php - How to add new listener in the best way? -

-

i have project on zf 1.x , want use eventdispatcher symfony component. have 2 services user , topic. after success user authentication need activate user's topics. create event - authenticationevent , fire event after authentication in user service this

$dispatcher->dispatch('user.authentication.success', new authenticationevent($user));

but need add listener? code looks like

$listener = new topiclistener(); $dispatcher->addlistener('user.authentication.success', array($listener, 'onauthenticationaction'));

i had method authenticate in user service , there code lines calling method activate($user) activate topics in success case of authentication. whereupon had coupling between user , topic service. why decided use eventdispatcher.

so best place adding listeners? in bootstrap part of code?

i don't know zf. must add listener before dispatch event.

has "bootsrap" file? add listener there (or in front controller).

i'm trying give django-easy-pdf go, i'm having problems installing dependencies. i importerror: no module named xhtml2pdf.default when running django. to attempt fixing, did pip install xhtml2pdf , yields could not find downloads satisfy requirement pypdf (from xhtml2pdf) . so let's pip install --allow-unverified pypdf pypdf around that. completed without issues. when repeating pip install xhtml2pdf , software gets installed without issue. however, when launching django 1.6, get: importerror: reportlab version 2.1+ needed! . i have reportlab 2.2 or higher installed though, since pip freeze lists 3.0. it looks hardcoded in few files ( util.py , __init__.py ): if not (reportlab.version[0] == "2" , reportlab.version[2] >= "1"): raise importerror("reportlab version 2.1+ needed!") if not reportlab22: raise importerror, "reportlab toolkit version 2.2 or higher needed" how can fixed (except remove these c...

collision detection - C++ library for mesh to mesh intersection: what is available? -

-
i need calculate volume intersection , penetration depth between 3d triangular meshes (e.g. in .obj format), quite new computational geometry. in previous post ( mesh mesh intersections ) , google search, found few c++ libraries might appropriate job: cgal pqp libigl swift though, not sure 1 appropriate beginner. suggestion? libigl of version 1.1 has robust mesh boolean operations in igl/boolean/mesh_boolean.h . uses either implementation using cgal's exact arithmetic kernel or wrapper of cork (another option you). for now, libigl contains patched version of cork in libigl/external/cork , improves robustness. while implementing libigl's boolean ops, found cork faster not produce correct result (specifically, fails resolve intersections). libigl, using cgal backend, robust , still fast compared converting mesh cgal's nef_polyhedron , conducting csg operations , converting mesh. final conversion possible if result manifold. instead, libigl use...
