In Git you can add a submodule to a repository. This is basically a repository embedded in your main repository. This can be very useful. A couple of usecases of submodules:
- Separate big codebases into multiple repositories.
module Where | |
class <<self | |
attr_accessor :editor | |
def is_proc(proc) | |
source_location(proc) | |
end | |
def is_method(klass, method_name) | |
source_location(klass.method(method_name)) |

WEBrick is a Ruby library that makes it easy to build an HTTP server with Ruby. | |
It comes with most installations of Ruby by default (it’s part of the standard library), | |
so you can usually create a basic web/HTTP server with only several lines of code. | |
The following code creates a generic WEBrick server on the local machine on port 1234, |
I think the most confusing thing that I have found about Ruby on Rails so far has been the transition from (trying to) write code myself to the use of the fabled "Rails Magic". So, to help my own understanding of a few core Ruby on Rails concepts, I have decided to write something on what I think is a CRITICAL topic... the idea of Convention over Configuration and why (in my mind) it is the most important thing that helps Rails become magic!
(This may be a topic that we cover in more detail in class but as I said, I'm writing this for my own understanding... I hope it helps someone else understand things too... Perhaps you can give me a hand when I'm crying next week!)
##Convention over configuration ###What does this "actually" mean...
When you modify a file in your repository, the change is initially unstaged. In order to commit it, you must stage it—that is, add it to the index—using git add
. When you make a commit, the changes that are committed are those that have been added to the index.
git reset
changes, at minimum, where your current branch is pointing. The difference between --mixed
and --soft
is whether or not your index is also modified. So, if we're on branch master
with this series of commits:
- A - B - C (master)
HEAD
points to C
and the index matches C
.
That is is basically a "fork" of blog article i'm constantly returning to. It seems that the blog is down:
Dave Bass proposed this which I picked up for my implementation (here for an 8-chars token):
