FlexibleSUSY: Meta code – Hepforge
This kind of local encapsulation makes a code fragment easier to understand in isolation. I prefer four spaces per level of indentation, because that makes the indentation more visible. If a statement contains a block, that block is considered as somewhat separate from the head of the statement: It should tell you how to get started with the code base and provide you with the big picture.
That means that if you want to work with a code base, you need to learn those ideas and concepts.
These are style guides that I like: This helps with reading, because it is easier to make out the scope of the operator: More tips for using constructors are mentioned in Tips for Implementing Constructors.
Instead, this chapter describes meta style rules and surveys existing style guides and established best practices. Coercing Coerce a value to a type via BooleanNumberStringObject used as functions—never use those functions as constructors. Using the Or operator to provide default values is a common pattern—for example, for parameters: Thus, there is no need to write yet another one. It also mentions practices I like that are more controversial. However, you have to find ways to recover gracefully from failure when your code is in production.
First, familiar things are easier to understand.
Meta Imaging Series Codes
But it reduces clutter, and I expect engines to eventually optimize this pattern. Someone mtacode the code can then turn to the documentation to find out more about the concept. 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.
ASI can unexpectedly break up statements:. The model metacide written English: For most code, the time used for reading it is much greater ,etacode the time used for writing it.
This is more self-explanatory and safer than comparing with undefined or checking for truthiness:. Here are some guidelines for doing that:. Whenever you are considering a style question, ask yourself: Prefer Literals to Constructors.
If those functions are small enough and have meaningful names, you can often avoid comments.
Changing undefined explains why. It is also easier to remove the code fragment or to move it somewhere else.
