Instead of stripping the ANSI formatting characters from our strings, work out the length without them and use that. This is per-column, but most of them are simple (just the same number of characters in the non-coloured string). Sometimes, this is really simple: for example, trwxrwxrwx permissions strings are always going to be ten characters long, and the strings that get returned are chock full of ANSI escape codes. This should have a small benefit on performance.

Installation
exa is written in Rust. You'll have to use the nightly -- I try to keep it up to date with the latest version when possible. Once you have it set up, a simple cargo build will pull in all the dependencies and compile exa.
