下载Pixiv图片到Eagle

可根据需求自行修改代码中设置项。在Pixiv上添加可以导入图片到Eagle的下载按钮,默认保存所有标签以及标签翻译,以创作者名创建文件夹保存,能力有限暂无法处理动图。首页、排行榜、关注用户新作品页、收藏页添加下载按钮,添加复选框。自动将用户id添加进文件夹注释,同名文件夹注释中不存在id则更新注释添加id,尽量避免添加进同名不同id文件夹中

// 本次更新新增:新增排行榜下载按键,在最新版eagle中可创建指定位置的子文件夹
// 修复:修复低版本eagle会报错的问题,修复重复创建文件夹的bug

// 注意!因收藏页的复选框影响了原网页正常功能,现已将下载按键合并入“管理收藏”的功能中!
// 似乎已经无影响了,小改动修复从收藏页跳转出去脚本不会执行的问题
// pixiv的网站前端仍在频繁更新中,脚本随时可能失效

// 设置项
const patt = / *[@@◆■◇☆⭐️🌟🦇💎🔞🍅🌱🐻🍬::\\\/].*/; // 处理作者名多余后缀的正则
const saveTags = true; // 是否保存标签
const tagAuthor = true; // 是否将作者名加入标签
const addToFavor = true; // 下载时是否同时加入收藏
const searchDirName = ""; // 在判断是否需要创建文件夹时,限定搜索和新建子文件夹的位置,在引号内输入文件夹名,该文件夹应当不存在父文件夹。留空则搜索全部
let   searchDirId = ""; // 一般无需填写,上一行所指定文件夹的id(eagle中选中文件夹右键复制链接,获得如‘eagle://folder/K4130PELEY5W9’字符串,文件夹id就是其中K4130PELEY5W9部分)。填写会使上一行设置失效,可用来设置为新建文件夹创建到某个子文件夹中。
const enableNewIllust = true; // 关注用户新作品页面添加下载按钮
const useCheckbox = true; // 为true时在每一张图上添加复选框代替下载键,此时下载键将移至图片所在区域上方标题处
