# This is designed to illustrate the various features
# of the 'tconfpy' configuration language.
#
#####
 
foo = 123 # Creates variable 'foo' and sets its value to "123"
foo = bar # Changes the value of 'foo' to "bar"
Foo = blat # Variable names are case sensistive: New variable 'Foo' introduced here
 
 
#####
# Variable References - Getting The Value Of A Variable
#####
 
boing = [foo] # Creates variable 'boing' and sets its value to "bar"
 
#####
# Indirect variable access
#####
 
[foo] = baz # Creates variable 'bar' and sets its value to "baz"
 
 
#####
# 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

# Some of these examples purposely introduce a type/value
# error to illustrate how 'tconfpy' does validation.
 
 
# Write Protection
 
ro1 = Something # Error: 'ro1' is a Read Only variable
 
 
# Type Enforcement
 
int1 = 4s # Error: 'int1' only accepts integers
int1 = 4s # Error: 'int1' only accepts integers
 
 
# Value Enforcement
 
int1 = 11 # Error: Value must be one of 1, 2, or 23
int1 = 11 # Error: Value must be one of 1, 2, or 23
 
 
# Value Enforcement For Namespace Names
 
# You can make this fail if you supply 'test-tc.py' the 'limitns' option
 
[XYZ] # Error: Namespaces are limited to strings starting with 'NS'
[] # But this always works because the root namespace is always legal
[XYZ] # Error: Namespaces are limited to strings starting with 'NS'

# Enforcing String Content
 
str1 = box # Fine
str1 = bax # Also Fine
str1 = Bax # Also Fine
str1 = FunStuff # Error: Does not match any of the validation regular expressions
 
# Enforcing String Lengths
 
str1 = ab # Too short: must be at least 3 characters long
str1 = abcccccccccccc # Too long: must be 8 or less characters long
 
 
# Setting Booleans
 
# This is the one case where the right-hand-side of the assignment is
# INsensitive to case.
 
# Booleans can be set with: Yes/No, True/False, 1/0, and On/Off

# No matter how you set it, the *value* of a boolean is always stored as
# 'True' or 'False'. This matters when doing Comparison Conditionals
