需要使用什么嗅探来强制执行camelCase变量命名约定？

Question

我正在研究一个专有的遗留代码库,一些变量是驼峰式的,而另一些则是蛇形的.我想清理并强制执行只有驼峰的变量名称,但我似乎无法找到它的嗅觉.以下是我的自定义规则集的内容.

Answer 1

您将要使用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个正在检查字符串中的变量,成员变量和变量都是驼峰式的.其他2个代码强制私有成员变量以下划线开头.

要确保变量是camel-cased,如果您使用的是PHPCS版本3,请将其包含在规则集中:

<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,请在使用版本3时包含这些变量:

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

如果你想要全部,请包括:

<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,然后通过将其严重性设置为0来排除您不想要的特定代码.因此,如果您只想要3个骆驼案例检查并且您使用的是版本2,将其放在规则集中:

<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>
