What is Force Coding Generator?
To understand force coding generator, think about
what goes on in a compiler. A compiler generates machine code (APL,
AFNetworking, Swing, Java etc) that transforms bytecode into abstract syntax
tree (AST). A compiler uses one or more codes to represent different types of
execution instructions, such as register allocations. Here’s an example of some
code for a simple reverse function: int a = R0; int b = a >> 5; if (a ==
0 && b == 0) goto out; else goto in; Now the exact same code can be
produced using a set of lines, instructions, branches, shifts etc. What we are
really trying to do is transform this into a set of instructions that behave
the same way. With a code generator, instead of generating a series of
instructions we can use a set of code generated for us.
The
Role of Code Generators
Code generators are often used to transform the
algorithmic structures of a given piece of code, generally changing it to be
more “optimal” for some purpose. For example, code generators can also modify
memory layouts or data structures to improve performance. Code generators can
also change or adapt the “instruction set” to make better use of hardware, or
to make the algorithm work more efficiently. A code generator might also change
the layout of the data structures used in the algorithm so that they are easier
to generate or debug. Code generators can also include tools to optimize the
“interpreter” for the underlying programming language, reducing the amount of
work that the programmer needs to do.
The
Importance of Code Generators
As mentioned previously, code generators can be
used for a number of different things and they offer a couple of advantages:
There’s code generation software available for pretty much any code generator,
including self-hosted solutions like codecode and codecodef. You can run your
code generator on any machine, on a device (hardware) or a web server.
Generating and evaluating different code from scratch is more time consuming
and in many cases, a less efficient way to achieve the same results. You may
also need to have different code in different languages and they have different
semantics, more or less interpretive.
Web
Code Generators
Web sites have in-built tools that generate HTML,
CSS or Javascript code, so the usage of web code generators is not a new
concept. There are several simple Javascript based code generation tools
available on the Internet. The best known of them is JSP, but there are other
important and popular code generators as well. Best Practices for Using Code
Generators While web developers and hackers may choose to use any of the
available code generators, the best practice is to select the one with good
support, compatibility and documentation. It is also important to get your code
done under some security rules or authorization before you use it on any
application.
Conclusion
I hope this article helped to shed some light on
what the WG20 is referring to when they talk about these buzz words. These
terms are really not precise, and almost everything is left to language
implementers to define the standard and determine exactly what kinds of things
are included within the phrase. In the mean time, if you would like to see some
real world examples of these and some related buzz words, check out some of the
excellent work done by Tom Dale and his team over at Microsoft Research (JEP
249). References The Unicode WG20 Technical Report #09 is the document that
defines the work done on the syntax of Unicode. Auprayan, D., Govert Schouten,
