Detailed Description

A commodity is something of value that is easily tradeable or sellable; for example, currencies, stocks, bonds, grain, copper, and oil are all commodities.

This file provides an API for defining a commodities, and for working with collections of commodities. All GnuCash financial transactions must identify the commodity that is being traded.

Warning
The system used here does not follow the object handling and identification system (GncGUID's, Entities, etc.) that the other parts of GnuCash use. The API really should be ported over. This would allow us to get rid of the commodity table routines defined below.

Macro Definition Documentation

◆ gnc_commodity_get_kvp_frame

#define gnc_commodity_get_kvp_frame (   cm)    qof_instance_get_slots(QOF_INSTANCE(cm))

Get the internal KVP from of the currency.

You should rather use the individual accessors for individual properties

Definition at line 987 of file gnc-commodity.h.

◆ GNC_COMMODITY_NS_LEGACY

#define GNC_COMMODITY_NS_LEGACY   "GNC_LEGACY_CURRENCIES"

The commodity namespace definitions are used to tag a commodity by its type, or a stocks by the exchange where it is traded.

The LEGACY name is only used by the file i/o routines, and is converted to another commodity namespace before it is seen by the rest of the system. The ISO namespace represents currencies. With the exception of the NASDAQ namespace (which is used once in the binary importer) the rest of the namespace declarations are only used to populate an option menu in the commodity selection window.

Definition at line 103 of file gnc-commodity.h.

Enumeration Type Documentation

◆ QuoteSourceType

The quote source type enum account types are used to determine how the transaction data in the account is displayed.

These values can be safely changed from one release to the next.

Enumerator
SOURCE_SINGLE 

This quote source pulls from a single specific web site.

For example, the yahoo_australia source only pulls from the yahoo web site.

SOURCE_MULTI 

This quote source may pull from multiple web sites.

For example, the australia source may pull from ASX, yahoo, etc.

SOURCE_UNKNOWN 

This is a locally installed quote source that gnucash knows nothing about.

May pull from single or multiple locations.

SOURCE_CURRENCY 

The special currency quote source.

Definition at line 128 of file gnc-commodity.h.

129 {
130  SOURCE_SINGLE = 0,
134  SOURCE_MULTI,
141  SOURCE_MAX,

Function Documentation

◆ gnc_commodity_compare()

int gnc_commodity_compare ( const gnc_commodity *  a,
const gnc_commodity *  b 
)

This routine returns 0 if the two commodities are equal, 1 otherwise.

Commodities are equal if they have the same namespace, mnemonic, fullname, exchange private code and fraction. This function is useful for list-traversal comparison purposes where The semantics are 0, <0, or >0 (equal, greater than, less than) rather than "true or false"

Definition at line 1507 of file gnc-commodity.cpp.

1508 {
1509  if (a == b) return 0;
1510  if (a && !b) return 1;
1511  if (b && !a) return -1;
1512  return qof_instance_guid_compare(a, b);
1513 }
gint qof_instance_guid_compare(gconstpointer ptr1, gconstpointer ptr2)
Compare the GncGUID values of two instances.

◆ gnc_commodity_decrement_usage_count()

void gnc_commodity_decrement_usage_count ( gnc_commodity *  cm)

Decrement a commodity's internal counter that tracks how many accounts are using that commodity.

For currencies, this may have the side effect of disabling the commodity's quote flag.

Parameters
cmA pointer to a commodity data structure.

Definition at line 1440 of file gnc-commodity.cpp.

1470  LEAVE("(usage_count=%d)", priv->usage_count);
1471 }
void gnc_commodity_set_quote_flag(gnc_commodity *cm, const gboolean flag)
Set the automatic price quote flag for the specified commodity.
#define ENTER(format, args...)
Print a function entry debugging message.
Definition: qoflog.h:272
#define PWARN(format, args...)
Log a warning.
Definition: qoflog.h:250
#define LEAVE(format, args...)
Print a function exit debugging message.
Definition: qoflog.h:282
gboolean gnc_commodity_is_iso(const gnc_commodity *cm)
Checks to see if the specified commodity is an ISO 4217 recognized currency.

◆ gnc_commodity_destroy()

void gnc_commodity_destroy ( gnc_commodity *  cm)

Destroy a commodity.

Release all memory attached to this data structure.

Note
This function does not (can not) check to see if the commodity is referenced anywhere.
Parameters
cmThe commodity to destroy.

Definition at line 871 of file gnc-commodity.cpp.

◆ gnc_commodity_equal()

gboolean gnc_commodity_equal ( const gnc_commodity *  a,
const gnc_commodity *  b 
)

This routine returns TRUE if the two commodities are equal.

Commodities are equal if they have the same namespace, mnemonic, fullname, exchange private code and fraction.

Definition at line 1500 of file gnc-commodity.cpp.

1501 {
1502  return gnc_commodity_compare(a, b) == 0;
1503 }
int gnc_commodity_compare(const gnc_commodity *a, const gnc_commodity *b)
This routine returns 0 if the two commodities are equal, 1 otherwise.

◆ gnc_commodity_equiv()

gboolean gnc_commodity_equiv ( const gnc_commodity *  a,
const gnc_commodity *  b

This routine returns TRUE if the two commodities are equivalent.

Commodities are equivalent if they have the same namespace and mnemonic. Equivalent commodities may belong to different exchanges, may have different fullnames, and may have different fractions.

Definition at line 1483 of file gnc-commodity.cpp.

1484 {
1485  gnc_commodityPrivate* priv_a;

1497 }

◆ gnc_commodity_get_cusip()

const char* gnc_commodity_get_cusip ( const gnc_commodity *  cm)

Retrieve the 'exchange code' for the specified commodity.

This will be a pointer to a null terminated string of the form "AXQ14728", etc. This field is often used when presenting information to the user.

Note
This is a unique code that specifies a particular item or set of shares of a commodity, not a code that specifies a stock exchange. That is the namespace field.
Parameters
cmA pointer to a commodity data structure.
Returns
A pointer to the exchange code for this commodity. This string is owned by the engine and should not be freed by the caller.

Definition at line 996 of file gnc-commodity.cpp.

999  return GET_PRIVATE(cm)->cusip;
1000 }

◆ gnc_commodity_get_default_symbol()

const char* gnc_commodity_get_default_symbol ( const gnc_commodity *  cm)

Retrieve the default symbol for the specified commodity.

This will be a pointer to a nul terminated string like "£", "US$", etc. Note that for the locale currency, you probably want to look at the system-provided symbol first. See gnc_commodity_get_nice_symbol.

Parameters
cmA pointer to a commodity data structure.
Returns
A pointer to the default symbol for this commodity.

Definition at line 1088 of file gnc-commodity.cpp.

1089 {

Parameters
cmA pointer to a commodity data structure.
Returns
The number of fractional units that one of these commodities can be divided into.

Definition at line 1007 of file gnc-commodity.cpp.

1008 {
1009  if (!cm) return 0;
1010  return GET_PRIVATE(cm)->fraction;

commodity_namespaceAn aggregation of commodities. E.G. ISO4217, Nasdaq, Downbelow, etc.
mnemonicAn abbreviation for this stock. For publicly traced stocks, this field should contain the stock ticker symbol. This field is used to get online price quotes, so it must match the stock ticker symbol used by the exchange where you want to get automatic stock quote updates. E.G. ACME, ACME.US, etc.
cusipA string containing the CUSIP code or similar UNIQUE code for this commodity like the ISIN. The stock ticker is NOT appropriate as that goes in the mnemonic field.
