From 258be7065a38f8cd550864997af0c3ddd601df7d Mon Sep 17 00:00:00 2001 From: Claude Date: Fri, 23 Jan 2026 23:13:26 +0000 Subject: [PATCH 1/2] feat: add view:// protocol for read-only file viewing Implemented a new view:// protocol that acts as a liberal wrapper for file viewing with the following features: - Opens text files in VSCode with preview mode (read-only) - Opens binary files (PDFs, images, videos, etc.) with system default viewer - Shows error if file doesn't exist (doesn't create files like edit://) - Supports both standard markdown [text](view://path) and wiki-style [[view:path]] syntax - Handles paths flexibly with spaces, special characters, URL encoding - Works across all platforms (macOS, Windows, Linux) Binary file extensions supported: PDF, PNG, JPG, GIF, SVG, MP4, MP3, ZIP, and more. Updated documentation: - README.md with protocol comparison table and usage examples - CHANGELOG.md with new features - AGENTS.md with manual testing guidelines - Added TEST-RESULTS.md with implementation details and test plan - Added test-view-protocol.md with comprehensive test cases - Added test files for validation https://claude.ai/code/session_015oy2Dj4RFQhfTwVKBPRFch --- AGENTS.md | 1 + CHANGELOG.md | 9 ++++ README.md | 24 ++++++++- TEST-RESULTS.md | 101 ++++++++++++++++++++++++++++++++++++ src/extension.ts | 71 +++++++++++++++++++++++-- test-files/sample-image.png | Bin 0 -> 70 bytes test-files/sample-text.txt | 4 ++ test-view-protocol.md | 40 ++++++++++++++ 8 files changed, 243 insertions(+), 7 deletions(-) create mode 100644 TEST-RESULTS.md create mode 100644 test-files/sample-image.png create mode 100644 test-files/sample-text.txt create mode 100644 test-view-protocol.md diff --git a/AGENTS.md b/AGENTS.md index b6a454b..dffe1b5 100644 --- a/AGENTS.md +++ b/AGENTS.md @@ -30,6 +30,7 @@ -
