Examining a changeset in HG

Question

How can I examine a changeset in mercurial without looking up its parent? In mercurial, what's the equivalent of ``` git show HEAD^ ``` Git-show gives the changeset metadata and the diff as well.

Accepted Answer

Your question has two parts. First, how to get the metadata and diff for a changeset all at once:

```
hg log --patch --rev tip
```

You can shorten the options:

```
hg log -pr tip
```

The second part of the question is how to say "the parent changeset of X" without looking it up. For that you can use the parentrevspec extension Martin mentioned.

Once you enable the extension you can do:

```
hg log -pr tip^
```

You could add an alias to your `~/.hgrc` file if you don't want to retrain your fingers from git's command:

```
[alias]
show = log -pr
```

Then you could use:

```
hg show tip^
```
