Here are just a few of the things you can do: Configure your build for x86 or ARM native platforms.
Generating parsers automatically There are tools that can generate a parser.
You feed them the grammar of your language—its vocabulary and syntax rules—and they generate a working parser. Creating a parser requires a deep understanding of parsing and it's not easy to create an optimized parser by hand, so parser generators can be very useful.
WebKit uses two well known parser generators: Flex for creating a lexer and Bison for creating a parser you might run into them with the names Lex and Yacc.
Flex input is a file containing regular expression definitions of the tokens. Bison's input is the language syntax rules in BNF format. Not a context free grammar As we have seen in the parsing introduction, grammar syntax can be defined formally using formats like BNF.
HTML cannot easily be defined by a context free grammar that parsers need. There are lots of available XML parsers. The difference is that the HTML approach is more "forgiving": On the whole it's a "soft" syntax, as opposed to XML's stiff and demanding syntax.
This seemingly small detail makes a world of a difference. On one hand this is the main reason why HTML is so popular: On the other hand, it makes it difficult to write a formal grammar. So to summarize, HTML cannot be parsed easily by conventional parsers, since its grammar is not context free.
This format is used to define languages of the SGML family. The format contains definitions for all allowed elements, their attributes and hierarchy. There are a few variations of the DTD. The strict mode conforms solely to the specifications but other modes contain support for markup used by browsers in the past.
The purpose is backwards compatibility with older content. The current strict DTD is here: The root of the tree is the " Document " object.
The DOM has an almost one-to-one relation to the markup. It is a generic specification for manipulating documents. A specific module describes HTML specific elements.
The HTML definitions can be found here: Browsers use concrete implementations that have other attributes used by the browser internally.The Design of Writing and the Writing of Design - No one will ever escape the necessity of writing. Even entering a career dealing with math and art – like architecture – does not mean that a person will not need writing skills.
At the Writing Center, we’re often asked “What makes good writing?” or “What makes someone a good writer?” Instructors wonder whether anyone can really be taught to write and why their students don’t know how to write by now.
Page Designer is a modern, intuitive, and exceedingly powerful browser-based Integrated Development Environment (IDE).
As a completely new IDE that is designed to greatly improve developer productivity, Page Designer enables you to very quickly develop and maintain your Application Express applications.
