本地文件和AU答案之间的代码版本控制

介绍

请注意，这是一个“分享知识”的自我回答的问题。

在我的系统上下载与源代码（脚本）链接的Ask Ubuntu答案需要“仅限bash”脚本。 然后使用diff命令比较两者。

关键是要发现我的代码是否已被更改并且AU答案需要更新，或者有人修改了我发布的AU答案，我需要将这些更改滚动到我的代码中。

Answer 1

websync脚本

 #!/bin/bash # NAME: websync # Must have the yad package. command -v yad >/dev/null 2>&1 || { echo >&2 \ "yad package required but it is not installed.

spawn-progress-multi脚本

如果您没有在路径中放置spawn-progress-multi文件，则websync将无法运行它

Answer 2

介绍

由于Ask Ubuntu（AU）答案的32KB大小限制，此解决方案分为多个答案。

第一部分为用户指南提供屏幕截图和字段说明。

下一节提供了完成工作的bash脚本。

概观

所有Ask Ubuntu（AU）答案都以HTML（超文本标记语言）格式存储。 这个应用程序可以在所有Stack Exchange（SE）站点上运行，但它只有AU测试才有很高的可信度。

该申请将：

• 提取问题标题
• 提取问题upvotes
• 提取答案upvotes
• 提取与前三行包含代码的链接文件名匹配的SE代码
• 在SE代码和本地代码之间运行diff命令，在gedit显示结果。
• 显示进度条
• 易于使用的GUI，没有终端要求
• 除了复制bash脚本之外没有其他安装
• 将样本数据附加到磁盘上的现有文件（Ubuntu 16.04）和现有答案。

示例主窗口

这个演示屏必须快节奏，帧减少到2MB文件限制。 它显示首次运行脚本时创建的默认数据。 这是发生了什么：

• 选择第二个条目
• 单击“ Update按钮
• wget从Stack Exchange下载问题和答案，简要介绍进度条。
• 分析问题和答案，并显示进度条约3秒钟。
• diff命令将本地代码~/.bashrc与Stack Exchange上的答案进行比较， gedit用于显示差异。

这是动画结束后遗漏的内容：

gedit用于显示本地代码~/.bashrc与堆栈交换答案之间的差异。

关闭gedit ，主屏幕重新出现，现在填写了问题 – 投票，回答 – 投票和问题标题字段。

让我们通过单击“ View按钮向下钻取

在这里，您可以看到主屏幕上不适合的条目的所有字段。 您可以将堆栈交换网站地址复制到clipbaord，然后将其粘贴到浏览器中。 您可以查看系统上存储的代码文件的上次修改日期。

“ 状态”字段可以包含：

• Update – 添加了新条目或更改了现有条目。 必须单击“更新”按钮以清除标记为更新的所有字段，并使用Stack Exchange中的实际值进行设置。
• Bad file – 指定的文件名不再存在。
• Empty file – 指定的文件名为零字节。
• 3 lines not found – 在Stack Exchange答案中找不到指定文件的前三行（跳过空行）。 输入了错误的文件名或提供了错误的堆栈交换答案，或者文件已更改，使前三行不再匹配。
• Bad Answer – 网站地址不存在。
• Answer < 1K - 网站地址存在但答案的大小不到1 KB。
• Different - 本地代码文件和Stack Exchange Answer有差异。
• Matches - 本地代码文件与堆栈交换答案答案匹配。
• Diff parameter Error - 用于调用diff命令的参数包含一个或多个错误。 使用man diff查看有效选项。

项目范围

主要目的是找出其他人已修改的答案，并将这些更改滚动到本地代码文件中。 另一个目的是找出在本地发生编码更改后需要更新Stack Exchange中的哪些答案。 最后，可以通过答案投票的跟踪来追踪“热门”答案。

不应使用SQL数据库。 只能使用out-of-the-box-bash文件。 应用程序必须使用yad作为GUI用户界面。 Zenity太有限，因为它无法在表单中显示原始值，在数据库太宽时无法隐藏列，并且不允许添加按钮来控制程序流。

解释上面显示的示例主窗口，它显示包含以下内容的可滚动条目：

• 用于选择条目的单选按钮
• 包含代码的本地文件名
• 回答Up-votes（你发布的代码和书面答案正在收集）
• 提问 - （表示全球对此SE问题的兴趣）
• 问题标题

主窗口按钮的摘要是：

• View - 查看所选条目。
• Insert before - 在所选条目Insert before插入新条目。
• Edit - 编辑所选条目。
• Delete - 删除选择条目（需要确认）。
• Update - 从Stack Exchange下载答案并进行分析。
• Cancel ALL - 取消所有更改（如果已进行更改，则需要确认）。 退出键或窗口上的X具有相同的效果。
• Save - 将更改保存到磁盘。

“ View和“ Delete按钮会弹出如上所示的同一窗口。

“ Insert before和“ Edit按钮会弹出类似的窗口，但某些字段未输入并使用“更新”进行初始化。 这表示需要单击主窗口上的“ Update按钮以便稍后从Stack Exchange检索数据。 非输入字段是：文件日期，状态，答案向上投票，提问题和标题。

---

2017年6月更新

修改了代码，以便在保存更改时按问题标题+本地文件名对数组条目进行排序。 不再需要按顺序手动插入记录。

您现在可以通过单击update按钮update all而不选择特定记录。 更新时，所有文件比较都会汇总到一个文件中，并在完成后由gedit显示。 具有相同源代码的答案不会在中断流程的对话框中显示，而是作为状态行放在diff文件中。

为按钮提供加速键。 按住Alt键 ，然后点击要选择的按钮的第一个字母。

sed需要3秒才能将HTML更改为文本太长时间。 它被内置的bash搜索和替换取代，时间现在是一秒或更短。

不幸的是，这些代码更改对于Ask Ubuntu发布来说太长了2000个字符，所以如果您想要一份代码，请留下评论，我会找到一些地方给您发布。
