uncrustify(1)

Basic Options:

-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.

--if-changed

Write to stdout (or create output FILE) only if a change was detected.

--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)

Config/Help Options:

-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.

--tracking space:FILE

Prepare space tracking information for debugging.

--tracking nl:FILE

Prepare newline tracking information for debugging.

--tracking start:FILE

Prepare start of statement tracking information for debugging. Cannot be used with the -o option.

Debug Options:

-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
