code-office

Showcase

Built for the review work that AI-era document flows actually create.

The extension is not an AI generator. It is the VS Code surface for the document formats that show up around AI-assisted work: generated DOCX drafts, Korean HWP/HWPX references, Markdown notes, PDFs, spreadsheets, archives, and source files that need to stay inspectable together.

Format wall

HWP, DOCX, XLSX, PDF, PPTX, and HTML stay in the same review room.

AI-era document work is rarely a single file. code-office keeps the generated brief, the Korean source form, the spreadsheet gate, the PDF evidence packet, the presentation narrative, and the HTML export visible as one workspace story.

Bundled local runtime

HWP/HWPX opens in Viewer first, then switches into editing without leaving the tab.

The default path loads a packaged rhwp-studio build from the extension, not a remote page. The same inherited cweijan.hwpEditor tab now owns internal Viewer and Editor modes, remembers the last mode selected by the user, and keeps dirty state, save, backup, revert, and format checks under VS Code's editable CustomEditor lifecycle.

Viewer first

HWP/HWPX files open in a stable Viewer surface by default. Edit/View switches stay inside the same custom editor tab.

Save PDF

The Viewer toolbar and Command Palette use a native rhwp PDF helper when the current-platform binary is packaged, then fall back to image PDF export.

Internal find

Cmd+F / Ctrl+F opens HWP search inside the WebView, highlights rendered SVG text in Viewer, and routes Editor search through rhwp's own find control.

File coverage

One extension for the files that usually scatter a workspace.

Family	Extensions	Mode	Implementation note
HWP / HWPX	.hwp, .hwpx	Viewer + editable	Bundled local rhwp-studio WASM runtime, native-first Save PDF, SVG/debug export, and WebView-local find highlighting.
Markdown	.md, .markdown	Editable	Vditor Live Preview, Reading Preview, Raw Source, boundary-aware wikilinks, and inherited export paths.
Word	.docx, .dotx	Editable	Dedicated DOCX custom editor using SuperDoc (@superdoc-dev/react) and the VS Code save lifecycle.
Excel	.xls, .xlsx, .xlsm, .csv, .ods	Preview / inherited edit paths	Spreadsheet viewer stack from the office lineage.
PowerPoint	.pptx, .pptm, .ppsx	Read-only viewer	PowerPoint-like viewer with visual thumbnails, resizable/collapsible sidebar, speaker notes, grid, fullscreen, presenter view, and zoom.
Legacy PowerPoint	.ppt	Optional fallback	LibreOffice conversion is opt-in and disabled by default.
PDF, images, fonts, archives	Multiple	Preview	Viewer surfaces inherited and kept behind release smoke checks.

Install

Install from a public registry, or build the verified local VSIX fallback.

Local VSIX fallback

npm install
npm run release:local
code-insiders --install-extension ./code-office-<version>.vsix --force

HWP/HWPX files are still registered through the inherited cweijan.hwpEditor custom editor ID for compatibility. Public branding and repository metadata point to this independent project. Older vscode-obsdian.hwp.* settings are read as a fallback; new HWP settings use code-office.hwp.*. Tag-based GitHub Releases attach Marketplace/Open VSX VSIX artifacts with SHA256SUMS.txt checksums; registries and the local VSIX gate remain verified install paths.

Release artifacts: GitHub Releases. HWP support contract: HWP/HWPX compatibility matrix. Product positioning: competitive context.

Release discipline

Packaging is treated as a smoke test, not a final afterthought.

Registry targets

Release source is main. VS Marketplace publishes jun6161.code-office; Open VSX publishes lidge-jun.code-office from a dedicated publisher-adjusted VSIX. The dev/wikilink-authoring-autocomplete branch is not a release source.

Local gate

npm run release:local

Type-checks, builds, verifies HWP hardening, builds the current-platform native PDF helper, packages the VSIX, and inspects packaged contents.

GitHub Release

.github/workflows/release.yml builds Marketplace and Open VSX VSIX files, writes SHA256SUMS.txt, creates provenance attestations, uploads workflow artifacts, and publishes tagged releases.

VSIX inspection

Checks that rhwp WASM, rhwp-vscode media, the current-platform native PDF helper, NOTICE, and LICENSE are included while vendor sources, samples, docs, native Rust source, and scripts are excluded.

Manual smoke

Install the VSIX, open and save HWP/HWPX, then spot-check Markdown, HTML, XLSX, DOCX, PDF, PPTX, image, and archive surfaces.

Roadmap

Next work is deliberately scoped instead of hidden behind fork branding.

Expanded Obsidian-style Markdown authoring polish after the Live Preview, Reading Preview, Raw Source, and wikilink baseline.
PPTX visual-fidelity and large-deck performance stabilization beyond the current PowerPoint-like view-only UX.
Markdown CJK inline formatting and strikethrough regression coverage.
Excel strikethrough and style preservation.
Optional LibreOffice fallback completion for legacy presentations.

Support and safety

Document viewers touch private files, so support starts with redacted repros.

code-office is designed for local document review. Keep private office files out of public issues, use synthetic or redacted samples, and treat remote HWP studio URLs as trusted-code inputs.

Issues

Report reproducible bugs and feature requests with file type, VS Code version, and redacted sample details.
