This adds script messages to select playlist entries, tracks, chapters,
subtitle lines, bindings and properties using the newly introduced
mp.input.select().
This fully closes#13964.
When you select an item, due to the submit handler being called
asynchronously, the default item list is redrawn before the console
closes, which is jarring. Fix this by always closing the console as soon
as enter is pressed, as keeping it open is unlikely to be useful with a
fuzzy selector (unlike with input.get() where it can be used e.g. to
implement a Lua REPL). If desired we can later add a close_on_submit
flag defaulting to true.
Also fix a crash when pressing enter without any match.
With mp.input.select() these keybindings were both scrolling and moving
the cursor because of how the condition was written and
handle_pgup()/handle_pgdown() not returning a truthy value.
selected_match can become 0 when pressing certain scrolling
keybindings without any match, and
for i = first_match_to_print, last_match_to_print do
in populate_log_with_matches() runs from 0 to 0 and accessing
matches[0].text crashes console.lua. Return early when it is 0.
Avoid messing up the max_log_lines calculation when mp.input.select() is
called with very long items.
This doesn't work with Japanese characters because they are bigger.
I misunderstood CogentRedTester's review in
https://github.com/mpv-player/mpv/pull/10282#discussion_r1428972352 as
referring to the cursor_position in mp.input's arguments instead of the
one received by the closed callback.
The cursor_position passed to input.get doesn't need to be converted to
a number because it was already JSON, while the cursor_position received
by the closed callback is currently a string, and we need to pass JSON
in input-event script messages to keep it as an integer to work around
mpv converting integer script message arguments to string.
This is more noticeable after implementing mp.input.select(): its submit
argument currently receives the selected index as a string, and this
makes Lua error if you use it as an index of a numerical table, e.g.:
submit = function (id)
mp.set_property(property, tracks[tonumber(id)].selected and "no"
or tracks[tonumber(id)].id)
...
end,
This commit avoids having to call tonumber(id).
This allows more completions than patterns:
Both single and double quotes are recognized.
Quotes around the first token are recognized.
Command prefixes are recognized.
Choice options are completed after change-list/vf/af add/append/pre/set.
File paths are completed after set/cycle-values/change-list with options
that expect files, including cycling between paths with spaces, e.g.
cycle-values glsl-shaders 'foo bar' 'baz qux'.
File paths are completed in the fourth argument of dump-cache.
Items that have been set are completed after change-list remove.
This is unused since 4e013afd37 because the mpv logo and the "Drop files
or URLs to play here." message are shown instead of the OSC controls. It
has the adverse affect of making the OSC twice as big when playing
videos with --lavfi-complex, because that makes the video property which
osc.lua checks unavailable.
This allows scripts to make the user choose from a list of entries by
typing part of their text and/or by navigating them with keybindings,
like dmenu or fzf.
Closes#13964.
This change displays the scaled position and size of the image before
cropping to the target rectangle. In simple terms, it shows how much
margin has been added to the image or how much of the image has been
cropped.
Note that target resolution is displayed after crop as in fact all other
pixels are discarded anyway.
This lets you press / in page 4 of the stats and type a keybinding or
part of its command to filter it by using mp.input.
This works badly without a VO because both stats.lua and console.lua use
show-text and only one can be displayed at a time, but it's still better
than not having the search available at all.
Avoid having to configure both the OSD and the stats script opts when
you change the OSD options, in particular avoid having to convert colors
to BGR.
Also document the shadow options.
font_size, border_size and shadow offset defaults are kept because the
same values look much bigger in the stats than in the corresponding OSD
options.
osd-back-color is now respected without extra checks until you
explicitly set a shadow_color.
Showing media titles in the playlist is pointless when sources are ill
tagged and media titles contain only garbage. Being able to opt for
file names at least gives us a choice in such cases.
Turns out that adding more medatata like HDR10+ and Dolby Vision would
produce a lot of duplication and it is better to centralize it around
the track-list property.

Escape all messages in osc.lua, because other than the title they
weren't being escaped at all. If for example you did mpv foo.mp4
'{\fs50}bar.mp4' and script-message osc-playlist, it would just render
the second entry as bar.mp4 in big text.
The title was escaped partially, now the escaping is complete because:
- It escapes \. Backslashes at the end of the title are escaped instead
of being stripped, and \n, \N and \h are now printed verbatim. In
particular, "\\n" is no longer converted to space and is printed
verbatim instead which is more correct.
- Newlines ("\n", not the "\\n" escape sequence) are converted to spaces
instead of rendering them and messing up the text positioning within
the OSC.
- Spaces at the start are preserved.
Fixes#11209, fixes#11275.
This adds a command to escape ASS tags to remove code duplication
between sub/osd_libass.c, console.lua, osc.lua, stats.lua and any user
script that calls mp.create_osd_overlay().
A command is used instead of scripting functions so that all clients can
use this and not just use Lua and JS ones.
osd_mangle_ass() also interprets osd-sym-cc and osd-ass-cc/{0,1}, but
since they use invalid UTF-8 characters there is no risk of escape-ass
users using them by accident, like with any OSD message.
Always replacing \n with \\N in mangle_ass() even when it is not called
by escape-ass doesn't seem to cause any issue, but I made it conditional
anyway to avoid changing how all OSD messages are treated unnecessarily.
The terminal output was static in size with no way of automatically
adjusting it to the current terminal size.
The new term-size property makes truly automatic adjustment possible.
The scroll hint on page 4 had baked in ass tags, which shouldn't be
there in the terminal. Also the scroll hint on page 0 was missing.
Refactor scroll hint generation into a function and use that for
pages 2, 4 and 0.
The terminal is assumed to be 80x24 in size, the new options
`term_width_limit` and `term_height_limit` can be used to overwrite
that.
Lines longer then the terminal width cause problems with scrolling
pages and need to be shortened.
The algorithm used for shortening can deal with tabs and escape
sequences, has rudimentary support for UTF-8 and runs in O(n).
avih helped in the creation of the term_ellipsis() function and split()
is also from him.
Pages 2 and 0 had their own scroll implementations, which worked fine
for ass, but didn't work well in the terminal.
Now they both use the same scroll function as page 4.
That scroll function requires each output line to be one entry
in the table. Page 0 did not adhere to that new requirement, instead
it generated two table entries for a single output line when a graph
is shown. To fulfill that requirement the generated graph now gets
directly appended to the same table entry that's used for the rest
of the line.
This scrolling implementation will be used for other pages in future
commits.
The comment said it takes up 20 lines of the terminal, but in reality
it was 22 lines.
When --osd-blur is set to a nonzero value, the graphs also become
blurry. This is because they are rendered by the osd-overlay command
with the "OSD" style which has OSD blur applied, and are treated no
differently from texts. Fix this by using the "Default" style for
these graphs which uses the default OSD options.
Move common_prefix_length() and related functions before the first call
to common_prefix_length(). It works now because it's global but if we
ever make all functions local for consistency it will stop working.
