currently if the keyhandler invocation fails, for example due to it not
being present, the statusbar does not reset and stays on "getting
keyhandler input" message.
now the return value from run_key_handler() is used to determine if the
function was successful or not. and if the function failed, we call
handle_key_handler() with false which resets the statusbar.
we also no longer call redraw() within run_key_handler() and instead assign
it's return value to dirty which does a redraw if true.
rendering is a pretty expensive operation, especially when scaling with
anti-aliasing. by waiting for the image to render before setting
timeout, the actual timeout ends up being (render time + actual delay).
this pretty much fixes the slowdown entirely on all the images i've
tested. it should also improve things noticeably even in cases where
the delay between frames is shorter than how fast we can render.
although on such images, the issue may not be fixed entirely.

* specifies the function argument type in commands.h compared to leaving
it unspecified. all the functions in cmd_t must have arg_t as it's
argument.
* changes to commands.h will now trigger a rebuild - this restores old
behavior prior to 12efa0e
* cg_quit now uses it's argument as exit status
* DestroyNotify invokes cg_quit rather than calling exit directly.
* Explicitly pass EXIT_SUCCESS to cgquit in keybinding

* fix: send implicit_mod to process_bindings
this solves the edge case where someone might have `ShiftMask + A` in
their keybindings compared to a plain `A`.

* code-style: smuggle small style fix in
win_draw_bar now mimics autoreload_nop.c functions
with the exception of arrays, all other var names in config.h are in ALL
CAPS. since keyhandler_abort is an unreleased feature, it should be okay
to rename it for consistency.
though.. in the future we should be more careful about naming when
adding new vars to config.h (or the codebase in general.)
the goal here to mark functions and variables not used outside the
translation unit as static. main reason for this is cleanliness. however
as a side-effect this can help compilers optimize better as it now has
guarantee that a certain function won't be called outside of that
translation unit.
one other side-effect of this is that accessing these vars/function from
config.h is now different.
if one wants to access a static var/func from different translation unit
in config.h, he would have to create a wrapper function under the right
ifdef. for static functions one would also need to forward declare it.
here's a dummy example of accessing the function `run_key_handler` from
config.h under _MAPPINGS_CONFIG
```
static void run_key_handler(const char *, unsigned);
bool send_with_ctrl(arg_t key) {
run_key_handler(XKeysymToString(key), ControlMask);
return false;
}
```
while i was initially against this since it can be done via `xargs -0`.
the problem with this approach is that there's a limit to how many args
a command can recieve, leading to problem like this [0] when opening
large (1k~) amount of images.
there's no limit on how big stdin can be, so being able to read a
null-separated list from stdin doesn't have this problem.

this allows users to configure navigation width from config.h. it also
allows disabling the navigation function entirely by using a 0 width.
one extra functionality this adds is being able to define an absolute
width (in pixels) instead of just percentage via `NAV_IS_REL`.

with this change `-0` is turned into a more generic switch which can be
used to send NULL-separated file-list to the key-handler as well.
this also means `-0` no longer implicitly enables `-o`

Before all the predated commands where kept in an array and their
indexes were used in bindings. This meant that users couldn't add their
own functions from the config file. Now key/mouse bindings have been
changed to to store the function ptr (wrapped in a cmd_t struct to also
store the mode) directly instead.
General cleanup done in this commit:
Defined `MODE_ALL` instead of using magic number.
For example, suppose one had bindings like:
{ 0, XK_q, g_quit, None },
{ ShitMask, XK_q, {quit_err}, None }
{ ControlMask, XK_q, {quit_err, .mode=MODE_IMAGE}, None }
The existing binding `q` has been left unchanged and is defined the same
way. However, the new hypothetical binding `Shift-q` can be used to call
the custom function quit_err in any mode (default). `Ctrl-q` on the
other hand will be called only on image mode.
Closes#50
Previously, the value of imgcursor was determined by where a pointer
binding was set to a ci_cursor_navigate. If it was then the pointer
would change to left/right arrows depending on the position relative to
the window. Now the user has full control of over it which also allows
them to preserve the behavior in case they wrap the function.

Currently when running the key-handler the statusbar shows a
"Running key-handler..." message, but there's no indication of the prefix key
being pressed.
There's a slight functional benefit of this patch in the sense
that users can visually tell if the key-handler is listening on input or if the
key-handler has been aborted or not.
ten_ms needed to be a global but after the following commit
3724d3fc17 this no longer holds true.
it can simply be local to run, as it's not used anywhere else.
Previous the code only allowed ShiftMask,ControlMask or Mod1Mask to be
used in keybindings and the presence of any others modifiers would be
ignored. Most problems generally allow certain modifiers to be be
ignored but not most and certainly don't allow Super-A to be treated
like A.
Now users can use any modifiers they want in keybindings and can also
ignore any modifiers they want. By default only ModMask2 (commonly
numlock is ignored)

If the user closed our window, the program won't automatically be die.
It may look dead as there would be no graphical indication that it was
running, but it still would be using/wasting the same resources.
Now the program will abruptly exit when its window is killed.
Fixes#276
Instead of rendering the entire filename at once, Xft will let us do it
character by character. This will allow sxiv to query fontconfig for
a font that can provide any missing codepoints, if needed.
A known issue of this patch is that the "..." dots rendering will not
work properly for very long multibyte filenames. That is because we
cannot easily predict the final width of the rendered filename before
drawing it. I couldn't figure out a clean way to deal with this, so I
ended up just truncating the offending filenames.
None of the mouse mappings uses a keyboard modifier, making it possible to
access the most basic features by only using the mouse.
Next/previous image with left button depending on cursor position, middle
button for dragging, right button for switching to thumnail mode and wheel for
zooming.
Users can keep the old behaviour by simply not adapting the changes to the
buttons array in config.def.h to their config.h file.
mv(1) inside the same filesystem was not detected.
Supporting this case made it necessary to always watch the directory. Turns out
the logic and state keeping between arl_setup() and arl_handle() is easier,
when using different watch descriptors for the file and the directory and not
using a oneshot descriptor for the file.
Requiring an absolute canonical path for arl_setup() simplifies dir and base
name splitting. No need for dirname(3) and basename(3) anymore.
Make the header only contain the public interface and nothing from the
implementation. All functions get a handle to their self object, like the img_
and tns_ and win_ functions. All necessary data (file path) is also passed as
an argument, so that no extern redeclarations are needed.
Make arl_setup_dir() private, it's not called outside the module.
Make arl_handle() return true if the file has changed, so that the reloading of
the file can be done by the caller.
Misbehaving command lines in the key-handler that rewrite the given files and
thus replace symbolic links instead of their targets shall call realpath(1).
Fixes issue #205 and reverts commit 92e3b578.
- Functions warn() and die() replaced by GNU-like error(3) function
- Register cleanup() with atexit(3)
- Functions called by cleanup() are marked with CLEANUP and are not allowed to
call exit(3)
- Only load the thumbnails that are currently visible in the window
- Unload thumbnails that are leaving the visible area
- Much less memory needed, but scrolling is now slower
- This also unintentionally fixes issue #86

- Buffer for window content is bigger than the window, minimizes artifacts
when window is resized
- Back to using XSetWindowBackgroundPixmap() instead of XCopyArea(),
no need to handle exposure events; X server can show gray background directly
after resize event before sxiv redraws the window contents
