ios – Definitive method to allow ESC-key-like performance for Obsidian on iPhone

Has anybody supplied an excellent resolution to the dearth of an escape key on iPhone but, for vim mode? I really feel like this wants a definitive resolution, and I’d be prepared to work on it if no one has, but.

Not an exterior keyboard. Only a plugin that provides a great way to enter the escape character, like a particular button above the keyboard, or a particular character sequence that will get remapped to the ESC key code, and many others.

What technique can be the most effective resolution for implementing this, if writing an Obsidian plugin? Like, essentially the most pure method to work throughout the confines of iOS, and never a type of awkward workaround.

From Claude 3.5 Sonnet, to present concepts and attempt to get the ball rolling:

1. Particular Character Sequence Remapping

Listening for a particular character sequence and remapping it to the ESC key.

1. In your major plugin class, add an occasion listener for the 'keydown' occasion:

import { Plugin, EditorView } from 'obsidian';

export default class EscKeyPlugin extends Plugin {
  personal lastKeys: string[] = [];
  personal escSequence=";;"; // Configurable

  async onload() {
    this.registerDomEvent(doc, 'keydown', (occasion: KeyboardEvent) => {
      this.handleKeyPress(occasion);
    });
  }

  personal handleKeyPress(occasion: KeyboardEvent) {
    this.lastKeys.push(occasion.key);
    if (this.lastKeys.size > this.escSequence.size) {
      this.lastKeys.shift();
    }

    if (this.lastKeys.be part of('') === this.escSequence) {
      this.triggerEsc();
      occasion.preventDefault();
      this.lastKeys = [];
    }
  }

  personal triggerEsc() {
    const activeLeaf = this.app.workspace.activeLeaf;
    if (activeLeaf && activeLeaf.view instanceof EditorView) {
      const cm = activeLeaf.view.editor.cm;
      cm.triggerOnKeyDown(new KeyboardEvent('keydown', { key: 'Escape' }));
    }
  }
}

• Make the escape sequence configurable within the plugin settings.
• Think about including a small delay to differentiate between intentional sequence enter and common typing.

2. Customized Button Overlay

Add a floating button that triggers the ESC key performance when tapped.

1. Create the button factor and add it to the DOM:

import { Plugin, EditorView } from 'obsidian';

export default class EscKeyPlugin extends Plugin {
  personal escButton: HTMLElement;

  async onload() {
    this.escButton = this.createEscButton();
    doc.physique.appendChild(this.escButton);
  }

  onunload() {
    this.escButton.take away();
  }

  personal createEscButton(): HTMLElement {
    const button = doc.createElement('button');
    button.setText('ESC');
    button.addClass('esc-button');
    button.fashion.place = 'mounted';
    button.fashion.backside = '20px';
    button.fashion.proper="20px";
    button.fashion.zIndex = '1000';
    
    button.addEventListener('click on', () => {
      this.triggerEsc();
    });

    return button;
  }

  personal triggerEsc() {
    // Similar implementation as within the earlier instance
  }
}

2. Add CSS to fashion the button:

.esc-button {
  background-color: #202020;
  colour: white;
  border: none;
  border-radius: 50%;
  width: 50px;
  top: 50px;
  font-size: 14px;
  box-shadow: 0 2px 5px rgba(0,0,0,0.2);
}

• Make the button’s place and look customizable.
• Think about including an choice to cover/present the button with a gesture.

3. Gesture Recognition

Implement a customized gesture to set off the ESC key performance.

1. Add a contact occasion listener to acknowledge a particular gesture:

import { Plugin, EditorView } from 'obsidian';

export default class EscKeyPlugin extends Plugin {
  personal touchStartX: quantity = 0;
  personal touchStartY: quantity = 0;

  async onload() {
    this.registerDomEvent(doc, 'touchstart', (e: TouchEvent) => {
      this.touchStartX = e.touches[0].clientX;
      this.touchStartY = e.touches[0].clientY;
    });

    this.registerDomEvent(doc, 'touchend', (e: TouchEvent) => {
      const touchEndX = e.changedTouches[0].clientX;
      const touchEndY = e.changedTouches[0].clientY;
      
      const deltaX = touchEndX - this.touchStartX;
      const deltaY = touchEndY - this.touchStartY;
      
      if (Math.abs(deltaX) < 10 && deltaY < -50) {
        // Swipe up detected
        this.triggerEsc();
      }
    });
  }

  personal triggerEsc() {
    // Similar implementation as within the earlier examples
  }
}

• Make the gesture customizable (e.g., swipe path, distance threshold).
• Think about using a library like Hammer.js for extra advanced gesture recognition.

Notes:

1. To “move the escape key management code” to Obsidian, we’re utilizing CodeMirror’s triggerOnKeyDown technique with a simulated KeyboardEvent. This method works as a result of Obsidian makes use of CodeMirror as its textual content editor part.

2. All the time present consumer settings to customise the conduct (e.g., escape sequence, button place, gesture sort).

3. Check totally on totally different iOS variations and system sizes to make sure compatibility.

4. Think about combining a number of strategies (e.g., each a button and a gesture) to supply customers with choices.

5. Implement correct cleanup within the onunload technique to take away any added parts or occasion listeners.
