macOS: cmd-click fails to open file paths containing tilde (~)

[AlexFeijoo44]

Description

Cmd-clicking a file path containing ~ (e.g. ~/Documents/file.txt) fails to open the file on macOS. The path highlights and appears clickable, but nothing happens.

Absolute paths (e.g. /Users/username/Documents/file.txt) work correctly.

Root Cause

In Ghostty.App.swift's openURL(), when the URL string has no scheme it falls through to:

url = URL(filePath: action.url)

Swift's URL(filePath:) does not perform tilde expansion. A path like ~/Documents/file.txt produces a URL pointing to a non-existent file, and NSWorkspace.open silently fails.

Suggested Fix

Use NSString.expandingTildeInPath to resolve ~ before constructing the file URL:

let expandedPath = NSString(string: action.url).expandingTildeInPath
url = URL(filePath: expandedPath)

Reproduction

1. Run a terminal application that outputs file paths with ~ prefixes (e.g. Claude Code outputs Written to ~/Sites/file.md)
2. Cmd-click the path in Ghostty on macOS
3. The file does not open (fails silently)

Environment

• Ghostty 1.2.3 (stable)
• macOS 15 (Darwin 24.6.0)
