## Development Setup
|
|
You may already have an editor or IDE you want to use. In any case we provide a pre configured [Visual Studio Code](#visual-studio-code) setup.
|
|
|
|
## Workflow
|
|
|
|
### Issue
|
|
|
|
> TODO
|
|
|
|
### Pull requests
|
|
|
|
- Create a feature branch from the default branch (`master`) and merge back against that branch.
|
|
- It's OK to have multiple small commits as you work on the PR - GitHub automatically squashes them before merging.
|
|
- Make sure tests pass.
|
|
- If adding a new feature:
|
|
- Provide a convincing reason to add this feature. Ideally, you should open a suggestion issue first and have it approved before working on it.
|
|
- If fixing bug:
|
|
- If you are resolving an open issue, add `(fix #xxxx)` (`#xxxx` being the issue ID) in your PR title for a better release log, e.g. `chore(feat): implement SSR (fix #1234)`.
|
|
- Provide a detailed description of the bug in the PR.
|
|
|
|
## Code Specification
|
|
|
|
- use QT wherever it's possible (except there is a good reason)
|
|
- use unix line endings (not windows)
|
|
- indent your code with TABs instead of spaces
|
|
- your files should end with a newline
|
|
- names are camel case
|
|
- use utf8 file encoding (ANSI encoding is strictly forbidden!)
|
|
- use speaking names for variables.
|
|
- avoid code dups -> if you write similar code blocks more the 2 times -> refactoring!
|
|
- avoid compiler macros (#ifdef #define ...) where possible
|
|
- class member variables must prefixed with underscore `int _myMemberVar`
|
|
- initializer list on constructors:
|
|
|
|
```c++
|
|
bad:
|
|
MyClass::MyClass()
|
|
: myVarA(0), myVarB("eee"), myVarC(true)
|
|
{
|
|
}
|
|
|
|
MyClass::MyClass() : myVarA(0),
|
|
myVarB("eee"),
|
|
myVarC(true)
|
|
{
|
|
}
|
|
|
|
good:
|
|
MyClass::MyClass()
|
|
: myVarA(0)
|
|
, myVarB("eee")
|
|
, myVarC(true)
|
|
{
|
|
}
|
|
```
|
|
|
|
- pointer declaration
|
|
|
|
```c++
|
|
bad:
|
|
int *foo;
|
|
int * fooFoo;
|
|
|
|
good:
|
|
int* foo;
|
|
```
|
|
|
|
### Logger
|
|
Hyperion has a own logger class with different log levels.
|
|
- Use macros in include/utils/logger.h
|
|
- Don't use the Logger class directly unless there is a good reason to do so.
|
|
``` c++
|
|
// *** including
|
|
#include <utils/logger.h>
|
|
|
|
// creating
|
|
// get a logger, this will create a logger named MAIN with min loglevel INFO, DEBUG messages won't displayed
|
|
Logger * log_main = Logger::getInstance("MAIN");
|
|
|
|
// get a logger, this will create a logger named MAIN with min loglevel DEBUG, all messages displayed
|
|
Logger * log_main = Logger::getInstance("MAIN", Logger::DEBUG);
|
|
|
|
// using
|
|
// basic
|
|
Debug( log_main, "hello folks!");
|
|
Info( log_main, "hello again!");
|
|
Warning( log_main, "something is crazy");
|
|
Error( log_main, "oh to crazy, aborting");
|
|
|
|
// quick logging, when only one message exists and want no typing overhead - or usage in static functions
|
|
Info( Logger::getInstance("LedDevice"), "Leddevice %s started", "PublicStreetLighting");
|
|
|
|
// a bit mor complex - with printf like format
|
|
Info( log_main, "hello %s, you have %d messages", "Dax", 25);
|
|
|
|
// conditional messages
|
|
WarningIf( (value>threshold), log_main, "Alert, your value is greater then %d", threshold );
|
|
```
|
|
The amount of "%" mus match with following arguments
|
|
|
|
#### The Placeholders
|
|
- %s for strings (this are cstrings, when having std::string use myStdString.c_str() to convert)
|
|
- %d for integer numbers
|
|
- %f for float numbers
|
|
- more placeholders possible, see [here](http://www.cplusplus.com/reference/cstdio/printf/)
|
|
|
|
#### Log Level
|
|
* Debug - used when message is more or less for the developer or for trouble shooting
|
|
* Info - used for not absolutly developer stuff messages for what's going on
|
|
* Warning - warn if something is not as it should be, but didn't harm
|
|
* Error - used when an error occurs
|

## Visual Studio Code
|
|
**We assume that you sucessfully compiled Hyperion with the [Compile HowTo](CompileHowto.md) WITHOUT Docker** \
|
|
If you want to use VSCode for development follow the steps.
|
|
|
|
- Install [VSCode](https://code.visualstudio.com/). On Ubuntu 16.04+ you can also use the [Snapcraft VSCode](https://snapcraft.io/code) package.
|
|
- Linux: Install gdb `sudo apt-get install gdb`
|
|
- Mac: ?
|
|
- Open VSCode and click on _File_ -> _Open Workspace_ and select the file `hyperion.ng/.vscode/hyperion.code-workspace`
|
|
- Install recommended extensions
|
|
- If you installed the Task Explorer you can now use the defined vscode tasks to build Hyperion and configure cmake
|
|
- For debugging you need to build Hyperion in Debug mode and start the correct Run config
