Common classes with JSON library representation

Hi Graham,

Associated classes are our biggest sticking point for moving to git. There are a couple solutions I’ve come up with so far:

1) Move this code to a separate Omnis library
2) Use a git submodule, which lets you merge multiple repositories together into a single working copy

We’re proceeding with option 1, mostly by moving the project-specific classes to separate libraries and leaving the rest in a single core library.

Using submodules would work in theory, but it’s more complicated. The workflow would be:

1) Create a repository for your common code
2) Include this repository in your project as a submodule
3) Export your lib to JSON
4) Copy the common classes into the directory for the common submodule
5) Commit and push your changes

When building out, you would pull remote updates, then copy the common code back into the JSON source for your library. Rebuilt the lbs from the repository and you should be good to go.

The trick is identifying which classes are common and which aren’t. This is one reason we’re just going to split up the project—this identification is easy to express by dividing classes into libraries.

I’ll make a caveat that this is all theoretical—I haven’t tried using the submodules to see if there is a better solution. If someone does find a good way to express the Omnis VCS’ concept of associations in git, please share!

We have multiple applications and an infrastructure library of common code in our Omnis VCS. This library’s classes are linked to most of our applications and this works very well in the context of building our libraries from the VCS. But I don’t immediately see an obvious way to handle this in a multiple repository setup like Git. It may just be that I don’t yet have a full understanding of Git but I would appreciate any thoughts you may have on the topic.
