The replacement was done by `sed`.
This should only change versions of the docs prior to 864869ab (in
particular, not the `latest` version nor the `prerelease` version), and
make it as though the old version of the docs were compiled with that
commit. It tries to solve the same problem:
https://www.google.com/search?q=jj+revsets still points to jj v0.13
docs.
Google seems really slow to update its index, and I'm beginning to worry
that it might think we have a spammy site with many almost identical
pages. I hope it will pick up this change once it tries to update its
crawl of pages it's already indexing.

<p>Let's start by cloning GitHub's Hello-World repo using <code>jj</code>:
|
|
<div class="highlight"><pre><span></span><code><span class="c1"># Note the "git" before "clone" (there is no support for cloning native jj</span>
|
|
<span class="c1"># repos yet)</span>

|
|
$<span class="w"> </span><span class="nb">cd</span><span class="w"> </span>Hello-World
|
|
</code></pre></div></p>
|
|
<p>Running <code>jj st</code> (short for<code>jj status</code>) now yields something like this:
|
|
<div class="highlight"><pre><span></span><code>$<span class="w"> </span>jj<span class="w"> </span>st
|
|

|
|
The<span class="w"> </span>working<span class="w"> </span>copy<span class="w"> </span>is<span class="w"> </span>clean
|
|
</code></pre></div></p>
|
|
<p>We can see from the output above that our working copy is a real commit with a
|
|
commit ID (<code>d7439b06fbef</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>
|
|
<h2 id="creating-our-first-change">Creating our first change<a class="headerlink" href="#creating-our-first-change" title="Permanent link">¶</a></h2>
|
|
<p>Now let's say we want to edit the <code>README</code> file in the repo to say "Goodbye"
|
|
instead of "Hello". Let's start by describing the change (adding a
|
|
commit message) so we don't forget what we're working on:
|
|
<div class="highlight"><pre><span></span><code><span class="c1"># This will bring up $EDITOR (or `pico` or `Notepad` by default). Enter</span>
|
|
<span class="c1"># something like "Say goodbye" in the editor and then save the file and close</span>
|
|
<span class="c1"># the editor.</span>
|
|
$<span class="w"> </span>jj<span class="w"> </span>describe

|
|
</code></pre></div></p>
|
|
<p>Now make the change in the README:
|
|
<div class="highlight"><pre><span></span><code><span class="c1"># Adjust as necessary for compatibility with your flavor of `sed`</span>
|
|
$<span class="w"> </span>sed<span class="w"> </span>-i<span class="w"> </span><span class="s1">'s/Hello/Goodbye/'</span><span class="w"> </span>README

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 untrack <path></code>.</p>
|
|
<p>To see the diff, run <code>jj diff</code>:
|
|
<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>

|
|
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. For familiarity for user coming from other
|
|
VCSs, there is also a <code>jj checkout/co</code> command, which is practically a synonym
|
|
for <code>jj new</code> (you can specify a destination for <code>jj new</code> as well).</p>
|
|
<p>So, let's say we're now done with this change, so we create a new change:
|
|
<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>aef4df99ea11<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>
|
|
$<span class="w"> </span>jj<span class="w"> </span>st
|
|
Parent<span class="w"> </span>commit:<span class="w"> </span>5d39e19dac36<span class="w"> </span>Say<span class="w"> </span>goodbye
|
|
Working<span class="w"> </span>copy<span class="w"> </span>:<span class="w"> </span>aef4df99ea11<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>
|
|
The<span class="w"> </span>working<span class="w"> </span>copy<span class="w"> </span>is<span class="w"> </span>clean
|
|
</code></pre></div></p>
|
|
<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 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>, and <code>jj amend</code> is in fact an alias for
|
|
<code>jj squash</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 checkout-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 checkout</code> so you can easily review your adjustments with
|
|
<code>jj diff</code> before running <code>jj squash</code>. </p>

|
<p>The <code>@</code> indicates the working-copy commit. The first ID on a line
|
|
(e.g. "mpqrykypylvy" above) is the "change ID", which is an ID that follows the
|
|
commit as it's rewritten (similar to Gerrit's Change-Id). The second ID is the
|
|
commit ID, which changes when you rewrite the commit. 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>-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>branches()</code> refers to all commits pointed to by branches. We can combine
|
|
expressions with <code>|</code> for union, <code>&</code> for intersection and <code>~</code> for difference. For
|
|
example:

<p>The <code>000000000000</code> commit (change ID <code>zzzzzzzzzzzz</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). There are also a
|
|
few more functions, such as <code>heads(<set>)</code>, which filters out revisions in the
|
|
input set if they're ancestors of other revisions in the set.</p>

|
|
<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 <code>jj log</code> 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>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
|
|
ovknlmrokpkl</code>. That will hide the commit from the log output and will rebase any

descendants to its parent.</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>
|

<h2 id="moving-content-changes-between-commits">Moving content changes between commits<a class="headerlink" href="#moving-content-changes-between-commits" title="Permanent link">¶</a></h2>
|
|
<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. These commands assume that you have <code>meld</code> installed. If you prefer a
|
|
terminal-based diff editor, you
|
|
can <a href="../config/#setting-up-scm-diff-editor">configure <code>scm-diff-editor</code></a> instead.</p>
|
|
<p>We'll need some more complex content to test these commands, so let's create a
|
|
few more commits:

|
|
<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 -i</code> (short for <code>jj squash --interactive</code>) 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:
|
|
<div class="highlight"><pre><span></span><code>$<span class="w"> </span>jj<span class="w"> </span>squash<span class="w"> </span>-i
|
|
Using<span class="w"> </span>default<span class="w"> </span>editor<span class="w"> </span><span class="s1">'meld'</span><span class="p">;</span><span class="w"> </span>you<span class="w"> </span>can<span class="w"> </span>change<span class="w"> </span>this<span class="w"> </span>by<span class="w"> </span>setting<span class="w"> </span>ui.diff-editor

|
|
</code></pre></div>
|
|
That will bring up Meld with a diff of the changes in the "ABCD" commit. Modify
|
|
the right side of the diff to have the desired end state in "ABC" by removing
|
|
the "D" line. Then save the changes and close Meld. If we look at the diff of
|
|
the second commit, we now see that all three lines got capitalized:
|
|
<div class="highlight"><pre><span></span><code>$<span class="w"> </span>jj<span class="w"> </span>diff<span class="w"> </span>-r<span class="w"> </span>@-
|

|
|
</code></pre></div></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 contents of a commit without
|
|
checking it out.

When Meld starts, edit the right side by e.g. adding something to the first
|
|
line. Then save the changes and close Meld. You can now inspect the rewritten
|
|
commit with <code>jj diff -r @-</code> again and you should see your addition to the first
|
|
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>Other commands for rewriting contents of existing commits are <code>jj split</code>, <code>jj
|
|
unsquash -i</code> and <code>jj move -i</code>. Now that you've seen how <code>jj squash -i</code> and <code>jj
|
|
diffedit</code> work, you can hopefully figure out how those work (with the help of
|
|
the instructions in the diff).</p>
