re-loading code

Greetings,

I'm looking into writing another webapp with gst/iliad.

Given that I keep my code in one file per class, and that I define
a namespace for my package via package.xml, what is the best way
to reload the code for a single class so that I don't have to
walk the "gst-remote --kill ; gst-package ; gst-remote --server"
path so often?

As an example consider the following workflow

  gst iliad/scripts/PackageBuilder.st -a package.st > package.xml
  gst-package -t ~/.st package.xml
  echo "PackageLoader fileInPackage: 'Iliad'; fileInPackage: 'App'. ObjectMemory snapshot: 'iliad.im'" | gst
  gst-remote --server --port $PRIVATE_PORT -I iliad.im 2>&1 | tee iliad.log &
  vi MyWidget.st
  ???

How do I get the updated MyWidget code into the running iliad.im
so that the next invocation actually uses the new code?

I just can't see it.

Time for a walk, obviously,
s.

Probably the best solution would be to use VisualGST, then you would also be able to debug your application easily.

I guess some users write shell scripts to make it easier the process you wrote.

You may also use Iliad Application Launcher:

But this restarts the whole application so everything is reinitialized.

If you have 1 specific class file to reload then i don't know if something like

gst-remote -e "FileStream fileIn: 'MyClass.st'"

would work?

Yep, they are! I had the "usual" counter counting to 6, then I changed
the ++ and -- methods to perform the calculations for the Collatz sequence
(n -> n/2 on --, n -> 3n+1 on ++) and ran:

gst-remote --eval "Smalltalk removeFeature: #App. PackageLoader fileInPackage: 'App'"

and, big cheer, -- led me to 3, then ++ gave me a 10.
