Hello,
Just returning to this topic.
As most of the metrics are not described at the Fame level we are losing
this information when we export a model to MSE in Moose. We know that most
of the metrics can be recalculated in the model, but in some cases they
cannot.
For example, when exporting in Moose a Java (VerveineJ) model we lose the
metrics cyclomaticComplexity (CYCLO) and numberOfStatements (NOS) and we
cannot recalculate them.
So, to avoid it, I changed some metrics (some I think are important, but we
can change them if we integrate in Moose) to be described at the Fame level
and like that we can export them into a MSE. In this case, as the we could
have a huge MSE, I implemented a filter and you can select the metrics to be
exported through a wizard. It solves, for example, the lose of information
with VerveineJ if you decide to export CYCLO and NOS.
To try you can run the script below and the right-click in a MooseModel and:
Import / Export -> Export model to MSE with metrics. Use the last version of
Merlin.
Gofer new
squeaksource: 'FameImportExportEx';
package: 'Fame-ImportExport-Extensions';
package: 'Fame-ImportExport-Extensions-MSE';
load.
regards,

At one point
metrics were described in the meta-model but then MSE files
were very large, slow
to export (because you have to compute all metrics),
and slow to load (this was a long time ago). We decided to remove them from
the Smalltalk MSE export (although the MSE importer can still handle metrics
and other data, like for example when importing from infusion/verveinej).
but even in Smalltalk you need to keep loc
Now is the interface to select what to
export/import functional?
I do not know but this is something you we should definitively do
: select what to save
: select the format
-> tab separated, mse, xml
That would be the way to go. Then describe
metrics as part of a Fame
package 'Metrics', then we can select group of
data by package. I would
still like to be able to not export metrics in the MSE file.
