Benno Schulenberg 620553b795 input: filter out Ctrl+Meta keystrokes, as they can never be shortcuts
Note that DEL_CODE (0x7F) will never occur as input key code, because
it gets translated to KEY_DC in the input routine (or to KEY_BACKSPACE
when --rebinddelete is in effect).

Benno Schulenberg 6df50790cd input: prevent unintentional marking of text for shifted Meta keystrokes
The Shift detection on a Linux console was meant to affect only the
dedicated cursor-movement keys, not <Shift+Meta+character>.

This fixes https://savannah.gnu.org/bugs/?57598.

Benno Schulenberg f9baa4de71 syntax: nanohelp, nanorc: colorize the Sh-M-X format as a valid key name 2020-01-23 11:11:34 +01:00
Benno Schulenberg 1cd5005d06 bindings: allow to bind shifted Meta+letter combinations with Sh-M-X
As long as the user does not define any Sh-M-X bindings in their nanorc,
<Shift> and <CapsLock> will not have any effect on <Alt+letter> combos.
But as soon as any Sh-M-X combination is bound, <Shift+Alt+letter> will
be seen as different from the unshifted keystroke.

This kind of fulfills https://savannah.gnu.org/bugs/?54659.

Benno Schulenberg f7a3b996fa bindings: force the first letter in a key name to uppercase
So that converting it to a key code remains easy.

This fixes https://savannah.gnu.org/bugs/?57655.

Benno Schulenberg ea874112d8 tweaks: remove a feedback message that is never shown
A plain printable ASCII character (from 0x20 to 0x7E) can never be
a shortcut, so it also can never get reported as being unbound.

Benno Schulenberg 25d397e7b3 feedback: report Ctrl+Alt keystrokes as unbindable
When reporting them as simply unbound, the user might think that M-^X
keystrokes might somehow become bound.

Benno Schulenberg 54b97a6f03 bindings: allow to rebind also ^`, although it is synonymous with ^Space
Since ^@ is rebindable too and also a synonym of ^Space, it makes
more sense to allow the user to specify ^` instead, as it is an
unshifted keystroke on US keyboards.

Also, color ^` as valid in a nanorc file, and color ^` and ^@ in
the help viewer.

Benno Schulenberg 5e48c36877 rcfile: do set the meta flag for plain <Meta+ASCII> combinations
The meta flag needs to be suppressed only for the self-defined
<Meta+arrow> key codes.

This fixes https://savannah.gnu.org/bugs/?57643.

Bug existed since commit 5130c35b from a few hours ago.

Benno Schulenberg 9e3fca4021 rcfile: unbind keys by their key code instead of by their key string
Some key strings map to the same key code, so to unbind also a string's
synonyms, go through the list comparing against the key code.  It has
the additional advantage that it is faster: a plain value comparison
instead of a string comparison.

There is no need to compare also the meta flag, because plain printable
ASCII characters (from 0x20 to 0x7E) cannot be shortcuts, so when such
a character matches, it necessarily means it is a meta keystroke.

This fixes https://savannah.gnu.org/bugs/?57397.

Benno Schulenberg 5130c35b85 tweaks: avoid determining the key code from the key string twice
When assign_keyinfo() gets passed zero as key code, it will call
keycode_from_string() to determine the key code from the string.
So, remember the key code when keycode_from_string() gets called
the first time to avoid the second call.

Benno Schulenberg e01651cde1 pasting: retain the mark's position when it was set at the cursor
When the mark is set at the current cursor position, and then something
is pasted (either with ^U or from outside of nano), then this entire
pasted text should be marked -- just like when it had been typed.  So,
the mark's position should not be adjusted not only when it is located
before the cursor but also when it is at the same place as the cursor.

This fixes https://savannah.gnu.org/bugs/?57631.

Bug existed since version 2.0.7.

Benno Schulenberg 092711e412 tweaks: remove the now-unneeded code related to bracketed pasting
The suppression of auto-indentation, automatic hard-wrapping, and
tab-to-spaces conversion is now inherent in the way the reading-in
of a bracketed paste is handled by the previous commit: as a single
block of text.

Benno Schulenberg 0e6d693dc8 input: read in an external paste in one go, to allow undoing with one M-U
This makes an external paste (with mouse or <Shift+Insert>) behave
the same as an internal paste (^U), and also inherently suppresses
auto-indentation, automatic hard-wrapping, and tab conversion.

Benno Schulenberg f47ef539db display: skip zero-width characters on a Linux console, to avoid a mess
This is a workaround for the VT not being able to handle zero-width

This avoids https://savannah.gnu.org/bugs/?52954.

The problem has existed since forever, but has become noticeable
since the capability for line numbers was added in version 2.7.1.

Benno Schulenberg 416386edcd files: alert the user afterward when an overwritten file is being edited
(The ideal behavior would be that nano would warn the user beforehand,
before the file that is being edited by someone else gets overwritten,
but that would require many more changes.  So... just give a helpful
warning -- that's already better than it was.)

Benno Schulenberg 497f126bb2 files: write a lock file also for a new file and when the name changed
(When the new or changed name is that of an existing file AND this
file is being edited by some other editor (or nano itself), then the
behavior is rather strange: nano asks whether to continue, but the
file has already been overwritten and there is nothing the user can
do to cancel or revert things.  A later commit should improve this.)
