edit temporarily environment variables

injec-env

Console program for Windows to edit user environnement variables temporarily (in HKCU, so no admins rights needed). For when you want to have portable softwares on an USB stick that instantly work using the CLI, for example, or set that damn JAVA_HOME using a jdk on an USB stick.

How to use

First, make sure the files are NOT in an admin rights protected folder.

To use it, create a config file called rules.json next to the Injec Env.exe. If you run the .exe without it, it will create an example for you.

Once done, just start the .exe and it will do its magic. To stop, write exit or Ctrl+C. DO NOT CLOSE THE WINDOW OR KILL THE PROCESS ; doing so will likely not give enough time to revert the changes.

Features :

• Set a new variable, which is deleted once the program stops.
• Set an existing variable, which is reverted once the program stops.
• Add values to the Path variable.
• Does not revert values if the said values has changed while the program was active.
• If you are a dummy dumb and remove the disk the software is running on, it will revert automatically, if it ever keeps running somehow.

Dynamic values

Values will be written differently :

• If you want to set a constant value that is not a path, prefix it with : (example : ":some string" will be saved as some string)
• You can set a relative path, it will be saved as an absolute path depending on the current working directory.
• You can set a kinda relative path : If you give an absolute path, but with no letter (/absolute/path/to/folder), the engine will use the disk letter of the current working directory (ex: E:/absolute/path/to/folder).
• You can, obviously, set absolute paths (ex:C:/path/to/stuff).

Paths will be normalized by replacing / to \\.

Last warning ⚠

The program runs on NET 6.0, so you WILL require, at least, the NET 6.0 runtime (Desktop not needed).

A version of NET 6.0 runtime compatible.

To start the program, you will have to execute the .dll using the dotnet command. For example :

cd "path/to/Injec Env"
path/to/NET6/dotnet.exe "Injec Env.dll"

Or just clone the repo, publish the software with the runtime and you are good to go.
