Before this fix, the LLVM Python bindings on SVN trunk always fail with: Exception: LLVM shared library not found! since it's still looking for a library named "LLVM-3.1svn". Besides updating the LLVM version in the library name, this patch also changes llvm.get_library() to make it possible to run the unit tests without installing the LLVM shared library into a default linker search path. e.g. after this patch, running the llvm/python unit tests with: LD_LIBRARY_PATH=../build/Debug+Asserts/lib nosetests -v bindings/python/llvm/tests/ would work on Linux. Patch from Scott Tsai (with some minor modifications) Patch also acked by Gregory Szorc git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@168390 91177308-0d34-0410-b5e6-96231b3b80d8 |

This directory contains Python bindings for LLVM's C library. The bindings are currently a work in progress and are far from complete. Use at your own risk. Developer Info ============== The single Python package is "llvm." Modules inside this package roughly follow the names of the modules/headers defined by LLVM's C API. Testing ------- All test code is location in llvm/tests. Tests are written as classes which inherit from llvm.tests.base.TestBase, which is a convenience base class that provides common functionality. Tests can be executed by installing nose: pip install nosetests Then by running nosetests: nosetests To see more output: nosetests -v To step into the Python debugger while running a test, add the following to your test at the point you wish to enter the debugger: import pdb; pdb.set_trace() Then run nosetests: nosetests -s -v You should strive for high code coverage. To see current coverage: pip install coverage nosetests --with-coverage --cover-html Then open cover/index.html in your browser of choice to see the code coverage. Style Convention ---------------- All code should pass PyFlakes. First, install PyFlakes: pip install pyflakes Then at any time run it to see a report: pyflakes . Eventually we'll provide a Pylint config file. In the meantime, install Pylint: pip install pylint And run: pylint llvm And try to keep the number of violations to a minimum.
