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 4 scripts for working with git repos (gitdiff, gitdiffview,
gitshow and gitshowview) and 2 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
gitshow
gitshowview
This is the same as gitdiff but uses git show instead of git diff.
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.
-pn, --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.
--git-prefixes=strip|keep
How to handle a/ and b/ prefixes in Git diff filenames. With strip,
removes the prefixes both for filename matching (when using -i and
-x options) and for filename output (similar to --strip). With keep
(default), preserves existing behavior. Applies to both
Git-specific diffs (binary files, renames, mode changes) and
traditional diffs when part of a Git patch. Note: With keep, copy
and rename operations are treated as if they had a/ and b/ prefixes
for consistency with other Git operations. The default will change
to strip in version 0.5.0.
--git-extended-diffs=exclude|include
Controls whether to process Git diffs without traditional content
hunks. This includes renames, copies, mode-only changes, and binary
files. With exclude (default in 0.4.x), these diffs are skipped.
With include (default in 0.5.0+), these diffs are processed
normally. This option affects file numbering with -N and file
filtering with -F.
--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
"!".
--empty-files-as-absent, --empty-files-as-removed
Treat empty files as absent for the purpose of displaying file
additions, modifications and removals. For example, a file with an
empty old version and additions in the new version will be treated
as a file addition (+) rather than a modification (!). Note: For
grepdiff, only the long form is available (-E means
--extended-regexp for grepdiff).
-iPATTERN, --include=PATTERN
Include only files matching PATTERN.
-xPATTERN, --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. For the git and svn wrapper scripts (gitdiff,
gitdiffview, gitshow, gitshowview, svndiff, svndiffview), this
option shows the full command that is being executed.
--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).
