LiveCode Source Control

Question

Anyone out there using LiveCode in a multi developer project?

Either way, can someone recommend a good source control system / plugin to use?

We've looked at MagicCarpet but since it is no longer developed we wish to use something else.

Thanks

Answer 1

Yes, our team has been using LiveCode with multiple developers. Since the Livecode community is still young, acquiring good source control tools can be a challenge. Our solution has been to break code into modules (stack files). When there are updates to merge into the main codebase, we clone our existing codebase, and merge code changes manually using line by line compare in a text editor. This is not a fun process, but is much less painful than it sounds.

If I were to redesign the system, we would simply use Git (Github.com etc.). There is no reason this would not work with Livecode stacks.

Answer 2

I'm working on a solution to this problem by exporting the stack file as a structured directory of script, json and image files which will diff and merge nicely in most VCS. It is not yet available but the intention is it will be open source. My goal is to demonstrate it at the RunRevLive conference in May.

Here's the repo for lcVCS https://github.com/montegoulding/lcVCS

Answer 3

I have put a git library stack on revOnline (libVersionControl) that exports to structured xml files that git can handle. It works as far as it goes, but I have hopes that Monte's solution will supersede this effort.

We use LiveCode in a small team with Subversion.

We don't have a perfect solution, but it is very lightweight; we all use a custom extension to the standard toolbar, which among other things has a 'save+backup' button. When we started using it with Subversion, we added code to this button which saves an XML sidecar file for the stack. The file contains all the scripts, custom properties, and optionally fields (controlled by user property in each stack). In our case almost all of our work is in scripts, so this works for us.

The effect is that each time we commit to SVN, we're always committing two files, the LiveCode stack and the accompanying sidecar file - the latter works fine for diffing etc.

Where this lets us down is that we don't have any solution for merging. If we were working on larger systems more actively, we'd also modify I expect look to modify the sidecar format into a complete folder of files. For now however this makes the situation workable (and it takes no noticeable time to generate the sidecar file).

Happy to share code if that was useful.

Answer 5

I know of a tool thats being worked on that is going to really help in this regard. When he showed it to me it looked very functional already. But I'm not sure when he will share it with the community.

So the point is, its just a matter of time before people's stuff comes together to make a turn key solution for this.
