kandi X-RAY | binaryparser Summary
BinaryParser is a node.js module which facilitates parsing of binary data received from the network or from a local file. BinaryParser lets you define the data format using javascript object notation and allows for parsing of complex binary streams. Callbacks are called whenever a binary field has been received and the data format can be changed on-the-fly. Include the binary parser.

QUESTION
Goal
I have been trying to write a simple step-by-step reduction algorithm, which would simplify given logic equations and show steps of simplification. To start with, I decided to implement a reduction in parentheses. To retrieve all nesting parentheses I use ANTLR.
Materials
I wrote a simple grammar for logic expressions trying to use a left-recursive feature of ANTLRv4:
Binary.g4
...ANSWER
Answered 2020-Jul-04 at 20:59I took your grammar and listener code, and wrote a program to run it. I also printed out the token stream and parse tree for your input. It's producing exactly what one would expect. However, what I got in the output from the println() in the listener output, shown below, differs from what you provided in your question. The output from my program is the same result for Java and C#, token indices from 0 to 19 (the EOF token). I can only think that maybe you are using an older tool and runtime. Make sure you are using 4.8 of the Antlr Tool and runtime.

I am migrating a library from .net framework 4.7 to .net core 2.2 and found an issue with deep object cloning that I narrowed down to a short reproducible code snippet below.
Try this yourself:
- .net framework 4.7.2 (Pass)
- .net core 2.2 (Fail)
ANSWER
Answered 2019-Aug-26 at 17:02Indeed it seems like a bug. Thanks for raising the issue.
However, from your comments it seems like there is a simple workaround. Instead of serializing the TimeZoneInfo
, change your object to serialize just the ID. You can put a property with get/set accessors around it for convenience if you like.
For example, instead of:

I am trying to implement a binary parser combinator library using Span. I am not sure if this is actually a good idea I just want to learn more about both.
I have already written a small binary parser a while ago using parser combinators which works perfectly.
The code looks like this:

QUESTION
I have ported a number of class libraries from .NET Framework 4.5 to .NET Standard 2.0. Using these libraries from a .NET Framework 4.8 console application works fine. However referencing the libraries from a .NET Core 2.2 console app, results in the following exception:
...ANSWER
Answered 2019-May-18 at 02:43Answer from Microsoft: “In .NET Core fewer types are binary serializable than in .NET Framework. This is by design because serialization based on BinaryFormatter has historically been fragile and prone to security problems. SyncHashtable is not currently serializable. However we should probably make it so. Meantime you need to avoid serializing it. This may mean using Hashtable and manually locking instead of using SyncHashtable. Or possibly (advanced) using the extension mechanisms of BinaryFormatter to work around the problem.”

QUESTION
In Eclipse CDT at DefaultBinaryFileEditor class, in the method getStorage there is a comment that tells the line objdump.getOutput(limitBytes) is a UI blocking call...
How can I make it run in background without UI Blocking to process longer files than it is stated with parameter int limitBytes = 6*1024*1024;
I can access org.eclipse.cdt.utils.Objdump class' getOutput method via plugin.xml extension point "org.eclipse.cdt.core.BinaryParser"...
I tried to replace the class that is used in extension point "org.eclipse.ui.editors" in editor tag with id "org.eclipse.cdt.ui.binaryEditor" via my plugin.xml, but this did not worked.
...ANSWER
Answered 2018-Oct-05 at 13:56I put a boolean flag to outer class and in inner class BinaryFileEditorInput in method getStorage I put a Job and before this job works I created an empty fStorage = new FileStorage. I return this empty fstorage. So first the editor gets blank. Then when the objdump.getOutput(limitBytes) method returns in job, I set the fStorage to the returned output. I simply call the outer class'es refresh method. I put a reference of created outer class to inner static class in outerclasses constructor. This way I can access the refresh method. Also I moved fStorage varible to outerclass because refresh method triggers creating a new inner class so it overrides the valuable fStorage variable.
Finally If you want to update the opened elf file editor when you build the project again, assign the boolean variable and fStorage to first values in method resourceChanged before calling refresh method.
