Hi Chris,
This is a syntax issue. Let's add some space to your code so I can
show you:
radio = fallback([
# Switch begins
switch([
({ 1w },monday),
({ 2w },tuesday),
({ 3w }, wednesday),
({ 4w }, thursday),
({ 5w }, friday),
({ 6w }, saturday),
({ 7w }, sunday)
]), # Switch ends
Fall]) # Back at the fallback
Previously, Fall was part of the list of switch elements, which are
supposed to be pairs and not just a source: that was your error messages.
Good indentation helps making the code readable but also, it's usually
good to split things so as to avoid nested code. For instance, here:
# First the switch
s = switch([
({ 1w },monday),
({ 2w },tuesday),
({ 3w }, wednesday),
({ 4w }, thursday),
({ 5w }, friday),
({ 6w }, saturday),
({ 7w }, sunday)
])
# Then the fallback:
radio = fallback([s,Fall])
Also, you might want to be aware of the `track_sensitive` parameter
for switch and fallback, in the case where you'd expect the transition
to happen right away and not after the end of the current track.
Hope this helps!

Hi all,
I'm trying to get my first LiquidSoap script to work and not sure
what
the issue is. The script I generated mainly looking at the Cookbook
online is:
> #!/usr/bin/liquidsoap
>
> #DOWs feeds
> monday = playlist(mode="normal", "~/radio/playlist/monday.m3u")
> tuesday = playlist(mode="normal","~/radio/playlist/tuesday.m3u")
> wednesday = playlist(mode="normal","~/radio/playlist/wednesday.m3u")
> thursday = playlist(mode="normal","~/radio/playlist/thursday.m3u")
> friday = playlist(mode="normal","~/radio/playlist/friday.m3u")
> saturday = playlist(mode="normal","~/radio/playlist/saturday.m3u")
> sunday = playlist(mode="normal","~/radio/playlist/sunday.m3u")
>
> #Fallback playback, if for some reason the DOW can't play.
> Fall = single("~/radio/fallback.mp3")
>
> #what to play based on the DOW
> radio = fallback([ switch([
> ({ 1w },monday),
> ({ 2w },tuesday),
> ({ 3w }, wednesday),
> ({ 4w }, thursday),

I've installed LiquidSoap on to my Ubuntu workstation and this
generates
the following:
> At line 24, char 17:
> this value has type
> source(_) (inferred at line 13, char 14-37)
> but it should be a subtype of (the type of the value at line 23,
> char 29-44)
> (_*_)
Line 24, is the line that says "Fall])])" character 17 is the first ]
Any help on what the issue is, and how to fix it would be greatly
appreciated!
Chris
