CodeSnap Web Application


This project almost did not come into existence. There are lots of tools out there for collecting and cataloging code snippets, and I looked at several of them as alternatives to making my own. Given the amount of time and effort it would take to make my own code snippet library generator, I was more inclined to make something that was already available work for me and my students.

However, nothing did exactly what I wanted, so after a few fits and starts, CodeSnap was born.


The Challenge

When I teach web design and development classes, I often need to get code snippets to students so we can speed past the basic parts and get to the heart of the lesson.

Most of the code snippet tools available are for developers to manage and keep track of their own code snippets. It seemed reasonable that I could make one of those systems work for me, but I just found the experience unsatisfactory.

What I really wanted was a way of creating an individual file to go with an individual project that had snippets students could copy and paste from.

It was fairly important to me that this file be entirely self contained, so that I could give it out with other project files, or send it by email, and the students could just open it in the browser and use it without any fuss.


First, I should let you know this web application is currently incomplete. However, it works well for my purposes and I have been successfully using it since 2014 with students. If you want to give it a try, you can download it and install it from GitHub. It runs great on localhost, or you can put it on your own web server.

Probably the best way to get started in understanding this project is to see the final result.

Essentially, I enter code snippets into a form, and then when I have all the snippets I want to include, the application generates a file that I can download and give to my students.


The image above shows what a finished file might look like, or you can see a live example.

The foundation for this project is this excellent sitepoint article about best practices for code snippets.

I manually built a snippet or two using his files as a template and quickly realized that building snippets manually would take forever.

However, building a little PHP application would not be so difficult.

Syntax highlighting was another challenge. I didn’t want to have to manually highlight different bits of the code, and so the Google code-prittify library came to the rescue.

The documentation for the library is terrible, but after some experimentation, I got it to work the way I wanted it to.

The web application allows you to create a title, add tags and an intro to the snippet if you want to provide some explanation. The caption goes at the top of the snippet container, then comes the snippet itself.

The default syntax highlighting works well more most the languages I use (HTML, PHP, JavaScript), however, CSS is a bit different, so I added a option that you must select to make CSS work properly.

You can then add another code snippet, or generate the file if you are done. When you generate the file, the data in the various fields goes into a database, and PHP actually makes a file and saves it into the repository folder.

The nice thing about these files is that they are entirely self contained. Each file includes all the HTML/CSS and JavaScript necessary to render the snippets properly, so if you want you can attach the file to an email and send it to someone, or deliver it in any number of ways and it will just work.
