Is there an example of how to construct a multi-part (text/plain and text/html) MIME email message in Pharo/Seaside anywhere? Thanks, TF

[Pharo-project] How to copy a CompiledMethod?
by Gabriel HernÃ¡n Barbuto Nov. 26, 2010

Nov. 26, 2010

Hi I am trying to make a complete duplicate of a CompiledMethod. I started with CompiledMethod>>#copyWithTrailerBytes: but I think that this way still leaves some things to copy. It duplicates all the literals, but I think that it doesn't duplicate a Pragma if for example, the method has one. Is there a proper way to completely make deep copy of a CompiledMethod? I mean, without writing my own. If there is a way to do it, I don't want to duplicate it. Thanks in advance. Gabriel

gabriel veryDeepCopy should be replaced by copy and postCopy. So could you publish a version of postCopy with a couple of tests? Because this would be good to make progress from this side.

I would prefer to make sure that we ensure that people can load file with underscores. And one day we discard that.

Hi Lukas, >In Pharo 1.2 we hopefully remove the option (underscore assignments) >to get rid of them for all and forever. You wont get rid of them just by removing the option. :( There is a lot of "legacy" code out there that is not converted and will then not be loadable in Pharo >= 1.2 or greater. Keeping the option would allow to load this code and convert it to standard assignment in the future. Otherwise one has to use Squeak or Pharo < 1.2 to convert before using it in recent images. On the other side we havent cared on backward compatibily too much anyway (yet) ... Bye T. -- GMX DSL Doppel-Flat ab 19,99 €/mtl.!
