在 MySQL 中编辑命令行 Anki 抽认卡

Question

我需要在 77777 Anki抽认卡中做一个小的改变，优先以编程方式，而不是通过使用它们的替换工具是不够的。我最初将数据导入为 CSV 文件，其中数据易于修改。我从他们的支持那里得到了答案：他们使用 MySQL 作为数据库：

好吧，对于初学者来说，我假设人们需要了解读取和写入 MySQL 数据库。如果这不是你知道的事情，我会就此打住。

例如，我想知道他们的数据库架构。我想在一个 Deck 上运行的示例伪命令

sed s/;/1)/ [anki-deck's-cards]

其中仅匹配换行符的第一个条目。实际上，要求是做一些简单的算术运算。我不知道他们的 MySQL 的连接器详细信息。我想了解一下他们的 MySQL 详细信息。

如何在 Anki Flashcards 的 Deck 中编辑卡片？

Answer 1

apkg 文件包含嵌入的 sqlite 数据库文件。例如，南美首都城市套牌下载为 Capital_Cities_of_South_America.apkg，它实际上是一个 zip 文件。解压该文件会解压出几个文件

$ unzip ../Capital_Cities_of_South_America.apkg
Archive:  ../Capital_Cities_of_South_America.apkg

但有趣的是collection.anki2，它是一个sqlite 文件。

$ sqlite3 collection.anki2

此时，您可以使用标准 sql 命令自由更新条目。
