It's a prototype of a small tool that permits you to deprecate method by annotating them with a <deprecated: ...> pragma. This pragma takes a rewrite _expression_ as argument that specifies how to rewrite the message send to the deprecated method.  If such a deprecated method is executed, a warning is thrown and a debugger opens. This debugger has a little 'Rewrite' button that permits to rewrite the sending method according to the rewrite _expression_ and then resume the execution with the new rewritten sending method :) The implementation is a proof-of-concept and is a bit hacky here and there, but it works.  Example: You have a class C with a method that you deprecate.  Its rewrite _expression_ tells that if it's executed as the result of a message send of the form:  <receiver> deprecatedMethodArg1: <arg1> arg2: <arg2>,  this message send should be rewritten to:  <receiver> replacementMethodArg1: <arg2> arg2: <arg1>.  Note you can change the order of arguments or even the receiver.   C>>deprecatedMethodArg1: o1 arg2: o2 <deprecated: '`@receiver replacementMethodArg1: `@arg2 arg2: `@arg1'>   ^ #deprecated C>>replacementMethodArg1: o1 arg2: o2 ^ #replacement C>>senderMethod ^ self deprecatedMethodArg1: 1 + 1 arg2: 2 + 2. Then if you execute C new senderMethod, and then click on the "Rewrite" button of the debugger, then sending method is rewritten to: C>>senderMethod ^ self replacementMethodArg1: 2 + 2 arg2: 1 + 1. and the result is #replacement.  The repo is on sSmalltalkHub: MCHttpRepository location: 'http://smalltalkhub.com/mc/CamilleTeruel/Deprecator/main' user: '' password: '' I hope for comments, feature suggestions, code reviews, contributors, etc :)  BTW, if you have a better name for this project let me know!  For example, I thought about Ammonite because it's an extinct animal (analogy with deprecated) and it fits the sea naming theme.
