Module:LeftAlignedList

Module:LeftAlignedList

Utility module to support Template:LeftAlignedList by converting comma-separated strings into bullet lists.

This module provides the following function(s):

• main - Converts a comma-separated string into a wikitext bullet list. Each comma-delimited value becomes its own `*` list item, with surrounding whitespace trimmed.

Usage

Core functionality

{{#invoke:LeftAlignedList|main|Item 1, Item 2, Item 3}}

Output:

* Item 1
* Item 2
* Item 3

Convert each item into wikilink

{{#invoke:LeftAlignedList|main|Item 1, Item 2, Item 3|link=true}}

Output:

* [[Item 1]]
* [[Item 2]]
* [[Item 3]]

Parameters

main

1

string

A comma-separated string containing the items to convert into a bullet list.

link (optional)

boolean

If specified with a truthy value, each item will be wrapped in double square brackets, rendering it as a wikilink.

Valid values:

true

yes

1

Notes

main

• Empty items are ignored (e.g. `A,,B` becomes `A` and `B`).
• If the input contains no commas, it will still be returned as a bullet list with a single `*` item.
