That is very cool. Any intentions to do mobile?

I saw a demo of it two weeks ago. This is really good stuff! Cruiser is about turning a Pharo app as a stand-alone application, as an .exe file from a user perspective, without knowing there is Pharo underneath.

[ANN] Cruiser: A Pharo app packager

by Vincent.Blondeau＠lamresearch.com

Hi Pharoers! I pleased to announce you the first release of Cruiser: a tool to package your Pharo applications. The idea is to quickly convert an application from a development environment to a production one. A production environment means: * No writing on the disk * No access to the source code (by the shortcuts, debugger,...) * No error displaying on the interface * The only thing accessible is the user application I let you discover it on: https://github.com/VincentBlondeau/Cruiser [cid:image002.png@01D3B6D0.B0BAA0B0] Do not hesitate to ask me questions or contribute to improve it!

Maybe there's a better source management system out there, but for me git is much better than any of the alternatives I've used (rcs, svn, vcs and a couple I've forgotten (cms?)). > 1.

Incredible how simple thinks does > not work simply with git. I consider myself far from a git expert, so take the following with a grain of salt... You haven't given much detail, but when you have a clone think of the branches that are upstream as being "read only" (typically master and development). They should only ever be modified by merging in the branch from upstream. If you're writing (committing) to your clone, it should always be in a separate branch. When updating, e.g. master, from upstream, get in to the habit of enforcing fast-foward only e.g.: git checkout master git fetch --prune upstream git merge --ff-only upstream/master git push It's more steps, but will ensure you don't get in to the problem you describe above. git pull will do a merge if necessary, making future updates hard / impossible. > 2.

I agree that it would be nice if it was possible to avoid downloading the files each time, and also possible separate the process in to a number of stages, and restart from a nominated stage. Maybe the stages could be: 1. Download all requirements (stable vm (6.0), target vm (7.0), bootstrapImage.zip and anything else I've forgotten). 2. The build steps in bootstrap.sh. 3. The build steps in build.sh There could be a "clean" option that would be called as part of the CI process to ensure that everything is always up to date. Esteban and co.: How open are you to refactoring the scripts to support this? Or is there something I don't understand that means it doesn't make sense? Cheers, Alistair

I used the one click image (installing applications on those windows seven virtualized OS is not possible without admin right which I havenât).

Unfortunately Windows lacks a standard repository with a broad range of open source packages installable with a single command. Here it makes more sense to auto-install some package.

I guess its unit tests and manual effort. The next question is whether its worth the effort. For a given production environment, you might take a hit every couple of years when you move distro-versions. For a more turnkey system suiting a broader range of new users, maybe downloading a particular version of libsodium from the project site is a better option. Checking just now i see the Ubuntu 16.04 LTS libsodium library is version 1.0.8... https://launchpad.net/ubuntu/xenial/+package/libsodium18 which actually is unsupported... https://download.libsodium.org/libsodium/releases/old/unsupported/ so perhaps downloading from the project site is a better option. cheers -ben P.S.
