Declarations

In rew, there is a special syntax called declarators.

Example:

It mostly works like the C's declare function.

#declare "sayhello" = print("Hello");

Showcase

sayhello
# will be converted to
print("Hello")

Declaration Scopes

When you declare a syntax, you are declaring it only to the local file, meaning that it'll only work on the same file that it's written on. To pass that, you can use declare*.

# Public Declare
#declare* "myKey" = replacementValue;

Declarators

A declarator is a function that can be used to declare a variable.

#declare* "=myDeclarator" = myDeclarator;

This will define a test case that tests for anything with myDeclarator variableName = ... and converts it to variableName = myDeclarator ....

Example:

#declare* "=myClass" = createMyClass;
myClass myInstance = 'my value'

This will translate to:

myInstance = createMyClass 'my value'

Passing parameters in Declarators

You can pass parameters for declarators to define them.

myClass('some value') myInstance = 'my value'

Which translates to:

myInstance = createMyClass('my value', 'some value')

Known Problems

• Spaces are required during declaration when using a declarator
• Strings don't work well with declare
• The entire feature can make unexpected syntax errors.
