    \title Get and Install Qt with Command Line Interface
    \brief How to download and install with CLI.

    Use the command line interface with \QOI and \QMT to install, uninstall, update,
    and search components.

    The command line interface supports both \b{interactive and non-interactive
    usage (unattended usage)}. The following topics provide examples and
    information on how you can use the command line interface:

    \list
        \li \l{Downloading \QOI with Command Line Interface}
        \li \l{Component Names For Installation}
        \li \l{Installing Without User Interaction}
        \li \l{Installing With User Interaction}
        \li \l{Uninstalling Packages}
        \li \l{Listing Installed Packages}
        \li \l{Checking Updates}
        \li \l{Updating Packages}
        \li \l{Popular Commands}
        \li \l{Selecting Mirror for Opensource}
        \li \l{Summary of Command Line Interface Usage}
    \endlist

    \section1 Downloading \QOI with Command Line Interface

    You can use the \c curl command on the command line interface to download \QOI.
    To see all the \QOI packages available for different platforms, visit
    \l {\QOI official releases}.

    To download a specific \QOI package with the same name as the remote file,
    use the \c -O (uppercase 'O') option.

    The example command below downloads the \c qt-online-installer-linux-x64-online.run
    package:

    \badcode
    curl -O https://download.qt.io/official_releases/online_installers/qt-online-installer-linux-x64-online.run
    \endcode

    \section1 Component Names for Installation

    \section2 Quick Installation with Alias Packages

    Instead of searching for specific package names for installation, you can
    use alias packages to install the most common configurations. Alias packages
    are a shortcut to include the actual packages for an easier installation
    experience.

    \section3 Listing Existing Alias Packages

    To list the existing alias packages, use the following command on the command
    line interface.

    \e {Using \QOI}:

    \badcode
    <installer executable> search
    \endcode

    For details on the \e{\QOI} executables for different platforms,
    see \l {Installing With User Interaction}.

    \e {Using \QMT}:

    \badcode
    <maintenancetool executable> search
    \endcode

    For details on the \e{\QMT} executables for different platforms,
    see \l {Installing With User Interaction}.

    \section3 Contents of Alias Packages

    The contents of the alias packages are listed in the table below.

    \note Qt \QtVersion release is used in the alias package examples listed below.
    Always remember to use the packages that match the Qt release you are working
    on.

    # Linux: new installation with Qt Online Installer
    qt-unified-linux-x64-[Qt Online Installer version]-online.run install qt\1-sdk
    \endcode

    \section3 Alias Package Options for Windows

    \note The information in this section is valid for the Qt 6.8, Qt 6.9, and
          Qt 6.10 releases.

    \e {Windows on ARM64}

    Only the MSVC binaries (msvc2022-arm64) are installed as other Qt binary
    packages are not available for Windows on Arm (WoA).

    \e {Windows on x86_64}

    By default, only the MinGW binaries are installed.

    However, with \e {Windows on x86_64} you can also install binaries for the
    following toolchains.

    \list
        \li llvm-mingw
        \li msvc2022
        \li msvc2022-arm64 (for cross-compilation)
    \endlist

    Using, for example, the \e {qt\QtVersion-essentials} alias package installs
    the package with the default MinGW binaries.

    To get the \c {Qt essentials} package content with, for example, the MSVC 2022
    binaries, use the corresponding \e {qt\QtVersion-msvc2022-essentials} alias
    package.

    \section2 Listing Non-Alias Packages

    To list the non-alias packages, use the following command on the command
    line interface.

    \e {Using \QOI}:

    \badcode
    <installer executable> search --type package
    \endcode

    For details on the \e{\QOI} executables for different platforms,
    see \l {Installing With User Interaction}.

    \e {Using \QMT}:

    \badcode
    <maintenancetool executable> search --type package
    \endcode

    For details on the \e{\QMT} executables for different platforms,
    see \l {Installing With User Interaction}.

    \section2 Advanced Searching for Specific Installation Packages

    Search available packages with the \c{search} command and regular
    expressions: \b{\c{search <regexp>}}. You can filter the results with
    \b{\c{--filter-packages <regexp>}}. For example, filtering with the display
    name information can help search.

    For example, the following command finds all MSVC 2022 packages for Qt \QtVersion:

    \badcode \QtVersionTag
    search .*\1.*msvc2022
    \endcode

    You get the same result when you filter the search result as follows:

    \badcode \QtVersion
    search --filter-packages DisplayName=MSVC 2022,Version=\1
    \endcode

    As a result, you get the following packages:

    \badcode \QtVersionTag \QtVersion
    <availablepackages>
        <package name="qt.qt6.\1.win64_msvc2022_64" displayname="MSVC 2022 64-bit" version="\2.-0-<timestamp>"/>
        <package name="qt.qt6.\1.win64_msvc2022_arm64" displayname="MSVC 2022 ARM64" version="\2.-0-<timestamp>"/>
    </availablepackages>
    \endcode

    You can also use filtering when you search all Qt versions that some package
    is provided for. For example, search all Qt Charts packages provided for
    Qt versions:

    \badcode
    search --filter-packages DisplayName=charts
    \endcode

    The search result is as follows:

    \badcode
    <availablepackages>
        <package name="qt.qt5.5125.qtcharts" displayname="Qt Charts" version="5.12.5-0-<timestamp>"/>
        <package name="qt.qt6.641.addons.qtcharts" displayname="Qt Charts" version="6.4.1-0-<timestamp>"/>
        <package name="qt.qt5.5123.qtcharts" displayname="Qt Charts" version="5.12.3-0-<timestamp>"/>
    \endcode

    \section1 Installing Without User Interaction

    By default, \QOI or \QMT may ask for
    additional information during installation, which requires user attention.
    Unattended usage via the command line interface is possible by providing all
    the requested information beforehand with appropriate options.

    \section2 New Installation with \QOI

    You can do new installations from the command line interface without user
    interaction as follows:

    \list 1
        \li Define the \e{\QOI} executable.
        \li Define the installation directory with \b{\c{--root}}.
        \li Use the \b{\c{install <list of packages>}} command with \b{options
        for unattended usage}. See the full list of options in
        \l{Options for Unattended Usage}.
    \endlist

    The following examples demonstrate how you install Qt \QtVersion binaries
    with \QOI for Windows, macOS, and Linux. The unattended
    commands automatically accept the licenses (\b{\c{--accept-licenses}}), answer
    all message queries with their default answer (\b{\c{--default-answer}}), and
    skip asking for permission to continue performing (\b{\c{--confirm-command}}):

    \badcode \QtVersionTag
    # Windows: new installation with Qt Online Installer
    qt-unified-windows-x64-[Qt Online Installer version]-online.exe --root C:\Users\[username]\installation_dir --accept-licenses --default-answer --confirm-command install qt.qt6.\1.win64_msvc2022_64

    # macOS: new installation with Qt Online Installer
    qt-unified-macOS-x64-[Qt Online Installer version]-online.dmg --root /home/<username>/installation_dir --accept-licenses --default-answer --confirm-command install qt.qt6.\1.clang_644

    # linux: new installation with Qt Online Installer
    qt-unified-linux-x64-[Qt Online Installer version]-online.run --root /home/<username>/installation_dir --accept-licenses --default-answer --confirm-command install qt.qt6.\1.linux_gcc_64
    \endcode

    \l{Options for Unattended Usage} lists all available options for unattended
    usage.

    \section2 Updating Installation with \QMT

    You can update existing installation from the command line interface without
    user interaction as follows:

    \list 1
        \li Define the \e{\QMT} executable.
        \li Use \b{\c{install <list of packages>}} with \b{options for
        unattended usage}. See the full list of options in
        \l{Options for Unattended Usage}.
    \endlist

    The following examples demonstrate how you add Qt \QtVersion binaries
    with \QMT to an exsting installation on Windows, macOS, and
    Linux. The unattended commands automatically accept the licenses
    (\b{\c{--accept-licenses}}), answer all message queries with their default
    answer (\b{\c{--default-answer}}), and skip asking for permission to continue
    performing (\b{\c{--confirm-command}}):

    \badcode \QtVersionTag
    # Windows: update installation with Qt Maintenance Tool
    MaintenanceTool.exe --accept-licenses --default-answer --confirm-command install qt.qt6.\1.win64_msvc2022_64

    # macOS: update installation with Qt Maintenance Tool
    MaintenanceTool.app/Contents/MacOS/MaintenanceTool --accept-licenses --default-answer --confirm-command install qt.qt6.\1.clang_64

    # linux: update installation with Qt Maintenance Tool
    MaintenanceTool.run --accept-licenses --default-answer --confirm-command install qt.qt6.\1.linux_gcc_64
    \endcode

    \section2 Options for Unattended Usage

    The following table lists all options for unattended command line usage:

    \table
    \header
        \li Option for unattended usage
        \li Description
    \row
        \li \c{--accept-licenses}
        \li Automatically accepts all license agreements.
    \row
        \li \c{--accept-obligations}
        \li In the opensource installations, accepts Qt Open Source usage
        obligations without user input.
    \row
        \li \c{--default-answer}
        \li  Answers all message queries with their default answer.
    \row
        \li \c{--auto-answer <identifier=value>}
        \li In case you want different answers to certain queries, you can use
        this option. For example,
        \c{--auto-answer telemetry-question=Yes,AssociateCommonFiletypes=Yes}.
        See all message identifiers in \l{Message Identifiers for \--auto-answer}.
    \row
        \li \c{--accept-messages}
        \li Accepts all message queries.
    \row
        \li \c{--reject-messages}
        \li Rejects all message queries.
    \row
        \li \c{--confirm-command}
        \li By default, \QOI and \QMT print a summary
        of components to be affected by the option. Then they ask for
        permission to continue acting, to prevent accidental
        changes. This option skips asking for permission to continue.
    \row
        \li \c{--email <your_email>}
        \li Provides the email when you log in from the command line. For more
        information, see \l{Providing Login Information}.
    \row
        \li \c{--pw <your_pw>}
        \li Provides the password when you log in from the command line. For
        more information, see \l{Providing Login Information}.
    \row
        \li \c{--file-query <identifier=value>}
        \li Sometimes \QOI asks for a file or a folder location.
        You can provide the location with \c{--file-query <identifier=value>}.
        For example, \c{--file-query PathForSDP7=<path_to_sdp>}.

        The identifiers are printed into the command line before the actual
        question and message type. You can pick up the identifiers from there.
    \endtable

    \section2 Message Identifiers for \--auto-answer

    Use the \c{--auto-answer} option to provide answers to certain queries. The
    following table lists known identifiers and values used for
    \c{--auto-answer}:

    \table
        \header
        \li ID
        \li Values
        \li Default
    \row
        \li OperationDoesNotExistError
        \li Abort, Ignore
        \li Ignore
    \row
        \li OverwriteTargetDirectory
        \li Yes, No
        \li No
    \row
        \li stopProcessesForUpdates
        \li Retry, Ignore, Cancel
        \li Cancel
    \row
        \li installationErrorWithCancel
        \li Retry, Ignore, Cancel
        \li Cancel
    \row
        \li installationErrorWithIgnore
        \li Retry, Ignore
        \li Ignore
    \row
        \li AssociateCommonFiletypes
        \li Yes, No
        \li Yes
    \row
        \li telemetry-question
        \li Yes, No
        \li Yes
    \endtable

    \section2 Providing Login Information

    \QOI and \QMT have a forced login. The forced
    login uses information on the \e{qtaccount.ini} file if it is available in
    cache. You find \e{qtaccount.ini} as follows:

    \table
    \header
        \li Host
        \li qtaccount.ini location
    \row
        \li Windows
        \li \c{C:\Users\<username>\AppData\Roaming\Qt}
    \row
        \li macOS
        \li \c{/Users/<username>/Library/Application Support/Qt/qtaccount.ini}
    \row
        \li Linux
        \li \c{/home/<username>/.local/share/Qt/qtaccount.ini}
    \endtable

    Optionally, you can login either from the command line using the switches
    for email and password: \c{--email <your_email>} and \c{--pw <your_pw>}.

    Alternatively, you can save the jwt token to the environment variable
    \c{QT_INSTALLER_JWT_TOKEN}. You find the token in the \e{qtaccount.ini} file.

    \section1 Installing With User Interaction

    You can use the command line interface with user interaction as follows:

    \list 1
        \li Define the executable:
            \list
                \li \e{\QOI} if you need to do a new installation.
                \li \e{\QMT} if you need to update an existing
                installation.
            \endlist
        \li When you do a new installation,
        define the installation directory with \c{--root}
        \li  Use \b{\c{install <list of packages>}} to install the listed
        packages.
    \endlist

    The following examples demonstrate how you create a new installation
    of Qt \QtVersion binaries with \QOI for Windows, macOS, and Linux:

    \badcode \QtVersionTag
    # Windows: new installation with user interaction
    qt-unified-windows-x64-[Qt Online Installer version]-online.exe --root C:\Users\[username]\installation_dir install qt.qt6.\1.win64_msvc2022_64

    # macOS: new installation with user interaction
    qt-unified-macOS-x64-[Qt Online Installer version]-online.dmg --root /home/<username>/installation_dir install qt.qt6.\1.clang_64

    # linux: new installation with user interaction
    qt-unified-linux-x64-[Qt Online Installer version]-online.run --root /home/<username>/installation_dir install qt.qt6.\1.linux_gcc_64
    \endcode

    The following examples demonstrate how you update your existing
    installation by installing the Qt \QtVersion binaries with \QMT:

    \badcode \QtVersionTag
    # Windows: update installation with Qt Maintenance Tool
    MaintenanceTool.exe install qt.qt6.\1.win64_msvc2022_64

    # macOS: update installation with Qt Maintenance Tool
    MaintenanceTool.dmg install qt.qt6.\1.clang_64

    # Linux: update installation with Qt Maintenance Tool
    MaintenanceTool.run install qt.qt6.\1.linux_gcc_64
    \endcode

    \section1 Uninstalling Packages

    The command line interface provides two commands for uninstalling packages:

    \list
        \li The \b{\c{remove <list of packages>}} command uninstalls the listed
        packages.
        \li The \b{\c{purge}} command uninstalls all installed packages.
    \endlist

    You should use both commands with \QMT.

    By default, \QMT prints a summary of components to be affected
    by the command. Then the tool asks for permission to continue acting, to
    prevent accidental changes. Use \b{\c{--confirm-command}} to skip asking for
    permission to continue.

    The following example uninstalls the Qt \QtVersion binaries without user
    interaction:

    \badcode \QtVersionTag
    # windows
    MaintenanceTool.exe --confirm-command remove qt.qt6.\1.win64_msvc2022_64

    # macOS
    MaintenanceTool.dmg --confirm-command remove install qt.qt6.\1.clang_64

    # linux
    MaintenanceTool.run --confirm-command remove qt.qt6.\1.linux_gcc_64
    \endcode

    The following examples uninstall all packages and ask for permission to
    continue performing the action:

    \badcode
    # Windows
    MaintenanceTool.exe purge

    # macOS
    MaintenanceTool.dmg purge

    # Linux
    MaintenanceTool.run purge
    \endcode

    \section1 Listing Installed Packages

    The \b{\c{list}} command lists all packages you have installed. Use the
    command with \QMT as follows:

    \badcode
    # Windows
    MaintenanceTool.exe list

    # macOS
    MaintenanceTool.dmg list

    # Linux
    MaintenanceTool.run list
    \endcode

    \section1 Checking Updates

    The \b{\c{check-updates}} command checks the updates that are available for
    the installed packages. Use the command with \QMT as follows:

    \badcode
    # Windows
    MaintenanceTool.exe check-updates

    # macOS
    MaintenanceTool.dmg check-updates

    # Linux
    MaintenanceTool.run check-updates

    \endcode

    \section1 Updating Packages

    The \b{\c{ update}} command updates the installed packages. Use the command
    with \QMT as follows:

    \badcode
    # windows
    MaintenanceTool.exe update

    # macOS
    MaintenanceTool.dmg update

    # linux
    MaintenanceTool.run update
    \endcode

    \section1 Popular Commands

    Use the command \b{\c{<installer_executable> --help}} to study the available
    commands and options. Popular commands are as follows:

    \table
    \header
        \li Command
        \li Usage
    \row
        \li \c{in}, \c{install <pkg ...>}
        \li Installs packages given as an argument. If you don't give any
        packages, installs the default package set.

    \section1 Selecting Mirror for Opensource

    \QOI has an option for selecting a mirror for opensource
    metadata and downloads. Set the mirror from the command line with the
    \b{\c{--mirror}} option.

    For example, use \c{--mirror} as follows:

    \badcode
    installer(.exe) --mirror http://www.nic.funet.fi/pub/mirrors/download.qt-project.org
    installer(.exe) --mirror http://ftp2.nluug.nl/languages/qt
    maintenancetool(.exe) --mirror http://qt.mirror.constant.com
    \endcode

    As the example shows, don't use the full path but use the path before
    '/online' (no forward slash at the end).

    You find the available mirrors from
    \l{https://download.qt.io/online/qtsdkrepository/windows_x86/root/qt/Updates.xml.mirrorlist}.
