A Rust library to enable getting terminal sizes and dimensions



First, add the following to your Cargo.toml:

term_size = "1"

Next, add this to your crate root:

extern crate term_size;

To get the dimensions of your terminal window, simply use the following:

fn main() {
  if let Some((w, h)) = term_size::dimensions() {
    println!("Width: {}\nHeight: {}", w, h);
  } else {
    println!("Unable to get term size :(")

Minimum Version of Rust

term_size will officially support current stable Rust, minus two releases, but may work with prior releases as well. For example, current stable Rust at the time of this writing is 1.22.1, meaning term_size is guaranteed to compile with 1.20.0 and newer.

At the 1.23.0 stable release, term_size will be guaranteed to compile with 1.21.0 and newer, etc.

Upon bumping the minimum version of Rust (assuming it's within the stable-2 range), it must be clearly annotated in the CHANGELOG.md

Breaking Changes

term_size takes a similar policy to Rust and will bump the major version number upon breaking changes with only the following exceptions:

  • The breaking change is to fix a security concern
  • The breaking change is to be fixing a bug (i.e. relying on a bug as a feature)
  • The breaking change is a feature isn't used in the wild, or all users of said feature have given approval prior to the change
