This reverts:
3fb4140c lua/defaults: add user_data helpers
68a20e7a javascript/defaults: add user_data helpers
00510379 lua/js: fix user_data_del util function
As well as the lua/js parts of:
3ec2a098 docs: document new user-data property
user-data and its sub-properties can be set/get/observed/deleted
via the standard properties interface, so there's no need for
additional helpers specific to user-data, which only added maintenance
burden.
Previously if the raw command_native_async returned an error then the
callback function was run directly. This meant that script writers
potentially had to account for both synchronous and asynchronous logic
in the callback, which can happen even with seemingly 'safe' commands
if the mpv event queue is full.
This was at odds with the Javascript implementation of
the function, which always runs the callback asynchronously.
Now the mp.add_timeout function is used to run the callback
asynchronously on error, replicating the Javascript implementation.
This provides consistency for developers in how the callback is handled
in Lua, and increases consistency between the Lua and Javascript APIs.
When utils.get_user_path was added, the expand-path command didn't
exist. Now it does, so remove the C code, make it a trivial wrapper.
Keep this function for backward compat to not break scripts, but
technically it's not required anymore.
mpv doesn't have other dot files in its config dir, and it also
shouldn't be "invisible".
The new name ~~/init.js now replaces ~~/.init.js
While mpv usually deprecates things before outright removing them,
in this case the old (dot) name is replaced without deprecation:
- It's a bad idea to execute hidden scripts, even if at a config dir,
and we don't want to do that for the next release cycle too.
- We warn if the old (dot) name exists and the new name doesn't,
which should be reasonably visible for affected users.
- It's likely niche enough to not cause too much pain.
If for some reason both names are needed, e.g. when using also an old
mpv versions, then the old name could be symlinked to the new one, or
simply have one line: `require("~~/init")` to load the new name, while
a new mpv version will load (only) the new name without warning.
The custom init script should be considered a configuration file, and
as such it should be ignored when the user wants vanilla mpv - and now
it is ignored with --no-config.
Discovered with:
find . -type f \( -name '*.md' -o -name '*.rst' \) -exec grep -n 'http://' {} +
All real, i.e. non-example, links found were moved to https. There are
some dead links and websites with no https available which were not
converted.
The callback now gets an object argument with defer/cont functions.
Like the lua code, the behavior is that each hook event allows at
most one continue, but nothing enforces the order of continuations
if more hook events arrive before prior ones were continued - which
is possible now with the defer option, but wasn't possible before
(continuation was synchronous from the hook event handler).
Directories inside ~~/scripts/ are now loaded as scripts, so don't use
it also for modules. Now there are no default module paths.
To compensate, we now try to run ~~/.init.js right after defaults.js,
so the user may extend the js init procedure via this script, e.g. for
adding default paths to mp.module_paths .
Now that 00af718a made the lua read_options behavior much more similar
to the js behavior, the main difference was that lua does not re-read
the config file at on_update (but it does re-apply its stored content)
while js did re-read it.
Now the js on_update also does not re-read the config file and instead
applies its stored original content.
This is slightly hacky by adding an undocumented optional 4th argument
to read_options which allows overriding the config file content.
This is a bit different than the lua code: on script-opts change it
simply re-applies the conf-file and script-opts to the options object,
and if this results in any changed value at options then on_update is
called with the changelist as argument.
This allows a value to revert back to the conf-file value if the
matching script-opts key had a different value and then got deleted.
It also guarantees to call back whenever the options object is
modified, which the lua code doesn't do (e.g. if the caller changed
a value and the observer changed it back - it won't detect a change).
Due to earlier misinterpretation of the Lua docs as if mp.register_idle
registers a one-shot callback, the JS docs suggested to use setTimeout.
But the behavior and Lua docs are such that it's a repeating callback
which fires just before the script thread goes to sleep.
Implement it for JS too.
Usable for uniquely identifying mpv instances from
subprocesses, controlling mpv with AppleScript, ...
Adds a new mp_getpid() wrapper for cross-platform reasons.
This commit introduces mp.utils.file_info() for querying information
on file paths, implemented for both Lua and Javascript.
The function takes a file path as an argument and returns a Lua table /
JS object upon success. The table/object will contain the values:
mode, size, atime, mtime, ctime and the convenience booleans is_file, is_dir.
On error, the Lua side will return `nil, error` and the Javascript side
will return `undefined` (and mark the last error).
This feature utilizes the already existing cross-platform `mp_stat()`
function.
Implements JS with almost identical API to the Lua support.
Key differences from Lua:
- The global mp, mp.msg and mp.utils are always available.
- Instead of returning x, error, return x and expose mp.last_error().
- Timers are JS standard set/clear Timeout/Interval.
- Supports CommonJS modules/require.
- Added at mp.utils: getenv, read_file, write_file and few more.
- Global print and dump (expand objects) functions.
- mp.options currently not supported.
