Plain clicks still open file paths. Pass **`--no-drag-copy`** to disable that and use the Scroll/Select mouse-mode toggle (Shift+Tab) instead — a fallback for terminals where drag-copy misbehaves. +- **Cross-platform CI** — the test suite now runs on Linux, macOS, and Windows across Python 3.10–3.13. + +### Changed + +- **Boolean options validate at parse time** — `--render-js`, `--screenshot`, `--premium-proxy`, `--json-response`, and every other true/false option now reject a missing or non-boolean value (e.g. `--render-js --output-file x`, or a typo like `treu`) with a clear *"Invalid boolean … Use true/false, 1/0, or yes/no"* instead of the misleading *"unexpected extra argument"*. `--help` shows these as `TRUE|FALSE`. Accepted values are unchanged. + +### Fixed + +- **Onboarding `:q` trap (REPL)** — at the first-run "API key:" prompt, `:q`/`quit`/`exit` now quit as advertised instead of being validated as an API key. +- **Validation order** — `google`, `fast-search`, `chatgpt`, `amazon-*`, `youtube-*`, and `walmart-*` now report a missing required argument before "API key not set", matching `scrape`. +- **`schedule`/`unsafe` subcommand-style typos** — `schedule list` / `unsafe status` (and similar) now show a "did you mean `--list` / `--audit` / …" hint instead of a confusing error. +- **`schedule` on Windows** — `schedule --every …` / `--stop …` now fail with a clean "scheduling requires cron (macOS/Linux)" message instead of a raw `FileNotFoundError` when `crontab` is absent. +- **Crawl reported false success when `--save-pattern` matched nothing** — a crawl whose `--save-pattern` matched no page printed `Saved to ` and exited 0 while creating no output directory, `manifest.json`, or `.batch_meta.json`, so credits were spent on discovery with nothing to show and scripts checking for the output dir broke. The spider now always creates the directory and writes a manifest (empty when nothing matched) plus batch metadata, and the CLI reports honestly — `No pages saved to — no crawled URL matched --save-pattern '…'. Discovery still used credits.`, or `Saved to (N of up to M pages matched …)` when fewer than `--max-pages` matched. +- **Crawl saved `/index.html` and `/` as duplicates** — a site serving the same page at both `/` and `/index.html` (or `…/foo/` and `…/foo/index.html`) was crawled and saved twice — double credits and inflated manifest counts. `_normalize_url` now collapses a trailing directory-index file (`index.html` / `index.htm`) to its directory so the two forms deduplicate to a single save. +- **`crawl --resume` overwrote the previous manifest** — resuming a crawl rewrote `manifest.json` with only the new run's saves, dropping the earlier run's entries. The spider now seeds its URL→file map from the existing manifest so resume merges instead of clobbering. +- **REPL crashed at startup on Python 3.10 / 3.11** — the `asyncio.run` shim always passed `loop_factory=` (a Python 3.12+ argument), so launching `scrapingbee` raised `TypeError` immediately on 3.10/3.11. The shim now branches on the interpreter version. +- **Screenshot crawls broke on Scrapy 2.16** — Scrapy 2.16 stopped calling `start_requests()`, so screenshot / extract / AI crawls silently fell back to a raw direct fetch of the seed URL (a corrupt artifact). The spider now defines the supported `async start()` entry point, so the ScrapingBee discovery flow runs for every crawled page. + ## [1.4.4] - 2026-06-22 ### Added diff --git a/README.md b/README.md index 95434f3..4fb7a11 100644 --- a/README.md +++ b/README.md @@ -5,6 +5,7 @@ Command-line client for the [ScrapingBee](https://www.scrapingbee.com/) API: scr ## Requirements - **Python 3.10+** +- **Linux:** clipboard copy (e.g. selecting text in the interactive REPL's `:view` pager) needs one of `wl-copy`, `xclip`, or `xsel` installed. macOS (`pbcopy`) and Windows (`clip`) work out of the box. **Setup:** Install (below), then authenticate (Configuration).

Works with `scrape`, `crawl`, and batch mode. - **CSS/XPath extraction:** `--extract-rules '{"title": "h1", "price": ".price"}'` for consistent, cheaper production scraping. Find selectors in browser DevTools. - **Pipelines:** Chain commands with `--extract-field` — e.g. `google QUERY --extract-field organic_results.url > urls.txt` then `scrape --input-file urls.txt`. Use `--fields` to filter JSON output keys; supports dot notation (e.g. `--fields product.title,product.price`). - **Smart Extract:** `--smart-extract` extracts data from any format (JSON, HTML, XML, CSV, Markdown) using a path expression. Auto-detects format. Supports slicing, regex filtering, and JSON schema output. - **Update CSV:** `--update-csv` fetches fresh data and updates the input CSV in-place.

Note: `--max-pages` caps *saved* pages, so with `--save-pattern` (or AI/screenshot/extract modes) the crawl fetches additional pages to find matches and total credits can exceed `--max-pages`. - **Output formats:** `--output-format` accepts `ndjson` (streams results as JSON lines) or `csv` (writes a single CSV) — these are the only valid values. Default (no flag) writes individual files per item into `--output-dir`. - **CSV input:** `--input-file products.csv --input-column url` reads URLs from a CSV column. - **Export:** `scrapingbee export --input-dir batch/ --format csv --flatten --columns "title,price"` merges batch output with nested JSON flattening and column selection. diff --git a/plugins/scrapingbee-cli/.claude-plugin/plugin.json b/plugins/scrapingbee-cli/.claude-plugin/plugin.json index 5fec453..15837b6 100644 --- a/plugins/scrapingbee-cli/.claude-plugin/plugin.json +++ b/plugins/scrapingbee-cli/.claude-plugin/plugin.json @@ -1,7 +1,7 @@ { "name": "scrapingbee", "description": "The best web scraping tool for LLMs. USE --smart-extract to give your AI agent only the data it needs from any web page — extracts from JSON/HTML/XML/CSV/Markdown using path language with recursive search, filters, and regex.
