Uncrustify (1) Linux Manual Page

NAME

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

SYNOPSIS

uncrustify [OPTIONS] [FILES]

DESCRIPTION

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

OPTIONS

Basic Options:

-c CFG: Use the config file CFG.
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)

Config/Help Options:

-h -? –help –usage: Print this message and exit
–version: Print the version 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.

Debug Options:

-p FILE: Dump debug info to a 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

EXAMPLES

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]")

NOTES

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