    \title Beautifying Source Code

    You can use the experimental Beautifier plugin to format your source code
    by using the following external tools:

    \list

        \li \l{http://astyle.sourceforge.net}{Artistic Style}

        \li \l{http://clang.llvm.org/docs/ClangFormat.html}{ClangFormat}

        \li \l{http://uncrustify.sourceforge.net}{Uncrustify}

    \endlist

    The Beautifier plugin parses the source code into component structures, such
    as assignment statements, if blocks, loops, and so on, and formats them as
    specified in the Beautifier options. You can use a predefined style or
    define your own style.

    To use the Beautifier plugin:

    \list 1

62 63 64 65 66 67 68 69 70 71 72
        \li Download and install the tool to use for formatting source code:

            \list
                \li \l{http://sourceforge.net/projects/astyle/files/astyle}
                    {Artistic Style}
                \li \l{http://llvm.org/releases/download.html}{ClangFormat}
                \li \l{http://sourceforge.net/projects/uncrustify/files/uncrustify}
                    {Uncrustify}
            \endlist

            You might have to build the tools from sources for some platforms.

        \li In the \uicontrol {Restrict to MIME types} field, define the MIME
            types of the files to beautify, separated by semicolons. Leave the
            field empty to apply the tool on all files.

        \li Select the \uicontrol {Restrict to files contained in the current
            project} check box to only beautify files that belong to the
            current project.

        \li Select \uicontrol {Artistic Style}, \uicontrol {Clang Format}, or
            \uicontrol Uncrustify to specify settings for the tool you want to
            use.

                    available for Artistic Style and Uncrustify.

                \li For Clang Format, you can use a predefined style, by
                    selecting the \uicontrol {Use predefined style} radio
                    button, and then selecting the style to use from the list of
                    available styles.

                    Select \uicontrol File to load the style configuration from
                    the \c .clang-format or \c _clang-format file located in the
                    same directory as the source file or in one of its parent
                    directories.

    In addition to the \uicontrol {Format Current File} command, ClangFormat
158
    and Uncrustify provide the \uicontrol {Format Selected Text} command. If you
159 160 161
    select it when no text is selected, the whole file is formatted by default.
    To disable this behavior, deselect the
    \uicontrol {Format entire file if no text was selected} check box.
