This is the Coq development of the [Iris Project](http://iris-project.org).
- A development version of [std++](https://gitlab.mpi-sws.org/robbertkrebbers/coq-stdpp)
If you need to work with Coq 8.5, please check out the
[iris-3.0 branch](https://gitlab.mpi-sws.org/FP/iris-coq/tree/iris-3.0).
The easiest way to install the correct versions of the dependencies is through
opam repo add coq-released https://coq.inria.fr/opam/released
opam repo add iris-dev https://gitlab.mpi-sws.org/FP/opam-dev.git
Once you got opam set up, run `make build-dep` to install the right versions
## Updating
After doing `git pull`, the development may fail to compile because of outdated
dependencies. To fix that, please run `opam update` followed by
`make build-dep`.
Run `make -jN` to build the full development, where `N` is the number of your
CPU cores.
* The folder [algebra](theories/algebra) contains the COFE and CMRA
constructions as well as the solver for recursive domain equations.
* The folder [base_logic](theories/base_logic) defines the Iris base logic and
the primitive connectives. It also contains derived constructions that are
entirely independent of the choice of resources.
* The subfolder [lib](theories/base_logic/lib) contains some generally useful
derived constructions. Most importantly, it defines composeable
dynamic resources and ownership of them; the other constructions depend
on this setup.
* The folder [program_logic](theories/program_logic) specializes the base logic
to build Iris, the program logic. This includes weakest preconditions that
are defined for any language satisfying some generic axioms, and some derived
constructions that work for any such language.
* The folder [proofmode](theories/proofmode) contains the Iris proof mode, which
extends Coq with contexts for persistent and spatial Iris assertions. It also
contains tactics for interactive proofs in Iris. Documentation can be found in
* The folder [heap_lang](theories/heap_lang) defines the ML-like concurrent heap
language
* The subfolder [lib](theories/heap_lang/lib) contains a few derived
constructions within this language, e.g., parallel composition.
For more examples of using Iris and heap_lang, have a look at the
[Iris Examples](https://gitlab.mpi-sws.org/FP/iris-examples).
* The folder [tests](theories/tests) contains modules we use to test our
infrastructure. Users of the Iris Coq library should *not* depend on these
modules; they may change or disappear without any notice.
A LaTeX version of the core logic definitions and some derived forms is
available in [docs/iris.tex](docs/iris.tex). A compiled PDF version of this
document is [available online](http://plv.mpi-sws.org/iris/appendix-3.1.pdf).
The following is a (probably incomplete) list of case studies that use Iris, and
that should be compatible with this version:
* [Iris Examples](https://gitlab.mpi-sws.org/FP/iris-examples) is where we
collect miscellaneous case studies that do not have their own repository.
* [LambdaRust](https://gitlab.mpi-sws.org/FP/LambdaRust-coq/) is a Coq
formalization of the core Rust type system.
* [Iris Atomic](https://gitlab.mpi-sws.org/FP/iris-atomic/) is an experimental
formalization of logically atomic triples in Iris.
## For Developers: How to update the std++ dependency
* Do the change in std++, push it.
* Wait for CI to publish a new std++ version on the opam archive, then run
`opam update iris-dev`.
* In Iris, change the `opam` file to depend on the new version.
* Run `make build-dep` (in Iris) to install the new version of std++.
You may have to do `make clean` as Coq will likely complain about .vo file
