Roslyn analyzers and code fixes support was merged recently into omnisharp-roslyn so this should now be possible.

Until a new preference and an updated stable release of omnisharp-roslyn gets shipped, you'll need to use "omnisharp.path": "latest" in your settings.json and the following in your omnisharp.json:

{
    "RoslynExtensionsOptions": {
        "EnableAnalyzersSupport": true,
        "LocationPaths": [
            "C:\\lib\\roslynator"
        ]
    }
}

I've tested this recently and was able to get both analyzer warnings/errors as well as codefixes.

[josefpihrt]

I think this should work:

string localAppDataPath = Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData);

string path = @"%LOCALAPPDATA%/JosefPihrt/Roslynator/VisualStudioCode";

path = path.Replace("%LOCALAPPDATA%", localAppDataPath);

// "/home/foo/.local/share/JosefPihrt/Roslynator/VisualStudioCode" on Linux with user "foo"
Console.WriteLine(path);

On Windows there will be mixed slashes but I have checked that it's fine.

[domints]

I'll give it a try then, and report the results :)

[divinebovine]

Can we remove the blocked label at this point?

[josefpihrt]

I would like to, but currently it is not possible.

See dotnet/vscode-csharp#43

[snielsson]

So is this still blocked? Or is it now possible to make a VSCode Roslynator Add-in?

[josefpihrt]

I don't think it is possible yet, you can check that the issue mentioned above is still open.

How to enable Roslynator for VS Code

[colin-young]

@josefpihrt I've tried following those instructions, but get:

System.NotSupportedException: An attempt was made to load an assembly from a network location which would have caused the assembly to be sandboxed in previous versions of the .NET Framework. This release of the .NET Framework does not enable CAS policy by default [...]

I fixed that by "unblocking" the assemblies in Windows (7). Now I'm getting:

Expected to use Roslynator.CSharp.CodeFixes, Version=1.6.30.0, Culture=neutral, PublicKeyToken=94dac60bcac1903d in host services but the assembly cannot be loaded due to an exception: Could not load file or assembly 'Roslynator.Workspaces, Version=1.6.30.0, Culture=neutral, PublicKeyToken=8ca34578834dd224' or one of its dependencies. The system cannot find the file specified.. System.Reflection.ReflectionTypeLoadException: Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information.

Any suggestions?

[josefpihrt]

Copying Roslynator.Workspaces.dll to your folder should solve the issue.

I have recently move code dependent on Microsoft.CodeAnalysis.CSharp.Workspaces to new assembly Roslynator.Workspaces but I have not update documentation yet.

[colin-young]

Thanks! One other thing to note is that I needed to restart VS Code to get it to load the DLLs. Simply restarting the Omnisharp extension was not sufficient. Maybe that's only the case when there are problems reading assemblies, and it's not a general problem if you manage to get your configuration right on your first try.

1. Extract DLLs
2. Unblock DLLs in Windows
3. Add/create settings in omnisharp.json
4. Start (or restart) VS Code

[josefpihrt]

I'm glad it works!

I will update documentation accordingly.

[domints]

Are these DLLs .NET Standard? I mean, would that work with VS Code on Mac?

[josefpihrt]

Roslynator targets .NET Standard 1.3

[divinebovine]

Looks like the new preference is available in the latest omnisharp. This will remove the need for the "EnableAnalyzersSupport" setting in your omnisharp.json.

[josefpihrt]

Does anybody know how to pack roslyn libraries as VS Code extension?

[sbmw]

This is fantastic news!

One thing. Currently user-level rules can be set by creating files at %LOCALAPPDATA%\JosefPihrt\Roslynator. This isn't possible for people running VS Code on non-Windows environments.

I think you could just update roslyn/common/roslynator.config within the extension to include a couple of extra imports like:

<Include Path="~/roslynator.config" />
...
<RuleSet Path="~/roslynator.ruleset" />

and users would be able to create a config and ruleset in their home directory?

[josefpihrt]

I should not be necessary to add more paths to roslynator config. It should be sufficient to replace %LOCALAPPDATA% with value of returned by Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData).

I do not have OSX or Linux installed on my machine but I found this page that lists all values:

ENM: System.Environment.SpecialFolder.LocalApplicationData
WIN: C:\Users\foo\AppData\Local
LIN: /home/foo/.local/share
OSX: /Users/foo/.local/share

[josefpihrt]

Is anybody able to test that following code snippet will work on non-Windows environment?

using System;
using System.IO;
using System.Diagnostics;

string localAppDataPath = Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData);

string path = @"%LOCALAPPDATA%\JosefPihrt\Roslynator\VisualStudioCode";

path = path.Replace("%LOCALAPPDATA%", localAppDataPath);

// normalize directory separator
path = Path.GetFullPath(path);

// LINUX
Debug.Assert(path == "/home/foo/.local/share/JosefPihrt/Roslynator/VisualStudioCode");

// OSX
Debug.Assert(path == "/Users/foo/.local/share/JosefPihrt/Roslynator/VisualStudioCode");

Thanks.

[domints]

When I replaced /home/foo/ with my current user directory on Linux Assert failed because of wrong slashes.
Otherwise path looks fine (I added Console.WriteLine) :)

My Linux is some kind of Debian (9 I think) and my dotnet version is 2.2.300

[sbmw]

@josefpihrt yes, your way is definitely better than adding more paths.

As domints says, the directory normalizing isn't working.

You could do something like

if (Environment.OSVersion.Platform != PlatformID.Win32NT)
{
    path = path.Replace(@"\", "/");
}

Or else I think just using forward slashes as directory separators will work across all platforms?

[divinebovine]

You could use Path.PathSeparator for platform aware separators

[domints]

@sbmw that's not the good way :) I believe System.IO.Path has field specifying the correct path delimiter. It's DirectorySeparatorChar. But as AltDirectorySeparatorChar specifies on Windows, Windows also understands / slash, so that might be a way to go.

I think GetFullPath didn't fix slashes on Linux, because neither DirectorySeparatorChar nor AltDirectorySeparatorChar specify \ as proper separator on Linux.

@divinebovine Path.PathSeparator is meant to separate multiple paths, not directories in single path. It resolves to ; on Windows and : on Linux.

[ADIX7]

There is Path.Combine to combine path parts.

[divinebovine]

@domints you're right, my mistake

[domints]

@ADIX7

There is Path.Combine to combine path parts.

yet it doesn't fix anything :)

[ADIX7]

Realy, I haven't read back enough posts...
Joining to @domints: doesn't / work on windows? Or you can expect / and replace it with Path.DirectorySeparatorChar.

According to this / should work on windows too:
