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).
