Results for: "OptionParser"

Parse the YAML document contained in yaml. Events will be called on the handler set on the parser instance.

See Psych::Parser and Psych::Parser#handler

Starts the parser. init is a data accumulator and is passed to the next event handler (as of Enumerable#inject).

Returns the type library version.

tlib = WIN32OLE_TYPELIB.new('Microsoft Excel 9.0 Object Library')
puts tlib.version #-> "1.3"

Parse a raw cookie string into a hash of cookie-name=>Cookie pairs.

cookies = CGI::Cookie.parse("raw_cookie_string")
  # { "name1" => cookie1, "name2" => cookie2, ... }

Create a DRbUnknownError exception containing this object.

Returns true; retained for compatibility.

Parse the source and return the result.

Version of the gem

Override to display a longer description of what this command does.

The Requirement of the unresolved dependency (not Version).

Parse obj, returning an [op, version] pair. obj can be a String or a Gem::Version.

If obj is a String, it can be either a full requirement specification, like ">= 1.2", or a simple version number, like "1.2".

parse("> 1.0")                 # => [">", Gem::Version.new("1.0")]
parse("1.0")                   # => ["=", Gem::Version.new("1.0")]
parse(Gem::Version.new("1.0")) # => ["=,  Gem::Version.new("1.0")]

A string representation of this Version.

Parses uri, raising if it’s invalid

Parses uri, returning the original uri if it’s invalid

Args

uri

String

Description

Parses uri and constructs either matching URI scheme object (File, FTP, HTTP, HTTPS, LDAP, LDAPS, or MailTo) or URI::Generic.

Usage

p = URI::Parser.new
p.parse("ldap://ldap.example.com/dc=example?user=john")
#=> #<URI::LDAP ldap://ldap.example.com/dc=example?user=john>

Args

uri

String

Description

Parses uri and constructs either matching URI scheme object (File, FTP, HTTP, HTTPS, LDAP, LDAPS, or MailTo) or URI::Generic.

Usage

p = URI::Parser.new
p.parse("ldap://ldap.example.com/dc=example?user=john")
#=> #<URI::LDAP ldap://ldap.example.com/dc=example?user=john>

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.

Generate a Table Caption element as a string.

align can be a string, giving the alignment of the caption (one of top, bottom, left, or right). It can be a hash of all the attributes of the element. Or it can be omitted.

The body of the element is provided by the passed-in no-argument block.

caption("left") { "Capital Cities" }
  # => <CAPTION ALIGN=\"left\">Capital Cities</CAPTION>
