[mockery]

Yes! The 010 Editor's templating language is a nearly unique (in my experience) hybrid between C-like declarations and imperative flow that's exactly what I want for parsing arbitrary binary files.

The template executes like a script (with conditionals and looping) and a line like "int32 myNum;" is actually just syntactic sugar for "read 4 bytes from the current file pointer and label it myNum." Their example probably does a better job explaining it than I can:

  struct FILE {
      struct HEADER {
   char    type[4];
          int     version;
          ushort  numRecords;
      } header <bgcolor=cLtGray>;
  
      struct RECORD {
          int     employeeId;
          char    name[40];
          float salary;
          if( file.header.version > 1 )
              int      numChildren;
          if( file.header.version > 2 )
              time_t   birthDate;
      } record[ file.header.numRecords ];
  
  } file;
