This took me a while, but I found a way to create a message of the day
generator which changes the message given on how many messages you have and
what day of the month it is.
You add the messages in [[]] and the code will do the rest :D
The current 'bug' is that it will only allow you to have about 30 messages,
as it cannot display more messages of the day than there are days in the
month.
Copy/paste this Tiddler and see what message of the day you get!
<style>
.message-of-the-day {
color: red;
}
</style>
<$wikify mode="inline" name="dayofmonth_val" text=<<now DD>> >
<$set name="messages" filter="
[[Message 1]]
[[Message 2]]
[[Message 3]]
[[Message 4]]
">
<$set name="list_length" filter="[enlist<messages>count[]]">
<$set name="list_index" filter="[<dayofmonth_val>remainder<list_length>]">
<$list variable="result" filter="
[enlist<messages>nth<list_index>]">
<h1><span class="message-of-the-day">Message of the day:
<<result>></span></h1>
</$list>
</$set>
</$set>
</$set>
</$wikify>
My question here is: is there any way to do this more efficient?
In JavaScript this is the equivalent of:
var messages = ["Message 1", "Message 2", "Message 3", "Message 4"]
var result = messages[new Date().getDate() % messages.length]
//and then display the result var in anyway you see fit
