# ScriptForge Method Signatures

ScriptForge libraries aggregate macro scripting resources for LibreOffice to be invoked from Basic macros or Python scripts. Its modules and classes are invoked from user scripts as "Services" that expose properties, methods and events.

- Whenever service methods are proposed solely for LibreOffice Basic, their syntax presentation matches that of Basic subroutines, functions or properties.

- Whenever service methods are proposed for Python and Basic, or solely for Python, their syntax and arguments use a specific textual layout.

## Basic only service method

Typographical characters such as brackets, ellipsis or curly braces denote optional, repetitive or compulsory arguments:

- [opt1|opt2|opt3] Items inside brackets are optional, alternatives are indicated with a vertical bar,

- case[[sep]…] An ellipsis indicates a possible repetition, an optional separator may be specified,

- {choice1|choice2} Items inside curly braces are mandatory, alternatives are indicated with a vertical bar.

### Example:

           FSO.HashFile(FileName As String, _
               Algorithm As String = {MD5|SHA1|SHA224|SHA256|SHA384|SHA512}) As String
           SF_Array.ImportFromCSVFile(FileName As String, _
               [Delimiter = ","], [DateFormat As String]) As Variant
           SF_String.SplitNotQuoted(InputStr As String, _
              [Delimiter As String], [Occurrences As Long], [QuoteChar As String]) As Variant

## Python or Basic service methods

The following typographical rules are mixing the UML notation, the API documentation layout and the UNO object inspector user interface:

- Optional parameters are indicated with either opt, '=' accompanying a default value, or '[ ]' brackets.

- arguments are lowercased, in order to comply with Python PEP 8 while Basic is case-agnostic.

- Collections arguments or API sequences are denoted using UML multiplicity. That applies also to return values.

- Basic data types and Python annotations are syntactically transposed as:

LibreOffice Basic | Syntax | Python
--- | --- | ---
Boolean | bool | bool
Date | datetime | datetime
Double | float | float
Integer | int | int
Long | int | int
Object | obj |
Single | float | float
String | str | str
Variant | any |
UNO Object | uno |
User Defined Type (UDT) | obj |
ScriptForge service | svc |

### Example:

svc.Forms( opt form: any ): svc[0..*]

svc.MsgBox( prompt: str, buttons = svc.MB_OK , opt title: str ): opt str

svc.InputBox( prompt: str, default = "", [ title: str ], [ xpostwips: int, ypostwips: int ] ): str
