2019-07-28Lua Add Emergency Garbage CollectorWilliam Wilgus
Derivative of work by RobertGabrielJakabosky http://lua-users.org/wiki/EmergencyGarbageCollector I've only implemented the not enough memory part and expanded this idea to adding a mechanism to signal the OOM condition of the plugin buffer which allows us to only grab the playback buffer after garbage collection fails (SO THE MUSIC KEEPS PLAYING AS LONG AS POSSIBLE) Change-Id: I684fb98b540ffc01f7ba324ab5b761ceb59b9f9b

2019-07-19lua events from rockboxWilliam Wilgus
This library allows events to be subscribed / recieved within a lua script most events in rb are synchronous so flags are set and later checked by a secondary thread to make them (semi?) asynchronous. There are a few caveats to be aware of: FIRST, The main lua state is halted till the lua callback(s) are finished Yielding will not return control to your script from within a callback Also, subsequent callbacks may be delayed by the code in your lua callback SECOND, You must store the value returned from the event_register function you might get away with it for a bit but gc will destroy your callback eventually if you do not store the event THIRD, You only get one cb per event type ["action", "button", "custom", "playback", "timer"] (Re-registration of an event overwrites the previous one) Usage: possible events =["action", "button", "custom", "playback", "timer"] local evX = rockev.register("event", cb_function, [timeout / flags]) cb_function([id] [, data]) ... end rockev.suspend(["event"/nil][true/false]) passing nil affects all events stops event from executing, any but the last event before re-enabling will be lost, passing false, unregistering or re-registering an event will clear the suspend rockev.trigger("event", [true/false], [id]) sets an event to triggered, NOTE!, CUSTOM_EVENT must be unset manually id is only passed to callback by custom and playback events rockev.unregister(evX) Use unregister(evX) to remove an event Unregistering is not necessary before script end, it will be cleaned up on script exit Change-Id: Iea12a5cc0c0295b955dcc1cdf2eec835ca7e354d

2019-07-18lua move constants out of binary imageWilliam Wilgus
Rockbox constants are auto generated by a perl script like the majority of the plugin functions. Constants are contained in rb_defines.lua, if the file exists it is auto loaded by the lua state for backwards compatibility Frees ~1k Change-Id: I237700576c748f468249e501c839d89effca3f39

2019-07-11lua late bound cfunction tablesWilliam Wilgus
We have quite a bit of ram tied up in lua with our c libraries I was searching for a way to free up some of this when I came across read only tables in e-lua but that involved a lot of patching through the source Instead I came up with this.. it frees about 15k ram without much slowdown in code execution since after a function gets called it is automatically added to the table If you have a performance issue you can call the bind method to bind a specific function or the whole table in one shot for instance rb table rb("lcd_clear") -- binds/returns function rb.lcd_clear() rb(nil) -- binds every function in rb table + removes latebind metatable .. -- added pairs and ipairs code from lua 5.2 -- cleaned up code + made more seamless existing fields are now saved rather than overwritten when table is bound Change-Id: I1c20e76b736c032dedc727d2e58928641e40191d
2019-07-11lua inbinary stringsWilliam Wilgus

2018-12-24Fix lua helpers -- supress line markers in preproc source generation scriptsWilliam Wilgus
In newer builds line markers prevent lua helper scripts from grabbing some inputs especially _bool This patch adds the -P switch Inhibit generation of linemarkers in the output from the preprocessor. This might be useful when running the preprocessor on something that is not C code, and will be sent to a program which might be confused by the linemarkers.

2018-11-01Lua Fix utf8encode, remove utf16 functionsWilliam Wilgus
The auto generated utf8/16 encode/decode functions did not work. Upon implementing them correctly I found that lua handles the utf-8 form properly but I could not get utf-16 to work without crashing maybe someone can come along later and implement utf-16 safe string functions but for now utf-16 is removed.

2018-10-29Lua replace fscanfWilliam Wilgus
Rocklua was using the full fscanf implementation to simply read %ld for the file:read("*n") function wasting 1k on unneeded/unused functionality Instead, I've implemented a filetol function to duplicate it without the extra overhead using strtol which as an added bonus ERANGE errors now resolve to LONG_MIN and LONGMAX instead of integer overflow filetol() reads long int from an open file, skips preceding whitespaces returns -1 if error, 1 on success. *num set to LONG_MAX or LONG_MIN on overflow. If number of digits is > than LUAI_MAXNUMBER2STR filepointer will continue till the next non digit but buffer will stop being filled with characters. Preceding zero is ignored.

2018-10-30Lua expand multiple screen supportWilliam Wilgus
Some of the lcd functions had support for multiple screens but this wasn't very safe since the screen number wasn't bounded within the screens[] array This adds support for all the lcd functions along with checking that screen# is bounded properly, adds around 600 bytes to devices with a remote screen devices without a remote screen lock to SCREEN_MAIN Change-Id: I618bbc7b3919c7b0ff375fb2d71949d7cab43c87
2018-10-30Lua rliimage optimize rli_marshal, rli_copy, lcd_xxx_bitmapWilliam Wilgus
rli_marshal and rli_copy allow the use of a custom lua function instead of the built-ins, this custom function can signal to stop before the whole image is iterated. Originally it was checking for a return of 0 which was additional overhead for the built-in functions (which never stop early) as well. Now custom_transform sets the x & y deltas to 0 to indicate early exit removing an extra 'if' per cycle and return from all of the rli_transform functions The lcd_xxx_bitmap functions all require x, y, w, h, screen these calls have been consolidated into a single function get_bmp_bounds() Change-Id: I88de3149c58d1bfb40e9d1a91341fb86cbd63b51

2018-10-25lua consolidate playlist_ functionsWilliam Wilgus
The way to call the playlist functions has changed rb.playlist("option", var) rb.playlist_add(filename) = becomes rb.playlist("add", filename) added playlist.lua to the includes for conversion to old functions if your script is broken by this change you simply add `require("playlist")` to the top for the old functionality added rb.playlist_tracks(dir, filename) to playlist.lua this will allow you to add all tracks in a playlist.m3u8 to a lua table Change-Id: I87fcc56be365d8495d214f069331b6ddbfbef1db
2018-10-24lua add audio_play consolidate audio_ functionsWilliam Wilgus
audio_play was removed from the rocklib I assume due to inconsistent behavior I've readded it with a check for audio paused which instead uses rewind/ff and then resumes audio the way to call the audio functions has changed as well rb.audio("option", var) so rb.audio_play(0, 0) becomes rb.audio("play", 0, 0) audio_audio_flush_and_reload_tracks becomes rb.audio("flushandreloadtracks") all functions except audio("getfilepos") return the previous (or still current) status added audio.lua to the includes for conversion to old functions if your script is broken by this change you simply add `require("audio")` to the top for the old functionality Change-Id: I364adf0c85d9c12b98cde29c26fbe5ee05b9d331

2018-10-24Lua fix strip_extension and create_numbered_filenameWilliam Wilgus
Both of these functions modified the string in the lua stack per lua manual: 'When a C function receives a string argument from Lua, there are only two rules that it must observe: Not to pop the string from the stack while accessing it and never to modify the string' strip_extension will still work with old parameters and is thus backwards compatible strip_extension("filename") create_numbered_filename has changed slightly and IS NOT backwards compatible create_numbered_filename(path, prefix, suffix, [number]) (number defaults to -1) Change-Id: I34cf7e2f6f691f33d5ac2b2e995855a171fb99b3
