Faster site generation with a native Octopress 2

Apr 17, 2016 - 2 minute read - Comments - metaoctopress-2octopressnative-octopressrakefilereinventing-the-wheel

Note: this article is an answer to a previous one, about the same topic: a tool for a faster site generation while developing / writing articles, using octopress 2.


Octopress 2 packs, out of the box, some tasks to speed up the site generation while you’re writing articles:

Isolate a post:

# usage rake isolate[my-post]
desc "Move all other posts than the one currently being worked on to a temporary stash location (stash) so regenerating the site happens much more quickly."
task :isolate, :filename do |t, args|
  stash_dir = "#{source_dir}/#{stash_dir}"
  FileUtils.mkdir(stash_dir) unless File.exist?(stash_dir)
  Dir.glob("#{source_dir}/#{posts_dir}/*.*") do |post|
    system "git update-index --assume-unchanged #{post}" unless post.include?(args.filename) post, stash_dir unless post.include?(args.filename)

Integrate with the rest of the posts:

desc "Move all stashed posts back into the posts directory, ready for site generation."
task :integrate do
  posts_dir = "#{source_dir}/#{posts_dir}/"
  Dir.glob("#{source_dir}/#{stash_dir}/*.*") do |post| post, posts_dir
    full_path = "#{posts_dir}/#{post.split("/").reverse.first}"
    system "git update-index --no-assume-unchanged #{full_path}"


(at the folder where the Rakefile is located)

  • isolate the selected file. Specify the pattern to keep.
rake isolate["draft"]
  • write the new content
  • commit to git
  • integrate with the rest of the files
rake integrate
  • git push


When I needed this tool, to speed up my feedback cycle, I didn’t find any that did this job, so I created a small tool for this same purpose. Unfortunately, there was one, so close to my nose that I could not find it. I was reinventing the wheel.

It is better to switch to a tool that has been tested by more users, that has received the community’s approval than a custom-made tool.

BEM 101

I’ve read this introduction to a CSS style called Block, Element, Modifier methodology (BEM).

In it,

  • a block is a top-level abstraction of a new component
  • Child items, or elements, can be placed inside and these are denoted by two underscores following the name of the block […]. modifiers can manipulate the block so that we can theme or style that particular component without inflicting changes on a completely unrelated module. This is done by appending two hyphens to the name of the block […].

Kata formulation: Find the comments

Mar 1, 2016 - 2 minute read - Comments - kataformulationphpcommentexercise

Little Johnny is inspecting a PHP source code that contains comments. These comments contains words that he doesn’t understand, as it written in another language.

Rules and constraints

The source code in the PHP files does not need to be correct.

A comment (a subset of PHP comments) is defined as:

  • A line containing C-style comment delimiter, except when it is within a string
    • // hello C-style is a valid comment
    • echo "//"; is not a comment
    • echo '//'; is not a comment
  • A line containing Perl-style comment delimiter, except when it is within a string
    • # hello Perl-style is a valid comment
    • echo "#"; is not a comment
    • echo '#'; is not a comment
  • There are no multi-line comments
    • /* ... */ is not a comment

You can do this kata in any language you want. In any case it is not allowed to use a PHP parser. This task must be done manually.

How to start

  • Clone/fork (any stars are welcome) this repo
  • Run the tests. See this for help
  • They should be red.
  • Go to production code and fix it
  • Have fun (happy kata and happy koding!)


Please do not read ahead, just read the current assignment, do it, then read the next one:

  1. Can you help Little Johnny fetch all those comments?
  2. These messages have not been audited yet and we want to publish the code, so it is better to remove the comments. Can you do it?

Optional requirement

As an optional task, when the problem is finished (you can attack in your preferred order), there must be an executable jar with some parameters to process the current folder with the ‘working modes’ specified above.

(This formulation is also present at the repository )
