Some people still use paper calendars. Stuff where you have a picture of the month and all days in the month listed. I have some relatives that do use those. On loosely related topic, I like to travel and I like to take some pictures in foreign lands. So combining both is an obvious idea – to create a calendar where pictures of the month are taken by me. I searched for some ready to use solution but haven’t found anything. So I decided to create my own simple tool. And this post is about creating that tool.
I know time and date stuff is complicated and I wasn’t really looking into learning all the rules regarding date and time and programing them. There had to be a simple way how I can use some of the tools that are already implemented. Obvious option would be to use some of the date manipulation libraries like mktime and write the tool in C. But that that sounded quite heavy weight for such a simple tool. Using Ruby would be an option, but still kinda too much and I’m not fluent rubyist and my python and perl are even rustier. I was also thinking what output format should I use to print it easily. As I was targeting some pretty printed paper LaTeX sounded like a good choice and in theory it could be used to implement the whole thing. I even found somebody who did that, but I didn’t managed to comprehend how it worked, how to modify it or even how to compile it. Turns out my LaTeX is rusty as well.
So I decided to use shell and powerful
date command to generate the content. Started with generating LaTeX code as I still want it on paper in the end, right? Trouble is, LaTeX make great papers if you want to look serious and make some serious typography. For calendar on the wall, you probably want to make it fancy and screw typography. I was trying to make it what I wanted, but it was hard. So hard I gave up. And I ended up with the winning combo – shell and html. Html is easy to view and print and CSS supports various of options including different style for screen and print type media.
Html and css made the whole exercise really easy and I have something working now on GitHub in 150 lines of code where half of it is CSS. It’s not perfect, there is plenty of space for optimization, but it is really simple and fast enough. Are you interested? Give it a try and if it doesn’t work well for you, pull requests are welcome 😉
