In current Squeak 4.5 images if you add the repository MCHttpRepository location: 'http://box4.squeak.org:8888/trunk' user: 'squeak' password: 'squeak' to the Monticello Browser and then add it to the packages one is interested in (a script to add it to all is trivial), then a "Browse mc history" menu item becomes available on the class and method lists in the browser and voila, one can browse the entire class and/or method history. This feature has been missing for a long time. I really needed it this morning and wasn't quite aware that it was available already. I expect this will become a standard feature of new Squeak releases. The server can easily be duplicated on one's own machine for working detached from the internet (e.g. via http://localhost:8888/mchistory) and updates itself at regular intervals. > > Besides method versions, you can look at the git history for a class, > package or metacello project .... these are thing that would take a bit of > work to accomplish using just Monticello ... and if you were to attempt to > do it, the simplest thing to do would be to copy all of the packages into a > git repository and just use git:) Frank Shearar wrote some code that did > something along these lines a couple of years ago ... > But the work's mostly been done.

You can right-click the package and use "Demote to package with tag" (the reverse is also possible).

Hello guys how do I nest packages ? For example I currently have Ephestos Ephestos-Examples Ephestos-Object but they don't appear nested at all. What am I doing wrong ?
