2022-08-16code-style: don't indent switch cases (#358)explosion-mental
The suckless coding style [^0] and the linux coding style [^1] both recommends not indenting switch cases. And it helps out people with lower resolution monitors.

2022-08-16code-style: various cleanups (#356)NRK
* run_key_handler: make the logic easier to follow * remove timeout_t the typedef is not needed. inline the declaration similar to the other static structs. * simplify estrdup reuse emalloc, instead of calling malloc and null-checking. * win_clear: initialize `e` right away * process_bindings: explicitly check against NULL most pointer checks in the codebase do explicit check. * use a named constant instead of magic number also changes the padding from 3 to 4 bytes according to [0]. but i couldn't find any situtation where this mattered, so perhaps the current padding is enough. but doesn't hurt adding one more byte.

2022-07-30autoreload: simplify and cleanup (#342)NRK
the current code is quite hacky and complex as it mixes multiple pointers. all of this complexity is unnecessary. drop it by introducing an explicit scratch buffer instead of implicitly abusing `arl->filename` as one. this also reduces some unnecessary allocation overhead. additionally, the argument to arl_setup must be the result of `realpath(3)` (as commented in `nsxiv.h`). instead of commenting it, assert it. and lastly, rename `arl_setup` to `arl_add` since it's not doing any "setup" but rather *adding* a file to watch.

2022-07-26fix: stale statusbar when started in thumbnail mode (#341)NRK
this was one of the cases which got missed in 591be8c, if someone starts with `-t` the statusbar will remain at "Loading ...". Once we're done loading all the thumbnail, make sure to open_info() so that `thumb-info` gets called.

2022-07-15fix: -Wsign-compare warnings (#336)NRK
mixing signed and unsigned types in comparison can end up having unintended results. for example: if (-1 < 1U) printf("true\n"); else printf("false\n"); previously we silenced these warnings, instead just fix them properly via necessary casting, and in cases where the value cannot be negative (e.g width/height members) make them unsigned.

2022-06-02code-style: simplify window title related codeNRK
instead of dancing around with some `init` parameter, directly give `win_set_title()` what it needs. `get_win_title()` now also does *just* what the name says. this simplifies things quite a bit and the functions now do what their name implies more closely instead of doing some `init` dance internally.
2022-06-02reduce calls to win-titleNRK
rather than calling the script unconditionally per redraw, we now have a `title_dirty` flag and keep track of when any of the relavent information changes. Co-authored-by: Arthur Williams <taaparthur@gmail.com> Partially fixes: https://github.com/nsxiv/nsxiv/issues/258
2022-05-28fix: broken slideshow if redraw takes too long (#282)N-R-K
currently the way check_timeout() is implemented, animate has higher priority than slideshow. so if doing a redraw takes longer than the frame delay of the animated image then it's going to continuously keep animating and never reliably get to slideshow. this issue can occur if the animated image has too fast of a delay or if nsxiv is being run on a slow system where doing redraw takes too long. the issue can be emulated by artificially slowing down img_render by sticking a sleep in there. diff --git a/main.c b/main.c index 5dc52d4..0580011 100644 --- a/main.c +++ b/main.c @@ -441,6 +441,7 @@ void redraw(void) if (mode == MODE_IMAGE) { img_render(&img); + nanosleep(&(struct timespec){0, 62000000}, NULL); /* 62ms */ if (img.ss.on) { t = img.ss.delay * 100; if (img.multi.cnt > 0 && img.multi.animate) make it so that slideshow has higher priority than animate to fix the issue.

2022-05-19fix: broken statusbar after key-handler cancellationNRK
to reproduce: 1. have an image-info script 2. invoke the key-handler 3. cancle invocation by pressing `escape` at this point, the statusbar ends up being empty. the regression seems to be caused by 6922d5d (changing select to poll), unsure why that is. in any case, this simplifies read_info quite a bit and solves the regression as well. in short: * read straight into the statusbar buffer * if read succeeds, make sure buffer is null terminated and replace any newline with space * close the script
2022-05-19fix: don't override statusbar if info script doesn't existNRK
this happens when the keyhandler is invoked while viewing an animated image. if {image,thumb}-info scripts exists, everything works as expected. but if they don't, then update_info will override the statusbar.

2022-05-12check_timeouts: avoid unnecessary conversions (#273)N-R-K
before we were using select, which expected `struct timeval` as arg. so we needed to do ms -> timeval conversions. but now since we're using poll, which accepts milisec as arg, there's no need to do ms -> timeval -> ms. instead have check_timeouts directly return ms.

2022-04-28replace select() with poll() (#270)N-R-K
usage of select (3) in modern programs is typically discouraged. this simply replaces the select call with poll (3) instead. and since poll conveniently ignores negative fds, this also reduces needs for some special casing. this also handles error if they occur, while old implementation didn't. other than the error handling, no change in functionality should occur.

2022-01-10make thumbnail bindings configureable via config.h (#167)N-R-K
this allows for configuring thumbnail mode mouse bindings similar to image mode bindings. however we can't put the thumbnails bindings into the existing buttons[] array due to fallthrough. For example M3 would switch mode and then end up selecting an image. which is why thumbnail bindings have been put into it's own array `buttons_tns[]` and `buttons[]` has been renamed to `buttons_img[]` for consistency. Closes: https://github.com/nsxiv/nsxiv/issues/131
2022-01-06fix -Wshadow related warningsNRK
fixes all -Wshadow related warnings (on gcc). this would allow us to use `-Wshadow` in github workflow (https://github.com/nsxiv/nsxiv/pull/195). i've thought about adding `-Wshadow` to our Makefile as well, but decided against it to keep the Makefile CFLAGS barebore/minimal.
2022-01-03fix: reset statusbar after failed keyhandler (#191)N-R-K
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.
2022-01-02fix: animation slowdown when zoomed in (#200)N-R-K
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.

2021-11-24rename: keyhandler_abort -> KEYHANDLER_ABORT (#172)N-R-K
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.)
2021-11-20mark functions and vars as static (#146)N-R-K
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; } ```

2021-11-19apply -0 to stdin/-i as wellNRK
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.

2021-10-13Add ability to bind arbitrary functions.Arthur Williams
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
2021-10-13Make imgcursor a config variable.Arthur Williams
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.
