Here is a description of the functions that can be used to work with properties.
Get all properties of the entry at point-or-marker POM.
This includes the TODO keyword, the tags, time strings for deadline,
scheduled, and clocking, and any additional properties defined in the
entry. The return value is an alist. Keys may occur multiple times
if the property key was used several times. POM may also
be nil
, in which case the current entry is used. If
WHICH is nil
or all
, get all properties. If
WHICH is special
or standard
, only get that subclass.
Get value of PROPERTY for entry at point-or-marker
POM. By default, this only looks at properties defined
locally in the entry. If INHERIT is non-nil
and the
entry does not have the property, then also check higher levels of the
hierarchy. If INHERIT is the symbol selective
, use
inheritance if and only if the setting of
org-use-property-inheritance
selects PROPERTY for
inheritance.
Delete the property PROPERTY from entry at point-or-marker POM.
Set PROPERTY to VALUES for entry at point-or-marker POM.
Get all property keys in the current buffer.
Insert a property drawer for the current entry. Also
Set PROPERTY at point-or-marker POM to VALUES. VALUES should be a list of strings. They are concatenated, with spaces as separators.
Treat the value of the property PROPERTY as a whitespace-separated list of values and return the values as a list of strings.
Treat the value of the property PROPERTY as a whitespace-separated list of values and make sure that VALUE is in this list.
Treat the value of the property PROPERTY as a whitespace-separated list of values and make sure that VALUE is not in this list.
Treat the value of the property PROPERTY as a whitespace-separated list of values and check if VALUE is in this list.
Hook for functions supplying allowed values for a specific property.
The functions must take a single argument, the name of the property,
and return a flat list of allowed values. If ‘:ETC’ is one of the
values, use the values as completion help, but allow also other values
to be entered. The functions must return nil
if they are not
responsible for this property.
