Simple media logger Lua script for mpv

mpvhistory.lua

-- Not my code: originally from https://redd.it/3t6s7k (author deleted; failed to ask for permission).
-- Only tested on Windows. Date is set to dd/mmm/yy and time to machine-wide format.
-- Save as "mpvhistory.lua" in your mpv scripts dir. Log will be saved to mpv default config directory.
-- Make sure to leave a comment if you make any improvements/changes to the script!

local HISTFILE = (os.getenv('APPDATA') or os.getenv('HOME')..'/.config')..'/mpv/mpvhistory.log';

mp.register_event('file-loaded', function()
    local title, logfile;

    title = mp.get_property('media-title');  
    title = (title == mp.get_property('filename') and '' or ('(%s)'):format(title));

    logfile = io.open(HISTFILE, 'a+');
    logfile:write(('[%s] %s %s\n'):format(os.date('%d/%b/%y %X'), mp.get_property('path'), title));    
    logfile:close();
end)

great script, I'd suggest using double quotes instead of single quotes IMHO

Great script, I modified it and intergrated it to a project that scrolls mpv title in the panel in xfce desktop environment.

@garoto Hi, I have a little question if you have time. How to modify this lua so that each entry starts on a new line instead of continuing the previous line or insert an empty line between entries to make the history look better and clearer.

@jimmy-1000 Not sure what you mean, but a LF char is already inserted at the end of every line, see line #15: logfile:write(('[%s] %s %s\n') See the "\n" there? Yeah, that's the Lua newline escaped char. Or maybe the log viewer you're using doesn't recognize a single LF as a newline delimiter, like Win7 notepad.exe perhaps?

You are right in everything you say, what a shame 🙈

No worries my dude, but in anycase, if you want to have a file that has CRLF as line endings, just add a \r before the "\n" at line #15 like I mentioned in my comment, so it'd be like: logfile:write(('[%s] %s %s\r\n')

Thanks! This greatly improves the look with notepad.
