jgd 0.2.0

No user-facing changes.

Organizational

• The jgd repo has been migrated to the REditorSupport GitHub organization. The maintainers remain the same, but the package URL and bug-report links have been updated accordingly. The migration reflects our tight integration with the (just released) v3.0.0 version of the vscode-R extension. We emphasize that jgd remains frontend-agnostic and encourage integration with other IDEs and R frontends.

jgd 0.1.1

Internals

• Fixed potential GC protection issues in the C internals (flagged by rchk) by tightening PROTECT/UNPROTECT handling around allocations in replay_snapshot and C_jgd_discover. (#61)

Documentation

• Improved visibility of protocol specification. (#58)
• Minor documentation updates reflecting the fact that our VS Code functionality has been absorbed into the main/upstream VS Code R extension. (https://github.com/REditorSupport/vscode-R/pull/1706).

jgd 0.1.0

Initial CRAN release.

• C-based graphics device that serializes R plotting operations to JSON (JSONL) and streams them over a local connection to an external renderer.
• Transport support for Unix domain sockets (Linux/macOS), Windows named pipes, and TCP.
• Automatic server discovery via platform-specific cache directory.
• Remote font metrics: the device queries the renderer for string widths and glyph metrics, enabling accurate text layout without local font dependencies.
• Plot history with resize replay: snapshots are captured per page so historical plots can be re-rendered at new dimensions.
• Experimental extension API (jgd_ext(), jgd_frame_ext(), jgd_begin_group()) for injecting renderer-specific properties beyond R’s standard graphics parameters.
• Bundled cJSON (v1.7.19) for zero external dependencies.

These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
