Detailed Description

The bps extension is a namespace assembling general BPS properties and functions.

There is only one static bps object, you can not create new objects of this type.

The extension needs to be loaded before it can be used:

importExtension('bps');
with (bps) {
    logOpen();
    log('Script started');
    ...

Embedded scripts (getting called by BPS C++ code) such as report scripts for example have the bps extension allready loaded by default.

Function Documentation

◆ canEditInstallSettings()

Boolean bps::canEditInstallSettings ( )

Check if the the local installation settings are editable.

The settings are stored in the file settings.ini in the application data folder selected while installing BPS.

Returns: true = editable, false = not editable.

◆ dateToTimestampString()

String bps::dateToTimestampString ( Date aDate )

Format date object to a timestamp string.

Parameters

aDate The date/time value.

Returns: The date/time as string YYYYMMDDHHMMSS

◆ decryptPin()

Number bps::decryptPin	(	Number	aUserid,
		Number	aPin
	)

Decrypt a user PIN.

PIN's are stored in an encrypted manner within the t_users table.

Parameters

aUserid	The user id.
aPin	The encrypted PIN.

Returns: The decrypted PIN.

◆ directory()

String bps::directory ( String aName = "" )

Get a BPS application directory.

The path is first searched in the environment where aName is prefixed with "BPS_".

When the path was not found in the environment variables, it is searched in the file bps.conf which is in the directory where the executable was started from. The key aName is expected in section [Paths].

If the found path is relative (not starting with a drive or slash/backslash), it is assumed to be relative to the BPS installation directory (one above the exe's). The returned path is made absolute under this premise.

Example 1: Relative path in environment variable

aName	Logs
Environment variable BPS_LOGS=	mylogs
BPS installation directory	C:\Program Files\IBK BPS 2.0.0
Returned path	C:/Program Files/IBK BPS 2.0.0/mylogs

Example 2: Relative path in bps.conf

aName	Logs
Environment variable BPS_LOGS=	(not found)
bps.conf: [Paths] ... Logs=	logs
BPS installation directory	C:\Program Files\IBK BPS 2.0.0
Returned path	C:/Program Files/IBK BPS 2.0.0/logs

Parameters

[in] aName Logical path name, for example: Logs, Plugins or Scripts. Get the BPS installation directory if aName is empty.

Returns: The absolute path with forward slashes, or empty string if path unknown.

◆ dump()

String bps::dump	(	Mixed	aValue,
		Number	aMaxDepth = `100`
	)

Format any variable (except functions) for debug output.

The formatted text is in ECMAscrip syntax, so basically it could be used as script source.

Parameters

[in]	aValue	Any object, array or scalar variable to dump.
[in]	aMaxDepth	Maximum recursion depth. Use 1 to list top level scalars of a object or array only.

Returns: The formatted text.

◆ encryptPin()

Number bps::encryptPin	(	Number	aUserid,
		Number	aPin
	)

Encrypt a user PIN.

PIN's are stored in an encrypted manner within the t_users table.

Parameters

aUserid	The user id.
aPin	The unencrypted PIN.

Returns: The encrypted PIN.

◆ formatError()

String bps::formatError ( Error aError )

Format an Error for display.

In case aError is an instance of Error, the message text is returned with the stack traceback information appended in human readable format. If aError if not instance or Error, its string representation is returned.

Parameters

[in] aError An object, possibly an instance of Error.

Returns: The formatted error message.
try {

throw new Error('this failed');

}

catch (err) {

perror( bps.formatError(err) );

}

perror
void perror(...)
Print the expressions (applying toString() if necessary) to the console error output (stderr),...

bps::Error
@ Error
Some unspecified error happened.
Definition: bps.js:26

◆ formatNiceNumber()

String bps::formatNiceNumber ( Number aValue )

Format a large integer number for better human readability, for example 1234567 becomes 1'234'567.

Parameters

aValue The value to process

Returns: The formatted text.

◆ isElevated()

Boolean bps::isElevated ( )

Check if the current process is running with elevated or limited privilege.

Elevated: Either UAC is enabled and the process was elevated by the administrator, or UAC is disabled and the process was started by a user who is a member of the Administrators group.

Not elevated (limited): Either UAC is enabled and the process was started normally without the elevation, or UAC is disabled and the process was started by a standard user.

Returns: true = elevated, false = limited.

◆ lerror()

void bps::lerror ( ... )

Print to log error output.

Print the expressions (applying toString() if necessary) to the console error output (stderr), followed by a newline. Lines will be indented by logLevel * 2 spaces. In case a logFile was opened, the output is also appended to the logFile.

Multiple expressions will be separated by a blank.

◆ lfile()

void bps::lfile ( ... )

Print lo log file only.

Append the expressions (applying toString() if necessary) to the logFile, followed by a newline. Lines will be indented by logLevel * 2 spaces.

Multiple expressions will be separated by a blank.

◆ log()

void bps::log ( ... )

Print to log output.

Print the argument expressions (applying toString() if necessary) to the console standard output (stdout), followed by a newline. Lines will be indented by logLevel * 2 spaces. In case a logFile was opened, the output is also appended to the logFile.

Multiple expressions will be separated by a blank.

◆ logClose()

void bps::logClose ( )

Close the log file.

Writes the ending date/time and the elapsed time into the log file in case one is opened.

◆ logOpen()

void bps::logOpen ( )

Opens the log file and writes the script name and starting date/time into it.

The log directory is determined as:

If a bps.conf file is present in the applicationDirPath, the variables Prefix and Logs in the Paths section of the the file are recognized. The Prefix is only used if Logs is not an absolute path.

In this example the log files will be stored in D:/Projekte/BPS2/logs:
[Paths]

Prefix = D:/Projekte/BPS2

Logs = logs

In this example the log files will be stored in E:/bps/logfiles, the Prefix is ignored because Logs is an absolute path:
[Paths]

Prefix = D:/Projekte/BPS2

Logs = E:/bps/logfiles
In case no bps.conf file is present, or the Prefix or Logs settings are not found in the Paths section, Prefix will default to applicationDirPath and Logs will default to "logs".

Note: The log directory must allready exist before calling logOpen, otherwise no log file will be opened.

The filename of the log will be the same as the script name, but with the extension .log instead of .js

◆ msleep()

void bps::msleep ( Number aMilliseconds )

Sleep for the time specified in milliseconds.

No event processing will be done so the application will be unresponsive. Use mwait() in case to for non-blocking sleeping.

Parameters

aMilliseconds Number of milliseconds to sleep.

◆ mwait()

void bps::mwait ( Number aMilliseconds )

Wait for a number of milliseconds.

While waiting, events will be processed and the application will stay responsive to user interface events and network communication. If aMilliseconds is <= 0, the function returns immediately after processing any pending events.

Parameters

aMilliseconds The time to wait.

◆ personalFolder()

String bps::personalFolder ( )

Get the personal data folder.

Under windows this is the path of "My documents" or "Eigene Dateien". Under other operating systems this function is equivalent to QDir::homePath().

Returns: The personal data folder.

◆ round()

Number bps::round	(	Number	aValue,
		Number	aDigits = `3`
	)

Round off as per standard commercial practice.

Parameters

[in]	aValue	The value to round off.
[in]	aDigits	Number of digits behind the decimal point.

Returns: The rounded off value.

◆ sleep()

void bps::sleep ( Number aSeconds )

Sleep for the time specified in seconds.

No event processing will be done so the application will be unresponsive. Use wait() in case to for non-blocking sleeping.

Parameters

aSeconds Number of seconds to sleep.

◆ sprintf()

String bps::sprintf	(	String	aFormat,
		Mixed	aArgs
	)

A string formatting function.

The placeholders in the format string are marked by "%" and are followed by one or more of these elements, in this order:

An optional "+" sign that forces to preceed the result with a plus or minus sign on numeric values. By default, only the "-" sign is used on negative numbers.
An optional padding specifier that says what character to use for padding (if specified). Possible values are 0 or any other character precedeed by a single quote '. The default is to pad with spaces.
An optional "-" sign, that causes sprintf to left-align the result of this placeholder. The default is to right-align the result.
An optional number, that says how many characters the result should have. If the value to be returned is shorter than this number, the result will be padded.
An optional precision modifier, consisting of a "." (dot) followed by a number, that says how many digits should be displayed for floating point numbers. When used on a string, it causes the result to be truncated.
A type specifier that can be any of:

% - print a literal "%" character
b - print an integer as a binary number
c - print an integer as the character with that ASCII value
d - print an integer as a signed decimal number
e - print a float as scientific notation
u - print an integer as an unsigned decimal number
f - print a float as is
o - print an integer as an octal number
s - print a string as is
x - print an integer as a hexadecimal number (lower-case)
X - print an integer as a hexadecimal number (upper-case)

You can also swap the arguments. That is, the order of the placeholders doesn't have to match the order of the arguments. You can do that by simply indicating in the format string which arguments the placeholders refer to:

sprintf("The quick %4$s %3$s jumps over the lazy %1$s %2$s",

'Tail', 'Dogs', 'Fox', 'brown');

bps::sprintf

String sprintf(String aFormat, Mixed aArgs)

A string formatting function.

You can repeat the placeholders without having to increase the number of arguments.

Parameters

aFormat	The string that must be left padded.
aArgs	An arbitrary number of arguments.The

Returns: The formatted string.

◆ timestampStringToDate()

Returns: The parsed Date object, or null in case the text is invalid.

◆ usleep()

void bps::usleep ( Number aMicroseconds )

Sleep for the time specified in microseconds.

Parameters

aMicroseconds Number of microseconds to sleep.

◆ wait()

void bps::wait ( Number aSeconds )

Wait for a number of seconds.

While waiting, events will be processed and the application will stay responsive to user interface events and network communication. If aSeconds is <= 0, the function returns immediately after processing any pending events.

Parameters

aSeconds The time to wait.

Variable Documentation

◆ logFile
