Technical References - [listwords]

Breaks a string of text into separate words.

[listwords Words]Some Text[/listwords]

To display a list of all the separate words in a string, use a [listwords] context. You may optionally specify the delimiters defining the boundaries of words (usually spaces, commas, and periods).

Example (normally you would put the following text into a .tpl file on your server and use a web browser to link to it):
[listwords Words=This is a big long sentence]
[index]: [word]


The example above yields:

1: This
2: is
3: a
4: big
5: long
6: sentence

[listwords Words=Hello.      My name is Carl!&Delimiters= ,!]
[index]: [word]


The example above yields the following. Notice the "." at the end of "Hello." is shown as part of the word, because "." was not specified in the list of delimiters. Also notice the long run of spaces in a row is collapsed and does not appear in the word list.

1: Hello.
2: My
3: name
4: is
5: Carl

The following parameters are used in the [listwords] context:

words(Required) string of text to break up.
delimiters(Optional) List of single characters which define word boundaries. Defaults to space, comma, and dot.
tabs(Optional, Rare) Setting Tabs=T causes the list of words to break at tab boundaries only, and runs of tabs are not collapsed. This assists in parsing special formats where two tabs in a row are important and should not be skipped.

The following tags are available inside a [listwords] context:

[index]A number from 1 to the total number of words in the text indicating the word's index position in the text.
[word]Text of the word currently being displayed.
[delimiter]Text of the delimiter(s) which caused this word to break.
[break]From version 8.1, if the [listwords] context sees the [break] tag while executing, it will stop, once it finishes the current loop. Thus the [break] tag should only appear in a [showif] statement that is evaluated at the end (bottom) of the loop.
