Figured out the problem with using the list method for path
manipulation. My latest code is at:
http://git.exim.org/users/tlyons/exim.git
So far, the code can do the following:
1. If python script alone is specified, exim attempts to load it from
python system paths.
2. If full path to python script is specified, it splits the path and
adds it to the system paths, then attempts to load it.
3. Expansion can call a function (ignores args)
4. Expansion can handle a returned string response.
5. Expansion can detect a returned {int,long_int,float}, but not
really do anything with it.
The following test code:
def string_output():
# Just a simple string being returned
return "Just a simple string"
def whole_number_output():
# Just a simple number being returned
return 5
def decimal_number_output():
# A decimal number being returned
return 8.8382912
def negative_number_output():
return -800
Produces this output:
[exim-build@tlyons ~/projects/exim/src (master_volatile_python)]$
build-Linux-i386/exim -be '${python{negative_number_output}}'
Integer returned
[exim-build@tlyons ~/projects/exim/src (master_volatile_python)]$
build-Linux-i386/exim -be '${python{decimal_number_output}}'
Float returned
[exim-build@tlyons ~/projects/exim/src (master_volatile_python)]$
build-Linux-i386/exim -be '${python{whole_number_output}}'
Integer returned
[exim-build@tlyons ~/projects/exim/src (master_volatile_python)]$
build-Linux-i386/exim -be '${python{string_output}}'
Just a simple string
