foreach (roll option)

FOREACH Option

Introduced: Version 1.3.b46

Iterates over the contents of a string list in the format "item1, item2, item3". Can also be used easily with JSON arrays and JSON objects. String Property Lists can be processed with a couple of extra functions.

Usage

[FOREACH(var, list): body]
[FOREACH(var, list, output_separator): body]
[FOREACH(var, list, output_separator, list_separator): body]

output_separator default value is ","
list_separator default value is ",". Some examples of other useful separators: nothing "", space " " and break "<br>".

Examples

String List Example

[h: enemyList="Orcs, Goblins, Ogres, Trolls"]
[r, FOREACH(enemy, enemyList, "<br>"): "You really hate " + enemy]

JSON Array Example

[h: enemyList = json.append("","Orcs", "Goblins", "Ogres", "Trolls")]
[r, FOREACH (enemy, enemyList, "<br>"): "You really hate " + enemy]

JSON Object Example

(Note that using foreach with a JSON object will result in only the keys being returned as vars).

[h: enemyList = json.set("","Orcs", "Bob, Dave", "Goblins", "Graham", "Ogres", "Philip, Emanual", "Trolls", "Ig, Og, Ug")]
[r, FOREACH (enemy, enemyList, "<br>"): "You really hate " + enemy]

All the above will output:

You really hate Orcs
You really hate Goblins
You really hate Ogres
You really hate Trolls

Using with [code():] and output_separator

To use roll options with your FOREACH loop, you will need to use [code():] roll option. In this example I have separated the results with the string " then ".

[h: enemyList="Orcs; Goblins; Ogres; Trolls"]
[r, FOREACH(enemy, enemyList, " then ", ";"), CODE:
    {
    [r: enemy]
    }
]

output:

Orcs then Goblins then Ogres then Trolls

String Property List Example

[h: enemyStrProp = json.toStrProp(json.set("","Orcs", "Bob, Dave", "Goblins", "Graham", "Ogres", "Philip, Emanual", "Trolls", "Ig, Og, Ug"))]
[r, FOREACH(enemy, enemyStrProp, "<br>", ";"), code:
	{
	[h: enemyList = stringToList(enemy, "=")]
	[h: name = listGet(enemyList, 0)]
	[h: value = listDelete(enemyList, 0)]
	[r: "You really hate " + name + " who are " + value]
	}
]
