Hello William, please ignore my modification for they are just for learing/testing purposes

SREP (Search and REPlace)

Search and REPlace tool that is smaller
and easier to use than grep/sed for
file or stream processing.

By default it will search in the same manner as fgrep;
and when pattern matching is needed, it make use
of PAMSYN (see pamsyn.README) which is an easier
and more powerful alternive to RegExp.


To build:
make && make install


Usage: srep [OPTIONS] pattern [FILES]

	The pattern is searched on stdin if no files is given as argument.

Options:

 -a	Alternate behavior that show only the parts
	of a line that matches; and when doing
	substitution, the entire line containing
	the match is substituted.

 -b	Binary files are treated as text files.
	When doing substitution, binary files
	are skipped unless this option is used.

 -c	Turn on coloring.

 -e PAMSYN
	Return the pamsyn with all metacharacters escaped.
	The pamsyn is taken from stdin if no argument is given.

 -h	Display this help.

 -i	ignore characters' case.

 -k	Do not skip symbolic links to file.

 -l	Prefix each line of output with its line number
	Ignored when doing substitution.

 -n COUNT
	Only output COUNT matches from each given file,
	or only do COUNT substitutions.

 -N COUNT_ABOVE_AND_BELOW
 -N COUNT_ABOVE,COUNT_BELOW
	Number of context lines to display
	above and/or below the line
	where a match was found.
	Ignored when doing substitution
	or when option -a is used.

 -p	The given search pattern is a pamsyn.

 -r 	Recursively process files in directories and subdirectories.

 -R 	Recursively process files in directories and subdirectories,
	following symbolic links.

 -s SUBSTITUTE
	Substitute the match with SUBSTITUTE in each file
	given as argument. If the input is stdin or given
	through the option -t, the output goes to stdout.
	More than one option -s can be used when using a pamsyn;
	for each portion of a match, there has to be a corresponding
	option -s, otherwise nothing is substituted for that
	particular portion of the match.
	ei: Two option -s can be used to surround the word "this"
	wherever it will be found, using the pamsyn ".#{this}." .
	In the above example, there are two portions in the match:
	before and after the word "this"; so for each portion
	of the match, there has to be a corresponding option -s,
	otherwise nothing is substituted for that particular
	portion of the match.
	If the option -a is used, more than one option -s
	is useless; the additional option -s are ignored
	and all portions of a match are substituted
	using the same option -s.
	When found in the option -s argument,
	the following escape sequences are interpreted:
	'\n': Newline.
	'\t': Tab.
	'\xx': Where xx is a two digits hexadecimal
		number that translate to a byte value.
	'\\': Escape the character '\' which
		is used for escaping.

 -t TEXT
	The pattern is searched on TEXT instead
	of stdin or files given as arguments.

 -x PATH
	Exclude paths ending with PATH.
	More than one -x can be given.

 -X PATHPAMSYN
	Exclude paths for which the ending
	match the pamsyn PATHPAMSYN.
	More than one -X can be given.
