Benno Schulenberg a6dae403e6 formatter: accept the formatted result also upon a nonzero exit status
For a nonzero exit status of the formatting program, report on the
status bar that the program "complained", but read in the (probably)
reformatted text anyway -- it can be easily undone with M-U.  Only
report failure when the intended program could not be run.

This fixes https://savannah.gnu.org/bugs/?57105.

Benno Schulenberg 4281b6becb commands: rename 'fixer' to 'formatter', to be less misleading
The word "fixer" sounds too much as if the command would be able
to fix mistakes or correct errors.  Especially when seen next to
"linter", it sounds as if one does a syntax check and the other
fixes the found mistakes.  (Although the command might in theory
be used for this, it is not its intended purpose.)

Benno Schulenberg 3c695664ec tweaks: elide a function call for the plain ASCII case
When dealing with a plain, seven-bit ASCII character, don't bother
calling is_cntrl_mbchar() but determine directly whether it is a
control character.  Also reshuffle things so that we don't compare
charlen == 1 when we already know it is 1.

Benno Schulenberg fa88fcc8f2 tweaks: rename a function, and elide a parameter that is always NULL
After the previous change, all remaining calls of parse_mbchar() have
NULL as their third parameter.  So, drop that parameter and remove the
chunk of code that handles it.  Also rename the function, as there are
already too many functions that start with "parse".

Benno Schulenberg 95ae124891 history: don't wait when there is something wrong with the history files
Do not wait for the user to press a key when there is some problem

on the status bar.  The precise error message is stored and will be
shown on the terminal when exiting from nano.

Benno Schulenberg b4a5fac744 tweaks: use a literal NULL instead of a variable that is NULL

Benno Schulenberg 022cc084a7 files: when opening a file for copying, it should NOT be created
Weird bug.  The first occurrence is probably never hit because the
existing file has been tentatively opened fourteen lines earlier,
but that looks superfluous: double work.  And the second occurrence
will not be hit because the temp file is unlikely to have disappeared.

Benno Schulenberg 7f8851caa8 statusbar: show only the first error message, with dots to indicate more
The old default behavior of showing the first three messages with a
long pause after each of them was annoying, and the final "Further
messages were suppressed" hid the relevant information.  So, when
there is more than one error message, just pause very briefly and
then add trailing dots to the first message.

This makes the 'nopauses' option a no-op.

Benno Schulenberg 23c36ba667 tweaks: remove two pointless re-inclusion guards
The nano.h file is included only by proto.h, and the proto.h file is
included just once by each src/*.c file.  The include guards for these
two header files serve no purpose.

(Include guards are useful when you have bunches of header files

Benno Schulenberg 0374708597 undo: put the cursor back on the original row for a full-buffer operation
When an operation that replaces the entire buffer is undone, the

undo item, arranging the viewport so that the cursor is back on
the original row -- the row where the operation was invoked.

For the three operations (justification, spell checking, and filtering)

in one go, pass the message that describes the operation to add_undo(),
so that the undo item does not need to be modified after the call.

This looks better, but does add some twenty NULL parameters elsewhere.

Benno Schulenberg f813fd0f4d rcfile: allow binding also F17...F24
For historical reasons the rebinding code allows binding F13...F16,
which on most terminals are typable with Shift plus F1...F4.  But,
at least on an Xfce Terminal, Shift plus F1...F12 produce F13...F24.
On a Linux console, Shift plus F1...F8 produce F13...F20.  So: allow
to bind the full shifted F13...F24 range.  It costs no extra code
and makes things more rounded.

When there are fewer than four menu items, act as if there are four:

Until now, when there were two menu items, their clickable width would
be the full width of the screen, which was overwide.  But when there
was just one menu item, its clickable width would suddenly be as small
as when the menu had the maximum number of items (12 for an 80-column
screen).  This was odd.

Also, slightly simplify another computation.

Benno Schulenberg b3ace4d8f6 tweaks: don't burden all menus with something meant for the WriteOut menu
The first_sc_for() function is somewhat costly, so avoid calling it
when it is not necessary.

Most menus have either so many entries that unbinding some keys does
not reduce the number of shown entries, or they have so few entries
that each entry already has space enough and will not profit from
having more room available.  But the WriteOut menu is an edge case.
Most translators don't use --tempfile and translate the key tags for
the WriteOut menu making use of all 17 positions that are available
for each of them.  This makes that when --tempfile is used, some of
those tags get truncated.  This is not so bad, because --tempfile is
normally not used.  But when it isn't used (when the discardbuffer
function isn't bound), the WriteOut menu should make full use of the
available width to avoid truncating any translated tags.

Benno Schulenberg 3644d51b97 new feature: a 'tabgives' command to define what the Tab key produces
The 'tabgives' command is syntax-specific and should be followed by a
string containing the character(s) that a single press of the <Tab> key
should produce -- most likely a single TAB or a small bunch of spaces,
but any string is allowed.  This overrides the 'tabstospaces' option.

When one wants to make sure <Tab> inserts always four spaces and never
a TAB when editing a Python file, one could add to one's nanorc:

  extendsyntax python tabgives "    "

where there are four spaces between the quotes.  And when one wants
to ensure, when editing a Makefile, that <Tab> always inserts a TAB
and never spaces, independent of what tabstospaces is set to, one
could add to one's nanorc:

  extendsyntax makefile tabgives "	"

where there is a literal TAB character between the quotes.

be single-byte printable ASCII characters, so their case should come
first in the main loop of display_string().

In addition, the function was used just once, had a weird return value,

Make use of the fact that any single-byte character always occupies
just one column, and call the costly mbtowc() and wcwidth() only for
characters that actually are multibyte.

Benno Schulenberg 33fea90bcd justify: remove "--" from the quoting regex, to avoid false paragraphs
The use of a double dash (for an option name or as sentence separator)
is too common to allow it to be seen always as a comment introducer.
Users of Lua and Postgres will have to redefine 'quotestr' themselves
if they want to be able to rewrap block comments with ^J.

The other characters that were added in commit c5a72103 (!, %, and ;)
are less problematic because they tend to be glued to the end of words,
so they are unlikely to appear at the start of a line.

old data, so that we can simplify things.

This "holder" information is needed for every cut and paste and other

The /etc/nanorc file should not define any syntax directly (and
preferably not include any either, to not slow startup down with

the command can be added to the syntax itself -- it would be better

Benno Schulenberg d946f38a2b files: when needed, reconnect the keyboard and reenter curses mode
When after reading a file we are not in curses mode, it means we have
read data from standard input, either from the keyboard or from a pipe.
In the latter case, we first need to reconnect standard input to the tty.
And in both cases, we then need to reenter curses mode before being able
to display the number of lines that were read (or an error message).

So, move the reconnecting code from scoop_stdin() to its own function,
and call this function from read_file() when needed.

Benno Schulenberg 35a791dee5 tweaks: remove two unneeded checks for NULL
If the rest of nano is correct, then these checks are superfluous and
only slow the loops down.  But if there is some incorrect code, then
let nano crash on dereferencing NULL so we can find and fix the bug.

Benno Schulenberg 98ffb19746 tweaks: stop checking for a NULL result from line_from_number()
No one ever reported seeing the message that was removed in commit
c039aaad one month ago, so most likely the code is correct and nano
never calls line_from_number() with a non-existent line number.

Benno Schulenberg b512e253b6 tweaks: drop an unneeded parameter from open_file()
The 'quiet' parameter is only used when opening a help-text tempfile
or a spell-checked tempfile, and these files necessarily exist, so
'quiet' will never be checked for them.  But in the weird case that
the help-text tempfile could not be opened, it is not a problem that
"New File" gets printed to the status bar because nano will crash
shortly afterwards.  And when the spell-checked tempfile could not
be opened, a "Not Found" message is appropriate, but nano will crash
in this case too.

Benno Schulenberg 137c4467ef speller: ensure that a Shift-selected region is retained
For both an integrated and an external spell check, fake the Shift key

Benno Schulenberg e3e81879b1 tweaks: condense the setup of the two signal handlers for Ctrl+C
Don't bother checking for an error from sigaction(), because the only
things it could error out for is when it is passed an invalid signal
(which SIGINT isn't) or oldaction/newaction would point to memory that
is outside of nano's control (which is obviously not the case).

Also, the setup of signal handlers during startup does not check for
errors, so why do it here?

Benno Schulenberg 12bf3bfce4 feedback: don't clear off possible error messages after a spell check
If functions deeper down would put up some message on the status bar,
it should not be cleared.  The chance that messages from a spell-check
program stay onscreen is minute: the edit window is fully refreshed,
the status bar is fully drawn, and the help lines (if there are any)
are redrawn.  Only the title bar is not refreshed, but the chance that
an error message has spilled onto the top row...  And anyway, the
spell checker should not print any error messages at all.

Brand Huntsman cba9d8d05e rcfile: fully parse a syntax file only when needed
When parsing an included syntax file, stop reading when a command other
than 'syntax', 'header' or 'magic' is encountered.  The syntax file is
fully parsed the first time that a file needs it.  Each 'extendsyntax'
command is stored for unloaded syntaxes and applied after the syntax
is loaded.

Closing a buffer does not unload the syntax, even if no longer used by
another buffer.

Brand Huntsman 0e29c2a24a rcfile: store errors and display them when nano terminates
This is needed to implement the demand loading of syntax files, as any
errors that these files may contain would otherwise overwrite things on
the screen and the messages wouldn't be on the terminal when nano exits.

It also allows nano to start up on a Linux console when there are errors.

Benno Schulenberg 1b2018e921 files: check for writability by the access bits, not by trying to append
Trying to append does not work on a fifo, and we'd like to be able to
open a fifo again.  Also, the append test causes a close event for the
given file at the moment of opening it, which makes using 'inotify' for
waiting for this file to be closed useless.

Commit f8f90272 added the append test, but the original request
(https://lists.gnu.org/archive/html/info-nano/2009-05/msg00000.html
by Damien Joldersma) asked only for a warning when the user did not
have enough privileges to write to the file.

So, drop the append test and just check the access bits.

Benno Schulenberg 26642a39c3 files: allow a given file to be a special file but not a directory
The original requests (https://bugs.debian.org/551717 by Paul Wise,
and https://savannah.gnu.org/bugs/?45383 by Mike Frysinger) asked
only that specifying a directory instead of a file name should not
open a new buffer.  But commit 98ffb642 excluded everything that was
not a normal file.  This avoids a hang when the user accidentally
tries to open a pipe or a socket, but also prevents any user from
doing so on purpose.  And opening a fifo can be useful when wanting
to handle sensitive data that shouldn't be stored on disk.

This prepares the fix for https://bugs.debian.org/583196.

Benno Schulenberg 341601e1a2 bindings: at a Yes-No prompt, accept also ^N and ^Q for "No"
When wanting to exit after having modified a buffer by mistake, I don't
want to politely answer a question by typing precisely an unmodified N,
I want to give a command: ^N, meaning *No!*.  Or seen another way: I
don't want to be obliged to let go of the Ctrl key before typing N.

When at startup --tempfile was used, the user can discard a modified
buffer with ^O ^Q.  It would be nice when (without --tempfile) ^X ^Q
would work too.

Benno Schulenberg fcad442d80 tweaks: declare a function as const and let its allocated string leak
Avoiding this leak is more trouble than it's worth: invocation_error()
will be called seldomly, and when it is called, the user will probably
quickly exit from nano to fix things.

Also declare the speller functions as const again, so they don't give
the impression that their result can be freed.

Benno Schulenberg 34d22d3f00 wrapping: improve the persistence of the prepending behavior
Now you can have a look elsewhere in the buffer (and even delete
or paste stuff there) and when you return to the original line
and continue typing, any spillover from automatic hard-wrapping
will spill over onto the same line it spilled over to before.

You can even switch to a different buffer and return and continue
typing, and stuff will still spill over to the same line.

In the bargain, this gets rid of a bit of flag-resetting code
that was run for many keystrokes, in most cases needlessly.

Benno Schulenberg 1c707d4f99 unindent: ensure that a partial line gets displayed properly afterwards
When only the trailing chunk of a line is displayed on the top row of

the number of chunks, then the starting point of the viewport needs
to be re-evaluated.  For simplicity, do this always when something is
unindented.

Benno Schulenberg 82f1ce8ebf bindings: remove the jumpy-scrolling toggle entirely
It is still possible to use --jumpyscrolling on the command line or
'set jumpyscrolling' in a nanorc file, but a user will have to restart
nano when they decide they want chunky instead of smooth scrolling,
a decision that should be rather rare.

This frees up the M-S keystroke to be reused for toggling softwrap.

Benno Schulenberg 2552307064 options: remove -f (--finalnewline); go back to auto-adding this newline
For relatively inexperienced users (as most users of nano probably are)
it is far better that nano produces POSIX text files by default, where
each line ends with a newline character.  This means that these files
will "print" properly (not gluing the next prompt at the end of the
last line), tools will see and process each line of them, and, while
editing, adding text at the end is easier.
