hexo-extract-excerpt v1.2.0

hexo-extract-excerpt

• Processing flow - If an excerpt is manually specified using <!--more-->, use the content before it as the excerpt. - If no excerpt is specified, extract text from the article (links, images, mermaid diagrams, etc. are ignored) and take the first excerpt_length (default 400, configurable) characters from the beginning of the text. - If the length of the extracted text is less than excerpt_length (i.e., the article is very short), use the entire text as the excerpt and end the processing. Otherwise, take the extracted text as the excerpt text. - (Optional) Extract the first image element from the article based on excerpt_img_selector, and insert the image element at the beginning of the excerpt text to create the final excerpt.
• Configuration - Add the configuration to _config.yml. Default configuration is used if not specified. - excerpt_length is set to 400 by default and can be changed by specifying excerpt_length: 500. - excerpt_img_selector is set to '' by default, which means images are not extracted. It can be configured in any CSS selector format, such as excerpt_img_selector: 'img' (matching the first image element), excerpt_img_selector: 'img, pre.mermaid, figure' (matching the first image element, code block, or mermaid diagram, whichever appears first).

• 处理流程 - 已手动指定摘要时，用 <!--more--> 前面的内容作为摘要 - 没有摘要时，从文章提取文字（链接、图片、mermaid 等内容会被忽略），从文字头部截取 excerpt_length 长度的字数（默认 400，可配置） - 如截取后的长度小于 excerpt_length（文章很短时），则直接使用原文（不生成摘要），处理结束，否则截取部分作为 摘要文本 - （可选）按 excerpt_img_selector 从文章中提取第一个图片元素，并将该元素插入到 摘要文本 前面，成为最终摘要
• 配置 - 配置添加到 _config.yml 中，不配置时使用默认配置 - excerpt_length 默认为 400，可修改 excerpt_length: 500 - excerpt_img_selector 默认为 ''，即不提取图片，可配置成任何 CSS 选择器格式，如 excerpt_img_selector: 'img'（匹配第一个图片元素）， excerpt_img_selector: 'img, pre.mermaid, figure' （匹配第一个图片或代码块或 mermaid，哪个类型先出现用哪个）
