### Отчет по улучшению приложения Budget Planner
#### Введение
В рамках данного задания было реализовано сохранение данных приложения в
localStorage браузера и небольшое изменение **makefile**.
#### Реализованные изменения
1. **Добавленные функции в C коде**:
```C
void saveToLocalStorage() {
// Get all expenses as JSON
char* json = (char*)malloc(MAX_STRING_LENGTH * expenseCount);
if (!json) return;
// Create array of expenses
sprintf(json, "[");
for (int i = 0; i < expenseCount; i++) {
if (i > 0) strcat(json, ",");
char* expense_json = getExpenseJSON(i);
strcat(json, expense_json);
freeMemory(expense_json);
}
strcat(json, "]");
// Call JavaScript to save to localStorage
EM_ASM({
localStorage.setItem('budgetPlanner_expenses', UTF8ToString($0));
}, json);
free(json);
}
void loadFromLocalStorage() {
// Call JavaScript to load data and parse it
EM_ASM({
var stored = localStorage.getItem('budgetPlanner_expenses');
if (stored) {
var expenses = JSON.parse(stored);
Module.ccall('jsClearAllExpenses', 'number', [], []); // Clear existing data
for (var i = 0; i < expenses.length; i++) {
var expense = expenses[i];
Module.ccall('jsAddExpense', 'number',
['string', 'string', 'number', 'string'],
[expense.date, expense.category, expense.amount, expense.description]
);
}
}
});
}
```
2. **Изменения makefile**:
```makefile
# Default target
all: build server
build:
$(CC) $(SOURCES) -s WASM=1 -s ASSERTIONS=1 -s MODULARIZE=1 -s EXPORT_NAME="'BudgetPlanner'" \
-s EXPORTED_FUNCTIONS='["_main","_showHelloMessage","_jsAddExpense","_jsDeleteExpense","_jsClearAllExpenses","_jsGetTotalExpenses","_jsGetExpenseCount","_jsGetCategoryCount","_getExpenseJSON","_getCategoryTotalJSON","_freeMemory","_malloc","_free","_saveToLocalStorage","_loadFromLocalStorage"]' \
-s EXPORTED_RUNTIME_METHODS='["ccall", "cwrap", "stringToUTF8", "UTF8ToString"]' \
$(LDFLAGS) -o index.js
server:
python3 -m http.server 8000
```
Теперь запуск сервера с приложением совершается по умолчанию и **build**
это отдельный таргет.
Помимо этого был изменен список **EXPORTED_FUNCTIONS**, чтобы он включал
добавленные функции.
#### Принцип работы
1. **Сохранение данных**:
- Создание JSON-строки со всеми расходами
- Использование Emscripten для вызова JavaScript функции сохранения
- Корректная работа с памятью (выделение и освобождение)
2. **Загрузка данных**:
- Получение данных из localStorage
- Парсинг JSON-строки
- Очистка существующих данных
- Постраниное добавление сохраненных расходов
#### Результат
Реализованное улучшение обеспечивает:
- Постоянное хранение данных между сессиями
- Автоматическую загрузку при старте
- Сохранение всех функциональных возможностей приложения
- Эффективное использование памяти
