|

|
||||
Interactive mode
|
||||
----------------
|
||||
When the command enters the interactive mode, it shows the
|
||||
output of the 'status' subcommand, and then goes into ints
|
||||
interactive command loop.
|
||||
|
||||
The command loop shows the list of subcommands available, and
|
||||
gives a prompt "What now> ". In general, when the prompt ends
|
||||
with a single '>', you can pick only one of the choices given
|
||||
and type return, like this:
|
||||
|
||||
------------
|
||||
*** Commands ***
|
||||
1: status 2: update 3: revert 4: add untracked
|
||||
5: patch 6: diff 7: quit 8: help
|
||||
What now> 1
|
||||
------------
|
||||
|
||||
You also could say "s" or "sta" or "status" above as long as the
|
||||
choice is unique.
|
||||
|
||||
The main command loop has 6 subcommands (plus help and quit).
|
||||
|
||||
status::
|
||||
|
||||
This shows the change between HEAD and index (i.e. what will be
|
||||
committed if you say "git commit"), and between index and
|
||||
working tree files (i.e. what you could stage further before
|
||||
"git commit" using "git-add") for each path. A sample output
|
||||
looks like this:
|
||||
+
|
||||
------------
|
||||
staged unstaged path
|
||||
1: binary nothing foo.png
|
||||
2: +403/-35 +1/-1 git-add--interactive.perl
|
||||
------------
|
||||
+
|
||||
It shows that foo.png has differences from HEAD (but that is
|
||||
binary so line count cannot be shown) and there is no
|
||||
difference between indexed copy and the working tree
|
||||
version (if the working tree version were also different,
|
||||
'binary' would have been shown in place of 'nothing'). The
|
||||
other file, git-add--interactive.perl, has 403 lines added
|
||||
and 35 lines deleted if you commit what is in the index, but
|
||||
working tree file has further modifications (one addition and
|
||||
one deletion).
|
||||
|
||||
update::
|
||||
|
||||
This shows the status information and gives prompt
|
||||
"Update>>". When the prompt ends with double '>>', you can
|
||||
make more than one selection, concatenated with whitespace or
|
||||
comma. Also you can say ranges. E.g. "2-5 7,9" to choose
|
||||
2,3,4,5,7,9 from the list. You can say '*' to choose
|
||||
everything.
|
||||
+
|
||||
What you chose are then highlighted with '*',
|
||||
like this:
|
||||
+
|
||||
------------
|
||||
staged unstaged path
|
||||
1: binary nothing foo.png
|
||||
* 2: +403/-35 +1/-1 git-add--interactive.perl
|
||||
------------
|
||||
+
|
||||
To remove selection, prefix the input with `-`
|
||||
like this:
|
||||
+
|
||||
------------
|
||||
Update>> -2
|
||||
------------
|
||||
+
|
||||
After making the selection, answer with an empty line to stage the
|
||||
contents of working tree files for selected paths in the index.
|
||||
|
||||
revert::
|
||||
|
||||
This has a very similar UI to 'update', and the staged
|
||||
information for selected paths are reverted to that of the
|
||||
HEAD version. Reverting new paths makes them untracked.
|
||||
|
||||
add untracked::
|
||||
|
||||
This has a very similar UI to 'update' and
|
||||
'revert', and lets you add untracked paths to the index.
|
||||
|
||||
patch::
|
||||
|
||||
This lets you choose one path out of 'status' like selection.
|
||||
After choosing the path, it presents diff between the index
|
||||
and the working tree file and asks you if you want to stage
|
||||
the change of each hunk. You can say:
|
||||
|
||||
y - add the change from that hunk to index
|
||||
n - do not add the change from that hunk to index
|
||||
a - add the change from that hunk and all the rest to index
|
||||
d - do not the change from that hunk nor any of the rest to index
|
||||
j - do not decide on this hunk now, and view the next
|
||||
undecided hunk
|
||||
J - do not decide on this hunk now, and view the next hunk
|
||||
k - do not decide on this hunk now, and view the previous
|
||||
undecided hunk
|
||||
K - do not decide on this hunk now, and view the previous hunk
|
||||
+
|
||||
After deciding the fate for all hunks, if there is any hunk
|
||||
that was chosen, the index is updated with the selected hunks.
|
||||
|
||||
diff::
|
||||
|
||||
This lets you review what will be committed (i.e. between
|
||||
HEAD and index).
