NAMEpatchview − Without options, show numbered files modified by the patch​. With options, behave as filterdiff​.

SYNOPSISpatchview [[−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 ​.​.​.]}

DESCRIPTIONSo 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)​. svndiffgitdiff(without args) will give the list of files modified svndiff −F1gitdiff −F1will show the patch of file #1 svndiffviewgitdiffviewpipe all patches through filterdiff to vim − −R (in read−only mode, easy to quit), showing complete patch with color​. svndiffview −F2gitdiffview −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​.

EXAMPLESWe 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)​.
