First it expected a single digit number, but this way it makes it more easy and
logical to add Sun function keys: ESC [ num z
For archive/reference Sun function keys relevant to sfeed_curses:
num =
214: home
216: page up
220: end
222: page down
Noticed on OpenIndiana/Illumos.

This should also suppress a compiler warning of an unchecked write() return
value.
|
|
Use errx, time(NULL) does not set errno. For sfeed_curses reset errno so it
doesn't print a random error if it failed.
POSIX recommends checking against (time_t)-1 on failure.
Note that some implementation, like the OpenBSD man page says time() cannot
fail.

Otherwise a character like \xa0 (160) would be negative and goto the event,
since a negative return value in readch() is used for errors or reserved for
signal handling.
Noticed while testing mouse X10 encoding with extended buttons, like button 7:
SFEED_AUTOCMD="l$(printf '\x1b[M\xa0!!')j" ./sfeed_curses ~/.sfeed/feeds/*

On an unknown or invalid sequence just use the key handling like the other keys
do.
|
|
When reading data from stdin and changing the URL file externally in some way
and then pressing 'R' would not redraw (and highlight/unhighlight) the marked
items.

|
vdprintf() was changed back to vfprintf() in commit 06bb4583, but the write was
not changed.
Change it to be more consistent and use the stdio buffered functions/macro.
|
|
Add autocmd comment.

\x1b[1~ home (putty and some terminals).
\x1b[7~ urxvt home.
\x1b[8~ urxvt end.
Refactor repeated code also.

Some curses implementations have tparm(char *) (BSD and older ncurses), some
have tparm(const char *).
The older POSIX specification had: tparm(char *):
https://pubs.opengroup.org/onlinepubs/7908799/xcurses/term.h.html
Just cast it to char *. The terminfo variables are defined elsewhere so it
should be safe.
Also remove an unnecesary cast in minicurses.
Hopefully this satisfies all curses variants and versions now.
|
|
Older POSIX standards also defined it as a char * parameter (not const char *)
for tparm().

This makes atleast feeds with simple ASCII work.

This fixes a compile error tested with HaikuOS 32-bit (gcc2h, based on gcc
2.95).
It also suppresses a false-positive warning of an unused forkexec function in
cppcheck.

This replaces the current J and K keybind, which was rarely useful.
Thanks to IanJ for the suggestion and feedback!

When a new URL file is used with no URL entries then NULL is passed to qsort()
and bsearch(). This is reported by clang UBsan as undefined behaviour
(debatable), but no issue in practise with many implementations. Fix it anyway.
To reproduce with clang UBsan:
Compile with clang or gcc with CFLAGS and LDFLAGS -fsanitize=undefined
touch /tmp/urls # new file which should be empty.
SFEED_URL_FILE=/tmp/urls sfeed_curses 2>/tmp/log
^D
q
cat /tmp/log
|
|
|
|
Import sfeed_curses into sfeed.
The files are based of the commit 8e151ce48b503ad0ff0e24cb1be3bc93d6fbd895
