[Heiko Voigt]

This is useful if a user wants to checkout a file from a certain
commit. This is equivalent to

  git checkout $commit $file

It looks like the existing msgid/msgstr pairs have line number
comments. Why not add that for the new strings? Presumably it might
inflate the patch a lot though, as old strings get displaced.

I was wondering what these numbers were for. Now it makes sense. I am
not against doing it but I would need a script to update the existing
ones. Is there something like that? Otherwise I would just add the line
number for the two new msgs.

Cheers Heiko

You should update PO files with the msgmerge(1) program, the ab/i18n
branch has docs on how to do that in po/README.

But as Michele points out you probably shouldn't update these, some
projects do, but it probably makes more sense to leave these updates
up to translators.

Here is an updated version of that patch without the po changes.

You shouldn't change anything under po/ (unless you want to actually translate
something, of course): translators will do it for you. There would be less
of a chance of a conflicting merge.

Thanks for the patch.  However, the commit message doesn't mention
that the patch also adds the 'checkout from parent' menu item or why
that's a useful thing to have.  I like the 'checkout from this commit'
thing but I don't immediately see why checking out from the first
parent is so useful that we have to have it as a menu item, but
checking out from other parents of a merge isn't.

Also, don't bother updating the po files.  The translators generally
prefer it if we don't.

Paul.

[PATCH v3] gitk: add menuitem for file checkout from this or parent commit

[hvoigt]

This is useful if a user wants to checkout a file from a certain
commit. This is equivalent to

  git checkout $commit $file

and

  git checkout $commit^ $file

Checkout of the first parent is useful in situations where you want to
checkout a file before some modification. In the patch view only the
modified filenames are shown. It is much quicker to select the commit
which modified the file and then choose the file from the patch view
compared to select the parent commit and then browse through the whole
tree to choose the file.

Here is a new version of the patch with some added explanation why this
is useful in day to day use. I choose the first parent because in my
usecase I checkout single files by typically using non-merge commits.
Do you think there are usecases for second or other parent commits on
merge commits?

Cheers Heiko
