用 GPT 写了一个定时保存文件路径的插件

经验分享

由于官方提供的保存新建笔记路径的方法不够灵活，自己用 GPT写了一个插件，可以定时选择一个文件夹，将这段时间内所有新建的笔记都添加在这个文件夹内，定时过了之后将自动恢复保存到根目录中，这样可以很方便解决一个下午或一个晚上只添加某个领域的笔记，不用再重新移动文件夹了，代码可以自己修改设定的时间，以及返回默认的文件夹
main.js

const { Plugin, Notice, TFolder, SuggestModal } = require("obsidian");

class FolderSuggestModal extends SuggestModal {
  constructor(app, getItems, onChoose) {
    super(app);
    this.getItems = getItems;
    this.onChooseCb = onChoose;
    this.setPlaceholder("输入以搜索文件夹…");
  }
  getSuggestions(query) {
    const q = query.toLowerCase();
    return this.getItems().filter(f => f.path.toLowerCase().includes(q));
  }
  renderSuggestion(folder, el) {
    el.createEl("div", { text: folder.path });
  }
  onChooseSuggestion(folder) {
    this.onChooseCb(folder);
  }
}
