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.

grepdiff(1)
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).
