## Thank you for making WLED better!
|
|
|
|
Here are a few suggestions to make it easier for you to contribute!
|
|
|
|
### Target branch for pull requests
|
|
|
|
Please make all PRs against the `0_15` branch.
|
|
|
|
### Code style
|
|
|
|
When in doubt, it is easiest to replicate the code style you find in the files you want to edit :)
|
|
Below are the guidelines we use in the WLED repository.
|
|
|
|
#### Indentation
|
|
|
|
We use tabs for Indentation in Web files (.html/.css/.js) and spaces (2 per indentation level) for all other files.
|
|
You are all set if you have enabled `Editor: Detect Indentation` in VS Code.
|
|
|
|
#### Blocks
|
|
|
|
Whether the opening bracket of e.g. an `if` block is in the same line as the condition or in a separate line is up to your discretion. If there is only one statement, leaving out block braches is acceptable.
|
|
|
|
Good:
|
|
```cpp
|
|
if (a == b) {
|
|
doStuff(a);
|
|
}
|
|
```
|
|
|
|
```cpp
|
|
if (a == b)
|
|
{
|
|
doStuff(a);
|
|
}
|
|
```
|
|
|
|
```cpp
|
|
if (a == b) doStuff(a);
|
|
```
|
|
|
|
There should always be a space between a keyword and its condition and between the condition and brace.
|
|
Within the condition, no space should be between the paranthesis and variables.
|
|
Spaces between variables and operators are up to the authors discretion.
|
|
There should be no space between function names and their argument parenthesis.
|
|
|
|
Good:
|
|
```cpp
|
|
if (a == b) {
|
|
doStuff(a);
|
|
}
|
|
```
|
|
|
|
Not good:
|
|
```cpp
|
|
if( a==b ){
|
|
doStuff ( a);
|
|
}
|
|
```
|
|
|
|
#### Comments
|
|
|
|
Comments should have a space between the delimiting characters (e.g. `//`) and the comment text.
|
|
Note: This is a recent change, the majority of the codebase still has comments without spaces.
|
|
|
|
Good:
|
|
```
|
|
// This is a comment.
|
|
|
|
/* This is a CSS inline comment */
|
|
|
|
/*
|
|
* This is a comment
|
|
* wrapping over multiple lines,
|
|
* used in WLED for file headers and function explanations
|
|
*/
|
|
|
|
<!-- This is an HTML comment -->
|
|
```
|
|
|
|
There is no hard character limit for a comment within a line,
|
|
though as a rule of thumb consider wrapping after 120 characters.
|
|
Inline comments are OK if they describe that line only and are not exceedingly wide. |
