Chunk browser question

Hello all,

Is there a simple way to use Ian's CB to preview the contents of a Dolphin
patch?  My goal is to preview the changes, in particular #queryPort and any
related changes.  I obtained the patches with LiveUpdate's open... command,
and saved the resulting text as a .st file.  The CB's view of the file is
analogous to a structured storage file - most of the payload is contained in
a single chunk called "evaluation".

So far, I have used the CB to open the patch file, copy the evaluation
chunk, paste that into a workspace and then save a new .st file that
_appears_ to be a valid patch file.  Is there a better way?

Have a good one,

Bill

Basically you need to skip the secure header chunks and then extract the
patches from the payload chunk. Something like the following should do it:

    f := FileStream read: path, 'pl3.st'.
    c := ChunkSourceFiler on: f.
    6 timesRepeat: [c nextChunk].
    (FileStream write: path, 'patch level 3.st') nextPutAll: c nextChunk;
close.
    f close.

There is now - thanks for the suggestion :-)

A replacement ChunkBrowser that has an "Open Patch File" option on the
Files menu that, surprise surprise, opens a saved Dolphin patch file and
displays all the hunks therein.
