Understanding Spotter?

by stepharo

Hi Is there a help a student or idiot like me can read about how to find information with Spotter? For example We with luc wanted to find all the senders of variableSubclass: we tried # #senders and more... but gave up. Yesterday I wanted to find all the user of <menu> May be I missed an obvious help that will enlighten me? I hope. Now without such help how can we expect students or users to discover the way we should use the tools? We were planning to do a video to explain Spotter but I'm slowly thinking to discard this video because we do not know. Stef

Hi, i would like to have the GTDebugger in the near future. Great job and thanks! I like the Esteban built instead of the original one and i agree with stef on removing _stack and _thisContext from top and the bytecode view. Aim to simplicity must be a top priority and if anybody needs something more specific can change it easily (its moldable!)

Re: [Pharo-dev] Help with FFI crash in latest Spur (only in Linux)

by Eliot Miranda

Mariano, if you followed the approach I described recently you wouldn't be having these problems. Instead, the system would be generating the information you need to know about sizes for you automatically. Eventually you're going to have to grasp the nettle of how to import platform-specific information such as structure sizes, values of $defines, layout of structs, etc, etc. I presented a straightforward approach but you've yet to comment on it.
