FlexibleSUSY: Meta code – Hepforge

First, familiar things are easier to understand. Whenever you are considering a style question, ask yourself: The following two expressions are equivalent: If you use methods generically, you can abbreviate Object. It is also easier to remove the code fragment or to move it somewhere else.

It makes JavaScript a cleaner language see Strict Mode. It is a hack you are accessing a prototype property via an instance. However, it is usually better to use a more explicit alternative such as Math.

Here, a block is more closely associated with the header of its statement; it starts after it, in the same line.

The rationale is that this is what a named function expression looks like if you remove the name: If you need to know a concept to understand the code, you can either include the name of the concept in an identifier or mention it in a comment.

Put the conditional operator in parentheses This helps with reading, because it is easier to make out the scope of the operator: This is more self-explanatory and safer than comparing with undefined or checking for truthiness:. JavaScript is only so forgiving e.

Tight whitespace I like relatively tight whitespace. The idea is to complement existing style guides rather than to replace them.

However, you have to find ways to recover gracefully from failure when your code is in production. Most of them have generally emtacode answers. I prefer four spaces per level of indentation, because that makes the indentation more visible. The preceding code has the same effect and intention as the following code, which is why it should be written that way:.

For most code, the time used for reading it is much greater than the time used for writing it. Documentation should fill in the blanks left by the code and the comments.

One reason for that is objective. I also like to keep object-oriented and functional mechanisms separate: Always use new when creating an instance. To write such code, use descriptive identifiers and break up long functions or methods into smaller subfunctions. Others have to be defined per project.

6.2 Metacode

Code Should Be Consistent. Metacodde should explain what is happening; it should be self-explanatory. Three parts of a code base help: Using the Or operator to provide default values is a common pattern—for example, for parameters: It should also contain a glossary for all important concepts. The rationale is that this is what a mehacode function expression looks like if you remove the name:. A Meta Code Style Guide. It has been inherited from Java and most style guides recommend it.

Therefore, redBalloon is easier to read than rdBlln.

JavaScript has many great style guides. There are two important rules for writing consistent code. That can mean that using familiar, slightly more verbose, constructs can be preferable. I like relatively tight whitespace. The model is written English: And there are spaces after commas: For constructors, it is important to use strict mode, because it protects you against forgetting the new operator for instantiation.

The advantages mdtacode this approach are that deleting, inserting, and rearranging lines is simpler and the lines are automatically indented correctly. It should tell you how to get started with the code base and provide you with the big picture. Someone reading the code can then turn to the documentation to find out more about the concept.
