recursive descent การใช้

ประโยคมือถือ
  • LL grammars can also be parsed by recursive descent parsers.
  • This idea can be used to generate a recursive descent parser for formulas.
  • The packrat parsing is the recursive descent parsing algorithm that is accelerated using memoization.
  • Even when they terminate, parsers that use recursive descent with backtracking may require exponential time.
  • A " predictive parser " is a recursive descent parser that does not require backtracking.
  • It is rather easy for students to write a recursive descent parser for such a simple syntax.
  • A variant of the AA compiler included run-time support for a top-down recursive descent parser.
  • The Tcl library is a hybrid BNF-style definition of a recursive descent parser via sub-rules.
  • In computer science, a "'recursive descent parser "'is a kind of grammar.
  • Recursive descent with backtracking is a technique that determines which production to use by trying each production in turn.
  • Recursive ascent has also been merged with recursive descent, yielding a technique known as recursive ascent / descent.
  • Thus, the parser is " directly encoded " in the host language similar to recursive descent.
  • So recursive ascent parsers are generally slower, less obvious, and harder to hand-modify than recursive descent parsers.
  • This article is about the formal properties of LL grammars; for parsing, see LL parser or recursive descent parser.
  • The parser uses recursive descent; Fuzzy parsing is supported by so-called ANY symbols that match complementary sets of tokens.
  • Perl 6 sandwiches an operator-precedence parser between two Recursive descent parsers in order to achieve a balance of speed and dynamism.
  • Operator precedence parsers are also embedded within compiler compiler-generated parsers to noticeably speed up the recursive descent approach to expression parsing.
  • It assumes that the " primary " nonterminal is parsed in a separate subroutine, like in a recursive descent parser.
  • Recursive descent was popularised by Niklaus Wirth with PL / 0, an educational programming language used to teach compiler construction in the 1970s.
  • By contrast, Hamilton uses a top-down recursive descent parser that allows it to compile commands and procedures to an internal form before running them.
