Suggestions by New Participants

I [EJGA] performed an informal poll asking new participants what they thought of the IW and how we could improve for next year. The conclusion was that it would be good to have ready a concrete set of projects for people new to Coq and to hold a small session where each new participant gets to pick a project and a mentor. They told me they had the hardest time figuring out what to do. Other than that their experience was very positive.

Proposed Projects and Ideas

  • By EJGA:
    • New internal document format for the STM, functional-state handling. [my main focus for this IW] (CEP012)
    • Glob_constr vs constrexpr rework (upcoming CEP011).
    • Plugin linking with external dependencies.
    • Language Server Protocol support. Jupiter / IPython support.
    • Ocamlbuild for Coq
    • Code coverage with bisect_ppx.
    • SerAPI OPAM.
    • Data-centric CRUD API.
    • Auto deploy from Travis.
    • Travis Build Stages
    • Windows CI (appveyor)
    • Support for notation tables (notation scopes that can modify the parser)
    • ENotation (Extended Notation Display)
    • Scoping mechanism that is friendly to parallel processing.
    • Better benchmarking / timing for the batch compiler.
  • By MS:
    • Specification/documentation of unification
    • A big TODO list!
  • By TZ:
    • Combining focusing with { } and goal selectors (started here).
    • A way to easily give names to goals.
    • A strict mode that's satisfying for SSReflect (and for vanilla Coq as well if possible).
  • By Enrico:
    • coq-elpi (Elpi embedded in Coq) and the GPWD
  • Suggested discussion topics by Paul:
    • Resolving variable shadowing conflicts, Bug 5448
    • Unit testing to supplement end-to-end tests, including time, space usage
  • By Abhishek Anand: (the items are below are needed in the implementation of paramcoq-iff)
  • By Yves
