An up-to-date version of this and other files can be found in my CommandLineTools project on GitHub.
This is a little program I wrote on request. Someone had used Timo Salmi’s ECHOC command line program, but it ruined the buffer if the window was not 80×25. The person asking had seen my Console unit and asked me if I could write a program that did the same, using the Console unit.
The program outputs the main part of the command line using the foreground and background colours given. Using the Console unit, it was really a piece of cake.
I removed the dependency on the Console unit.
echoc bg fg <text>
The fg and bg parameters can have values of 0..15 and constitute the foreground and background colour of the line respectively. The colours are the colours given in Console.pas:
const // Background and foreground colors Black = 0; Blue = 1; Green = 2; Cyan = 3; Red = 4; Magenta = 5; Brown = 6; LightGray = 7; // Foreground colors DarkGray = 8; LightBlue = 9; LightGreen = 10; LightCyan = 11; LightRed = 12; LightMagenta = 13; Yellow = 14; White = 15;
Blinking is not supported, and the blink bit will set the top bit of the background colour, so you have all 16 colours shown above as background too.
The rest of the parameters is simply displayed, each parameter separated by one space character. But if you put parameters in quotes, the text will be taken literally, and multiple spaces will be displayed, if they appear in the string.
The original program would not display any newlines, so to get newlines, you had to do something like:
@echo off echo. echoc 15 0 This is black on white echo. echoc 14 12 This is bright red on yellow echo. echo.
I decided to add a special character to the string to indicate a newline: ^. So now you can do:
@echo off echoc 15 0 "^This is black on white^" echoc 14 12 "This is bright red on yellow^^^with newlines^^"
Plase respect the license in the files.
I may improve or enhance echoc myself, and I will try to post changes here. But this is not a promise. Please don’t request features.
