We would love for you to contribute to the NMODL Framework and help make it better than it is today. As a contributor, here are the guidelines we would like you to follow:
Please do not hesitate to raise an issue on github project page.
If you find a bug in the source code, you can help us by submitting an issue to our GitHub Repository. Even better, you can submit a Pull Request with a fix.
You can request a new feature by submitting an issue to our GitHub Repository. If you would like to implement a new feature, please submit an issue with a proposal for your work first, to be sure that we can use it.
Please consider what kind of change it is:
- For a Major Feature, first open an issue and outline your proposal so that it can be discussed. This will also allow us to better coordinate our efforts, prevent duplication of work, and help you to craft the change so that it is successfully accepted into the project.
- Small Features can be crafted and directly submitted as a Pull Request.
Before you submit an issue, please search the issue tracker, maybe an issue for your problem already exists and the discussion might inform you of workarounds readily available.
We want to fix all the issues as soon as possible, but before fixing a bug we need to reproduce and confirm it. In order to reproduce bugs we will need as much information as possible, and preferably a sample MOD file or Python example.
When you wish to contribute to the code base, please consider the following guidelines:
-
Make a fork of this repository.
-
Make your changes in your fork, in a new git branch:
git checkout -b my-fix-branch master
-
Create your patch, including appropriate test cases.
-
Enable
NMODL_TEST_FORMATTING
CMake variable to ensure that your change follows the coding conventions of this project when running the tests. The formatting utility can also be used directly:- to format CMake and C++ files:
cmake/hpc-coding-conventions/bin/format
- to format only the C++ files:
cmake/hpc-coding-conventions/bin/format --lang c++
- to format a subset of files or directories:
cmake/hpc-coding-conventions/bin/format src/codegen/ src/main.cpp
- to check the formatting of CMake files:
cmake/hpc-coding-conventions/bin/format --dry-run --lang cmake
- to format CMake and C++ files:
-
Run the full test suite, and ensure that all tests pass.
-
Commit your changes using a descriptive commit message.
git commit -a
-
Push your branch to GitHub:
git push origin my-fix-branch
-
In GitHub, send a Pull Request to the
master
branch of the upstream repository of the relevant component. -
If we suggest changes then:
-
Make the required updates.
-
Re-run the test suites to ensure tests are still passing.
-
Rebase your branch and force push to your GitHub repository (this will update your Pull Request):
git rebase master -i git push -f
-
That’s it! Thank you for your contribution!
After your pull request is merged, you can safely delete your branch and pull the changes from the main (upstream) repository:
-
Delete the remote branch on GitHub either through the GitHub web UI or your local shell as follows:
git push origin --delete my-fix-branch
-
Check out the master branch:
git checkout master -f
-
Delete the local branch:
git branch -D my-fix-branch
-
Update your master with the latest upstream version:
git pull --ff upstream master
If you are developing NMODL, make sure to enable both NMODL_FORMATTING
and NMODL_PRECOMMIT
CMake variables to ensure that your contributions follow the coding conventions of this project:
cmake -DNMODL_FORMATTING:BOOL=ON -DNMODL_PRECOMMIT:BOOL=ON <path>
The first variable provides the following additional targets to format C, C++, and CMake files:
make clang-format cmake-format
The second option activates Git hooks that will discard commits that do not comply with coding conventions of this project. These 2 CMake variables require additional utilities:
clang-format can be installed on Linux thanks
to LLVM apt page. On MacOS, you can simply install llvm with brew:
brew install llvm
.
cmake-format and pre-commit utilities can be installed with pip.
You may run the Python test-suites if your contribution has an impact on the Python API:
- setup a sandbox environment with either virtualenv,
pyenv, or pipenv. For instance with virtualenv:
python -m venv .venv && source .venv/bin/activate
- build the Python package with the command:
python setup.py build
- install pytest Python package:
pip install pytest
- execute the unit-tests:
pytest
If you want to test for memory leaks, do :
valgrind --leak-check=full --track-origins=yes ./bin/nmodl_lexer
Or using CTest as:
ctest -T memcheck
If you want to enable clang-tidy
checks with CMake, make sure to have CMake >= 3.15
and use following cmake option:
cmake .. -DENABLE_CLANG_TIDY=ON
