Roadmap

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

Version 1.0 - Types and procedures (June 2017)

User features

TypeCobol language

• Type (weaked and strong) - specs comes from Cobol 2002 + Type Strict close to Strong
• Intrinsic type based on Cobol 2002 type: Date, bool
• :: operator which is used as the dot operator in modern language
• Procedures
  • Shorter syntax to declare a procedure than a sub-program
  • Control caller arguments during compilation time (partially)
    • Control only number of arguments and their type
  • Write clearly which arguments serves as input, output or both
  • Propose visibility mechanism: only public and private for now

Code generation

• Generate Cobol 85 code from a TypeCobol source file

IDE integration

• Preprocessor integration for RDz
• POC for integration with RTC (https://github.com/TypeCobolTeam/TypeCobolBuild)

Propose a Console Interface

• Parse a Cobol file to check for errors
• Convert a TypeCobol source file to a Cobol 85 file

Technical Considerations

• Cobol 85 parser with lexical, syntactic and semantic analysis
• Grammer of Cobol 85 is almost complete
• Semantic error are very limited : basically we check if variable are defined
• Cobol 2002 grammar only for Typedef
• Incremental parsing is done till syntactic phase

Version 1.1 - Implement Language Server (March 2018)

Implement LanguageServer protocol for :

• parsing in real time
• completion
• error in real time
• go to definition

Version 1.2 - Optimization (June 2018)

• Migration from Antlr to CUPS. Semantic phase is now 10x faster.

Version 1.3 - Namespace support (end of 2018)
