Hands On: Creating a Useful Shell Script

I use the static site generator Jekyll to write my blog. I store the site at Github, who then translates and hosts it all for me for free. Jekyll is simple to use and I like it a lot. There’s only one problem: it’s a bit manual.

Every post that you create has to have a very specific filename in the form of year-month-day-post-slug.md. Not that big of a problem, just a mere annoyance. In addition, every post you have must have a blob of text at the top called the front matter. Again: not a huge problem, just kind of time consuming. The perfect candidate for a little help from a shell script.

#!/bin/bash
# a Jekyll post creator, which creates a new file, adds frontmatter,
# and opens the editor and starts Jekyll
new_post() {
  JEKYLL_ROOT=~/Documents/Sites/conery-io-jekyll
  JEKYLL_POSTS=$JEKYLL_ROOT/_posts
  TITLE=$1
  SLUGIFIED="$(echo -n "$TITLE" | sed -e 's/[^[:alnum:]]/-/g' | tr -s '-' | tr A-Z a-z)"
  NEW_POST_FILE=$JEKYLL_POSTS/$(date +%Y-%m-%d-$SLUGIFIED.md)

  cat <<frontmatter > $NEW_POST_FILE
---
layout: post-minimal
title: "$TITLE"
image: ''
comments: false
categories:
summary: ""
---
frontmatter

  echo "New post created, opening in Atom, starting Jekyll"
  atom $NEW_POST_FILE
  jekyll serve -s $JEKYLL_ROOT
}
  • Design Patterns: Creational

    Tried and true design patterns for creating objects in an object-oriented language.

  • Design Patterns: Structural

    As your application grows in size you need to have a plan to handle the increase in complexity. The Gang of Four have some ideas that could work for you.

  • Design Patterns: Behavioral

    Mediators, Decorators and Facades - this is the deep end of object-oriented programming and something you'll come face to face with as your application grows.

  • Principles of Software Design

    You've heard the terms before: YAGNI, SOLID, Tell Don't ASK, DRY... what are they and what do they mean?

  • Testing Your Code: TDD and BDD

    Testing code has moved beyond the realm of QA and into the realm of design, asking you to think about what you do before you do it. Let's have a look at some strategies.

  • Shell Script Basics

    It's a Unix world. You should have a functional knowledge of how to get around a Unix machine using the command line, as well as how to complete basic tasks using shell scripts and Make files.

  • Making Your Life Easier with Make

    Make is a build utility that works with a file called a Makefile and basic shell scripts. It can be used to orchestrate the output of any project that requires a build phase. It's part of Linux and it's easy to use.

  • Using Make to Improve Your Test Suite

    Make has been around forever and is often overlooked in favor of tools that recreate precisely what it does, but in crappier ways. Let's see how you can use Make to help your testing process.
