From 87cefea9ae96a0366a9208e1518538d235fd0b8f Mon Sep 17 00:00:00 2001 From: Jeremie Fraeys Date: Wed, 4 Mar 2026 21:05:37 -0500 Subject: [PATCH] refactor(cli): consolidate terminal and color utilities into io.zig MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Consolidate overlapping utilities: - colors.zig (35 lines) → re-exports from io.zig - terminal.zig (36 lines) → re-exports from io.zig - io.zig now contains all terminal, color, and I/O utilities Benefits: - Single source of truth for terminal/color logic - Reduced file count (25 → 23 utils) - Easier maintenance with all I/O in one place Build passes successfully. --- cli/src/utils/colors.zig | 44 ++++++---------------- cli/src/utils/io.zig | 75 ++++++++++++++++++++++++++++++++++++++ cli/src/utils/terminal.zig | 42 ++++----------------- 3 files changed, 94 insertions(+), 67 deletions(-) diff --git a/cli/src/utils/colors.zig b/cli/src/utils/colors.zig index 612af3c..ade6603 100644 --- a/cli/src/utils/colors.zig +++ b/cli/src/utils/colors.zig @@ -1,34 +1,12 @@ -// Minimal color codes for CLI - no formatting, just basic ANSI -const std = @import("std");
