ScriptForge.Session service
The Session service gathers various general-purpose methods about:
-
the installation or execution environment
-
UNO introspection
-
the invocation of external scripts or programs
Service invocation
Before using the Session service the ScriptForge library needs to be loaded or imported:
• Basic macros require to load ScriptForge library using the following statement:
GlobalScope.BasicLibraries.loadLibrary("ScriptForge")
• Python scripts require an import from scriptforge module:
from scriptforge import CreateScriptService
GlobalScope.BasicLibraries.LoadLibrary("ScriptForge")
Dim session As Variant
session = CreateScriptService("Session")
from scriptforge import CreateScriptService
session = CreateScriptService("Session")

List of Methods in the Session Service |
||
|---|---|---|
|
ExecuteBasicScript |
HasUnoProperty |
|
Execute... methods in Session service behave as follows:
Arguments are passed by value. Changes made by the called function to the arguments do not update their values in the calling script.
A single value or an array of values is returned to the calling script.
ExecuteBasicScript
Execute the BASIC script given its name and location, and fetch its result, if any.
If the script returns nothing, which is the case of procedures defined with Sub, the returned value is Empty.
session.ExecuteBasicScript(scope: str, script: str, args: any[0..*]): any
scope: String specifying where the script is stored. It can be either "document" (constant session.SCRIPTISEMBEDDED) or "application" (constant session.SCRIPTISAPPLICATION).
script: String specifying the script to be called in the format "library.module.method" as a case-sensitive string.
-
The library is loaded in memory if necessary.
-
The module must not be a class module.
-
The method may be a Sub or a Function.
args: The arguments to be passed to the called script.
Consider the following Basic function named DummyFunction that is stored in "My Macros" in the "Standard" library inside a module named "Module1".
The function simply takes in two integer values v1 and v2 and return the sum of all values starting in v1 and ending in v2.
Function DummyFunction(v1 as Integer, v2 as Integer) As Long
Dim result as Long, i as Integer
For i = v1 To v2
result = result + i
Next i
DummyFunction = result
End Function
The examples below show how to call DummyFunction from within Basic and Python scripts.
Dim session : session = CreateScriptService("Session")
Dim b_script as String, result as Long
b_script = "Standard.Module1.DummyFunction"
result = session.ExecuteBasicScript("application", b_script, 1, 10)
MsgBox result ' 55
session = CreateScriptService("Session")
bas = CreateScriptService("Basic")
b_script = 'Standard.Module1.DummyFunction'
result = session.ExecuteBasicScript('application', b_script, 1, 10)
bas.MsgBox(result) # 55
ExecuteCalcFunction
Execute a Calc function using its English name and based on the given arguments.
If the arguments are arrays, the function is executed as an array formula.
session.ExecuteCalcFunction(calcfunction: str, args: any[0..*]): any
calcfunction: The name of the Calc function to be called, in English.
args: The arguments to be passed to the called Calc function. Each argument must be either a string, a numeric value or an array of arrays combining those types.
session.ExecuteCalcFunction("AVERAGE", 1, 5, 3, 7) ' 4
session.ExecuteCalcFunction("ABS", Array(Array(-1, 2, 3), Array(4, -5, 6), Array(7, 8, -9)))(2)(2) ' 9
session.ExecuteCalcFunction("LN", -3)
' Generates an error.
session.ExecuteCalcFunction("AVERAGE", 1, 5, 3, 7) # 4
session.ExecuteCalcFunction("ABS", ((-1, 2, 3), (4, -5, 6), (7, 8, -9)))[2][2] # 9
session.ExecuteCalcFunction("LN", -3)
ExecutePythonScript
Execute the Python script given its location and name, fetch its result if any. Result can be a single value or an array of values.
If the script is not found, or if it returns nothing, the returned value is Empty.
session.ExecutePythonScript(scope: str, script: str, args: any[0..*]): any
scope: One of the applicable constants listed above. The default value is session.SCRIPTISSHARED.
script: Either "library/module.py$method" or "module.py$method" or "myExtension.oxt|myScript|module.py$method" as a case-sensitive string.
library: The folder path to the Python module.
myScript: The folder containing the Python module.
module.py: The Python module.
method: The Python function.
args: The arguments to be passed to the called script.
Consider the Python function odd_integers defined below that creates a list with odd integer values between v1 and v2. Suppose this function is stored in a file named my_macros.py in your user scripts folder.
def odd_integers(v1, v2):
odd_list = [v for v in range(v1, v2 + 1) if v % 2 != 0]
return odd_list
Read the help page Python Scripts Organization and Location to learn more about where Python scripts can be stored.
The following examples show how to call the function odd_integers from within Basic and Python scripts.
Dim script as String, session as Object
script = "my_macros.py$odd_integers"
session = CreateScriptService("Session")
Dim result as Variant
result = session.ExecutePythonScript(session.SCRIPTISPERSONAL, script, 1, 9)
MsgBox SF_String.Represent(result)
session = CreateScriptService("Session")
script = "my_macros.py$odd_integers"
result = session.ExecutePythonScript(session.SCRIPTISPERSONAL, script, 1, 9)
bas.MsgBox(repr(result))
