AppUtil.h

This module contains utilities used by the command-line interpreter parameter-setting shell (app.g), that are most appropriately implemented in C++. These primarily include utilities for reading input commands, parsing and translating input command strings into standard Glish, and formatting meta information and current parameter values for display.

Example

Motivation

The C++ utilities required by app.g are best collected in one associated class.

To Do

i) minimum match.
