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
PATHvariable, list missing directories in yourPATH, etc.
Using stack:
> stack setup
...
> stack build
...
To prepare for making a release the following commands might be useful:
> stack build --install-ghc --copy-bins --local-bin-path ..\windows-env-x86 --arch i386
...
> stack build --install-ghc --copy-bins --local-bin-path ..\windows-env-x64 --arch x86_64
...
> stack install
...
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.
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
...
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
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 PATHs, skipping the
confirmation prompt:
> delpath --global -y C:\test
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'...
New value: bar
Continue? (y/n) y
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
