\chapter{\label{ref:wps_tags}Theme Tags}
Themeing is discussed in detail in section \reference{ref:ConfiguringtheWPS},
what follows is a list of the available tags.

\note{The ``bar-type tags'' (such as \%pb, \%pv, \%bl etc.) can be further
  themed -- see \reference{ref:bar_tags}.}

\section{Status Bar}
\begin{tagmap}
  \config{\%we} & Display Status Bar\\
  \config{\%wd} & Hide Status Bar\\
  \config{\%wi} & Display the inbuilt Status Bar in the current viewport\\
\end{tagmap}
These tags override the player setting for the display of the status bar.
They must be noted on their own line (which will not be shown in the WPS).

\section{Hardware Capabilities}
\begin{tagmap}
    \config{\%cc} & Check for presence of a real time clock, returns ``c''
                   when used unconditionally\\
    \config{\%tp} & Does this target have a radio?\\
    \config{\%Tp} & Indicates that the target has a touchscreen\\
\end{tagmap}
With the above tags it is possible to find out about the presence of certain
hardware and make the theme adapt to it. This can be very useful for designing
a theme that works on multiple targets with differing hardware capabilities, e.g.
targets that do and do not have a clock. When used conditionally, the ``true''
branch is completely ignored if it does not apply.

Example:
\config{\%?cc<\%cH:\%cM|No clock detected>}


\section{Information from the track tags}
  \begin{tagmap}
    \config{\%ia} & Artist\\
    \config{\%ic} & Composer\\
    \config{\%iA} & Album Artist\\
    \config{\%id} & Album Name\\
    \config{\%iG} & Grouping\\
    \config{\%ig} & Genre Name\\
    \config{\%in} & Track Number\\
    \config{\%it} & Track Title\\
    \config{\%iC} & Comment\\
    \config{\%iv} & ID3 version (1.0, 1.1, 2.2, 2.3, 2.4, or empty if not an ID3 tag)\\
    \config{\%iy} & Year\\
    \config{\%ik} & Disc Number\\
  \end{tagmap}
Remember that this information is not always available, so use the 
conditionals to show alternate information in preference to assuming.

These tags, when written with a capital ``I'' (e.g. \config{\%Ia} or \config{\%Ic}),
show the information for the next song to be played.

\nopt{lcd_charcell}{
  \section{Viewports}
    \begin{tagmap}
      \nopt{lcd_non-mono}{%
        \config{\%V(x,y,[width],\tabnlindent[height],[font])}
        & See section \ref{ref:Viewports}\\}

      \nopt{lcd_color}{\opt{lcd_non-mono}{%
        \config{\%V(x,y,[width],\tabnlindent[height],[font])}\newline
        \config{\%Vf([fgshade])}\newline
        \config{\%Vb([bgshade])}
        & See section \ref{ref:Viewports}\\}}

      \opt{lcd_color}{%
        \config{\%V(x,y,[width],\tabnlindent[height],[font])}\newline
        \config{\%Vf([fgcolour])}\newline
        \config{\%Vb([bgcolour])}
        & See section \ref{ref:Viewports}\\}
        
      \config{\%Vl('identifier',\newline\dots)} & Preloads a viewport for later
      display. `identifier' is a single lowercase letter (a-z) and the `\dots'
      parameters use the same logic as the \%V tag explained above.\\

      \config{\%Vd('identifier')} & Display the `identifier' viewport. E.g.
      \config{\%?C<\%Vd(a)|\%Vd(b)>}
      will show viewport `a' if album art is found, and `b' if it isn't.\\

      \config{\%Vi('label',\dots)} &
      Declare a Custom UI Viewport. The `\dots' parameters use the same logic as
      the \config{\%V} tag explained above. See section \ref{ref:Viewports}.\\ 

      \config{\%VI('label')} & Set the Info Viewport to use the viewport called
      label, as declared with the previous tag.\\
    \end{tagmap}

  \section{Additional Fonts}
    \begin{tagmap}
      \config{\%Fl('id',filename)} & See section \ref{ref:multifont}.\\
    \end{tagmap}

}

\section{Power Related Information}
  \begin{tagmap}
    \config{\%bl} & Numeric battery level in percents.
                    Can also be used in a conditional: 
                    \config{\%?bl<-1|0|1|2|\ldots|N>},
                    where the value $-1$ is used when the battery level isn't
                    known (it usually is). The value $N$ is only used when the
                    battery level is exactly 100 percent.
                    An image can also be used, the proportion of the image
                    shown corresponds to the battery level:
                    \config{\%bl(x,y,[width],[height],image.bmp)}\\
    \config{\%bv} & The battery level in volts\\
    \config{\%bt} & Estimated battery time left\\
    \config{\%bp} & ``p'' if the charger is connected (only on targets
                    that can charge batteries)\\
    \config{\%bc} & ``c'' if the unit is currently charging the battery (only on
                    targets that have software charge control or monitoring)\\
    \config{\%bs} & Remaining time of the sleep timer (if it is set)\\
  \end{tagmap}

\section{Information about the file}
  \begin{tagmap}
    \config{\%fb} & File Bitrate (in kbps)\\
    \config{\%fc} & File Codec (e.g. ``MP3'' or ``FLAC'').
           This tag can also be used in a conditional tag:
           \config{\%?fc<mp1|mp2|mp3|aiff|wav|ogg|\newline
           flac|mpc|a52|wavpack|alac|aac|shn|sid|adx|nsf|\newline
           speex|spc|ape|wma|mod|sap|unknown>}.
                  The codec order is as follows: MP1, MP2, MP3, AIFF, WAV,
           Ogg Vorbis (OGG), FLAC, MPC, AC3, WavPack (WV), ALAC, AAC,
           Shorten (SHN), SID, ADX, NSF, Speex, SPC, APE, WMA, MOD, SAP.\\
    \config{\%ff} & File Frequency (in Hz)\\
    \config{\%fk} & File Frequency (in kHz)\\
    \config{\%fm} & File Name\\
    \config{\%fn} & File Name (without extension)\\
    \config{\%fp} & File Path\\
    \config{\%fs} & File Size (in Kilobytes)\\
    \config{\%fv} & ``(avg)'' if variable bit rate or empty string if constant bit rate\\
    \config{\%d(N)} & N-th segment from the end of the file's directory
                       (N can be 1, 2, 3, \dots)\\
  \end{tagmap}
Example for the \config{\%d(N)} commands: If the file is
``/Rock/Kent/Isola/11 - 747.mp3'', \config{\%d(1)} is ``Isola'', 
\config{\%d(2)} is ``Kent'' and \config{\%d(3)} is ``Rock''.

These tags, when written with the first letter capitalized (e.g. \config{\%Fn}
or \config{\%D(2)}), produce the information for the next file to be played.

\section{Playlist/Song Info}
  \begin{tagmap}
    \config{\%pb} & Progress Bar.
    \opt{player}{
            This will display a one character ``cup''
            that empties as the time progresses.}
    \opt{lcd_bitmap}{
           This will replace the entire line with a progress bar.
           You can set the position, width and height of the progressbar
           (in pixels) and load a custom image for it:
           \config{\%pb(x,y,[width],[height],image.bmp)}} \\
    \opt{player}{%
    \config{\%pf} & Full-line progress bar \& time display\\
    }%
    \config{\%px} & Percentage played in song\\
    \config{\%pc} & Current time in song\\
    \config{\%pe} & Total number of playlist entries\\
    \nopt{player}{%
    \config{\%pm} & Peak Meter. The entire line is used as %
                    volume peak meter.\\%
    }%
    \config{\%pn} & Playlist name (without path or extension)\\
    \config{\%pp} & Playlist position\\
    \config{\%pr} & Remaining time in song\\
    \config{\%ps} & ``s'' if shuffle mode is enabled\\
    \config{\%pt} & Total track time\\
    \config{\%pv} & Current volume (in dB). Can also be used in a conditional:
           \config{\%?pv<0|1|2|\ldots|N>}\newline
           0 is used for mute, the last option is used for values greater than zero.
         \opt{lcd_bitmap}{This can also be used like \%pb to provide a continuous scale:
         \config{\%pv(x,y,[width],[height],image.bmp)}} \\
    \config{\%pS} & Track is starting. An optional number gives how many seconds
         the tag remains true for after the start of the track. The default is
         10 seconds if no number is specified.
         \config{\%?pS(7)<in the first 7 seconds of track|in
           the rest of the track>}\\
    \config{\%pE} & Track is ending. An optional number gives how many seconds
         before the end of the track the tag becomes true. The default is
         10 seconds if no number is specified.
         \config{\%?pE(7)<in the last 7 seconds of track|in
           the rest of the track>}\\
    \config{\%Sp} & Current playback pitch\\
  \end{tagmap}
  
\section{Playlist Viewer}
  \begin{tagmap}
    \config{\%Vp(start,code to render)} & Display the playlist viewer in
            the current viewport.\\
  \end{tagmap}

  \begin{itemize}
    \item `start' is the offset relative to the currently playing track for the
    playlist to display from (0 the current track, 1 is the next track, etc.).
    \item `code to render' is a line of skin code which will be displayed for
    each line in the viewer. All text tags are supporte (including conditionals
    and sublines)
  \end{itemize}

  The entire viewport will be used, so don't expect other tags in the same
  viewport to work well.  Supported tags are \%pp, all tags starting with \%i,
  most tags starting with \%f, \%pt and \%s.\\

  Example: \config{\%Vp(1,\%pp - \%it,\%pp - \%fn)} -- Display the playlist
  position, then either the track title (from the tags) or
  the filename. The viewer will display as many tracks as will fit in the
  viewport.

\section{Runtime Database}
  \begin{tagmap}
    \config{\%rp} & Song playcount\\
    \config{\%rr} & Song rating (0-10). This tag can also be used in a conditional tag: %
           \config{\%?rr<0|1|2|3|4|5|6|7|8|9|10>}\\
    \config{\%ra} & Autoscore for the song\\
  \end{tagmap}

\opt{swcodec}{
\section{Sound (DSP) settings}
  \begin{tagmap}
    \config{\%Sp} & Current playback pitch \\
  \opt{swcodec}{
    \config{\%xf} & Crossfade setting, in the order: Off, Auto Skip, Man Skip,
           Shuffle, Shuffle and Man Skip, Always\\
    \config{\%rg} & ReplayGain value in use (x.y~dB). If used as a conditional,
           Replaygain type in use: \config{\%?rg<Off|Track%
           |Album|TrackShuffle|AlbumShuffle%
           |No tag>}\\
  }
  \end{tagmap}
}

\section{Hold}
    \begin{tagmap}
        \config{\%mh} & ``h'' if the main unit keys are locked\\
        \opt{remote_button_hold}{%
            \config{\%mr} & ``r'' if the remote keys are locked\\
        }
    \end{tagmap}

\section{Virtual LED}
  \begin{tagmap}
    \config{\%lh} & ``h'' if the \disk\ is accessed\\
  \end{tagmap}

\section{Repeat Mode}
  \begin{tagmap}
    \config{\%mm} & Repeat mode, 0-4, in the order: Off, All, One, Shuffle, A-B\\
  \end{tagmap}
Example: \config{\%?mm<Off|All|One|Shuffle|A-B>}

\section{Playback Mode}
  \begin{tagmap}
    \config{\%mp} & Play status, 0-4, in the order: Stop, Play, Pause, 
           Fast Forward, Rewind, Recording, Recording paused, FM Radio playing,
           FM Radio muted\\
  \end{tagmap}
Example: \config{\%?mp<Stop|Play|Pause|Ffwd|Rew|Rec|Rec pause|FM|FM pause>}

\section{Current Screen}
  \begin{tagmap}
    \config{\%cs} & The current screen, 1-5, in the order:
                Menus, WPS, Recording screen, FM Radio screen, Current Playlist screen\\
  \end{tagmap}
The tag can also be used as the switch in a conditional tag. For players without
some capabilities (e.g. having no FM radio) some values will be never yielded.

Example: \config{You are in the \%?cs<Main menu|WPS|Recording screen|FM Radio screen>}

\section{List Title (\fname{.sbs} only)}
  \begin{tagmap}
    \config{\%Lt} & Title text. Should be used in a conditional so that non-list
      screens don't show a title when they shouldn't\\
    \config{\%Li} & Title icon. This uses the same order as custom icons (see
      \wikilink{CustomIcons} in the wiki) except that here \config{0} is ``no
      icon''\\
  \end{tagmap}

  This tag can be used to give custom formatting to list titles.
  Define a viewport with the font and formatting desired, and then use
  \config{\%?Lt<\%Lt>} to display the title within the
  viewport.  If \config{\%Lt} is present anywhere in the \fname{.sbs}, then the
  \config{\%Vi} viewport will not show the title.

\section{Changing Volume}
  \begin{tagmap}
    \config{\%mv(t)} & ``v'' if the volume is being changed\\
  \end{tagmap}

The tag produces the letter ``v'' while the volume is being changed and some
amount of time after that, i.e. after the volume button has been released. The
optional parameter \config{t} specifies that amount of time, in seconds. If it
is not specified, 1 second is assumed.

The tag can be used as the switch in a conditional tag to display different things
depending on whether the volume is being changed. It can produce neat effects
when used with conditional viewports.

Example: \config{\%?mv(2.5)<Volume changing|\%pv>}

The example above will display the text ``Volume changing'' if the volume is
being changed and 2.5 seconds after the volume button has been released. After
that, it will display the volume value.

\section{Settings}
  \begin{tagmap}
    \config{\%St(<setting\tabnlindent{}name>)} & The value of the Rockbox
             setting with the specified name. See \reference{ref:config_file_options}
             for the list of the available settings.\\
  \end{tagmap}

Examples:
\begin{enumerate}
\item As a simple tag: \config{\%St(skip length)}
\item As a conditional: \config{\%?St(eq enabled)<Eq is enabled|Eq is disabled>}
\end{enumerate}


\opt{lcd_bitmap}{
\section{\label{ref:wps_images}Images}
  \begin{tagmap}
    \nopt{archos}{%
    \config{\%X(filename.bmp)}
        & Load and set a backdrop image for the WPS.
          This image must be exactly the same size as your LCD.\\
    }%
    \config{\%x(n,filename,x,y)}
        & Load and display an image\newline
          \config{n}: image ID (a-z and A-Z) for later referencing in \config{\%xd}\newline
          \config{filename}: file name relative to \fname{/.rockbox/} and including ``.bmp''\newline
          \config{x}: x coordinate\newline
          \config{y}: y coordinate.\\
    \config{\%xl(n,filename,x,y,\tabnlindent[nimages])}
        & Preload an image for later display (useful for when your images are displayed conditionally).\newline
          \config{n}: image ID (a-z and A-Z) for later referencing in \config{\%xd}\newline
          \config{filename}: file name relative to \fname{/.rockbox/} and including ``.bmp''\newline
            If the filename is ``\_\_list\_icons\_\_'' the list icon bitmap will be used instead\newline
          \config{x}: x coordinate\newline
          \config{y}: y coordinate\newline
          \config{nimages}: (optional) number of sub-images (tiled vertically, of the same height)
          contained in the bitmap. Default is 1.\\
    \config{\%xd(n[i] [,tag] [,offset])} & Display a preloaded image.
          \config{n}: image ID (a-z and A-Z) as it was specified in \config{\%x} or \config{\%xl}\newline
          \config{i}: (optional) number of the sub-image to display (a-z for 1-26 and A-Z for 27-52). 
          (ignored when \config{tag} is used)
          By default the first (i.e. top most) sub-image will be used.\newline
          \config{tag}: (optional) Another tag to calculate the subimage from e.g \config{\%xd(A, \%mh)} would
          use the first subimage when \config{\%mh} is on and the second when it is off\newline
          \config{offset}: (optional) Add this number to the value from the \config{tag} when 
          chosing the subimage (may be negative)\\
  \end{tagmap}

Examples:
\begin{enumerate}
\item Load and display the image \fname{/.rockbox/bg.bmp} with ID ``a'' at 37, 109:\\
\config{\%x(a,bg.bmp,37,109)}
\item Load a bitmap strip containing 5 volume icon images (all the same size)
with image ID ``M'', and then reference the individual sub-images in a conditional:\\
\config{\%xl(M,volume.bmp,134,153,5)}\\
\config{\%?pv<\%xd(Ma)|\%xd(Mb)|\%xd(Mc)|%
\%xd(Md)|\%xd(Me)>}
\end{enumerate}


\note{
  \begin{itemize}
  \item The images must be in BMP format
  \item The image tag must be on its own line
  \item The ID is case sensitive, giving 52 different ID's
  \item The size of the LCD screen for each \dap{} varies. See table below 
        for appropriate sizes of each device. The x and y coordinates must 
        respect each of the \daps{} limits.
  \end{itemize}
}
}

\opt{albumart}{
\section{\label{ref:album_art}Album Art}
Rockbox allows you to put the album art, or another image related to the music
on your \dap{} to display it in the PictureFlow plugin\opt{albumart}{ or in the
theme}. For this feature to work, there are a few requirements.

\subsection{Limitations}

Rockbox does not support album art embedded in your files' tags, and will
instead look for a picture located on disk. In addition to this, the
pictures must be in either BMP or JPEG format. Rockbox does not support
RLE-compressed BMP files, nor does it support progressive and multi-scan
JPEG files. JPEG files must consist of a single scan with interleaved components, 
as progessive and multi-scan images require much more memory to decode.

\subsection{Where to put album art}

The pictures can be named a number of different ways, and placed to a number of
different locations. You can have pictures specific to the file or the album
or use a generic picture. You can place the picture in the same directory
as the file, in the parent directory or in a fixed directory named
\fname{/.rockbox/albumart/}. The order Rockbox uses when looking for a picture
is as follows (a list in braces means that those file extensions are tried in
that order):

\begin{enumerate}
\item  \fname{./filename.\{jpeg,jpg,bmp\}}
\item  \fname{./albumtitle.\{jpeg,jpg,bmp\}}
\item  \fname{./cover.\{jpeg,jpg,bmp\}}
\item  \fname{./folder.jpg}
\item  \fname{/.rockbox/albumart/albumartist-albumtitle.\{jpeg,jpg,bmp\}}
\item  \fname{../albumtitle.\{jpeg,jpg,bmp\}}
\item  \fname{../cover.\{jpeg,jpg,bmp\}}
\end{enumerate}

The following characters will be replaced with an underscore (\_) when looking
for albumtitle.bmp or albumartist-albumtitle.bmp: \textbackslash{} / : <
> ? * |. Doublequotes will be replaced by single quotes.
If no album artist is set, artist will be used instead. See \wikilink{AlbumArt}
in the wiki for programs that will help you automate the process of putting
album art on your \dap{}.

\subsection{How to display the album art}

Once the album art files are present on your \dap, they can be displayed as
follows.

  \begin{tagmap}
    \config{\%Cl(x,y,[maxwidth],\tabnlindent[maxheight],\tabnlindent{}hor\_align,\tabnlindent{}vert\_align)}
        & Define the settings for album art\newline
          \config{x}: x coordinate\newline
          \config{y}: y coordinate\newline
          \config{maxwidth}: Maximum height\newline
          \config{maxheight}: Maximum width\newline
          \config{hor\_align}: Horizontal alignment, enter as `l', `c' or `r' for
          left, centre or right. Centre is default\newline
          \config{vert\_align}: Vertical alignment, enter as `t', `c' or `b' for
          top, centre or bottom. Centre is default\\
    \config{\%Cd}  & Display the album art as configured. \\
    \config{\%C}  & Use in a conditional to determine if an image is available. \\
  \end{tagmap}

The picture will be rescaled, preserving aspect ratio to fit the given
\config{maxwidth} and \config{maxheight}. If the aspect ratio doesn't match the
configured values, the picture will be placed according to the alignment flags.

Examples:
\begin{enumerate}
  \item Load albumart at position 20,40 and display it without resizing:\\
  \config{\%Cl(20,40,,)}
  \item Load albumart at position 0,20 and resize it to be at most 100$\times$100
        pixels. If the image isn't square, align it to the bottom-right
        corner:\\
  \config{\%Cl(0,20,100,100,r,b)}
\end{enumerate}
}

\opt{radio}{
\section{FM Radio}
  \begin{tagmap}
    \config{\%tt} & Is the tuner tuned?\\
    \config{\%tm} & Scan or preset mode? Scan is ``true'', preset is ``false''.\\
    \config{\%ts} & Is the station in stereo?\\
    \config{\%ta} & Minimum frequency (region specific) in MHz.\\
    \config{\%tb} & Maximum frequency (region specific) in MHz.\\
    \config{\%tf} & Current frequency in MHz.\\
    \config{\%Ti} & Current preset id, i.e. 1-based number of the preset
      within the presets list (usable in playlist viewer).\\
    \config{\%Tn} & Current preset name (usable in playlist viewer).\\
    \config{\%Tf} & Current preset frequency (usable in playlist viewer).\\
    \config{\%Tc} & Preset count, i.e. the number of stations in the current
      preset list.\\
    \config{\%tx} & Is RDS available?\\
    \config{\%ty} & RDS name.\\
    \config{\%tz} & RDS text.\\
    \config{\%tr} & Signal strength (RSSI). Can be used in a conditional or as
      a bar.\\
  \end{tagmap}

It is also possible to show ``Radio Art'' which can be used to display images
associated with presets. The tags are exactly the same as for album art,
described above. Images need to be placed in \fname{/.rockbox/fmpresets/},
and must have the same name as the preset. They need to be in either
\fname{.bmp} or \fname{.jpg} format, and the radio must be in preset mode
and tuned to a preset (and not recording) in order for them to be shown.
}

\section{Alignment and language direction}
  \begin{tagmap}
    \config{\%al} & Align the text left\\
    \config{\%aL} & Align the text left, or to the right if RTL language is in use\\
    \config{\%ac} & Centre the text\\
    \config{\%ar} & Align the text right\\
    \config{\%aR} & Align the text right, or to the left if RTL language is in use\\
    \config{\%ax} & The next tag should follow the set language direction. When
                    prepended to a viewport declaration, the viewport will
                    be horizontally mirrored if the user language is set to
                    a RTL language. Currently the \%Cl, \%V and \%Vl tags
                    support this.\\
    \config{\%Sr} & Use as a conditional to define options for left to right, or
                    right to left languages. \%?Sr<RTL|LTR>\\
  \end{tagmap}
  
All alignment tags may be present in one line, but they need to be in the 
order left -- centre -- right. If the aligned texts overlap, they are merged.

Example: \config{\%ax\%V(\dots)}

\section{Conditional Tags}

\begin{tagmap}
\config{\%?xx<true|false>}
    & If / Else: Evaluate for true or false case \\
\config{\%?xx<alt1|alt2|\tabnlindent{}alt3|\dots|else>}
    & Enumerations: Evaluate for first / second / third / \dots / last condition \\
\config{\%if(tag, operator, operand, [option count])}
    & Allows very simple comparisons with other tags.\newline
      \config{tag}: the tag to check against.\newline
      \config{operator}: the comparison to perform - possible options are =, !=,
        >, >=, <, <=\newline
      \config{operand}: either a second tag, a number, or text.\newline
      \config{[option count]}: optional parameter used to select which parameter
        of a tag to use when the tag has multiple options, e.g. \%?pv<a|b|c|d>\\
\end{tagmap}

Examples of the \%if tag:\\

\config{\%?if(\%pv, >=, 0)<Clipping possible|Volume OK>} will display ``Clipping
  possible'' if the volume is higher than or equal to 0 dB, ``Volume OK'' if it
  is lower.\\

\config{\%?if(\%ia, =, \%Ia)<same artist>} -- this artist and the next artist
  are the same.\\

\note{When performing a comparison against a string tag such as \%ia, only = and
  != work, and the comparison is not case sensitive.}

\section{Subline Tags}

\begin{tagmap}
\config{\%t(time)}
    & Set the subline display cycle time (\%t(5) or \%t(3.4) formats) \\
\config{;}
    & Split items on a line into separate sublines \\
\end{tagmap}

Allows grouping of several items (sublines) onto one line, with the
display cycling round the defined sublines. See
\reference{ref:AlternatingSublines} for details. 

\opt{rtc}{
\section{Time and Date}
    \begin{tagmap}
      \config{\%cd}          & Day of month from 01 to 31\\
      \config{\%ce}          & Zero padded day of month from 1 to 31\\
      \config{\%cf}          & A conditional for 12/24 hour format.\newline
                               \config{\%?cf<24 hour stuff|12 hour stuff>}\\
      \config{\%cH}          & Zero padded hour from 00 to 23 (24 hour format)\\
      \config{\%ck}          & Hour from 0 to 23 (24 hour format)\\
      \config{\%cI}          & Zero padded hour from 01 to 12 (am/pm format)\\
      \config{\%cl}          & Hour from 1 to 12 (am/pm format)\\
      \config{\%cm}          & Month from 01 to 12\\
      \config{\%cM}          & Minutes\\
      \config{\%cS}          & Seconds\\
      \config{\%cy}          & 2-digit year\\
      \config{\%cY}          & 4-digit year\\
      \config{\%cP}          & Capital AM/PM\\
      \config{\%cp}          & Lowercase am/pm\\
      \config{\%ca}          & Weekday name\\
      \config{\%cb}          & Month name\\
      \config{\%cu}          & Day of week from 1 to 7, 1 is Monday\\
      \config{\%cw}          & Day of week from 0 to 6, 0 is Sunday\\
    \end{tagmap}
}

\section{Text Translation}
  \begin{tagmap}
    \config{\%Sx(English)}
    & Display the translation of ``English'' in the current language\\
  \end{tagmap}
  
  \begin{itemize}
    \item ``English'' must be a phrase used in the language file.
    \item It should match the \config{Source:} line in the language file.
  \end{itemize}

  \note{checkwps cannot verify that the string is correct, so please check on
    either the simulator or on target.}


\opt{touchscreen}{
  \section{Touchscreen Areas}
    \begin{tagmap}
      \config{\%T(x,y,[width],\tabnlindent[height],action)}
      & Invoke the action specified when the user presses in the defined
      touchscreen area.\\
    \end{tagmap}
  If the action starts with \& then the area must be held. Possible actions are:

  \begin{description}
    \item[play] -- Play/pause playback.
    \item[stop] -- Stop playback and exit the WPS.
    \item[prev] -- Previous track.
    \item[next] -- Next track.
    \item[ffwd] -- Seek forwards in the track.
    \item[rwd] -- Seek backwards in the track.
    \item[menu] -- Go to the main menu.
    \item[browse] -- Go back to the file browser or database.
    \item[shuffle] -- Toggle shuffle mode.
    \item[repmode] -- Cycle through the repeat modes.
    \item[quickscreen] -- Go to the quickscreen.
    \item[contextmenu] -- Open the context menu.
    \item[playlist] -- Go to the playlist viewer.
    \item[progressbar] -- Seek to the appropriate position in the track based on the touch.
    \item[volume] -- Set the volume to the appropriate level based on the touch.
    \item[pitch] -- Open the pitchscreen.
    \item[voldown] -- Decrease the volume by one step.
    \item[volup] -- Increase the volume by one step.
    \item[mute] -- Un/Mute playback.
  \end{description}

  \section{Last Touchscreen Press}
    \begin{tagmap}
      \config{\%Tl} & Indicates that the touchscreen is pressed.\\
    \end{tagmap}
  This tag can be used to display text or images or a viewport when the
  touchscreen is pressed (like an On Screen Display). If you put a number
  straight after \%Tl it will be used as a timeout in seconds
  (e.g \%Tl(2.5) will give a 2.5 second timeout) between the touchscreen press
  being released and the tag going false. If no number is specified it will
  use a 1 second timeout.  It can also be used as a conditional, and can be
  used with conditional viewports.
}

\section{\label{ref:bar_tags}Bar Tags}
  Some tags can be used to display a bar which draws according to the value of
  the tag. To use these tags like a bar you need to use the following parameters
  (\%XX should be replaced with the actual tag).

\begin{tagmap}
  \config{\%XX(x, y, width, height, [options])}
    & Draw the specified tag as a bar\newline
      \config{x}: x co-ordinate at which to start drawing the bar.\newline
      \config{y}: y co-ordinate at which to start drawing the bar.\newline
      \config{width}: width of the bar (- for the full viewport width).\newline
      \config{height}: height of the bar (- to set to the font height for
        horizontal bars and to the viewport height for vertical bars).\newline
      \config{options}: any of the options set out below.\\
\end{tagmap}

\subsection{Options}
\begin{description}
  \item[image] -- the next option is either the filename or image label to
    use for the fill image.
  \item[horizontal] -- force the bar to be drawn horizontally.
  \item[vertical] -- force the bar to be drawn vertically.
  \item[invert] -- invert the draw direction (i.e. right to left, or top to
    bottom).
  \item[slider] -- draw an preloaded image over the top of the bar so that
    the centre of the image matches the current position. This must be
    followed by the label of the desired image.
  \item[nofill] -- don't draw the bar, only its frame (for use with the
     ``slider'' option).
  \item[nobar] -- don't draw the bar or its frame (for use with the
    ``slider'' option).
\end{description}

Example: \config{\%pb(0,0,-,-,-,nofill, slider, slider\_image, invert)} -- draw
a horizontal progressbar which doesn't fill and draws the image
``slider\_image'' which moves right to left.

\note{If the slider option is used, the bar will be shrunk so that the slider
  fits inside the specified width and height.}

                           displayed; see conditionals above). You can specify 
                           up to ten scrolling lines. Scrolling lines can not 
                           contain dynamic content such as timers, peak meters 
                           or progress bars.\\
