Summer of Code Recap

ll likely be true till December, but I will make an effort to keep up with guile-user and be on the IRC Channel to help the daring souls who want to give this a go. My priorities will be documenting the ILs, filling in missing builtins, and improving jslink. I especially want to see basic IO and MiniKanren up and running, and for it to be convenient to use Guile's builtin libraries. Happy Hacking, Ian Price (This is a crosspost to guile-user of my blogpost [Summer of Code Recap], but please comment on this list, rather than there) [Summer of Code Recap] https://shift-reset.com/blog/2017/8/28/Summer%20of%20Code%20Recap/

Compilation to JS [Update]

Hello Guilers, I am long overdue an update on the state of affairs of guile-js (the last was at the end of June). Last time I spoke, I had completed task 1 (cps old -> cps soup), and was starting work on task 2 (port boot-9[1]). I made a lot of headway on this task, and would categorise it as "ne

I would like to be able to access Javascript functions from Scheme, possibly with a (system foreign) type API, but this is not a priority at the moment. Getting as much of Scheme as possible working is the main thing. On my list, you could put it as the unspoken 5th stage. As for residualisation,

Compilation to js [Update]

Hello guilers, I figure it's time for an update on what I've been working on for the past two weeks. I have mainly been working on updating the compiler to go from the old cps representation to the new cps-soup representation. This had a few false starts, but on the third attempt, I think the ap
