需要使用什么 sniff 来强制执行驼峰式变量命名约定?

What sniff needs to be used to enforce a camelCase variable naming convention?

我正在处理一个专有的遗留代码库,一些变量是驼峰式的,而另一些是蛇形的。我想清理并仅强制执行驼峰变量名,但我似乎无法找到它的嗅探。这是我的自定义规则集的内容。

The ruleset.xml standard contains 68 sniffs

您需要使用 Squiz.NamingConventions.ValidVariableName 嗅探来检查变量名称。

此嗅探当前包含 5 个不同的错误代码。其中 3 个正在检查变量、成员变量和字符串中的变量是否都是驼峰式的。其他 2 个代码强制私有成员变量以下划线开头。

如果您使用的是 PHPCS 版本 3,为了确保变量是驼峰式大小写,请将其包含在您的规则集中:

<rule ref="Squiz.NamingConventions.ValidVariableName.NotCamelCaps"/>

如果您还想确保成员变量和字符串变量是驼峰式的,如果您使用的是版本 3,请包括这些:

<rule ref="Squiz.NamingConventions.ValidVariableName.MemberNotCamelCaps"/>
<rule ref="Squiz.NamingConventions.ValidVariableName.StringNotCamelCaps"/>

如果你想要全部,包括这个:

<rule ref="Squiz.NamingConventions.ValidVariableName"/>

PHPCS 版本 2 不允许您包含特定的嗅探代码,因此您首先需要包含整个嗅探代码,然后通过将它们的严重性设置为 0 来排除不需要的特定代码。因此,如果您只想3 个驼峰式检查并且您使用的是版本 2,将其放入您的规则集中:

<rule ref="Squiz.NamingConventions.ValidVariableName"/>
<rule ref="Squiz.NamingConventions.ValidVariableName.PublicHasUnderscore">
    <severity>0</severity>
</rule>
<rule ref="Squiz.NamingConventions.ValidVariableName.PrivateNoUnderscore">
    <severity>0</severity>
</rule>
