A Logo compiler and/or interpreter for Windows and/or Linux in form of command line tool and/or IDE
E:\projects\SLogo.git\SLogoC\bin\Debug>SLogoC.exe --help
SLogo Compiler (Console) version X.YZ
for Windows and Linux (Mono)
Usage:
SLogoC.exe filename.lgo [options]
Where options can be:
--width=x Where x is a number that define canvas width
--height=y Where y is a number that define canvas height
--output=z Where z is a a name of bitmap filename where result will be saved
or exe file where compiled Logo program will saved
--run=c Where c is a code that will be executed
For example:
SLogoC.exe test.lgo --output=test.bmp "--run=cs snowflake 12"
will load and compile test.lgo, and if that pass fine and without any error,
then execute ClearScreen (cs) and call function snowflake with parameter equal to 12:
E:\projects\SLogo.git\SLogoC\bin\Debug>
Let's we have a file named test.lgo with following content:
to square :length
repeat 4 [ fd :length rt 90 ]
end
to rose
clearscreen
repeat 36 [ square 50 rt 10 ]
end
to main
rose
end
To execute test.lgo, run main and get 200x200px result bitmap we'll use following command
E:\projects\SLogo.git\SLogoC\bin\Debug>SLogoC.exe test.lgo --output=test.bmp --width=200 --height=200
Done in 233 miliseconds
E:\projects\SLogo.git\SLogoC\bin\Debug>
(Note that there are no code via --run switch specified. In this case a main function will be called)
A resulting image will be:
An interpreter is usually something that can interpret source file, run it internally and show results inside itself. All currently known (as far as we know) Logo programs are interpreters
A compiler is usually a program that is able to convert source file to something that can be runnable without that program. In most cases this is EXE file. As far as we know there are no Logo programs that are compilers (except this one)
No. Together with EXE you should send a copy of TurrtleRuntime.dll file
You can save files in JPG, PNG or GIF. Program will automatically recognize format from file extension you specify in command line
