Wed, 22 Jun 2011 16:55:48 UTC

Sometimes (ex. django templates section at setting.py), a function expects an absolute path, but it's more practical when developing to refer it to the current file position in our code base. The rel function does exactly that.

(C++) Macro to ease auto_ptr usage - jarnaldich

Fri, 12 Dec 2008 03:17:25 UTC

Use this macro to help declaring auto-release pointers in C++. See usage in the source. Remember that std::auto_ptr is a standard template class that helps releasing memory, since the pointer you provide in the constructor will be released in the destructor of the class. This means that memory is released "automagically" when the variable goes out of scope. Use of this class is specially advisable in a method with serveral returns or capable of throwing an exception.

(Scheme) Grouping keys of an associative list - jarnaldich

Wed, 30 Apr 2008 14:23:31 UTC

Given an an associative list ((k1 . v1) (k2 . v2) ... (kn . vn)), with possibly equal values for ki, it returns another alist where all cells have distinct keys and where values originally associated to the same key have been grouped as a list in the new cons cell. Ouch! This is much harder to explain than to code. Just check the commented example in the code.
