Use the newly added 'diff --word-diff=porcelain' to teach gitk a color-words mode, with two different modes analogous to the --word-diff=plain and --word-diff=color settings. These are selected by a dropdown box. As an extra twist, automatically enable this word-diff support when the user mentions a word-diff related option on the command line. These options were previously ignored because they would break diff parsing. Both of these features are only enabled if we have a version of git that supports --word-diff=porcelain, meaning at least 1.7.2. Signed-off-by: Thomas Rast <trast@xxxxxxxxxxxxxxx> --- I sent this out ages ago, but it seems to have got stuck waiting for git.git to pick up the required support: http://mid.gmane.org/20100417063557.GB6681@xxxxxxxxxxxxxxxxxxxx Then I also forgot. As you can check with 'git tag --contains 882749a', this support has indeed gone into 1.7.2, so gitk can now also learn about word-diff. The only change since the patch discussed in the above thread is that I resolved a conflict with current gitk.git, and that the commit message now knows the exact version that first had the porcelain word-diff. (I hand-edited the patch to apply to gitk.git, so if that broke anything it's my fault. But it seems to apply okay to its current master.) gitk | 64 ++++++++++++++++++++++++++++++++++++++++++++++++++++++-- 1 files changed, 61 insertions(+), 3 deletions(-) diff --git a/gitk b/gitk index 1b0e09a..63a90bc 100644 --- a/gitk +++ b/gitk @@ -131,6 +131,7 @@ proc unmerged_files {files} { proc parseviewargs {n arglist} { global vdatemode vmergeonly vflags vdflags vrevs vfiltered vorigargs env + global worddiff git_version set vdatemode($n) 0 set vmergeonly($n) 0 @@ -168,7 +169,7 @@ proc parseviewargs {n arglist} { lappend diffargs $arg } "--raw" - "--patch-with-raw" - "--patch-with-stat" - - "--name-only" - "--name-status" - "--color" - "--color-words" - + "--name-only" - "--name-status" - "--color" - "--log-size" - "--pretty=*" - "--decorate" - "--abbrev-commit" - "--cc" - "-z" - "--header" - "--parents" - "--boundary" - "--no-color" - "-g" - "--walk-reflogs" - "--no-walk" - @@ -177,6 +178,18 @@ proc parseviewargs {n arglist} { # These cause our parsing of git log's output to fail, or else # they're options we want to set ourselves, so ignore them. } + "--color-words*" - "--word-diff=color" { + # These trigger a word diff in the console interface, + # so help the user by enabling our own support + if {[package vcompare $git_version "1.7.2"] >= 0} { + set worddiff [mc "Color words"] + } + } + "--word-diff*" { + if {[package vcompare $git_version "1.7.2"] >= 0} { + set worddiff [mc "Markup words"] + } + } "--stat=*" - "--numstat" - "--shortstat" - "--summary" - "--check" - "--exit-code" - "--quiet" - "--topo-order" - "--full-history" - "--dense" - "--sparse" - @@ -1970,6 +1983,8 @@ proc makewindow {} { global fprogitem fprogcoord lastprogupdate progupdatepending global rprogitem rprogcoord rownumsel numcommits global have_tk85 use_ttk NS + global git_version + global worddiff # The "mc" arguments here are purely so that xgettext # sees the following string as needing to be translated @@ -2243,6 +2258,15 @@ proc makewindow {} { ${NS}::checkbutton .bleft.mid.ignspace -text [mc "Ignore space change"] \ -command changeignorespace -variable ignorespace pack .bleft.mid.ignspace -side left -padx 5 + + set worddiff [mc "Line diff"] + if {[package vcompare $git_version "1.7.2"] >= 0} { + makedroplist .bleft.mid.worddiff worddiff [mc "Line diff"] \ + [mc "Markup words"] [mc "Color words"] + trace add variable worddiff write changeworddiff + pack .bleft.mid.worddiff -side left -padx 5 + } + set ctext .bleft.bottom.ctext text $ctext -background $bgcolor -foreground $fgcolor \ -state disabled -font textfont \ @@ -7502,11 +7526,16 @@ proc changeignorespace {} { reselectline } +proc changeworddiff {name ix op} { + reselectline +} + proc getblobdiffs {ids} { global blobdifffd diffids env global diffinhdr treediffs global diffcontext global ignorespace + global worddiff global limitdiffs vfilelimit curview global diffencoding targetline diffnparents global git_version currdiffsubmod @@ -7523,6 +7552,9 @@ proc getblobdiffs {ids} { if {$ignorespace} { append cmd " -w" } + if {$worddiff ne [mc "Line diff"]} { + append cmd " --word-diff=porcelain" + } if {$limitdiffs && $vfilelimit($curview) ne {}} { set cmd [concat $cmd -- $vfilelimit($curview)] } @@ -7608,6 +7640,7 @@ proc getblobdiffline {bdf ids} { global ctext_file_names ctext_file_lines global diffinhdr treediffs mergemax diffnparents global diffencoding jump_to_here targetline diffline currdiffsubmod + global worddiff set nr 0 $ctext conf -state normal @@ -7747,15 +7780,28 @@ proc getblobdiffline {bdf ids} { # parse the prefix - one ' ', '-' or '+' for each parent set prefix [string range $line 0 [expr {$diffnparents - 1}]] set tag [expr {$diffnparents > 1?
