The parser engine iterates through all input characters. The Successor array identifies the next state for each transition. The Action array maintains pointers to the function to execute during a specific transition. An empty list acts as the wild char token. The Grammar array stores lists of expected tokens that trigger a transition for a specific state. The parser state chart contains 7 states. Using the CodeĬecho simply redirects the command arguments to the standard output after parsing color information. The last section explains how to embed the cecho utility into a batch file using the Debug.exe program (until Windows Vista). The COLOR command only defines the color of the entire window console.Ĭecho is an enhanced ECHO command line utility with color support, inspired by the CTEXT utility by Dennis Bareis. But in your batch files, the only command available is COLOR. The Win32 API provides some useful functions to interact with the console (see Console Functions in MSDN). Colorized outputs might be useful to draw attention to important information. However, they lack some user-friendly features such as colorizing console outputs. Batch files are useful to deal with repetitive tasks.
