Parse-Eyapp-1.155
River stage one • 1 direct dependent • 4 total dependents

Changes for version 1.155

  • A default lexer is built that can be used when no lexer is provided
  • eyapp -v option implies -N option
  • YYSymbolStack(0,-k) string with symbols from 0 to last-k YYSymbolStack(-k-2,-k) string with symbols from last-k-2 to last-k YYSymbolStack(-k-2,-k, filter) string with symbols from last-k-2 to last-k where filter can be code, regexp or string YYSymbolStack('SYMBOL',-k, filter) string with symbols from the last occurrence of SYMBOL to last-k where filter can be code, regexp or string
  • - Now YYSymbol(-k) provides the symbol associated with the k-th state from the top of the parsing stack
    • The debug format (yydebug activated) shows the transition symbols in the stack
    • The parsing stack stores the transition symbols
    • See file code/reducereduceconflictPPCR.eyp for a way to use it when solving conflicts
  • There was a bug in the tree directive when there was a token with name 'something' and a syntax variable with the same name something. Seems fixed. See t/75tokenandvariablewiththesamename.t
  • Added option -N (nocompact) to eyapp. The compacted output info about conflicts in the .output file isn't detailed enough. It does not describes in full detail which tokens and productions are involved
  • Labels only after %name accepted
  • -B prompt eyapp option added
  • -yml option in Parse::Eyapp::Driver::main to dump YAML
  • -C option == -B '' and -b ''
  • While %lexer provides $self, %conflict did not. Now consistent. $self is $_[0] (but the arg isn't shifted)
  • option -T for eyapp
  • #line in dynamic conflict handlers
  • Ambiguous calc example: exp: exp '-' exp with precedences dynamically changed by the user (LEFT, RIGHT). See file: examples/debuggintut/dynamicgrammar.eyp
