expresso.vim

Evaluate text as a math expression and replace it with the result.

Installation

Using vim-plug:

Plug 'm1foley/vim-expresso'

Usage

• g= after selecting text replaces it with the result.

• g= with a motion. For example, g=$ evaluates text from the cursor to the end of the line.
• g== evaluates the current line.

Command mode

• With a range like :1,7Expresso

Common Issues

Expresso uses Vim expressions, so it has the same limitations of @=, the expression register. If none of the numbers have a decimal, it evaluates to a whole number: 3/2 = 1. To force a Float conversion, add a decimal to one of the numbers: 3/2.0 = 1.5
