[mythtv] Attention all OSD theme maintainers/authors concerning

[Chris Pinkham]

I just added this, a %BR% can be inserted and will be converted to
a linefeed upon display.  so
"%DESCRIPTION%%BR%%STARTTIME% - %ENDTIME%%BR%%LENMINS% minutes" would
print this:

ER
10:00 PM - 11:00 PM
60 minutes

> One suggestion would be a keyword to insert a line break.

> information. An example is %DESCRIPTION% which gets replaced by the
> actual program description.
> 
> These keywords are used in new <value></value> tags in the osd.xml

> convert your themes over to using <value> whenever you can.  Keywords

>         <textarea name="description">
>             <multiline>yes</multiline>
>             <area>145,375,425,98</area>
>             <font>ShowDesc</font>
>             <value>%DESCRIPTION% (%STARTTIME%-%ENDTIME%)</value>
>         </textarea>
> 
> This would display something like this:
> 
> 	Wheel Of Fortune (7:00 PM-7:30 PM)
> 
> depending on how the user's date/time formats were configured in setup.
> 
> The <value> tag will replace the <statictext> tag.  If a value tag does
> not have any substitution keywords then it is copied directly.  All
> <textarea> fields do not require <value> tags.  If a textarea field
> called 'title' is left blank, then its value is assumed to be %TITLE%;
> 'subtitle' textarea field has assumed value of %SUBTITLE%, etc..
> Keywords must be in UPPERcase.
> 
> Here is a list of current keywords that can be used and what containers
> they may be used in.  We have the ability to start adding more, but
> these are enough to duplicate previous functionality and more.
> 
> program_info
> 	TITLE        - title
> 	SUBTITLE     - subtitle
> 	DESCRIPTION  - description
> 	CATEGORY     - category
> 	CALLSIGN     - station callsign
> 	STARTTIME    - start time in "TimeFormat" format
> 	STARTDATE    - start date in "ShortDateFormat" format
> 	ENDTIME      - end time in "TimeFormat" format
> 	ENDDATE      - end date in "ShortDateFormat" format
> 	CHANNUM      - channel number (channum field in channel table)
> 	LENTIME      - HH:MM length of program (ie, 1:30 is 1 hour, 30
> minutes)
> 	LENMINS      - length in minutes (ie, '90' for an hour and a
> half long show)
> 
> channel_number
> 	CHANNUM      - channel number (channum field in channel table)
> 	CALLSIGN     - station callsign
> 
> Only the program_info and channel_number OSD containers can use the new
> keyword functionality at this moment, but changing the code to allow
> other containers to use them will be fairly easy.
