Can I perform mathematics on a selection in Sublime Text?

Question

Short of writing my own plugin to do so, does there exist a mechanism with which I can add/subtract from multiple selected numbers?

I need to apply the same equation (in this case, subtract 5) to many values; and I'd rather not do it individually. Could this perhaps be a job for another program?

Answer 1

Sublime Calculate evaluates selected text, and looks great for small calculations, especially paired with the replace option: https://github.com/colinta/SublimeCalculate

As stated before, Sublime Evaluate has python evaluation covered: https://github.com/jbrooksuk/Sublime-Evaluate

Answer 2

There's plugin called Sublime-Evaluate which allows you to evaluate bits of Python, and output it straight into your buffer. For example, [i for i in range(5)] evaluated turns itself into [0, 1, 2, 3, 4]. That can be used for arithmetic operations as well, just use those multiple selections and write +5 after each value, then select it all and evaluate. The plugin usually screws positions of your cursors, don't get confused by that.

Answer 3

If you already use Emmet (which I highly suggest), use its Evaluate Math function. No need to install more plugins. Only issue is that it cuts the result at 2 decimal digits.
