From 6568d3301329831ac9f6d7a1c5e9b3ca64f7552d Mon Sep 17 00:00:00 2001 From: Thomas Farstrike Date: Sat, 10 Jan 2026 20:49:25 +0100 Subject: [PATCH] refactor(appstore): extract DRY helpers and consolidate duplicated code - Extract _apply_default_styles() helper to eliminate 12+ repeated widget style calls - Extract _add_click_handler() helper to consolidate 6 repeated event registrations - Consolidate backend config getters into single _get_backend_config() method - Simplify badgehub_app_to_mpos_app() with safer .get() defaults instead of try-except - Extract _cleanup_temp_file(), _update_progress(), _show_progress_bar(), _hide_progress_bar() helpers - Refactor uninstall_app() and download_and_install() to use new progress helpers - Use getattr() for cleaner attribute checking Eliminates ~85 lines of duplicated logic while preserving all functionality, comments, and debug prints. Improves maintainability and code clarity. --- .../assets/app_detail.py | 153 ++++++++++++------ .../assets/appstore.py | 127 +++++---------- 2 files changed, 146 insertions(+), 134 deletions(-) diff --git a/internal_filesystem/builtin/apps/com.micropythonos.appstore/assets/app_detail.py b/internal_filesystem/builtin/apps/com.micropythonos.appstore/assets/app_detail.py index 88d10931..bd5ea588 100644 --- a/internal_filesystem/builtin/apps/com.micropythonos.appstore/assets/app_detail.py +++ b/internal_filesystem/builtin/apps/com.micropythonos.appstore/assets/app_detail.py @@ -24,6 +24,36 @@ class AppDetail(Activity): app = None appstore = None + @staticmethod + def _apply_default_styles(widget, border=0, radius=0, pad=0): + """Apply common default styles to reduce repetition""" + widget.set_style_border_width(border, 0) + widget.set_style_radius(radius, 0) + widget.set_style_pad_all(pad, 0) + + def _cleanup_temp_file(self, path="tmp/temp.mpk"): + """Safely remove temporary file""" + try: + os.remove(path) + except Exception: + pass + + async def _update_progress(self, value, wait=True): + """Update progress bar with optional wait""" + self.progress_bar.set_value(value, wait) + if wait: + await TaskManager.sleep(1) + + def _show_progress_bar(self): + """Show progress bar and reset to 0""" + self.progress_bar.remove_flag(lv.obj.FLAG.HIDDEN) + self.progress_bar.set_value(0, False) + + def _hide_progress_bar(self): + """Hide progress bar and reset to 0""" + self.progress_bar.set_value(0, False) + self.progress_bar.add_flag(lv.obj.FLAG.HIDDEN) + def onCreate(self): print("Creating app detail screen...") self.app = self.getIntent().extras.get("app") @@ -35,8 +65,7 @@ class AppDetail(Activity): app_detail_screen.set_flex_flow(lv.FLEX_FLOW.COLUMN) headercont = lv.obj(app_detail_screen) -
