Lianja Python Parameters

[Schlingmeier]

With execPython("file.py") I can execute the Python file, which works so far. My question is, can I also access variables created outside of Python? Is it also possible to access the table data set that is currently in focus without having to execute another database command in Python?
Thanks and greetings Olaf

You can call Python functions with arguments from LianjaScript.

See
https://www.lianja.com/doc/index.php/EXECPYTHON()

Inside your Python code you can call LianjaScript using:

Lianja.evaluate( cExpr )

and

Lianja.execute( cCommand )

You can therefore reference cursors and columns in the active record e.g.

value = Lianja.evaluate(“employees.lastname”)

In 9.3 the arguments are split into sys.argv[] when the execPython() call is made. This simplifies the LianjaScript/Python integration.

#File: barrytest.py
import Lianja
import sys


def myfunc(theArg):
    Lianja.writeOutput("myfunc was called with " + theArg)
    return Lianja.evaluate("now()")


returnvalue = myfunc( sys.argv[1] )

// call python code from LianjaScropt returning a result
result = execPython("barrytest.py", "arg1", "arg2", "arg3")
? result

execPython("file.py") is not returning returnvalue from the python file to the calling program. On executing the sample code in this thread (barrytest.py) I get the following output:

myfunc was called with arg1
.F.

There was an issue with the return value. I have fixed this in 9.4.7.
