+
+> This repository is a fork of
+[SimpleMDE, made by Sparksuite](https://github.com/sparksuite/simplemde-markdown-editor/).
+Go to the [dedicated section](#simplemde-fork) for more information.
+
+A drop-in JavaScript text area replacement for writing beautiful and understandable Markdown.
+EasyMDE allows users who may be less experienced with Markdown to use familiar toolbar buttons and shortcuts.
+
+In addition, the syntax is rendered while editing to clearly show the expected result. Headings are larger, emphasized words are italicized, links are underlined, etc.
+
+EasyMDE also features both built-in auto saving and spell checking.
+The editor is entirely customizable, from theming to toolbar buttons and javascript hooks.

+
+## Install EasyMDE
+
+Via [npm](https://www.npmjs.com/package/easymde):
+
+```
+npm install easymde --save
+```
+
+Via the *UNPKG* CDN:
+
+```html
+<link rel="stylesheet" href="https://unpkg.com/easymde/dist/easymde.min.css">
+<script src="https://unpkg.com/easymde/dist/easymde.min.js"></script>
+```
+
+
+## How to use
+
+### Loading the editor
+
+After installing and/or importing the module, you can load EasyMDE onto the first TextArea on the web page:
+
+```html
+<textarea></textarea>
+<script>
+var easyMDE = new EasyMDE();
+</script>
+```
+
+Alternatively you can select a specific TextArea, via Javascript:
+
+```html
+<textarea id="my-text-area"></textarea>
+<script>
+var easyMDE = new EasyMDE({element: document.getElementById('my-text-area')});
+</script>
+```
+
+Or via jQuery:
+
+```html
+<textarea id="my-text-area"></textarea>
+<script>
+var easyMDE = new EasyMDE({element: $('#my-text-area')[0]});
+</script>
+```
+
+
+### Editor functions
+
+Use EasyMDE.value() to get the content of the editor:
+
+```html
+<script>
+easyMDE.value();
+</script>
+```
+
+Use EasyMDE.value(val) to set the content of the editor:
+
+```html
+<script>
+easyMDE.value('New input for **EasyMDE**');
+</script>
+```
+
+
+## Configuration
+
+### Options list
+
+- **autoDownloadFontAwesome**: If set to `true`, force downloads Font Awesome (used for icons). If set to `false`, prevents downloading. Defaults to `undefined`, which will intelligently check whether Font Awesome has already been included, then download accordingly.
+- **autofocus**: If set to `true`, focuses the editor automatically. Defaults to `false`.

+- **previewImagesInEditor**: - EasyMDE will show preview of images, `false` by default, preview for images will appear only for images on separate lines.
+- **insertTexts**: Customize how certain buttons that insert text behave. Takes an array with two elements. The first element will be the text inserted before the cursor or highlight, and the second element will be inserted after. For example, this is the default link value: `["[", "](http://)"]`.
+  - horizontalRule
+  - image
+  - link
+  - table
+- **lineNumbers**: If set to `true`, enables line numbers in the editor.
+- **lineWrapping**: If set to `false`, disable line wrapping. Defaults to `true`.
+- **minHeight**: Sets the minimum height for the composition area, before it starts auto-growing. Should be a string containing a valid CSS value like `"500px"`. Defaults to `"300px"`.
+- **maxHeight**: Sets fixed height for the composition area. `minHeight` option will be ignored. Should be a string containing a valid CSS value like `"500px"`. Defaults to `undefined`.

+  - **mode**: A codemirror mode object.
+  - **combine**: If set to `false`, will *replace* CSS classes returned by the default Markdown mode. Otherwise the classes returned by the custom mode will be combined with the classes returned by the default mode. Defaults to `true`. 
+- **placeholder**: If set, displays a custom placeholder message.
+- **previewClass**: A string or array of strings that will be applied to the preview screen when activated. Defaults to `"editor-preview"`.
+- **previewRender**: Custom function for parsing the plaintext Markdown and returning HTML. Used when user previews.
+- **promptURLs**: If set to `true`, a JS alert window appears asking for the link or image URL. Defaults to `false`.
+- **promptTexts**: Customize the text used to prompt for URLs.
+  - **image**: The text to use when prompting for an image's URL.  Defaults to `URL of the image:`.
+  - **link**: The text to use when prompting for a link's URL. Defaults to `URL for the link:`.
+- **uploadImage**: If set to `true`, enables the image upload functionality, which can be triggered by drag&drop, copy-paste and through the browse-file window (opened when the user click on the *upload-image* icon). Defaults to `false`.
+- **imageMaxSize**: Maximum image size in bytes, checked before upload (note: never trust client, always check image size at server-side). Defaults to `1024*1024*2` (2Mb).
+- **imageAccept**: A comma-separated list of mime-types used to check image type before upload (note: never trust client, always check file types at server-side). Defaults to `image/png, image/jpeg`.
+- **imageUploadFunction**: A custom function for handling the image upload. Using this function will render the options `imageMaxSize`, `imageAccept`, `imageUploadEndpoint` and `imageCSRFToken` ineffective.
+    - The function gets a file and onSuccess and onError callback functions as parameters. `onSuccess(imageUrl: string)` and `onError(errorMessage: string)`
+- **imageUploadEndpoint**: The endpoint where the images data will be sent, via an asynchronous *POST* request. The server is supposed to save this image, and return a json response.
+     - if the request was successfully processed (HTTP 200-OK): `{"data": {"filePath": "<filePath>"}}` where *filePath* is the path of the image (absolute if `imagePathAbsolute` is set to true, relative if otherwise);
+     - otherwise: `{"error": "<errorCode>"}`, where *errorCode* can be `noFileGiven` (HTTP 400), `typeNotAllowed` (HTTP 415), `fileTooLarge` (HTTP 413) or `importError` (see *errorMessages* below). If *errorCode* is not one of the *errorMessages*, it is alerted unchanged to the user. This allows for server side error messages.
+     No default value.
+- **imagePathAbsolute**: If set to `true`, will treat `imageUrl` from `imageUploadFunction` and *filePath* returned from `imageUploadEndpoint` as an absolute rather than relative path, i.e. not prepend `window.location.origin` to it.
+- **imageCSRFToken**: CSRF token to include with AJAX call to upload image. For instance used with Django backend.
+- **imageTexts**: Texts displayed to the user (mainly on the status bar) for the import image feature, where `#image_name#`, `#image_size#` and `#image_max_size#` will replaced by their respective values, that can be used for customization or internationalization:
+    - **sbInit**: Status message displayed initially if `uploadImage` is set to `true`. Defaults to `Attach files by drag and dropping or pasting from clipboard.`.
+    - **sbOnDragEnter**: Status message displayed when the user drags a file to the text area. Defaults to `Drop image to upload it.`.
+    - **sbOnDrop**: Status message displayed when the user drops a file in the text area. Defaults to `Uploading images #images_names#`.
+    - **sbProgress**: Status message displayed to show uploading progress. Defaults to `Uploading #file_name#: #progress#%`.
+    - **sbOnUploaded**: Status message displayed when the image has been uploaded. Defaults to `Uploaded #image_name#`.
+    - **sizeUnits**: A comma-separated list of units used to display messages with human-readable file sizes. Defaults to ` B, KB, MB` (example: `218 KB`). You can use `B,KB,MB` instead if you prefer without whitespaces (`218KB`).
+- **errorMessages**: Errors displayed to the user, using the `errorCallback` option, where `#image_name#`, `#image_size#` and `#image_max_size#` will replaced by their respective values, that can be used for customization or internationalization:
+    - **noFileGiven**: The server did not receive any file from the user. Defaults to `You must select a file.`.
+    - **typeNotAllowed**: The user send a file type which doesn't match the `imageAccept` list, or the server returned this error code. Defaults to `This image type is not allowed.`.
+    - **fileTooLarge**: The size of the image being imported is bigger than the `imageMaxSize`, or if the server returned this error code. Defaults to `Image #image_name# is too big (#image_size#).\nMaximum file size is #image_max_size#.`.
+    - **importError**: An unexpected error occurred when uploading the image. Defaults to `Something went wrong when uploading the image #image_name#.`.
+- **errorCallback**: A callback function used to define how to display an error message. Defaults to `function(errorMessage) {alert(errorMessage);};`.
+- **renderingConfig**: Adjust settings for parsing the Markdown during previewing (not editing).
+  - **codeSyntaxHighlighting**: If set to `true`, will highlight using [highlight.js](https://github.com/isagalaev/highlight.js). Defaults to `false`. To use this feature you must include highlight.js on your page or pass in using the `hljs` option. For example, include the script and the CSS files like:<br>`<script src="https://cdn.jsdelivr.net/highlight.js/latest/highlight.min.js"></script>`<br>`<link rel="stylesheet" href="https://cdn.jsdelivr.net/highlight.js/latest/styles/github.min.css">`
+  - **hljs**: An injectible instance of [highlight.js](https://github.com/isagalaev/highlight.js). If you don't want to rely on the global namespace (`window.hljs`), you can provide an instance here. Defaults to `undefined`.
+  - **markedOptions**: Set the internal Markdown renderer's [options](https://marked.js.org/#/USING_ADVANCED.md#options). Other `renderingConfig` options will take precedence.
+  - **singleLineBreaks**: If set to `false`, disable parsing GFM single line breaks. Defaults to `true`.
+  - **sanitizerFunction**: Custom function for sanitizing the HTML output of markdown renderer.
+- **shortcuts**: Keyboard shortcuts associated with this instance. Defaults to the [array of shortcuts](#keyboard-shortcuts).
+- **showIcons**: An array of icon names to show. Can be used to show specific icons hidden by default without completely customizing the toolbar.
+- **spellChecker**: If set to `false`, disable the spell checker. Defaults to `true`.

+
+
+### Toolbar icons
+
+Below are the built-in toolbar icons (only some of which are enabled by default), which can be reorganized however you like. "Name" is the name of the icon, referenced in the JS. "Action" is either a function or a URL to open. "Class" is the class given to the icon. "Tooltip" is the small tooltip that appears via the `title=""` attribute. Note that shortcut hints are added automatically and reflect the specified action if it has a key bind assigned to it (i.e. with the value of `action` set to `bold` and that of `tooltip` set to `Bold`, the final text the user will see would be "Bold (Ctrl-B)").
+
+Additionally, you can add a separator between any icons by adding `"|"` to the toolbar array.
+
+Name | Action | Tooltip<br>Class
+:--- | :----- | :--------------
+bold | toggleBold | Bold<br>fa fa-bold
+italic | toggleItalic | Italic<br>fa fa-italic
+strikethrough | toggleStrikethrough | Strikethrough<br>fa fa-strikethrough
+heading | toggleHeadingSmaller | Heading<br>fa fa-header
+heading-smaller | toggleHeadingSmaller | Smaller Heading<br>fa fa-header
+heading-bigger | toggleHeadingBigger | Bigger Heading<br>fa fa-lg fa-header
+heading-1 | toggleHeading1 | Big Heading<br>fa fa-header header-1
+heading-2 | toggleHeading2 | Medium Heading<br>fa fa-header header-2

+
+
+### Toolbar customization
+
+Customize the toolbar using the `toolbar` option.
+
+Only the order of existing buttons:
+
+```JavaScript
+var easyMDE = new EasyMDE({
+	toolbar: ["bold", "italic", "heading", "|", "quote"]
+});
+```
+
+All information and/or add your own icons
+
+```Javascript
+var easyMDE = new EasyMDE({
+	toolbar: [{
+			name: "bold",
+			action: EasyMDE.toggleBold,
+			className: "fa fa-bold",
+			title: "Bold",
+		},
+		{
+			name: "custom",
+			action: function customFunction(editor){
+				// Add your own code
+			},
+			className: "fa fa-star",
+			title: "Custom Button",
+		},
+		"|" // Separator
+		// [, ...]
+	]
+});
+```
+
+Put some buttons on dropdown menu
+
+```Javascript
+var easyMDE = new EasyMDE({
+	toolbar: [{
+                name: "heading",
+                action: EasyMDE.toggleHeadingSmaller,
+                className: "fa fa-header",
+                title: "Headers",
+            },
+            "|",
+            {
+                name: "others",
+                className: "fa fa-blind",
+                title: "others buttons",
+                children: [
+                    {
+                        name: "image",
+                        action: EasyMDE.drawImage,
+                        className: "fa fa-picture-o",
+                        title: "Image",
+                    },
+                    {
+                        name: "quote",
+                        action: EasyMDE.toggleBlockquote,
+                        className: "fa fa-percent",
+                        title: "Quote",
+                    },
+                    {
+                        name: "link",
+                        action: EasyMDE.drawLink,
+                        className: "fa fa-link",
+                        title: "Link",
+                    }
+                ]
+            },
+		// [, ...]
+	]
+});
+```
+
+### Keyboard shortcuts
+
+EasyMDE comes with an array of predefined keyboard shortcuts, but they can be altered with a configuration option. The list of default ones is as follows:
+
+Shortcut (Windows / Linux) | Shortcut (macOS) | Action
+:--- | :--- | :---
+*Ctrl-'* | *Cmd-'* | "toggleBlockquote"
+*Ctrl-B* | *Cmd-B* | "toggleBold"
+*Ctrl-E* | *Cmd-E* | "cleanBlock"
+*Ctrl-H* | *Cmd-H* | "toggleHeadingSmaller"
+*Ctrl-I* | *Cmd-I* | "toggleItalic"

+
+```JavaScript
+var editor = new EasyMDE({
+	shortcuts: {
+		"toggleOrderedList": "Ctrl-Alt-K", // alter the shortcut for toggleOrderedList
+		"toggleCodeBlock": null, // unbind Ctrl-Alt-C
+		"drawTable": "Cmd-Alt-T", // bind Cmd-Alt-T to drawTable action, which doesn't come with a default shortcut
+	}
+});
+```
+
+Shortcuts are automatically converted between platforms. If you define a shortcut as "Cmd-B", on PC that shortcut will be changed to "Ctrl-B". Conversely, a shortcut defined as "Ctrl-B" will become "Cmd-B" for Mac users.
+
+The list of actions that can be bound is the same as the list of built-in actions available for [toolbar buttons](#toolbar-icons).
+
+
+## Advanced use
+
+### Event handling
+
+You can catch the following list of events: https://codemirror.net/doc/manual.html#events
+
+```JavaScript
+var easyMDE = new EasyMDE();
+easyMDE.codemirror.on("change", function(){
+	console.log(easyMDE.value());
+});
+```
+
+
+### Removing EasyMDE from text area
+
+You can revert to the initial text area by calling the `toTextArea` method. Note that this clears up the autosave (if enabled) associated with it. The text area will retain any text from the destroyed EasyMDE instance.
+
+```JavaScript
+var easyMDE = new EasyMDE();
+// ...
+easyMDE.toTextArea();
+easyMDE = null;
+```
+
+If you need to remove installed listeners (when editor not needed anymore), call `easyMDE.cleanup()`
+
+
+### Useful methods
+
+The following self-explanatory methods may be of use while developing with EasyMDE.
+
+```js
+var easyMDE = new EasyMDE();
+easyMDE.isPreviewActive(); // returns boolean
+easyMDE.isSideBySideActive(); // returns boolean
+easyMDE.isFullscreenActive(); // returns boolean
+easyMDE.clearAutosavedValue(); // no returned value
+```
+
+
+## How it works
+
+EasyMDE is a continuation of SimpleMDE.
+
+SimpleMDE began as an improvement of [lepture's Editor project](https://github.com/lepture/editor), but has now taken on an identity of its own. It is bundled with [CodeMirror](https://github.com/codemirror/codemirror) and depends on [Font Awesome](http://fontawesome.io).
+
+CodeMirror is the backbone of the project and parses much of the Markdown syntax as it's being written. This allows us to add styles to the Markdown that's being written. Additionally, a toolbar and status bar have been added to the top and bottom, respectively. Previews are rendered by [Marked](https://github.com/chjj/marked) using GFM.
+
+
+## SimpleMDE fork
+
+I originally made this fork to implement FontAwesome 5 compatibility into SimpleMDE. When that was done I submitted a [pull request](https://github.com/sparksuite/simplemde-markdown-editor/pull/666), which has not been accepted yet. This, and the project being inactive since May 2017, triggered me to make more changes and try to put new life into the project.
+
+Changes include:
+* FontAwesome 5 compatibility
+* Guide button works when editor is in preview mode
+* Links are now `https://` by default
+* Small styling changes
+* Support for Node 8 and beyond
+* Lots of refactored code
+* Links in preview will open in a new tab by default
+* Typescript support
+
+My intention is to continue development on this project, improving it and keeping it alive.
+
+
+## Hacking EasyMDE
+
+You may want to edit this library to adapt its behavior to your needs. This can be done in some quick steps:
+
+1. Follow the [prerequisites](./CONTRIBUTING.md#prerequisites) and [installation](./CONTRIBUTING.md#installation) instructions in the contribution guide;
+2. Do your changes;
+3. Run `gulp` command, which will generate files: `dist/easymde.min.css` and `dist/easymde.min.js`;
+4. Copy-paste those files to your code base, and you are done.

 # Blazor Markdown Editor
-This is a Markdown Editor for use in Blazor. It contains a live preview as well as an embeded help guide for users.
+This is a Markdown Editor component for [Blazor WebAssembly](https://www.puresourcecode.com/tag/blazor-webassembly/) and [Blazor Server](https://www.puresourcecode.com/tag/blazor-server/) with .NET6. The component is based on [EasyMDE](https://easy-markdown-editor.tk/) to create the editor and [Markdig](https://github.com/xoofx/markdig) for rendering the Markdown text in HTML. 
+For more documentation and help this component, visit the post I created [here](https://www.puresourcecode.com/dotnet/blazor/markdown-editor-component-for-blazor/).
 
-For the explanation please visit my blog [PureSourceCode](https://www.puresourcecode.com) at this [link](https://www.puresourcecode.com/dotnet/blazor/markdown-editor-with-blazor/).

+@using PSC.Blazor.Components.MarkdownEditor.EventsArgs
 ```
 
-Then, inside of an `EditForm` reference the editor component and bind it.
+Then, in your `index.html` or `host.html` add those lines:
 
 ```
-<EditForm OnValidSubmit="DoSave" Model="model">
-    <MarkdownEditor @bind-Value="model.Comments"/>
-</EditForm>
+<link href="/_content/PSC.Blazor.Components.MarkdownEditor/css/easymde.min.css" rel="stylesheet" />
+
+<script src="/_content/PSC.Blazor.Components.MarkdownEditor/js/easymde.min.js"></script>
+<script src="/_content/PSC.Blazor.Components.MarkdownEditor/js/markdownEditor.js"></script>
+```
+
+Remember that `jQuery` is also required. The component cointains the [EasyMDE](https://easy-markdown-editor.tk/) script version 2.15.0. Obviously, you can add this script in your project but if you use the script in the component, you are sure it works fine and all functionalities are tested.
+
+### Add MarkdownEditor in a page
+
+In a `Razor` page, we can add the component with these lines
+
+```
+<div class="col-md-12">
+    <MarkdownEditor Value="@markdownValue" 
+                    ValueChanged="@OnMarkdownValueChanged"
+                    ValueHTMLChanged="@OnMarkdownValueHTMLChanged" />
+
+    <hr />
+
+    <h3>Result</h3>
+    @((MarkupString)markdownHtml)
+</div>
+
+@code {
+    string markdownValue = "#Markdown Editor\nThis is a test";
+    string markdownHtml;
+
+    protected override void OnInitialized()
+    {
+        markdownHtml = Markdig.Markdown.ToHtml(markdownValue ?? string.Empty);
+        base.OnInitialized();
+    }
+
+    Task OnMarkdownValueChanged(string value)
+    {
+        return Task.CompletedTask;
+    }
+
+    Task OnMarkdownValueHTMLChanged(string value)
+    {
+        markdownHtml = value;
+        return Task.CompletedTask;
+    }
+}
 ```
 
-The editor binds the markdown text, not parsed HTML.
+The result is a nice Markdown Editor like in the following screenshot. This is a screenshot from the demo in this repository.

+## Documentation
+The Markdown Editor for Blazor has a estensive collection of properties to map all the functionalities in the JavaScript version. In this repository, there are 2 projects:
+- **MarkdownEditorDemo** is a Blazor Web Assembly project that contains 2 pages: `Index.razor` where I show how to use the component with the basic functions and `Upload.razor` that shows how to cope with the image upload. To test the upload, the project `MarkdownEditorDemo.Api` must run
+- **MarkdownEditorDemo.Api** this is an ASP.NET Core WebApi (.NET6) how to implement a proper API for uploading images. For more details, I wrote a post about [Uploading image with .NET](https://www.puresourcecode.com/dotnet/net6/upload-download-files-using-httpclient/).

+
+## Upload file
+The Markdown Editor for Blazor can take care of uploading a file and add the relative Markdown code in the editor. For that, the property `UploadImage` has to set to `true`. Also, the upload API must be specified in the property `ImageUploadEndpoint`.
+In some cases, the API requires an authentication. The properties `ImageUploadAuthenticationSchema` and `ImageUploadAuthenticationToken` allow you to pass the correct schema and token to use in the call.
+
+Those values will be added to the `HttpClient` `POST` request in the header. Only if both properties are not null, they will be added to the header.
+
+![markdown-editor-upload-image](https://user-images.githubusercontent.com/9497415/148955032-1d3dc558-f308-4134-b3fd-6d43a0e4e37a.gif)
+
+If you want to understand better how to create the API for the upload, I have created a specific [post](https://www.puresourcecode.com/dotnet/net6/upload-download-files-using-httpclient/) on [PureSourceCode](https://www.puresourcecode.com/).
+
+## Toolbar icons
+
+Below are the built-in toolbar icons (only some of which are enabled by default), which can be reorganized however you like. "Name" is the name of the icon, referenced in the JS. "Action" is either a function or a URL to open. "Class" is the class given to the icon. "Tooltip" is the small tooltip that appears via the `title=""` attribute. Note that shortcut hints are added automatically and reflect the specified action if it has a key bind assigned to it (i.e. with the value of `action` set to `bold` and that of `tooltip` set to `Bold`, the final text the user will see would be "Bold (Ctrl-B)").
+
+Additionally, you can add a separator between any icons by adding `"|"` to the toolbar array.
+
+Name | Action | Tooltip<br>Class
+:--- | :----- | :--------------
+bold | toggleBold | Bold<br>fa fa-bold
+italic | toggleItalic | Italic<br>fa fa-italic
+strikethrough | toggleStrikethrough | Strikethrough<br>fa fa-strikethrough

+guide | [This link](https://www.markdownguide.org/basic-syntax/) | Markdown Guide<br>fa fa-question-circle
+
+## Keyboard shortcuts
+
+EasyMDE comes with an array of predefined keyboard shortcuts, but they can be altered with a configuration option. The list of default ones is as follows:
 
-The toolbar is added by default.  You can disable this by passing `EnableToolbar="false"` into the component.
+Shortcut (Windows / Linux) | Shortcut (macOS) | Action
+:--- | :--- | :---
+*Ctrl-'* | *Cmd-'* | "toggleBlockquote"
