MirrorSharp is a code editor <textarea> built on Roslyn and CodeMirror.

You'll need the following:

• MirrorSharp.Owin on the server (.NET Core is planned, but not supported yet)
• mirrorsharp.js — client library that provides the user interface

NuGet: Install-Package MirrorSharp.Owin -Pre
Once installed, call app.UseMirrorSharp() in your OWIN startup.

NPM: npm install mirrorsharp --save

If you are using LESS, CSS references can be done automatically by including mirrorsharp/mirrorsharp.less.
Otherwise, make sure to include the following:

1. codemirror/lib/codemirror.css
2. codemirror/addon/lint/lint.css
3. codemirror/addon/hint/show-hint.css
4. codemirror-addon-infotip/dist/infotip.css
5. codemirror-addon-lint-fix/dist/lint-fix.css
6. mirrorsharp/mirrorsharp.css

JS can be done automatically since mirrorsharp has proper requires. Otherwise:

1. codemirror/lib/codemirror.js
2. codemirror/mode/clike/clike.js
3. codemirror/addon/lint/lint.js
4. codemirror/addon/hint/show-hint.js
5. codemirror-addon-infotip/dist/infotip.js
6. codemirror-addon-lint-fix/dist/lint-fix.js
7. mirrorsharp/mirrorsharp.js

Once referenced, you can do the following:

mirrorsharp(textarea, { serviceUrl: 'wss://your_app_root/mirrorsharp' })

If you're not using HTTPS, you'll likely need ws:// instead of wss://.

Note that textarea is an actual textarea element, and not a CSS selector or jQuery object.

TODO. In general the idea is that "it just works", however customization is a goal and some options are already available.

You can check out the demos if you clone the repository locally.
After cloning, run .\mirrorsharp build to build and prepare everything.

TODO, but see MirrorSharp.Testing on NuGet.
