Package tpcli is a golang package (and application) that provides a simple three panel terminal-based UI. tpcli is the "Three Panel Command-line Interface". It is both a golang package and an application. This page documents the package. The UI consists of three "panels": a command entry panel, a general output panel and third panel that is either for error output or which records the history of entered commands. The command entry panel starts with focus. It is a single row panel which supports basic shell-emacs bindings (e.g., ^a to go to the start of the line, ^e to the end of the line) and arrow key readline-style history navigation. The UI runs is started as a goroutine. When the user enters a string in the command entry panel and hits <enter>, the command string is delivered on a channel. Text may be written to the general output panel. The third panel serves one of two functions. By default, it is an error output panel. It is just like the general output panel, and differs only semantically. It may alternatively be set to command history panel. In this case, every time the user enters a command string, it is appended to this panel, providing a command history. The user may use <tab> to switch between the panels. Only the command input panel will accept input. If either of the other two panels has focus, the arrow keys may be used to scroll up or down through the text output. The panels may be stacked in any order desired. The default order places the output panel first, then the error output panel, then the command entry panel. If the user hits <esc> or <ctrl>-q, the UI exits. This mean it Stop()s, and an additional function is called. By default, that function is os.Exit(0). However, this may be overridden via OnUIExit(). For convenience, there is also a CommandProcessor that allows you to define patterns for possible commands, and associate those will callback methods when the user enters those commands. Example
