Using Text Files as a User Interface

The concept treats plain text files as interactive elements. Instead of graphical widgets, commands are entered via editable files. This approach leverages the familiarity of text editors for input. It can simplify development by avoiding complex UI frameworks. The method is useful for low‑resource environments or scripting tools. Users edit the file, save changes, and the program reads the new data. Feedback can be displayed by writing output back into the same file. The article demonstrates practical examples of this technique.
