* Adding Samples directory with mcat Sample (changed main
Makefile but didn't add to the SUBDIRS)
* Mono.GetOptions/Options.cs, Mono.GetOptions/OptionList
An overrideable DefaultArgumentProcessor was added to
base class Options that just collects them
to the string RemainingArguments property as before.
It is a virtual method, but it can also be
overriden by another method tagged with the
ArgumentProcessorAttribute in the derived class
to stay binary compatible with old code.
* Added Mono.GetOptions/KillOptionAttribute.cs
This new attribute permit to hide (kill) an inherited
option when overriding the virtual base member.
* Added Mono/AdditionalInfoAttribute.cs
This new attribute permit to add some extra text at
the end of the automatically generated help screen
* Added Mono/ReportBugsToAttribute.cs
This new attribute adds a "Report bugs to <Url>"
message at the end of the automatically generated help screen
Sample run from sample mcat.exe:
[rafael at fedora Samples]$ mono mcat.exe -A first second third
This is just a simulation of a cat-like program.
The command line options where processed by Mono.GetOptions and resulted as:
ShowTabs = True
ShowLineEnds = True
ShowNonPrinting = True
NumberNonBlank = False
NumberAllLines = False
SqueezeBlankLines = False
RunningOnWindows = False
Would be copying these files to stdout: first, second, third
Follows help screen
mcat 22.214.171.124 - (c)2005 Rafael Teixeira
Simulated cat-like program
Usage: mcat [options] [FILE]...
Concatenate FILE(s), or standard input, to standard output.
-A --show-all equivalent to -vET
-b --number-nonblank number nonblank output lines
-e equivalent to -vE
-E --show-ends display $ at end of each line
-n --number number all output lines
-s --squeeze-blank never more than one single blank line
-t equivalent to -vT
-T --show-tabs display TAB characters as ^I
-v --show-nonprinting use ^ and M- notation, except for LFD and TAB
--help display this help and exit
--version output version information and exit
With no FILE, or when FILE is -, read standard input.
Please report bugs to <rafaelteixeirabr at hotmail.com>
Compare the help-screen part to what 'cat --help' returns
