Returns the String created by generating CSV from ary using the specified options.
Argument ary must be an Array.
Special options:
Option :row_sep defaults to $INPUT_RECORD_SEPARATOR ($/).:
$INPUT_RECORD_SEPARATOR # => "\n"
This method accepts an additional option, :encoding, which sets the base Encoding for the output. This method will try to guess your Encoding from the first non-nil field in row, if possible, but you may need to use this parameter as a backup plan.
For other options, see Options for Generating.
Returns the String generated from an Array:
CSV.generate_line(['foo', '0']) # => "foo,0\n"
Raises an exception if ary is not an Array:
# Raises NoMethodError (undefined method `find' for :foo:Symbol) CSV.generate_line(:foo)
Returns true if the date is Wednesday.
Returns true if time represents Wednesday.
t = Time.local(1993, 2, 24) #=> 1993-02-24 00:00:00 -0600 t.wednesday? #=> true
returns array of WIN32OLE_PARAM object corresponding with method parameters.
tobj = WIN32OLE_TYPE.new('Microsoft Excel 9.0 Object Library', 'Workbook')
method = WIN32OLE_METHOD.new(tobj, 'SaveAs')
p method.params # => [Filename, FileFormat, Password, WriteResPassword,
ReadOnlyRecommended, CreateBackup, AccessMode,
ConflictResolution, AddToMru, TextCodepage,
TextVisualLayout]
Argument csv_string, if given, must be a String object; defaults to a new empty String.
Arguments options, if given, should be generating options. See Options for Generating.
Creates a new CSV object via CSV.new(csv_string, **options); calls the block with the CSV object, which the block may modify; returns the String generated from the CSV object.
Note that a passed String is modified by this method. Pass csv_string.dup if the String must be preserved.
This method has one additional option: :encoding, which sets the base Encoding for the output if no no str is specified. CSV needs this hint if you plan to output non-ASCII compatible data.
Add lines:
input_string = "foo,0\nbar,1\nbaz,2\n" output_string = CSV.generate(input_string) do |csv| csv << ['bat', 3] csv << ['bam', 4] end output_string # => "foo,0\nbar,1\nbaz,2\nbat,3\nbam,4\n" input_string # => "foo,0\nbar,1\nbaz,2\nbat,3\nbam,4\n" output_string.equal?(input_string) # => true # Same string, modified
Add lines into new string, preserving old string:
input_string = "foo,0\nbar,1\nbaz,2\n" output_string = CSV.generate(input_string.dup) do |csv| csv << ['bat', 3] csv << ['bam', 4] end output_string # => "foo,0\nbar,1\nbaz,2\nbat,3\nbam,4\n" input_string # => "foo,0\nbar,1\nbaz,2\n" output_string.equal?(input_string) # => false # Different strings
Create lines from nothing:
output_string = CSV.generate do |csv| csv << ['foo', 0] csv << ['bar', 1] csv << ['baz', 2] end output_string # => "foo,0\nbar,1\nbaz,2\n"
Raises an exception if csv_string is not a String object:
# Raises TypeError (no implicit conversion of Integer into String) CSV.generate(0)
Add separator in summary.
Returns the parameter information of this proc.
prc = lambda{|x, y=42, *other|} prc.parameters #=> [[:req, :x], [:opt, :y], [:rest, :other]]
Returns the parameter information of this method.
def foo(bar); end method(:foo).parameters #=> [[:req, :bar]] def foo(bar, baz, bat, &blk); end method(:foo).parameters #=> [[:req, :bar], [:req, :baz], [:req, :bat], [:block, :blk]] def foo(bar, *args); end method(:foo).parameters #=> [[:req, :bar], [:rest, :args]] def foo(bar, baz, *args, &blk); end method(:foo).parameters #=> [[:req, :bar], [:req, :baz], [:rest, :args], [:block, :blk]]
Returns the parameter information of this method.
def foo(bar); end method(:foo).parameters #=> [[:req, :bar]] def foo(bar, baz, bat, &blk); end method(:foo).parameters #=> [[:req, :bar], [:req, :baz], [:req, :bat], [:block, :blk]] def foo(bar, *args); end method(:foo).parameters #=> [[:req, :bar], [:rest, :args]] def foo(bar, baz, *args, &blk); end method(:foo).parameters #=> [[:req, :bar], [:req, :baz], [:rest, :args], [:block, :blk]]
Return the parameters definition of the method or block that the current hook belongs to. Format is the same as for Method#parameters
Returns a String containing the generated JSON data.
See also JSON.fast_generate, JSON.pretty_generate.
Argument obj is the Ruby object to be converted to JSON.
Argument opts, if given, contains a Hash of options for the generation. See Generating Options.
When obj is an Array, returns a String containing a JSON array:
obj = ["foo", 1.0, true, false, nil] json = JSON.generate(obj) json # => '["foo",1.0,true,false,null]'
When obj is a Hash, returns a String containing a JSON object:
obj = {foo: 0, bar: 's', baz: :bat} json = JSON.generate(obj) json # => '{"foo":0,"bar":"s","baz":"bat"}'
For examples of generating from other Ruby objects, see Generating JSON from Other Objects.
Raises an exception if any formatting option is not a String.
Raises an exception if obj contains circular references:
a = []; b = []; a.push(b); b.push(a) # Raises JSON::NestingError (nesting of 100 is too deep): JSON.generate(a)
Changes the parameters of the deflate stream to allow changes between different types of data that require different types of compression. Any unprocessed data is flushed before changing the params.
See Zlib::Deflate.new for a description of level and strategy.
