Pattern Based Text Generator Specifications

The Pattern-Based Text Generator PTG supports translations into any kind of structured text.

Typical patterns: 

    Pair: "(" $ "." $ ")"       /* ordinary pattern */
    Decl: $2 ":" $1 ";"         /* indexed pattern */
    Ident: $ string $ int       /* typed pattern */
    CommaSeq: $1 {", "} $2      /* optional pattern */
    IndText: [Indent $2 int] $1 /* function call pattern */
Typical Error Situations

  • Wrong number of parameters in PTG function application:

    ==> ERROR: prototype mismatch: 3 args passed, 2 expected

  • Wrong type of parameters in PTG function application:

    ==> argument #3 is incompatible with prototype

  • Correct PTG function signature but wrong parameter order:
