#
# This is designed to illustrate the various features
# of the 'tconfpy' configuration language.
#
# Test this out by running the following command
#
#      python test-tc.py debug litvars example.cfg
# OR   python test-tc.py symtbl debug litvars example.cfg
#
# Whitespace is ignored and used here for neatness
# Everything is case-sensitive except values for booleans


#####
# Creating And Modifing Variables
#####

foo = 123          # Creates variable 'foo' and sets its value to "123"
foo = bar          # Changes the value of 'foo' to "bar"


#####
# Variable References - Getting The Value Of A Variable
#####

boing = [foo]      # Creates variable 'boing' and sets its value to "bar"

#####
# Accessing Environment Variables
#####

boo   = [$USER]    # Creates varaible 'boo' and assigns it the value
                   # of the environment variable 'USER'.  This will
                   # cause an error of 'USER' is not defined.

#####
# Indirect variable access
#####

[foo] = baz    # Creates variable 'bar' and sets its value to "baz"


#####
# Namespaces
#####

[NS1]          # Changes namespace to 'NS1'

foo = 100      # Creates 'NS1.foo' and sets its value to "100'

NAMESPACE=NS2  # Changes namespace to 'NS2'

bar = [.NS1.foo]   # Sets 'NS2.bar' to "100" - notice the escaped variable reference

NAMESPACE =    # Reset namespace back to root - can also be done with [] on line by itself


#####
# Existential Conditionals
#####


# Logical AND

                  # Exist for this to be true

.else             # If either or both did not exist - this is optional

    ifall = FALSE
