The extra variable is not needed, because when having read from
standard input, the filename will simply be empty. It will not
be empty for any other file that was read.
The dash doesn't have to be the first non-option argument: it can
be anywhere among the filenames -- there can even be multiple ones
(but don't mention this explicitly).
Negative arguments of 'fill' are bright green since a few commits.
So now color all valid numeric arguments in that same style -- the
yellow was hard to see on a dark background anyway.
Also, color a zero tabsize as invalid.
A recent change (8dffb00f) removed this ability. This change restores
it, and also allows reading from standard input multiple times -- maybe
not useful, but it works.
Also when a dash is the first "file" mentioned on the command line,
nano should show this buffer at startup and not the next.
This fixes https://savannah.gnu.org/bugs/?51207.
In the tiny version, Ctrl+Left and Ctrl+Right are available only
in the editor itself and in the file browser.
This fixes https://savannah.gnu.org/bugs/?51173.
The old praxis of calling total_refresh() upon a SIGCONT was confusing,
because the screen would look as if nano had returned from suspension,
but in fact the shell was still active.
Instead of calling total_refresh(), put a no-op key into ncurses' buffer,
so that, when nano actually does return out of suspension (through 'fg'),
this key will be read and discarded, upon which nano will go sit and wait
for the next key, just before which it calls doupdate(). The latter is
all we need to get the entire screen restored.
This also fixes https://savannah.gnu.org/bugs/?51131 for "tiny".
When receiving a SIGCONT, don't call regenerate_screen() directly
but act as if a SIGWINCH occurred. Also insert a dummy key, and
thus let the relevant input routine redraw the relevant subwindows.
Use KEY_F0 as the dummy key, as both Ncurses and Slang know it, and
it should normally do nothing at all.
This fixes https://savannah.gnu.org/bugs/?51124.
When we are in the file browser, browser_refresh() will take care of
redrawing the title bar and the file list, so total_refresh() should
leave those two subwindows alone in that case.
This fixes https://savannah.gnu.org/bugs/?51147.
Achieve this by making the suppression flag global, so that we can
just reset it instead of making an improper call of do_cursorpos().
This fixes the secondary part of https://savannah.gnu.org/bugs/?51134.
