UNCRUSTIFY(1) User Commands UNCRUSTIFY(1)

uncrustify - C, C++, C#, D, Java and Pawn source code beautifier

uncrustify [OPTIONS] [FILES]

If no input files are specified, the input is read from stdin.
If reading from stdin, you should specify the language using -l.

If -F is used or files are specified on the command line, the output filename is PFX + "/" + filename + SFX.
Unless, of course, the options --replace or --no-backup are used.

When reading from stdin or doing a single file via the '-f' option, the output is dumped to stdout, unless redirected with -o FILE.

Errors are always dumped to stderr

-c CFG
Use the config file CFG, or defaults if CFG is set to '-'.
If not specified, uncrustify will use $UNCRUSTIFY_CONFIG or $HOME/.uncrustify.cfg.
-f FILE
Process the single file FILE, sending output to stdout or the file specified with -o.
-o FILE
Redirect output to FILE.
Use with -f, --update-config, --update-config-with-doc, --universalindent.
--check
Do not output the new text, instead verify that nothing changes when the file(s) are processed. The status of every file is printed to stderr. The exit code is EXIT_SUCCESS if there were no changes, EXIT_FAILURE otherwise.
-F FILE
Read files to process from FILE, one filename per line. If FILE is ´-´ then read filenames from standard input instead of a file.
You can create this file using something like ´find . -name "*.c" > list.txt´.
This cannot be combined with -f.
--prefix PFX
Prepend PFX to the output filename path.
This cannot be combined with -f, --replace, or --no-backup.
--suffix SFX
Append SFX to the output filename.
The default is '.uncrustify' if neither SFX or PFX are specified.
This cannot be combined with -f, --replace, or --no-backup.
--frag
Assume the input is a code fragment and the first line is properly indented.
--replace
Replace source files (creates a backup).
This cannot be combined with -f, --prefix, or --suffix.
--no-backup
Replace files, no backup. Useful if files are under source control
This cannot be combined with -f, --prefix, or --suffix.
--mtime
Preserve mtime on replaced files.
-l
Language override: C, CPP, D, CS, JAVA, PAWN, VALA, OC, OC+
-t
Load a file with types (usually not needed)
-q
Quiet mode - no output on stderr (-L will override)

-h -? --help --usage
Print this message and exit
--version
Print the version and exit
--count-options
Print the number of available options and exit
--show-config
Print out option documentation and exit
--update-config
Output a new config file.
--update-config-with-doc
Output a new config file with embedded usage comments.
--universalindent
Output a config file for Universal Indent GUI.
--detect
Detects the config from a source file. Use with '-f FILE'. Detection is currently fairly limited.

-p FILE
Dump debug info into FILE, or to stdout if FILE is set to '-'.
Must be used in combination with '-f FILE'.
-ds FILE --dump-steps FILE
Dump parsing info at various moments of the formatting process.
This creates a series of files named 'FILE_nnn.log', each
corresponding to a formatting step in uncrustify.
The file 'FILE_000.log' lists the formatting options in use.
Must be used in combination with '-f FILE'.
-L SEV
Set the log severity (see log_levels.h)
-s
Show the log severity in the logs
--decode FLAG
Print FLAG as text and exit

Read a D file from stdin, output to stdout.
cat foo.d | uncrustify -q -c my.cfg -l d
Process a file, output to stdout.
uncrustify -c my.cfg -d foo.d
Process a source tree, output to a different tree.
find src -name "*.[ch]" > files.txt
uncrustify -c my.cfg -F files.txt --prefix out
Process a source tree in‐place.
uncrustify -c my.cfg --no-backup $(find src -name "*.[ch]")

Use comments containing ' *INDENT-OFF*' and ' *INDENT-ON*' to disable processing of parts of the source file.
