Semantics changes are the same as at 548ef078 .
Also, the previous C implementation returnd a string for the `stdout`
value, but stdout of the subprocess command is MPV_FORMAT_BYTE_ARRAY
which js previously didn't support, so support it too (at pushnode)
by returning it as a string - the same as the lua code does.
There were some cases where a js number (double) was blindly casted to
int or uint64, but that can be undefined behavior (out of range to int)
or wrong (negative to uint).
Now the code throws a js error if the value is out of range.
Additionally, commit ec625266 added these checks for the new hooks API,
but incorrectly tested int64 range rather than uint64. Fix this 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.
Also implicitly fixes memory leak when mp.set_property_native was used,
because the cleanup did not expect more allocations from the accidental
use of mpv_get_property.
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.
