Losing tab complete and text macros, for now.
This new implementation works on an instance of a struct and does
not interact with the rest of catgirl, making it possible to copy
into another project. Unlike existing line editing libraries, this
one is entirely abstract and can be rendered externally.
My goal with this library is to be able to implement vi mode. Since
it operates on struct instances rather than globals, it might also
be possible to give catgirl separate line editing buffers for each
window, which would be a nice UX improvement.
Do some extra work by adding the portion before the cursor to the
input window twice, but simplify the interaction with the split
point. This fixes the awkward behaviour when moving the cursor
across colour codes where the code would be partially interpreted
up to the cursor.
Strip formatting when calculating the timestamp width to avoid
moving a bunch of code around. Use styleAdd (now with an initial
style parameter) to show timestamps.
This allows changing the style of the timestamps from the default
gray using literal IRC formatting codes in the string. Not ideal,
but no new options needed.

On OpenBSD it's in <fcntl.h>, and it gets declared anyway on FreeBSD
and macOS. Curiously, on GNU/Linux, LOCK_* are defined, but flock(2)
isn't declared.
Messages don't really need to be hidden from <network> and I think
it could be confusing. Debug messages are all Cold so everything
would be hidden, and I want to keep them that way so that <debug>
doesn't clutter the status line needlessly.
Silencing all windows with `M-+' (across multiple catgirl instances)
can be cumbersome, so provide an option to hide events, JOIN/PART noise,
etc. by default (each window's threshold will persist across load/save
cycles, i.e. when using the `-s/save' option).
Started out as `-v | visibility = threshold' to set a specific level,
the idea of a simpler toggle comes from june, who also squashed other
bugs (as usual).
caph_stream_rights(3) doesn't exist before FreeBSD 13.0 and there's
no good reason to create that dependency. I still run servers on
FreeBSD 12.
This is a partial revert of cbc9545cb3.
Otherwise "/exec sh </dev/tty" takes over and catgirl must effectively
be killed to stop the madness; with this diff:
catgirl input| /exec sh </dev/tty
catgirl output| /bin/sh: cannot open /dev/tty: Device not configured
catgirl output| Process exits with status 1
Do the same for `-C/Copy', `-N/notify' and `-O/open' alike.
Avoids another small TOCTOU. Rewind before loading since "a+" sets
the file position at the end. Remove unnecessary fseek after
truncation, since "a+" always writes at the end of the file.
Opening the same file *path* twice is a TOCTOU, although not a critical
one: worst case we load from one file and save to another - the impact
depends on how and when catgirl is started the next anyway.
More importantly, keeping the file handle open at runtime allows us to
drop all filesystem related promises for `-s/save' on OpenBSD.
uiLoad() now opens "r+", meaning "Open for reading and writing." up
front so uiSave() can write to it. In the case of a nonexistent save
file, it now opens with "w" meaning "Open for writing. The file is
created if it does not exist.", i.e. the same write/create semantics as
"w" except uiLoad() no longer truncates. existing files.
uiSave() now truncates the save file to avoid appending in general.
When waddnstr is called with a string that would extend past the
end of the window, the string is truncated, the cursor remains at
the last column, and ERR is returned. If this error is ignored and
the loop continues, the next call to waddnstr overwrites the character
at this column, resulting in a slight visual artifact. When the
window is too small to fit the full status line, it is effectively
truncated by one space on the right, since the string shown for
each channel begins with a space. Additionally, if the last window
is the current window, the space is shown with a colored background.
To fix this, when waddnstr returns ERR, exit the loop in styleAdd()
early return -1 to propogate this error down to the caller.
Apparently these are common. There's no terminfo for these, so
manually define the xterm sequences.
There's no documentation in the manual for the "intuitive" keys...
I'm not sure if that should continue to be the case or not.
A_BLINK has probably always existed, but there's no good reason to
ever use it, so make it do italics instead. Normally all attributes
are set by a single set_attributes string if it's set, so clear it
to force ncurses to use the reassigned enter_blink_mode string. If
the terminal has no enter_italics_mode string, then nothing will
happen.
This makes setting multiple attributes a bit less efficient, but I
don't think it's likely to make much of a difference since using
multiple attributes at once is so uncommon.
OpenBSD's xterm doesn't have bracketed paste mode, and it would be
nice to still be able to paste in several lines and collapse them
with M-q, provided one remembers to type C-z p first...
A little annoying to make it a "chord" like this, but C-v is already
used for scrolling, following Emacs-style key bindings (in order
to have a way to scroll without using "special" keys like the arrows
and page up/down), and C-z is at least already in the business of
inserting control characters. This makes it possible to manually
enter some things that are otherwise only possible with /exec printf.
With the early return, mainUpdate doesn't get called in cases where
other functions expect windowShow to call it, such as when closing
or moving windows.
I don't know why I ruled this out originally, it's more visually
pleasing to me now especially that threshold is likely to remain
set at "+" for a long time.
Finally! Changing the message visibility threshold doesn't totally
screw up scroll position. Neither do horizontal resizes, but vertical
resizes drift because the value of windowTop() changes before and
after...
The scroll position is anchored to the top of the window. It's
arbitrary whether to anchor the top or the bottom, but other scrolling
commands like M-p and C-r are anchored to the top, so this is
consistent.
