It definitely interests me. > Documentation is still sparse for tODE, but all of the command line commands have man pages:) I plan to write some posts on this list about the workflows, structure and functionality currently used in tODE and GsDevKit_home that will cover the larger points. In addition to the git support from within the "Project Browser": project browser git menu I have a smalltalk API for calling the git command line and I use that for implementing all of the git functionality (so there's no Windows mapping - but then the GemStone server doesn't run on Windows). In the code browser, you can get git history on a project, package, class and method level. I've also built a `git mergetool` to a git-level merge from within the Smalltalk dev environment. When you get the time let me know and I can give you more information ... Dale

if it is that, is a known bugâ¦ just save&quit and reopen (I will find the bug eventually, but is complicated).

Thanks for the interest Sven! > > How easy is it to load tODE in a current (4.x 5.x) Pharo image ? I assume there is a Metacello configuration ;-) Is it possible to experiment with it in Pharo, independent from Gemstone ? I did not see it in the Catalog Browser (our current point & click installer). As it stands right now, tODE is not loadable/functional in Pharo ... In my earlier tODE work, I implemented it in both Pharo and GemStone, but this current version of tODE started out life as a remote development environment for GemStone with emphasis on the remote aspect --- so a significant chunk of tODE is devoted to managing windows running in a Pharo image while executing all of the functionality in GemStone ... With that said, I have architected tODE to isolate the basic tool functionality from the GUI/command line and the model has evolved to the point where all tools (both GUI and CommandLine --- yes there are bash-like command mappings for all GUI functionality) share the same basic algorithms behind a smalltalk api --- so developers can easily tap into the functionality behind every GUI window/tODE shell command. If you want to experiment today, you'll have to do that in GemStone with GsDevKit_home[1] [1] https://github.com/GsDevKit/GsDevKit_home > > Making tODE easily loadable would, IMHO, be the first step to a broader adaption of your work (in one form or another). The next step would be a getting started tutorial. > Haha, I am bandwidth limited myself and as tODE and GsDevKit_home are still works in progress (quite functional, but still evolving:) I do not have the cycles to worry about getting tODE to work in Pharo.... I've got my hands full with tODE and GemStone ... Sooo at the end of the day, I would be willing to work with folks in porting the interesting bits of tODE to Pharo, but "interesting bits" is in the eye of the beholder and in this case I am not the beholder ... I think it's more important to share some of the structural (on disk) and architectural (in-image) lessons that I've learned about working with tODE, git and Metacello ... For example a "Project Browser" is a critical tool that needs to exist ... I've started sharing some of the implementation details with Thierry already ... I would recommend that the "project browser" be implemented in a set of classes totally independent of the GUI --- let the menu items and functionality expressed in the "Project Browser" drive a smalltalk api that can be called from a variety endpoints beyond the initial "project browser" implementation (take the approach that developers will want to incorporate all of the functionality in the "project browser" in their own GT tool) so every menu item and every meaningful click should call this "smalltalk api) and very little "business logic" should be present in the GUI itself ... The details of the functionality of the tool will depend upon the set of work flows that will be supported and on this point I do have 4 years of experience to bring to bear on this matter, but I want to share information and opinions rather than dictate functionality: that is the job of the tool builder:) Since there seems to be interest, I intend to write a series of posts describing the disk architecture and workflows used in GsDevKit_home for incorporating git (or any other disk-based SCM) into smalltalk dev environments ...
