I built latest Git master (e9b77c84a0) which has `rp/apply-cached-with-i-t-a` and tested this patch. It works... for the most part. I can select a line set of lines and they get staged/unstaged, which is good. The part that is not good though is that a lot of common operations still don't work as they should: - I can't click on the icon in the "Unstaged Changes" pane to stage the whole file. Nothing happens when I do that. - The file that is marked as intent-to-add shows up in both the "Staged Changes" and "Unstaged Changes" panes, with the "Staged Changes" part being empty. Ideally it should only show up in the "Unstaged Changes" pane. - Selecting the whole file and choosing "Stage Lines for Commit" works well. But choosing "Stage Hunk for Commit" does not. While the changes do get staged, the UI is not properly updated and the file is still listed in the "Unstaged Changes" pane. I think the difference here is because for `apply_or_revert_range_or_line`, we call `do_rescan` after it to update the UI, but for `apply_or_revert_hunk` we update the UI "manually" in the function after we are done applying or reverting the changes. So the logic to update the UI needs to be updated to account for this change. Or we can get rid of all that logic and just run a rescan. And also, like you mentioned, we don't retain the i-t-a state when unstaging. But with some quick testing, I see that Git command line doesn't either (I tried a plain `git restore --staged`). So IMO we should mimic what the command line UI does and not retain the i-t-a state when unstaging. > > Thoughts? IMO this is a good start but more work needs to be done before we can call this feature finished. > Published-As: https://github.com/gitgitgadget/git/releases/tag/pr-699%2Fdscho%2Fgit-gui-stage-ita-hunks-and-lines-v1 > Fetch-It-Via: git fetch https://github.com/gitgitgadget/git pr-699/dscho/git-gui-stage-ita-hunks-and-lines-v1 > Pull-Request: https://github.com/gitgitgadget/git/pull/699 > > git-gui.sh | 2 ++ > lib/diff.tcl | 12 ++++++++---- > 2 files changed, 10 insertions(+), 4 deletions(-) > > diff --git a/git-gui.sh b/git-gui.sh > index 49bd86e635..e08cb17395 100755 > --- a/git-gui.sh > +++ b/git-gui.sh > @@ -2080,6 +2080,7 @@ set all_icons(U$ui_index) file_merge > set all_icons(T$ui_index) file_statechange > > set all_icons(_$ui_workdir) file_plain > +set all_icons(A$ui_workdir) file_plain > set all_icons(M$ui_workdir) file_mod > set all_icons(D$ui_workdir) file_question > set all_icons(U$ui_workdir) file_merge > @@ -2106,6 +2107,7 @@ foreach i { > {A_ {mc "Staged for commit"}} > {AM {mc "Portions staged for commit"}} > {AD {mc "Staged for commit, missing"}} > + {AA {mc "Intended to be added"}} > > {_D {mc "Missing"}} > {D_ {mc "Staged for removal"}} > diff --git a/lib/diff.tcl b/lib/diff.tcl > index 871ad488c2..36d3715f7b 100644 > --- a/lib/diff.tcl > +++ b/lib/diff.tcl > @@ -582,7 +582,8 @@ proc apply_or_revert_hunk {x y revert} { > if {$current_diff_side eq $ui_index} { > set failed_msg [mc "Failed to unstage selected hunk."] > lappend apply_cmd --reverse --cached > - if {[string index $mi 0] ne {M}} { > + set file_state [string index $mi 0] > + if {$file_state ne {M} && $file_state ne {A}} { > unlock_index > return > } > @@ -595,7 +596,8 @@ proc apply_or_revert_hunk {x y revert} { > lappend apply_cmd --cached > } > > - if {[string index $mi 1] ne {M}} { > + set file_state [string index $mi 1] > + if {$file_state ne {M} && $file_state ne {A}} { > unlock_index > return > } > @@ -687,7 +689,8 @@ proc apply_or_revert_range_or_line {x y revert} { > set failed_msg [mc "Failed to unstage selected line."] > set to_context {+} > lappend apply_cmd --reverse --cached > - if {[string index $mi 0] ne {M}} { > + set file_state [string index $mi 0] > + if {$file_state ne {M} && $file_state ne {A}} { > unlock_index > return > } > @@ -702,7 +705,8 @@ proc apply_or_revert_range_or_line {x y revert} { > lappend apply_cmd --cached > } > > - if {[string index $mi 1] ne {M}} { > + set file_state [string index $mi 1] > + if {$file_state ne {M} && $file_state ne {A}} { > unlock_index > return > } > These changes look good to me to set up basic functionality.
