abstract class ArcanistXHPASTLintNamingHook

You can extend this class and set xhpast.naminghook in your .arclint to have an opportunity to override lint results for symbol names.

Tasks

Overriding Symbol Name Lint Messages

abstract public function lintSymbolName($type, $name, $default) — Callback invoked for each symbol, which can override the default determination of name validity or accept it by returning $default. The symbol types are: xhp-class, class, interface, function, method, parameter, constant, and member.

Name Utilities

public static function isUpperCamelCase($symbol) — Returns true if a symbol name is UpperCamelCase.
public static function isLowerCamelCase($symbol) — Returns true if a symbol name is lowerCamelCase.
public static function isUppercaseWithUnderscores($symbol) — Returns true if a symbol name is UPPERCASE_WITH_UNDERSCORES.
public static function isLowercaseWithUnderscores($symbol) — Returns true if a symbol name is lowercase_with_underscores.
public static function stripPHPFunction($symbol) — Strip non-name components from PHP function symbols. Notably, this discards the "__" magic-method signifier, to make a symbol appropriate for testing with methods like @{method:isLowerCamelCase}.
public static function stripPHPVariable($symbol) — Strip non-name components from PHP variable symbols. Notably, this discards the "$", to make a symbol appropriate for testing with methods like @{method:isLowercaseWithUnderscores}.

public function getPhobjectClassConstant($key, $byte_limit)
Inherited

Phobject

Read the value of a class constant.

This is the same as just typing self::CONSTANTNAME, but throws a more useful message if the constant is not defined and allows the constant to be limited to a maximum length.

Parameters

string	$key	Name of the constant.
int\|null	$byte_limit	Maximum number of bytes permitted in the value.

Return

string

Value of the constant.

final public function __construct()

The constructor is final because ArcanistXHPASTLinter is responsible for hook instantiation.

Return

this	//Implicit.//

abstract public function lintSymbolName($type, $name, $default)

Callback invoked for each symbol, which can override the default determination of name validity or accept it by returning $default. The symbol types are: xhp-class, class, interface, function, method, parameter, constant, and member.

For example, if you want to ban all symbols with "quack" in them and otherwise accept all the defaults, except allow any naming convention for methods with "duck" in them, you might implement the method like this:

if (preg_match('/quack/i', $name)) {
  return 'Symbol names containing "quack" are forbidden.';
}
if ($type == 'method' && preg_match('/duck/i', $name)) {
  return null; // Always accept.
}
return $default;

Parameters

string	$type	The symbol type.
string	$name	The symbol name.
string\|null	$default	The default result from the main rule engine.

Return

string|null

Null to accept the name, or a message to reject it with. You should return the default value if you don't want to specifically provide an override.

public static function isUpperCamelCase($symbol)

Returns true if a symbol name is UpperCamelCase.

Parameters

string

$symbol

Symbol name.

Return

bool	True if the symbol is UpperCamelCase.

public static function isLowerCamelCase($symbol)

Returns true if a symbol name is lowerCamelCase.

Parameters

string

$symbol

Symbol name.

Return

bool	True if the symbol is lowerCamelCase.

public static function isUppercaseWithUnderscores($symbol)

Returns true if a symbol name is UPPERCASE_WITH_UNDERSCORES.

Parameters

string

$symbol

Symbol name.

Return

bool	True if the symbol is UPPERCASE_WITH_UNDERSCORES.

public static function isLowercaseWithUnderscores($symbol)

Returns true if a symbol name is lowercase_with_underscores.

Parameters

string

$symbol

Symbol name.

Return

bool	True if the symbol is lowercase_with_underscores.

public static function stripPHPFunction($symbol)

Strip non-name components from PHP function symbols. Notably, this discards the "__" magic-method signifier, to make a symbol appropriate for testing with methods like isLowerCamelCase().

Parameters

string

$symbol

Symbol name.

Return

string

Stripped symbol.

public static function stripPHPVariable($symbol)

Strip non-name components from PHP variable symbols. Notably, this discards the "$", to make a symbol appropriate for testing with methods like isLowercaseWithUnderscores().

Parameters

string

$symbol

Symbol name.

Return

string

Stripped symbol.
