+# Excalidraw Automate How To
+
+Excalidraw Automate allows you to create Excalidraw drawings using the [Templater](https://github.com/SilentVoid13/Templater) plugin.
+
+With a little work, using Excalidraw Automate you can generate simple mindmaps, fill out SVG forms, create customized charts, etc. based on documents in your vault.
+
+You can access Excalidraw Automate via the ExcalidrawAutomate object. I recommend starting your Automate scripts with the following code.
+
+*Use CTRL+Shift+V to paste code into Obsidian!*
+```javascript
+const ea = ExcalidrawAutomate;
+ea.reset();
+```
+
+The first line creates a practical constant so you can avoid writing ExcalidrawAutomate 100x times.
+
+The second line resets ExcalidrawAutomate to defaults. This is important as you will not know which template you executed before, thus you won't know what state you left Excalidraw in.
+
+## Basic logic of using Excalidraw Automate
+1. Set the styling of the elements you want to draw
+2. Add elements. As you add elements, each new element is added one layer above the previous, thus in case of overlapping objects the later one will be on the top of the prior one.
+3. Call `await ea.create();` to instantiate the drawing
+
+You can change styling between adding different elements. My logic for separating element styling and creation is based on the assumption that you will probably set a stroke color, stroke style, stroke roughness, etc. and draw most of your elements using this. There would be no point in setting all these parameters each time you add an element.
+
+### Before we dive deeper, here are two a simple example scripts
+#### Create a new drawing with custom name, in a custom folder, using a template
+This simple script gives you significant additional flexibility over Excalidraw Plugin settings to name your drawings, place them into folders, and to apply templates.
+
+*Use CTRL+Shift+V to paste code into Obsidian!*
+```javascript
+<%*
+  const ea = ExcalidrawAutomate;
+  ea.reset();
+  await ea.create({
+    filename    : tp.date.now("HH.mm"), 
+    foldername  : tp.date.now("YYYY-MM-DD"),
+    templatePath: "Excalidraw/Template1.excalidraw",
+    onNewPane   : false
+  });
+%>
+```
+
+#### Create a simple drawing
+*Use CTRL+Shift+V to paste code into Obsidian!*
+```javascript
+<%*
+  const ea = ExcalidrawAutomate;
+  ea.reset();
+  ea.addRect(-150,-50,450,300);
+  ea.addText(-100,70,"Left to right");
+  ea.addArrow([[-100,100],[100,100]]);
+
+  ea.style.strokeColor = "red";
+  ea.addText(100,-30,"top to bottom",{width:200,textAligh:"center"});
+  ea.addArrow([[200,0],[200,200]]);
+  await ea.create();
+%>
+```
+The script will generate the following drawing:

+
+## Attributes and functions at a glance
+Here's the interface implemented by ExcalidrawAutomate:

+
+## Element Style
+As you will notice, some styles have setter functions. This is to help you navigate the allowed values for the property. You do not need to use the setter function however, you can use set the value directly as well.
+
+### strokeColor
+String. The color of the line. [CSS Legal Color Values](https://www.w3schools.com/cssref/css_colors_legal.asp)
+
+Allowed values are [HTML color names](https://www.w3schools.com/colors/colors_names.asp), hexadecimal RGB strings, or  e.g. `#FF0000` for red.
+
+### backgroundColor

+
+### angle
+Number. Rotation in radian. 90° == `Math.PI/2`.
+
+### fillStyle, setFillStyle()
+```typescript
+type FillStyle = "hachure" | "cross-hatch" | "solid";
+setFillStyle (val:number);
+```
+fillStyle is a string.
+
+`setFillStyle()` accepts a number:
+- 0: "hachure"
+- 1: "cross-hatch"
+- any other number: "solid"
+
+### strokeWidth
+Number, sets the width of the stroke.
+
+### strokeStyle, setStrokeStyle()

+
+### strokeSharpness, setStrokeSharpness()
+```typescript
+type StrokeSharpness = "round" | "sharp";
+setStrokeSharpness(val:nmuber);
+```
+strokeSharpness is a string.
+
+"round" lines are curvey, "sharp" lines break at the turning point.
+
+`setStrokeSharpness()` accepts a number:
+- 0: "round"
+- any other number: "sharp"
+
+### fontFamily, setFontFamily()
+Number. Valid values are 1,2 and 3.
+
+`setFontFamily()` will also accept a number and return the name of the font.
+- 1: "Virgil, Segoe UI Emoji"
+- 2: "Helvetica, Segoe UI Emoji"
+- 3: "Cascadia, Segoe UI Emoji"
+
+### fontSize
+Number. Default value is 20 px

+
+This is relevant when setting a fix width using the `addText()` function.
+
+### verticalAlign
+String. Alignment of the text vertically. Valid values are "top" and "middle".
+
+This is relevant when setting a fix height using the `addText()` function.
+
+### startArrowHead, endArrowHead

+
+## Adding objects
+These functions will add objects to your drawing. The canvas is infinite, and it accepts negative and positive X and Y values. X values increase left to right, Y values increase top to bottom.
+
+![coordinates](https://user-images.githubusercontent.com/14358394/116825632-6569b980-ab90-11eb-827b-ada598e91e46.png)
+
+### addRect(), addDiamond(), addEllipse()
+```typescript
+addRect(topX:number, topY:number, width:number, height:number):string
+addDiamond(topX:number, topY:number, width:number, height:number):string
+addEllipse(topX:number, topY:number, width:number, height:number):string
+```
+Returns the `id` of the object. The `id` is required when connecting objects with lines. See later.
+
+### addText
+```typescript
+addText(topX:number, topY:number, text:string, formatting?:{width:number, height:number,textAlign: string, verticalAlign:string, box: boolean, boxPadding: number}):string
+```
+
+Adds text to the drawing. 
+
+Formatting parameters are optional:
+- If `width` and `height` are not specified, the function will calculate the width and height based on the fontFamily, the fontSize and the text provided.
+- In case you want to position a text in the center compared to other elements on the drawing, you can provide a fixed height and width, and you can also specify `textAlign` and `verticalAlign` as described above. e.g.: `{width:500, textAlign:"center"}`
+- If you want to add a box around the text, set `{box:true}`
+
+Returns the `id` of the object. The `id` is required when connecting objects with lines. See later. If `{box:true}` then returns the id of the enclosing box.
+
+### addLine()
+```typescript
+addLine(points: [[x:number,y:number]]):void
+```
+Adds a line following the points provided. Must include at least two points `points.length >= 2`. If more than 2 points are provided the interim points will be added as breakpoints. The line will break with angles if `strokeSharpness` is set to "sharp" and will be curvey if it is set to "round".
+
+### addArrow()
+```typescript
+addArrow(points: [[x:number,y:number]],formatting?:{startArrowHead:string,endArrowHead:string,startObjectId:string,endObjectId:string}):void
+```
+
+Adds an arrow following the points provided. Must include at least two points `points.length >= 2`. If more than 2 points are provided the interim points will be added as breakpoints. The line will break with angles if element `style.strokeSharpness` is set to "sharp" and will be curvey if it is set to "round".
+
+`startArrowHead` and `endArrowHead` specify the type of arrow head to use, as described above. Valid values are "none", "arrow", "dot", and "bar". e.g. `{startArrowHead: "dot", endArrowHead: "arrow"}`
+
+`startObjectId` and `endObjectId` are the object id's of connected objects. I recommend using `connectObjects` instead calling addArrow() for the purpose of connecting objects.
+
+### connectObjects()
+```typescript
+declare type ConnectionPoint = "top"|"bottom"|"left"|"right";
+connectObjects(objectA: string, connectionA: ConnectionPoint, objectB: string, connectionB: ConnectionPoint, formatting?:{numberOfPoints: number,startArrowHead:string,endArrowHead:string, padding: number}):void
+```
+Connects two objects with an arrow.
+
+`objectA` and `objectB` are strings. These are the ids of the objects to connect. These IDs are returned by addRect(), addDiamond(), addEllipse() and addText() when creating those objects.
+
+`connectionA` and `connectionB` specify where to connect on the object. Valid values are: "top", "bottom", "left", and "right".
+
+`numberOfPoints` set the number of interim break points for the line. Default value is zero, meaning there will be no breakpoint in between the start and the end points of the arrow. When moving objects on the drawing, these breakpoints will influence how the line is rerouted by Excalidraw.
+
+`startArrowHead` and `endArrowHead` work as described for `addArrow()` above.
+
+### addToGroup()
+```typescript
+addToGroup(objectIds:[]):void
+```
+Groups objects listed in `objectIds`.
+
+## Utility functions
+### clear()
+`clear()` will clear objects from cache, but will retain element style settings.
+
+### reset()
+`reset()` will first call `clear()` and then reset element style to defaults.
+
+### toClipboard()
+```typescript
+async toClipboard(templatePath?:string)
+```
+Places the generated drawing to the clipboard. Useful when you don't want to create a new drawing, but want to paste additional items onto an existing drawing.
+
+### create()
+```typescript
+async create(params?:{filename: string, foldername:string, templatePath:string, onNewPane: boolean})
+```
+Creates the drawing and opens it.
+
+`filename` is the filename without extension of the drawing to be created. If `null`, then Excalidraw will generate a filename.
+
+`foldername` is the folder where the file should be created. If `null` then the default folder for new drawings will be used according to Excalidraw settings.
+
+`templatePath` the filename including full path and extension for a template file to use. This template file will be added as the base layer, all additional objects added via ExcalidrawAutomate will appear on top of elements in the template. If `null` then no template will be used, i.e. an empty white drawing will be the base for adding objects.
+
+`onNewPane` defines where the new drawing should be created. `false` will open the drawing on the current active leaf. `true` will open the drawing by vertically splitting the current leaf.
+
+Example:
+```javascript
+create({filename:"my drawing", foldername:"myfolder/subfolder/", templatePath: "Excalidraw/template.excalidraw", onNewPane: true});
+```
+### createSVG()
+```typescript
+async createSVG(templatePath?:string)
+```
+Returns an HTML SVGSVGElement containing the generated drawing.
+
+### createPNG()
+```typescript
+async createPNG(templatePath?:string)
+```
+Returns a blob containing a PNG image of the generated drawing.
+
+## Examples
+### Insert new drawing into currently edited document
+This template will prompt you for the title of the drawing. It will create a new drawing with the provided title, and in the folder of the document you were editing. It will then transclude the new drawing at the cursor location and open the new drawing in a new workspace leaf by splitting the current leaf.
+
+*Use CTRL+Shift+V to paste code into Obsidian!*
+```javascript
+<%*
+  const defaultTitle = tp.date.now("HHmm")+' '+tp.file.title;
+  const title = await tp.system.prompt("Title of the drawing?", defaultTitle);
+  const folder = tp.file.folder(true);
+  const transcludePath = (folder== '/' ? '' : folder + '/') + title + '.excalidraw';
+  tR = String.fromCharCode(96,96,96)+'excalidraw\n[['+transcludePath+']]\n'+String.fromCharCode(96,96,96);
+  const ea = ExcalidrawAutomate;
+  ea.reset();
+  ea.setTheme(1); //set Theme to dark
+  await ea.create({
+    filename : title,
+    foldername : folder,
+    //templatePath: 'Excalidraw/Template.excalidraw', //uncomment if you want to use a template
+    onNewPane : true
+  });
+%>
+```
+
+### Connect objects
+*Use CTRL+Shift+V to paste code into Obsidian!*
+```javascript
+<%*
+  const ea = ExcalidrawAutomate;
+  ea.reset();
+  ea.addText(-130,-100,"Connecting two objects");
+  const a = ea.addRect(-100,-100,100,100);
+  const b = ea.addEllipse(200,200,100,100);
+  ea.connectObjects(a,"bottom",b,"left",{numberOfPoints: 2}); //see how the line breaks differently when moving objects around
+  ea.style.strokeColor = "red";
+  ea.connectObjects(a,"right",b,"top",1);
+  await ea.create();
+%>
+```
+### Using a template
+This example is similar to the first one, but rotated 90°, and using a template, plus specifying a filename and folder to save the drawing, and opening the new drawing in a new pane.
+
+*Use CTRL+Shift+V to paste code into Obsidian!*
+```javascript
+<%*
+  const ea = ExcalidrawAutomate;
+  ea.reset();
+  ea.style.angle = Math.PI/2; 
+  ea.style.strokeWidth = 3.5;
+  ea.addRect(-150,-50,450,300);
+  ea.addText(-100,70,"Left to right");
+  ea.addArrow([[-100,100],[100,100]]);
+
+  ea.style.strokeColor = "red";
+  await ea.addText(100,-30,"top to bottom",{width:200,textAlign:"center"});
+  ea.addArrow([[200,0],[200,200]]);
+  await ea.create({filename:"My Drawing",foldername:"myfolder/fordemo/",templatePath:"Excalidraw/Template2.excalidraw",onNewPane:true});
+%>
+```
+
+### Generating a simple mindmap from a text outline
+This is a slightly more elaborate example. This will generate an a mindmap from a tabulated outline.

-## Obsidian-Excalidraw
+The Obsidian-Excalidraw plugin integrates [Excalidraw](https://excalidraw.com/), a feature rich sketching tool, into Obsidian. You can store and edit Excalidraw files in your vault, you can embed drawings into your documents, and you can link to documents and other drawings to/and from Excalidraw. For a showcase of Excalidraw features, please read my blog post [here](https://www.zsolt.blog/2021/03/showcasing-excalidraw.html) and/or watch the videos below.
 
-### Key features
-- Use the Excalidraw command in the Command palette to open an existing drawing or to create a new one. You create a new one by typing its name and hitting enter.
-- Set up a default folder for your drawings in Settings. 
-- You can also set up a Template, by creating a drawing, customizing it the way you like, and specifying the file as the template in settings.
-- There is a known bug when inserting images from the library, in some cases these images will be placed out of view, and you'll need to select scroll to view at the bottom of the screen. The bug was reproduced by the Excalidraw dev team, so I expect in the next update of Excalidraw it will be fixed.
-- Translusion of drawings into markdown documents is not yet working.
-- Drawings are saved to your vault as a file with the extension .excalidraw
-- If you want to see these files in your vault you need to enable the following sestting

+Drawings you've created with version 1.1.x need to be converted to take advantage of the new features. If you want, you can also continue to use your exisiting drawings in compatibility mode (e.g. if you use Logseq and Obsidian in parallel). During conversion your existing `*.excalidraw` files will be replaced with new `*.excalidraw.md` files.
 
+## Conversion and compatibility
+To convert files you have the following options:
+- Click `CONVERT FILES` in the migration dialog when installing 1.2.0
+- In the Command Palette select `Excalidraw: Convert *.excalidraw files to *.excalidraw.md files` to convert all `*.excalidraw` files to `*.excalidraw.md` files. 
+- To convert files individually: 
+  - Right click an `*.excalidraw` file in File Explorer and select one of the following options:
+    - `*.excalidraw => *.excalidraw.md`
+    - `*.excalidraw => *.md (Logseq compatibility)`: This option will retain the original *.excalidraw file next to the new Obsidian format. Make sure you also enable additional `Compatibility features` in `Settings` for a full solution.
+  - Open a legacy `*.excalidraw` file and select `Convert to new format` from the `Options Menu` in the Excalidraw view.

+
+# Key features
+- The plugin aims to integrate Excalidraw seemlessly into Obsidian including Command Palette actions, File Explorer features, Option Menu commands, and the Ribbon Button.
+- CTRL+Click on the ribbon button, or in the file explorer to create / open drawings in a new pane.
+- Settings will allow you to customzie Excalidraw to your needs:
+  - Default folder for new drawings and define custom filename pattern for new drawings.
+  - Template for new drawings. The template will restore stroke properties. This means you can set up defaults in your template for stroke color, stroke width, opacity, font family, font size, fill style, stroke style, etc. This also applies to ExcalidrawAutomate.
+  - If portability is important to you: Auto-export SVG and/or PNG files including keep-in-sync feature so you can embed svg/png into your documents instead of embedding excalidraw files.
+  - Specify the default width of embedded drawings.
+  - Compatibility features to auto-export and keep in sync markdown excalidraw files and legacy .excalidraw files.
+  - Experimental feature to add custom TAG to file expolorer to mark drawing files.
+  - Enable / disable autosave.
+- You can customize the size and position of the embedded images using the `[[image.excalidraw|100]]`, `[[image.excalidraw|100x100]]`, `[[image.excalidraw|100|left]]`, `[[image.excalidraw|right-wrap]]`, formatting options. `[[<filename.excalidraw>|<width>x<height>|<alignment>]]`. You can add your custom alignment via css. Any text that appears in `<alignment>` will be added to the rendered SVG element style and to the wrapper DIV element. Check below and styles.css for more insight.
+- Supports hyperlinks e.g. `https://zsolt.blog`, `[Obsidian](https://obsidian.md)`, and internal links e.g. `[[My file in vault|Alias]]` in drawing text. 
+  - Links will update when files are moved or renamed, if you have the Obsidian setting Files & Links/Automatically Update Internal Links enalbled.
+  - Links in drawings will show up in backlinks of documents
+  - Transclusions are supported 
+    - `![[myfile#^blockref]]` will convert in the drawing into the transcluded text of the block
+    - `![[myfile#section]]` also works, this will transclude the section
+    - you can also specify word wrapping for transcluded text by adding the max character count in curly brackets right after the transclusion e.g. `![[myfile#^blockref]]{40}` will wrap text at 40 characters.
+  - For convenience you can also use the command palette to insert links into drawings
+  - CTRL/META + hover to bring up the Obsidian quick preview for the link. (On Mac it is CTRL+CMD+hover).
+  - CTRL/META + CLICK a text element to open it as a link.
+  - CTRL/META + ALT + CLICK to create the file (if it does not yet exist) and open it
+  - CTRL/META + SHIFT + CLICK to open the file in a new pane
+  - CTRL/META + ALT + SHIFT + CLICK to create the file (if it does not yet exist) and open it in a new pane
+- Using the block reference you can also reference & transclude text that appears on drawings, in other documents
+- Insert LaTex symbols and simple formulas using the Command Palette action "Insert LaTeX-symbol". Some symbols may not display properly using the "Hand-drawn" font. If that is the case try using the "Normal" or "Code" fonts.
+- Since 1.2.0 Drawing files are stored in Markdown files
+  - You can add tags to drawings
+  - You can add metadata to the YAML front matter of drawings
+  - Anything you add between the frontmatter and the `# Text Elements` heading will be ignored by Excalidraw, i.e. you can add whatever you like here, it will be preserved as part of the document.
+  - Excalidraw documents now show in graph view.
+  - The following front matter keys will customize how the drawing is displayed - overriding general settings:
+    - `excalidraw-link-prefix: "📍"` preview prefix for internal links
+    - `excalidraw-url-prefix: "🌐"` preview prefix for external links
+    - `excalidraw-link-brackets: true|false` whether or not to display brackets around links in preview
+- Includes full [Templater](https://silentvoid13.github.io/Templater/) and [Dataview](https://blacksmithgu.github.io/obsidian-dataview/docs/api/intro/) support through ExcalidrawAutomate. Check out the [detailed help + examples](https://zsviczian.github.io/obsidian-excalidraw-plugin/)
+- REQUIRES AN OBSIDIAN SYNC SUBSCRIPTION: Full drawing file history and synchronization between devices
+- Multilanguage support: if you'd like to help out by translating the plugin, please get in contact with me.
+
+# Known issues
+- Mobile support
+  - Positioning of the pen gets misaligned after you open the command palette.
+  - Partially mitigated in 1.0.10 by the introduction of autosave: Your drawing will not be saved when you terminate the mobile app by closing the Obsidian task. 
+
+# Tips and tricks
+- If you want to sketch in fullscreen, I recommend installing the [Fullscreen Focus Mode](https://github.com/razumihin/obsidian-fullscreen-plugin) plugin.
+- [Ozan's Image in Editor Plugin](https://github.com/ozntel/oz-image-in-editor-obsidian). In a nice collaboration with Ozan, his Image-in-Editor plugin now supports Excalidraw. I recommend installing his plugin to display drawings also in Edit mode. Note that Ozan's plugin will only display Excalidraw drawings if the link ends with `.md` or `.excalidraw`. i.e. the following drawing will show in Edit Mode `![[My Drawing.md]]`, but wiki links such as `[[My Drawing]]` will not.

+# [◀ Excalidraw Automate How To](../readme.md)
+## Introduction to the API
+You can access Excalidraw Automate via the ExcalidrawAutomate object. I recommend starting your Automate scripts with the following code:
+
+*Use CTRL+Shift+V to paste code into Obsidian!*
+```javascript
+const ea = ExcalidrawAutomate;
+ea.reset();
+```
+
+The first line creates a practical constant so you can avoid writing ExcalidrawAutomate 100x times.
+
+The second line resets ExcalidrawAutomate to defaults. This is important as you will not know which template you executed before, thus you won't know what state you left Excalidraw in.
+
+### Basic logic of using Excalidraw Automate
+1. Set the styling of the elements you want to draw
+2. Add elements. As you add elements, each new element is added one layer above the previous, thus in case of overlapping objects the later one will be on the top of the prior one.
+3. Call `await ea.create();` to instantiate the drawing, or use `ea.setView();` followed by `ea.addElementsToView();` to add your elements to an existing view, or create a PNG or SVG image out of your elements using `await ea.createSVG();` or `await ea.createPNG();`;
+
+You can change the styling between adding different elements. My logic for separating element styling and creation is based on the assumption that you will probably set a stroke color, stroke style, stroke roughness, etc. and draw most of your elements using that. There would be no point in setting all these parameters each time you add an element.
+
+### Before we dive deeper, here are three a simple example Templater scripts
+#### Create a new drawing with custom name, in a custom folder, using a template
+This simple script gives you significant additional flexibility over Excalidraw Plugin settings to name your drawings, place them into folders, and to apply templates.
+
+*Use CTRL+Shift+V to paste code into Obsidian!*
+```javascript
+<%*
+  const ea = ExcalidrawAutomate;
+  ea.reset();
+  await ea.create({
+    filename    : tp.date.now("HH.mm"), 
+    foldername  : tp.date.now("YYYY-MM-DD"),
+    templatePath: "Excalidraw/Template1.excalidraw",
+    onNewPane   : false
+  });
+%>
+```
+
+#### Create a simple drawing
+*Use CTRL+Shift+V to paste code into Obsidian!*
+```javascript
+<%*
+  const ea = ExcalidrawAutomate;
+  ea.reset();
+  ea.addRect(-150,-50,450,300);
+  ea.addText(-100,70,"Left to right");
+  ea.addArrow([[-100,100],[100,100]]);
+
+  ea.style.strokeColor = "red";
+  ea.addText(100,-30,"top to bottom",{width:200,textAligh:"center"});
+  ea.addArrow([[200,0],[200,200]]);
+  await ea.create();
+%>
+```
+The script will generate the following drawing:

+
+#### Add a TextElement in a box to an open Excalidraw View. 
+Position the new element under the currently selected element, with an arrow from the selected element to the added text.
+
+*Use CTRL+Shift+V to paste code into Obsidian!*
+```javascript

+  ea.reset();

+  selectedElement = ea.getViewSelectedElement();
+  ea.setStrokeSharpness(0);

+## Adding objects
+These functions will add objects to your drawing. The canvas is infinite, and it accepts negative and positive X and Y values. X values increase left to right, Y values increase top to bottom.
+
+![coordinates](https://user-images.githubusercontent.com/14358394/116825632-6569b980-ab90-11eb-827b-ada598e91e46.png)
+
+### addRect(), addDiamond(), addEllipse()
+```typescript
+addRect(topX:number, topY:number, width:number, height:number):string
+addDiamond(topX:number, topY:number, width:number, height:number):string
+addEllipse(topX:number, topY:number, width:number, height:number):string
+```
+Returns the `id` of the object. The `id` is required when connecting objects with lines. See later.
+
+### addText()
+```typescript
+addText( 
+  topX:number, 
+  topY:number, 
+  text:string, 
+  formatting?:{
+    wrapAt?:number, 
+    width?:number, 
+    height?:number,
+    textAlign?:string, 
+    box?: "box"|"blob"|"ellipse"|"diamond", 
+    boxPadding?:number
+  },
+  id?:string
+):string
+```
+
+Adds text to the drawing. 
+
+Formatting parameters are optional:
+- If `width` and `height` are not specified, the function will calculate the width and height based on the fontFamily, the fontSize and the text provided.
+- In case you want to position a text in the center compared to other elements on the drawing, you can provide a fixed height and width, and you can also specify `textAlign` and `verticalAlign` as described above. e.g.: `{width:500, textAlign:"center"}`
+- If you want to add a box around the text, set `{box:"box"|"blob"|"ellipse"|"diamond"}`
+
+Returns the `id` of the object. The `id` is required when connecting objects with lines. See later. If `{box:}` then returns the id of the enclosing box object.
+
+### addLine()
+```typescript
+addLine(points: [[x:number,y:number]]):string
+```
+Adds a line following the points provided. Must include at least two points `points.length >= 2`. If more than 2 points are provided the interim points will be added as breakpoints. The line will break with angles if `strokeSharpness` is set to "sharp" and will be curvey if it is set to "round".
+
+Returns the `id` of the object.
+
+### addArrow()
+```typescript
+addArrow(points: [[x:number,y:number]],formatting?:{startArrowHead?:string,endArrowHead?:string,startObjectId?:string,endObjectId?:string}):string ;
+```
+
+Adds an arrow following the points provided. Must include at least two points `points.length >= 2`. If more than 2 points are provided the interim points will be added as breakpoints. The line will break with angles if element `style.strokeSharpness` is set to "sharp" and will be curvey if it is set to "round".
+
+`startArrowHead` and `endArrowHead` specify the type of arrow head to use, as described above. Valid values are "none", "arrow", "dot", and "bar". e.g. `{startArrowHead: "dot", endArrowHead: "arrow"}`
+
+`startObjectId` and `endObjectId` are the object id's of connected objects. I recommend using `connectObjects` instead calling addArrow() for the purpose of connecting objects.
+
+Returns the `id` of the object.
+
+### connectObjects()
+```typescript
+declare type ConnectionPoint = "top"|"bottom"|"left"|"right";
+connectObjects(objectA: string, connectionA: ConnectionPoint, objectB: string, connectionB: ConnectionPoint, formatting?:{numberOfPoints: number,startArrowHead:string,endArrowHead:string, padding: number}):void
+```
+Connects two objects with an arrow. Will do nothing if either of the two elements is of type `line`, `arrow`, or `freedraw`.
+
+`objectA` and `objectB` are strings. These are the ids of the objects to connect. These IDs are returned by addRect(), addDiamond(), addEllipse() and addText() when creating those objects.
+
+`connectionA` and `connectionB` specify where to connect on the object. Valid values are: "top", "bottom", "left", and "right".
+
+`numberOfPoints` set the number of interim break points for the line. Default value is zero, meaning there will be no breakpoint in between the start and the end points of the arrow. When moving objects on the drawing, these breakpoints will influence how the line is rerouted by Excalidraw.
+
+`startArrowHead` and `endArrowHead` work as described for `addArrow()` above.
+
+### addToGroup()
+```typescript
+addToGroup(objectIds:[]):string
+```
+Groups objects listed in `objectIds`. Returns the `id` of the group.

+# [◀ Excalidraw Automate How To](../readme.md)
+## Utility functions
+### isExcalidrawFile()
+```typescript
+isExcalidrawFile(f:TFile): boolean
+```
+Returns true if the file provided is a valid Excalidraw file (either a legacy `*.excalidraw` file or a markdown file with the excalidraw key in the front-matter).
+
+### clear()
+`clear()` will clear objects from cache, but will retain element style settings.
+
+### reset()
+`reset()` will first call `clear()` and then reset element style to defaults.
+
+### toClipboard()
+```typescript
+async toClipboard(templatePath?:string)
+```
+Places the generated drawing to the clipboard. Useful when you don't want to create a new drawing, but want to paste additional items onto an existing drawing.
+
+### getElements()
+```typescript
+getElements():ExcalidrawElement[];
+```
+Returns the elements in ExcalidrawAutomate as an array of ExcalidrawElements. This format is usefull when working with ExcalidrawRef.
+
+### getElement()
+```typescript
+getElement(id:string):ExcalidrawElement;
+```
+
+Returns the element object matching the id. If the element does not exist, returns null.
+
+### create()
+```typescript
+async create(params?:{filename: string, foldername:string, templatePath:string, onNewPane: boolean})
+```
+Creates the drawing and opens it. Returns the full filepath of the created file.
+
+`filename` is the filename without extension of the drawing to be created. If `null`, then Excalidraw will generate a filename.
+
+`foldername` is the folder where the file should be created. If `null` then the default folder for new drawings will be used according to Excalidraw settings.
+
+`templatePath` the filename including full path and extension for a template file to use. This template file will be added as the base layer, all additional objects added via ExcalidrawAutomate will appear on top of elements in the template. If `null` then no template will be used, i.e. an empty white drawing will be the base for adding objects.
+
+`onNewPane` defines where the new drawing should be created. `false` will open the drawing on the current active leaf. `true` will open the drawing by vertically splitting the current leaf.
+
+`frontmatterKeys` are the set of frontmatter keys to apply to the document
+  {
+    excalidraw-plugin?: "raw"|"parsed",
+    excalidraw-link-prefix?: string,
+    excalidraw-link-brackets?: boolean,
+    excalidraw-url-prefix?: string
+  }
+
+Example:
+```javascript
+create (
+  {
+    filename:"my drawing", 
+    foldername:"myfolder/subfolder/", 
+    templatePath: "Excalidraw/template.excalidraw", 
+    onNewPane: true, 
+    frontmatterKeys: {
+      "excalidraw-plugin": "parsed",
+      "excalidraw-link-prefix": "",
+      "excalidraw-link-brackets": true,
+      "excalidraw-url-prefix": "🌐",
+    }
+  }
+);
+```
+### createSVG()
+```typescript
+async createSVG(templatePath?:string)
+```
+Returns an HTML SVGSVGElement containing the generated drawing.
+
+### createPNG()
+```typescript
+async createPNG(templatePath?:string, scale:number=1)
+```
+Returns a blob containing a PNG image of the generated drawing.
+
+### wrapText()
+```typescript
+wrapText(text:string, lineLen:number):string
+```
+Returns a string wrapped to the provided max lineLen.
+
+
+### Accessing the open Excalidraw view
+You first need to initialize targetView, before using any of the view manipulation functions.
+
+#### targetView
+```typescript
+targetView: ExcalidrawView
+```
+The open Excalidraw View configured as the target of the view operations. User `setView` to initialize.
+
+#### setView()
+```typescript
+setView(view:ExcalidrawView|"first"|"active"):ExcalidrawView
+```
+Setting the ExcalidrawView that will be the target of the View operations. Valid `view` input values are:
+- an object instance of ExcalidrawView
+- "first": meaning if there are multiple Excalidraw Views open, pick the first that is returned by `app.workspace.getLeavesOfType("Excalidraw")`
+- "active": meaning the currently active view
+
+#### getExcalidrawAPI()
+```typescript
+getExcalidrawAPI():any
+```
+Returns the native Excalidraw API (ref.current) for the active drawing specified in `targetView`.
+See Excalidraw documentation here: https://www.npmjs.com/package/@excalidraw/excalidraw#ref
+
+#### getViewElements()
+```typescript
+getViewElements():ExcalidrawElement[] 
+```
+
+Returns all the elements from the view.
+
+#### deleteViewElements()
+```typescript
+deleteViewElements(elToDelete: ExcalidrawElement[]):boolean 
+```
+
+Deletes those elements from the view that match the elements provided as the input parameter.
+
+Example to delete the selected elements from the view:
+```typescript
+ea = ExcalidrawAutomate;
+ea.setView("active");
+el = ea.getViewSelectedElements();
+ea.deleteViewElements();
+```
+
+#### getViewSelectedElement()
+```typescript
+getViewSelectedElement():ExcalidrawElement
+```
+
+You first need to set the view calling `setView()`.
+
+If an element is selected in the targetView the function returns the selected element. If multiple elements are selected, either by SHIFT+Clicking to select multiple elements, or by selecting a group, the first of the elements will be selected. If you want to specify which element to select from a group, double click the desired element in the group.
+
+This function is helpful if you want to add a new element in relation to an existing element in your drawing.
+
+#### getViewSelectedElements()
+```typescript
+getViewSelectedElements():ExcalidrawElement[]
+```
+
+You first need to set the view calling `setView()`.
+
+Gets the array of selected elements in the scene. Returns [] if no elements are selected.
+
+Note: you can call `getExcalidrawAPI().getSceneElements()` to retreive all the elements in the scene.
+
+#### viewToggleFullScreen()
+```typescript
+viewToggleFullScreen(forceViewMode?:boolean):void;
+```
+
+Toggles targetView between fullscreen mode and normal mode. By setting forceViewMode to `true` will change Excalidraw mode to View mode. Default is `false`.
+
+The function will do nothing on Obsidian Mobile.
+
+#### connectObjectWithViewSelectedElement()
+```typescript 
+connectObjectWithViewSelectedElement(objectA:string,connectionA: ConnectionPoint, connectionB: ConnectionPoint, formatting?:{numberOfPoints?: number,startArrowHead?:string,endArrowHead?:string, padding?: number}):boolean
+```
+Same as `connectObjects()`, but ObjectB is the currently selected element in the target ExcalidrawView. The function helps with placing an arrow between a newly created object and the selected element in the target ExcalidrawView.
+
+#### addElementsToView()
+```typescript
+async addElementsToView(repositionToCursor:boolean=false, save:boolean=false):Promise<boolean>
+```
+Adds elements created with ExcalidrawAutomate to the target ExcalidrawView.
+`repositionToCursor` dafault is false
+- true: the elements will be moved such that the center point of the elements will be aligned with the current position of the pointer on ExcalidrawView. You can point and place elements to a desired location in your drawing using this switch.
+- false: elements will be positioned as defined by the x&y coordinates of each element.
+
+`save` default is false
+- true: the drawing will be saved after the elements were added.
+- false: the drawing will be saved at the next autosave cycle. Use false when adding multiple elements one after the other. Else, best to use true, to minimize risk of data loss.
+
+### onDropHook
+```typescript
+onDropHook (data: {
+  ea: ExcalidrawAutomate, 
+  event: React.DragEvent<HTMLDivElement>,
+  draggable: any, //Obsidian draggable object
+  type: "file"|"text"|"unknown",
+  payload: {
+    files: TFile[], //TFile[] array of dropped files
+    text: string, //string 
+  },
+  excalidrawFile: TFile, //the file receiving the drop event
+  view: ExcalidrawView, //the excalidraw view receiving the drop
+  pointerPosition: {x:number, y:number} //the pointer position on canvas at the time of drop
+}):boolean;
+```
+
+Callback function triggered when an draggable item is dropped on Excalidraw.
+The function should return a boolean value. True if the drop was handled by the hook and futher native processing should be stopped, and false if Excalidraw should continue with the processing of the drop.
+type of drop can be one of:
+- "file" if a file from Obsidian file explorer is dropped onto Excalidraw. In this case payload.files will contain the list of files dropped.
+- "text" if a link (e.g. url, or wiki link) or other text is dropped. In this case payload.text will contain the received string
+- "unknown" if Excalidraw plugin does not recognize the type of dropped object. In this case you can use React.DragEvent to analysed the dropped object.
+
+Use Templater startup templates or similar to set the Hook function. 
+
+```typescript
+ea = ExcalidrawAutomate;
+ea.onDropHook = (data) => {
+  console.log(data); 
+  return false;
+}
+```

+# Excalidraw Automate How To
+
+Excalidraw Automate allows you to create Excalidraw drawings using the [Templater](https://silentvoid13.github.io/Templater/docs/) plugin, and to generate embedded SVG and PNG images using [DataviewJS](https://blacksmithgu.github.io/obsidian-dataview/docs/api/intro/)
+
+With a little work, using Excalidraw Automate you can generate simple mindmaps, build a family tree, fill out SVG forms, create customized charts, etc. based on documents in your vault.
