Very primitive and dumb, but fulfils its purpose for the next commits.
I chose this specific implementation because it has the lowest footprint
in command.c, without resorting to crazy hacks such as sending messages
between scripts (which would be hard to coordinate especially on
startup).
Later calls to mp.add_key_binding() should take priority over previous
calls with the same key. Until now, the order was random (due to using
table pairs() iteration order).
Do this by simply sorting by a counter that is never reset. Since
input.c also gives later bindings priority, this works out.
Calling mp.remove_key_binding() on a newer binding makes an older still
existing binding with the same key active again. New bindings override
older ones, but do not overwrite them. I think these are good semantics
for most use cases.
(Note that the Lua code cannot determine whether two bindings use the
same key. Keys are strings, and two different strings could refer to the
same key. The code does not have access to input.c's key name
normalization, so it cannot compare them.)
Commit 311cc5b6 added the ability use flags while omitting name, but
broke the case where both name and flags are omitted.
Now omitting either name or flags or both works as documented.
add_key_binding() makes the name argument optional (in weird Lua
fashion), which did not work if there were additional arguments. So
there is no way to avoid specifying a name while passing a rp argument.
Fix this, declare this way of skipping the argument as deprecated, and
allow passing name=nil as the preferred way to skip the name argument.
Particularly for "any_unicode" mappings, so they don't have to
special-case keys like '#' and ' ', which are normally mapped to
symbolic names for input.conf reasons. (Though admittedly, this is a
pretty minor thing, since API users could map these manually.)
Manual changes done:
* Merged the interface-changes under the already master'd changes.
* Moved the hwdec-related option changes to video/decode/vd_lavc.c.
Idle handlers used to not be executed when timers were active
Now they are executed:
* After all expired timers have been executed
* After all events have been processed (same as when there are no timers)
The "run" command is old. I'm not sure why the separate Lua
implementation was added. But maybe it as because the "run" command used
to be limited to a small number of arguments. This limit has been
removed a while ago. In any case, the old implementation is not needed
anymore.
We keep mp.subprocess() with roughly the same semantics for
compatibility with scripts (including the internal ytdl script).
Seems to work with rhe ytdl wrapper. Not tested further.
As it turns out, there are multiple libmpv users who saw a need to
use the hook API. The API is kind of shitty and was never meant to be
actually public (it was mostly a hack for the ytdl script).
Introduce a proper API and deprecate the old one. The old one will
probably continue to work for a few releases, but will be removed
eventually.
There are some slight changes to the old API, but if a user followed
the manual properly, it won't break.
Mostly untested. Appears to work with ytdl_hook.
As threatened by the API changes document.
This commit also removes or stubs equivalent calls in IPC and Lua
scripting.
The stubs are left to maintain ABI compatibility. The semantics of the
API functions have been close enough to doing nothing that this probably
won't even break existing API users. Probably.
Instead of rechecking the timers every time after an event is read, do
it only once the event queue is empty. This is probably slightly more
efficient, and facilitates the next commit.
Old-style commands using _ as separator (e.g. show_progress) were still
used in some places, including documentation and configuration files.
This commit updates all such instances to the new style (show-progress)
so that commands are easier to find in the manual.
This changes behavior somewhat. The old behavior can be restored by
running "mp.use_suspend=true". It was originally introduced for the OSC,
but I can't reproduce whatever misbehavior I was seeing.
(See mp.suspend()/resume() for explanations what the suspend mechanism
does.)
Removes some more internal API calls from the Lua scripting backend.
Which is good, because ideally the scripting backend would use libmpv
functions only.
One awkwardness is that mouse sections are still not supported by the
public commands (and probably will never), so flags like allow-hide-
cursor make no sense to an outside user.
Also, the way flags are passed to the Lua function changes. But that's
ok, because they're only undocumented internal functions, and not
supposed to be used by script users. osc.lua only does due to historical
reasons.
Wnile it seems quite logical to me that commands use _ as word
separator, while properties use -, I can't really explain the
difference, and it tends to confuse users as well. So always
prefer - as separator for everything.
Using _ still works, and will probably forever. Not doing so would
probably create too much chaos and confusion.
The global unpack function got moved to table.unpack in Lua 5.2, and
it's only available as the global if 5.2 is built with compatibility
enabled (the default). Lua 5.3 does not build with 5.1 compatibility by
default.
Fixes#1648.
- --lua and --lua-opts change to --script and --script-opts
- 'lua' default script dirs change to 'scripts'
- DOCS updated
- 'lua-settings' dir was _not_ modified
The old lua-based names/dirs still work, but display a warning.

Yep, Lua is so crappy that the stdlib doesn't provide anything like
this.
Repurposes the undocumented mp.format_table() function and moves it to
mp.utils.
Simpler, and leaves the decision to repeat or not fully to the script
(instead of requiring the user to care about it when remapping a script
binding).
Otherwise, mouse button bindings added by mp.add_key_binding() would be
ignored.
It's possible that this "breaks" some older scripts using undocumented
Lua script functions, but it should be safe otherwise.
Fixes#1283.
Now a negative timeout mean an infinite timeout. This is similar to the
poll() system call. Apparently this is more intuitive and less confusing
than specifying a "very high" value as timeout if you want to wait
forever.
For callers that never pass negative timeouts, nothing changes.
Although this is something really basic, Lua's standard library doesn't
provide anything like this. Probably because there are too many ways to
do it right or wrong.
This code tries to be really careful when dealing with mixed
arrays/maps, e.g. when a table has integer keys starting from 1, making
it look like an array, but then also has other keys.
Now they can be paused and resumed.
Since pausing and disabling the timer is essentially the same underlying
operation, we also just provide one method for it.
mp.cancel_timer probably still works, but I'm considering this
deprecated, and it's removed from the manpage. (We didn't have a release
with this function yet, so no formal deprecation.)
