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: GlobalScope.BasicLibraries.LoadLibrary("ScriptForge") Dim session As Variant session = CreateScriptService("Session") from scriptforge import CreateScriptService session = CreateScriptService("Session")

Constants

Below is a list of constants available to ease the designation of the library containing a Basic or Python script to invoke. Use them as session.CONSTANT.
CONSTANT Value Where to find the library? Applicable SCRIPTISEMBEDDED "document" in the document Basic + Python SCRIPTISAPPLICATION "application" in any shared library Basic SCRIPTISPERSONAL "user" in My Macros Python SCRIPTISPERSOXT "user:uno_packages" in an extension installed for the current user Python SCRIPTISSHARED "share" in %PRODUCTNAME macros Python SCRIPTISSHAROXT "share:uno_packages" in an extension installed for all users Python SCRIPTISOXT "uno_packages" in an extension but the installation parameters are unknown Python

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 ------------------------------------------------------------------------------------- Session service;ExecuteBasicScript

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 ------------------------------------------------------------------------------------ Session service;ExecuteCalcFunction

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 ------------------------------------------------------------------------------------ Session service;ExecutePythonScript

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))
GetPDFExportOptions ------------------------------------------------------------------------------------ Session service;GetPDFExportOptions

GetPDFExportOptions

This method returns a Dictionary object wherein each key represent export options and the corresponding values are the current PDF export settings. Read the PDF Export wiki page to learn more about all available options. session.GetPDFExportOptions(): obj Dim expSettings As Object, msg As String, key As String, optLabels As Variant expSettings = session.GetPDFExportOptions() optLabels = expSettings.Keys For Each key in optLabels msg = msg + key & ": " & expSettings.Item(key) & Chr(10) Next key MsgBox msg ' Zoom: 100 ' Changes: 4 ' Quality: 90 ' ...

Read the PDF Export wiki page to learn more about all available options. session.SetPDFExportOptions(pdfoptions: obj): bool pdfoptions: Dictionary object that defines the PDF export settings to be changed. Each key-value pair represents an export option and the value that will be set in the dialog. The following example changes the maximum image resolution to 150 dpi and exports the current document as a PDF file. Dim newSettings As Object, oDoc As Object Set oDoc = CreateScriptService("Document") Set newSettings = CreateScriptService("Dictionary") newSettings.Add("ReduceImageResolution", True) newSettings.Add("MaxImageResolution", 150) session.SetPDFExportOptions(newSettings) oDoc.ExportAsPDF("C:\Documents\myFile.pdf", Overwrite := True)
