2021-12-08random_playlist.lua make index more sparseWilliam Wilgus1-38/+87
The name of the game here is to load the database file without taking over the audio buffer. 5mb database file will now successfully load added an option to save playlist directly to disk and bypass the rb builtin function completely however if you choose play the playlist will be loaded back from the disk into the inram dynamic playlist Change-Id: I43e76f63379721f36ed082c0ad47a6f2539fb15f

2021-12-05random_playlist.lua bugfixWilliam Wilgus1-1/+2

uses the database to create random playlists of specified size with the advanced GUI you can.. set the number of songs (up to max playlist buffer) set the number of tracks before a repeat is allowed play the tracks when finished -- fix a parsing bug where first and last entry in database were corrupted -- Incremental loading for very large databases, allows decent speed and lower ram usage Change-Id: Ia95469b6a04625b621129ec61e5db4b2b00adc5e

2020-10-05lua add better memory statsWilliam Wilgus1-0/+32
lua gives you a memory used number that only reflects the current allocations if fact it doesn't even give you a way to get the amount of ram free rb.mem_stats() seeks to fill this gap by marking the memory allocated for lua with a sentinel value which can later be checked to get a high water mark of the ram used by lua and a pretty good idea of how much ram is available Also includes an example script usage: used, allocd, free = rb.mem_stats() Change-Id: Ia282869f989848324d7d88c7df4827fdbce4fb4e

2020-10-03lua Add scrollable stack traceback WIPWilliam Wilgus1-0/+1
lua currently splashes a stack traceback on error for deep tracebacks and especially on devices with smaller screens this leaves out a lot of vital information in the past I have resorted to splitting the traceback string or even saving the return to a file This patch provides a scrollable buffer with rudimentary text reflow to allow you to read the whole traceback string Upon traceback if you press nothing the screen will display for 5 seconds If you press OK or CANCEL it will quit immediately PREV/NEXT scrolls the list on button press timeout is disabled lua now provides rb.splash_scroller(timeout, str) example script provided too Change-Id: Idbc8ce0c514196f0fae48c43aeaea8b60d6da1a5

2020-09-27lua playback exampleWilliam Wilgus1-0/+459
cool little lua based audio player creates dynamic playlist of 10 mp3s found on device if no music loaded I had to limit the depth of search to 3 levels due to the recursive nature of the current dirbrowser functions this could be rectified with a bit more code fixed a bug in print.lua that kept scrolling text even after screen clear Change-Id: Ifd285332df41a409ecaeb1ea447ad15537b5d04c
