UNCRUSTIFY(1)							   User Commands						     UNCRUSTIFY(1)

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. -F FILE Read files to process from FILE, one filename per line. 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. AUTHOR
