Gregory Szorc | 61e22cd | 2012-03-10 04:41:24 +0000 | [diff] [blame] | 1 | This directory contains Python bindings for LLVM's C library. |
| 2 | |
| 3 | The bindings are currently a work in progress and are far from complete. |
| 4 | Use at your own risk. |
| 5 | |
| 6 | Developer Info |
| 7 | ============== |
| 8 | |
| 9 | The single Python package is "llvm." Modules inside this package roughly |
| 10 | follow the names of the modules/headers defined by LLVM's C API. |
| 11 | |
| 12 | Testing |
| 13 | ------- |
| 14 | |
| 15 | All test code is location in llvm/tests. Tests are written as classes |
| 16 | which inherit from llvm.tests.base.TestBase, which is a convenience base |
| 17 | class that provides common functionality. |
| 18 | |
| 19 | Tests can be executed by installing nose: |
| 20 | |
| 21 | pip install nosetests |
| 22 | |
| 23 | Then by running nosetests: |
| 24 | |
| 25 | nosetests |
| 26 | |
| 27 | To see more output: |
| 28 | |
| 29 | nosetests -v |
| 30 | |
| 31 | To step into the Python debugger while running a test, add the following |
| 32 | to your test at the point you wish to enter the debugger: |
| 33 | |
| 34 | import pdb; pdb.set_trace() |
| 35 | |
| 36 | Then run nosetests: |
| 37 | |
| 38 | nosetests -s -v |
| 39 | |
| 40 | You should strive for high code coverage. To see current coverage: |
| 41 | |
| 42 | pip install coverage |
| 43 | nosetests --with-coverage --cover-html |
| 44 | |
| 45 | Then open cover/index.html in your browser of choice to see the code coverage. |
| 46 | |
| 47 | Style Convention |
| 48 | ---------------- |
| 49 | |
| 50 | All code should pass PyFlakes. First, install PyFlakes: |
| 51 | |
| 52 | pip install pyflakes |
| 53 | |
| 54 | Then at any time run it to see a report: |
| 55 | |
| 56 | pyflakes . |
| 57 | |
| 58 | Eventually we'll provide a Pylint config file. In the meantime, install |
| 59 | Pylint: |
| 60 | |
| 61 | pip install pylint |
| 62 | |
| 63 | And run: |
| 64 | |
| 65 | pylint llvm |
| 66 | |
| 67 | And try to keep the number of violations to a minimum. |
