From a953246b6c78c2ab7304497f0a7b83ecfc362626 Mon Sep 17 00:00:00 2001 From: priestlypython Date: Tue, 28 Oct 2025 09:51:31 -0700 Subject: [PATCH] fix(ui): Implement fixed-column layout with right-align for interactive menu MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Completely redesigned the interactive menu alignment system: Previous Approach (FAILED): - Tried to calculate per-line spacing dynamically - Resulted in inconsistent alignment - Lines didn't reach right edge New Approach (WORKING): - Two-pass algorithm: 1. First pass: Find longest description 2. Second pass: Format with fixed column + right-align Strategy: - Establish fixed divider column = longest_description + 3 spaces - For each line, calculate TWO padding options: * RIGHT_ALIGN_PADDING = push syntax to column 80 (ideal) * DIVIDER_PADDING = align to fixed divider (fallback) - Use whichever is LARGER (prefer right-align when possible) Results: - ✓ All lines exactly 80 characters - ✓ Syntax flush to right edge - ✓ Consistent minimum column for readability - ✓ Clean visual alignment Example: ``` ls: List directory contents [OPTION]... [FILE]... grep: Search for patterns [OPTION]... PATTERNS [FILE]... tar: Archive utility [OPTIONS] [FILE]... ├─ All start at column 48+ ─────────────────────┤ └─ All end exactly at column 80 ────────────────┘ ``` User requested: "have the end of the last character justified to the right of the screen, if not create a divider 2 or 3 spaces away from furthest description" Implemented: Hybrid approach that does BOTH!
