Creating a very simple text editing application on macOS

Proposed by freelancer

5

89d

I will commission the development of a very simple text editor for macOS. The application should be created in Swift (preferred) or possibly React + Electron. I will provide the willing contractor with the interface design and all necessary styling information. The app is basically a text entry box without any styling (bold, lists, italics, etc.) with the ability to export to .PDF and .TXT files. Plus a line/word/character counter, switch interface modes (light, dark), switch font (about 4-6 fonts) and text size. The application must integrate with macOS - the various functions should be accessible from the bar menu, as well as allow you to open a .txt file in the application (option open in...). The application must also be as efficient as possible - it is a word processor. Detailed requirements described in "Required features".

Aplikacja wykorzystująca gniazda TCP/IP (klasy ServerSocket, Socket):

- aplikacja graficzna JavaFX lub wykorzystująca pakiet Swing,

- aplikacja ma symulować działanie sieci sklepów odzieżowych,

- każdy sklep ma zestaw towarów dostępnych na półkach,

- sklepy mają mieć postać graficzną, a "hub" aplikacji - konsolowy

- towary reprezentowane są przez: kod, nazwę, cenę za sztukę, liczbę sztuk

- każdy sklep obsługiwany jest przez moduł pozwalający na: wyszukanie towaru lokalnie i jego sprzedaż, wyszukanie towaru zdalnie i jego przesłanie,

- istnieje aplikacja centralna, która pełni rolę huba - to w niej rejestrowane są sklepy, to przez nią przechodzi cała komunikacja (interfejs huba tekstowy)

- metody wywoływane zdalnie udostępnione w interfejsie huba powinny pozwalać na zarejestrowanie i wyrejestrowywanie modułów oraz obsługę zapytań pochodzących od tych modułów

- metody wywoływane zdalnie udostępnione w interfejsie każdego z modułów powinny umożliwiać zadawanie zapytań o dostępność towaru oraz umożliwiać zgłoszenie żądania jego przesłania (hub będzie „forwardował” te zapytania),

- kodowanie przesyłanej informacji może być dowolne, to jednak zalecane jest kodowanie tekstowe (np. ciąg znaków: "?;id" może oznaczać zapytanie o dostępność towaru o wskazanym id),

- wyklucza się serializację obiektów (metody writeObject lub readObject nie powinny być stosowane).

Załączam uproszczoną wersję kodu i screen do wglądu, który przykładowo przesyła i pobiera dane.
