Notifiers send build system events to a front end or may implement a front
|
|
end themselves, displaying warnings and errors for a user.
|
|
|
|
This is different from a logger in a few ways:
|
|
* The structure of the events are defined by this interface.
|
|
* A "progress" level is included allowing signaling completion status to
|
|
users.
|
|
* It's tailored to providing events from a build system.
|
|
|
|
The structure of a message is a dict with a 'type' key. The type key
|
|
determines the remaining keys as follows:
|
|
type | description and remaining keys
|
|
---------- | ------------------------------
|
|
info | A simple message. The 'message' key contains the message
|
|
debug | Another simple message; this one is less useful when compiles
|
|
| are working. Again, the 'message' key contains the message
|
|
progress | A progress indicator, which may include progress as a
|
|
| percentage. The action key includes what action was taken to
|
|
| make this progress, the file key what file was used to make
|
|
| this progress, and the percent key, when present, indicates
|
|
| how far along the build is.
|
|
tool_error | When a compile fails, this contains the entire output of the
|
|
| compiler.
|
|
var | Provides a key, in the 'key' key, and a value, in the 'value'
|
|
| key, for use in a UI. At the time of writing it's used to
|
|
| communicate the binary location to the online IDE.
