\section2 Automatic Formatting and Indentation
The experimental Clang Format plugin uses the
\l{https://clang.llvm.org/docs/LibFormat.html}{LibFormat}
library for automatic formatting and indentation.
To enable the plugin, select \uicontrol Help > \uicontrol {About Plugins} >
\uicontrol {C++} > \uicontrol {ClangFormat}. Then restart \QC to load the
plugin.
\note If you enable the plugin, do not use the \l{Beautifying Source Code}
{Beautifier}, because combining the two can provide unexpected results.
You can use Clang Format to enforce a coding style for a project or the
whole organization. Create a \c {.clang-format} file that contains the
\l{https://clang.llvm.org/docs/ClangFormatStyleOptions.html}
{Clang Format Style Options} to use and save it in the root folder of the
project or one of its parent folders. The plugin searches for the Clang
format file recursively from the directory that contains the source file
up to the file system root.
To specify settings for automatic formatting and indentation:
\list 1
\li Select \uicontrol Tools > \uicontrol Options > \uicontrol {C++}.
\image qtcreator-clang-format-options.png "C++ Clang Format options"
\li Select the \uicontrol {Format instead of indenting} check box to
use the \key {Ctrl+I} keyboard shortcut to format code instead of
indenting it.
\li Select the \uicontrol {Format while typing} check box to apply the
formatting while you type code.
\li Select the \uicontrol {Format edited code on file save} check box
to apply the formatting to the edited code when you save the file.
\li Select the \uicontrol {Override Clang Format configuration file}
check box to create a local configuration file that overrides the
one stored in the file system.
\note This is not recommended, because it defeats the purpose of
a Clang format file.
\li To modify the values in the file, select them in the left-side
column and enter the new values.
\li To view examples of the new values in the right-hand column, select
\uicontrol Apply.
\endlist
To override the \c {.clang-format} file for a project, select
\uicontrol Projects > \uicontrol {Project Settings} >
\uicontrol {Code Style} >
\uicontrol {Override Clang Format configuration file}.
\image qtcreator-code-style-clang-format.png
You can create \c {.clang-format} files that contain the configuration
options of a certain predefined style from the command line. For example,
to create a format file for the LLVM style, enter the following command:
\badcode
clang-format -style=llvm -dump-config > .clang-format
\endcode
//! [clang format]
