A filename might contain spaces, so we can't look for the numbers
(the second and third elements) starting from the head of the line
-- we have to start at the tail and work backward.
This fixes https://savannah.gnu.org/bugs/?49879.
So they will not break a line in the positionlog file in two.
(Strangely, the reading in of such a log file already decodes
nulls back into newlines.)
This fixes https://savannah.gnu.org/bugs/?49877.
Most full paths are needed only temporarily and will be freed within
milliseconds. Only 'full_operating_dir' and 'backup_dir' continue to
exist for the whole current session. Any partition, too, will soon be
unpartitioned, so the extra reallocation is just a waste of time.
The functions read() and fwrite() take size_t, not ssize_t.
And line numbers in the file should be displayed as a long type instead
of an int, since the effective type of ssize_t is not int, but long.
Achieve this by reusing the code that gives feedback when trying to
save a buffer while using --tempfile and the file has no name yet.
This fixes https://savannah.gnu.org/bugs/?48622.
If it would, the returned file descriptor would make nano crash,
because the corresponding stream has not been opened. And when
returning zero instead (as the code did originally), nano would
open an empty buffer, although it claims to be reading the file.
In short: I think this is a leftover of an attempted fix of
https://savannah.gnu.org/bugs/?25297, from commit 2823c99.
Add the keycodes and routines to allow the user to forego setting the
mark explicitly (with M-A / ^6) and instead quickly select a few words
or lines by holding down Shift together with the movement keys.
(Some combinations with Shift are swallowed by some terminal emulators.
To work around some of those, the combinations Shift+Alt+Left/Right work
as Shift+Home/End and Shift+Alt+Up/Down work as Shift+PageUp/PageDown.)
Don't make it the responsibility of the executed functions to restore
the list of shortcuts of the edit window. Just detect whether another
menu was displayed, and if so, redisplay the main menu.
Specifying an operating directory should either lead to a successfull
confinement, or nano should fail to start.
(Also: save the terminal settings as soon as possible, so that an early
die() will not restore uninitialized values.)
This fixes the first part of https://savannah.gnu.org/bugs/?47798 properly.
This fixes https://savannah.gnu.org/bugs/?48103.
(The fix is wasteful -- it should only discard the multidata if actually
the name *did* change, *and* if the applicable syntax changed.)
