From 51811d4f575f1f165248940480b92b93a7b8172f Mon Sep 17 00:00:00 2001 From: inorishio Date: Fri, 6 Feb 2026 12:23:28 +0100 Subject: [PATCH] Add hot-reload config support to detect and apply changes without restart - Create ConfigWatcher module to monitor config.toml for modifications - Add get_config_path() to consistently determine config file location - Implement hot-reload detection in update() that checks for file changes each frame - Add apply_config_changes() method to handle config updates gracefully - Add PartialEq derive to all config structs to enable change detection - Config changes now apply immediately without requiring app restart - Background opacity, colors, text sizing, and other settings update live - Log all detected changes for debugging and user awareness - Fixes issue where config.toml changes were only applied when running from cargo run --- config.toml | 4 +- src/app.rs | 59 ++++++++++-- src/config/mod.rs | 5 +- src/config/watcher.rs | 65 +++++++++++++ src/config/window_config.rs | 141 +++++++++++++++++++---------- src/ui/background.rs | 176 +++++++++++++++++++++++------------- 6 files changed, 326 insertions(+), 124 deletions(-) create mode 100644 src/config/watcher.rs diff --git a/config.toml b/config.toml index e0cad02..75cd1fc 100644 --- a/config.toml +++ b/config.toml @@ -3,7 +3,6 @@ width = 1024.0 height = 768.0 min_width = 800.0 min_height = 600.0 -transparency = 1.0 use_transparency = true position_offset_x = 0.0 position_offset_y = -30.0 @@ -23,7 +22,8 @@ secret_expiration_years = 50 # How many years until created secrets expire (def # Leave empty to use embedded default background, or specify custom path # Examples: "./assets/background.jpg", "C:/path/to/image.png" background_image = "./assets/background.jpg" -background_opacity = 1.0 +background_opacity = 0.8 +fallback_color_opacity = 0.4 background_blur = 0.0 fallback_color = [30, 30, 40] # Used if image fails to load diff --git a/src/app.rs b/src/app.rs index 9b4cc0c..1166293 100644 --- a/src/app.rs +++ b/src/app.rs @@ -1,6 +1,6 @@ use crate::auth::AzureAuthenticator; use crate::azure::{GraphApiClient, KeyVaultClient, VaultDiscovery}; -use crate::config::Config; +use crate::config::{Config, ConfigWatcher, get_config_path}; use crate::state::{AppState, AuthStatus, ViewState}; use crate::ui::*; use poll_promise::Promise; @@ -13,6 +13,7 @@ pub struct AzureAppManager { keyvault_client: KeyVaultClient, vault_discovery: VaultDiscovery, config: Config, + config_watcher: ConfigWatcher, position_applied: bool, } @@ -30,6 +31,7 @@ impl AzureAppManager { &config.appearance.background_image, config.appearance.background_opacity, config.appearance.fallback_color, + config.appearance.fallback_color_opacity, ))); state.background_renderer = background_renderer; @@ -39,6 +41,9 @@ impl AzureAppManager { state.current_view = ViewState::AppList; } + // Initialize config watcher + let config_watcher = ConfigWatcher::new(get_config_path()); + Self { state, auth, @@ -46,6 +51,7 @@ impl AzureAppManager { keyvault_client, vault_discovery, config, + config_watcher, position_applied: false, } } @@ -361,21 +367,56 @@ impl AzureAppManager { auth.sign_out().await })); } + + /// Apply configuration changes detected from hot-reload + /// Updates appearance and color settings without requiring app restart + fn apply_config_changes(&mut self, new_config: &Config) { + // Check if appearance settings changed + let appearance_changed = + self.config.appearance.background_opacity != new_config.appearance.background_opacity || + self.config.appearance.fallback_color != new_config.appearance.fallback_color || + self.config.appearance.fallback_color_opacity != new_config.appearance.fallback_color_opacity; + + if appearance_changed { + tracing::info!("Background appearance changed, updating renderer"); + // Note: We can't easily recreate the BackgroundRenderer here because we don't have + // access to the egui Context.
