htmlbool

Purpose: Checks whether value, if interpreted as a HTML Boolean argument, is true.

Return Values: A HTML Boolean is false if:

• it is the Boolean false
• it is the null value

Example:

input:	resulting output:
<? htmlbool(true)>	true
<? htmlbool(false)>	false
<? htmlbool("true")>	true
<? htmlbool("false")>	true
<? htmlbool("Gwendolyn")>	true
<? htmlbool(" ")>	false
<? htmlbool("")>	false
<? htmlbool(null)>	false
<? htmlbool(emptytuple)>	false
<? htmlbool(5)>	true
<? htmlbool(3.1415)>	true

Tip: The htmlbool() function should prove useful when you need to redefine a HTML tag with optional arguments of Boolean type.

Example:

input:	resulting output:
<def gnarl verbose=null; if htmlbool(verbose) >We're gnarling now </if; ? "gnarl!"; /def> <gnarl> <gnarl verbose>	gnarl! We're gnarling now gnarl!
