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')
warning

ScriptForge.Basic service is limited to Python scripts.

CDate

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

note

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


Синтаксис:

svc.CDate(expression: any): obj

Параметри:

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 Tools - Options - 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.

Приклад:

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

Коди форматування

In BASIC, 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.

Ви можете встановити локаль для керування форматуванням чисел, дат і валют у LibreOffice Basic у Tools - Параметри - Мови та локалі - Загальні. У кодах формату Basic десяткова крапка (.) завжди використовується як заповнювач для десяткового роздільника, визначеного у вашій локалі, і буде замінена відповідним символом.

Те ж саме стосується і параметрів мови для форматів дати, часу і валюти. Код формату Basic буде інтерпретуватися і відображатися у відповідності з національними установками.

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

Code

Description

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.

. (period)

The decimal placeholder determines the number of decimal places to the left and right of the decimal separator.

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.

Використання крапки як розділювача груп розрядів чи десяткового розділювача визначається параметрами регіональних стандартів операційної системи. При введенні числа безпосередньо у програмний код Basic завжди використовуйте в ролі десяткового розділювача крапку. Фактичний вигляд десяткового розділювача визначається форматом чисел, який заданий у системних параметрах.

%

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.

Якщо експонента від'ємна, то знак мінус виводиться безпосередньо перед експонентою з E-, E+, e-, e+. Якщо ж експонента є додатною, то знак плюс виводиться лише перед експонентами з Е+ або е+.

- + $ ( ) space

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

\

Щоб показати інші символи, необхідно поставити перед ними обернену косу риску (\) або взяти їх у лапки (" ").

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.

Зворотна коса риска в коді формату для того, щоб елемент виводився як символ, ставиться перед: символами для форматування дати й часу (a, c, d, h, m, n, p, q, s, t, w, y, /, :), символами для числового форматування (#, 0, %, E, e, кома, крапка) і символами для форматування рядків (@, &, <, >, !).


Predefined formats

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.

Якщо використовуються наперед визначені формати, то їхні назви повинні бути укладені в лапки.
