--------------------------------
Fix Version/s: 0.24.0
Resolution: Fixed
> Add Mermaid diagram generator (--gen mmd)
> -----------------------------------------
>
> Key: THRIFT-6026
> URL: https://issues.apache.org/jira/browse/THRIFT-6026
> Project: Thrift
> Issue Type: New Feature
> Components: Mermaid - Compiler
> Reporter: Jens Geyer
> Assignee: Jens Geyer
> Priority: Minor
> Fix For: 0.24.0
>
> Time Spent: 0.5h
> Remaining Estimate: 0h
>
> The Thrift compiler already ships a Graphviz generator (--gen gv) for
> visualising IDL type graphs. This ticket adds an analogous Mermaid
> classDiagram generator (--gen mmd) that produces .mmd files renderable
> natively on GitHub, GitLab, Confluence, Obsidian, and other platforms without
> requiring external tooling.
> Features:
> - All IDL constructs mapped to Mermaid classDiagram: enum (<<enumeration>>),
> struct (<<struct>>), union (<<union>>), exception (<<exception>>), typedef
> (<<typedef>>), service (<<service>>)
> - Service extends rendered as inheritance arrows (--|>)
> - Container generics using tilde syntax (list~T~, map~K,V~) for Mermaid
> compatibility
> - Optional :exceptions flag to draw dashed dependency arrows from service
> functions to declared exception types
> - When invoked with -r, the root program diagram aggregates types from all
> transitively included programs into a single output file
> - Constants intentionally omitted (visual noise, no structural value in a
> type diagram)
> - Output in gen-mmd/<programname>.mmd
> Implementation: single new file
> compiler/cpp/src/thrift/generate/t_mmd_generator.cc plus one
> THRIFT_ADD_COMPILER entry in compiler/cpp/CMakeLists.txt. No library changes.
