[Ironruby-core] byte[] to ruby string

Hello,

I''m struggling with converting a byte array into a ruby binary string.
Does anybody know how to make something like this pass?

require ''test/unit''
include System::IO
class Binstring < Test::Unit::TestCase

   def test_binstring_bytea
     fileName = ''flowers.jpg''

     #Ruby way
     data1 = File.read(fileName)

     #.Net
     fs = FileStream.new(fileName, FileMode.Open, FileAccess.Read);
     br = BinaryReader.new(fs);
     numBytes = FileInfo.new(fileName).Length;
     buff = br.ReadBytes(numBytes);
     data2 = System::Text::ASCIIEncoding.new.GetString(buff).to_s

     assert data1 == data2
   end

end

Regards,

H?kon

File.open(filename, ''rb:BINARY) { |f| f.read } might help not sure
though.

You can also look into the unpack method of a string that is used for
returning a bunch of different serialization formats.

[Ironruby-core] byte[] to ruby string

I don''t even get that far. When I do a File.read or a
System::IO::File.read_all_bytes from IronRuby (iirb.exe), I get this (works OK
in MRI):

C:\>iirb
irb(main):001:0> File.read("c:\\temp\\clickhere.png")
File.read("c:\\temp\\clickhere.png")
IOError: Not enough storage is available to process this command.

[Ironruby-core] byte[] to ruby string

The current implementation of to_s is inherited from IList because byte[]
implements IList interface:>>> a = System::Array[System::Byte].new(10)=> [0 (Byte), 0 (Byte), 0 (Byte), 0 (Byte), 0 (Byte), 0 (Byte), 0 (Byte), 0
(Byte), 0 (Byte), 0 (Byte)]>>> a.to_s
=> "0000000000">>> a.method(:to_s)=> #<Method:
System::Byte[](System::Collections::IList)#to_s>>>> a.method(:to_s).clr_members=> [IronRuby.Builtins.MutableString
Join(IronRuby.Runtime.ConversionStorage`1[IronRuby.Builtins.MutableString],
System.Collections.IList)]

Which is not very useful for byte[]. However to keep this consistent with other
arrays it?s better to keep it as is.
To enable creating strings from byte[] I?ll add an overload to String.new that
takes a byte[].
>>> a = System::Array[System::Byte].new(10)=> [0 (Byte), 0 (Byte), 0 (Byte), 0 (Byte), 0 (Byte), 0 (Byte), 0 (Byte), 0
(Byte), 0 (Byte), 0 (Byte)]>>> a[4] = ?A
=> 65>>> String.new(a)=> "\000\000\000\000A\000\000\000\000\000"

You can also go to MutableString class directly like so:>>> String.CreateBinary(a)=> "\000\000\000\000A\000\000\000\000\000"

or>>> String.CreateBinary().Append(a, 3, 3)=> "\000A\000"

[Ironruby-core] byte[] to ruby string

In this particular case, I would recommend to use .NET API:
>>> include System::IO
=> Object>>> stream = FileStream.new("c:\\temp\\a.txt", FileMode.Open,
FileAccess.Read)
=> System.IO.FileStream>>> "".Append(stream, stream.Length)=> "hello"

CreateBinary made the picture file pass the test.

     buff = br.ReadBytes(numBytes)
     data2 = String.CreateBinary(buff)

   def test_2
     fileName = ''flowers.jpg''

     #Ruby
     data1 = File.read(fileName)

     fs = FileStream.new(fileName, FileMode.Open, FileAccess.Read)

[Ironruby-core] byte[] to ruby string

<"This is a test\n"> expected but was
<"This is a test\r\n">.
windows default is to use CRLF for a new line and the CLR inherits that
But for ruby the new line constant is a LF which ruby inherits from *nix
based systems

the dirty workaround is

either specify data0 = "This is a test\r\n"
or
data1.gsub! /\n/, "\r\n"
or
data2.gsub! /\r\n/, "\n"

AFAIK there is no way to override the Environment.NewLine constant in a way
the CLR will pick it up.

[Ironruby-core] byte[] to ruby string

You need to use ?wb? mode to prevent Ruby from transforming eolns.

Subject: Re: [Ironruby-core] byte[] to ruby string

<"This is a test\n"> expected but was
<"This is a test\r\n">.

windows default is to use CRLF for a new line and the CLR inherits that
But for ruby the new line constant is a LF which ruby inherits from *nix based
systems

the dirty workaround is

either specify data0 = "This is a test\r\n"
or
data1.gsub! /\n/, "\r\n"
or
data2.gsub! /\r\n/, "\n"

AFAIK there is no way to override the Environment.NewLine constant in a way the
CLR will pick it up.

Thanks,
CreateBinary made the picture file pass the test.
I''m having some trouble with some plain text and newlines. Any idea why
"test_3" don''t pass?


require ''test/unit''

   fileName = ''flowers.jpg''

   #Ruby

   data1 = File.read(fileName)

   #.Net
   fs = FileStream.new(fileName, FileMode.Open, FileAccess.Read)

In this particular case, I would recommend to use .NET API:
include System::IO
=> Object
stream = FileStream.new("c:\\temp\\a.txt", FileMode.Open,
FileAccess.Read)
=> System.IO.FileStream
"".Append(stream, stream.Length)
=> "hello"
