|
|
<p>Let's look at that output as it introduces new concepts. You can see two
|
|
commits: Parent and working copy. Both are identified using two separate
|
|
identifiers: the "change ID" and the "commit ID".</p>
|
|
<p>The parent commit, for example, has the change ID <code>orrkosyo</code> and the commit ID
|
|
<code>7fd1a60b</code>.</p>
|
|
<blockquote>
|
|
<p><strong>Git users:</strong> The commit ID/hash is what you're used to from Git and should
|
|
match what you see when you look at the repository using <code>git log</code> in a Git
|
|
checkout of the repository.
|
|
The change ID however, is a new concept, unique to Jujutsu.</p>
|
|
</blockquote>
|
|
<p>We can also see from the output above that our working copy is an actual commit
|
|
with a commit ID (<code>d7439b06</code> in the example). When you make a change in the
|
|
working copy, the working-copy commit gets automatically amended by the next
|
|
<code>jj</code> command.</p>
|
|
<blockquote>
|
|
<p><strong>Git users:</strong> This is a huge difference from Git where the working copy is a
|
|
separate concept and not yet a commit.</p>
|
|
</blockquote>
|
|
<h2 id="changes">Changes<a class="headerlink" href="#changes" title="Permanent link">¶</a></h2>
|
|
<p>A change is a commit that can evolve while keeping a stable identifier (similar
|
|
to Gerrit's Change-Id). In other words: You can make changes to files in a
|
|
change, resulting in a new commit hash, but the change ID will remain the same.</p>
|
|
<p>You can see that our clone operation automatically created a new change:</p>
|
|
<div class="highlight"><pre><span></span><code>Working<span class="w"> </span>copy<span class="w"> </span>:<span class="w"> </span>kntqzsqt<span class="w"> </span>d7439b06<span class="w"> </span><span class="o">(</span>empty<span class="o">)</span><span class="w"> </span><span class="o">(</span>no<span class="w"> </span>description<span class="w"> </span><span class="nb">set</span><span class="o">)</span>
|
|
</code></pre></div>
|
|
<p>This new change has the ID <code>kntqzsqt</code> and it is currently empty (contains no
|
|
changes compared to the parent) and has no description.</p>

|
<h2 id="creating-our-first-change">Creating our first change<a class="headerlink" href="#creating-our-first-change" title="Permanent link">¶</a></h2>
|
|
<p>Let's say we want to edit the <code>README</code> file in the repo to say "Goodbye"
|
|
instead of "Hello". Start by describing the change (adding a commit message) so
|
|
we don't forget what we're working on:</p>
|
|
<div class="highlight"><pre><span></span><code><span class="c1"># This brings up $EDITOR (or `pico` or `Notepad` by default).</span>
|
|
<span class="c1"># Enter something like "Say goodbye" in the editor and then save the file and close</span>

|
|
</code></pre></div>
|
|
<p>Note that you didn't have to tell Jujutsu to add the change like you would with
|
|
<code>git add</code>. You actually don't even need to tell it when you add new files or
|
|
remove existing files. To untrack a path, add it to your <code>.gitignore</code> and run
|
|
<code>jj file untrack <path></code>.</p>
|
|
<p>Also note that the commit hash for our current change (<code>kntqzsqt</code>) changed from
|
|
<code>e427edcf</code> to <code>5d39e19d</code>!</p>
|
|
<p>To see the diff, run <code>jj diff</code>:</p>
|
|
<div class="highlight"><pre><span></span><code>$<span class="w"> </span>jj<span class="w"> </span>diff<span class="w"> </span>--git<span class="w"> </span><span class="c1"># Feel free to skip the `--git` flag</span>

</code></pre></div>
|
|
<p>Jujutsu's diff format currently defaults to inline coloring of the diff (like
|
|
<code>git diff --color-words</code>), so we used <code>--git</code> above to make the diff readable in
|
|
this tutorial.</p>
|
|
<p>As you may have noticed, the working-copy commit's ID changed both when we
|
|
edited the description and when we edited the README. However, the parent commit
|
|
stayed the same. Each change to the working-copy commit amends the previous
|
|
version. So how do we tell Jujutsu that we are done amending the current change
|
|
and want to start working on a new one? That is what <code>jj new</code> is for. That will
|
|
create a new commit on top of your current working-copy commit. The new commit
|
|
is for the working-copy changes.</p>
|
|
<p>So, let's say we're now done with this change, so we create a new change:</p>
|
|
<div class="highlight"><pre><span></span><code>$<span class="w"> </span>jj<span class="w"> </span>new
|
|
Working<span class="w"> </span>copy<span class="w"> </span>now<span class="w"> </span>at:<span class="w"> </span>mpqrykyp<span class="w"> </span>aef4df99<span class="w"> </span><span class="o">(</span>empty<span class="o">)</span><span class="w"> </span><span class="o">(</span>no<span class="w"> </span>description<span class="w"> </span><span class="nb">set</span><span class="o">)</span>

|
|
</code></pre></div>
|
|
<p>If we later realize that we want to make further changes, we can make them in
|
|
the working copy and then run <code>jj squash</code>. That command squashes (moves) the
|
|
changes from a given commit into its parent commit. Like most commands, it acts
|
|
on the working-copy commit by default. When run on the working-copy commit, it
|
|
behaves very similar to <code>git commit --amend</code>.</p>
|
|
<p>Alternatively, we can use <code>jj edit <commit></code> to resume editing a commit in the
|
|
working copy. Any further changes in the working copy will then amend the
|
|
commit. Whether you choose to create a new change and squash, or to edit,
|
|
typically depends on how done you are with the change; if the change is almost
|
|
done, it makes sense to use <code>jj new</code> so you can easily review your adjustments
|
|
with <code>jj diff</code> before running <code>jj squash</code>.</p>
|
|
<p>To view how a change has evolved over time, we can use <code>jj evolog</code> to see each
|
|
recorded change for the current commit. This records changes to the working
|
|
copy, message, squashes, rebases, etc.</p>

in its <code>jj log</code> command:</p>

<p>The <code>@</code> indicates the working-copy commit. The first ID on a line
|
|
(e.g. "mpqrykyp" above) is the change ID. The second ID is the commit ID. You
|
|
can give either ID to commands that take revisions as arguments. We will
|
|
generally prefer change IDs because they stay the same when the commit is
|
|
rewritten.</p>
|
|
<p>By default, <code>jj log</code> lists your local commits, with some remote commits added
|
|
for context. The <code>~</code> indicates that the commit has parents that are not included
|
|
in the graph. We can use the <code>--revisions</code>/<code>-r</code> flag to select a different set
|
|
of revisions to list. The flag accepts a <a href="../revsets/">"revset"</a>, which is an
|
|
expression in a simple language for specifying revisions. For example, <code>@</code>
|
|
refers to the working-copy commit, <code>root()</code> refers to the root commit,
|
|
<code>bookmarks()</code> refers to all commits pointed to by bookmarks (similar to Git's
|
|
branches). We can combine expressions with <code>|</code> for union, <code>&</code> for intersection
|
|
and <code>~</code> for difference. For example:</p>
|
|
<div class="highlight"><pre><span></span><code>$<span class="w"> </span>jj<span class="w"> </span>log<span class="w"> </span>-r<span class="w"> </span><span class="s1">'@ | root() | bookmarks()'</span>

|
|
<p>The <code>00000000</code> commit (change ID <code>zzzzzzzz</code>) is a virtual commit that's called
|
|
the "root commit". It's the root commit of every repo. The <code>root()</code>
|
|
function in the revset matches it.</p>
|
|
<p>There are also operators for getting the parents (<code>foo-</code>), children (<code>foo+</code>),
|
|
ancestors (<code>::foo</code>), descendants (<code>foo::</code>), DAG range (<code>foo::bar</code>, like
|
|
<code>git log --ancestry-path</code>), range (<code>foo..bar</code>, same as Git's). See
|
|
<a href="../revsets/">the revset documentation</a> for all revset operators and functions.</p>
|
|
<blockquote>
|
|
<p><strong>Hint:</strong> If the default <code>jj log</code> omits some commits you expect to see, you
|
|
can always run <code>jj log -r ::</code> (or, equivalently, <code>jj log -r 'all()'</code>) to see
|
|
all the commits.</p>

|
|
<p>Now let's see how Jujutsu deals with merge conflicts. We'll start by making some
|
|
commits. We use <code>jj new</code> with the <code>--message</code>/<code>-m</code> option to set change
|

|
|
<p>There are several things worth noting here. First, the <code>jj rebase</code> command said
|
|
"Rebased 2 commits". That's because we asked it to rebase commit B2 with the
|
|
<code>-s</code> option, which also rebases descendants (commit C in this case). Second,
|
|
because B2 modified the same file (and word) as B1, rebasing it resulted in
|
|
conflicts, as the output indicates. Third, the conflicts did not prevent the
|
|
rebase from completing successfully, nor did it prevent C from getting rebased
|
|
on top.</p>
|
|
<p>Now let's resolve the conflict in B2. We'll do that by creating a new commit on
|
|
top of B2. Once we've resolved the conflict, we'll squash the conflict
|
|
resolution into the conflicted B2. That might look like this:</p>

<p>Note that commit C automatically got rebased on top of the resolved B2, and that
|
|
C is also resolved (since it modified only a different file).</p>
|
|
<p>By the way, if we want to get rid of B1 now, we can run <code>jj abandon
|
|
ovknlmro</code>. That will hide the commit from the log output and will rebase any
|
|
descendants to its parent.</p>

the "operation log". Use the <code>jj op</code> (short for <code>jj operation</code>) family of

<p>As you can perhaps see, that undid the <code>jj squash</code> invocation we used for
|
|
squashing the conflict resolution into commit B2 earlier. Notice that it also
|
|
updated the working copy.</p>
|
|
<p>You can also view the repo the way it looked after some earlier operation. For
|
|
example, if you want to see <code>jj log</code> output right after the <code>jj rebase</code>
|
|
operation, try <code>jj log --at-op=367400773f87</code> but use the hash from your own
|
|
<code>jj op log</code>.</p>

|
|
<p>You have already seen how <code>jj squash</code> can combine the changes from two commits
|
|
into one. There are several other commands for changing the contents of existing
|
|
commits.</p>
|
|
<p>We'll need some more complex content to test these commands, so let's create a
|
|
few more commits:</p>

<p>We "forgot" to capitalize "c" in the second commit when we capitalized the other
|
|
letters. We then fixed that in the third commit when we also added "D". It would
|
|
be cleaner to move the capitalization of "c" into the second commit. We can do
|
|
that by running <code>jj squash</code> with the <code>--interactive</code>/<code>-i</code> option on the third
|
|
commit. Remember that <code>jj squash</code> moves all the changes from one commit into its
|
|
parent. <code>jj squash -i</code> moves only part of the changes into its parent. Now try
|
|
that:</p>

<p>That will bring up the built-in diff editor<sup id="fnref:alternative_diff_editors"><a class="footnote-ref" href="#fn:alternative_diff_editors">1</a></sup> with a
|
|
diff of the changes in the "ABCD" commit. Expand the file by clicking on <code>(+)</code>
|
|
or with right arrow, then select the sections/line to include by clicking or
|
|
using space. Once complete, press <code>c</code> to confirm changes, or <code>q</code> to exit without

saving. You can also use the mouse to click on the menu items to see more

options (keyboard navigation is currently limited).</p>

<p>The child change ("ABCD" in our case) will have the same content <em>state</em> after
|
|
the <code>jj squash</code> command. That means that you can move any changes you want into
|
|
the parent change, even if they touch the same word, and it won't cause any
|
|
conflicts.</p>
|
|
<p>Let's try one final command for changing the contents of an exiting commit. That
|
|
command is <code>jj diffedit</code>, which lets you edit the changes in a commit without
|
|
checking it out.</p>

<p>In the diff editor, use the arrow keys and spacebar to select all lines but the
|
|
last. Press 'c' to save the changes and close it. You can now inspect the
|
|
rewritten commit with <code>jj diff -r @-</code> again, and you should see your deletion of
|
|
the last line. Unlike <code>jj squash -i</code>, which left the content state of the commit
|
|
unchanged, <code>jj diffedit</code> (typically) results in a different state, which means
|
|
that descendant commits may have conflicts.</p>
|
|
<p>Another command for rewriting contents of existing commits is <code>jj split</code>. Now
|
|
that you've seen how <code>jj squash -i</code> and <code>jj diffedit</code> work, you can hopefully
|
|
figure out how it works (with the help of the instructions in the diff).</p>

<p>There are many other diff editors you could use.

For example, if you have <a href="https://meldmerge.org">Meld</a> installed and in the

PATH, you can use it via <code>jj squash -i --tool meld</code> or a fancier config with <code>jj
|
|
squash -i --tool meld-3</code>. You can configure the default with the
|
|
<a href="../config/#editing-diffs"><code>ui.diff-editor</code> option</a>; those docs also explain how

to specify a path to an executable if it is not in the PATH. <a class="footnote-backref" href="#fnref:alternative_diff_editors" title="Jump back to footnote 1 in the text">↩</a></p>
