Vim (source code),short for Vi IMproved, is a configurable text editor often used asa Python development environment. Vim proponents commonly cite the numerousplugins, Vimscript and logical command language as major Vim strengths.

Why is Vim a good Python development environment?

Vim's philosophy is that developers are more productive when they avoidtaking their hands off the keyboard. Code should flow naturally from thedeveloper's thoughts through the keyboard and onto the screen. Using a mouseor other peripheral is a detriment to the rate at which a developer'sthoughts become code. This 'efficiency by keyboard'keeps Vim as one of the most popular text editorsdespite having been around for decades. Few programming tools have that kindof staying power.

Vim has a logical, structured command language. When a beginner is learningthe editor she may feel like it is impossible to understand all the keycommands. However, the commands stack together in a logical way so that overtime the editor becomes predictable.

Setup Tmux with Vim for Mac Posted by Ha.Minh in Productivity Why Tmux. When working on the Mac Terminal, I used to create multiple tabs. Then I can switch quickly between tabs using Ctrl + Shift + and Ctrl + Shift +. While this works smoothly, one annoying. The following steps are used to install Vim on MacOS. 1) Download the latest version To install Vim editor on MacOS, we have to download its latest version by visiting the official website I.e. 2) Mount the disk image file. Enjoy the videos and music you love, upload original content, and share it all with friends, family, and the world on YouTube.

It fixes many of the inconveniences of vanilla vim including. A single config can be used across Windows, Mac and linux; Eliminates swap and backup files from littering directories, preferring to store in a central location. Fixes common typos like:W,:Q, etc; Setup a solid set of settings for Formatting (change to meet your needs). To install the latest version, use homebrew: brew install vim The Ultimate vimrc. The Ultimate vimrc it's a collection of vimrc configurations to make easy the usage of vim. To download the The Ultimate vimrc, you need to install the git client. If you need install it, use home brew: brew install git Now, download the vimrc files.

Configuring Vim with a Vimrc file

The Vimrc file is used to configure the Vim editor. A Vimrc file can rangefrom nothing in it to very complicated with hundreds or thousands of linesof configuration commands.

Here's a short, commented example .vimrc file I use for Python developmentto get a feel for some of the configuration statements:

Here is how these configuration options look with a dark background onMac OS X while editing the markdown for this webpage (how meta!).

Take a look at another example using these configuration options, this timewith a light background and editing Python code from myChoose Your Own Adventures Presentationsproject.

The Vimrc file lives under the home directory of the user account runningVim. For example, when my user account is 'matt', on Mac OS X my Vimrcfile is found at /Users/matt/.vimrc. On Ubuntu Linux my .vimrc filecan be found within the /home/matt/ directory.

If a Vimrc file does not already exist, just create it within the user'shome directory and it will be picked up by Vim the next time you open theeditor.

The following are a few resources for learning what to put in, and how tostructure a .vimrc file. I recommend adding configuration options oneat a time to test them individually instead of going whole hog with a Vimrcyou are unfamiliar with.

Vim tutorials

Vim has a reputation for a difficult learning curve, but it's much easierto get started with these tutorials.

For example, in command mode,$ moves to the end of a line.When $ is preceded by d then everything to the end of the line isdeleted. Over time the simple commands become intuitive and thecombinations become more powerful than having distinct commands such asa drop-down menu with a specific option to delete all text until the endof the line.
