Calendar.txt：纯文本日历
Calendar.txt
2022 — 2025，它一次次回到首页

导读
Calendar.txt 介绍了一种用纯文本文件记录日历和待办事项的做法：每一行以日期开头，便于搜索、编辑和纳入版本控制。它更像是一种简单的工作流约定，而不是完整的日历软件。
为什么经久不衰：它击中了人们对简单、可搜索、可版本控制个人数据的需求，也持续引发纯文本工具与成熟日历应用之间如何取舍的讨论。

纯文本格式本身很好，但要真正替代日历软件，还需要同步、重复事件、邀请和通知等软件能力。
作为一种文件格式，这没问题，但我觉得这里把文件格式和用来操作该格式的软件混为一谈了。我用纯文本记账，能用文本编辑器录入并纳入版本控制很好，但下一步还得用 hledger 或 beancount 处理数据。纯文本日历也需要桌面和移动端操作、自动处理重复事件、邀请他人并跟踪接受或拒绝、更新取消改期时通知他人等软件能力。calendar.txt 也许能扮演角色，但单靠它不够。

As a file format, this is just fine, but I feel like there's some conflation between a file format and software meant to interact with that format. I use plain text accounting for my business, and it's lovely to be able to enter bookkeeping data with a plain text editor and keep it all under version control, but the next step is using a program such as hledger or beancount to work with that data. I'd love to work with plain text calendar software, but it would still need to do things such as provide a mechanism to work on my desktop and mobile device. It would need to handle recurring events automatically, and it would need to allow me to invite others to events and ideally to track when they've accepted or rejected my invites. I'd need to be able to update, cancel or propose to move events in such a way that others would be updated. I wish I knew of a good command line tool to interact with CalDav or similar servers, or that I could maintain my calendar in a file format and then handle the synchronization automatically. Maybe calendar.txt could play a role in that, but on its own, it's not quite enough for me.
日期前缀便于搜索，但不支持子列表和详细笔记，是实践中的主要权衡。
我工作日志也类似：用 shell 别名在 vim 里打开按月 markdown 文件，用宏生成日期并记录工作内容。我挺喜欢 calendar.txt 每行加日期前缀，因为 grep 更容易；但它不能做子列表和更详细的笔记。不过用 grep 上下文搜索也够用，还没成为大问题。

I do something similar for daily notes for work. I have a shell alias `tdw` for `TODO work` which opens a YYYY-MM.md file in vim. Inside of that markdown file I use a vim macro that generates a date similar to what is shown in calendar.txt, where I take notes about what I am working on and what I have worked on. Here's ane example of what it looks like: ## 2025-02-27 W09 Thursday - Team standup - Looking up flights to Venus - Meeting with Acme - Discuss hydrocoptic marzlevanes - TODO: read up on them <http://example.com/docs/hydrocoptic-marzlevanes> - (personal) Feed the dragon - #5934 Fix glitch in dingle arm reciprocator I kind of like the calendar.txt idea of prefixing every line with the date, because it makes grepping easier, but at the same time, it doesn't allow for sub-lists and more detailed notes about what was worked on. It hasn't been a big enough problem to deal with though, because of things like `grep -i -B10 encabulator` The vim macro I use is: " Macro To Do Today nmap mtdt <esc>O<CR><esc>k"=strftime('## %F W%V %A')<CR>Pa<CR><CR>-
移动端与电脑之间的同步是纯文本日历落地的主要障碍。
对我来说，用纯文本格式记录日常最大的障碍是需要一个好的移动端与笔记本同步方法，能在两端轻松读写和管理文件。有推荐吗？目前最好想到 SimpleNote，但能否真正用 .txt 文件，而不是把文本存在数据库里？

To me the biggest block for using any plain text format for daily stuff is I need a good mobile - laptop sync method that I can easily read / write and manage files on both mobile and laptop, does anyone have any recommendation? The best choice I can think right now is SimpleNote which I've been using for notes for a long time, but is there a way I can actually use .txt file instead of text been stored somewhere in a database.
纯文本的简单可能牺牲通知、地图、多设备同步等成熟集成带来的便利。
日历应用现在很复杂，且与生产力应用紧密集成，我不确定简单性的收益能抵消失去集成的成本。Google 日历有邮件通知、桌面应用、地图集成、自动填地址、时区调整、多设备同步、文本或拖拽编辑等；Apple 日历大概类似。我的待办也从 org mode 转到了 Google Tasks，因为 Android 和 Google Calendar 的集成。

Calendar apps are so complicated and tightly integrated with other productivity apps now I'm not sure the benefit of simplicity here outweighs the cost of losing that. My Google cal emails me notifications, works with desktop calendar apps, integrates with Maps, etc. It autofills addresses, adjusts for time zones, syncs across my 4000 devices, allows me to edits dates via text input or GUI/drag 'n drop, etc. (Not shilling, Apple cal is probably similar.) Even my todo list went from org mode to Google Tasks because of the integrations with Android, Google Calendar, etc.
