Detailed Description

GnuCash Options System for Book, Report, and Stylesheet Options.

The GnuCash Options System supports two somewhat different purposes:

• File properties, such as business information and whether to use automatic trading accounts.
• Report options for configuring and customizing reports. Most report options are user-configurable through a report options dialog but some are used as a way of passing enumeration values between the scheme modules that generate the report.

The options system is centered on an options database or optiondb. A separate optionsdb is created and instantiated for every use, so the book gets one at the beginning of the session with its values loaded from KVP, and every report gets one when the report is run, as do report stylesheets when they are edited. Customized report and stylesheet options are saved as Scheme code fragments in files in the user's GnuCash Config directory.

Note

Persistence via text scheme code is a security vulnerability as it enables an attacker to make GnuCash execute arbitrary code. The Guile interpreter affords full system access with at least the user's privileges.

Typedef Documentation

GncItem

using GncItem = std::pair<QofIdTypeConst, GncGUID>

class GncOptionQofinstanceValue

QofInstances know what type they are but getting them to tell you is a pain so we put them in a pair with a type identifier.

Definition at line 164 of file gnc-option-impl.hpp.

Enumeration Type Documentation

RelativeDatePeriod

enum RelativeDatePeriod : int

strong

Reporting periods relative to the current date.

The original design allowed custom RelativeDatePeriods, but that facility is unused so we'll go with compiled-in enums.

Function Documentation

gnc_account_list_from_types()

GncOptionAccountList gnc_account_list_from_types	(	QofBook *	book,
		const GncOptionAccountTypeList &	types
	)

Extract a list of accounts in the book having one of the GNCAccountTypes in types.

Note that in Scheme it's important to use this function and not to create a list of accounts using gnc-get-descendants-sorted because the latter method produces a SWIGTYPE for the accounts that's incompatible with the SWIGTYPE used in this module.

Parameters

book	The book whose accounts to search
types	A std::vector of GNCAccountType containing the Account types to include in ther result

Returns

A std::vector<const Account*> of all accounts in the book having the Account types in the types parameter.

Definition at line 684 of file gnc-optiondb.cpp.

{
    GncOptionAccountList list;
    AccountPair funcdata{list, types};
    Account* base_acct = gnc_book_get_root_account(book);
    gnc_account_foreach_descendant(base_acct, (AccountCb)find_children,
                                   &funcdata);
    return list;
}

gnc_make_option()

template<typename ValueType >

GncOption* gnc_make_option	(	const char *	section,
		const char *	name,
		const char *	key,
		const char *	doc_string,
		ValueType	value,
		GncOptionUIType	ui_type
	)

Free function wrapping GncOption's constructor.

The type of GncOptionValue to create is determined from the UI type. Some GncOptionValue types require more parameters for their constructors and can't be created with this function.

Definition at line 256 of file gnc-option.hpp.

{
    return new GncOption(section, name, key, doc_string, value, ui_type);
}

gnc_option_db_book_options()

void gnc_option_db_book_options

(

GncOptionDB *

)

Register the standard option set for a QofBook.

Parameters

}

gnc_relative_date_to_time64()

time64 gnc_relative_date_to_time64

(

RelativeDatePeriod

)

Convert a RelativeDatePeriod value to a concrete time64 by applying the value to the current time.

For example if it is now 3:15:42 PM local time 3 June, calling this with a period RelativeDatePeriod::ONE_WEEK_AHEAD will return a time64 representing 3:15:42 PM local time 10 June of this year. Times for START periods are changed to midnight local time and for END periods to 23:59:59 local time so for example if the period is instead RelativeDatePeriod::START_THIS_MONTH the time64 will represent 00:00:00 1 June and if it is RelativeDatePeriod::END_THIS_MONTH the time64 will be for 23:59:59 30 June, both in the current time zone.

Parameters

period

The relative date period to use to calculate the concrete date.

Returns

a time64.
