The code for the Akka Hacking session is maintained in a git repository. The idea is to push the exercises from a private to a public repository used by the attendees.

While writing the code (and README file), mistakes are made, necessitating corrections to the different commits in the repo. Doing this 'manually' is a tedious and error-prone process. This is where git filter-branch comes into play...

See below the way in which the different source files were corrected. It started with a rename of three variables, which turned out to introduce a name clash. This in turn was corrected with further edits.

Of course, don't do this on your working copy of the repo. Instead:

- Clone the repo and remove the *remote(s)*

Note that in the this gist assumes that the following git aliases are in place:

        show-graph = log --graph --abbrev-commit --pretty=oneline
        co = checkout
        br = branch
        cm = commit
        st = status
        rb = rebase
        cp = cherry-pick

AsciiDoctor Base installation

Use gem to install asciidoctor. Follow the instructions in the documentation section of the asciidoc website.

Note: I had to quit the current terminal session and start a new one after which the asciidoctor command became available.

Converting markdown sources to asciidoc

This can be done using kramdown. I followed the instructions on one of Matthew Setter blog articles.
