windows-env

Easily manage Windows environment variables permanently, without the need to restart your system or terminal.

Features:

• Easily operate list variables like PATH.

Note:

• The env operation will affect the current terminal process since v0.2.0.

Installation

• as lib:

  [target."cfg(windows)".dependencies]
  windows_env = "0.2.0"
  

• as executable binary:

  cargo binstall windows-env        # see cargo-binstall: https://github.com/cargo-bins/cargo-binstall
  cargo install windows-env -F bin  # or compile from source manually
  

Example

• binary usage: runs wenv -h to see help message.

• lib usage:

  fn main() -> std::io::Result<()> {
      windows_env::set("TEST_ENV", "test")?;
      assert_eq!(windows_env::get("TEST_ENV")?.unwrap(), "test");
      windows_env::remove("TEST_ENV")?;
      assert!(windows_env::get("TEST_ENV")?.is_none());
  
      windows_env::append("TEST_ENV", "test1")?;
      windows_env::prepend("TEST_ENV", "test2")?;
      assert_eq!(windows_env::get("TEST_ENV")?.unwrap(), "test2;test1");
  
      windows_env::remove_from_list("TEST_ENV", "test2")?;
      assert!(windows_env::exists_in_list("TEST_ENV", "test1")?);
  
      windows_env::remove("TEST_ENV")?;
      Ok(())
  }
