 ## Key features
-- The plugin adds the following actions to the **command palette**:
-  - To create a new drawing
-  - To find and edit existing drawings in your vault, 
-  - To embed (transclude) a drawing into a document, and
-  - To export a drawing as PNG or SVG.
-- You can also use the **file explorer** in your vault to open Excalidraw files. 
-- Use the **ribbon button** to create a new drawing, do CTRL+Click to open on a new page.
-- Open settings to set up a **default folder** for new drawings. 
-- Set up a **Template** by creating a drawing, customizing it the way you like it, and specifying the file as the template in settings.
 - The plugin saves drawings to your vault as a file with the *.excalidraw* file extension.
-- You can customize 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.
-- You can setup Excalidraw to **automatically export SVG and/or PNG** files for your drawings, and to keep those in sync with your 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.
 
 ## Known issues
-- 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. I understand that the issue will be resolved in the next release of Obsidian mobile. 
 - 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.
-- Sync does not support .excalidraw files. This issue will be addressed in a later release of Obsidian sync. Until then, here are two hacks you can play with: 
-  - You have the option to use OneDrive, Google Drive, iCloud, DropBox, etc. to sync your vault between devices.
-  - You can also use Obsidian Sync in conjunction with "Obsidian Git" (find it in community plugins). Be sure to set up git to ignore all files except for .excalidraw by adding the following to `.gitignore`. Obsidian Git does not work on mobile, but on Android you can use an app like MGIT to sync your `.excalidraw` files from/to the git repository.
-  ```
-  #ignore all kind of files
-  *.*
-  #except excalidraw files
-  !*.excalidraw
-  ```
+- 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.

+# [◀ Excalidraw Automate How To](../readme.md)
+## Introduction to the API
+You can access Excalidraw Automate via the ExcalidrawAutomate object. I recommend staring 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.

+  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();

+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 exising 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.
