Contributing to the Iris Coq Development
How to submit a merge request
To contribute code, you need an MPI-SWS GitLab account (use the "Register" tab). Please send your MPI-SWS GitLab username to Ralf Jung to enable personal projects for your account. Then you can fork the Iris git repository, make your changes in your fork, and create a merge request.
Please do not use the master branch of your fork, that might confuse CI. Use a feature branch instead.
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 domake clean
as Coq will likely complain about .vo file mismatches.
How to write/update test cases
The files in tests/
are test cases. Each of the .v
files comes with a
matching .ref
file containing the expected output of coqc
. Adding Show.
in selected places in the proofs makes coqc
print the current goal state.
This is used to make sure the proof mode prints goals and reduces terms the way
we expect it to. You can run MAKE_REF=1 make
to re-generate all the .ref
files;
this is useful after adding or removing Show.
from a test. If you do this,
make sure to check the diff for any unexpected changes in the output!
Some test cases have per-Coq-version .ref
files (e.g., atomic.8.8.ref
is a
Coq-8.8-specific .ref
file). If you change one of these, remember to update
all the .ref
files.
