Celtic Minstrel: Use syntax highlighting

Use syntax highlighting

@@ Line 8: / Line 8: @@
 Well, you could write something like this:
- [event]
+    [if]
-     name=moveto
+        [variable]
-     first_time_only=no
+            name=turn_number
-     [filter]
+            greater_than=20
-         side=1
+        [/variable]
-         x=14
+        [then]
-         y=30
+            [message]
-     [/filter]
+                speaker=narrator
-     [if]
+                message= _ "You waited too long: the flower is dead now."
-         [variable]
+            [/message]
-             name=turn_number
+        [/then]
-             less_than_equal_to=10
+    [/if]
 but this is extremely lengthy and tedious to write and maintain. Wouldn't it be awesome if we had some simpler way to test multiple conditions without having to create an entire [if] codeblock for each condition?
 Well, actually, there is an easier way to test for multiple conditions without having to wade through a quagmire of if codeblocks. This is done via the switch/case codeblock, which tests the value of a variable for multiple conditions, and determines the action performed as a result of that evaluation. The syntax of the switch/case codeblock goes thusly:
+<syntaxhighlight lang=wml>
- [switch]
+[switch]
-     variable=turn_number
+    variable=turn_number
-     [case]
+    [case]
-         value=1,2,3,4,5,6,7,8,9,10
+        value=1,2,3,4,5,6,7,8,9,10
-         # too soon
+        # too soon
-     [/case]
+    [/case]
-     [case]
+    [case]
-         value=11,12,13,14,15,16,17,18,19,20
+        value=11,12,13,14,15,16,17,18,19,20
-         # pick flower
+        # pick flower
-     [/case]
+    [/case]
-     [else]
+    [else]
-         # too late
+        # too late
-     [/else]
+    [/else]
- [/switch]

	Suppose you had a scenario in which the player must pick a flower by moving a unit to the coordinates 14,30 in order to win. But that's not all: the flower can only be picked after turn 10 and before turn 20 (so the flower can only be picked between turns 11 and 20). If the player tries to pick the flower before turn 11, the game tells him that the flower hasn't bloomed yet and that he or she needs to wait a while longer. If the player tries to pick the flower after turn 20, the game will display a message telling him or her that he or she waited too long, and now the flower is dead. How would you go about implementing this in WML?		Suppose you had a scenario in which the player must pick a flower by moving a unit to the coordinates 14,30 in order to win.
