Function Documentation

boolean_or()

function boolean_or	(	v	,
		d
	)

Return given value, if it is Boolean, else return a secondary value, if not.

Parameters

v	<value> A primary value.
d	<value> A secondary value.

Returns

<value> v when it is Boolean and d otherwise.

defined_or()

function defined_or	(	v	,
		d
	)

Return given value, if defined, or a secondary value, if primary is not defined.

Parameters

v	<value> A primary value.
d	<value> A secondary value.

Returns

<value> v when it is defined and d otherwise.

The value d is returned only when v is equal to undef.

Here is the caller graph for this function:

index_c()

function index_c	(	i	,
		l	,
		f	= 0
	)

Return a circular index position.

Parameters

i	<integer> A integer position.
l	<integer> The range length.
f	<integer> The starting index position.

Returns

<integer> The index position mapped into a circular list within the range [f : l+f-1].

list_or()

function list_or	(	v	,
		d
	)

Return given value, if it is a list, else return a secondary value, if not.

Parameters

v	<value> A primary value.
d	<value> A secondary value.

Returns

<value> v when it is a list and d otherwise.

number_or()

function number_or	(	v	,
		d
	)

Return given value, if it is a number, else return a secondary value, if not.

Parameters

v	<value> A primary value.
d	<value> A secondary value.

Returns

<value> v when it is a number and d otherwise.

string_or()

function string_or	(	v	,
		d
	)

Return given value, if it is a string, else return a secondary value, if not.

Parameters

v	<value> A primary value.
d	<value> A secondary value.

Returns

<value> v when it is a string and d otherwise.
