Roadmap

Here is a list of features we would like to be implemented, grouped by milestone.

Milestone 1 (planned for end of 2016)

Incremental parsing

Do lexical analysis [?]

• Integrate ANTLR current version: 4.5 since then

Do syntactic analysis [?]

• Write a complete Cobol grammar
• Build ANTLR tokens into into code elements
• Implement 100% of Cobol syntactic errors

Do semantic analysis

• Build an abstract syntax tree [?]
• Build a symbol table [?] since then
• Be able to resolve naming errors since then
• Build a representation for Cobol types
• Be able to resolve type errors
• Implement 100% of COBOL semantic errors

Run as a server to be incremental

• Be able to run as a stateful server since then
• Optimize data serialization
• Define an interface for the server allowing to support all features of a modern IDE

Cobol 85

• Full Cobol 85 support (full grammar is written, but we still need to implement semantic checks)

Cobol 2002

• Type (weaked and strong)

TypeCobol language

• Intrinsic type based on Cobol 2002 type:
  • Types Date, bool, amount
• "::" operator which is used as the dot operator in modern language

Multiple layer of (Type)Cobol language

Integration to the incremental parser

• Write the language grammar (TypeCobol and Cobol 2002) as a superset of Cobol 85 grammar
• Extend the Cobol 85 AST with Cobol 2002 and TypeCobol CodeElements

Code generation

• Generate Cobol 85 code from a Cobol 2002 AST
• Generate Cobol 2002 code from a TypeCobol AST
• Make the generated code RCS friendly
• Make the generated code Cobol debugging friendly
