Getting Started (30 Seconds)

1. Install using curl or Homebrew (below), or download the latest .zip/.dmg from Releases.
2. Move Neon Vision Editor.app to /Applications.
3. Launch the app.
4. Open a file with Cmd+O.
5. Use Cmd+P for Quick Open and Cmd+F for Find & Replace.
6. Toggle Vim mode with Cmd+Shift+V if needed.

Install

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"

Homebrew

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

Tap repository: h3pdesign/homebrew-tap

If Homebrew asks for an admin password, it is usually because casks install into /Applications. Use this to avoid that:

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

If macOS blocks first launch:

1. Open System Settings.
2. Go to Privacy & Security.
3. In Security, find the blocked app message.
4. Click Open Anyway.
5. Confirm the dialog.

Changelog

v0.4.10 (summary)

• Release gate in scripts/release_all.sh now waits for a successful Pre-release CI run on the pushed commit before triggering notarization.
• Hosted notarized workflow now allows an explicit Xcode 16+ fallback path when Xcode 17 is unavailable on GitHub-hosted runners.
• Settings window responsiveness on macOS by deferring/caching editor font list loading.
• Reduced settings-open latency by removing forced full-window redraw calls during appearance application.

v0.4.9 (summary)

• Pre-release CI workflow on main/PR with critical runtime checks, docs validation, and icon payload verification.
• Release dry-run workflow and local scripts/release_dry_run.sh command for pre-tag validation.
• Release runtime policy test suite (ReleaseRuntimePolicyTests) covering settings-tab routing, theme mapping, find-next cursor behavior, and subscription button state logic.
• Unified release automation in scripts/release_all.sh to run preflight checks before tagging and to verify uploaded release assets after notarized publish.
• README changelog summary automation now keeps release summaries version-sorted and limited to the latest three entries.

v0.4.8 (summary)

• Extended release automation coverage for the next tag cycle, including synchronized README/changelog/welcome-tour release content updates.
• macOS settings parity with iOS by wiring the Open in Tabs preference into live window tabbing behavior.
• Welcome Tour release highlights are now aligned with distribution content for current App Store/TestFlight-facing builds.
• Release workflow environment compatibility by removing hard rg dependency from docs validation steps.
• Release pipeline guard failures caused by placeholder release notes (TODO) in the tag section.
