Parses uri, raising if it’s invalid
Parses uri, returning the original uri if it’s invalid
Returns the parser to be used.
Unless a URI::Parser is defined, DEFAULT_PARSER is used.
Returns true if URI does not have a scheme (e.g. http:// or https://) specified.
Returns extensions.
Setter for extensions val.
uri
Parses uri and constructs either matching URI scheme object (File, FTP, HTTP, HTTPS, LDAP, LDAPS, or MailTo) or URI::Generic.
p = URI::Parser.new p.parse("ldap://ldap.example.com/dc=example?user=john") #=> #<URI::LDAP ldap://ldap.example.com/dc=example?user=john>
uri
Parses uri and constructs either matching URI scheme object (File, FTP, HTTP, HTTPS, LDAP, LDAPS, or MailTo) or URI::Generic.
p = URI::Parser.new p.parse("ldap://ldap.example.com/dc=example?user=john") #=> #<URI::LDAP ldap://ldap.example.com/dc=example?user=john>
Returns the conversion path of ec.
The result is an array of conversions.
ec = Encoding::Converter.new("ISO-8859-1", "EUC-JP", crlf_newline: true) p ec.convpath #=> [[#<Encoding:ISO-8859-1>, #<Encoding:UTF-8>], # [#<Encoding:UTF-8>, #<Encoding:EUC-JP>], # "crlf_newline"]
Each element of the array is a pair of encodings or a string. A pair means an encoding conversion. A string means a decorator.
In the above example, [#<Encoding:ISO-8859-1>,
Convert source_string and return destination_string.
source_string is assumed as a part of source. i.e. :partial_input=>true is specified internally. finish method should be used last.
ec = Encoding::Converter.new("utf-8", "euc-jp") puts ec.convert("\u3042").dump #=> "\xA4\xA2" puts ec.finish.dump #=> "" ec = Encoding::Converter.new("euc-jp", "utf-8") puts ec.convert("\xA4").dump #=> "" puts ec.convert("\xA2").dump #=> "\xE3\x81\x82" puts ec.finish.dump #=> "" ec = Encoding::Converter.new("utf-8", "iso-2022-jp") puts ec.convert("\xE3").dump #=> "".force_encoding("ISO-2022-JP") puts ec.convert("\x81").dump #=> "".force_encoding("ISO-2022-JP") puts ec.convert("\x82").dump #=> "\e$B$\"".force_encoding("ISO-2022-JP") puts ec.finish.dump #=> "\e(B".force_encoding("ISO-2022-JP")
If a conversion error occur, Encoding::UndefinedConversionError or Encoding::InvalidByteSequenceError is raised. Encoding::Converter#convert doesn’t supply methods to recover or restart from these exceptions. When you want to handle these conversion errors, use Encoding::Converter#primitive_convert.
Parses the given string into an abstract syntax tree, returning the root node of that tree.
RubyVM::AbstractSyntaxTree.parse("x = 1 + 2") # => #<RubyVM::AbstractSyntaxTree::Node:SCOPE@1:0-1:9>
If keep_script_lines: true option is provided, the text of the parsed source is associated with nodes and is available via Node#script_lines.
If keep_tokens: true option is provided, Node#tokens are populated.
SyntaxError is raised if the given string is invalid syntax. To overwrite this behavior, error_tolerant: true can be provided. In this case, the parser will produce a tree where expressions with syntax errors would be represented by Node with type=:ERROR.
root = RubyVM::AbstractSyntaxTree.parse("x = 1; p(x; y=2") # <internal:ast>:33:in `parse': syntax error, unexpected ';', expecting ')' (SyntaxError) # x = 1; p(x; y=2 # ^ root = RubyVM::AbstractSyntaxTree.parse("x = 1; p(x; y=2", error_tolerant: true) # (SCOPE@1:0-1:15 # tbl: [:x, :y] # args: nil # body: (BLOCK@1:0-1:15 (LASGN@1:0-1:5 :x (LIT@1:4-1:5 1)) (ERROR@1:7-1:11) (LASGN@1:12-1:15 :y (LIT@1:14-1:15 2)))) root.children.last.children # [(LASGN@1:0-1:5 :x (LIT@1:4-1:5 1)), # (ERROR@1:7-1:11), # (LASGN@1:12-1:15 :y (LIT@1:14-1:15 2))]
Note that parsing continues even after the errored expression.
Creates a class to wrap the C union described by signature.
MyUnion = union ['int i', 'char c']
