (and run nicely, too) as a .c file, as well as being included such as
# extern "C" { #include "lexyyc" } in a .cplusplus file.

# Makefile for flex 2.5.0.6 (beta) with Borland C/C++ version 4.02
#
# This will probably need to be adjusted for your existing lexer/parser
# generators. See definitions for FLEX and YACC near the bottom of the
# makefile.
#
# This makefile builds initflex.exe and flex.exe by default. It
# removes initflex.exe after making flex.exe. After that, you may
# choose to try alternate compression options for your everyday flex
# executable.
#
# This will build flex with the large model. Don't use huge, but if you
# feel like experimenting with other models, post your success stories to
# comp.compilers, OK?
#
# This makefile does *not* implement the big testing found in "makefile.in".
#
# I also assume the availability of sed and the gnu file utilities on the
# system - they're readily available, so if you don't have them, why not?
# <grin>
#
# The resulting generated lexer (the real goal, right?) will compile
# (and run nicely, too) as a .c file, as well as being included such as
# extern "C" { #include "lexyyc" } in a .cplusplus file.

Vern,
I've made flex 2.5.0.6 successfully with no changes to the source
code at all. I'm including the Borland 4.02 makefile and config.h
at the end of this message.
When you're ready for release, I'll be happy to take care of getting
the appropriate archive files up to Simtel if you wish.
I have not used this version for any of my "work-related" scanners
yet, but have run the fastwc benchmark. The compiles were for large
memory model and optimization for fastest possible code. The test
machine was a Pentium-90 (hey! timing output was integer!) with
enhanced IDE on a PCI bus and no file system caching. I ran the
test on two different input files.
(Times are in seconds.)
The first input was a typical postscript file concatenated 10 times;
by typical, I mean that there were relatively few spaces, lots of lines
with no space, using lots of parentheses.

I have no problem at all with being a contact for advice

filing the message under /MISC/AS400 is more appropriate.
The port was an interesting, very educational experience.
Thanks again.

I came in late on this discussion - I don't follow comp.compilers very
closely these days because my job has shifted somewhat.
I ported (quite some time ago) flex 2.3.6 to an IBM 3090 under MVS, using
the SAS C compiler. The approach I used was, as Vern suggested, was to
translate the tables to reflect EBCDIC-based indices. I haven't even
downloaded flex 2.4 yet, so I don't know what's in the current distribution.
My patches were in the flex 2.3 distribution for a while in the MISC
directory. If you want any more info feel free to drop me a line - I still
have (somewhere) the patches that I created from version 2.3.6.

I've built a context diff file which is ~850 lines.
Summary of major changes necessary:
o a new initscan.c -- because MVS is ebcdic, the initial scanner had
to be changed. I built a scanner from scan.l using -Ce, then
hand-manipulated the yy_ec table to fit EBCDIC instead of ASCII
chars. (This is not included in the diff file above.)
o changes in main and flexdef.h to change how files are handled. (No
dynamic file names, etc.)
o Some lines had to be shortened to 80 bytes. This mostly impacted
your RCSID lines, which with the full path name were too long.
o SASC and the linker don't allow externals to be longer than 8 chars.
I thus wrote a Q&D program to shorten all externals. (This would be
a separate file 'fixit.l', which is not included in the diffs.)
o There are several places where there are tests for 'isascii' (which I
deleted conditionally, using #ifdefs), and tests for 'A' <= x <= 'Z'
which I changed to 'isupper'.
Many of the changes I've incorporated without impacting other systems.
Others are with 'ifdefs'. Still others (the short external names and new
initscan) are 'isolable' as separate files which would have to be
included with a distribution.
Obviously, you are not going to want to (even if you can :-) ) worry about
testing new versions in the MVS environment. Likewise, I don't have the
time or resources to provide much support. (I'm not sure my management
would allow any :-( )
With all of the above feel free to say "Thanks, but no thanks." If you
want to see the diffs anyway, I will certainly mail them.
Thanks for your time and efforts.

Thank you! What you propose is okay. I might suggest, however, that you
look in the diffs for dfa.c, misc.c, and yylex.c, and consider removing
some of the ASCIIisms which are probably unnecessary. The manner in
which I made the changes was pure brute force, and there might be a
better way, but the changes I made there shouldn't hurt anything.
regards,
Steve

Sorry about the trailing blank problem. It's farily common with data sent
through bitnet paths, but ever the optimist ...
>I think there should be an 'M' at the beginning of the second line.
This isn't a problem. I believe that the first byte of the line indicates
it's length (in some manner).
Rather than re-send the data, how about a uudecode that compensates for
the trailing blank problem? I manually mangled the uuencoded file and ran
the following decode, and it seemed to work.
#! /bin/sh
# This is a shell archive. Remove anything before this line, then feed it
# into a shell via "sh file" or similar. To overwrite existing files,
# type "sh file -c".
# The tool that generated this appeared in the comp.sources.unix newsgroup;

These patches and supplemental programs should allow porting to MVS or MVS/XA
in an EBCDIC envrionment, using SAS C V4.00C.
Included are:
-rw-r--r-- 1 swl26 1573 Jul 17 14:32 README
-rw-rw-r-- 1 swl26 20861 Jul 17 13:41 diffs
-rw-rw-r-- 1 swl26 5022 Jul 17 14:00 fixit.l
-rw-rw-r-- 1 swl26 97644 Jul 17 13:42 initscan.mvs.c
-rw-rw-r-- 1 swl26 4898 Jul 17 14:08 unfixit.l
The file "diffs" contains context diffs for changes to flex 2.3.
The file "fixit.l" contains flex sources for a program to shorten external
variable and function names to 8 characters or less. This is required for the
"dumb" compiler linker used.
The file "unfixit.l" reverses the changes in "fixit.l", to restore long names.
This is useful when trying to build diff files as created here.
The file "initscan.mvs.c" is an already "flexed" version of scan.l, in an
EBCDIC environment.
To install in an MVS environment, use patch to apply the diffs to flex 2.3,
then run "fixit" on all .c, .h, .l, .y, and .skel files. Move the files
to the MVS machine, and compile each of the .c files. (You will need a
"yacc" functional equivalent under MVS to expand parse.y in that
environment.) Link together, and the resulting flex should be ready to
go. To test, run the MVSflex -is8 -Ce on the scan.l, and you should get
back a file which is identical to initscan.mvs.c.
Enjoy.

Notes on the THINK C version of Flex 2.4.6
Scott Hofmann 23-JUL-94
Internet: scotth@visix.com
The only changes needed to compile Flex 2.4.6 under Symantec C++ 6.0 was
to #include <console.h> in main.c and call ccommand() just before flexinit()
in main(). The notes below are mostly of historical significance only; most
of the workarounds below were to get around restrictions/problems in earlier
versions of THINK C. The only section which still applies is Russell Finn's
description of how to make Flex generate output of type 'KAHL'. Also, 4-byte
ints must be used by any project which uses Flex output.
If you want to recreate the project, you'll need to add the files
alloca.c and xmalloc.c in this directory. Both files are copylefted; see
the GNU General Public License for details. You will also need to recompile
both the ANSI and unix libraries to use 4 byte ints, and if you want the
files that flex creates to have 'KAHL' as the creator you'll need to apply
Russell Finn's patch.
Notes on the THINK C version of Flex 2.3.7
Jonas Barklund, 25-JAN-92
Internet: jonas@csd.uu.se
I have merged the sources for Flex version 2.3.7 with the older version
which was hacked for THINK C version 4. I have conditionalized the code
so that I think it should work with both THINK C version 4 and 5 (for
those of you who don't know: the THINK_C symbol is defined as 1 in version
4 and as 5 in version 5). I have put in some missing prototypes, so it
compiles also with "require prototypes" on.
Most of the notes below still apply, in particular that about the MakeRes
program.
Notes on the THINK C version of Flex
Russell S. Finn, 19-FEB-90
Internet: rsfinn@athena.mit.edu, rsfinn@neutron.lcs.mit.edu
CompuServe: 76377,1107
GEnie: RSFINN
Flex appears to be covered by a copyright notice from the University of
California, similar to the one covering Berkeley Unix; the Free Software
Foundation is not part of the picture here. So here is a version
created with THINK C 4.0, along with the source code; as with the
Bison distribution, I am including *all* of the source code I received
with the package.
The current version (modification date January 25, 1990) has only the
bare-bones interface provided by the THINK C library routine "ccommand",
which allows the user to type a command line and to redirect the output.
Perhaps someday I may try to implement a "real" user interface; perhaps
not.
The only modifications made to the source file are surrounded by "#ifdef
THINK_C"..."#endif"; in theory, then, these sources could be recompiled
on another system if necessary. These are the actual files modified:
alloca.c, dfa.c, flexdef.h, main.c, misc.c, scan.c, sym.c. Most of these
changes were minor, and many of them would have been unnecessary if the
original Flex source code had been written for an ANSI-compliant C compiler.
In addition, the file "macutils.c" is completely new; see the discussion
of "MakeRes" below.
THINK C users may find it convenient to have the output text files written
by Flex be THINK C documents. To do this, create a copy of the "ANSI"
project called "ANSI-KAHL", and a copy of the file "fopen.c" called
"fopen-KAHL.c". In the copy, find the routine "setfiletype", and replace
the lines:
if (!(oflag & F_BINARY))
pb.ioFlFndrInfo.fdType = 'TEXT';
with the lines:
if (!(oflag & F_BINARY)) {
pb.ioFlFndrInfo.fdType = 'TEXT';
pb.ioFlFndrInfo.fdCreator = 'KAHL';
}
Replace "fopen.c" with the new "fopen-KAHL.c", rebuild the new project
"ANSI-KAHL", and use this project in the project file "Flex.¹"
instead of the "ANSI" project.
** The "MakeRes" program
The output files created by Flex contain large amounts of preinitialized
static data; the file "scan.c" contained in the Flex.¹ project is one
such file. However, the Macintosh architecture limits normal applications
to 32K of global data. In many cases (including Flex), this limit can
be surpassed by the static data generated by Flex.
The solution I have implemented for the THINK C version of Flex is to
extract the data tables from the Flex output file, and paste them into
the file "MakeRes.c". Then, by recompiling and running the program in
the "MakeRes.¹" project (it is not necessary to create an application),
a resource file called "Flex.¹.rsrc" is created in the current directory.
The Flex output file "scan.c" has been modified to load the static data
from the resource fork of the Flex application. This is done by calling
the "load_table" function, which is defined in the file "macutils.c".
In the application for which I needed Flex, the data tables were small
enough that I didn't need to do this. However, if your application
requires you to do this, simply follow the model of "scan.c"; the MakeRes
project and source code has been included for your use.

/*
alloca -- (mostly) portable public-domain implementation -- D A Gwyn
last edit: 86/05/30 rms
include config.h, since on VMS it renames some symbols.
Use xmalloc instead of malloc.
This implementation of the PWB library alloca() function,
which is used to allocate space off the run-time stack so
that it is automatically reclaimed upon procedure exit,
was inspired by discussions with J. Q. Johnson of Cornell.
It should work under any C implementation that uses an
actual procedure stack (as opposed to a linked list of
frames). There are some preprocessor constants that can
be defined when compiling for your specific system, for
improved efficiency; however, the defaults should be okay.
The general concept of this implementation is to keep
track of all alloca()-allocated blocks, and reclaim any
that are found to be deeper in the stack than the current
invocation. This heuristic does not reclaim storage as
soon as it becomes invalid, but it will do so eventually.
As a special case, alloca(0) reclaims storage without
allocating any. It is a good idea to use alloca(0) in
your main control loop, etc. to force garbage collection.

Otherwise (that successor not yet having been published), ask me for a copy
of the item on RfSchtkt@maze.ruca.ua.ac.be. Bison's messages are not as
disciplined as flex' ones, so it should get more discipline first.
Specifically (in addition to what's described in the KBNS item):
makeUser.o and make_support.o should be added to OBJECTS in Makefile.in
In parse.y, line_pinpoint() (assumption all messages ultimately go there), add:
make_support(

// it seems
syntaxerror?0:1,
NULL,

Miscellaneous flex stuff. The items which have been tested with flex 2.5 are:
- texinfo/, a subdirectory containing a "texinfo" version of flex(1)
and the corresponding "info" files (contributed by Francois Pinard).
- VMS/, a subdirectory containing makefiles, configuration files,
run-time support, and installation notes for building flex 2.5
on VMS (contributed by Pat Rankin).
- Borland/ - makefile and config.h for Borland 4.02 compiler
(contributed by Terrence O Kane, who notes that no source
code changes were necessary).
- NT/ - Makefile and config.h for NT, contributed by Stan Adermann.
- OS2/ - Makefile and config.h for building flex under OS/2,
contributed by Kai Uwe Rommel.
- Amiga/: notes on building flex for the Amiga, contributed
by Andreas Scherer.
- parse.c, parse.h - output of running yacc (byacc, actually)
on parse.y. If your system doesn't have a flavor of yacc available,
copy these into the main flex source directory instead.
- flex.man - preformatted version of flex man page
The following have been tested using flex 2.4:
- debflex.awk, an awk script for anotating flex debug output.
It presently only works with gawk and mawk, not with "old"
or "new" awk.
- NeXT: ProjectBuilder.app support for use in the NeXT world.
- Notes on building flex for the Macintosh using Think-C,
in the Macintosh/ subdirectory.
- testxxLexer.l, a sample C++ program that uses flex's scanner
class option ("-+").
- fastwc/, a subdirectory containing examples of how to use flex
to write progressively higher-performance versions of the Unix
"wc" utility. This certainly should work with 2.5, but hasn't
been tested.
- Borland.old/: notes on building flex 2.4 for Borland C++ 3.1
on MS-DOS. These shouldn't be needed for flex 2.5. Included
only in case you encounter unanticipated difficulties.
- EBCDIC: contact information for building flex for EBCDIC.
The following are all out-of-date with respect to flex release 2.4 (and
in general up-to-date for flex 2.3):
- Atari/Atari.patches, patches for porting flex to the Atari and
to Minix.
- A number of notes and Makefiles for compiling flex under MS-DOS,
in the MSDOS/ subdirectory.
- Notes on building flex for MVS, in the MVS/ subdirectory.
If any of this is out-of-date and can be deleted, please let me know.
And the following is included for compatibility with some broken versions
of bison:
- alloca.c, a public-domain, mostly-portable version of the
alloca() routine (used by bison's parsers) written by D. A. Gwyn.
Many thanks to those who contributed these files. Updated versions will
be appreciated!

Brief instructions for building flex 2.5.x for VMS:
0) if you have either MMS (from Digital) or MMK (freeware) for use
as a `make' utility, follow the directions in steps #1 through #5 below.
If not, execute
@BUILD.COM xxxC
where "xxxC" is either "VAXC" or "DECC" or "GNUC", and then skip to
step #5.
1) set default to the source directory (not the [.MISC.VMS] subdirectory
where this file is located).
2) COPY [.MISC.VMS]DESCRIP.MMS []*.*
(Recursive invocations of `make' for the `bigcheck' test assume that the
makefile will be found as descrip.mms in the current directory.)
To build with VAX C for VAX/VMS:
3) MMS /MACRO=("VAXC=1") FLEX.EXE
(The /macro qualifier is optional in this case.)
To build with GNU C for VAX/VMS:
2.5) possibly edit descrip.mms to uncomment `SET COMMAND' for GCCINIT,
depending on local site configuration
3) MMS /MACRO=("GNUC=1") FLEX.EXE
To build with DEC C for either VAX/VMS or Alpha/VMS:
3) MMS /MACRO=("DECC=1") FLEX.EXE
(Expect one or two informational messages from the compiler about
implicitly declared functions.)
Minimal testing of the resulting program:
4) MMS CHECK
(If `diff' reports no warnings, the test has succeeded.)
More thorough testing:
4.5) MMS /MACRO=("xxxC=1") BIGCHECK ! "xxxC=1" as in step #3 above
(If using an older version of MMK rather than MMS, this might fail when
`make' is invoked recursively due to excessive BYTLM usage by MMK.)
Installation (the VMS makefile does not support an `install' target;
you'll need to do this part manually):
5) copy flex.exe, flex.doc, flex.skl, flexlib.olb, and FlexLexer.h to
location(s) appropriate for your site. To use flex, define a "foreign"
command by making a DCL symbol whose value begins with a dollar sign
immediately followed by the filename for flex.exe, as in
$ flex :== $local_tools:flex.exe
where `local_tools:' is the logical name pointing to flex.exe's location.
This symbol will ordinarily be a candidate for your login.com. When
invoking flex, upper- or mixed-case command line options must be enclosed
in quotes. For example,
$ flex "-Pxyz" "-L" -t mylexer.l > mylexer.c
(use prefix "xyz" instead of "yy", suppress `#line' compiler directives
in the output, write the output to `stdout', process file mylexer.l,
and capture `stdout' in file mylexer.c). As illustrated here, this VMS
version of flex supports emulation of command line I/O redirection used
by Unix shells.
flex.exe -- the executable image for the flex program;
flex.doc -- documentation, the "man page" describing flex (flex.1
processed with `nroff -man' followed by `col -b');
flex.skl -- a text file containing flex's default skeleton;
with this version of flex, it is for reference only;
flex.exe does not need to know where to find it;
flexlib.olb -- an object library containing some support routines;
you might need to link your generated lexer against
it, depending on how your program is designed;
flex.exe does not access it; it corresponds to
`libfl.a' under Unix;
FlexLexer.h -- header file used for C++ class-based lexers; not
needed for ordinary C lexers.
Notes:
This VMS port of flex supports only the original Unix command line
interface, not the native DCL interface which was available for flex 2.3.
build.com -- DCL command procedure as alternative to descrip.mms;
descrip.mms -- 2.5.x makefile for use with MMS or MMK (see step #1);
mkskel.tpu -- TPU program used to make skel.c from flex.skl for full
build from scratch; performs same function as mkskel.sh;
vms-conf.h -- pre-configured `conf.in', copied to [-.-]config.h;
vms-code.c -- VMS-specific support code, copied to [-.-]vms-code.c;
README.VMS -- this file

/* alloca.c -- allocate automatically reclaimed memory
(Mostly) portable public-domain implementation -- D A Gwyn
This implementation of the PWB library alloca function,
which is used to allocate space off the run-time stack so
that it is automatically reclaimed upon procedure exit,
was inspired by discussions with J. Q. Johnson of Cornell.
J.Otto Tennant <jot@cray.com> contributed the Cray support.
There are some preprocessor constants that can
be defined when compiling for your specific system, for
improved efficiency; however, the defaults should be okay.
The general concept of this implementation is to keep
track of all alloca-allocated blocks, and reclaim any
that are found to be deeper in the stack than the current
invocation. This heuristic does not reclaim storage as
soon as it becomes invalid, but it will do so eventually.
As a special case, alloca(0) reclaims storage without
allocating any. It is a good idea to use alloca(0) in
your main control loop, etc. to force garbage collection. */

This directory contains some examples illustrating techniques for extracting
high-performance from flex scanners. Each program implements a simplified
version of the Unix "wc" tool: read text from stdin and print the number of
characters, words, and lines present in the text. All programs were compiled
using gcc (version unavailable, sorry) with the -O flag, and run on a
SPARCstation 1+. The input used was a PostScript file, mainly containing
figures, with the following "wc" counts:
lines words characters
214217 635954 2592172
The basic principles illustrated by these programs are:
- match as much text with each rule as possible
- adding rules does not slow you down!
- avoid backing up
and the big caveat that comes with them is:
- you buy performance with decreased maintainability; make
sure you really need it before applying the above techniques.
See the "Performance Considerations" section of flexdoc for more
details regarding these principles.
The different versions of "wc":
mywc.c
a simple but fairly efficient C version
wc1.l a naive flex "wc" implementation
wc2.l somewhat faster; adds rules to match multiple tokens at once
wc3.l faster still; adds more rules to match longer runs of tokens
wc4.l fastest; still more rules added; hard to do much better
using flex (or, I suspect, hand-coding)
wc5.l identical to wc3.l except one rule has been slightly
shortened, introducing backing-up
Timing results (all times in user CPU seconds):
program time notes
------- ---- -----
wc1 16.4 default flex table compression (= -Cem)
wc1 6.7 -Cf compression option
/bin/wc 5.8 Sun's standard "wc" tool
mywc 4.6 simple but better C implementation!
wc2 4.6 as good as C implementation; built using -Cf
wc3 3.8 -Cf
wc4 3.3 -Cf
wc5 5.7 -Cf; ouch, backing up is expensive

This is release 2.5 of flex. See "version.h" for the exact patch-level.
See the file "NEWS" to find out what is new in this Flex release.
Read the file "INSTALL" for general installation directives. Peek near
the beginning of the file "Makefile.in" for special DEFS values. On most
systems, you can just run the "configure" script and type "make" to build
flex; then "make check" to test whether it built correctly; and if it did,
then "make install" to install it.
If you're feeling adventurous, you can also issue "make bigcheck" (be
prepared to wait a while).
Note that flex is distributed under a copyright very similar to that of
BSD Unix, and not under the GNU General Public License (GPL), except for
the "configure" script, which is covered by the GPL.
Many thanks to the 2.5 beta-testers for finding bugs and helping test and
increase portability: Stan Adermann, Scott David Daniels, Charles Elliott,
Joe Gayda, Chris Meier, James Nordby, Terrence O'Kane, Karsten Pahnke,
Francois Pinard, Pat Rankin, Andreas Scherer, Marc Wiese, Nathan Zelle.
Please send bug reports and feedback to: Vern Paxson (vern@ee.lbl.gov).
