\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 preferences. You can use a predefined style or
define your own style.
To use the Beautifier plugin:
\list 1
\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 Select \uicontrol Help > \uicontrol {About Plugins} > \uicontrol {C++} >
\uicontrol Beautifier to enable the plugin.
\li Select \uicontrol {Restart Now} to restart \QC and load the plugin.
\li Select \uicontrol Edit > \uicontrol Preferences >
\uicontrol Beautifier to specify settings for beautifying files.
\li Select the \uicontrol {Enable auto format on file save} check box to
automatically beautify files when you save them using the tool you
select in the \uicontrol Tool field.
\image qt-creator-beautifier-options-general.png "General Beautifier preferences"
\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.
This setting is applied only when automatically beautifying files on
save. To restrict the MIME types when selecting the menu item to
format the currently open file, specify this option in the
tool-specific tab.
\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.
\image beautifier_options.png "Uncrustify Beautifier preferences"
\li In the \uicontrol Configuration group, specify the path to
the tool executable in the \uicontrol {Artistic Style command},
\uicontrol {Clang Format command}, or
\uicontrol {Uncrustify command} field.
\li In the \uicontrol {Restrict to MIME types} field, define the MIME
types of the files to beautify. This setting is applied when you
select the menu item to format the currently open file.
\li In the \uicontrol Options group, select the configuration file that
defines the style to use in the source files. If you select several
options, they are applied from top down. The available options
depend on the tool.
\list
\li Select \uicontrol {Use file *.astylerc defined in project files}
or \uicontrol {Use file uncrustify.cfg defined in project files},
to use the configuration file \l{Specifying Project Contents}
{defined in the project file} as the configuration file
for the selected tool.
\li Select \uicontrol {Use specific config file} or
\uicontrol {Use file specific uncrustify.cfg} to
use the specified file as the configuration file for the
selected tool.
\li Select \uicontrol {Use file uncrustify.cfg in <$HOME>} or
\uicontrol {Use file .astylerc or acstylerc in <$HOME>} to
use the specified file in the user's home directory as the
configuration file for the selected tool.
\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.
\image qtcreator-beautifier-options-clangformat.png "Clang Format Beautifier preferences"
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.
To specify a fallback style to use if the style configuration
file is not available, use the \uicontrol {Fallback style}
combo box. Select \uicontrol Default to use the default style.
Select \uicontrol None to skip formatting.
\li Select the \uicontrol {Use customized style} option, and
then \uicontrol Add to define your own style.
Define code formatting in the
\uicontrol {Add Configuration} dialog. It provides syntax
highlighting, auto-completion, and context-sensitive help.
For these features, you must have the tool installed.
\image beautifier_editor.png "Add Configuration dialog"
\endlist
\li Select \uicontrol Edit > \uicontrol Preferences > \uicontrol Beautifier
> \uicontrol {Artistic Style}, \uicontrol ClangFormat, or
\uicontrol Uncrustify > \uicontrol {Format Current File} to format
the currently open file.
You can \l{Keyboard Shortcuts}{create keyboard shortcuts} for the
functions.
\endlist
In addition,
ClangFormat provides the \uicontrol {Format at Cursor} command. If you
select it when no text is selected, the syntactic entity under the cursor
is formatted. The \uicontrol {Disable Formatting for Selected Text} command
wraps selected lines within \c {// clang-format off} and
\c {// clang-format on}.
Uncrustify provides the \uicontrol {Format Selected Text} command. If you
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.
