Subject: Viewing Files With Plugins Proof of concept

Viewing Files With Plugins Proof of concept

From: Henrik Backe <>
Date: Sun, 18 Jan 2004 21:01:15 +0100

I've finally submitted a proof of concept

It is my attemt to implement the scheme in mail

I've made a few changes to this scheme.
- /.rockbox/viewers.config and /.rockbox/viewers are
 read/scanned at bootup if no /.rockbox/.viewers.cache
 exist. This way we always know what extensions are
 supported, and we only get excessive file reads on the
 first boot.
- /.rockbox/viewers.config and /.rockbox/viewers are
 not read/scanned when a viewer plugin is called.
 Instead there is a refresh of .viewers.cache
  if a plugins is missing or have filesize zero.
- If a new viewer plugin is added .viewers.cache has to
 be refreshed, since this will not be done automagically
 I've added an option
  settings->system->manage settings->reset plugin list
- I've made the assumption that for example
 txt-viewer.rock and viewer.rock will be in
 the /.rockbox/viewers folder, and then no rocks with
 an extension prefix should be displayed in the
 onplay->"open with" menu.

Things left to do
- code policeing
- commenting of the code
- add splashes for some of the error conditions
- add language strings
- figure out a sane value for string_buffer in filetypes.c
  It's set to 1000 bytes, but I think it can be reduced.
- One known bug, A second reset of the plugin list will
 freeze the unit.

Daniel's patch mentioned in
should be applied before this patch.
