Reducing technical debt from feature flags Read time: 16 minutes Last edited: Oct 15, 2024 Overview This guide provides ways to reduce and eliminate technical debt related to feature flags using LaunchDarkly. Like all debt, technical debt accumulates over time, but you can mitigate that debt over time if you put effective processes in place before you need them. In this guide, we’ll explore: The challenge of technical debt The lifecycle of a flag Naming conventions Using tags Code references Deprecating, archiving, and deleting flags Just like feature flags should be a core engineering practice, so should a strategy to address technical debt. LaunchDarkly can help you by automatically identifying flags that need code removal or are ready to archive. ...

什么是特性管理？ 特性管理是由特性标志（feature flags）驱动的一类新的软件开发工具和技术。一个特性标志是代码中的一个控制杠杆（一个_if-else_语句），它将代码部署与特性发布解耦。开发者多年来一直在使用特性标志的一些变体。但是，当涉及到享受特性标志的全部好处时，许多人只是触及了表面。 ...

What is feature management? Feature management is a new class of software development tools and techniques powered by feature flags. A feature flag is a lever of control within your code (an if-else statement) that decouples code deployments from feature releases. Developers have used some variation of feature flags for years. But when it comes to enjoying the full benefits of feature flags, many have only scratched the surface. At most organizations, the art of feature flagging is confined to just a few teams across a few use cases. Such limits stem, in part, from the fact that managing feature flags at scale is quite challenging. For one thing, technical debt can rapidly accrue if you start using flags in large volumes. As a result, only a handful of developers end up using them, thus limiting the value an organization can capture from those flags (see what we did there?). Another drawback of conventional flags is they only support basic true-false, or Boolean, use cases. This, too, prevents organizations from realizing the full benefits of feature flags. ...

拆分为两套代码所存在的问题： 使用不同分支后，大型修改的合并将变得极为困难，不论是从上游合并到下游，还是下游合并到上游，都将成为一个耗时巨大的工程，以轻共享代码合并上游为例，历时3个多月，经历过大量测试，仍然出现风险不可控。如果只是禁绝了从下游合并到上游的可能，下游的客户也一样需要承担上游合并到下游所带来的功能异常风险，及下游代码丢失的风险，该风险从宏观和微观层面，都与下游合并至上游一致。 ...

如何键入真正的Tab字符？ 如果你想要在 Vim 中输入真正的 Tab 字符，你可以在插入模式下按 Ctrl-V，然后按 Tab。这将插入一个真正的 Tab 字符，而不是空格。 注释代码？ 快捷注释， V gc 如何缩进？ 在 Neovim 中，您可以使用以下方法进行代码缩进： ...
