In yaml-cpp, how do you change the old API snippet:
YAML::Node doc;
while(parser.GetNextDocument(doc)) {
// ...
}
into the new API?
You can use
std::vector<YAML::Node> docs = YAML::LoadAll("--- foo\n--- bar\n");
(or the analogous LoadAllFromFile) to parse a sequence of documents.

I am using this google cloud text to speech like they write in their website. https://codelabs.developers.google.com/codelabs/cloud-text-speech-csharp/#6 )
But there are no details about how to take output Wavenet voices (Ssml) . This coding output is normal voices.
My question is, with this code, how I can take to human accent (Wavenet or Ssml voieces)?
using Google.Cloud.TextToSpeech.V1;
using System;
using System.IO;
namespace TextToSpeechApiDemo
{
class Program
{
static void Main(string[] args)
{
var client = TextToSpeechClient.Create();
// The input to be synthesized, can be provided as text or SSML.
var input = new SynthesisInput
{
**Text = "This is a demonstration of the Google Cloud Text-to-Speech API"
};
// Build the voice request.
var voiceSelection = new VoiceSelectionParams
{
LanguageCode = "en-US",
SsmlGender = SsmlVoiceGender.Female**
};
// Specify the type of audio file.
var audioConfig = new AudioConfig
{
AudioEncoding = AudioEncoding.Mp3
};
// Perform the text-to-speech request.
var response = client.SynthesizeSpeech(input, voiceSelection, audioConfig);
// Write the response to the output file.
using (var output = File.Create("output.mp3"))
{
response.AudioContent.WriteTo(output);
}
Console.WriteLine("Audio content written to file \"output.mp3\"");
}
}
}
Here you can check the languages and voices supported in text-to-speech API. As described in this tutorial the speech is characterized by three parameters: the language_code, the name and the ssml_gender.
You can employ the following Python code to translate the text "Hello my name is John. How are you?" into English with the accent en-GB-Standard-A
def synthesize_text(text):
"""Synthesizes speech from the input string of text."""
from google.cloud import texttospeech
client = texttospeech.TextToSpeechClient()
input_text = texttospeech.types.SynthesisInput(text=text)
# Note: the voice can also be specified by name.
# Names of voices can be retrieved with client.list_voices().
voice = texttospeech.types.VoiceSelectionParams(
language_code='en-GB',
name='en-GB-Standard-A',
ssml_gender=texttospeech.enums.SsmlVoiceGender.FEMALE)
audio_config = texttospeech.types.AudioConfig(
audio_encoding=texttospeech.enums.AudioEncoding.MP3)
response = client.synthesize_speech(input_text, voice, audio_config)
# The response's audio_content is binary.
with open('output.mp3', 'wb') as out:
out.write(response.audio_content)
print('Audio content written to file "output.mp3"')
text="Hello my name is John. How are you?"
synthesize_text(text)
I am not familiar with C# language but judging by the C# and java documentations you should be able to define the name parameter as well to tune the speech.
I am using Google diff-match-patch JAVA plugin to create patch between two JSON strings and storing the patch to database.
diff_match_patch dmp = new diff_match_patch();
LinkedList<Patch> diffs = dmp.patch_make(latestString, originalString);
String patch = dmp.patch_toText(diffs); // Store patch to DB
Now is there any way to use this patch to re-create the originalString by passing the latestString?
I google about this and found this very old comment # Google diff-match-patch Wiki saying,
Unpatching can be done by just looping through the diff, swapping
DIFF_INSERT with DIFF_DELETE, then applying the patch.
But i did not find any useful code that demonstrates this. How could i achieve this with my existing code ? Any pointers or code reference would be appreciated.
Edit:
The problem i am facing is, in the front-end i am showing a revisions module that shows all the transactions of a particular fragment (take for example an employee details), like which user has updated what details etc. Now i am recreating the fragment JSON by reverse applying each patch to get the current transaction data and show it as a table (using http://marianoguerra.github.io/json.human.js/). But some JSON data are not valid JSON and I am getting JSON.parse error.
I was looking to do something similar (in C#) and what is working for me with a relatively simple object is the patch_apply method. This use case seems somewhat missing from the documentation, so I'm answering here. Code is C# but the API is cross language:
static void Main(string[] args)
{
var dmp = new diff_match_patch();
string v1 = "My Json Object;
string v2 = "My Mutated Json Object"
var v2ToV1Patch = dmp.patch_make(v2, v1);
var v2ToV1PatchText = dmp.patch_toText(v2ToV1Patch); // Persist text to db
string v3 = "Latest version of JSON object;
var v3ToV2Patch = dmp.patch_make(v3, v2);
var v3ToV2PatchTxt = dmp.patch_toText(v3ToV2Patch); // Persist text to db
// Time to re-hydrate the objects
var altV3ToV2Patch = dmp.patch_fromText(v3ToV2PatchTxt);
var altV2 = dmp.patch_apply(altV3ToV2Patch, v3)[0].ToString(); // .get(0) in Java I think
var altV2ToV1Patch = dmp.patch_fromText(v2ToV1PatchText);
var altV1 = dmp.patch_apply(altV2ToV1Patch, altV2)[0].ToString();
}
I am attempting to retrofit this as an audit log, where previously the entire JSON object was saved. As the audited objects have become more complex the storage requirements have increased dramatically. I haven't yet applied this to the complex large objects, but it is possible to check if the patch was successful by checking the second object in the array returned by the patch_apply method. This is an array of boolean values, all of which should be true if the patch worked correctly. You could write some code to check this, which would help check if the object can be successfully re-hydrated from the JSON rather than just getting a parsing error. My prototype C# method looks like this:
private static bool ValidatePatch(object[] patchResult, out string patchedString)
{
patchedString = patchResult[0] as string;
var successArray = patchResult[1] as bool[];
foreach (var b in successArray)
{
if (!b)
return false;
}
return true;
}
Looking for sample for building ANTLR4 grammar based Code Editor with intellisense. SharpDevelop provides all Code Editor features, however if we need to provide the intellisense and Code Completion details, then we need to write own parser.
Need sample where ANTLR4, SharpDevelop is used for building the Code Editor for custom language.
Thanks.
I could get the expected Tokens from ANTLR4 using GetExpectedTokensWithinRule API in the Listener and converting them to tokens.
pseudo code looks like this
public class MyGrammarListener : MyGrammarBaseListener
{
public MyGrammarListener(MyGrammarParser parser)
{
this.Parser = parser;
}
public override void EnterXXXXX(XXXXX_Context context)
{
IntervalSet set = Parser.GetExpectedTokensWithinCurrentRule();
base.EnterXXXXX(context);
foreach (int token in set.ToIntegerList())
{
// Returns the expected tokens.
string data = Parser.Vocabulary.GetLiteralName(token);
}
}
}
I have used Jide CodeEditor with antlr4, it seems to be working OK but took some time to get it together. I generate the errors and keywords for highlighting from the parser. I use listeners for parsing etc. and a visitor for executing the language. Not familiar with SharpDevelop
all examples show how to read an xml from an local file. But how do I read a xml from a url or a stream and process it further?
Example: http://www.oreillynet.com/xml/blog/2006/03/hello_saxon_on_net_an_aspnet_i.html
thanks in advance
Look for XsltExamples.cs in the saxon-resources download available on both Sourceforge and www.saxonica.com. The very first example seems to do what you are asking for.
public static void ExampleSimple1(String sourceUri, String xsltUri) {
// Create a Processor instance.
Processor processor = new Processor();
// Load the source document
XdmNode input = processor.NewDocumentBuilder().Build(new Uri(sourceUri));
// Create a transformer for the stylesheet.
XsltTransformer transformer = processor.NewXsltCompiler().Compile(new Uri(xsltUri)).Load();
// Set the root node of the source document to be the initial context node
transformer.InitialContextNode = input;
// Create a serializer
Serializer serializer = new Serializer();
serializer.SetOutputWriter(Console.Out);
// Transform the source XML to System.out.
transformer.Run(serializer);
}
Are you using an XmlDocument object for reading the XML? If so, you'll want XMLDocument.Load() method, which can take a file path or URL, TextReader or Stream as input.
Likewise, XDocument.Load()(msdn.microsoft.com/en-us/library/system.xml.linq.xdocument.load(v=vs.110).aspx) has a similar set of overloads.
While using the Rss20FeedFormatter class in a WCF project, I was trying to wrap the content of my description elements with a <![CDATA[ ]]> section. I found that no matter what I did, the HTML content of the description elements was always encoded and the CDATA section was never added. After peering into the source code of Rss20FeedFormatter, I found that when building the Summary node, it basically creates a new TextSyndicationContent instance which wipes out whatever settings were previously specified (I think).
My Code
public class CDataSyndicationContent : TextSyndicationContent
{
public CDataSyndicationContent(TextSyndicationContent content)
: base(content)
{
}
protected override void WriteContentsTo(System.Xml.XmlWriter writer)
{
writer.WriteCData(Text);
}
}
... (The following code should wrap the Summary with a CDATA section)
SyndicationItem item = new SyndicationItem();
item.Title = new TextSyndicationContent(name);
item.Summary = new CDataSyndicationContent(
new TextSyndicationContent(
"<div>This is a test</div>",
TextSyndicationContentKind.Html));
Rss20FeedFormatter Code
(AFAIK, the above code does not work because of this logic)
...
else if (reader.IsStartElement("description", ""))
result.Summary = new TextSyndicationContent(reader.ReadElementString());
...
As a workaround, I've resorted to using the RSS20FeedFormatter to build the RSS, and then patch the RSS manually. For example:
StringBuilder buffer = new StringBuilder();
XmlTextWriter writer = new XmlTextWriter(new StringWriter(buffer));
feedFormatter.WriteTo(writer ); // feedFormatter = RSS20FeedFormatter
PostProcessOutputBuffer(buffer);
WebOperationContext.Current.OutgoingResponse.ContentType =
"application/xml; charset=utf-8";
return new MemoryStream(Encoding.UTF8.GetBytes(buffer.ToString()));
...
public void PostProcessOutputBuffer(StringBuilder buffer)
{
var xmlDoc = XDocument.Parse(buffer.ToString());
foreach (var element in xmlDoc.Descendants("channel").First()
.Descendants("item")
.Descendants("description"))
{
VerifyCdataHtmlEncoding(buffer, element);
}
foreach (var element in xmlDoc.Descendants("channel").First()
.Descendants("description"))
{
VerifyCdataHtmlEncoding(buffer, element);
}
buffer.Replace(" xmlns:a10=\"http://www.w3.org/2005/Atom\"",
" xmlns:atom=\"http://www.w3.org/2005/Atom\"");
buffer.Replace("a10:", "atom:");
}
private static void VerifyCdataHtmlEncoding(StringBuilder buffer,
XElement element)
{
if (!element.Value.Contains("<") || !element.Value.Contains(">"))
{
return;
}
var cdataValue = string.Format("<{0}><![CDATA[{1}]]></{2}>",
element.Name,
element.Value,
element.Name);
buffer.Replace(element.ToString(), cdataValue);
}
The idea for this workaround came from the following location, I just adapted it to work with WCF instead of MVC. http://localhost:8732/Design_Time_Addresses/SyndicationServiceLibrary1/Feed1/
I'm just wondering if this is simply a bug in Rss20FeedFormatter or is it by design? Also, if anyone has a better solution, I'd love to hear it!
Well #Page Brooks, I see this more as a solution then as a question :). Thanks!!! And to answer your question ( ;) ), yes, I definitely think this is a bug in the Rss20FeedFormatter (though I did not chase it as far), because had encountered precisely the same issue that you described.
You have a 'localhost:8732' referral in your post, but it wasn't available on my localhost ;). I think you meant to credit the 'PostProcessOutputBuffer' workaround to this post:
http://damieng.com/blog/2010/04/26/creating-rss-feeds-in-asp-net-mvc
Or actually it is not in this post, but in a comment to it by David Whitney, which he later put in a seperate gist here:
https://gist.github.com/davidwhitney/1027181
Thank you for providing the adaption of this workaround more to my needs, because I had found the workaround too, but was still struggling to do the adaptation from MVC. Now I only needed to tweak your solution to put the RSS feed to the current Http request in the .ashx handler that I was using it in.
Basically I'm guessing that the fix you mentioned using the CDataSyndicationContent, is from feb 2011, assuming you got it from this post (at least I did):
SyndicationFeed: Content as CDATA?
This fix stopped working in some newer ASP.NET version or something, due to the code of the Rss20FeedFormatter changing to what you put in your post. This code change might as well have been an improvement for other stuff that IS in the MVC framework, but for those using the CDataSyndicationContent fix it definitely causes a bug!
string stylesheet = #"<xsl:stylesheet version=""1.0"" xmlns:xsl=""http://www.w3.org/1999/XSL/Transform""><xsl:output cdata-section-elements=""description"" method=""xml"" indent=""yes""/></xsl:stylesheet>";
XmlReader reader = XmlReader.Create(new StringReader(stylesheet));
XslCompiledTransform t = new XslCompiledTransform(true);
t.Load(reader);
using (MemoryStream ms = new MemoryStream())
{
XmlWriter writer = XmlWriter.Create(ms, t.OutputSettings);
rssFeed.WriteTo(writer); // rssFeed is Rss20FeedFormatter
writer.Flush();
ms.Position = 0;
string niko = Encoding.UTF8.GetString(ms.ToArray());
}
I'm sure someone pointed this out already but this a stupid workaround I used.
t.OutputSettings is of type XmlWriterSettings with cdataSections being populated with a single XmlQualifiedName "description".
Hope it helps someone else.
I found the code for Cdata elsewhere
public class CDataSyndicationContent : TextSyndicationContent
{
public CDataSyndicationContent(TextSyndicationContent content)
: base(content)
{
}
protected override void WriteContentsTo(System.Xml.XmlWriter writer)
{
writer.WriteCData(Text);
}
}
Code to call it something along the lines:
item.Content = new Helpers.CDataSyndicationContent(new TextSyndicationContent("<span>TEST2</span>", TextSyndicationContentKind.Html));
However the "WriteContentsTo" function wasn't being called.
Instead of Rss20FeedFormatter I tried Atom10FeedFormatter - and it worked!
Obviously this gives Atom feed rather than traditional RSS - but worth mentioning.
Output code is:
//var formatter = new Rss20FeedFormatter(feed);
Atom10FeedFormatter formatter = new Atom10FeedFormatter(feed);
using (var writer = XmlWriter.Create(response.Output, new XmlWriterSettings { Indent = true }))
{
formatter.WriteTo(writer);
}
