sharps | Modular grid powered by Lost and BEM | Grid library

I have an application that allows users to write c-sharp code that gets saved as a class library for being called later.

A new requirement has been established that some namespaces (and the methods they contain and any variables or methods with their return types) are not allowed anymore. So I need to analyze the code and alert the user to any forbidden namespaces in their code so they can remove them.

Using Roslyn, I can access the InvocationExpressionSyntax nodes for the method calls. From that I then get the symbol info by calling var mySymbol = mySemanticModel.GetSymbolInfo(myInvocationExpressionSyntaxNode).Symbol.

Then calling mySymbol.ContainingType.ToDisplayString() returns the namespace type of the call.

However, it seems not all called methods have symbol information in Roslyn. For example, System.Math.Sqrt() has symbol information, so from that I can get the containing namespace of System.Math. On the other hand System.Net.WebRequest.Create() or System.Diagnostics.Process.Start() do not. How do I get System.Net.WebRequest or System.Dignostics.Process from those nodes? I can clearly see them using QuickWatch.

For example, the System.Diagnostics.Process.Start() node itself shows the following value in QuickWatch: InvocationExpressionSyntax InvocationExpression System.Diagnostics.Process.Start("CMD.exe","")

And the node's expression has this value: MemberAccessExpressionSyntax SimpleMemberAccessExpression System.Diagnostics.Process.Start

So obviously the namespace is there in the value itself. But the Symbol from the SymbolInfo and the Type from TypeInfo are both null.

Edit

In regards to my compilation, the C# Roslyn tools are set up as follows (we are supposed to support VB as well, hence the properties are interfaced):

As a part of SHA-256 hashing algorithm, there's a function that is often being referred as σ1, or sigma0 for convenience. Basically, it takes X as input, where X is 32-bit unsigned value. Then converts it like this:

So I've seen a number of different ways to do this but none that fit how I'm set up. I would like to add placeholder for the text fields in my form ('user', 'title', 'comment')

forms.py

Sorry if the question itself is confusing. I have a model with two lists that are used as dropdown lists for the user to choose from. Everything works fine except when viewing the data it will just show the key when I want it to show the value.

In short, I am using gatsby-plugin-remark and gatsby-transformer-remark to optimize images placed within frontmatter of md files.

Say my markdown file has

currently I am trying to switch from the embedded use of svn to the sharp svn plugin. The program I am working with did work and do what it should do but since i try to do it with sharp svn its crashing at the update step.

The code did run with the svn command:

svn update localRepoPath

I did already found a lot of code but none of this is working for me, here is the code at the moment:

I am new to the SharpApp By ServiceStack and Dotnet Core. I were trying to Pascel WebApp Template the following article to setup the basic SharpApp. In the SharpApp article, they have to setup/install dotnet tools.

I tried these:

I am trying to to create a quick tool for seeing notes in a musical scale. The user enters a scale name and the program spits out the notes. For example, you enter C, then the output shows “C, D, E, F, G, A, B.” I have only the first two notes set up, without flats or sharps. To keep everything neat, I want to build the scale from a single array, only I don’t know how to loop back through the array. If the user enters G, it displays an error message that the range is exceeded. How can I make it so that after the user enters G, it prints G “G, B?”

Since my last post I've made some headway in my Wallpaper-- fixing a lot of my prior issues

Today though I'd like some direction if anyone has it:

The last widget that I'm working on is an Audio Visualizer. My pursuit of desiring uniqueness isn't without its issues however (... can you really be a programmer without this attribute?). Here's the reference that I am modeling, a visualizer I made a few weeks ago in After Effects. https://youtu.be/cHweVjmBmP4

In the "limitations" of Javascript and Wallpaper Engine, is there anyway that I can replicate these sharps bends and curves in my output? I at first believed that a variable employing the arcTo() method would help out here.. but it's unclear to me what coordinates would be used for my tangents. And what formula would help explain the affected data.

Here's the code as it stands. Thanks to Michael Fedora for writing such an accessible code. I have learned so much about algorithms from reading and even more by testing things on my own. I'll keep trying to figure this out but any help is endlessly appreciated!
