When we are on a detached head - since gitk does not display where we are - reset has no sense, so disable the relevant line on the context menu, and point out to the user that we are on a detached head. Otherwise, a reset from gitk when on a detached head returns the error: can't read "headids()": no such element in array can't read "headids()": no such element in array while executing "removehead $headids($name) $name" (procedure "movehead" line 4) invoked from within "movehead $newhead $mainhead" (procedure "readresetstat" line 20) invoked from within "readresetstat file4" ("eval" body line 1) invoked from within "eval $script" (procedure "dorunq" line 9) invoked from within "dorunq" ("after" script) Signed-off-by: Michele Ballabio <barra_cuda@xxxxxxxxxxxx> --- On Friday 02 May 2008, Michele Ballabio wrote: > On Friday 02 May 2008, Paul Mackerras wrote: > > I wonder if we can make this message something more appropriate than > > "Reset branch to here" (since $mainhead has to be the empty string > > here)?
