There were no calls of statusbar() or statusline() before curses mode
was entered. But since the previous commit curses mode is entered
even earlier, so...
A background color *can* be bright (in the sense of lighter, shinier).
It's just that the background cannot be bold. Only the typeface used
on the foreground can be bold (if the terminal supports it). So, let
"bright", when used with a background color, simply mean "light".
This makes it possible to avoid the misnamed prefix "bright". It is
misnamed because (on current terminal emulators, when the brightening
of bold is switched off) it just makes the typeface bold, not the color
brighter. The prefix "light" will now only make the color brigther,
and the modifier "bold" will just make the typeface bold (on terminal
emulators, when the brightening of bold is switched off).
On a Linux console, which is not capable of bolding the typeface,
"bold" will brighten the color.
This fully fulfills https://savannah.gnu.org/bugs/?58503.
The prefix "bright" will continue to make the color brighter AND/OR
make the typeface bold (depending on how the terminal is configured
and on its capabilities), but the prefix "light" will just make the
color brighter (if the terminal can do that).
The prefix "bright" continues to do the same as what it did before,
to not change the appearance of user-defined syntaxes. And having
an option to change the meaning of "bright"... would be confusing.
This partially fulfills https://savannah.gnu.org/bugs/?58503.
This way we don't have to probe twice, and the result is accurate also
when nano is reading data from standard input. Standard output should
always be connected to a terminal, as nano is not meant to operate
without a screen.
Each listing of a name is preceeded by a call to wmove(), so there
is no need for an initial wmove(). And after writing "more" on the
bottom row of the edit window, the loop is terminated, so there is
no need to check that this is the first item on the bottom row.
And when the margin changes (when line numbers are switched on or off,
or when the buffer grows or shrinks), and when a piece of text from a
different buffer with a different margin is pasted.
This fixes https://savannah.gnu.org/bugs/?58517.
Bug existed since commit 9a9f36fc from yesterday.
Instead of storing for each line the ordinal number of the first chunk
in that line, simply store the number of extra chunks in the line.
It now takes some more computation to actually draw the scrollbar, but
it saves a lot of computation when just inserting or deleting characters
(when using --softwrap and causing a change in chunk count).
This fixes https://savannah.gnu.org/bugs/?58510.
Bug existed since commit 6bccedb3 from two days ago.
There is no need to be explicit about not having saved the buffer --
it is implied in the "Too many". And anyway, no one is ever going to
see this message -- who will have a hundred thousand .save files?
Trimming this message makes the tiny version smaller.
Also, rewrap a neighbouring line.
By default, the position indicator is off. It can be turned on
by passing -q or --indicator on the command line, or by adding
'set indicator' in your nanorc file.
A new member ('chunk_nr') is added to each 'linestruct', to store
the serial number of the first chunk of that line, so that, when
softwrap is on, the scroll-bar thing can be computed relative to
chunks instead of relative to actual lines.
To guarantee that 'chunk_nr' is correctly synced, the buffer is
renumbered whenever the number of chunks in a line changes, and
also when softwrap is toggled on, and when buffers are switched.

This displays a scrollbar-like thing on the right edge of the screen,
giving a rough indication where in the buffer the text that is being
shown in the viewport is located, and how large/small a portion of
the buffer this text is.
(Support for softwrapping, and an option to turn the indicator on,
will arrive in subsequent commits.)
This fulfills https://savannah.gnu.org/bugs/?57956.

(Unfortunately, this means that ^L cannot be used for the
Linter in the "Execute Command" menu.)
This fixes https://savannah.gnu.org/bugs/?58469.
Bug existed since around version 2.1.0.
Nano would beep (and report "Unknown sequence") only when in the main
edit window, in the help viewer, or in the file browser. But the same
keystroke at a prompt would be enigmatically silent.
Also, in the file browser, nano would leave the cursor at the end of
the "Unknown sequence" message when --showcursor was used.
This fixes https://savannah.gnu.org/bugs/?58490.
Bug existed (in this form) since around version 2.7.4,
and in a worse form since around version 2.3.5.
A help text is contained in a normal buffer (since quite a while now),
so cursor placement should work like in a regular edit window.
Also, remove an unneeded switching on of the cursor -- it is already on
as nano is waiting for keyboard input.
This fixes https://savannah.gnu.org/bugs/?58489.
Bug existed since version 3.2, commit 10d9742c, since --showcursor
shows the cursor also in the help viewer.
If a replacement changed the matching of a multiline coloring regex,
then wipe the existing multiline data and recalculate it for the whole
buffer.
There is no need to redraw the current line (let alone the whole window)
directly after a replacement, because if there is a next occurrence, the
edit window will be redrawn then in order to spotlight that occurrence;
and if there is no other occurrence, the edit window will be redrawn in
the main loop because there has been at least one replacement.
This fixes https://savannah.gnu.org/bugs/?58481.
Bug existed (in this form) since version 2.7.5. Before that,
the miscoloring could happen even without scrolling.
When resizing the screen or toggling the help lines or refreshing
the screen with ^L, what used to be total_refresh() would first call
what used to be total_redraw(), to tell ncurses to redraw whatever
had been on the screen so far, before proceeding to fully redraw the
content of the title bar and the edit window and the bottom bars.
That was duplicate work.
Thus, rename total_redraw() to total_refresh(), so that ^L in the
edit window, help viewer, and file browser will redraw the screen
just once. This also preserves whatever was on the status bar
(when --quickblank isn't used).
Rename the old total_refresh() to draw_all_subwindows() and call
this routine when resizing the screen or toggling the help lines
or returning from the credits crawl.
This makes that the M-F toggle stays roughly in the same place when
toggling between "Read File" and "Execute Command", and groups the
six special commands together.
This makes suspension more discoverable, and allows the user to rebind
^Z in the main menu without losing the ability to suspend nano.
This drops the ^X (Flip Execute) toggle from the menu -- keeping it
would make an ugly uneven number and would reduce the space for each
menu item too much (clipping "Full Justify" and "Cut Till End") --
but it is still present as a blind toggle.
Make the "Execute Command" menu accessible also with a single keystroke
(^T), not just with a double one (^R^X). This is useful, because no one
will suspect that "Execute Command" can be found behind "Read File".
To not disturb muscle memory too much for people who are used to ^T
invoking the Spell Checker, a second ^T will invoke it.
Instead of creating a special Tools menu, add the five functions that
affect the whole buffer to the "Execute Command" menu. There is room
for these five functions there, and they kind of fit in because three
of them (Speller, Linter, and Formatter) actually invoke an external
command, and Full Justify could have been implemented externally, and
the destructive Cut Till End ought to have required a double keystroke
since the beginning.
