kill-region is the usual subroutine for killing text. Any command
that calls this function is a “kill command” (and should probably have
‘kill’ in its name). kill-region puts the newly killed text in
a new element at the beginning of the kill ring or adds it to the most
recent element. It determines automatically (using last-command)
whether the previous command was a kill command, and if so appends the
killed text to the most recent entry.
This function kills the text in the region defined by start and
end. The text is deleted but saved in the kill ring, along with its
text properties. The value is always nil.
In an interactive call, start and end are point and the mark.
If the buffer or text is read-only, kill-region modifies the kill
ring just the same, then signals an error without modifying the buffer.
This is convenient because it lets the user use a series of kill commands to
copy text from a read-only buffer into the kill ring.
If yank-handler is non-nil, this puts that value onto the
string of killed text, as a yank-handler text property.
Voir la section Yanking. Note that if yank-handler is nil, any
yank-handler properties present on the killed text are copied onto
the kill ring, like other text properties.
If this option is non-nil, kill-region does not signal an
error if the buffer or text is read-only. Instead, it simply returns,
updating the kill ring but not changing the buffer.
This command saves the region defined by start and end on the
kill ring (including text properties), but does not delete the text from the
buffer. It returns nil.
The command does not set this-command to kill-region, so a
subsequent kill command does not append to the same kill ring entry.
Don't call copy-region-as-kill in Lisp programs unless you aim to
support Emacs 18. For newer Emacs versions, it is better to use
kill-new or kill-append instead. Voir la section Low-Level Kill Ring.
