I'm still confused... do you mean in distribution? No, there is no such app for debian. There is however PharoLauncher, which is technically an app written in Pharo, that is available for Ubuntu (you could probably install the .deb in debian though). Also my DynaCASE https://dynacase.github.io/#download has linux build that should run on debian even if you don't have the required libs installed (it has them pre-downloaded, but I haven't tested it on non-debian systems).

I remembered some mails about locking up the image so you can't not access the developer environment. That precludes a lot of the Smalltalk power and message IMHO. >> There was also effort to push for NixOS iirc, but I don't know how >> that works. > I did consider to switch to NixOS recently, but then decide to settle on > Debian for all machines I have to admin... You can use Nix package manager with your current distro (debian, arch, etc.) This combination have worked for me when the distro repos lack of some package/version I care about or there are some dependency problems on them, so you can have it as a distro neutral alternative package manager that doesn't mess around with your current system without leaving the convenience your favorite tool set (apt, dpkg, pacman, builds, recipes and so on).

There is work being done on a "minimal Pharo bootstrap" which would allow you to take just the core of the platform and install whatever you need on top. But I don't know the current state. Peter

This essentially means bundling-in the VMs. If you only target Mac and/or Win, it should be easy. If you aim for linux, then good luckâ¦ I have a sometimes working setup that creates a build with the VMs and platform-specific launchers, but I don't really have time right now to clean it up and share itâ¦ but if you can wait a couple of weeks...

standalone/runtime executable

by Gour

Hello, there are some Smalltalks like Dolphin, VisualWorks..which can, afaict, create stand-alone executable for easier deployment to end users. I'm aware that Pharo probably has more important tasks to tackle first, but just curious if creating stand-alone/runtime exectuables is somewhere on its radar?
