code-reuse

I have some standard SQLAlchemy models that I reuse across projects. Something like this: from sqlalchemy import Column, Integer, String, Unicode from sqlalchemy.ext.declarative import declarative_base Base = declarative_base() class Category(Base): __tablename__ = 'category' id = Column(Integer, primary_key=True) slug = Column(String(250), nullable=False, unique=True) title = Column(Unicode(250), nullable=False) def __call__(self): return self.title I'd like to put this in a shared library and import it into each new project instead of cutting and pasting it, but I can't, because the

In my WPF4 Desktop-based application there is a big block with sidebar menu that repeats in each window and takes about 70 lines of XAML. In order to improve code reuse, I would like to split XAML file in two files: XAML-file that contains code for sidebar menu (≈70 lines) Base XAML file that contains «include/reference» to XAML-file with sidebar menu code As I understood, there are two ways to implement my problem: Use ResourceDictionary Use UserControl / CustomControl My questions are: What is the difference between ResourceDictionary and UserControl ? Could you give me examples where I have

For a while now I have been killing spare time by creating a 2D game programming toolkit/library. It is written in Objective C, and consists of an OpenGL rendering system and a whole bunch of AI, physics code, a bunch of specialized containers and other game related stuff. Apart from the OpenGL based View mechanism (obviously), most of this code should be easily portable to iOS since it only uses the Foundation Framework and that framework appears to be implemented on iOS. So far I have only been testing the various components using a Cocoa NSOpenGLView but now I want to create a OS X/iOS

I've started to wrap my functions inside of Objects, e.g.: var Search = { carSearch: function(color) { }, peopleSearch: function(name) { }, ... } This helps a lot with readability , but I continue to have issues with reusabilty . To be more specific, the difficulty is in two areas: Receiving parameters . A lot of times I will have a search screen with multiple input fields and a button that calls the javascript search function. I have to either put a bunch of code in the onclick of the button to retrieve and then martial the values from the input fields into the function call, or I have to

I'm developing an app which I want to make available both for Android and Blackberry (possibly to JavaME in the future). The business logic will be common to all the platforms - and hence, so will the corresponding layer in code. But I also have a data layer - which will obviously be different to the various platforms. My approach to this is to have a bean and an abstract DataStore class. If I were using Android's NotePad sample, it would look like this: Note Bean: public class Note { private long id; private String title; private String note; private long created; private long modified; /

I have a .cs file full of C# code I keep reusing in multiple projects. Right now I'm including it in these projects by copying and pasting the code into a new file in each project directory. This is the wrong way to do it. What's the right way to do it? The right way should: keep the common code in only one place on my computer and keep the link fresh --- so when the common code changes, each project is aware of it, the next time I recompile that project. Randomly guessing, I'd expect some sort of directive like using mycode = C:\common\mycode.cs , but I'm sure that's not the .NET way of doing
