Viewing a File When a file is PLAYed, the following will be made in order to figure out what to do with the particular file: 1. Internally recognized extensions (.mp3, .m3u etc) (like today) 2. Extension config file ".rockbox/view.config". A config file lists extensions and what plugin (file name) that should be ran to view that particular file. This file is _not_ scanned at boot, but will be read and cached at first use. We could possibly have an option to parse it automaticly at boot. 3. Check if ".rockbox/viewer/[extension]-[anything].rock" exists, and if it does: use that. These plugins _are not_ scanned at boot nor after USB disconnect. 4. If none of the above worked, the file type is unsupported. No Rebuild Needed This enables users to add, remove or replace viewers at will with no rebuilds at all necessary, and without Rockbox even being aware of what plugins that exist or not. Plugins can finally become true 3rd party software. View With The "on play" screen can then get a "view with..." option that offers the user to view the currently selected file using one of the viewers present in the ".rockbox/viewer" directory. This would enable for example .m3u files to get viewed by the text viewer, or sending an mp3 file to a hex-editor etc. View Supported The concept of "view supported" files changes somewhat. Internally supported formats are of course present, but extensions in the "view.config" are only supported once the file has been read and and so are extensions that have been "verified to work". That means we've played one successfully and thus there was a plugin for it in the proper dir. Icons The 'view.config' file will have a field for this, see below for the file format. (The icon can also be provided as a separate file next to the plugin, as in "[extension]-[anything].icon", but this will then make it suffer from the same drawbaks as the "view supported" have. The icon file should then use the same syntax as the icon field of the view.config file). view.config File Format: Each line conists of extension, file name and icon data. extension TAB] plugin file name TAB 12 icon digits 00 12 34 56 67 89 example: # this is a comment line txt txt-viewer.rock 55 55 55 55 55 55 rvf rvf-video.rock 5d 7f 5d 7f 5d 7f html html-mozilla.rock Build System We would add a separate config file in the build system that makes viewer plugins get a suitable name for the viewer-directory when built. So that viewer.c becomes txt-viewer.rock and chip8.c becomes ch8-chip8.rock etc. If the plugin is not mentioned in this file, it would be named like today. (I already have work done on this that seems to mostly work.) -- Daniel Stenberg -- http://rockbox.haxx.se/ -- http://daniel.haxx.se/Received on 2004-01-13 Page template was last modified "Tue Sep 7 00:00:02 2021" The Rockbox Crew -- Privacy Policy |
