Making your code pip installable

aka when to use a CutomBuildCommand or a CustomInstallCommand when building python packages with setup.py

Bioinformatics software is complicated, and often a little bit messy. Recently I found myself wading through a python package building quagmire and thought I could share something I learnt about when to use a custom build command and when to use a custom install command. I have also provided some information about how to copy executables to your package installation bin. **ChatGPT wrote the initial skeleton draft of this post, and I have corrected and edited.

Next time you need to create a pip installable package yourself, hopefully this can save you some time!

Unreasonably faster notes, with command-line fuzzy search

A good note system should act like a second brain:

  1. Accessible in seconds
  2. Adding information should be frictionless
  3. Searching should be exhaustive – if it’s there, you must find it

The benefits of such a note system are immense – never forget anything again! Search, perform the magic ritual of Copy Paste, and rejoice in the wisdom of your tried and tested past.

But how? Through the unreasonable effectiveness of interactive fuzzy search. This is how I have used Fuz, a terminal-based file fuzzy finder, for about 4 years.

Briefly, Fuz extracts all text within a directory using ripgrep, enables interactive fuzzy search with FZF, and returns you the selected item. As you type, the search results get narrowed down to a few matches. Files are opened at the exact line you found. And it’s FAST – 100,000 lines in half a second fast.

Using Fuz to quickly add a code-snippet in our note directory – then retrieving it with fuzzy-search. Here, on how to read FASTA files with Biopython, conveniently added to a file called biopython.py.

How to Install Open Source PyMOL on Windows 10

It is possible to get an installer for the crystallographer’s favourite molecular visualization tool for Windows machines, that is if you are willing to pay a fee. Fortunately, Christoph Gohlke has made available free, pre-compiled Windows versions of the latest PyMOL software, along with all of it’s requirements, it’s just not particularly straightforward to install. The PyMOLWiki offers a three-step guide on how to do this and I will break it down to make it somewhat clearer.

1. Install the latest version of Python 3 for Windows

Download the Windows Installer (x-bit) for Python 3 from their website, x being your Windows architecture – 32 or 64.

Then, follow the instructions on how to install it. You can check if it has installed by running the following in PowerShell:
