How to define a new concept

concept newFile:

    props:
        name    

    pre:
        import os
        os.path.isfile(name) == False
    
        
    post:
        import os
        os.path.isfile(name) == True
    
    main:
        f = open(name)
        f.close()
        __context__.add(newFile, name, f)

example

create a new file named MyFirstFile.txt => newFile("MyFirstFile.txt")

concept newFile:

props:
    name
    path

pre:
    import os
    os.path.isfile(path) == False

    
post:
    import os
    os.path.isfile(path) == True

main:
    import os
    f = open(name)
    f.close()
    sheeka.add(File(name, path))

concept open:

pre:
    self.is_opened == False
    
post:
    self.is_opened == True
    
main:
    self.open

open the door => d = get_instance(door) && get_concept(open).call(d)

concept File:

props:
    name
    path
    
 def open(): 
 
 
 def close():

open the file toto.txt => get_concept(open).call(File(path="toto.txt", name="toto.txt))

concept is_the_opposite:

props:
    a, b
    
test:
    a.pre == not b.pre && a.post == b.post

print all concepts

concepts print all

concept print:

main:
    print(self)

concept all:

main:
    self.find_all()
