For interactive browsing, use `x hn` after loading `. ~/.x-cmd.root/X`. --- ## AI and Machine Learning Discussions Filter top stories for AI/ML topics using x jq: ```bash # Filter top stories for AI-related titles x hn top --json 1,100 | x jq '[.[] | select(.title | test("AI|artificial intelligence|machine learning|LLM|ChatGPT"; "i"))]' # Filter for LLM and model discussions x hn top --json 1,100 | x jq '[.[] | select(.title | test("GPT|Claude|Llama|neural|model"; "i"))]' # Filter for AI safety and alignment discussions x hn top --json 1,100 | x jq '[.[] | select(.title | test("AI safety|alignment|AGI"; "i"))]' ``` --- ## Programming and Development Filter top stories for programming topics: ```bash # Filter for programming language discussions x hn top --json 1,100 | x jq '[.[] | select(.title | test("Rust|Go|Python|TypeScript|JavaScript"; "i"))]' # Filter for web development x hn top --json 1,100 | x jq '[.[] | select(.title | test("React|Vue|frontend|backend|web"; "i"))]' # Filter for DevOps and infrastructure x hn top --json 1,100 | x jq '[.[] | select(.title | test("Kubernetes|Docker|DevOps|cloud"; "i"))]' # Filter for software engineering topics x hn top --json 1,100 | x jq '[.[] | select(.title | test("programming|coding|developer|software|GitHub|open source"; "i"))]' ``` --- ## Software Engineering News Get software engineering and tech industry discussions: ```bash # Filter for startup and business discussions x hn top --json 1,100 | x jq '[.[] | select(.title | test("startup|Y Combinator|funding|business"; "i"))]' # Filter for career and hiring topics x hn top --json 1,100 | x jq '[.[] | select(.title | test("hiring|interview|career|salary|remote"; "i"))]' # Show Ask HN posts (often career/business discussions) x hn ask --json 1,20 # Show Show HN posts (new projects/tools) x hn show --json 1,20 ``` --- ## Story Lists Get various story lists: ```bash # Get top stories (items 1-10) x hn top --json 1,10 # Get items 11-20 x hn top --json 11,20 # Other types x hn new --json 1,10 x hn best --json 1,10 x hn ask --json 1,10 x hn show --json 1,10 x hn job --json 1,10 ``` **JSON Fields:** ```json { "by": "username", // Author "descendants": 161, // Comment count "id": 47392084, // Post ID "kids": [47393177, ...], // Comment ID list "score": 582, // Points/upvotes "time": 1773609736, // Unix timestamp (seconds) "title": "Post Title", // Title "type": "story", // Type (story/job/etc) "url": "https://..." // URL } ``` **x jq Processing Examples:** ```bash # Extract title and URL x hn top --json 1,10 | x jq -r '.[] | "\(.title)\t\(.url)"' # Calculate average score x hn top --json 1,30 | x jq '[.[].score] | add / length' # Sort by score x hn top --json 1,50 | x jq -r '.[] | "\(.score)\t\(.title)"' | sort -rn | head -10 # Top domains statistics x hn top --json 1,100 | x jq -r '.[].url // empty' | \ sed -E 's|https?://||; s|/.*||' | sort | uniq -c | sort -rn | head -10 # Formatted briefing output x hn top --json 1,5 | x jq -r '.[] | "\n[\(.score) points] \(.title)\nAuthor: @\(.by) | Comments: \(.descendants)\n\(.url)\n"' # Filter for AI-related stories only x hn top --json 1,100 | x jq '[.[] | select(.title | test("AI|artificial intelligence|machine learning|LLM|ChatGPT"; "i"))]' # Filter for programming stories x hn top --json 1,100 | x jq '[.[] | select(.title | test("programming|coding|developer|software|GitHub"; "i"))]' ``` --- ## Post Details Get specific post details and comments: ```bash x hn item --json <id> ``` **Examples:** ```bash # Get post details x hn item --json 47392084 | x jq '.[0] | {id, title, by, score, descendants, url}' # Get comment ID list (first 20) COMMENT_IDS=$(x hn item --json 47392084 | x jq '.[0].kids[:20] | .[]') # Fetch each comment content (note: each item request takes time) for cid in $COMMENT_IDS; do x hn item --json "$cid" | x jq -r '[.by, .text[0:100]] | @tsv' done ``` **Note:** Posts with many comments have large data size, consider limiting output or batch processing. --- ## User Info Get user information: ```bash x hn user --json <username> ``` **Examples:** ```bash # Get key user fields (limit output for active users) x hn user --json dang | x jq '{id, created, karma, submitted: (.submitted | length)}' # Extract user profile x hn user --json dang | x jq '{ username: .id, created: .created, karma: .karma, about: (.about[0:200] // "") }' ``` **Note:** Active users have large data including all submission records, which may cause timeouts. Use x jq to limit output fields. --- ## User hn-index Calculate user influence metric: ```bash x hn hidx <username> ``` **Output Example:** ``` hn-index: 42 ``` **Note:** This command fetches all user submissions and may take time for active users. --- ## Caching x hn module has built-in caching: ```bash # View cache config x hn cfg cat # Default cache times # - Story data: 60 minutes # - Index data: 30 minutes # - Cache dir: ~/.x-cmd.root/local/cache/hn/ ``` --- ## Command Reference | Command | Description | Output | |---------|-------------|--------| | `x hn top --json N,M` | Top stories | JSON array | | `x hn new --json N,M` | New stories | JSON array | | `x hn best --json N,M` | Best stories | JSON array | | `x hn ask --json N,M` | Ask HN posts | JSON array | | `x hn show --json N,M` | Show HN posts | JSON array | | `x hn job --json N,M` | Job postings | JSON array | | `x hn item --json <id>` | Post details | JSON object | | `x hn user --json <name>` | User info | JSON object | | `x hn hidx <name>` | hn-index | Plain text | --- ## Dependencies - x-cmd (required): provides hn module - x jq (optional): JSON processing via x-cmd --- ## More: https://x-cmd.com/llms.txt Entrance for AI agents.
