Subject:	pymsi - a python alternative to msi

Hello EPICS community,

I would like to announce pymsi, a python package that
can replace the msi tool.

Here is a link to the documentation:
http://www-csr.bessy.de/control/pymsi/pymsi.html

Here is the download link:
http://www-csr.bessy.de/control/pymsi/dist/pymsi-1.0.tar.gz

And here is the command to clone our repository:
hg clone http://www-csr.bessy.de/control/pymsi/pymsi-hg pymsi

This is the main project page:
http://www-csr.bessy.de/control/pymsi

Pymsi is a python package that introduces a new substitution file format that
is similar to the old msi substitution format, but has valid python expressions
in it. Here is a short example:

do(
    file("adimovhgbl.template",
         subst(
           DESCVAR="adimovhgbl_ins.mac",
           GBASE="U3IV:",
           DRV="V",
           AdiMopVer="9",
           TRIG1="U3IV:AdiVGblPvr.PROC",
           TRIG2="U3IV:AdiVGblMvr.PROC",
         ),
         subst(
           DESCVAR="adimovhgbl_ins.mac",
           GBASE="U3IV:",
           DRV="H",
           AdiMopVer="9",
           TRIG1="U3IV:AdiHGblPvr.PROC",
           TRIG2="U3IV:AdiHGblMvr.PROC",
         ),
         pattern(
           ("GBASE","DRV","AdiMopVer","TRIG1","TRIG2"),
           ("U3IV","C","9","U3IV:AdiCGblPvr.PROC", "U3IV:AdiCGblMvr.PROC"),
           ("U3IV","P","9","U3IV:AdiPGblPvr.PROC", "U3IV:AdiPGblMvr.PROC"),
         ),
    ),
    file("adimogbl.template",
         subst(
           DESCVAR="adimogbl_ins.mac",
           GBASE="U3IV:",
           TRIG1="U3IV:AdiMoVGblTrg.PROC",
           TRIG2="U3IV:AdiMoHGblTrg.PROC",
           TRIG3="",
           TRIG4="",
         ),
    ),

)

Features of the package are:

* uses the EPICS maclib, so macro substitution is compatible with msi.
* substitution files are parseble by python, so all the features and powers of
the python scripting language are available.
* Scopes of macro definitions are well defined.
* The pymsi language (the format of the substitution files) can easily be
extended.
* conversion tool for conversion from old substitution file format included.
* Free to use for non-commercial applications

Greetings

Goetz Pfeiffer
