Simple License Manager application to manage file based or env variable based licenses
Some software gives out individual license files when buying multiple licences.
Such software usually requires a ENV variable to point to the license file. i.e.
SOME_SOFTWARE_LICENSE = "path/to/some_software/license.key"
To aid in using multiple licenses in a studio environement slm was created. It's a simple command line tool to aid in file based license key management.
- A Network folder to use as license repository
- License files
- A launcher or batch script to launch the software needing a license key file so that slm can be used to get a license key file and set up the environement prior to starting the application
- Python v2.7+ or 3.6+
A license repository is simply a folder with license files inside it. These could be .lic files or any other types of files.
Check the repo for available license files, displays a list of used and unused licenses in the specified repo.
slm.py -check -licenserepo:"PATH/TO/LICENSE/FILES"
When a license is in use the file will be renamed to .inuse.hostname This command will reset all files in the license repository to their original name and therefore "clear" them from being in use.
slm.py -reset -licenserepo:"PATH/TO/LICENSE/FILES"
Attempts to get a license from the license repository, then sets the specified env var to the license path, starts the executable and waits for it to exit. After exitting the application the license will be "returned" automatically. If a license is already in use by the current computer (i.e. we start the aplication multiple times) the subsequent application starts will consume the existing license and the original session that got the license will be the one to return the license.
slm.py -get -licenserepo:"PATH/TO/LICENSE/FILES" -env:ENVIRONEMENT_VAR_NAME -exe:"PATH/TO/APPLICATION/EXECUTABLE.exe"
