Source Code

Default converter of KARAS is coded to share the algorithm and the code between any language. Therefore, it is not optimized for each language and each environment. These codes have a not a few redundancy. In other words, source code is written with simplest way, and it can be quickly changed when it needs.

This page describe some coding rule of default converter of KARAS.

• Code Column
• Naming Rule
• Operator
• Regex
• Others

Code Column

As long as there is no restriction of language and the standard class library, code column is limited to 100 characters in a single line. Break position is depending on the situation.

Naming Rule

As long as there is no restriction of language and the standard class library, class name and the others are named with following rule.

• Namespace, class, and constant are named with UpperCamel(Pascal) case.
  • If it is restricted, named with lowerCamel case.
• function, instance, and local value are named with lowerCamel case.

I know that some language such as Ruby is using snake_case by convention, but all of the code of KARAS is not using it.

In Javascript, all of the class name is named with lowercase, because the way of including external file is restricted.

Operator

++ and -- are not using to increment or decrement. Because Ruby does not support this way.

When checking the value by using if, it have to use ==. And in Ruby, it must not use unless.

Regex

Because ECMAscript(Javascript) does not have a lookbehind feature in the Regex, KARAS does not use it. For the same reason, named capture groupe is also does not.

Others

Enum, lambda and anonymous class are not used. These can be used to implement efficient processing and more secure design. However, default code never use these features.

Code-block marks { and } which using with if, for, try, or any other cannot be omitted in any case.
