ext-variable-name

This rule provides extensive support for customizing allowable variable names for a wide variety of variable tags. The rule is configured by setting up a list of sub-rules that specify the tags of variables to check and the checks to perform on the variable"s name. The sub-rules are checked in order and the first one that matches the tags of variable being checked is the only one that is used.

An example set of sub-rules for an example coding standard is shown below.

Rationale:

Usage:

{
	"ext-variable-name": [
		true,
		[
			"class",
			"pascal"
		],
		[
			"interface",
			"pascal",
			{
				"regex": "^I.*$"
			}
		],
		[
			"parameter",
			"camel"
		],
		[
			"property",
			"static",
			"camel",
			{
				"regex": "^s.*$"
			}
		],
		[
			"property",
			"private",
			"camel",
			"allow-leading-underscore"
		],
		[
			"property",
			"protected",
			"camel",
			"allow-leading-underscore"
		],
		[
			"variable",
			"local",
			"snake"
		],
		[
			"variable",
			"const",
			"upper"
		],
		[
			"variable",
			"camel",
			{
				"regex": "^g.*$"
			}
		],
		[
			"method",
			"private",
			"camel",
			"allow-leading-underscore"
		],
		[
			"method",
			"protected",
			"camel",
			"allow-leading-underscore"
		],
		[
			"function",
			"camel"
		],
		[
			"default",
			"camel"
		]
	]
}

Options:

• primary (choose one):
• class, interface, parameter, property, method, function, variable

note: If any tags is added to a sub-rule then all must match the variable.

Checks allowed:

• One of:
• "camel": Require variables to use camelCaseVariables
• "snake": Require variables to use snake_case_variables
• "pascal": Require variables to use PascalCaseVariables
• "upper": Require variables to use UPPER_CASE_VARIABLES
• "allow-leading-underscore": permits the variable to have a leading underscore
• "allow-trailing-underscore": permits the variable to have a trailing underscore
• "ban-keywords": bans a list of language keywords from being used
• {"regex": "^.*$"}: checks the variable name against the given regex
