Detailed Description

Helper class to download definition file updates.

With the DefinitionDownloader you can download new and update existing syntax highlighting definition files (xml files).

An example that updates the highlighting Definitions and prints the current update progress to the console may look as follows:

auto downloader = new DefinitionDownloader(repo); // repo is a pointer to a Repository
 
// print update progress to console
QObject::connect(downloader, &DefinitionDownloader::informationMessage, [](const QString &msg) {
    std::cout << qPrintable(msg) << std::endl;
});
 
// connect to signal done to delete the downloader later
QObject::connect(downloader, &DefinitionDownloader::done,
                 downloader, &DefinitionDownloader::deleteLater);
downloader->start();

Constructor & Destructor Documentation

DefinitionDownloader()

DefinitionDownloader::DefinitionDownloader ( Repository * repo, QObject * parent = nullptr )

explicit

Constructor.

The Repository repo is used as reference to compare the versions of the existing Definitions with the ones that are available online.

Optionally, parent is a pointer to the owner of this instance.

Member Function Documentation

done

void KSyntaxHighlighting::DefinitionDownloader::done ( )

signal

This signal is emitted when there are no pending downloads anymore.

informationMessage

void KSyntaxHighlighting::DefinitionDownloader::informationMessage ( const QString & msg )

signal

Prints the information about the current state of the definition files.

If all files are up-to-date, this signal is emitted informing you that all highlighting files are up-to-date. If there are updates, this signal is emitted for each update being downloaded.

start()

void DefinitionDownloader::start

(

)

Starts the update procedure.

Once no more updates are available (i.e. either the local definition files are up-to-date, or all updates have been downloaded), the signal done() is emitted.

During the update process, the signal informationMessage() can be used to display the current update progress to the user.
