Subject: [PATCH] doc: add some nit fixes to MyFirstContribution
Date: Wed, 29 May 2019 13:18:09 -0700	[thread overview]
Message-ID: <20190529201809.169065-1-emilyshaffer@google.com> (raw)
In-Reply-To: <20190517190359.21676-1-emilyshaffer@google.com>

A trial run-through of the tutorial revealed a few typos and missing
commands in the tutorial itself. This commit fixes typos, clarifies
which lines to keep or modify in some places, and adds a section on
putting the git-psuh binary into the gitignore.

This patch is based on next, as the doc hasn't made it to master yet.

- Missing `cd git` after cloning the repo
- Documented how to add git-psuh to the gitignore
- Documented the need to leave prior printfs in place during the
  tutorial
- Typos: missing ;, stray newline
- Missing `git add builtin/psuh.c` in a couple of places; this could
  also have been done by adding the filename to the end of the commit
  call, but I don't think that's a good habit (as opposed to staging all
  changes, inspecting the wt state, and then committing). Open for
  debate.

Big thanks to Christian for the trial run and review.

 - Emily

 Check it out! You've got a command! Nice work! Let's commit this.
 
+`git status` reveals modified `Makefile`, `builtin.h`, and `git.c` as well as
+untracked `builtin/psuh.c` and `git-psuh`. First, let's take care of the binary,
+which should be ignored. Open `.gitignore` in your editor, find `/git-push`, and
+add an entry for your new command in alphabetical order:

+----
+...
+/git-prune-packed
+/git-psuh
+/git-pull
+/git-push
+/git-quiltimport
+/git-range-diff
+...
+----
+
+Checking `git status` again should show that `git-psuh` has been removed from
+the untracked list and `.gitignore` has been added to the modified list. Now we
+can stage and commit:
