But, if we focus on the $WHERE more directly, what would you like? - A per-url/per-project SWHERE? It could make the url syntax a bit hard (there is already a $: to indicate branch and, implicitely, subdirectory inside the git repo) but there is nothing forbidding it. Something like: 'gitfiletree://github.com/dalehenrich/filetree:pharo5.0/repository/?where=/h…' (is that a correct url syntax?) - Note that I have a procedure for having the Pharo build environment integrated inside the git, if you'd like (i.e. git clone download also the build command for the right Pharo image: this is my professional setup). - A per-image $WHERE? - Reusing the Monticello default local repository directory setting? (current behavior, actually).

Is there a convenient way to control where the clone will be made in the local filesystem? Meaning: using something else than the implicit value for $WHERE: git clone $GITHUB_CLONE_URL $WHERE On 15 April 2016 at 19:08, Thierry Goubier <thierry.goubier(a)gmail.com> wrote: > Le 15/04/2016 18:49, Damien Pollet a Ã©crit : > >> On 15 April 2016 at 17:39, Thierry Goubier <thierry.goubier(a)gmail.com >> <mailto:thierry.goubier@gmail.com>> wrote: >> >> And then you can load your project with: >> >> Metacello new >> baseline: 'YourTribes'; >> repository: 'gitfiletree:// >> github.com/HappyPharoHackers/YourTribes'; >> load: #(tests) >> >> >> So this does the clone directly from github?

libusb seems to be plain C, so it would make a nice use-case for uFFI http://www.libusb.org There was an attempt at making a binding last year: https://www.mail-archive.com/pharo-users@lists.pharo.org/msg17312.html On 17 April 2016 at 12:15, Peter UhnÃ¡k <i.uhnak(a)gmail.com> wrote: > This seems relevant: > > https://medium.com/concerning-pharo/pharo-pi-9eef257b6a21#.ay5v86peq > https://www.youtube.com/watch?v=sfxFqQIuawg > > Peter > > On Sun, Apr 17, 2016 at 9:52 AM, stepharo <stepharo(a)free.fr> wrote: > >> First hello and welcome to Pharo. >> >> Second can you be clear about what you want to achieve? >> >> >> I have Squeak on a RPi but I don't know how to access any USB peripherals >>> or how to make primitives to do so.

I think everyone agrees that the platform should provide that feature, however everyone is focused on different issues, and you seem to be the first one for whom it's an itch worth scratching.
