NAME
       patchview - Without options, show numbered files modified by the patch. With options, behave as filterdiff.

SYNOPSIS

       patchview [[-n] | [--line-number]] [[-p n] | [--strip-match=n]] [--strip=n] [--addprefix=PREFIX] [[-s] | [--status]]
		 [[-E] | [--empty-files-as-removed]] [[-i PATTERN] | [--include=PATTERN]] [[-x PATTERN] |
		 [--exclude=PATTERN]] [[-z] | [--decompress]] [[-# RANGE] | [--hunks=RANGE]] [--lines=RANGE] [[-FRANGE] |
		 [--files=RANGE]] [[-H] | [--with-filename]] [[-h] | [--no-filename]] [[-v] | [--verbose]...] [file...]

       patchview {[--help] | [--version] | [--filter ...] | [--grep ...]}

DESCRIPTION
       So what is patchview? It is a wrapper of filterdiff for use with numbered files.

	   patchview

       (without args) is equivalent to: lsdiff --number

	   patchview -F2-

       (or with any other args) is equivalent to: filterdiff -F2- (or whatever arguments are supplied)

       There are two scripts for working with git (gitdiff and gitdiffview) and two for svn (svndiff and svndiffview).

	   svndiff

	   gitdiff

       (without args) will give the list of files modified

	   svndiff -F1

	   gitdiff -F1

       will show the patch of file #1

	   svndiffview

	   gitdiffview

       pipe all patches through filterdiff to vim - -R (in read-only mode, easy to quit), showing complete patch with color.

	   svndiffview -F2

	   gitdiffview -F2

       (or any other args) will pipe patch of file #2 to vim - -R

OPTIONS
       -n, --line-number
	   Display the line number that each patch begins at. If verbose output is requested (using -nv), each hunk of each
	   patch is listed as well.

	   For each file that is modified, a line is generated containing the line number of the beginning of the patch,
	   followed by a Tab character, followed by the name of the file that is modified. If -v is given once, following
	   each of these lines will be one line for each hunk, consisting of a Tab character, the line number that the hunk
	   begins at, another Tab character, the string “Hunk #”, and the hunk number (starting at 1).

	   If the -v is given twice in conjunction with -n (i.e.  -nvv), the format is slightly different: hunk-level
	   descriptive text is shown after each hunk number, and the --number-files option is enabled.

       -N, --number-files
	   File numbers are listed, beginning at 1, before each filename.

       -# RANGE, --hunks=RANGE
	   Only list hunks within the specified RANGE. Hunks are numbered from 1, and the range is a comma-separated list of
	   numbers or “first-last” spans, optionally preceded by a modifier 'x' which inverts the entire range; either the
	   first or the last in the span may be omitted to indicate no limit in that direction.

       --lines=RANGE
	   Only list hunks that contain lines from the original file that lie within the specified RANGE. Lines are numbered
	   from 1, and the range is a comma-separated list of numbers or “first-last” spans, optionally preceded by a
	   modifier 'x' which inverts the entire range; either the first or the last in the span may be omitted to indicate
	   no limit in that direction.

       -F=RANGE, --files=RANGE
	   Only list files indicated by the specified RANGE. Files are numbered from 1 in the order they appear in the patch
	   input, and the range is a comma-separated list of numbers or “first-last” spans, optionally preceded by a
	   modifier 'x' which inverts the entire range; either the first or the last in the span may be omitted to indicate
	   no limit in that direction.

       -p n, --strip-match=n
	   When matching, ignore the first n components of the pathname.

       --strip=n
	   Remove the first n components of the pathname before displaying it.

       --addprefix=PREFIX
	   Prefix the pathname with PREFIX before displaying it.

       -s, --status
	   Show file additions, modifications and removals. A file addition is indicated by a “+”, a removal by a “-”, and a
	   modification by a “!”.

       -E, --empty-files-as-removed
	   Treat empty files as absent for the purpose of displaying file additions, modifications and removals.

       -i PATTERN, --include=PATTERN
	   Include only files matching PATTERN.

       -x PATTERN, --exclude=PATTERN
	   Exclude files matching PATTERN.

       -z, --decompress
	   Decompress files with extensions .gz and .bz2.

       -H, --with-filename
	   Print the name of the patch file containing each patch.

       -h, --no-filename
	   Suppress the name of the patch file containing each patch.

       -v, --verbose
	   Verbose output.

       --help
	   Display a short usage message.

       --version
	   Display the version number of patchview.

       --filter
	   Behave like filterdiff(1) instead.

       --grep
	   Behave like grepdiff(1) instead.

EXAMPLES
       We can make the following one-line script with the name difftotrunk.sh, to view the differences of two directories or
       svn repos (trunk and .)

	   diff ../trunk . -ru -x .svn | patchview "$@"

	   ./difftotrunk.sh , will show all different files and his number.

	   ./difftotrunk.sh -F3,4 , will show the differences of files #3 and #4 only.

	   ./difftotrunk.sh -F3 -#1 , will show only hunk #1 of file #3.

	   ./difftotrunk.sh -F3 -#x1 , will show the differences of files #3 without hunk #1 (x means that exclude).
