Spyder Version: 2.3.0 Python Version: 2.7.6 Qt Version : 4.8.6, PyQt4 (API v2) 4.10.4 on Windows pyflakes >=0.5.0: 0.8.1 (OK) pep8 >=0.6 : 1.5.6 (OK) IPython >=0.13 : 2.1.0 (OK) pygments >=1.6 : 1.6 (OK) sphinx >=0.6.6 : 1.2.2 (OK) psutil >=0.3 : 1.2.1 (OK) rope >=0.9.2 : 0.9.4 (OK) matplotlib >=1.0: 1.3.1 (OK) sympy >=0.7.0 : 0.7.5 (OK) pylint >=0.25 : None (NOK)

I often use cython either to speed up some computations or to call C code directly. Currently spyder provides syntax highlighting only, but other thinks would be interesting and not too complicated:

• cdef and cpdef should be recognized as function definitions in the highlighter. cdef is ambiguous (see below) but cpdef is not.
• validate cython files by running cython and checking for error, like pyflakes does for cython files (only .pyx -> .c, not actually compiling the c file because it's quite slow)
• integration into the outline explorer. That can be tricky because the cdef keyword can be used for variables, classes, functions and methods.

Viewing the outline of a Cython file would be very handy.
