I am now convinced that the global definitions I proposed earlier have

I attached a complete (but rather terse) description of syntax and semantics
that follows the mentioned sketch. Nested scopes are allowed, but (to keep
things simple) not inside file blocks. I am not wedded to this or any other
concrete detail; consider it as a request for comments.

I think we can move discussion to [email protected] from here on, so
please direct your replies there (unless you think it is of interest to a
wider audience).

Hi,

I would just like to mention that the discussion about msi here and with
Benjamin brought about the idea to implement msi in python.

Pymsi implements substitution files as python statements. By this

substitution

files may contain any python code aside from the usual "file" statements.

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-1.01.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

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
