Actually it looks like that extra 1.5mb is not worth having as It seems that something does end up using the class organisation and so it must recompute when the image is launched. Tim > On 17 Aug 2017, at 13:07, Tim Mackinnon wrote: > > Just thought I would report back a

Hi, tracing through your changes - it looks like: Smalltalk cleanUp: true except: #() confirming: false. Takes care of all the non-unicode changes you proposed (and it seems like its a known cleanup protocol). I wonder if the Unicode change is worth it/risky as many web based services I might

Yes - that is a fair warning - I guess I’m looking for ways to reset Monticello/metocello artefacts and caching (maybe I should ask Dale for some tips - as I find the Monticello/metacello packages quite big and difficult to follow, and there are no class comments to give you any pointers). I’m

Be careful because some of those aggressive cleanups may turn some parts of your image unstable. For example: This is dangerous: MCMethodDefinition allInstances do: [:each | each become: String new ]. MCClassDefinition allInstances do: [:each | each become: String new ]. MCVersionInfo

Actually it happens first that monticello is "nicely" coupled with the changeset system and logs all the source code loaded in change sets :D :/ ¬¬. Also, the first two strings in terms of size are related to unicode tables (we should put them in files instead of in the image and load them on
