manipulating attributes

Replacing strings in attributes

Our attribute syntax can replace strings. This syntax is part of our attribute matching (fylr 6.20 and newer):

%(key||search||replacement)s

Where search is the regexp matching what is then replaced with replacement.

The regular expressions syntax rules: https://pkg.go.dev/regexp#Regexp.ReplaceAllString.

Example: %(email||^.*=||)s, in context:

When a user logs in with attribute email equal to urn:campus:1:[email protected] and attribute mapping Target:Email %(email||^.*=||)s then his email address in fylr will be just [email protected], because the search part matches all up to the equal sign and the replacement is empty.

Multi-Value-Attributes

If there are multiple values for e.g. department, a 4th parameter can now be used to concatenate multiple values into one.

%(key||search||replacement||;)s

Example: %(dpmt||^.*=||||;)s, in context:

When a user logs in with these two attributes urn:campus:1:dpmt=marketing and urn:campus:2:dpmt=sales , the attribute mapping is done like above and in fylr the department will be

marketing;sales

pick first attribute

If an attribute is replaced like this %(mail|email)s, fylr now uses the first entry which is not empty as replacement.
