§Env Var Helpers

Macros and functions that help provide access to environment variable values.


use env_var_helpers::cargo::crates::*;

println!("{}\n", cargo_env());

println!("{}\n", cargo_pkg_version_env());

println!("{}\n", cargo_pkg_name_env());

println!("{}\n", cargo_pkg_readme_env());

§Compiler:

Build with the latest stable compiler.

§Todo:

Add more documentation
Add more functions

§Coding Style

This project uses a coding style the emphasises the use of white space over keeping the line and column counts as low as possible.

So this:

fn bar() {}

fn foo()
{

    bar();

}

Not this:

fn bar() {}

fn foo()
{
    bar();
}
