Make sure the inserts of the spell-checked text are undoable, and no
longer discard the undo stack after running the alternate spell checker.

Benno Schulenberg 4c66a6259c tweaks: slightly improve error message when vital function is unmapped
This fails to fix https://savannah.gnu.org/bugs/?54449, because
it would take far too much code for an exceptional case.

Benno Schulenberg db1893ef2d syntax: nanorc: recognize 'yesno' as a valid menu to bind/unbind keys in 2018-08-06 18:05:10 +02:00
Benno Schulenberg ad79a4fcfb rcfile: ensure that in the yesno menu Cancel is bound to some keystroke
(In the Search and Replace menus Cancel is not essential.  And in the
Goto Line menu Cancel is not needed at all: a simple <Enter> after an
empty answer works fine.)

This fixes the second part of https://savannah.gnu.org/bugs/?54447.

Benno Schulenberg ac102a7516 tweaks: show "Space" and "Bsp" in the help text of the browser
These keys make more mnemonic sense for scrolling than F7 and F8.

Also adjust the nanohelp syntax to cover the lone word "Space".

Benno Schulenberg d249233ea7 bindings: unassign the M-? keystroke, to free it up for future use
There are at least three other ways to achieve the thing that it did:
^End, M-/, and ^W^V.  No need to have a fourth way by default.

For symmetry, also unassign the corresponding binding for M-|.
2018-07-31 20:36:27 +02:00
Benno Schulenberg 33fb54c75f bindings: reassign the M-| keystroke to 'cutwordleft' by default
The 'cutwordright' function has gotten ^Delete as its default binding,
so the 'cutwordleft' function needs a default binding too -- also to
keep the items on the two help lines nicely paired.  M-| was chosen
because it is close to the Backspace key on many keyboard layouts.

Benno Schulenberg 60ee4408be signals: don't call a print routine in a signal handler
Print routines are not asynchronous-safe.

But... the only reason the call of kill() could return an error code
is when the relevant process has already terminated -- which is not
a problem, because that was the goal of calling kill().

This fixes https://savannah.gnu.org/bugs/?54409.

Benno Schulenberg 9a47a9c4c0 rcfile, docs: no longer recognize nor mention 'set backwards'
The option has been a no-op since 2.9.0.  And now that the
^W/^Q/M-W/M-Q set is available, 'set backwards' is entirely
outdated.

David Lawrence Ramsey 9c8e40b442 bindings: make "n" work again in file browser and help viewer

Benno Schulenberg 54a4123d4c bindings: remove the 'searchagain' function entirely
The user is obliged to make use of 'findprevious' and 'findnext' instead.

Also, adjust the description of 'wherewas' to its wider availability.

David Lawrence Ramsey 7a31507167 bindings: make ^Q start a backward search also in the file browser
This makes the four search keystrokes (^W/^Q/M-W/M-Q) available in
all three areas of nano: editor, help viewer, and file browser.
2018-07-29 11:43:13 +02:00
Benno Schulenberg 7f2031006a bindings: make ^Q and M-Q available also in the help viewer
As the help viewer is almost a normal buffer, commands that make sense
-- like searching backwards, and searching the previous occurrence --
should work in the help viewer too.

In addition, show all Search commands prominently in the help lines of
the help viewer, so that users are likely to notice them and will maybe
infer that they work in the editor itself too.

This fixes https://savannah.gnu.org/bugs/?54368.

Benno Schulenberg 7e18b91ead help: move "Search Again" away from "Find Next" and "Find Previous"
Put "Where Was" in its place, to make the symmetry of ^W/M-W/^Q/M-Q
somewhat clearer.  Also, conditionally reshuffle "Save File", to try
and keep menu items nicely paired.

Benno Schulenberg f82eefa303 tweaks: exclude the file-prepending code from the tiny version
The prepending and appending toggles are not available in tiny nano,
so there is no need to have the code either.

Benno Schulenberg 8e1ce7034d search: include 'findprevious' and 'findnext' in the tiny version

Now M-Q will be functional also in a tiny nano.

Benno Schulenberg c4d09cc24b text: add auto-whitespace to the file size after creating the undo item
The undo item for ENTER should record the file size *before* the amount
of auto-indentation whitespace is added to it.

Benno Schulenberg d04c8f88f1 docs: say that 'cutwordright' is now bound to <Ctrl+Delete> by default
Also, suggest to rebind ^H to 'cutwordleft' so that <Ctrl+Backspace>
will delete the word to the left of the cursor (on some terminals).
2018-07-22 19:27:50 +02:00
Marco Diego Aurélio Mesquita a67f6c6031 input: erase the next word when Ctrl is held while pressing Delete
Bind the until-now unbound function 'cutwordright' to <Ctrl+Delete>.
The complementary function, 'cutwordleft', is not bound by default
because on many terminals the keystroke <Ctrl+Backspace> generates
^H -- the canonical ASCII backspace character.  We cannot change the
existing action of ^H without upsetting some users.

Benno Schulenberg 8d8f5788ce rcfile: do not accept rebinding F0 nor function keys above F16
To match the documentation and to match what the nanorc.nanorc
colors as valid.

In theory it would be possible to allow rebinding also F17...F63,
but nano does not recognize escape sequences for these high-order
function keys.  As no one ever complained about unknown sequences
when pressing function keys, I am guessing that no one has these
high-order keys, or at least that no one uses them.

This fixes https://savannah.gnu.org/bugs/?54332.

Benno Schulenberg 05592a84ec completion: when the cursor is not after a word fragment, say so
Instead of being entirely silent when ^] is hit after whitespace
or punctuation, report what is lacking -- similar to M-] saying
"Not a bracket" when the cursor is not sitting on a bracket.
This makes the ^] keystroke more discoverable.

Benno Schulenberg c46696d40c tweaks: delete some old debugging code that no longer seems useful 2018-07-18 19:53:44 +02:00
Benno Schulenberg bfe65af6f3 bindings: bind M-Q to 'findprevious' by default, and M-W to 'findnext'
This makes things symmetrical: ^W starts a forward search, ^Q starts
a backward search, M-W searches the next occurrence forward, and M-Q
searches the next occurrence backward.

The Tabs-To-Spaces toggle is moved to M-O, and thus the More-Space
toggle is no longer bound by default.

Benno Schulenberg 2fef7f647d input: stop a modified Delete key from entering stuff into the buffer
When using option -K on an xterm-like terminal, pressing <Shift+Del>,
<Alt+Del>, or <Ctrl+Del> would enter "2~", "3~", or "5~", respectively,
into the buffer.  Now it will just report an "Unknown sequence".
