Hello, This announcement is for those who develop in latest Pharo 3 and are curious about a more advanced way of recording code changes than the current ".changes" mechanism. In particular, it should be useful when your image crashes and you want to recover lost changes. Some of you may have seen a demo at ESUG. Epicea is far from stable or beautiful [1], but you can try it and any feedback or collaboration would be welcome. Download it You can download an image from Jenkins ci build [2]. Also you can load it with: Gofer it smalltalkhubUser: 'MartinDias' project: 'Epicea'; loadStable. Use it Record To start recording, do: EpLog current enable. After that, any change you do in the image (e.g. creating a class, modifying a method) will be written in .ombu files in the current working directory. In fact, not only code changes are recorded but also other events like snapshots, test runs, Monticello loading and saving, etc. Browse You have two ways of browsing the recorded stuff: To browse the current log, do: EpLog current browse. To browse any .ombu file in your disk, you can simply drag&drop it into the image (from Finder in Mac). Best regards, MartÃn [1]: It's needed to: - implement export/import use case (an alternative to .cs files) - rethink some concepts - unit tests - write more comments - a lot more [2]: https://ci.inria.fr/pharo-contribution/job/Epicea/PHARO=30,VERSION=stable,VM...
Hey Martin, Epicea looks really cool. I can't wait to have it in Pharo 3.0. Some questions however: - Can we use Epicea to recover lost changes ? I mean let's say you have an image with a lot of work inside, then it crashes before you save the image. How do you then recover lost changes with Epicea (as now we do worldMenu>tools>recover lost changes...)? - Moreover, in the case the image has a lot of work inside and crashes but you cannot reopen it (the saved image is corrupted too), what can you do with Epicea ? Usually I take the changes file and put it in a fresh image to restore my work. Does Epicea save data into an external file too ? If not how to recover data from a corrupted image ? Thanks for your future answers, Best, 2013/10/23 Martin Dias <tinchodias@gmail.com>

It seams data are written in a .ombu file "will be written in .ombu files " So I guess the work remain the same here :) Ben On 23 Oct 2013, at 16:10, Clément Bera <bera.clement@gmail.com> wrote:

:p thanks! a bit early to say but why not in the future.

Yes, it's the main use case. For the moment, to browse you have to drag the .ombu file and drop it into the image. You will recognize the .ombu file because they're prefixed as your .image file name. When the logging is enabled, each time you open an image (i.e. a session starts), a new file is created but a new suffix.
- Moreover, in the case the image has a lot of work inside and crashes but you cannot reopen it (the saved image is corrupted too), what can you do with Epicea ? Usually I take the changes file and put it in a fresh image to restore my work. Does Epicea save data into an external file too ? If not how to recover data from a corrupted image ?
Yes, the same as for the previous question.
Thanks for your future answers,
