当完成编写BNF后,就可以右键选择Generate Parser Code菜单,这样就会生成前面提到的Aop开头的类和接口等,其中Parser结尾的就是解析器类: 生成相关的PsiElement子接口和实现类等 再右键,选择Generate JFlex Lexer菜单,就可以得到_PointcutExpressionLexer.flex文件: 生成_PointcutExpressionLexer.flex文件 打开_PointcutExpressio...
第二步,transform,理解了源码之后,就是进行各种转换了,转译器全称转换编译器,主要工作就在于转换上,对 ast 进行不同目的的增删改。 第三步,generate,转换完的 ast 进行递归打印,生成新的代码,并且生成记录之前的源码和之后的源码的关联关系的 sourcemap。 虽然都是分为这三个阶段,...

上文所述的parser其实都是parser generator,generate出来的代码都是不可compose的,你写一个SQL parser,不能说先写一个select的parser,然后再写一个create table的parser,把两个compose起来,就是支持select和create的parser。你无法这么做。但parsec可以。在parsec里,你可以从一个很细力度的parser写起,一路将其compose...
Generating a data parser for parsing an input stream of data objects includes receiving information representative of a hierarchical data format defining a plurality of objects organized in a hierarchy. The objects include one or more schema objects representing data objects, and one or more container...
, the placeholder can generate three distinct items, each with its own interpretation. In each case, the presence of the item in some set in the canonical collection indicates input that the parser has seen is consistent with the occurrence of an A followed by an ...
JsonParser parser2 = factory.createParser(...); JsonParserparses JSON using the pull parsing programming model. In this model the client code controls the thread and calls the methodnext()to advance the parser to the next state after processing each element. The parser can generate the follow...
A Parser Generator uses this grammar file to generate a parser. The parser can be updated merely by updating the grammar and regenerating. The generated parser can use efficient techniques that would be hard to build and maintain by hand....
