Center hyperedge (induced by source paper "pide as front end technology for coq"):
  Abstract: Isabelle/PIDE is the current Prover IDE technology for Isabelle. It has been developed in ML and Scala in the past 4-5 years for this particular proof assistant, but with an open mind towards other systems. PIDE is based on an asynchronous document model, where the prover receives edits continuously and updates its internal state accordingly. The interpretation of edits and the policies for proof document processing are determined by the prover. The editor front-end merely takes care of visual rendering of formal document content. #R##N#Here we report on an experiment to connect Coq to the PIDE infrastructure of Isabelle. This requires to re-implement the core PIDE protocol layer of Isabelle/ML in OCaml. The payload for semantic processing of proof document content is restricted to lexical analysis in the sense of existing CoqIde functionality. This is sufficient as proof-of-concept for PIDE connectivity. Actual proof processing is then a matter of improving Coq towards timeless and stateless proof processing, independently of PIDE technicalities. The implementation worked out smoothly and required minimal changes to the refined PIDE architecture of Isabelle2013. #R##N#This experiment substantiates PIDE as general approach to prover interaction. It illustrates how other provers of the greater ITP family can participate by following similar reforms of the classic TTY loop as was done for Isabelle in the past few years.
