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
Ralf Jung's avatar

17
opam.  You will need the Coq and Iris opam repositories:

19

    opam repo add coq-released https://coq.inria.fr/opam/released

20
    opam repo add iris-dev https://gitlab.mpi-sws.org/FP/opam-dev.git
21

Once you got opam set up, run `make build-dep` to install the right versions

of the dependencies.

## 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After doing `git pull`, the development may fail to compile because of outdated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`.

* 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
41
  entirely independent of the choice of resources.

42
  * The subfolder [lib](theories/base_logic/lib) contains some generally useful

45
    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

49
  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

53
  [ProofMode.md](ProofMode.md).

* 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
68
available in [docs/iris.tex](docs/iris.tex).  A compiled PDF version of this

## 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.
* In Iris, change opam 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
  mismatches.
