Python CFFI bindings to sysrepo.
pip install sysrepo
This assumes that libsysrepo.so
is installed on the system and that
sysrepo.h
is available in the system include dirs.
Since sysrepo depends on libyang, the latter needs to be installed on the system as well.
You need the following system dependencies installed:
- Python development headers
- GCC
- Python CFFI module
On a Debian/Ubuntu system:
apt-get install python3-dev gcc python3-cffi
If sysrepo headers and libraries are installed in a non-standard location, you
can export the SYSREPO_HEADERS
and SYSREPO_LIBRARIES
variables.
Additionally, for finer control, you may use SYSREPO_EXTRA_CFLAGS
and
SYSREPO_EXTRA_LDFLAGS
:
SYSREPO_HEADERS=/home/build/opt/sr/include \
SYSREPO_LIBRARIES=/home/build/opt/sr/lib \
SYSREPO_EXTRA_CFLAGS="-O3" \
SYSREPO_EXTRA_LDFLAGS="-Wl,-rpath=/opt/sr/lib" \
pip install sysrepo
Note
This Python package depends on libyang CFFI bindings, if it is not installed yet and libyang headers and libraries are also installed in a non-standard location, you must export additional variables. See the "Compilation Flags" section here: https://pypi.org/project/libyang/.

This is an open source project and all contributions are welcome.
Please create new issues for any bug you discover at https://github.com/sysrepo/sysrepo-python/issues/new. It is not necessary to file a bug if you are preparing a patch.
Here are the steps for submitting a change in the code base:
Fork the repository: https://github.com/sysrepo/sysrepo-python/fork
Clone your own fork into your development machine:
git clone https://github.com/<you>/libyang-python
Create a new branch named after what your are working on:
git checkout -b my-topic
Edit the code and call
make format
to ensure your modifications comply with the coding style.Your contribution must be licensed under the BSD 3-Clause "New" or "Revised" License . At least one copyright notice is expected in new files.
If you are adding a new feature or fixing a bug, please consider adding or updating unit tests.
Before creating commits, run
make lint
andmake tests
to check if your changes do not break anything. You can also runmake
which will run both.Create commits by following these simple guidelines:
Solve only one problem per commit.
Use a short (less than 72 characters) title on the first line followed by an blank line and a more thorough description body.
Wrap the body of the commit message should be wrapped at 72 characters too unless it breaks long URLs or code examples.
If the commit fixes a Github issue, include the following line:
Fixes: #NNNN
Inspirations:
https://chris.beams.io/posts/git-commit/ https://wiki.openstack.org/wiki/GitCommitMessages
Push your topic branch in your forked repository:
git push origin my-topic
You should get a message from Github explaining how to create a new pull request.
Wait for a reviewer to merge your work. If minor adjustments are requested, use
git commit --fixup $sha1
to make it obvious what commit you are adjusting. If bigger changes are needed, make them in new separate commits. Once the reviewer is happy, please usegit rebase --autosquash
to amend the commits with their small fixups (if any), andgit push --force
on your topic branch.
Thank you in advance for your contributions!
