指定浏览器 surface

大多数子命令需要指定目标 surface。可以通过位置参数或 --surface 传入。

# Open a new browser split
cmux browser open https://example.com

# Discover focused IDs and browser metadata
cmux browser identify
cmux browser identify --surface surface:2

# Positional vs flag targeting are equivalent
cmux browser surface:2 url
cmux browser --surface surface:2 url

cmux browser open https://example.com
cmux browser open-split https://news.ycombinator.com

cmux browser surface:2 navigate https://example.org/docs --snapshot-after
cmux browser surface:2 back
cmux browser surface:2 forward
cmux browser surface:2 reload --snapshot-after
cmux browser surface:2 url

cmux browser surface:2 focus-webview
cmux browser surface:2 is-webview-focused

等待

使用 wait 命令阻塞等待，直到选择器、文本、URL 片段、加载状态或 JavaScript 条件满足。

cmux browser surface:2 wait --load-state complete --timeout-ms 15000
cmux browser surface:2 wait --selector "#checkout" --timeout-ms 10000
cmux browser surface:2 wait --text "Order confirmed"
cmux browser surface:2 wait --url-contains "/dashboard"
cmux browser surface:2 wait --function "window.__appReady === true"

DOM 交互

变更操作支持 --snapshot-after 用于脚本中的快速验证。

cmux browser surface:2 click "button[type='submit']" --snapshot-after
cmux browser surface:2 dblclick ".item-row"
cmux browser surface:2 hover "#menu"
cmux browser surface:2 focus "#email"
cmux browser surface:2 check "#terms"
cmux browser surface:2 uncheck "#newsletter"
cmux browser surface:2 scroll-into-view "#pricing"

cmux browser surface:2 type "#search" "cmux"
cmux browser surface:2 fill "#email" --text "ops@example.com"
cmux browser surface:2 fill "#email" --text ""
cmux browser surface:2 press Enter
cmux browser surface:2 keydown Shift
cmux browser surface:2 keyup Shift
cmux browser surface:2 select "#region" "us-east"
cmux browser surface:2 scroll --dy 800 --snapshot-after
cmux browser surface:2 scroll --selector "#log-view" --dx 0 --dy 400

检查

使用结构化 getter 用于脚本，快照/截图用于人工审查。

cmux browser surface:2 snapshot --interactive --compact
cmux browser surface:2 snapshot --selector "main" --max-depth 5
cmux browser surface:2 screenshot --out /tmp/cmux-page.png

cmux browser surface:2 get title
cmux browser surface:2 get url

cmux browser surface:2 get html "main"
cmux browser surface:2 get value "#email"
cmux browser surface:2 get attr "a.primary" --attr href
cmux browser surface:2 get count ".row"
cmux browser surface:2 get box "#checkout"
cmux browser surface:2 get styles "#total" --property color

cmux browser surface:2 is visible "#checkout"
