Windows environment variables ============================= A collection of simple utilities to manage Windows environment variables, created mainly to: * learn a bit of Haskell, * make it easier to add directories to the `PATH` variable, list missing directories in your `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. * [paths] — List directories in your `PATH`. * [addpath] — Add directories to `PATH`. * [delpath] — Remove directories from `PATH`. * [setenv] — Assign values to environment variables. * [delenv] — Delete environment variables. Pass the `--help` flag to an utility to examine its detailed usage information. Some examples are given below. [paths]: #paths [addpath]: #addpath [delpath]: #delpath [setenv]: #setenv [delenv]: #delenv ### paths List directories in your `PATH`: ``` > paths 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 ... ``` Only list missing directories in your `PATH`: ``` > paths --missing C:\Users\Egor\AppData\Roaming\cabal\bin ... ``` ### addpath Add "C:\test" to current user's `PATH`: ``` > addpath 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 ``` Add "C:\test" to the global `PATH`, skipping the confirmation prompt: ``` > addpath --global -y C:\test ``` ### delpath Remove "C:\test" from current user's `PATH`: ``` > delpath C:\test Saving variable 'PATH' to 'HKCU\Environment'... Old value: C:\Users\Egor\AppData\Roaming\local\bin;C:\Users\Egor\AppData\Roaming\cabal\bin;C:\test New value: C:\Users\Egor\AppData\Roaming\local\bin;C:\Users\Egor\AppData\Roaming\cabal\bin ``` Remove "C:\test" from both current user's and the global `PATH`s, skipping the confirmation prompt: ``` > delpath --global -y C:\test ``` ### setenv Assign `bar` to the variable `foo` in current user's environment, skipping the confirmation prompt: ``` > setenv -y foo bar ``` Assign `bar` to the variable `foo` in the global environment: ``` > setenv --global foo bar Saving variable 'foo' to 'HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Environment'... Value: bar Continue? (y/n) y ``` ### delenv Delete the variable `foo` from current users's environment, skipping the confirmation prompt: ``` > delenv -y foo ``` Delete the variable `foo` from the global environment: ``` > delenv --global foo Deleting variable 'foo' from 'HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Environment'... Continue? (y/n) y ``` License ------- Distributed under the MIT License. See [LICENSE.txt] for details. [LICENSE.txt]: LICENSE.txt
