+# 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:
+*Use CTRL+Shift+V to paste code into Obsidian!*

+
+## 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
+String. This is the fill color of an object. [CSS Legal Color Values](https://www.w3schools.com/cssref/css_colors_legal.asp)

+
+### 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
+
+### textAlign
+String. Alignment of the text horizontally. Valid values are "left", "center", "right".
+
+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 and you can transclude drawings into your documents. 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

+Thank you for updating to Excalidraw 1.1.x!
 
-### Known bug registered with Excalidraw

+I have improved how drawings are embedded! You no longer need an Excalidraw codeblock. You can now embed drawings just like any other images: `![[my drawing.excalidraw]]` or `![[my drawing.excalidraw|500|left]]` or `![[my drawing.excalidraw|right-wrap]]`, `![alttext|500|right](drawing.excalidraw)`, `![](folder/drawing.excalidraw)`, etc. You get the idea.

+# Key features
+- The plugin saves drawings to your vault as a file with the *.excalidraw* file extension.
+- The plugin adds the following actions to the **command palette**:
+  - Create a new drawing
+  - Find and edit existing drawings in your vault, 
+  - Transclude (embed) a drawing into a document, and
+  - Export a drawing as PNG or SVG.
+- You can also use the **file explorer** in your vault to open existing Excalidraw files. 
+- Use the **ribbon button** to create a new drawing, CTRL+Click to open on a new page.
+- Open settings to set up
+  - a **default folder** for new drawings, 
+  - a **Template** by first creating a drawing, customizing it the way you like it, and specifying the file as the template in settings,
+  - Excalidraw to **automatically export SVG and/or PNG** files for your drawings, and to keep those in sync with your drawing,
+  - default width of embedded drawings 
+- You can also ustomize the **size and position of the embedded image** 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 as style to the SVG element and the wrapper DIV element. Check below and styles.css for more insight.
+- Includes full [Templater](https://silentvoid13.github.io/Templater/) and [Dataview](https://blacksmithgu.github.io/obsidian-dataview/docs/api/intro/) support through ExcalidrawAutomate. Read detailed help + examples: [here](https://zsviczian.github.io/obsidian-excalidraw-plugin/)
+- REQUIRES AN OBSIDIAN SYNC SUBSCRIPTION: Temporary hack/workaround to enable Obsidian Sync for Excalidraw files. This enables almost real-time two-way sync for Excalidraw files between your devices. You can draw on your iPad with your pencil, on your Android with your stylus, and the image will be available in Obsidian on your desktop as well and vice versa.

+
+# Release Notes
+
+## 1.1.6
+[![Obsidian-Excalidraw 1.1.6 - Links](https://user-images.githubusercontent.com/14358394/119559279-bdb46580-bda2-11eb-88cb-7614dc452034.jpg)](https://youtu.be/FDsMH-aLw_I)
+
+## 1.1.5
+- The template will now 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.
+- Added settings to customize the autogenerated filename
+- Minor fixes for occasional console.log errors.
+
+## 1.1.0
+- ALT+Enter and CTRL+ALT+Enter on the filename in edit mode will open up the Excalidraw editor. Click and CTRL+Click on the image in preview mode will also bring up the Excalidraw editor as expected.
+- I have also added two new Command Palette commands. Both create a new drawing and immediately embed it in the document you are editing, one will open the drawing in a new workspace pane, the other within the currently active pane.
+- [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.
+
+### MIGRATION to 1.1.0
+I have added a Migration command to the Command Palette. When you select this, the program will run a search and replace for all the excalidraw codeblocks in your vault and will convert them to the new format.
+
+## 1.0.12 Freehand drawing
+- now includes the new freehand drawing features from Excalidraw.com
+- If you use Obsydian sync with Excalidraw sync, be sure to update all your devices to the new version, as the old excalidraw will simply delete the freehand drawn images and/or simply not show the drawing.
+
+### Temporary workaround - use it only if you are ok with hacky solutions
+- I implemented a temporary workaround to enable Obsidian Sync for Excalidraw files. This enables almost real-time two-way sync between your devices. You can draw on your iPad with your pencil, on your Android with your stylus, and the image will be available in Obsidian as well and vice versa. 
+- By enabling this feature Excalidraw will sync drawings to a sync folder where drawings are stored in an ".md" file. This will allow Obsidian sync to synchronize Excalidraw drawings as well... Whenever your drawing changes, the corresponding file in the sync folder will also get updated. Similarly, whenever a file is synchronized to the sync folder by Obsidian sync, Excalidraw will sync it with the .excalidraw file in your vault.
+- Because this is a temporary workaround until Obsidian sync is ready, I didn't implement extensive application logic to manage sync. Sync might get confused requiring some manual intervention.
+
+### QoL improvement
+- I added an autosave feature. Your active drawing gets saved every 30 seconds if you've made changes to it. Drawings otherwise get saved when the window loses focus, or when you close the drawing, etc. Autosave limits the risk of accidental data loss on mobiles when you "swipe out" Obsidian to close it.
+
+## 1.0.10 
+[![Obsidian-Excalidraw 1.0.10 update](https://user-images.githubusercontent.com/14358394/117579017-60a58800-b0f1-11eb-8553-7820964662aa.jpg)](https://youtu.be/W7pWXGIe4rQ)
+ 
+## 1.0.8 and 1.0.9 (minor fixes)  
+[![Obsidian-Excalidraw 1.0.8 update](https://user-images.githubusercontent.com/14358394/117492534-029e6680-af72-11eb-90a3-086e67e70c1c.jpg)](https://youtu.be/AtEhmHJjnxM)
+
+### QoL improvements
+- Adds context menu to File Explorer to create new drawings
+- Adds a new command to the palette: “Transclude (embed) the most recently edited Excalidraw drawing”
+- Automatically update file-links in transclusions when you rename or move your drawing
+- Saves drawing and updates all active pre-views when drawing loses focus
+- File is closed and removed when you select “Delete file” from more options
+- Saves drawing when exiting Obsidian
+- Fixes pen positioning bug with sliding panes after panes scroll
+
+### ExcalidrawAutomte full Templater and DataviewJS support
+You now have ultimate flexibility over your Excalidraw templates using Templater and Dataview.
+- Detailed documentation available [here](https://zsviczian.github.io/obsidian-excalidraw-plugin/)
+- I created few examples from the simple to the more complex
+	- Simple use-case: Creating a drawing using a custom template and following a file and folder naming convention of your choice.
+	- Complex use-case: Create a mindmap from a tabulated outline.
+  ![Drawing 2021-05-05 20 52 34](https://user-images.githubusercontent.com/14358394/117194124-00a69d00-ade4-11eb-8b75-5e18a9cbc3cd.png)
+ 
+## 1.0.6 and 1.0.7 
+[![1.0.6 Update](https://user-images.githubusercontent.com/14358394/116312909-58725200-a7ad-11eb-89b9-c67cb48ffebb.jpg)](https://youtu.be/ipZPbcP2B0M)
+
+### SVG styling when embedding
+- 1.0.7 adds further flexibility to styling
+- new formatting option for the code block embedding
+- Valid values: `left`, `right`, `left-wrap`, `right-wrap`... but anything after the last `|` character will be added to the class of the SVG element and the wrapper DIV element.
+Here is the corresponding CSS:
+```css
+img.excalidraw-svg-right-wrap {
+  float: right;
+  margin: 0px 0px 20px 20px;
+}
+
+img.excalidraw-svg-left-wrap {
+  float: left;
+  margin: 0px 35px 20px 0px;
+}
+
+img.excalidraw-svg-right {
+  float: right;
+}
+
+img.excalidraw-svg-left {
+  float: left;
+}
+
+div.excalidraw-svg-right,
+div.excalidraw-svg-left {
+  display: table;
+  width: 100%;
+}
+```
+
+# Known issues
+- I have seen two cases when adding a stencil library did not work. In both cases, the end solution was a reinstall of Obsidian. The root cause is not clear, but maybe because of  the incremental updates of Obsidian from an early version.
+- 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. 
+### Resolved known issues:
+- Resolved with 1.0.10 Temporary workaround: 
+  - Sync does not support .excalidraw files. This issue will be addressed in a later release of Obsidian sync. Until then, you can use my temporary workaround. 
+- Resolved with Obsidian mobile 0.18: 
+  - On mobile (iOS and Android): As you draw left to right it opens left sidebar. Draw right to left, opens right sidebar. Draw down, opens commands palette. So seems open is emulating the gestures, even when drawing towards the center. 
+
+# 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.

+# [◀ 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
+
+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:
+
+![FristDemo](https://user-images.githubusercontent.com/14358394/116825643-6e5a8b00-ab90-11eb-9e3a-37c524620d0d.png)

+## 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.
