Right now I have them on my hard drive and they are read live into Squeak when they are needed. Of course, others don't have the files at hand when working in a distributed fashion.

What are the best practices in regard of distribution/packaging as well as performance?

Due to lack of decent resource management in all Smalltalks we usually put such resources directly into methods, usually as literal array. In Aida/Web we have so called method resources and method images, in Seaside there is a FileLibrary.

Best regards Janko

I found this post from a while back. Is this still accurate? If so, what does it mean i.e. how do you put a jpeg/bmp/whatever into a method? And how to you change it back to a jpeg/bmp again?

Pretty easy. We have a tool method which reads a file and converts it into such a method. Such method just returns a file content as byte literal array. Concrete instance from DefaultWebStyle in Aida:

buttonCloseGif " '/home/mivsek/vw7.2/image/imgs/yuiForum/tab-close.gif' asFilename contentsAsMethod" ^#(71 73 70 56 57 97 13 0 13 0 135 0 0 77 87 90 115 116 115 64 255 64 133 143 143 138 145 144 175 181 179 158 190 245 192 218 249 198 221 250 204 225 250 211 229 251 217 232 252 223 236 252 228 230 224 230 240 253 236 244 253 242 247 254 249 251 254 0 0)

Hope this helps Janko

I'm sure this must be a common goal: how do package developers, who use Monticello, distribute non-code things, like files (such as image files) with their packages?

Typically, they don't. Usually packages only have code. Small things (like icons) are converted to source code. Larger media files do not normally occur in shared packages, only in app development. For apps, media files are distributed separately.

However, *if* you wanted to include arbitrary files with your code package, SAR files would be the #1 choice:

I think that's where I'll start, but I'm not quite there. This is what I did so far, cobbling together things from old posts:

stream := ReadWriteStream on: (String new). form storeOn: stream.

Is this the right direction and how do I reconstitute it?

Any object that you serialized this way can be read back with #readFrom:.

The simpler invocation for this #storeString:

s := Form fromUser storeString. "store" f := Form readFrom: s. "read"

The only stream-related fromXxx method in Form was fromBinaryStream, which gave an 'image format not recognized' error.

There are more space-efficient ways of course, e.g. you could store a GIF image base64 encoded.

What is the standard procedure for this - SAR files?

No. Application as in "Mac application" or "Windows application" or "Linux application". These just bundle a couple of files in whatever is suitable for the deployment platform - a VM, an image, and whatever other files are necessary.

Typically you just have a directory of files on your development system, managed by subversion.
