• Cython - properly declaring C funs

  - by deepblue

  I'm having trouble with running a bare example. I'm using this to declare a function in Cython coming from cinterf.h header: cdef extern from 'cinterf.h': int xsb_init_string(char* p_xsb_path) The declaration in the C header file is: DllExport extern int call_conv xsb_init_string(char *); both DllExport and call_conv are macros defined elsewhere, and resolve to GCC compiler directives. do I have to use those as well inside cdef to fully match the declaration? When I call xsb_init_string() as: xsb_init_string('some string') The python interpreter gives me: 'ImportError: ./py_ext.so: undefined symbol: xsb_init_string' Am I declaring the xsb_init_string() signature properly, inside cdef?

• python,running command line servers - they're not listening properly

  - by deepblue

  hello all Im attempting to start a server app (in erlang, opens ports and listens for http requests) via the command line using pexpect (or even directly using subprocess.Popen()). the app starts fine, logs (via pexpect) to the screen fine, I can interact with it as well via command line... the issue is that the servers wont listen for incoming requests. The app listens when I start it up manually, by typing commands in the command line. using subprocess/pexpect stops the app from listening somehow... when I start it manually "netstat -tlp" displays the app as listening, when I start it via python (subprocess/pexpect) netstat does not register the app... I have a feeling it has something to do with the environemnt, the way python forks things, etc. Any ideas? thank you

• implementing type inference

  - by deepblue

  well I see some interesting discussions here about static vs. dynamic typing I generally prefer static typing, due to compile type checking, better documented code,etc. However I do agree that they do clutter up the code if done the way Java does it, for example. so Im about to start building a language of my own and type inference is one of the things that I want to implement, in a functional style language... I do understand that it is a big subject, and Im not trying to create something that has not been done before, just basic inferencing... any pointers on what to read up that will help me with this? preferably something more pragmatic/practical as oppose to more theoretical category theory/type theory texts. If there's a implementation discussion text out here, with data structures/algorithms, that would just be lovely much appreciated

• github repos cloning, but no tags/branches recreated??!!

  - by deepblue

  I've been cloning a few repos from github that, even though I know they have branches/tags, do not have them once I clone them onto my local drive. strage. I try to list the tags (git tag) but nothing comes up... I would look into .git/refs/tags/ and that too is empty. the repos in question are: http://github.com/jchris/hovercraft.git http://github.com/apache/couchdb.git any ideas? I really need specific tags/branches, and not the HEAD of the master

• How do I pass struts2 <s:select multiple="true"> with a Map

  - by deepblue

  I have an bean placed on my action Event.java, the action is Called ManageEvents. I would like the user to be able to add to a struts2 multiple select form field and create a list or map of items (in this case Map where the data would be . <struts2:select name="event.dj_map" label="Add DJs To Your Event" list="event.dj_map" listsize="5" multiple="true" headerKey="headerKey" required="true" headerValue="--- Please Select ---"> So ultimately I would like to know how to pass a mult. select field (e.g. Events.dj_map) as a map of name,value pairs to an object (e.g. Event.java) set on the action (e.g. ManageEvents.java).
