is there any way to use this regex module with pypy?
https://pypi.python.org/pypi/regex
or any alternative regex module that works with pypy and has the features of this regex module. I did copy regex module files from my python installation into pypys lib_pypy folder, but i cannot import this module, the error is:
ImportError: No module named _regex
it seems that it cannot import _regex.pyd file. I'm using pypy3-2.1-beta1-win32, windows xp.
I also tried building the library with pypy:
pypy setup.py build -c mingw32
and i've got this error:
error: package directory 'Python3' does not exist
I tried removing package_dir={'': PKG_BASE} from setup.py and retry the build, and then there was another error:
File "...\pypy3-2.1-beta1-win32\lib-python\3\distutils\cygwinccompiler.py", line 352, in check_config_h
fn = sysconfig.get_config_h_filename()
AttributeError: 'module' object has no attribute 'get_config_h_filename'

RegEx can be used to check if a string contains the specified search pattern. Python has a built-in package called re, which can be used to work with Regular Expressions. When you have imported the re module, you can start using regular expressions: The re module offers a set of functions that allows us to search a string for a match:
I'm trying to install the new Regex module The readme.txt says::: To build and install regex for your default Python run python setup.py install To install regex for a specific version run setup.py with that interpreter, e.g. python3.1 setup.py install
PyPy This module is targeted at CPython. It expects that all codepoints are the same width, so it won’t behave properly with PyPy outside U+0000..U+007F because PyPy stores strings as UTF-8. Old vs new behaviour
Alternative regular expression module, to replace re. This regex implementation is backwards-compatible with the standard ‘re’ module, but offers additional functionality. The re module’s behaviour with zero-width matches changed in Python 3.7, and this module will follow that behaviour when compiled for Python 3.7.
I'm afraid the library would have to be adapted to work with PyPy—PyPy doesn't support the same C extension mechanism CPython does. Also, I'm not sure if Python 3 support is ready or even usable in PyPy as of yet: they're still collecting donations for the py3k PyPy sub-project as per the right side of the home page of their site: http://pypy.org.
As to the C extension problem, if you have the time and willingness, you can try to port the library to use the CFFI module of PyPy (import cffi) to call into the C parts of regex. Luckily, as per http://doc.pypy.org/en/latest/release-2.0.0-beta2.html, CFFI is now built in to PyPy.
