Here's a quick trick using the Python library pygments to enable pretty colors in your terminal when viewing source code. It detects which syntax highlighter to use by the file's extension.

I'm a terminal command line basher (see what I did there?). While I understand the appeal of IDEs, I created from the command line. I use Sublime as a lightweight text editor, but for everything else, I like to tickle the keys. I started using computers before the GUI era, and it has stuck with me. It might also have something to do with the fact I took piano lessons for many years!
One trick I waited far too long to implement was to get a good syntax highlighter at my command line. It is relatively straight forward. First, I install the Python package pygments system-wide with pip.
sudo pip install pygments
Next, I create an alias in my home directories .bashrc file. I'll add line numbers for good measure.
alias ccat='pygmentize -O style=monokai,linenos=1 -f terminal -g'
After doing this, I now have a colored cat command, or ccat. It can be used as follow, with pretty results.
$ ccat settings.py 0001: from django.conf import settings 0002: 0003: from .models import Settings 0004: 0005: 0006: def get_setting(key, default): 0007: """ 0008: Returns a value for key from the Settings model. 0009: """ 0010: setting = Settings.objects.get(key=key) 0011: 0012: 0013: def get_clear_cache(): 0014: """ 0015: Default to clearing the cache after each page edit. 0016: """ 0017: 0018: return getattr(settings, "WP_CLEAR_CACHE", False)
Small things like this help make me a better developer. It makes source code in the terminal very clear, and pygments supports a vast array of languages for highlighting.
