CSC 355 Language Processing
Fall 2005
Language Specification Project - working document
Last update:11/29/05 new submission guidelines

Significant update: Official language design document - Language Definition  .

Deadlines

• Nov 1- Scanner/Parser specification
• Nov 3 - Validate sample programs
• Nov 19 - Front-end should be nearing completion
• Code generation

Project submission:

• Thursday Dec 8; In-class demo & report submission
• Show progress on project; sample files; some key elements of spec
• Show the build process for your system
• Approximately 10 minutes
• Written report (Word) summarizing accomplishments; supply key portions of spec files
• Reminder: Take home exam on 12/8 due 12/13; in-class final on 12/13 at 8:00 am

Tuesday 11/1: Turn in: Prototype for Programs, Scanner & Parser

• Completed lex file
• Program that reads source text and tokenizes it
• BNF rules for the language constructs
• Read source program and print some rules to trace progress
• Sample programs
  • Each group should develop 1 interesting sample program
  • Interesting --> uses features of the language and/or does something useful/creative

Thursday 11/3: Validate sample programs

• Determine if the proposed sample programs are valid.
• If a program is approved, it will become a part of our test suite.
• If a program has issues, we must address them now to be sure our understanding of the language specification is correct.

Nov 19 - Front-end should be nearly complete

• Scanner
• Parser
• Static Semantics
  • variables are declared
  • type usage is consistent
• continue to improve error messages
• Should be able to handle some small programs
  • begin with a subset of the language features, and then add
• Better to have one complete end-to-end example than only one phase complete

Sample Programs - supplied by teams

• Sample programs (7 test programs).
