Servicio ScriptForge.Session

El servicio Session reúne varios métodos de uso general relativos a:

Invocación del servicio

Antes de utilizar el servicio Session, es necesario cargar o importar la biblioteca ScriptForge:

note

• Para cargar la biblioteca ScriptForge que necesitan las macros de Basic se debe usar la siguiente declaración:
GlobalScope.BasicLibraries.loadLibrary("ScriptForge")

• Los scripts de Python necesitan importar el módulo scriptforge:
from scriptforge import CreateScriptService


En BASIC

    GlobalScope.BasicLibraries.LoadLibrary("ScriptForge")
    Dim session As Variant
    session = CreateScriptService("Session")
  
En Python

    from scriptforge import CreateScriptService
    session = CreateScriptService("Session")

tip

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.

Sintaxis:

session.ExecuteBasicScript(scope: str, script: str, args: any[0..*]): any

Parámetros:

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.

args: The arguments to be passed to the called script.

Ejemplo:

Consider the following Basic function named DummyFunction that is stored in "My Macros" in the "Standard" library inside a module named "Module1".

La función simplemente recibe dos valores enteros, v1 y v2, y devuelve la suma de todos los valores a partir de v1 y que terminan en 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.

En BASIC

    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
  
En Python

    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.

Sintaxis:

session.ExecuteCalcFunction(calcfunction: str, args: any[0..*]): any

Parámetros:

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.

Ejemplo:

En BASIC

    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)
    ' Genera un error.
  
En Python

    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.

Si la secuencia de órdenes no se encuentra o no devuelve nada, el valor devuelto será Empty.

El marco de programación de macros de la API (interfaz de programación de aplicaciones) de LibreOffice admite la ejecución de secuencias de comandos entre Python y Basic u otros lenguajes de programación admitidos. Los argumentos se pueden pasar de un lado a otro entre llamadas, siempre que representen tipos de datos primitivos que ambos lenguajes reconozcan y suponiendo que el marco de programación de macros los convierta de forma adecuada.

Sintaxis:

session.ExecutePythonScript(scope: str, script: str, args: any[0..*]): any

Parámetros:

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.

args: The arguments to be passed to the called script.

Ejemplo:

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
  
tip

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.

En BASIC

    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)
  
En Python

    session = CreateScriptService("Session")
    script = "my_macros.py$odd_integers"
    result = session.ExecutePythonScript(session.SCRIPTISPERSONAL, script, 1, 9)
    bas.MsgBox(repr(result))
  

GetPDFExportOptions

Devuelve la configuración actual de exportación a PDF que se ha definido en el cuadro de diálogo Opciones de PDF, al cual se puede acceder al elegir Archivo ▸ Exportar a ▸ Exportar a PDF.

Export options set with the PDF Options dialog are kept for future use. Hence GetPDFExportOptions returns the settings currently defined. In addition, use SetPDFExportOptions to change current PDF export options.

This method returns a Dictionary object wherein each key represent export options and the corresponding values are the current PDF export settings.

tip

Read the PDF Export wiki page to learn more about all available options.


Sintaxis:

session.GetPDFExportOptions(): obj

Ejemplo:

En BASIC

    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
    ' ...
  
note

Este método está disponible únicamente para secuencias BASIC.
