Editing String Viewer

__FORCETOC__

=Description=
Is a feature available for non-retail PS3 models <!--exact models are unknown but for sure is non retail because the text string is named "msg_tool_string_viewer"-->

Accesible from an icon at [[XMB]] category {{Icon category settings}} [Settings] > [String Viewer]

Its position in settings category is defined by the '''settings_order''' 0x13 in [[category_setting_plugin]].sprx (In XMB is displayed as the last icon most at bottom of settings category)

The name of the icon is loaded from [[category_setting_plugin]].rco
 <Text name="msg_tool_string_viewer">String Viewer</Text>

The icon launches [[strviewer_plugin]].sprx module

There are 4 "xml object pages" inside [[strviewer_plugin]].rco that can be loaded from the .sprx (the samples below are a reduced version with only its '''name''' and the action triggered when '''onInit'''):
 <Page name="page_strviewer_lang"... onInit="event:native:/OnInitStrViewerLang"...
 <Page name="page_strviewer_plugin"... onInit="event:native:/OnInitStrViewerPlugIn"...
 <Page name="page_strviewer_id"... onInit="event:native:/OnInitStrViewerID"...
 <Page name="page_strviewer"... onInit="event:native:/OnInitStrViewerDialog"...

String Viewer supports multilanguage. The page '''page_strviewer_lang''' contains a list of languages asociated with letter codes, see: [[Talk:Languages]]

=Speculation=
Maybe is posible to make visible the icon in some PS3 models by using a [[Button Combos|Button Combo]]

=Pre-retail firmwares=
In old firmwares can be seen how string viewer was loaded
{{Boxcode|code=<syntaxhighlight lang="xml">
<View id="seg_string_viewer">
	<Attributes>
		<Table key="StrViewer">
			<Pair key="icon_rsc"><String>item_tex_ms_icon</String></Pair>
			<Pair key="title"><String>String Viewer</String></Pair>
			<Pair key="module_name"><String>strviewer_plugin</String></Pair>
			<Pair key="module_action"><String>0</String></Pair>
		</Table>
	</Attributes>
	<Items>
		<Item  class="type:x-xmb/module-action" key="StrViewer" attr="StrViewer" />
	</Items>
</View>
</syntaxhighlight>}}
<div style="float:right">[[File:String viewer usb error.jpg|400px|thumb|left|String Viewer error]]</div>
When adding this entry in a modern firmware and clicking in the icon, appears an error message asking for '''strviewer_cnf''' in dev_usb000
<br style="clear: both;" />

The file in path '''usb000/strviewer/strviewer_cnf''' needs to follow this format:
{{Boxcode|code=<syntaxhighlight lang="xml">Title = "Strviwer Pwned" path = "/strviewer/" file = "working_example"</syntaxhighlight>}}

And the loaded xml seems to be using the format inherited from the '''dev_flash/vsh/resource/silk/xai/widgets/informationboard/strings/[[Widgets#dev_flash.2Fvsh.2Fresource.2Fsilk.2Fxai.2Fwidgets.2Finformationboard.2Fstrings.2F|infob_<language>.xml]]''' where is required to follow this format:
{{Boxcode|code=<syntaxhighlight lang="xml">
<str id="msg_dtype_C">Lorem ipsum...</str><!--dtype="C"-->
<str id="msg_dtype_E">Lorem ipsum...</str><!--dtype="E"-->
<str id="msg_dtype_W">Lorem ipsum...</str><!--dtype="W"-->
<str id="msg_dtype_R">Lorem ipsum...</str><!--dtype="R"-->
<str id="msg_dtype_T">Lorem ipsum...</str><!--dtype="T"-->
<str id="msg_dtype_N">This is a notification</str><!--dtype="N"-->
<str id="msg_dtype_G">This is a botton notification </str><!--dtype="G"-->
<str id="msg_dtype_I">This simple text was automatically repeated several times and also added many asterisks of its own</str<!--dtype="I"-->
</syntaxhighlight>}}
The valid values for the <nowiki><!--dtype="C"--></nowiki> (C,E,W,R,T,N,G,I) are hardcoded inside strviewer_plugin.sprx
