Metacello

Hello everyone,

I'm currently using Metacello to download my project on a new image very regularly and i'm having some trouble with this message :

You are about to load new versions of the following packages that have unsaved changes in the image:

System-SessionManager

If you continue, you will lose these changes:

Load Merge Cancel

I searched for something to prevent it but didn't find it, does someone know how I could automaticly do Load in these cases please?

I don't know the answer to your question, but to find out I would

use Tools > Finder > Source to search for "you will lose these changes",

put a haltonce in front of it and trace back through the debugger to look for WhatError was raised so that in the playground I could do [ Metacello doStuff ] on: WhatError do: [].

Now a random idea, it would be interesting if *all* dialogs raised a notification "Dialog" so you could wrap any expression as...

[ Metacello doStuff ] on: Dialog forTextLike: '*you will lose these changes*' answer: #Load.

(or a vaguely remember there is something similar already??)

Valentin,

For Pharo I use the following pattern to do "automatic loads":

[ Metacello new ... load . ]
on: Warning, MetacelloSkipDirtyPackageLoad
do: [:ex |
(ex isKindOf: MetacelloSkipDirtyPackageLoad)
ifTrue: [
"Load over dirty packages"
ex resume: false ]
ifFalse: [
Transcript cr; show: ex description.
ex resume: true ] ].
