Prototype: canonifyuniquely(text)
Return type: string
Description: Convert an arbitrary string text
into a unique legal class name.
This function turns arbitrary text into class data, appending the
SHA-1 hash for uniqueness. It is exactly equivalent to
concat(canonify($(string)), "_", hash($(string),"sha1");
for a given
$(string)
but is much more convenient to write and remember.
A common use case is when you need unique array keys for each file in
a list, but files in the list may have the same name when
canonify
-ed.
Arguments:
text
:string
, in the range:.*
Example:
commands:
"/var/cfengine/bin/$(component)"
ifvarclass => canonifyuniquely("start_$(component)");
