Windows environment variables ============================= A collection of simple programs to manage environment variables on Windows, created mainly to: * learn a bit of Haskell, * make it easier to add paths to the `PATH` variable, automatically setup `_NT_SYMBOL_PATH`, etc. Building -------- Using [stack]: ``` > stack setup ... > stack build ``` [stack]: http://docs.haskellstack.org/en/stable/README/ Installation ------------ ``` > stack install ``` Usage ----- The complete list of utilities is given below. * [list_path] — List directories in your `PATH`. * [add_path] — Add directories to your `PATH`. * [remove_path] — Remove directories from your `PATH`. * [set_env] — Set environment variables. * [unset_env] — Unset environment variables. Pass the `--help` flag to a utility to examine its detailed usage information. Some examples are given below. [list_path]: #list_path [add_path]: #add_path [remove_path]: #remove_path [set_env]: #set_env [unset_env]: #unset_env ### list_path List directories in your `PATH` variable: ``` > list_path C:\Program Files\Haskell\bin C:\Program Files\Haskell Platform\8.0.1\lib\extralibs\bin C:\Program Files\Haskell Platform\8.0.1\bin C:\Users\Egor\AppData\Roaming\local\bin C:\Users\Egor\AppData\Roaming\cabal\bin ... ``` ``` > list_path --missing C:\Users\Egor\AppData\Roaming\cabal\bin ... ``` ### add_path Add "C:\test" to current user's `PATH`: ``` > add_path C:\test Saving variable 'PATH' to 'HKCU\Environment'... Old value: C:\Users\Egor\AppData\Roaming\local\bin;C:\Users\Egor\AppData\Roaming\cabal\bin New value: C:\Users\Egor\AppData\Roaming\local\bin;C:\Users\Egor\AppData\Roaming\cabal\bin;C:\test Continue? (y/n) y > ``` ### remove_path Remove "C:\test" from both current user's and global `PATH`s, skipping the confirmation prompt: ``` > remove_path --global -y C:\test ``` ### set_env Assign `bar` to the variable `foo` for all users: ``` > set_env -g foo bar Saving variable 'foo' to 'HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Environment'... Value: bar Continue? (y/n) y > ``` ### unset_env Unset the variable `foo` for current user, skipping the confirmation prompt: ``` > unset_env --yes foo ``` License ------- This project, including all of the files and their contents, is licensed under the terms of the MIT License.
