GREP_COLORS tool

Seems I’ve been all about the terminal customisation recently…

I use grep a lot. Multiple times every day without fail. I used ack for a while when I started at my current workplace as that seemed to be favoured by a lot of the existing devs there. However, I found that not having ack on some servers meant I was making silly mistakes when using grep elsewhere. Ever typed this:

grep -R 'variable'

and sat there waiting? Well I have. So I switched away from ack and became a grep advocate. This move from ack might also help explain my grep default flags, one of which (that I didn’t mention in that post..) is -P to use perlre in the search string.

github.io pages

I’ve been sharing my code via github a lot more lately. I’ve used Google Code in the past and haven’t really used github extensively. Using it more and more now has made me feel I should share my tools via github.io, not a lot of people want to go to links on someone elses blog in case they’re using it to gain money via ads or something. I don’t use advertising, I can’t stand ads in general and block them in any way I can, so you don’t need to worry about that here!

Anyway, I’ve added my recent tools and script to a github.io page which is accessible here:

https://dom111.github.io/

I’ll continue to publish articles here as well, and would like to use this as a way to get feedback and elaborate on any interesting parts of the code I’ve written. As well as write more rambles if and when I feel the need!

terminal-preview

terminal-preview is a collection of JavaScript and CSS that will enable parsing and styling of terminal ANSI escape codes for simple preview. It’s been developed as a result of my experimenting with bash-ps1 and image-to-ansi.

I’d wanted to extract the code I used in the those projects into a stand-alone project/component that could be added to an existing page where ANSI escape sequences need to be interpreted. I’ve toyed with the idea of making it a Web Component or something like that but haven’t just yet.

Learning Perl through code golf

Before I started with my current employer almost six years ago I moved from a small, privately-owned, web development company with a few developers working in the languages we chose (or at least, could make a good enough argument for) and with tools recommended by each other or the latest and greatest libraries we’d recently discovered. This was great fun and whilst we dabbled in other languages, learning Ruby and Python, tinkering with shell scripts and Haskell, there were things we didn’t touch because we didn’t have to. That was, until another developer that was no longer with us, created a Perl script that needed updating. The fear in our eyes when that script came up, or when it needed to be used again for another client…
