(Still, this does not allow a full escape sequence to be used as
the Cancel command, but I think that is an acceptable limitation,
because 1) nobody ought to be using --rawsequences, and 2) very
few people will bind Cancel to something like F3 or Ins.)
This improves the fix for https://savannah.gnu.org/bugs/?58825.
When checking (during a Search command) whether the user has pressed
the Cancel keystroke, look at ncurses' input stream directly instead
of at nano's own keystroke buffer, because the latter may contain the
copied keystrokes of a macro and we don't want to discard those.
(This does not yet allow a Meta keystroke to be used for Cancel, but
the next commit will fix that.)
This fixes https://savannah.gnu.org/bugs/?58825.
Bug existed since version 2.9.0, since the macro was introduced.
First mention the three main 'pieces' of the editor: Editing window,
Help viewer, and File browser. Then mention how to change settings:
with the toggles or with nanorc files.
There is no reason to deselect the region, as nothing has changed.
(This also retains the shift-selected region when a non-shortcut key is
typed in view mode, which makes sense, as again nothing was changed.)
This fixes https://savannah.gnu.org/bugs/?58980.
Bug existed since version 4.9, commit 0ed62e84.
Replace an obsolete question that doesn't have a good answer: setting
TERM to vt100 is unlikely to make the more complicated keystrokes work,
which are the ones that are most likely not to work.
When keypad() is set to FALSE, like for verbatim input, ncurses is
not waiting its fifty milliseconds after an ESC to see if another
code will follow it, so nano itself will have to pause a little.
Otherwise 'solitary' could get set to TRUE when in fact the ESC
is followed very closely by another code.
This fixes https://savannah.gnu.org/bugs/?58955.
Bug existed since version 2.6.2, commit f2150d3f.
Also when each character is just one byte, parse_verbatim_kbinput()
can produce two bytes; plus the terminating NUL that is three bytes.
This fixes https://savannah.gnu.org/bugs/?58959.
Bug existed since version 4.9, commit 03d296eb.
For installing and using nano, those two Changelogs are useless,
and for inspecting the history of nano, 'git log' is much better.
Only the most recent Changelog is somewhat useful for some users,
for walking in some detail through the changes that were made in
the last few versions.
This will not work for the deviant escape sequences for F1 to F5
on the Linux console nor for Alt+arrow on urxvt and such, but...
I can't be bothered to handle those too.
This fixes https://savannah.gnu.org/bugs/?58929.
Bug existed since commit be203832 from earlier today.
During verbatim input at most four integers are produced (the longest
possible unicode sequence), so use the value 999 to indicate a special
condition (a screen resize) that should not enter anything into the
buffer AND should not produce any error message or beep.
This fixes https://savannah.gnu.org/bugs/?58923.
Bug existed since version 5.0, commit 5899181a.
When Unicode Input has started (by typing 0 or 1 at the Verbatim Input
"prompt"), and something is typed that is not a hexadecimal digit, then
don't try to enter this character into the buffer but simply report it
as invalid and ignore it. Because most likely the user mistyped and
actually meant to enter a valid hex digit.
This fixes https://savannah.gnu.org/bugs/?58927.
The bug was old -- it existed since at least version 2.0.6.
Just like <Ctrl+Down> goes to the end of the buffer when after the
cursor there are only blank lines.
This fixes https://savannah.gnu.org/bugs/?58921.
Bug existed since version 2.6.2, since <Ctrl+Up/Down> were introduced.
The correct sequences begin with "Esc [" instead. I cannot find in the
histories of VTE and Gnome Terminal when these sequences were corrected.
Also exclude a bug check from the tiny version.
When we get an ESC from the keyboard, it might be the start of an
escape sequence, but the keyboard routines will need a little time
(tens of microseconds, probably) to get these codes to ncurses.
So, when doing verbatim input, pause a moment after an ESC.
This completes the fix for https://savannah.gnu.org/bugs/?58909.
Always interpret ESC followed by BS or DEL as <Alt+Backspace>.
This fixes https://savannah.gnu.org/bugs/?58910.
Bug existed since commit 40b03162 from one week ago,
since M-Bsp was hard-bound to deleting a word backwards.
(This could lead to unwanted behavior when the user wants to enter
a literal escape character (0x1B) while the input is somehow getting
stalled, because then a command keystroke after the M-V <Esc> would
get inserted verbatim too, instead of getting acted upon. But that
is a small price to pay for getting the correct behavior for both
M-V M-Bsp and M-V M-Enter.)
This fixes https://savannah.gnu.org/bugs/?58909.
Bug existed since version 2.6.3, commit 08c51cfd,
but also occurred erratically beforehand.
After commit 59bbc0b8 from five days ago (that made a divergent pipe
failure to be treated in the same way as the other two), this became
possible without having two different pipe-failure messages.
