Hi all I want something similar in the spirit to PythonDocTest https://docs.python.org/2/library/doctest.html I'm talking about basename "Returns the base of the basename, i.e. /foo/gloops.taz basename is 'gloops.taz' / basename is '/'" Pragmas do not work well i.e., basename "Returns the base of the basename" <expr: '''/foo/gloops.taz'' asFileReference basename' result: 'gloops.taz'> We should invent a syntax to be put inside comments and that we can easily parse because we need to improve the use and discovery of the library. I was thinking about basename "Returns the base of the basename" " '/foo/gloops.taz' asFileReference basename >>> 'gloops.taz' " Do you have any idea? I cannot not do anything and just complain that our methods are not that well documented. We as a community should take this and build an super cool system. I tried and defined >>> on Object to see if it works! Object >>> aResultingObject "If the method comment contains >>> then it is a pharo documentated test. We can check that it is true." " '/foo/gloops.taz' asFileReference basename >>> 'gloops.taz' " ^ self = aResultingObject Stef
