cli tools are super handy and easy to add to your python libraries to supercharge them. Even if your library is not a cli tool there are a number of things that a cli can do to your library. Example Ideas # Things a cli can do to enhance your library. 🆚 print version 🕶 print readme 📝 print changelog 📃 print config ✏ change config 👩‍🎓 run a tutorial 🏗 scaffold a project with cookiecutter 🖱 Click # Click is the most popular python cli tool framework for python. There are others, some old, some new comers that make take the crown. For now Click is the gold standard if you want to make a powerful cli quickly. If you are dependency conscious and dont need a lot of tooling, use argparse. Project Structure # ❯ cli.py # ✨ init.py # For our simple_click library can be left empty. It is here purely to signify that simple_click is a library. It is likely that you will import other modules here that need to reside at the top level of your library api, your cli does not need to be at the top of of…

I love using URL shorteners to easily share links without hitting character limits, but they loose their meaning. Services like bit.ly will save my links for me so that I can find them, but I would rather them to be easy to remember. https://bit.ly/2ruLwQz does not roll of the tongue so well. 301 🤸‍♀️ # I recently discovered a really cool feature of netlify that I have always looked past,. It is so simple cool and powerful, every netlify site should do this! But how 🤷‍♀️ # simply add a file to the root of your your published site with the following format. The trick I found with my gatsby site was that it needed to be in my static directory, not root. Next you just put space separated links on separate lines. #’s can be used for comments. 🙌 Share those short links # Now with shorter links we have more space for our content without needing to use a service like bit.ly that makes our links unreadable.

I spend a lot of my time at the terminal for my daily work, mostly in Linux or wsl. One big reason for using wsl over cmd.exe is the ease of walking through history that fzf provides. This week we had a windows bug in a cli and I was stuck in vanilla cmd.exe 😭 > Cmder # First off if you are stuck using cmd.exe, do yourself a favor and get cmder. It makes life just a bit easier. It is super confugurable and comes with several power ups that make it a bit more enjoyable than cmd.exe. History # F7 - Scroll through history F8 - Search history based Example #.bat # The next simple technique is to save your commands into a.bat file. Any valid command ran with cmd.exe can be saved into a bat file and called again later by running it in the terminal. save your command use f7/f8 to get your command back add at the end, hit the home key and add echo to the front. Do not wrap with quotes. This is not bash. » append type not cat # To ensure that you got the command right… and didn’t forget that yo…

Mine is the python debugger. I was a long holdout thinking that print statements were sufficient. That was untill I started having errors crop up in functions that took minutes to run. The thing that I most notably wish I would have known about is post_mortem. Example # Debug with iPython/Jupyter Vanilla Debug # More # For more information about the debugger checkout the real python article. https://realpython.com/python-debugging-pdb/ Also keep a bookmark of the table of pdb commands from the article https://realpython.com/python-debugging-pdb/#essential-pdb-commands Debug Session

I have been using oh-my-zsh successfully for about 2 years now. But lately my startup time has been really bothersome. It has grown to the point where it was taking about 5.5s to startup a shell! This is ok if I am going to spend some time in here for awhile and do some work that benefits from all of the autocompletions, plugins, and shortcuts that oh-my-zsh brings. But to only jump in to run a handful of commands is infuriating. 📑 My Setup # I believe the real issue is io speed on wsl. I have some remote servers with similar configs that are 10x faster or more, loading in 100s of milliseconds rather than seconds. Sourcing all of the individual plugin files are just too much for it. 💨 How Fast can it be # Quick side note: your zsh config is controled by your ~/.zshrc file. This file can source other files, load plugins, or run literally anything. Time the initial time Move your ~/.zshrc config file. Time the fastest startup possible with nothing in your ~/.zshrc config file. Move your…

Vim’s (neovim in my case) location list can provide some very useful information while developing. Mine gives me information about linting and type checking errors with fairly little config. Generally, it sits nicely at the bottom of the screen and barely affects me. Other times, especially while zoomed way in during a presentation, it just gets in the way. Location List eating up the screen while I am zoomed in and trying to live code Toggling the location list # Through some google search I found the culprit was syntastic. It has an feature. We can turn it off by setting. Keybindings # I want to keep the location list open automatically most of the time, but when I don’t want it to keep opening it’s generally detrimental. Trying to live code while the location list keeps taking up the whole screen is not cool. First, create a function that will toggle both the location list and syntactic together. This binding will allow me to use from normal mode to toggle the location list. I am st…
