需要使用哪些嗅探来强制执行camelCase变量命名约定？

Question

我正在使用专有的遗留代码库，有些变量是骆驼壳，而其他变量是蛇形的。我想清理和强制执行只骆驼变量的名称，但我似乎无法找到一个嗅探。以下是我的自定义规则集的内容。

Answer 1

您会想要使用Squiz.NamingConventions.ValidVariableName sniff来检查变量名称。

这嗅探目前包括5个不同的错误代码。其中3人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个代码强制私人成员变量以下划线开头。

如果只想确保变量是骆驼，套管，包括这在你的规则集，如果你正在使用PHPCS版本3：

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

如果你也想确保成员VAR和串瓦尔的骆驼套管，包括这些，如果您使用的版本3：

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

如果你想一大堆，包括此：

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

PHPCS版本2不允许包含特定的嗅探代码，因此您首先需要包括整个嗅探，然后通过将其严重性设置为0来排除您不需要的特定代码。因此，如果您只需要3头骆驼 - 案例检查，你使用的版本2，把这个在你的规则：

<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>
