Usage
Initialization
Create an instance of the Platform and initialize it. Only one initialized instance can exist at runtime. The platform cannot be re-initialized after stopping.
val platform = createPlatformInstance()
platform.init()
Creating project
Open a project or a separate file and get an instance of the Project.
val project = platform.openProject("/path/to/project")
val singleFileProject = platform.openFile("/path/to/file")
Adding libraries
project.addLibraries("jars/kotlin-stdlib.jar")
If a directory is specified, all libraries from it and all its subdirectories will be loaded.
Creating compose component
Create an instance of the ProjectFile that contains information about the project and the file to be edited. And pass it to the CodeEditor component.
val projectFile = createProjectFile(
project = project,
projectDir = "/path/to/project",
absoluteFilePath = "/file/to/edit"
)
CodeEditor(projectFile)
val singleFile = createProjectFile(
project = singleFileProject,
absoluteFilePath = "/path/to/file"
)
CodeEditor(singleFile)
Closing project
project.closeProject()
Stopping
platform.stop()
Closes all open projects and deletes temporary files.
Diagnostic messages
The editor supports the output of diagnostic messages. To do this, pass the list of DiagnosticElement to the component.
