Excalidraw Icon Library

readme.md

Please check out my YouTube video Create a library of your downloaded icons with Excalidraw Automate in Obsidian, it provides a detailed walkthrough of this code.

To save these files into your Vault, either download them, or switch to RAW mode to copy/paste them into your Obsidian Vault. You may need to use CTRL+SHIFT+V to paste.

Icons created by the script are locked in the scene, you can right click them to select and copy them. Locking the eleemnts avoids the need for switching to view mode and ensures the file does not get accidently modified, thus the images in the image library are not actually saved to the image library causing unwanted links in your Vault.

Advanced usage

I use the script with LOCK_ICONS=true; because in this case I won't accidently move items in the image library causing it to save the icons in the file and creating unwanted links in Excalibrain pointing back to the icon library. If you lock icons then you need to right click the selected icon to copy it to the clipboard, however, when you paste the icon to your drawing it will be locked - which is not convenient. For this reason I've also configured an onPaste event handler via the Excalidraw startup script. This automatically unlocks all elements on paste.

ea.onPasteHook = (data) => {
  if(data?.payload?.elements) {
    data.payload.elements.filter(el=>el.locked).forEach(el=>{el.locked = false;});
  }
};

Hi! Any way to automatically set "invert colors"?

I had the same issue as LEEJOOPIL.
Added the script to a new installation with only the bare minimum of community plugins.
The error is "Uncaught SyntaxError: Illegal return statement" and points to this code: if(f!==ea.targetView.file && ea.targetView?.getViewType?.()!=="excalidraw") return;
Removing that line doesn't help either.

This sounds like a plugin is automatically modifying files, e.g. adding some metadata, etc, that creates a syntax error.
Disable other plugins. Delete and re-add the script. Is the error still happening?

Please share the output of command palette "Debug info" so I can see your definition of bare minimum.

Debug Info:
SYSTEM INFO:
Obsidian version: v1.5.12
Installer version: v1.5.3
Operating system: Windows 10 Home 10.0.22631
Login status: not logged in
Insider build toggle: off
Live preview: on
Base theme: dark
Community theme: AnuPpuccin v1.4.5
Snippets enabled: 3
Restricted mode: off
Plugins installed: 1
Plugins enabled: 1
1: Excalidraw v2.2.4

RECOMMENDATIONS:
Custom theme and snippets: for cosmetic issues, please first try updating your theme and disabling your snippets. If still not fixed, please try to make the issue happen in the Sandbox Vault or disable community theme and snippets.
Community plugins: for bugs, please first try updating all your plugins to latest. If still not fixed, please try to make the issue happen in the Sandbox Vault or disable community plugins.

I deleted all plugins except Excalidraw.
Deleted the Icon Library script and Icon Library.md from the vault.
Copied the raw Icon Library script.
Created a new empty drawing
opened the Console
added ea=excalidraw.automate
ea.setview('first')
pasted in the icon library script
and still the same error.
