From 8bd5b52b0541f86557217b40ee8089598d38aee8 Mon Sep 17 00:00:00 2001 From: S4NKALP Date: Thu, 12 Mar 2026 00:27:37 +0545 Subject: [PATCH] refactor(src/commands): enhance battery command error handling and readability MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Restructure loops, add explicit error handling, improve multi‑line messages, and fix formatting issues. - Enhancements - Use explicit braces for error branches to prevent silent failures - Wrap warning and informational messages in multi‑line `println!` with consistent spacing - Refactor directory reads for Ideapad fallback to avoid nested `let` bindings - Improve parsing and formatting of AMD TDP limit output with clear parentheses - Provide clearer debug logging when writing to threshold files - Bug Fixes - Added missing braces around error handling to ensure proper execution flow - Fixed variable binding scope for `ideapad_entries` to prevent shadowing - Ensured consistent handling of missing `charge_control_end_threshold` across all entries no changes. --- src/commands/battery.rs | 68 ++++++++++++++++-------- src/commands/cooling.rs | 6 +-- src/commands/gpu.rs | 99 +++++++++++++++++++++++++++-------- src/commands/install_rules.rs | 71 +++++++++++++++++++++++++ src/commands/mod.rs | 1 + src/commands/power.rs | 41 +++++++++------ src/commands/status.rs | 36 ++++++++----- 7 files changed, 242 insertions(+), 80 deletions(-) create mode 100644 src/commands/install_rules.rs diff --git a/src/commands/battery.rs b/src/commands/battery.rs index 99c5165..335600f 100644 --- a/src/commands/battery.rs +++ b/src/commands/battery.rs @@ -1,5 +1,4 @@ use crate::cli::BatteryCommands; -use crate::utils::system::assert_root; use log::{debug, error, info}; use std::fs; use std::path::Path; @@ -7,23 +6,21 @@ use std::path::Path; pub fn execute(command: &BatteryCommands) { match command { BatteryCommands::Limit { percent } => { - assert_root(); - if percent < &1 || percent > &100 { error!("Invalid percentage.
