Storing local code in a local repository?

Paolo,

I've got some code that I'd like to pull into several
different scripts that is common between them and
would like to store them in a local directory somewhere
and do not want to store them inside the installation
tree that could (in theory) get nuked if someone
thinks only 'release' files live there.. To that end,
I'd like to tell the package loader to pull in my
local code.. Is there an easy way to get this sort
of behavior in gst?  Thx!

If not, something like the attached would work though.  The directory
would be /usr/(local/)share/smalltalk/site-packages.  You can group the
code into a .star file, or use a
/usr/(local/)share/smalltalk/site-packages/packages.xml file.

Anybody else, any interest in having this patch in 3.2.1?  It's small
and harmless enough.

Thanks,

Paolo

+1. An image-independent place for "my global stuff" makes some things easier.

Thanks Paolo!!

I'm trying to use it but am not completely sure of the format
for the packages.xml file.. Below is the current incarnation I'm
using which is not working :

<packages>

<package>
  <name>AddOns</name>
  <file>VisualWorksExtensions.st</file>
<package>

</packages>

It gives me this when I try to use the following packageLoader
line :

PackageLoader fileInPackage: #VisualWorksExtensions.


Object: Package new "<-0x53dbde8>" error: error in packages file:
unmatched end tag package
Error(Exception)>>signal (ExcHandling.st:254)

That seems to be correct for me, except that you would also need a

   <filein>VisualWorksExtensions.st</filein>

However, that wouldn't justify the failure you get from #fileInPackage:.

I'll give it a shot when I get back in the office...

Then while you're at it ...

change the line above to </package>, too.

Ok.. Fixed.. Thanks for catching that!  I was in
a hurry for my physical therapy appt.. Here's the
updated stuff :

<packages>

<package>
  <name>AddOns</name>
  <filein>VisualWorksExtensions.st</filein>
</package>

</packages>

It still isn't finding it (and yes, I did apply the earlier
patch that was sent out and did a "make install" to get it
pushed out to my baseline installation.

So, here's my directory setup :

~/gst/share/smalltalk/site-packages
~/gst/share/smalltalk/site-packages/packages.xml
~/gst/share/smalltalk/site-packages/VisualWorksExtensions.st
~/gst/share/smalltalk/packages.xml

I've added offending lines to the ~/gst/share/smalltalk/packages.xml
with no change in behavior..  Is there supposed to be a
new packages.xml in the 'site-packages' directory or
should it be part of the packages.xml one level up?

Based on the comments in PackageLoader class >>refresh,
I believe the comments should probably be updated to
indicate (if this patch is made part of the baseline)
that this extra path is also searched.

Let me know if I'm off base..

Not sure if that matters -- perhaps something
is missing?  It might be time to put some path
dumping logic in the package loader to see
what it's looking for.. I'll keep you posted!

Ok.. Had to instrument things a bit to see what
was going on.. It appears (but I've not yet
verified) that the new packages.xml in the site
directory is not being pulled in.. Nothing in that
file is getting pulled into the "root" object at
all.. I'll continue poking around.. Perhaps
something is missing that I haven't found yet.

Yes, it should be in the site-packages directory.  I'll test it in the

Paolo..

I was able to track it down.. I didn't realize (Duh!!!) that
the package name must match the name you've asked to load..
Once I did that all was good..

Below is my sample packages.xml file :

<packages>
<package>
  <name>VisualWorksExtensions</name>
  <filein>VisualWorksExtensions.st</filein>
  <file>VisualWorksExtensions.st</file>
</package>
</packages>

The following line causes this package to be loaded:

PackageLoader fileInPackage: #VisualWorksExtensions.

If we can get this included as a regular feature, that would
be great! Thanks again!
