This is the Coq development of the [Iris Project](http://iris-project.org).
The easiest way to install the correct versions of the dependencies is through
opam. Once you got opam set up, just run `make build-dep` to install the right
versions of the dependencies. When the dependencies change, just run `make
build-dep` again.
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 folder [prelude](theories/prelude) contains an extended "Standard Library"
by [Robbert Krebbers](http://robbertkrebbers.nl/thesis.html).
* 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.
Most notable here is [lib/barrier](theories/heap_lang/lib/barrier), the
implementation and proof of a barrier as described in
<http://doi.acm.org/10.1145/2818638>.
* 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-3.0.pdf).
