UPDATE 2017-04-26: Updated this page to link to my new and improved version of the ANSI CL standard draft which now includes a pdf sidebar outline.

Below is a link to a build of the publicly available ANSI CL standard draft, which has been somewhat modified to include a pdf sidebar outline. The sidebar makes it much easier to navigate this 1200 page plus document!

If you are curious to see what modifications I had to make to the tex sources to obtain the above pdf, please refer to the gitlab repository hosted here.

There are two common ways of going about defining a graphical user interface.

1. Declarative UI.
   1. You adapt a markup language like HTML or XML, possibly in combination with a layout language like CSS, to define the identity and basic placement of widgets and controls.
   2. You traverse your declared UI using a real programming language like Javascript in order to add functionality and advanced UI features.
   3. This approach has been adopted by frameworks such as AngularJS, and QT+QML, and is the standard approach for Android UI development.
2. Programmatic UI.
   1. You create and lay-out the elements of the UI directly in a programming language. While you may still achieve separation of concerns by delegating UI creation and layout to a dedicated "View" object, all actions necessary to construct the UI are programmatically guided instead of declaratively specified.
   2. All older UIs used this approach, and it is commonly used today to construct UIs for a vast variety of desktop frameworks and can also be used to manipulate the web DOM.
   3. Swing, SWT, GTK, QT, is an option for Android.

Is one approach better than the other? What are the upsides and downsides of each approach?

1. There are multiple ways to think about problems. *
2. Given a real-world or programming problem, often if you find the right abstraction to model it you can make the problem vastly simpler and/or make your software vastly higher quality.
3. Therefore, solving a problem well should involve trying to find the best abstraction possible.
4. Programming languages influence your thought processes to match what they offer.
   1. "if you see enough nails everything starts to look like a hammer".
   2. See: Sapir Whorf hypothesis and Paul Graham: Succinctness is Power.
5. Lisp offers the flexibility to adapt to ANY paradigm, imposes the least constraints on your thinking, and therefore is likely often the best language to use to approach a problem. **

\* I hold the idea that there are multiple ways to think about problems to be fairly obviously true. But in case you don't agree yet, here is some justification. An example of a problem which can be profitably approached from multiple perspectives is "dynamic programming". I can either approach a dynamic programming problem using a top-down recursive viewpoint, or look at it from the bottom up as filling out values in a table. I can reason about DP as either constructing a DAG of subproblems or as filling out a table of precomputed values. There are MULTIPLE WAYS to think about the problem

I know these directions are a bit sketchy, for now I am just writing down what I remember from the process. I will test these instructions on a fresh box soon.

1. Install SDL. Download SDL for mingw, ignore the install directions. Instead copy things into your c:/mingw directory.
2. Install glew. download sources and compile with msys. then copy into appropriate directories (dlls go in C:\Windows\SysWOW64").

3. Build the attached "test\_opengl.c" with the following command:

   gcc -o test.exe test_opengl.c -lopengl32 -lmingw32 -lSDL2main -lSDL2 -lglew32
   

4. profit.
