Diviner Arcanist Tech Docs PhutilSimpleOptionsLexer

final class PhutilSimpleOptionsLexer
Arcanist Technical Documentation ()

Lexer for simple options, like:

eyes=2, legs=4

Values may be quoted and escaped:

eyes="one, or two", legs="{^,\",^}"

Tasks

Lexer Implementation

protected function getRawRules()

Lexer Rules

protected function getRules() — Process, normalize, and validate the raw lexer rules.

Lexer Tokens

public function getTokens($input, $initial_state) — Lex an input string into tokens.

Other Methods

public function __get($name)
public function __set($name, $value)
public function current()
public function key()
public function next()
public function rewind()
public function valid()
private function throwOnAttemptedIteration()
public function getPhobjectClassConstant($key, $byte_limit) — Read the value of a class constant.
public function mergeTokens($tokens) — Merge adjacent tokens of the same type. For example, if a comment is tokenized as <"//", "comment">, this method will merge the two tokens into a single combined token.
public function getLexerState()
public function getNiceTokens($input)

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.

protected function getRawRules()

PhutilLexer

Return a set of rules for this lexer. See description in PhutilLexer.

Return

dict	Lexer rules.

protected function getRules()
Inherited

Return

wild

public function getTokens($input, $initial_state)
Inherited

PhutilLexer

Lex an input string into tokens.

Parameters

string	$input	Input string.
string	$initial_state	Initial lexer state.

Return

list	List of lexer tokens.

public function mergeTokens($tokens)
Inherited

PhutilLexer

Merge adjacent tokens of the same type. For example, if a comment is tokenized as <"//", "comment">, this method will merge the two tokens into a single combined token.

Parameters

array
