+class LookupModule(object):
+ """
+ sequence lookup module
+
+ Used to generate some sequence of items. Takes arguments in two forms.
+
+ The simple / shortcut form is:
+
+ [start-]end[/stride][:format]
+
+ As indicated by the brackets: start, stride, and format string are all
+ optional. The format string is in the style of printf. This can be used
+ to pad with zeros, format in hexadecimal, etc. All of the numerical values
+ can be specified in octal (i.e. 0664) or hexadecimal (i.e. 0x3f8).
+ Negative numbers are not supported.
+
+ Some examples:
+
+ 5 -> ["1","2","3","4","5"]
+ 5-8 -> ["5", "6", "7", "8"]
+ 2-10/2 -> ["2", "4", "6", "8", "10"]
+ 4:host%02d -> ["host01","host02","host03","host04"]
+
+ The standard Ansible key-value form is accepted as well. For example:
+
+ start=5 end=11 stride=2 format=0x%02x -> ["0x05","0x07","0x09","0x0a"]
+
+ This format takes an alternate form of "end" called "count", which counts
+ some number from the starting value. For example:
+
+ count=5 -> ["1", "2", "3", "4", "5"]
+ start=0x0f00 count=4 format=%04x -> ["0f00", "0f01", "0f02", "0f03"]
+ start=0 count=5 stride=2 -> ["0", "2", "4", "6", "8"]
+ start=1 count=5 stride=2 -> ["1", "3", "5", "7", "9"]
+
+ The count option is mostly useful for avoiding off-by-one errors and errors
+ calculating the number of entries in a sequence when a stride is specified.
