Neon Vision Editor

Neon Vision Editor Logo

A lightweight, modern macOS text editor focused on speed, readability, and fast automatic syntax highlighting.

It is intentionally minimal: quick edits, fast file access, no IDE bloat.

Release Download: https://github.com/h3pdesign/Neon-Vision-Editor/releases

. . .

Status: beta
Platform target: macOS 26 (Tahoe) Built/tested with Xcode Apple Silicon: tested / Intel: not tested

Download

Prebuilt binaries are available via GitHub Releases:

  • Latest release: v0.4.1-beta
  • Architecture: Apple Silicon (Intel not tested)
  • Notarization: not yet

If you don’t want to build from source, this is the recommended path:

  • Download the .zip or .dmg from Releases
  • Move the app to /Applications

Quick install (curl)

Install the latest release directly:

curl -fsSL https://raw.githubusercontent.com/h3pdesign/Neon-Vision-Editor/main/scripts/install.sh | sh

Install without admin password prompts (user-local app folder):

curl -fsSL https://raw.githubusercontent.com/h3pdesign/Neon-Vision-Editor/main/scripts/install.sh | sh -s -- --appdir "$HOME/Applications"

Gatekeeper (macOS 26 Tahoe)

If macOS blocks the app on first launch:

  1. Open System Settings
  2. Go to Privacy & Security
  3. Scroll down to the Security section
  4. You will see a message that Neon Vision Editor was blocked
  5. Click Open Anyway
  6. Confirm the dialog

After this, the app will launch normally.

Why this exists

Modern IDEs are powerful but heavy.
Classic macOS editors are fast but stagnant.

Neon Vision Editor sits in between:

  • Open files instantly
  • Read code comfortably
  • Edit without friction
  • Close the app without guilt

No background indexing. No telemetry. No plugin sprawl.

Changelog

Editor

  • Added regex-capable Find/Replace with Replace All and quick toolbar access.
  • Improved focus and editor interaction behavior overall.
  • Added Cmd+P Quick Open plus a quick file switcher panel integration.
  • Extended editor command handling for faster navigation and file switching.
  • Kept fallback behavior to protect caret focus and text input stability.

Project navigation

  • Added a right-side project structure panel with recursive folder tree browsing.

Vim mode

  • Added basic Vim navigation and a Quick Open workflow in the editor.
  • Added Vim mode toggle support to the editor command set.
  • Implemented core normal-mode movement keys (h/j/k/l) and insert-mode transitions.
  • Wired Vim mode state updates through notifications for UI/status sync.

Windows & UI

  • Added a dedicated New Window flow that opens blank/isolated windows.
  • Added richer window controls in the toolbar (including sidebar/window toggles).
  • Improved sidebar and window-state handling across the app.
  • Improved translucency support in editor/window surfaces.
  • Removed the extra inner-edge border and tuned card/container visual balance.

Language support & highlighting

  • Added/expanded local language detection heuristics.
  • Improved syntax highlighting behavior (including Markdown edge cases).
  • Added comprehensive PHP and CSV language support.
  • Refined JSON/TOML syntax highlighting.

Onboarding & docs

  • Documented Homebrew installation.
  • Added a first-launch Welcome Tour sheet with richer feature messaging.
  • Kept iOS/iPad paged tour behavior while using a macOS-compatible TabView style.

Menus

  • Consolidated duplicate View menu entries into the system View menu.
  • Shortened Diagnostics menu labels and entries (compact status/check/RTT text).

Internal & distribution

  • Refactored the large ContentView into modular files/extensions for easier maintenance and faster iteration.
  • Hardened security and improved App Store distribution readiness.

Non-goals (by design)

  • X No plugin system (for now)
  • X No code intelligence (LSP, refactors) but simple autocomplete
  • X No Electron, no cross-platform abstraction layer

This is not an IDE. That is intentional.

Requirements

  • macOS 26 (Tahoe)
  • Xcode compatible with macOS 26 toolchain
  • Apple Silicon recommended

Support

If you find Neon Vision Editor useful and want to support its development:

Build from source

git clone https://github.com/h3pdesign/Neon-Vision-Editor.git
cd Neon-Vision-Editor
open "Neon Vision Editor.xcodeproj"

Homebrew install option

If you use Homebrew, you can install via cask:

brew tap h3pdesign/tap
brew install --cask neon-vision-editor

If Homebrew asks for an admin password, it is usually because it installs casks into /Applications. To avoid that, use:

brew install --cask --appdir="$HOME/Applications" neon-vision-editor
