Benno Schulenberg 157c7b1bc4 rcfile: explicitly check for disallowed keywords in included files
This fixes https://savannah.gnu.org/bugs/?54441.

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-|.

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outdated.

Benno Schulenberg 54a4123d4c bindings: remove the 'searchagain' function entirely

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

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).

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.

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 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".

Benno Schulenberg d92142c66a easter: show the crawl only when there is room enough for the lines
The crawl needs at least five rows to be perceived as a crawl, and
the widest line is 31 characters (ignoring translations, which might
be even longer).  Formerly, when only two or three rows were available,
nothing was shown at all, which was puzzling.  So, better do the credits
only when there is room enough for them, and print a message otherwise.

Benno Schulenberg 063a8b0870 startup: show the correct number of lines when opening multiple files
When switching to a different buffer, don't just show its name but
also the number of lines it contains.  This is useful extra info.

Then use this same message when at startup multiple files are opened
and (after reading them all) we switch back to the first buffer.

(This loses, when multiple files are opened, the information about
format conversion that nano still shows when a single file is opened,
but... this bug has shown that people don't really look at this line
anyway, so... let it be.  The info can still be seen when writing out
the file with ^O.)

Devin Hussey b2ff574678 files: speed up reading by using getc_unlocked() instead of getc()
Unlike glibc, which in getc() locks the file only when it is needed,
FreeBSD and Bionic libc will always lock the file, causing a massive
slowdown, as the system has to create and destroy a mutex each time
getc() is called.

Avoid that massive overhead by locking the file before starting to read
and unlocking it after reading is complete, and using getc_unlocked() to
read each byte.  This makes reading on FreeBSD/macOS and Android anywhere
from 2 to 6 times faster, and on glibc roughly seventy percent faster.

This partially addresses https://savannah.gnu.org/bugs/?50406.
