CHAPTER 11. ADVANCED TOPICS 134
Alternating Sublines
It is possible to group items on each line into 2 or more groups or “sublines”. Each
subline will be displayed in succession on the line for a specified time, alternating con-
tinuously through each defined subline.
Items on a line are broken into sublines with the semicolon ’;’ character. The display
time for each subline defaults to 2 seconds unless modified by using the ’%t’ tag to
specify an alternate time (in seconds and optional tenths of a second) for the subline to
be displayed.
Subline related special characters and tags:
; Split items on a line into separate sublines
%t Set the subline display time. The ’%t’ is followed by either integer seconds (%t5),
or seconds and tenths of a second (%t3.5).
Each alternating subline can still be optionally scrolled while it is being displayed,
and scrollable formats can be displayed on the same line with non-scrollable formats
(such as track elapsed time) as long as they are separated into different sublines. Exam-
ple subline definition:
EXAMPLE
%s%t4%ia;%s%it;%t3%pc %pr : Display id3 artist for 4 seconds,
Display id3 title for 2 seconds,
Display current and remaining track time
for 3 seconds,
repeat...
Conditionals can be used with sublines to display a different set and/or number of
sublines on the line depending on the evaluation of the conditional. Example subline
with conditionals:
EXAMPLE
%?it<%t8%s%it|%s%fn>;%?ia<%t3%s%ia|%t0>
The format above will do two different things depending if ID3 tags are present. If
the ID3 artist and title are present:
• Display id3 title for 8 seconds,
• Display id3 artist for 3 seconds,
• repeat. . .
If the ID3 artist and title are not present:
• Display the filename continuously.
Note that by using a subline display time of 0 in one branch of a conditional, a subline
can be skipped (not displayed) when that condition is met.
