OpenEuphoria

Other examples of pre-processors include

• eSQL - Allows you to include a .sql file directly. It parses CREATE TABLE and CREATE INDEX statements building common methods to create, destroy, get by id, find by any index, add, remove and save entities.
• make40 - Will process any 3.x script on the fly making sure that it will run in 4.x. It does this by converting variables, constants and routine names that are the same as new 4.x keywords into something acceptable to 4.x. Thus, 3.x programs can run in the 4.x interpreter and translator with out any user intervention.
• dot4 - Adds all sorts of syntax goodies to Euphoria such as structured sequence access, one line if statements, DOT notation for any function/routine call, design by contract and more.
