decomet - remove comments and multiple blank lines from code, fast cmd line c executable

decomet is a cosmic fast Windows command line tool that will minify source code. By default this will remove all comment lines starting with // or contained  with /**/. 

It features;

1. remove all blank/empty lines. Blank is defined as whitespace* 
2. remove all Unicode control characters, except tab, form feed and carriage return.
3. remove empty duplicate lines reduce them to 1 line for readability of code.
4. remove indent whitespace*
5. minify and normalize whitespace* to a single space
6. prefix with line number. Specifically line number, tab and then line  
7. recurses sub-directories
8. funnel to a single output directory
9. added datetime stamp to output filename *udpate as of Mon 10-Jun-24 2:57pm EDT

*ISO 30112 defines POSIX whitespace characters for function iswspace() for locale 'en_US.UTF8' as Unicode characters U+0009..U+000D, U+0020, U+1680, U+180E, U+2000..U+2006, U+2008..U+200A, U+2028, U+2029, U+205F, and U+3000
  
It super fast and written in C/C++ mixture.
It reads and writes UTF-8 source code. 
Files accept Unicode names. 
Built-in human readable elapsed time.

The code base for this project is http://code.google.com/p/cpp-decomment/ but has been greatly improved to handle Unicode spaces, control characters, UTF-8 files and UTF-8 filename. Moreover, the state machine has been optimized and improved to work.
Improved code to make sure all the switches actually work.

As with all my software - 100% no malware or spyware. I am trying to sell this and that would be a bad idea.

decomet -h 2> help.txt - to pipe to a file 'help.txt' 

Usage:  decomet -[bcehimnprsv] [-d<DIR>] file1.c file2.js ...
Outputs (adds extension .dec.{org ext})  file1.c.dec.c file2.js.dec.js ...
Decomment source files, optionally remove whitespace, control characters and duplicate 
empty lines 

  -b         remove all whitespace* blank/empty lines
  -c         preprocess & remove control characters in ASCII and UNicode range
             U+0001..U+0008, U+000E..U+001F and U+007F..U+009F, respectively.
             NOTE: U+001A 'SUB' Substitute character will terminate reading a text file 
unexpectedly. 
  -e         Removes duplicate Unicode whitespace* entire lines aka 'empty lines', leaving 
1 line. 
             *ISO 30112 defines POSIX whitespace characters for function iswspace() for 
locale 'en_US.UTF8' as Unicode characters 
             U+0009..U+000D, U+0020, U+1680, U+180E, U+2000..U+2006, U+2008..U+200A, 
U+2028, U+2029, U+205F, and U+3000 
  -h         display help message
  -i         remove indent whitespace*
  -m         minify && normalize whitespace* to a single space
  -n         prefix with line number
  -p         preview files matching wildcard for recursive search
  -r         recursive search sub-dirs under the input-file's folder - file wildcard needed
  -s         output to stdout, instead of output-files (infile1.c.dec.c)
  -t         add datetime to output. Example: infile1.c.dec_10Jun24_1347PM.c
  -v         switch off verbose - default on

  -d<DIR>    output funnel directory, no space after -d

  file[*?].c input-files, file wildcard [?*] allowed. The output-file is 'filexxx.c.dec.c'

Features:

        Fast, written in mainly C, C++ for Unicode support
        Read and writes UTF-8 text files
        Implements a state machine for parsing to remove comments, enforce min. spaces, etc.
        Implements a stack for file/folder traversal

Limitations:

        Each line length is a max of 100,000 characters wide
        Does not handle long file paths (>260)

Notes:

        org src code - http://code.google.com/p/cpp-decomment/
        improved to handle Unicode, UTF-8 files && remove duplicate lines, Unicode 
whitespace 
        fixed stack imp (org. failed if single double quote found with -m switch)
        improved to assure all switches work correctly, etc.
