Just another simple Karel robot

This project provides a command-line-interface (CLI) or a html interface (WEB).

The Pixel Art was created by https://www.fiverr.com/pixelquato

Running WEB

You can either access the web version at https://oglimmer.github.io/karel-robot-js/ or run it yourself:

docker run --rm -it -v $(pwd)/src:/usr/share/nginx/html:ro -p 8080:80 nginx

Preperation for CLI

You need to have nodejs installed. I've tested it with Nodejs V18.

npm ci

Running CLI

echo '
repeat until not house
  if is random
    turnleft
  end, else
    move
  end
end
'|node src/cli.js

you can also create a text file (code.txt) and put the commands into it, then run it via:

cat code.txt | node src/cli.js

you can also change the delay between 2 steps and the initial board configuration:

cat code.txt | node src/cli.js --field '{"walls":[[3,3],[3,4],[3,5]],"packages":[[7,7,2]],"home":[9,9],"meeple":[9,0]}' --d 100

Syntax

The syntax consists of commands and blocks.

block:

A block is one or more commands

command:

example

learn leftelserandom
  if is random
    turnleft
  end, else
    move
  end
end
repeat until not house
  leftelserandom
end
repeat 4-times
  if not east
    move
    log "move east"
  end
end
say "we have done it!"
