Creating And Updating Changeset

===============================

Setup the Base Repo

-------------------

We start with a plain base repo::

  $ hg init main; cd main

  $ cat >main-file-1 <<-EOF

  > One

  > 

  > Two

  > 

  > Three

  > EOF

  $ echo Two >main-file-2

  $ hg add

  adding main-file-1

  adding main-file-2

  $ hg commit --message base

  $ cd ..

and clone this into a new repo where we do our work::

  $ hg clone main work

  updating to branch default

  2 files updated, 0 files merged, 0 files removed, 0 files unresolved

  $ cd work

Create First Patch

------------------

To begin with, we just do the changes that will be the initial version of the changeset::

  $ echo One >file-from-A

  $ sed -i'' -e s/One/Eins/ main-file-1

  $ hg add file-from-A

So this is what we would like our changeset to be::

  $ hg diff

  diff --git a/file-from-A b/file-from-A

  new file mode 100644

  --- /dev/null

  +++ b/file-from-A

  @@ -0,0 +1,1 @@

  +One

  diff --git a/main-file-1 b/main-file-1

  --- a/main-file-1

  +++ b/main-file-1

  @@ -1,1 +1,1 @@

  -One

  +Eins

To commit it we just - commit it::

  $ hg commit --message "a nifty feature"

and place a bookmark so we can easily refer to it again (which we could have done before the commit)::

  $ hg book feature-A

Create Second Patch

-------------------

Let's do this again for the second changeset::

  $ echo Two >file-from-B

  $ sed -i'' -e s/Two/Zwie/ main-file-1

  $ hg add file-from-B

Before committing, however, we need to switch to a new bookmark for the second

changeset. Otherwise we would inadvertently move the bookmark for our first changeset.

It is therefore advisable to always set the bookmark before committing::

  $ hg book feature-B

  $ hg commit --message "another feature (child of $(hg log -r . -T '{node|short}'))"

So here we are::

  $ hg book

     feature-A                 1:568a468b60fc

   * feature-B                 2:73296a82292a

Fix The Second Patch

--------------------

There's a typo in feature-B. We spelled *Zwie* instead of *Zwei*::

  $ hg diff --change tip | grep -F Zwie

  +Zwie

Fixing this is very easy. Just change::

  $ sed -i'' -e s/Zwie/Zwei/ main-file-1

and **amend**::

  $ hg amend

This results in a new single changeset for our amended changeset, and the old

changeset plus the updating changeset are hidden from view by default::

  $ hg log
