// Display some additional information atomsSetConfig("Verbose","True"); // Load the test repository exec("SCI/modules/atoms/tests/unit_tests/atomsTestUtils.sce", -1); repository = atomsCreateTestRepository("scene10"); // Install the needed module for the purpose of the example atomsInstall("toolbox_5V6","user"); // simplest way atomsIsInstalled("toolbox_5V6"); // Check several modules ... atomsIsInstalled(["toolbox_5V6" "toolbox_4V6"]) // ... with a specific version atomsIsInstalled(["toolbox_5V6" "1.0" ; "toolbox_4V6" "1.0" ; "toolbox_V65" "1.1"]) // ... installed in a specific section atomsIsInstalled(["toolbox_5V6" "1.0" ; "toolbox_4V6" "1.0" ; "toolbox_5V6" "1.1"],"user") atomsIsInstalled(["toolbox_5V6" "1.0" ; "toolbox_4V6" "1.0" ; "toolbox_5V6" "1.1"],"allusers") // Cleaning atomsRemove(["toolbox_1V6"; ..
