10:35 < TheSeven> that's the magic string that makes the apple bootloader boot diskmode on the next reboot
10:37 < user890104> thanks
10:40 < user890104> i've made changes to my serial number patch, it can handle serial numbers up to 496 chars, so it should be compatible with any device that gets an emcore port: http://pastebin.com/raw.php?i=mWQ7ST4a
10:45 < user890104> and i'm trying to implement some kind of file browser using libui right now
10:45 < user890104> i managed to make the list using a dynamic allocations after some trial and error
10:51 < TheSeven> yeah, you basically need to preallocate the list memory for the maximum possible number of elements, or first count all the files and then allocate it once you know the size

14:12 < user890104> TheSeven: any suggestions how to name the folder where user-uploaded apps would be stored? for example Apps or Applications (as on OSX :) ) ?
14:13  * TheSeven suggests "/.apps"
14:13 < TheSeven> [12:51:56] <TheSeven> yeah, you basically need to preallocate the list memory for the maximum possible number of elements, or first count all the files and then allocate it once you know the size
14:13 < TheSeven> the action and renderer params can be allocated on the fly, but it's kinda hard to keep track of them and not leak anything
14:14 < TheSeven> it might be easier to use one big allocation that contains everything, that also reduces fragmentation and overhead (8 bytes per allocation)
14:14 < TheSeven> it needs a bigger contiguous chunk of free memory of course
14:17 < user890104> here's what i've done so far: http://pastebin.com/Y3D3YhaN
14:17 < user890104> it just makes 20 menu items
14:18 < user890104> (and it's a bit ugly)
14:25 < TheSeven> hm, is there are particular reason why you copy the chooser definition around?
14:25 < TheSeven> a*
14:25 < TheSeven> seems like you could just use the "master copy" directly
14:26 < TheSeven> also, this line looks a bit strange to me:
14:26 < TheSeven>     if (!lib) lib = get_library(identifier, version, LIBSOURCE_RAM_ALLOCED, (void *) 0x08000C68);
14:26 < user890104> this is because i tried to run libui on a nano4g :)
14:27 < TheSeven> there's an easier way to do this
14:27 < TheSeven> just launch the lib as if it was an app, and then launch the app using it
14:28 < TheSeven> as the lib is already in memory in this case, the source definition won't be used at all, so it's fine if it points to the bootflash
14:34 < user890104> is there a limit of the number of files in a directory on fat32?
14:37 < TheSeven> i don't think so
14:37 < user890104> i copy the chooser_info struct in a new buffer that has enough space to fit the required number of items
14:37 < user890104> buecause i don't know how to "resize" the array once allocated
14:37 < user890104> because*
14:37 < TheSeven> oh, so this means that memcpy(chooser, &toolchooser, sizeof(struct chooser_info) + itemlimit * sizeof(struct chooser_item)); is copying some garbage as wellß
14:37 < TheSeven> ?
14:38 < user890104> well ...
14:38 < user890104> i zero out every item below
14:38 < user890104> i just don't know a better way to do this
14:39 < TheSeven> just use sizeof(toolchooser) as the size for memcpy?
14:40 < user890104> is there ay difference between sizeof something and sizeof(something)?
14:40 < TheSeven> i don't think so, but the first one is syntactically weird

15:17 < user890104> emcore frees up the memory allocated by an app but not explictly freed after the app exits, right?
15:25 < [7]> yeah, but you shouldn't rely on that
15:26 < user890104> yeah i know, just asking
15:26 < user890104> is this the proper way to list a directory? http://pastebin.com/Lim0YjHW
15:26 < user890104> i mean do i need 2 pointers?

16:58 < user890104> TheSeven: so with the structure you proposed, the /.apps folder will look like:
16:58 < user890104>  |- app1.emcoreapp
16:58 < user890104>  |- app1
16:58 < user890104>  |- app2.emcoreapp
16:58 < user890104>  |- app2
16:59 < user890104> (app1 and app2 being folders that hold the app's settings)
17:24 < TheSeven> hm, i'm wondering if the emcoreapp files should be inside the app folder as well
17:24 < TheSeven> (in the same place as their resources etc.)
17:24 < TheSeven> we'll probably need a way to determine where an app was launched from, so that it can find its resources, even if it installed in a different location
17:26 < user890104> installed in means of what?
17:26 < user890104> i assume that an app would look for its settings in /.apps/<app name>/ no matter how/where it is located
17:27 < user890104> that's why i asked you about the location of .emcoreapps
17:27 < Farthen> that would be my opinion, too
17:29 < user890104> so the applications folder could be something that's clearly visible to the user
17:29 < user890104> because he/she is supposed to modify manually its contents
17:29 < user890104> by uploading/removing apps.. so i proposed Apps or Applications
17:30 < user890104> what do you think?
