August/2003 1.0 The KLogoTurtle is a interpreter of the LOGO language for KDE desktops. KDE KLogoTurtle The KLogoTurtle is a useful tool for teaching geometry and principles basics of the programming of computer. Childrens can to study mathematic of mode grasping and constructive. KLogoTurtle support commands in several languages. KLogoTurtle is under license GPL and it developed in KDevelop by Euclides Chuma. KLogoTurtle request KDE 3.1 Compiling KLogoTurtle is very easy. The following should do it: 1. `cd' to the directory containing the package's source code and type `./configure' to configure the package for your system. If you're using `csh' on an old version of System V, you might need to type `sh ./configure' instead to prevent `csh' from trying to execute `configure' itself. Running `configure' takes a while. While running, it prints some messages telling which features it is checking for. 2. Type `make' to compile the package. 3. Type `make install' to install the programs and any data files and documentation. 4. You can remove the program binaries and object files from the source code directory by typing `make clean'. That should do it! Should you run into any problems, please report them to the author To use KLogoTurtle is very easy, just type the commands and click Run button. The following tips are importants: Use one command in each line. The variables names are not sensitive case. The numbers are integers positives. The commands to KLogoTurtle in english are: Move to forward producing a line. Format: FORWARD ?? (?? is the quantity of steps) Example: FORWARD 50 Move to backward producing a line. Format: BACKWARD ?? (?? is the quantity of steps) Example: BACKWARD 50 Rotate to left changing the direction. Format: LEFT ?? (?? is the quantity of degrees) Example: LEFT 90 Rotate to right changing the direction. Format: RIGHT ?? (?? is the quantity of degrees) Example: RIGHT 90 Move to position of the axis X. Format: SETX ?? (?? is the position) Example: SETX 100 Move to position of the axis Y. Format: SETY ?? (?? is the position) Example: SETY 100 Down the pen drawing into screen. Format: PENDOWN Example: PENDOWN Up the pen not drawing into screen. Format: PENUP Example: PENUP Change the pen color. Color might to be Green, Red, Blue, Black, Yellow, Gray, Darkblue, Darkgreen, Darkred, Darkyellow. Format: PENCOLOR ?? (?? is the color) Example: PENCOLOR RED Clear the screen. Format: CLEAR Example: CLEAR Move to center position. Format: HOME Example: HOME Hide cursor. Format: HIDETURTLE Example: HIDETURTLE Show cusor. Format: SHOWTURTLE Example: SHOWTURTLE Start a new drawing. Format: NEW Example: NEW Define a variable with a integer number. Format: MAKE name = ?? (?? is a integer number) Example (define variable TEST with 100): MAKE TEST = 100 Show the content of the variable. Format: CONTENT variable Example: CONTENT TEST Sum two integers positive and put result into a variable. Format: SUM variable = ?? + ?? (?? is a integer number) Example: SUM TEST = 10 + 20 Subtract two integers positive and put result into a variable. Format: SUBTRACT variable = ?? - ?? (?? is a integer number) Example: SUBTRACT TEST = 30 - 10 Multiply two integers positive and put result into a variable. Format: MULTIPLY variable = ?? * ?? (?? is a integer number) Example: MULTIPLY TEST = 20 * 20 Divide two integers positive and put result into a variable. Format: DIVIDE variable = ?? / ?? (?? is a integer number) Example: DIVIDE TEST = 30 / 5 Divide two integers positive and put remainder into a variable. Format: REMAINDER variable = ?? / ?? (?? is a integer number) Example: REMAINDER TEST = 50 / 6 Repeat several times a set of commands. Format: REPEAT ?? (?? is the quantity of times) commands END REPEAT Example: (draw a square) REPEAT 4 FORWARD 50 LEFT 90 END REPEAT Define a set of commands with single name. Format: TO name commands END TO Example: (define a square and draw it) TO SQUARE FORWARD 50 LEFT 90 FORWARD 50 LEFT 90 FORWARD 50 LEFT 90 FORWARD 50 LEFT 90 END TO SQUARE Execute the commands if condition is true. Format: (=, <, >, !) IF ?? = ?? (?? is integer number) commands END IF Example: (draw a line) IF 10 < 100 FORWARD 50 END IF
