On behalf of the original OS/2 implementor Peter Miller
([email protected]) I'm pleased to announce the availabilitry of
MetaPost 0.62 for OS/2.

From John D. Hobby's original announcement of the public release of
MetaPost: "The MetaPost language is based on METAFONT, but it outputs
PostScript and it has the facilities for including TeX output and
manipulating the resuling picture."

Peter announced his implementation on the emtex-discussion list on Jan 9, 1995:

   "I compiled it for OS/2 using Eberhard Mattes' emx+gcc 0.9a (patch level
   2), nearly straight out of the box. I don't know yet how good the port is
   because I haven't really tested it that much (...). The examples and the
   manual run fine, but I didn't run the trip tests yet. It probably only
   runs on an HPFS drive (an 'mp.pool' file gets created in the process).
   BTW, this demonstrates what a great tool emx+gcc is for porting Unix
   applications to OS/2.
   (...)
   In any event, it sounds like a robust port to OS/2 (certainly HPFS) may
   not be that difficult. (...) I'd be willing to share anything I have
   (patch files or executables) with anyone interested, but who knows what
   I've missed with such a few changes to the Unix code."

When I contacted him early march it passed the trip-test. Since then I
installed and tested his implementation. When I asked him to make a package
ready for distribution on CTAN he suggested that I should do this.
So here it is.


Files
=====

The package consists of:

 1. mp_exe.zip   -   mp.exe
 2. config.mp    -   text file containing Peter's metapost setup for CONFIG.SYS
 3. mp_lib1.zip  -   containing the contents of the mp/bin library:
                     mp/bin/dmp.exe
                     mp/bin/dvitomp.exe
                     mp/bin/makempx (sh script for MS-Shell 2.3)
                     mp/bin/mptotex.exe
                     mp/bin/mptotr.exe
                     mp/bin/newer.exe
                     mp/bin/troffmpx (there was an error in this one)
 4. mp_lib2.zip  -   containing the remaining contents of the mp/ library:

                     mp/trchars.adj
                     mp/trfonts.map
                     mp/troffnum.mp
 5. mp_test.zip  -   contains a little test file to test the installation.

MP uses an Unix shell-script during runtime, so you have to install

 6. mh_sh23.zip  -   DataLogic Shell Version 2.3

If you do not have at least emtex beta12 you also have to install the latest
emx-runtime

 7. emxrt.zip    -   emx runtime package

To compile the original sources, which can be found on CTAN at
tex-archive/graphics/metapost, you need

 8. tftopl.zip   -   containing tftopl.exe
 9. pltotf.zip   -   containing pltotf.exe
10. tangle.zip   -   containing tangle.exe
11. web2c.zip    -   containing web2c.exe

                     sources
                     patches.pem
                     README.pem



Installation
============

The installation procedure describes the OS/2 installation. For a DOS
installation the DOS-part is at the end of this description.

For unpacking of the zip-files you should use a port of Info-ZIP's unzip. If
you have to use pkunzip use pkunzip 2.04g or later and use the -d option to
restore the subdirectory structure.

   1. Install emxrt.zip (emx 0.9a FIX 02 or later) if you do not have emtex
      beta12 or later. For OS/2 it should be sufficient to put the dll-files
      into a directory thats in your LIBPATH.

   2. Install MH_SH23B.ZIP. This archive contains several executables
      (16- and 32-bit versions for DOS and OS/2). Read the accompaning
      installation instructions in the INSTALL-file. I suggest using
      shemx.exe and renaming it to sh.exe

      Peter Miller used a minimum installation, which is:
      a.  Install 'profile.sh' in your HOME directory, which is
          defined in your CONFIG.SYS.  Remove all lines from it
          except for:

           #!sh
           BETA=V205Beta
           DATE=`date '+%.2y%.2m%.2d'`
           export MAILBOX EXINIT TERMCAP TERM LOGNAME MAIL ...
           export MAILCHECK MAILBOX LINK TIMEIN TIMEOUT BETA

      b.  Install 'profile.etc' as 'x:/etc/profile.sh', where 'x' is
          your boot drive.  Delete all lines except:

           #!sh
           HISTFILE=e:/etc/history.sh
           export EXINIT PATH TERM TZ HISTFILE

      c.  Install 'extend.lst' in your HOME directory, and put the
          following in your CONFIG.SYS

           SET EXTENDED_LINE=${HOME}/extend.lst

      d.  Install 'sh.ini' in the same directory you put sh.exe, and
          change its 'RootDrive' line to indicate the boot drive.  My
          boot drive is E:, so I set RootDrive to 5.

   3. Modify your CONFIG.SYS according to the supplied CONFIG.MP and set the
      environment for emTeX and MetaPost. Note that this is valid for the
      betatest EmTeX configuration prior to March 20, 1995!

   4. Reboot to make the changes valid.

   5. Install MetaPost.
      a.   Unpack MP.ZIP and put mp.exe in a directory that's in your path.
      b.   Create a directory e:\usr and use unzip to unpack MP_LIB1.ZIP
           and MP_LIB2.ZIP.
           This will produce three directories:

               e:\usr\lib\mp
               e:\usr\lib\mp\bin
               e:\usr\lib\mp\charlib

   6. If you would like to use another directory structure you have to
      modify your CONFIG.SYS and the file MAKEMPX (lines 1-7).


   7. Here's my installation:

      I have installed the MetaPost-library in e:/lib and modified MAKEMPX as
      follows:

           #!/unix/sh

           # PATH is used for echo, cat, rm, mv, as well as tex, latex
           # MPLIB is where newer, mptotex, and dvitomp are installed
           PATH=e:/unix\;d:/emtex/bin
           MPLIB=e:/lib/mp/bin
           DOTEX=${TEX:-tex386}


      This is the relevant portion of my CONFIG.SYS:

           SET MPINPUTS=.;e:/lib/mp
           SET MFINPUTS=D:/EMTEX/MFINPUTS/BASE
           SET TEXFONTS=D:/EMTEX/TEXTFMS1;D:/EMTEX/TEXTFMS2;E:/EMTEX/PSTFMS.OLD;D:/EMTEX/PSTFMS;
           SET MPXCOMMAND=sh /lib/mp/bin/makempx
           SET TEX=tex386.exe
           SET MPMEMS=.;/lib/mp
           SET MPPOOL=.;/lib/mp
           SET MPEDITOR=t
           SET TEXVFONTS=e:/emtex/vf.old

      (I have installed LaTeX2e with PSNFSS2e using the new naming scheme
      for postscript fonts, whereas MetaPost uses the "old" scheme that is
      supplied with dvips, e.g. "rawfonts". I haven't solved this problem
      until now.)



Recompiling
===========

MetaPost comes in WEB sources. To recompile you need an ANSI C compiler,
e.g. emx 0.9a, and WEB2c. Peter supplied the needed executables of TANGLE.EXE,
WEB2C.EXE, TFTOPL.EXE and PLTOTF.EXE. The needed patches are in PATCH.ZIP.

Peter writes:
   "I used the web2c files and the bootstrap version of tangle from the
   web2c distribution at labrea.stanford.edu. The only changes I made (as
   I recall) to the supplied C code were to change the path separator (for
   which there already was an #ifdef MS_DOS test), and to fix an error in
   the 'makempx' script. The scripts need a shell (e.g., sh.exe) and some
   shell utilities. I did make a few more changes to the makefiles. A robust
   port should be probably translate the scripts to .cmd files and make it
   work with FAT file systems."



Installation with DOS
=====================

Using this port of MetaPost with DOS should be no problem at all. There are
DOS executables of the shell in MH_SH23B.ZIP. You have to install emx0.9a
(FIX02 or later): all you need are EMX.EXE and EMU387 (if you don't have a
fpu). Install them according to the installation instructions which can be
found in EMXRT.ZIP.
Make a copy of MP.POO from MP.POOL and set the -t option of emx. We both did
not try using any 'btex...etex' constructs in DOS, however, because we don't
have TeX set up in DOS.



Testing the installation
========================

Unpack MP_TEST.ZIP with unzip. At the command prompt:

    mp examples <return>
        latex mpintro <return>
        bibtex mpintro <return>
        latex mpintro <return>
    latex mpintro <return>
    dvips mpintro <return>     % dvips
    gs mpintro <return>        % ghostscript



Happy MetaPosting,
