Post any bugs to the issue tracker found on the project's GitHub page: https://github.com/uncrustify/uncrustify/issues
Please include the following with your issue: - a description of what is not working right - input code sufficient to demonstrate the issue - expected output code - configuration options used to generate the output
If the issue cannot be easily reproduced, then it isn't likely to be fixed.
CMake is a tool that generates build systems (Makefiles, Visual Studio project files, and others).
To generate a build system for Uncrustify using CMake, create a build folder and run CMake from it:
$ mkdir build
$ cd build
$ cmake ..
Then use the build tools of your build system (in many cases this will simply
make, but on Windows it could be MSBuild or Visual Studio). Or use CMake
to invoke it:
$ cmake --build .
If testing is enabled, CMake generates a
test target, which you can build
using your build system tools (usually
make test). This can also be invoked
$ ctest -V -C Debug
There is also an
install target, which can be used to install the Uncrustify
Some build systems are single-configuration, which means you specify the build
type when running CMake (by setting the
CMAKE_BUILD_TYPE variable), and the
generated files then build that configuration.
An example of a single-configuration build system is Makefiles. You can build the Release configuration of Uncrustify (from the build folder) with:
$ cmake -DCMAKE_BUILD_TYPE=Release ..
Other build systems are multi-configuration, which means you specify the build type when building.
An example of a multi-configuration build system is Visual Studio project
files. When you open the project in Visual Studio, you can select which
configuration to build. You can also do this while building from the command
cmake --build . --config Release.
The executable is src/uncrustify. Copy that to your ~/bin/ folder or wherever you want.
You can of course just open the Xcode project and build uncrustify using the default 'Debug' configuration but if you want to install it the 'Install' configuration will not work from within Xcode.
For that you will have to use the Xcode command line tool 'xcodebuild'.
To do that, cd into the uncrustify project folder where uncrustify.xcodeproj resides and enter the following command:
$ sudo xcodebuild -configuration 'Install'
You will be prompted for the root level password. By doing this you will install uncrustify into /usr/local/bin. The install location can be changed by editing the Build Settings for the uncrustify target. The setting you need to change is called, surprisingly enough, 'Installation Directory'.
Examine the example config files in
etc (such as ben.cfg)
and/or read configuration.txt.
Copy the existing config file that closely matches your style and put in
~/.uncrustify/. Find complete configuration file options
in this file. Modify to your
As of the current release, I don't particularly trust this program to not make mistakes and screw up my whitespace formatting.
Here's how to run it:
$ uncrustify -c ~/.uncrustify/mystyle.cfg -f somefile.c > somefile.c.unc
The -c option selects the configuration file. The -f option specifies the input file. The output is sent to stdout. Error messages are sent to stderr.
Use a quality side-by-side diff tool to determine if the program did what you wanted. Repeat until your style is refined.
Write a script to automate the above. Check out etc/dofiles.sh for an example. That script is used as follows:
$ find myproj -name "*.[ch]" > files.txt
$ sh etc/dofiles.sh files.txt
$ xxdiff out/myproj myproj
