Embryo @VERSION@


  libc libm

WARNING: gcc compatibility!!!
There seems to be some bug (or disagreement) between embryo and gcc 3.2.x
where IEEE floating point format encoding does not "agree" with embryo's own
hand-made tests. embryo_cc may not work if you compile using gcc 3.2.x. gcc
3.3.x is known to work fine. we are not 100% sure whose fault this is yet, so
we won't be jumping up and down, but be warned - gcc 3.2.x does not agree
with embryo.

To view the API docs, run ./gendoc and view doc/html/index.html.

OK a lot of people ask this. What is Embryo?

Embryo is primarily a shared library that gives you an API to load and control
interpreted programs compiled into an abstract machine bytecode that it
understands.  This abstract (or virtual) machine is similar to a real machine
with a CPU, but it is emulated in software.  The architecture is simple and is
the same as the abstract machine (AMX) in the 
<a href=http://www.compuphase.com/pawn.htm>PAWN</a> language (formerly called
SMALL) as it is based on exactly the same code. Embryo has modified the code
for the AMX extensively and has made it smaller and more portable.  It is VERY
small.  The total size of the virtual machine code AND header files is less
than 2500 lines of code.  It includes the floating point library support by
default as well.  This makes it one of the smallest interpreters around, and
thus makes is very efficient to use in code.

Embryo also uses the PAWN compiler from the same code base. This code has
barely been touched and so suffers from lots of portability issues. It has
been partially fixed and now works on both big and little endian but the code
still need to be gone over and really cleaned up . It does work, but it's only
just working.  It has been called embryo_cc and compiled a subset of PAWN
binary outputs.  It does not support packed strings, variable alignment, or
debugging output.  It does not support many features of the full PAWN
compiler because the Embryo AMX does not support these either. You will find
the Embryo codebase to work much better on Linux (and BSD and MacOS X) and
other UNIX operating systems as it has been developed and tested on them. IT
is known to work on:
  gcc Linux   (x86-32)
  gcc Linux   (PPC)
  gcc MacOS X (PPC)

And will likely work on more combinations. IT currently has problems on 64bit
SPARC CPUs. Other 64bit systems are untested. It is the aim to fix the code
so it works on all commonly used architectures (32, 64bit, big and little
endian, alignment forgiving/unforgiving).  So far 64bit support is the major

For more documentation please see the Language guide here:

<a href=http://www.compuphase.com/pawn/pawn-lang.pdf>Pawn Language Booklet</a>
This documents the PAWN language and is 100% relevant for Embryo and the
syntax of files it can compile (.sma files).

Any help is appreciated in helping clean and port this code, so feel free to
send patches to the Enlightenment development lists.

The main aim of Embryo is to provide an easy to use library for running
compiled PAWN programs and giving them access to the calling program and
any API it exports to the PAWN script.  PAWN programs/scripts are completely
sand-boxed. They cannot access any system or function calls other than the
ones provided by the calling application to the Embryo API. This means a
PAWN script cannot open or write to, delete or load files. It is fairly
harmless and this also keeps Embryo small.

This is a work in progress, so please be patient if things don't work for you
- and patches and help in fixing it is very much appreciated.


(as root unless youa re installing in your users directories):
  make install

RPM: To build rpm packages:
  sudo rpm -ta @PACKAGE@-@VERSION@.tar.gz

You will find rpm packages in your system /usr/src/redhat/* dirs (note you may
not need to use sudo or root if you have your own ~/.rpmrc. see rpm documents
for more details)

DEB: To build deb packages:

  tar zvf @PACKAGE@-@VERSION@.tar.gz
  dpkg-buildpackage -us -uc -rfakeroot
  cd ..
  rm -rf @PACKAGE@-@VERSION@

You will find all the debian source, binary etc. packages put in the directory
where you first untarred the source tarball.
