DocsetRegistry

The DocsetRegistry class manages a collection of docsets. It handles loading/unloading docsets, performing searches across all docsets, and emitting signals when docsets change. 
#include <registry/docsetregistry.h>

​
Namespace

Zeal::Registry::DocsetRegistry

​
Inheritance

class DocsetRegistry : public QObject

​
Constructor

​
DocsetRegistry()

explicit DocsetRegistry(QObject *parent = nullptr)
Creates a new docset registry. Parameters:
  • parent - Optional parent QObject
Example: 
auto registry = new Zeal::Registry::DocsetRegistry();
registry->setStoragePath("/path/to/docsets");

​
Model Access

​
model()

QAbstractItemModel *model() const
Returns the item model representing the docsets in this registry. Useful for displaying docsets in Qt views. Returns: Pointer to the abstract item model Example: 
QListView *listView = new QListView();
listView->setModel(registry->model());

​
Storage Path

​
storagePath()

QString storagePath() const
Returns the directory path where docsets are stored. Returns: The storage path

​
setStoragePath()

void setStoragePath(const QString &path)
Sets the directory path where docsets are stored and loads all docsets from that location. Parameters:
  • path - The directory path containing docsets
Example: 
registry->setStoragePath(QDir::homePath() + "/.local/share/Zeal/docsets");

​
Fuzzy Search Settings

​
isFuzzySearchEnabled()

bool isFuzzySearchEnabled() const
Checks if fuzzy search is enabled for all docsets. Returns: true if fuzzy search is enabled

​
setFuzzySearchEnabled()

void setFuzzySearchEnabled(bool enabled)
Enables or disables fuzzy search for all docsets in the registry. Parameters:
  • enabled - Whether to enable fuzzy search
Example: 
registry->setFuzzySearchEnabled(true);
// All searches will now be more lenient with typos

​
Docset Query Methods

​
count()

int count() const
Returns the number of loaded docsets. Returns: The docset count

​
contains()

bool contains(const QString &name) const
Checks if a docset with the given name is loaded. Parameters:
  • name - The docset name to check
Returns: true if the docset exists Example: 
if (registry->contains("python")) {
    qDebug() << "Python docset is loaded";
}

​
names()

QStringList names() const
Returns a list of all loaded docset names. Returns: List of docset names Example: 
QStringList names = registry->names();
for (const QString &name : names) {
    qDebug() << "Loaded:" << name;
}

​
Docset Management

​
loadDocset()

void loadDocset(const QString &path)
Loads a docset from the specified path. Parameters:
  • path - File system path to the docset
Example: 
registry->loadDocset("/path/to/Python.docset");
// Emits docsetLoaded("python") signal when complete

​
unloadDocset()

void unloadDocset(const QString &name)
Unloads a docset with the given name. Parameters:
  • name - The name of the docset to unload
Example: 
registry->unloadDocset("python");
// Emits docsetAboutToBeUnloaded("python") then docsetUnloaded("python")

​
unloadAllDocsets()

void unloadAllDocsets()
Unloads all currently loaded docsets. Example: 
registry->unloadAllDocsets();
// All docsets are removed from the registry

​
Docset Access

​
docset() (by name)

Docset *docset(const QString &name) const
Returns a pointer to the docset with the given name. Parameters:
  • name - The docset name
Returns: Pointer to the docset, or nullptr if not found Example: 
Docset *pythonDocset = registry->docset("python");
if (pythonDocset) {
    qDebug() << "Version:" << pythonDocset->version();
}

​
docset() (by index)

Docset *docset(int index) const
Returns a pointer to the docset at the given index. Parameters:
  • index - The index of the docset
Returns: Pointer to the docset, or nullptr if index is invalid

​
docsetForUrl()

Docset *docsetForUrl(const QUrl &url)
Finds the docset that contains documentation for the given URL. Parameters:
  • url - The documentation URL
Returns: Pointer to the docset, or nullptr if not found Example: 
QUrl docUrl("file:///path/to/docsets/Python.docset/Contents/Resources/Documents/library/string.html");
Docset *docset = registry->docsetForUrl(docUrl);
if (docset) {
    qDebug() << "URL belongs to:" << docset->title();
}

​
docsets()

QList<Docset *> docsets() const
Returns a list of all loaded docsets. Returns: List of docset pointers Example: 
for (Docset *docset : registry->docsets()) {
    qDebug() << docset->name() << "-" << docset->version();
}

​
Search Methods

void search(const QString &query)
Performs an asynchronous search across all loaded docsets. Results are emitted via the searchCompleted signal. Parameters:
  • query - The search query string (may include docset filters like “python:list”)
Example: 
connect(registry, &DocsetRegistry::searchCompleted,
        [](const QList<SearchResult> &results) {
    qDebug() << "Found" << results.size() << "results";
});

registry->search("string");

​
queryResults()

const QList<SearchResult> &queryResults()
Returns the results from the most recent search. Returns: List of search results Example: 
registry->search("list");
// Wait for searchCompleted signal...
const QList<SearchResult> &results = registry->queryResults();

​
Signals

​
docsetLoaded

void docsetLoaded(const QString &name)
Emitted when a docset has been successfully loaded. Parameters:
  • name - The name of the loaded docset
Example: 
connect(registry, &DocsetRegistry::docsetLoaded,
        [](const QString &name) {
    qDebug() << "Docset loaded:" << name;
});

​
docsetAboutToBeUnloaded

void docsetAboutToBeUnloaded(const QString &name)
Emitted just before a docset is unloaded. Use this to clean up any references to the docset. Parameters:
  • name - The name of the docset being unloaded

​
docsetUnloaded

void docsetUnloaded(const QString &name)
Emitted after a docset has been unloaded. Parameters:

connect(registry, &DocsetRegistry::docsetUnloaded,
        [](const QString &name) {
    qDebug() << "Unloaded:" << name;
});

​
searchCompleted

void searchCompleted(const QList<SearchResult> &results)
Emitted when an asynchronous search has completed. Parameters:
  • results - The list of search results
Example: 
connect(registry, &DocsetRegistry::searchCompleted,
        [](const QList<SearchResult> &results) {
    for (const auto &result : results) {
