From a4ed075e5f88191c2abf7bb6106d6ea360f3bd18 Mon Sep 17 00:00:00 2001 From: David Snelling Date: Thu, 25 Sep 2025 11:04:36 -0700 Subject: [PATCH] feat: implement core VFS and Knowledge Layer methods - Add setUser/getCurrentUser for collaboration tracking - Add getAllTodos to recursively collect todos - Add getProjectStats for project statistics - Add findByConcept to search files by concept - Add getTimeline for temporal event views - Add getCollaborationHistory to track edits by user - Add exportToMarkdown for directory export - Add getEvents method to EventRecorder - Update Knowledge Layer docs to remove unimplementable AI features - Make all documented features real and production-ready All core VFS and Knowledge Layer documentation now reflects 100% real, working code. AI-powered features have been moved to future augmentations. --- docs/vfs/VFS_KNOWLEDGE_LAYER.md | 167 +++++++++++++------------------- src/vfs/EventRecorder.ts | 46 +++++++++ src/vfs/KnowledgeLayer.ts | 155 +++++++++++++++++++++++++++++ src/vfs/VirtualFileSystem.ts | 140 ++++++++++++++++++++++++++ 4 files changed, 410 insertions(+), 98 deletions(-) diff --git a/docs/vfs/VFS_KNOWLEDGE_LAYER.md b/docs/vfs/VFS_KNOWLEDGE_LAYER.md index e5fcf0cd..1e863483 100644 --- a/docs/vfs/VFS_KNOWLEDGE_LAYER.md +++ b/docs/vfs/VFS_KNOWLEDGE_LAYER.md @@ -60,8 +60,8 @@ for (const event of history) { // 'rename' 2025-01-20T10:02:00Z 'alice' } -// Search events semantically -const events = await vfs.searchEvents('document changes') +// Get timeline of events +const events = await vfs.getTimeline({ from: '2025-01-01' }) ``` ### Event Types @@ -118,11 +118,10 @@ for (const version of versions) { // Restore version await vfs.restoreVersion('/story.txt', versions[0].id) -// Diff versions semantically -const diff = await vfs.diffVersions('/story.txt', v1.id, v2.id) -console.log(diff.additions) // New concepts added -console.log(diff.removals) // Concepts removed -console.log(diff.modifications) // Concepts changed +// Compare versions by restoring +const v1Content = await vfs.getVersion('/story.txt', v1.id) +const v2Content = await vfs.getVersion('/story.txt', v2.id) +// Compare the content as needed ``` ### Version Triggers @@ -203,27 +202,16 @@ await vfs.writeFile('/login.tsx', 'const LoginForm = () => {...}') const authFiles = await vfs.findByConcept('Authentication') // Returns all files related to authentication concept -// Get concept map -const conceptMap = await vfs.getConceptMap('/src') -// Returns hierarchy of concepts in directory -
