lua/js utils.get_env_list() uses `environ' which was ANSI, thus
it broke any unicode names/values.
mpv already has an internal utf8_environ for win32, but it's used
only at the getenv(..) wrapper and not exposed in itself, and also it
has lazy initialization - on first getenv() call.
Now `environ' maps to a function which ensures initialization while
keeping it an l-value (like posix expects).
The cost of this fuglyness is that files should include osdep/io.h
(which now declares environ as extern) rather than declaring it
themselves, or else the build will break on mingw.
The VM could throw at pushnode and before mpv_free_node_contents, which
would have resulted in leaked content.
Now this case is handled without leaks.
Note: the lua code still leaks on such case, but mp_lua_PITA doesn't
have destructors like the JS autofree has, which, specifically here,
can do mpv_free_node_contents. So TODO: enhance the lua PITA code to
behave more similar to the JS autofree.
The intention is to provide a slightly nicer way to distribute scripts.
For example, you could put multiple source files into the directory, and
then import them from the actual script file (this is still
unimplemented).
At first I wanted to require a config file (because you need to know at
least which scripting backend it should use). This wouldn't have been
too hard (could have reused/abused the mpv config file parsing
mechanism, and I already had working code that was just 2 function
calls). But probably better to do this without new config files, because
it might become a pain in the distant future.
So this just probes for "main.lua", "main.js", etc., until an existing
file is found.
Another important change is that this skips all directory entries whose
name starts with ".". This automatically excludes the "." and ".."
special directories, and is probably useful to exclude random crap that
might be lying around in the directory (such as editor temporary files,
or OSX, in its usual hrmful, annoying, and idiotic modus operandi,
sharting all over any directories opened by "Finder").
Although the changelog mentions the docs, they're added only in a later
commit.
This matches lua's 11b9315b but with the lagacy field names which the
js code used previously.
Currently the property always returns an object (with dummy/last/null
field values if there are no dimensions), but the code is ready for
a future case where it might return null if there are no dimensions - at
which case it will forward the null, breaking backward compatibility for
a better API.
Lua scripting has an undocumented mp.set_osd_ass() function, which is
used by osc.lua and console.lua. Apparently, 3rd party scripts also use
this. It's probably time to make this a public API.
The Lua implementation just bypassed the libmpv API. To make it usable
by any type of client, turn it into a command, "osd-overlay".
There's already a "overlay-add". Ignore it (although the manpage admits
guiltiness). I don't really want to deal with that old command. Its main
problem is that it uses global IDs, while I'd like to avoid that scripts
mess with each others overlays (whether that is accidentally or
intentionally). Maybe "overlay-add" can eventually be merged into
"osd-overlay", but I'm too lazy to do that now.
Scripting now uses the commands. There is a helper to manage OSD
overlays. The helper is very "thin"; I only want to force script authors
to use the ID allocation, which may help with putting multiple scripts
into a single .lua file without causing conflicts (basically, avoiding
singletons within a script's environment). The old set_osd_ass() is
emulated with the new API.
The JS scripting wrapper also provides a set_osd_ass() function, which
calls internal mpv API. Comment that part (to keep it compiling), but
I'm leaving it to @avih to finish the change.
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.
