# Excalidraw Script Library Examples

This is an automatically generated knowledge base intended for Retrieval Augmented Generation (RAG) and other AI-assisted workflows (e.g. NotebookLM or local embeddings tools).  
Its purpose:
- Provide a single, query-friendly corpus of all Excalidraw Automate scripts.
- Serve as a practical pattern and snippet library for developers learning Excalidraw Automate.
- Preserve original source side by side with the higher-level index (index-new.md) to improve semantic recall.
- Enable AI tools to answer questions about how to manipulate the Excalidraw canvas, elements, styling, or integration features by referencing real, working examples.

Content structure:
1. SCRIPT_INTRO (this section)
2. The curated script overview (index-new.md)
3. Raw source of every *.md script in /ea-scripts (each fenced code block is auto-closed to ensure well-formed aggregation)

# Introducing Excalidraw Automate Script Engine
<a href="https://www.youtube.com/watch?v=hePJcObHIso" target="_blank"><img src ="https://i.ytimg.com/vi/hePJcObHIso/maxresdefault.jpg" style="width:560px;"></a>

Script Engine scripts are installed in the `Downloaded` subfolder of the `Excalidraw Automate script folder` specified in plugin settings.

In the `Command Palette` installed scripts are prefixed with `Downloaded/`, thus you can always know if you are executing a local script of your own, or one that you have downloaded from GitHub.

## Create Your Own Scripts with AI Superpowers

You don't need to know how to code to build custom scripts! In this video, I show how to create powerful, custom Excalidraw scripts from scratch using the power of AI. 

Follow along as I generate a complete Layer Manager script for Excalidraw in Obsidian, allowing you to hide, show, lock, and manage elements on different layers. I'll walk you through the entire process, from using a custom training library for Excalidraw Automate to prompting Google's Gemini AI Studio to write the code for us. Discover how to unlock a true superpower for your Obsidian and Excalidraw workflow by generating any script you can imagine.

## Attention developers and hobby hackers
<img src='https://raw.githubusercontent.com/zsviczian/obsidian-excalidraw-plugin/master/images/hobby-programmer.svg' align='left' style='background-color:whitesmoke; width:80px; margin-right:15px; margin-bottom:10px;'/>
If you want to modify scripts, I recommend moving them to the `Excalidraw Automate script folder` or a different subfolder under the script folder. Scripts in the `Downloaded` folder will be overwritten when you click the `Update this script` button. Note also, that at this time, I do not check if the script file has been updated on GitHub, thus the `Update this script` button is always visible once you have installed a script, not only when an update is available (hope to build this feature in the future).

I would love to include your contribution in the script library. If you have a script of your own that you would like to share with the community, please open a [PR](https://github.com/zsviczian/obsidian-excalidraw-plugin/pulls) on GitHub. Be sure to include the following in your pull request
- The [script file](https://github.com/zsviczian/obsidian-excalidraw-plugin/tree/master/ea-scripts) with a self explanetory name. The name of the file will be the name of the script in the Command Palette.
- An [image](https://github.com/zsviczian/obsidian-excalidraw-plugin/tree/master/images) explaining the scripts purpose. Remember a picture speaks thousand words!
- An update to this file [ea-scripts/index-new.md](https://github.com/zsviczian/obsidian-excalidraw-plugin/blob/master/ea-scripts/index-new.md)

## Editors Picks
These are the scripts I use most often. I tried to order them by importance, but usefulness is situational—some days Crop Vintage Mask is as helpful as Deconstruct Selected Elements. I do deconstruct drawings daily; the entries lower in the Editors’ Picks list are still valuable, just needed less frequently.

## Boolean Operations.md
<!-- Source: ea-scripts/Boolean Operations.md -->

/*
With This Script it is possible to make boolean Operations on Shapes. 
The style of the resulting shape will be the style of the highest ranking Element that was used. 
The ranking of the elements is based on their background. The "denser" the background, the higher the ranking (the order of backgroundstyles is shown below). If they have the same background the opacity will decide. If thats also the same its decided by the order they were created.
The ranking is also important for the difference operation, so a transparent object for example will cut a hole into a solid object.

This script will add encapsulating boxes around each of the currently selected groups in Excalidraw.

You can focus on content creation first, and then batch add consistent style boxes to each group of text.

Tips 1: You can copy the desired style to the global state using script `Copy Selected Element Style to Global`, then add boxes with the same global style using script `Box Each Selected Groups`.

Tips 2: Next you can use scripts `Expand rectangles horizontally keep text centered` and `Expand rectangles vertically keep text centered` to make the boxes the same size, if you wish.

Tips 3: If you want the left and right margins to be different from the top and bottom margins, input something like `32,16`, this will create a box with left and right margins of `32` and top and bottom margins of `16`.

See documentation for more details:

## Capture Note.md
<!-- Source: ea-scripts/Capture Note.md -->

/*
This script implements the unified "Capture Note" workflow, allowing users to select or search for note titles, automatically resolve their template and folder rules, and contextually back-embed visual frames or markdown sections.

![Visual Daily Notes + TODOs in Context: Obsidian Excalidraw, Tasks, Templater, Dataview, ExcaliBrain](https://youtu.be/y3sDfH30ApU)

# Technical Specification: Visual-First Contextual Capture System

## 1. Scope & Objective
This specification dictates the operational logic and flow for a "Capture Note" script running within the `ExcalidrawAutomate` plugin for Obsidian. It creates an integrated environment where ideas are linked continuously between "Originating Notes" (Note A) and "Target Topic Notes" (Note B) using structural visual frames and contextual markdown embeds.

## 2. Global State & Settings (`DNP Config`)
Settings are persisted in Excalidraw's global script settings under the explicit script name `DNP Config` and memory-managed under `window.ExcalidrawCaptureNoteScript` to handle temporary search text tracking across modal lifecycles.

### NoteTypeConfig Schema
Users can configure unlimited dynamic Note Types containing:
*   `folder` (Destination vault path)
*   `template` (Associated `.md` Templater template, extensions cleanly resolved)
*   `prefix` (e.g., `IIB - `)
*   `type` (`file` or `folder`-nested)
*   `icon` (Lucide icon identifier)
*   `ontology` (Action verbs like `reading`, `discussing` for ExcaliBrain/Dataview linkages)

## 3. Modal User Interfaces

### Capture Note Modal (Floating Modal)
*   **Search Box:** Intercepts inputs natively. Uses a custom dropdown logic. Up/Down/Enter keys traverse the auto-complete dropdown, blocking upstream events to prevent the modal from erroneously closing or the FloatingModal calss grabbing the inputs.
*   **Property Autofill:** If a file is searched and matches an existing file, the script parses the document for the `Note type` (in YAML frontmatter or Dataview inline fields) and locks the Link Type to match.
*   **Tab Sequencing:** Enforced structurally via `flex-direction: row-reverse`. Upon tabbing past the ontology dropdown, focus sequentially lands on `Capture Note` > `Link Only` > `Link & Create` > `Settings Cog`.

### Configuration Modal
*   **Two-Tier Settings Design:** 
    *   **Primary Menu:** Shows global sizing variables, property injection preferences, and a clean index of Note Types displaying the associated Lucide Icon, Title, and a `Delete` button. A `Save Settings` CTA resides prominently next to the main header, mirroring the bottom footer.
    *   **Secondary Note Edit Menu:** Opened via the `Edit` button on the primary menu list. This manages individual Note Type parameters. Text inputs for Folder and Templates hook into custom Suggest objects extending `AbstractInputSuggest`.

## 4. Execution Pathway (`start()`)

### Target Resolution & Link Generation
1.  On execution, checks for active text element selections containing WikiLinks.
2.  Triggers `openCaptureModal()`.
3.  Once completed, resolves the required folder routes and constructs the unified target filename.
4.  Generates a raw string `[[Target File]]`.

### File Generation & Templater Injection
*   Checks if the target file exists.
*   If missing, utilizes `app.vault.create` passing the base template configuration. 
*   **Templater Trigger Catching:** Pauses 1000ms. Loads the new file temporarily in a background pane. Forces an explicit `app.commands.executeCommandById("templater-obsidian:replace-in-file-templater")` trigger to ensure template variables unfold, then suspends execution for 1000ms for I/O sync.
*   **Property Injection:** Modifies the compiled markdown document, appending the configured `Note type` key inside either YAML frontmatter or as a Dataview double-colon field (`Note type:: #value`).

### Dual-Note Injection Mechanism
The script assembles dynamic "New Section" labels contextualizing the timestamp and originating location. (e.g., `2026-05-27 Wednesday, Initiator Page`).

**For Visual Formats:**
1.  Calculates lowest-bound coordinate limits (`boundingbox + 100px gap`) on the target Note B.
2.  Creates a designated marker Frame at `(X, Y)` named with the raw section title.
3.  Reactivates Note A's canvas pane.
4.  Calculates local coordinates below the selected text source.
5.  Creates an Image fragment pointing to Note B: `![[Note B#^frame=FRAME_ID]]`.
6.  Injects the selected action verb: `element.link = (discussing:: [[Note B#^frame=FRAME_ID]])`.

**For Markdown Formats:**
1.  Modifies Note B's markdown structure. Safely splits the document based on `# Notes` and `# Excalidraw Data`.
2.  If the Excalidraw JSON payload is commented out via `%%\n# Excalidraw Data`, an empty `# \n\n` section is injected immediately above it to prevent the interactive embeddable from rendering the commented blocks visually.
3.  Generates a second-level header `## [[DNP]], [[Initiator]]` placing it cleanly inside `# Notes`.
4.  Creates an Interactive Markdown Embeddable element on Note B mapping to its own header segment.
5.  Reactivates Note A.
6.  Generates the mirrored Embeddable or Static Image referencing the markdown section, embedding the same Ontology Link metadata to tie the task structures together.
7.  Switches focus permanently to Note B and automatically executes `ea.viewZoomToElements()` centering the screen precisely on the newly built container.

# Comic Book Callouts & Speech Bubbles Generator
A highly modular, versatile Excalidraw Automate Sidepanel script for creating comic-book style speech bubbles, thought clouds, screams, narrative boxes, and radiant halo callouts.

Features:
- Sidepanel UX: Preserves user input and scroll state while hopping across multiple Excalidraw canvas views.
- Live SVG Preview: Real-time rendered snapshot constrained safely to preview container bounds.
- Context-Aware Editing: Seamlessly detects, imports, and updates existing canvas callouts without background insertion bugs.
- Rich Base Shapes: Oval, Box (with corner roundness), Cloud, Spiky/Scream, Heart, Polygon (with rotation), and Ribbon.
- Advanced Halo Generator: Multi-layered radiating sun rays, dots, continuous rings, and dashed rings with customizable spacing, density, variance, and dynamic mathematical thickness/gap growth patterns.
- Action Explosion Spikes: Overlay deterministic pseudo-random spikes onto compatible base geometries.
- Versatile Tails/Stems: Splicing stems (V-Shape, Curvy Swoop, Lightning Zig-Zag) and detached stems (Diminishing Thought Bubbles, Multi-segment Lines) with adjustable perimeter positioning and bend deflection.
- Granular Typography: Wrap width, internal padding, font size profiles, and extended font family dropdown support (Excalifont, Lilita One, Comic Shanns, Nunito, Assistant, etc.).
- Deep Appearance & Color Sync: Hachure/Zigzag/Cross-hatch fills, sloppiness profiles, stroke sharpness, and triple-synced color pickers (Swatch popover + Native picker + Hex text field).
- Safe Preset Management: Save, load, and create custom user callout styles (text automatically excluded to prevent dialogue overwrites).

### Architecture Notes for Future Extensibility:
1. **State Management**: The `state` object holds all active parameters. Adding a new parameter means adding its default to `DEFAULT_STATE`, creating a UI control for it, and utilizing it in `buildElements()`.
   - When saving metadata to Excalidraw's `customData`, `state` is deep-cloned to prevent shared reference mutations across multiple inserted callouts.
   - Missing properties on legacy presets or older canvas elements are safely healed by merging incoming objects against a deep copy of `DEFAULT_STATE`.
2. **Shape Generation Pipeline**:
   - `generateSmoothBaseShape(rx, ry)`: Creates the smooth closed perimeter of the base shape.
   - `injectSpikes(smoothPts)`: Splicing step that injects explosion spikes into compatible perimeters.
   - `generateHalo(smoothPts, spikedPts)`: Computes radial normals to generate non-intersecting background halo elements while skipping the stem gap region.
   - `injectStem(basePts, rx, ry)`: Splices or attaches the tail/stem into the main perimeter.
   - `buildElements(isFinal)`: Constructs the workbench elements (Halo + Polygon + Extras + Text) and attaches deep-copied metadata.
   - `renderPreview(previewContainer)`: Generates a size-constrained SVG snapshot.
3. **UI & Event Handling**:
   - DOM elements (like action buttons and text areas) are preserved and updated during `onFocus` rather than destroyed to prevent interaction bugs (e.g., requiring double-clicks to insert).
   - Action buttons dynamically enable/disable based on whether the active workspace leaf matches the script's target Excalidraw view.

This script darkens the background color of the selected element by 2% at a time. 

You can use this script several times until you are satisfied. It is recommended to set a shortcut key for this script so that you can quickly try to DARKEN and LIGHTEN the color effect.

In contrast to the `Modify background color opacity` script, the advantage is that the background color of the element is not affected by the canvas color, and the color value does not appear in a strange rgba() form.

The color conversion method was copied from [color-convert](https://github.com/Qix-/color-convert).

Select some elements in the scene. The script will take these elements and move them into a new Excalidraw file, and open that file. The selected elements will also be replaced in your original drawing with the embedded Excalidraw file (the one that was just created). You will be prompted for the file name of the new deconstructed image. The script is useful if you want to break a larger drawing into smaller reusable parts that you want to reference in multiple drawings.

This script arranges selected elements and groups with a fixed inner distance.

Tips: You can use the `Box Selected Elements` and `Dimensions` scripts to create rectangles of the desired size, then use the `Change shape of selected elements` script to convert the rectangles to ellipses, and then use the `Fixed inner distance` script regains a desired inner distance.

Inspiration: #394

## Folder Note Core - Make Current Drawing a Folder.md
<!-- Source: ea-scripts/Folder Note Core - Make Current Drawing a Folder.md -->

/*
This script adds the `Folder Note Core: Make current document folder note` function to Excalidraw drawings. Running this script will convert the active Excalidraw drawing into a folder note. If you already have embedded images in your drawing, those attachments will not be moved when the folder note is created. You need to take care of those attachments separately, or convert the drawing to a folder note prior to adding the attachments. The script requires the [Folder Note Core](https://github.com/aidenlx/folder-note-core) plugin.

## Full-Year Calendar Generator.md
<!-- Source: ea-scripts/Full-Year Calendar Generator.md -->

/*

This script generates a complete calendar for a specified year, visually distinguishing weekends from weekdays through color coding.

![](https://raw.githubusercontent.com/zsviczian/obsidian-excalidraw-plugin/master/images/scripts-full-year-calendar-exemple.excalidraw.png)

## Customizable Colors

You can personalize the calendar’s appearance by defining your own colors:

1. Create two rectangles in your design.
2. Select both rectangles before running the script:
	• The **fill and stroke colors of the first rectangle** will be applied to weekdays.
	• The **fill and stroke colors of the second rectangle** will be used for weekends.

If no rectangle are selected, the default color schema will be used (white and purple).

## Golden Ratio.md
<!-- Source: ea-scripts/Golden Ratio.md -->

/*
The script performs two different functions depending on the elements selected in the view.
1) In case you select text elements, the script will cycle through a set of font scales. First the 2 larger fonts following the Fibonacci sequence (fontsize * φ; fonsize * φ^2), then the 2 smaller fonts (fontsize / φ; fontsize / φ^2), finally the original size, followed again by the 2 larger fonts. If you wait 2 seconds, the sequence clears and starts from which ever font size you are on. So if you want the 3rd larges font, then toggle twice, wait 2 sec, then toggle again.
2) In case you select a single rectangle, the script will open the "Golden Grid", "Golden Spiral" window, where you can set up the type of grid or spiral you want to insert into the document.

/*
 * ==============================================================================
 * Icon Library Sidepanel
 * ==============================================================================
 * Purpose:
 * Provides a responsive, lazily loaded icon library implemented natively as an
 * Excalidraw Automate Sidepanel. It allows users to search, keyboard-navigate,
 * and seamlessly insert items (SVG exports of Excalidraw files or raster images)
 * into Excalidraw or MindMap Builder.
 *
 * Key Features:
 * - Configurable regex-based file filtering and keyword extraction.
 * - Auto-generation of SVG thumbnails for Excalidraw files.
 * - Lazy-loaded grid with responsive thumbnail sizing via a vertical slider popover.
 * - Theme-aware thumbnail backgrounds (configurable for Light and Dark modes).
 * - Keyboard accessibility for navigation and insertion.
 * - MindMap Builder integration.
 *
 * High-Level Logic / Architecture:
 * - Global Constants & Strings: Centralized at the top for easy localization and tuning.
 * - Main entry point (`main()`) handles singleton tab creation and state management.
 * - Strictly modular UI rendering functions separate layout assembly from business logic.
 * - Lazy loading is managed via an IntersectionObserver to conserve memory.
 * - A custom settings modal handles configuration and includes a live regex tester.

1. Ask the user questions to understand what icons or files they want to include in their library.

## Image Occlusion.md
<!-- Source: ea-scripts/Image Occlusion.md -->

/*
# Image Occlusion for Excalidraw

This script creates image occlusion cards similar to Anki's Image Occlusion Enhanced plugin.

## Usage:
1. Insert an image into Excalidraw
2. Draw rectangles or ellipses over areas you want to occlude
3. Select the image and all shapes you want to use as masks
4. Run this script
5. Choose occlusion mode:
   - ⭐⠀      Add Cards:    Hide One, Guess One: Creates cards where only one shape is hidden at a time
   - ⭐⭐     Add Cards:    Hide All, Guess One: Creates cards where all shapes are hidden except one
   - 🗑️⠀      Delete Cards: Delete old cards (add DELETE marker): Marks all existing cards for deletion by adding DELETE marker
   - 🗑️💥     Delete Cards: Delete old cards file and related images (Be Cautious!! Physical Delection): Permanently deletes all related card files and images

The script will generate masked versions of the image and save them locally.

## Invert colors.md

/*
![](https://raw.githubusercontent.com/zsviczian/obsidian-excalidraw-plugin/master/images/scripts-invert-colors.jpg)

  

The script inverts the colors on the canvas including the color palette in Element Properties.

This script inverts all the colors in the current Excalidraw drawing. It applies the inversion to:
1. The stroke and background colors of every element on the canvas.
2. The main canvas background color.
3. All colors within the user's custom color palette, handling all possible configurations (simple arrays, nested arrays, and objects).
4. The currently selected stroke and background colors in the UI.
 
A default color palette is defined to use as a fallback if the current drawing's palette is missing or empty. // This is based on the standard Excalidraw palette from version [1.6.8.](https://github.com/zsviczian/obsidian-excalidraw-plugin/releases/tag/1.6.8)

You'll find a detailed description of the color palette data structure on the [Excalidraw-Obsidian Wiki](https://excalidraw-obsidian.online/wiki/color-palette)

This script lightens the background color of the selected element by 2% at a time. 

You can use this script several times until you are satisfied. It is recommended to set a shortcut key for this script so that you can quickly try to DARKEN and LIGHTEN the color effect.

In contrast to the `Modify background color opacity` script, the advantage is that the background color of the element is not affected by the canvas color, and the color value does not appear in a strange rgba() form.

The color conversion method was copied from [color-convert](https://github.com/Qix-/color-convert).

## Linear Calendar Generator.md
<!-- Source: ea-scripts/Linear Calendar Generator.md -->

/*

This script generates a linear (horizontal) calendar for a specified year, with days flowing left to right and months as rows.

![300](https://raw.githubusercontent.com/zsviczian/obsidian-excalidraw-plugin/master/images/scripts-Linear-Calendar-Generator.jpg)

## Features
- Horizontal timeline layout with days of the week as columns
- Month names displayed on both left and right sides
- Weekend days (Saturday & Sunday) highlighted
- Day-of-week headers at top and bottom

## Customizable Colors

You can personalize the calendar's appearance by defining your own colors:

1. Create two rectangles in your design.
2. Select both rectangles before running the script:
	• The **fill and stroke colors of the first rectangle** will be applied to weekdays.
	• The **fill and stroke colors of the second rectangle** will be used for weekends.

If no rectangles are selected, the default color schema will be used (white and light blue-gray for weekends).

/**
# Mind Map Builder: Technical Specification & User Guide

## Overview
**Mind Map Builder** transforms the Obsidian-Excalidraw canvas into a rapid brainstorming environment, allowing users to build complex, structured, and visually organized mind maps using primarily keyboard shortcuts.

The script balances **automation** (auto-layout, recursive grouping, and contrast-aware coloring) with **explicit flexibility** (node pinning and redirection logic), ensuring that the mind map stays organized even as it grows to hundreds of nodes. It leverages the Excalidraw Sidepanel API to provide a persistent control interface utilizing the Obsidian sidepanel, that can also be undocked into a floating modal.

## Technical notes

### Sidepanel & Docking
- **Persistent UI**: The script utilizes `ea.createSidepanelTab` to maintain state and controls alongside the drawing canvas.
- **Floating Mode**: The UI can be "undocked" (Shift+Enter) into a `FloatingModal` for a focus-mode experience or to move controls closer to the active drawing area on large screens.

### Map-Specific Persistence (customData)
The script uses `ea.addAppendUpdateCustomData` to store state on elements:
- `growthMode`: Stored on the Root node (Radial, Left, or Right).
- `autoLayoutDisabled`: Stored on the Root node to pause layout engine for specific maps (toggle from UI).
- `arrowType`, `fontsizeScale`, `multicolor`, `boxChildren`, `roundedCorners`, `maxWrapWidth`, `isSolidArrow`, `centerText`: Stored on the Root node to persist display preferences per map.
- `isPinned`: Stored on individual nodes (boolean) to bypass the layout engine.
- `isBranch`: Stored on arrows (boolean) to distinguish Mind Map connectors from standard annotations.
- `mindmapOrder`: Stored on nodes (number) to maintain manual sort order of siblings.
- `mindmapNew`: Stored on nodes (boolean) to tag freshly added items so new siblings append after existing order; cleared after layout.
- `isFolded`: Stored on nodes (boolean) to collapse a branch and hide its descendants.
- `foldIndicatorId`: Stored on nodes to track the ephemeral "…" indicator element that signals a folded branch.
- `foldState`: Stored on nodes and branch arrows to cache their opacity/lock state while hidden so it can be restored when unfolded.
- `boundaryId`: Stored on nodes to track the ID of the boundary element (a closed polygon line) that visually encompasses the node's subtree.
- `isBoundary`: Stored on the line polygon to mark it is a boundary for a node.

### The "mindmapNew" Tag & Order Stability
When a Level 1 node is created, it is temporarily tagged with `mindmapNew: true`. The layout engine uses this to separate "Existing" nodes from "New" nodes. Existing nodes are sorted by their `mindmapOrder` (or visual angle/Y-position if order is missing), while new nodes are appended to the end. This prevents new additions from scrambling the visual order of existing branches.

### Sidepanel Lifecycle Management
The script implements `SidepanelTab` hooks (`onFocus`, `onClose`, `onWindowMigrated`) to handle:
- **Context Switching**: Rebinding event listeners when the user switches between multiple Excalidraw views.
- **Window Migration**: Re-attaching keyboard handlers when the sidepanel moves between the main window and a popout window.
- **Auto-Docking**: Ensuring floating modals are docked back to the sidepanel when the view closes to prevent UI orphans.

### Recursive Grouping
When enabled, the script groups elements from the "leaves" upward. A leaf node is grouped with its parent and the connecting arrow. That group is then nested into the grandparent's group. The **Root Exception**: The root node is never part of an L1 group, allowing users to move the central idea or detach whole branches easily.

### Smart Decoration Scaling (Edge Anchoring)
When nodes resize (e.g. text edit), the script intelligently re-positions grouped elements:
- **Inside Elements**: Scale relative to the center (e.g. text inside a box).
- **Outside Elements**: Anchor to the nearest edge (e.g. icons above a node) to preserve visual gaps, preventing them from "flying away" during expansion.

### Copy/Paste & Cross-linking
- **Hierarchy**: Markdown lists are parsed into the mind map structure.
- **Cross-links**: The script preserves non-structural connections by generating internal block references (`^blockId`) and valid wikilinks (`[[#^blockId]]`) when copying branches to markdown.

### Link suggester keydown events (Enter, Escape)
- **Key-safe integration**: The suggester implements the `KeyBlocker` interface so the script's own key handlers pause while the suggester is active, preventing shortcut collisions during link insertion.

format **the left to right** mind map

![](https://raw.githubusercontent.com/zsviczian/obsidian-excalidraw-plugin/master/images/scripts-mindmap-format-1.png)

# tree

Mind map is actually a tree, so you must have a **root node**. The script will determine **the leftmost element** of the selected element as the root element (node is excalidraw element, e.g. rectangle, diamond, ellipse, text, image, but it can't be arrow, line, freedraw, **group**)

The element connecting node and node must be an **arrow** and  have the correct direction, e.g. **parent node -> children node**

# sort

The order of nodes in the Y axis or vertical direction is determined by **the creation time** of the arrow connecting it

![](https://raw.githubusercontent.com/zsviczian/obsidian-excalidraw-plugin/master/images/scripts-mindmap-format-2.png)

So if you want to readjust the order, you can **delete arrows and reconnect them**

# setting

Script provides options to adjust the style of mind map, The option is at the bottom of the option of the exalidraw plugin(e.g. Settings -> Community plugins -> Excalidraw -> drag to bottom)

# problem

1. since the start bingding and end bingding of the arrow are easily disconnected from the node, so if there are unformatted parts, please **check the connection** and use the script to **reformat**

## Modify background color opacity.md
<!-- Source: ea-scripts/Modify background color opacity.md -->

/*
![](https://raw.githubusercontent.com/zsviczian/obsidian-excalidraw-plugin/master/images/scripts-download-raw.jpg)

Download this file and save to your Obsidian Vault including the first line, or open it in "Raw" and copy the entire contents to Obsidian.

![](https://raw.githubusercontent.com/zsviczian/obsidian-excalidraw-plugin/master/images/scripts-modify-background-color-opacity.png)

This script changes the opacity of the background color of the selected boxes.

The default background color in Excalidraw is so dark that the text is hard to read. You can lighten the color a bit by setting transparency. And you can tweak the transparency over and over again until you're happy with it.

Although excalidraw has the opacity option in its native property Settings, it also changes the transparency of the border. Use this script to change only the opacity of the background color without affecting the border.

## Normalize Selected Arrows.md

This script will reset the start and end positions of the selected arrows. The arrow will point to the center of the connected box and will have a gap of 8px from the box.

Tips: If you are drawing a flowchart, you can use `Normalize Selected Arrows` script to correct the position of the start and end points of the arrows, then use `Elbow connectors` script, and you will get the perfect connecting line!

Converts selected freedraw lines such that pencil pressure will decrease from maximum to minimum from the beginning of the line to its end. The resulting line is placed at the back of the layers, under all other items. Helpful when drawing organic mindmaps.

This is the old script from this [video](https://youtu.be/JMcNDdj_lPs?t=479). Since it's release this has been superseded by custom pens that you can enable in plugin settings. For more on custom pens, watch [this](https://youtu.be/OjNhjaH2KjI) 

The benefit of the approach in this implementation of custom pens is that it will look the same on excalidraw.com when you copy your drawing over for sharing with non-Obsidian users. Otherwise custom pens are faster to use and much more configurable.

```javascript
*/
let elements = ea.getViewSelectedElements().filter((el)=>["freedraw","line","arrow"].includes(el.type));
if(elements.length === 0) {
  elements = ea.getViewSelectedElements();
  const len = elements.length;
  if(len === 0 || ["freedraw","line","arrow"].includes(elements[len].type)) {
    return;
  }
  elements = [elements[len]];
} 

ea.copyViewElementsToEAforEditing(elements);

ea.getElements().forEach((el)=>{
  el.simulatePressure = false;
  el.type = "freedraw";
  el.pressures = [];
  const len = el.points.length;
  for(i=0;i<len;i++)
    el.pressures.push((len-i)/len);

## Palm Guard.md
<!-- Source: ea-scripts/Palm Guard.md -->

/*
Palm Guard: A mobile-friendly drawing mode for Excalidraw that prevents accidental palm touches by hiding UI controls and entering fullscreen mode. Perfect for drawing with a stylus on tablets.

Features:
- Enters fullscreen to maximize drawing space (configurable in plugin script settings)
- Hides all UI controls to prevent accidental taps
- Provides a minimal floating toolbar with toggle visibility button
- Enables a completely distraction-free canvas even on desktop devices by hiding the main toolbar and all chrome while keeping a tiny movable toggle control (addresses immersive canvas / beyond Zen Mode request)
- Draggable toolbar can be positioned anywhere on screen
- Exit Palm Guard mode with a single tap
- Press the hotkey you configured for this script in Obsidian's Hotkey settings (e.g., ALT+X) to toggle UI visibility; if no hotkey is set, use the on-screen toggle button.

**Easily split your Excalidraw drawing into printable pages!**

If you find this script helpful, consider [buying me a coffee](https://ko-fi.com/zsolt). Thank you.

---

### How it works

- **Define Pages:** Use frames to mark out each page area in your drawing. You can create the first frame with this script (choose a standard size or orientation), or draw your own frame for a custom page size.
- **Add More Pages:** Select a frame, then use the arrow buttons to add new frames next to it. All new frames will match the size of the selected one.
- **Rename Frames:** You can rename frames as you like. When exporting to PDF, pages will be ordered alphabetically by frame name.

---

### Important Notes

- **Same Size & Orientation:** All frames must have the same size and orientation (e.g., all A4 Portrait) to export to PDF. Excalidraw currently does not support PDFs with different-sized pages.
- **Custom Sizes:** If you draw your own frame, the PDF will use that exact size—great for custom page layouts!
- **Margins:** If you set a margin, the page size stays the same, but your content will shrink to fit inside the printable area.
- **No Frame Borders/Titles in Print:** Frame borders and frame titles will *not* appear in the PDF.
- **No Frame Clipping:** The script disables frame clipping for this drawing.
- **Templates:** You can save a template document with prearranged frames (even locked ones) for reuse.
- **Lock Frames:** Frames only define print areas—they don't "contain" elements. Locking frames is recommended to prevent accidental movement.
- **Outside Content:** Anything outside the frames will *not* appear in the PDF.

---

### Printing

- **Export to PDF:** Click the printer button to export each frame as a separate page in a PDF.
- **Order:** Pages are exported in alphabetical order of frame names.

---

### Settings

You can also access script settings at the bottom of Excalidraw Plugin settings. The script stores your preferences for:
- Locking new frames after creation
- Zooming to new frames
- Closing the dialog after adding a frame
- Default page size and orientation
- Print margin

# Excalidraw Script Engine scripts library

【English | [简体中文](../docs/zh-cn/ea-scripts/README.md)】

Click to watch the intro video:

[![Script Engine](https://user-images.githubusercontent.com/14358394/145684531-8d9c2992-59ac-4ebc-804a-4cce1777ded2.jpg)](https://youtu.be/hePJcObHIso)

> **Warning**
> There is an easier way to install/manage scripts than what is shown in this video

See the [Excalidraw Script Engine](https://zsviczian.github.io/obsidian-excalidraw-plugin/ExcalidrawScriptsEngine.html) documentation for more details.

## How to install scripts into your Obsidian Vault
To install one of the built-in scripts:
- Open up an excalidraw drawing in Obsidian
- In the pane dropdown menu select "Install or update Excalidraw Scripts"
- Click on one of the available scripts
- Click on "Install this script" (note if the script is already installed you will instead see an option to update it)
- Restart Obsidian so the script will be picked up

Note: By default this will install the script into your vault in the `Excalidraw/Scripts/Downloaded` folder

<details><summary>Manual installation of scripts</summary>

Open the script you are interested in and save it to your Obsidian Vault including the first line `/*`, or open it in "Raw" and copy the entire contents to Obsidian.

## List of available scripts
|Title|Description|Icon|Contributor|
|----|----|----|----|
|[Add Connector Point](Add%20Connector%20Point.md)|This script will add a small circle to the top left of each text element in the selection and add the text and the "bullet point" into a group.|![](https://raw.githubusercontent.com/zsviczian/obsidian-excalidraw-plugin/master/images/scripts-bullet-point.jpg)|[@zsviczian](https://github.com/zsviczian)|
|[Add Link to Existing File and Open](Add%20Link%20to%20Existing%20File%20and%20Open.md)|Prompts for a file from the vault. Adds a link to the selected element pointing to the selected file. You can control in settings to open the file in the current active pane or an adjacent pane.|![](https://raw.githubusercontent.com/zsviczian/obsidian-excalidraw-plugin/master/images/scripts-add-link-and-open.jpg)|[@zsviczian](https://github.com/zsviczian)|
|[Add Link to New Page and Open](Add%20Link%20and%20Open%20Page.md)|Prompts for filename. Offers option to create and open a new Markdown or Excalidraw document. Adds link pointing to the new file, to the selected objects in the drawing. You can control in settings to open the file in the current active pane or an adjacent pane.|![](https://raw.githubusercontent.com/zsviczian/obsidian-excalidraw-plugin/master/images/scripts-add-link-to-new-page-and-pen.jpg)|[@zsviczian](https://github.com/zsviczian)|
|[Add Next Step in Process](Add%20Link%20to%20New%20Page%20and%20Open.md)|This script will prompt you for the title of the process step, then will create a stick note with the text. If an element is selected then the script will connect this new step with an arrow to the previous step (the selected element).

Scribble Helper can improve handwriting and add links. It lets you create and edit text elements, including wrapped text and sticky notes, by double-tapping on the canvas. When you run the script, it creates an event handler that will activate the editor when you double-tap. If you select a text element on the canvas before running the script, it will open the editor for that element. If you use a pen, you can set it up to only activate Scribble Helper when you double-tap with the pen. The event handler is removed when you run the script a second time or switch to a different tab.

Use this script to set the background color of unclosed (i.e. open) line, arrow and freedraw objects by creating a clone of the object. The script will set the stroke color of the clone to transparent and will add a straight line to close the object. Use settings to define the default background color, the fill style, and the strokeWidth of the clone. By default the clone will be grouped with the original object, you can disable this also in settings.

## Shade Master.md
<!-- Source: ea-scripts/Shade Master.md -->

/*
This is an experimental script. If you find bugs, please consider debugging yourself then submitting a PR on github with the fix, instead of raising an issue. Thank you!

This script modifies the color lightness/hue/saturation/transparency of selected Excalidraw elements and  SVG and nested Excalidraw drawings. Select eligible elements in the scene, then run the script.

- The color of Excalidraw elements (lines, ellipses, rectangles, etc.) will be changed by the script.
- The color of SVG elements and nested Excalidraw drawings will only be mapped. When mapping colors, the original image remains unchanged, only a mapping table is created and the image is recolored during rendering of your Excalidraw screen. In case you want to make manual changes you can also edit the mapping in Markdown View Mode under `## Embedded Files`

If you select only a single SVG or nested Excalidraw element, then the script offers an additional feature. You can map colors one by one in the image. 
```js
*/

const HELP_TEXT = `
- Select SVG images, nested Excalidraw drawings and/or regular Excalidraw elements
- For a single selected image, you can map colors individually in the color mapping section
- For Excalidraw elements: stroke and background colors are modified permanently
- For SVG/nested drawings: original files stay unchanged, color mapping is stored under \`## Embedded Files\`
- Using color maps helps maintain links between drawings while allowing different color themes
- Sliders work on relative scale - the amount of change is applied to current values
- Unlike Excalidraw's opacity setting which affects the whole element:
    - Shade Master can set different opacity for stroke vs background
    - **Note:** SVG/nested drawing colors are mapped at color name level, thus "black" is different from "#000000"
    - Additionally if the same color is used as fill and stroke the color can only be mapped once
- This is an experimental script - contributions welcome on GitHub via PRs

# About the slideshow script
The script will convert your drawing into a slideshow presentation.
![Slideshow 3.0](https://www.youtube.com/JwgtCrIVeEU)

![](https://raw.githubusercontent.com/zsviczian/obsidian-excalidraw-plugin/master/images/scripts-slideshow-2.jpg)
## Presentation options
- If you select an arrow or line element, the script will use that as the presentation path.
- If you select nothing, but the file has a hidden presentation path, the script will use that for determining the slide sequence.
- If there are frames, the script will use the frames for the presentation. Frames are played in alphabetical order of their titles.
# Keyboard shortcuts and modifier keys
**Forward**: Arrow Down, Arrow Right, or SPACE
**Backward**: Arrow Up, Arrow Left
**Finish presentation**: Backspace, ESC (I had issues with ESC not working in full screen presentation mode on Mac)

**Run presentation in a window**: Hold down the ALT/OPT modifier key when clicking the presentation script button
**Continue presentation**: Hold down SHIFT when clicking the presentation script button. (The feature also works in combination with the ALT/OPT modifier to start the presentation in a window). The feature will only resume while you are within the same Obsidian session (i.e. if you restart Obsidian, slideshow will no longer remember where you were). I have two use cases in mind for this feature: 
1) When you are designing your presentation you may want to test how a slide looks. Using this feature you can get back to where you left off by starting the presentation with SHIFT.
2) During presentation you may want to exit presentation mode to show something additional to your audience. You stop the presentation, show the additional thing you wanted, now you want to continue from where you left off. Hold down SHIFT when clicking the slideshow button.

## Split Ellipse.md
<!-- Source: ea-scripts/Split Ellipse.md -->

/*

This script splits an ellipse at any point where a line intersects it. If no lines are selected, it will use every line that intersects the ellipse. Otherwise, it will only use the selected lines. If there is no intersecting line, the ellipse will be converted into a line object. 
There is also the option to close the object along the cut, which will close the cut in the shape of the line.

![](https://raw.githubusercontent.com/zsviczian/obsidian-excalidraw-plugin/master/images/scripts-splitEllipse-demo2.png)
Tip: To use an ellipse as the cutting object, you first have to use this script on it, since it will convert the ellipse into a line.


See documentation for more details:

If you copy a color string on the clipboard before running the script, the script will use that color instead of the inverted color.

## Text to Path.md
<!-- Source: ea-scripts/Text to Path.md -->

/*
![](https://raw.githubusercontent.com/zsviczian/obsidian-excalidraw-plugin/master/images/scripts-text-to-path.jpg)

This script allows you to fit a text element along a selected path: line, arrow, freedraw, ellipse, rectangle, or diamond. You can select either a path or a text element, or both:

- If only a path is selected, you will be prompted to provide the text.
- If only a text element is selected and it was previously fitted to a path, the script will use the original path if it is still present in the scene.
- If both a text and a path are selected, the script will fit the text to the selected path.

If the path is a perfect circle, you will be prompted to choose whether to fit the text above or below the circle.

After fitting, the text will no longer be editable as a standard text element, but you'll be able to edit it with this script. Text on path cannot function as a markdown link. Emojis are not supported.
