This function copies specifier to dest, or creates a new one
if dest is nil
.
If dest is nil
or omitted, a new specifier will be created
and the specifications copied into it. Otherwise, the specifications
will be copied into the existing specifier in dest.
If locale is nil
or the symbol all
, all
specifications will be copied. If locale is a particular locale,
the specification for that particular locale will be copied. If
locale is a locale type, the specifications for all locales of
that type will be copied. locale can also be a list of locales,
locale types, and/or all
; this is equivalent to calling
copy-specifier
for each of the elements of the list. See
specifier-spec-list
for more information about locale.
Only instantiators where tag-set (a list of zero or more tags) is
a subset of (or possibly equal to) the instantiator’s tag set are
copied. (The default value of nil
is a subset of all tag sets,
so in this case no instantiators will be screened out.) If exact-p
is non-nil
, however, tag-set must be equal to an
instantiator’s tag set for the instantiator to be copied.
Optional argument how-to-add specifies what to do with existing
specifications in dest. If nil
, then whichever locales or locale
types are copied will first be completely erased in dest.
Otherwise, it is the same as in add-spec-to-specifier
.
This function removes specification(s) for specifier.
If locale is a particular locale (a buffer, window, frame, device,
or the symbol global
), the specification for that locale will be
removed.
If instead, locale is a locale type (i.e. a symbol buffer
,
window
, frame
, or device
), the specifications for
all locales of that type will be removed.
If locale is nil
or the symbol all
, all
specifications will be removed.
locale can also be a list of locales, locale types, and/or
all
; this is equivalent to calling remove-specifier
for
each of the elements in the list.
Only instantiators where tag-set (a list of zero or more tags) is
a subset of (or possibly equal to) the instantiator’s tag set are
removed. (The default value of nil
is a subset of all tag sets,
so in this case no instantiators will be screened out.) If exact-p
is non-nil
, however, tag-set must be equal to an
instantiator’s tag set for the instantiator to be removed.
This function applies func to the specification(s) for locale in specifier.
If optional locale is a locale, func will be called for that
locale.
If locale is a locale type, func will be mapped over all
locales of that type. If locale is nil
or the symbol
all
, func will be mapped over all locales in
specifier.
Optional ms-maparg will be passed to ms-func.
func is called with four arguments: the specifier, the
locale being mapped over, the inst-list for that locale, and the
optional maparg. If any invocation of func returns
non-nil
, the mapping will stop and the returned value becomes the
value returned from map-specifier
. Otherwise,
map-specifier
returns nil
.
Given a specifier locale, this function returns its type.
