ScriptForge.Basic service

The ScriptForge.Basic service proposes a collection of LibreOffice Basic methods to be executed in a Python context. Basic service methods reproduce the exact syntax and behaviour of Basic builtin functions.

Typical example:


   bas.MsgBox('Display this text in a message box from a Python script')

ScriptForge.Basic service is limited to Python scripts.

Вызов службы

Before using the Basic service, import the CreateScriptService() method from the scriptforge module:

CDate

Converts a numeric expression or a string to a datetime.datetime Python native object.

This method exposes the Basic builtin function CDate to Python scripts.

Синтаксис:

svc.CDate(expression: any): obj

Параметры:

expression: a numeric expression or a string representing a date.

When you convert a string expression, the date and time must be entered either in one of the date acceptance patterns defined for your locale setting (see - Languages and Locales - General) or in ISO date format (momentarily, only the ISO format with hyphens, e.g. "2012-12-31" is accepted). In numeric expressions, values to the left of the decimal represent the date, beginning from December 31, 1899. Values to the right of the decimal represent the time.

Пример:


    d = bas.CDate(1000.25)
    bas.MsgBox(str(d)) # 1902-09-26 06:00:00
    bas.MsgBox(d.year) # 1902

Синтаксис:

svc.Format(expression: any, format = ''): str

Параметры:

expression: Numeric expression that you want to convert to a formatted string.

format: String that specifies the format code for the number. If format is omitted, the Format function works like the LibreOffice Basic Str() function.

Return value:

Text string.

Formatting Codes

The following list describes the codes that you can use for formatting a numeric expression:

0: If expression has a digit at the position of the 0 in the format code, the digit is displayed, otherwise a zero is displayed.

If expression has fewer digits than the number of zeros in the format code, (on either side of the decimal), leading or trailing zeros are displayed. If the expression has more digits to the left of the decimal separator than the amount of zeros in the format code, the additional digits are displayed without formatting.

Decimal places in the expression are rounded according to the number of zeros that appear after the decimal separator in the format code.

#: If expression contains a digit at the position of the # placeholder in the format code, the digit is displayed, otherwise nothing is displayed at this position.

This symbol works like the 0, except that leading or trailing zeroes are not displayed if there are more # characters in the format code than digits in the expression. Only the relevant digits of the expression are displayed.

.:Десятичный заполнитель определяет количество десятичных разрядов слева и справа от десятичного разделителя.

If the format code contains only # placeholders to the left of this symbol, numbers less than 1 begin with a decimal separator. To always display a leading zero with fractional numbers, use 0 as a placeholder for the first digit to the left of the decimal separator.

%: Multiplies the expressionby 100 and inserts the percent sign (%) where the expression appears in the format code.

E- E+ e- e+ : If the format code contains at least one digit placeholder (0 or #) to the right of the symbol E-, E+, e-, or e+, the expression is formatted in the scientific or exponential format. The letter E or e is inserted between the number and the exponent. The number of placeholders for digits to the right of the symbol determines the number of digits in the exponent.

Если экспонента является отрицательной, знак минус отображается непосредственно перед экспонентой с E-, E+, e-, e+. Если экспонента является положительной, знак плюс отображается только перед экспонентами с Е+ или е+.

The thousands delimiter is displayed if the format code contains the delimiter enclosed by digit placeholders (0 or #).

Использование точки как разделителя групп разрядов или десятичного разделителя определяется параметрами региональных стандартов операционной системы. При вводе числа непосредственно в исходный код Basic всегда используйте в качестве десятичного разделителя точку. Фактически отображаемый в качестве десятичного разделителя символ определяется форматом чисел, заданным в системных параметрах.

- + $ ( ) space: A plus (+), minus (-), dollar ($), space, or brackets entered directly in the format code is displayed as a literal character.

Чтобы показать другие символы, необходимо предварить их обратной косой чертой (\) или заключить в кавычки (" ").

\ : The backslash displays the next character in the format code.

Characters in the format code that have a special meaning can only be displayed as literal characters if they are preceded by a backslash. The backslash itself is not displayed, unless you enter a double backslash (\\) in the format code.

Элементы, которые должны предваряться обратной косой чертой в коде формата для того, чтобы они отображались как символы, - это символы для форматирования даты и времени (a, c, d, h, m, n, p, q, s, t, w, y, /, :), символы для числового форматирования (#, 0, %, E, e, запятая, точка) и символы для форматирования строк (@, &, <, >, !).

You can also use the following predefined number formats. Except for "General Number", all of the predefined format codes return the number as a decimal number with two decimal places.

Если используются предопределённые форматы, их имена должны быть заключены в кавычки.

Predefined Formats

General Number. Числа отображаются так, как они введены.

Currency. Знак рубля помещается за числом, отрицательные числа заключаются в скобки.

Fixed. По крайней мере один разряд показывается перед десятичным разделителем.

Standard. Числа отображаются с разделителем групп разрядов.

Percent:. Число умножается на 100, и к этому числу добавляется знак процента.

Scientific. Числа отображаются в научном формате (например, 1,00E+03 для числа 1000).

A format code can be divided into three sections that are separated by semicolons. The first part defines the format for positive values, the second part for negative values, and the third part for zero. If you only specify one format code, it applies to all numbers.

You can set the locale used for controlling the formatting numbers, dates and currencies in LibreOffice Basic in - Languages and Locales - General. In Basic format codes, the decimal point (.) is always used as placeholder for the decimal separator defined in your locale and will be replaced by the corresponding character.

То же самое относится и к параметрам языка для форматов даты, времени и валюты. Код формата Basic будет интерпретироваться и отображаться в соответствии с определённым пользователем языком.

Пример:


    txt = bas.Format(6328.2, '##.##0.00')
    print(txt)
