List of POPL 2017 papers with crowd-sourced preprint links has a list of POPL 2017 papers with crowd-sourced links to the preprints. The deadline for camera-ready version (a version provided by the researchers that takes reviewers' comment into account) is only on November 7th, so one should expect more preprints to be available after that.

Feel free to mention any paper that catches your interest. If you are very curious in a particular work that does not have an online preprint, sending an email to the authors to ask them whether they plan to have a preprint accessible online can help a lot.

    Thanks, Hazelnut looks interesting, but I still have trouble figuring out how to turn theory into profit.

    The biggest win is that

    ...bidirectionality gives them a really elegant/pretty story for holes nested in holes. This lets them evade one of the traditional pitfalls of syntax editors, namely that programs must be written in a top-down style.

    Eg, if you are in a hole context where (say) a string is expected, and you write the number 5, their structure editor doesn't ban this. Instead, it puts the 5 inside a nested hole, so that you can later refine the bit of program that eats the 5 to make the string.

    You can download a (very) toy implementation on Github. It's a very direct implementation of the theory, so it feels like someone pasted an HTML5 interface over the Cornell Program Synthesizer, but it's enough to get the ideas in the paper across.

    You can play with our reference implementation here. (The preprint+Agda mechanization is also linked from there)
