Environment Variables

What are environment variables?

Every program on Linux has an environment, like a bash- or zsh-shell, that it runs in. These shells can contain variables that can change how OmniOpt2 works. Here is a list of all shell variables that change how OmniOpt2 works.
It is important that you run these commands before you run OmniOpt2, and also that you write export in front of them. Unexported variables are not passed to programs started by the shell.

Name	What does it do?
OmniOpt2
`export install_tests=1`	Install test modules
`export RUN_UUID=$(uuidgen)`	Sets the UUID for the run. Default is a new one via `uuidgen`
`export OO_NO_LOGO=1`	Disables showing the logo
`export OO_MAIN_TESTS=1`	Sets the user-id to `affed00faffed00faffed00faffed00f`, so the statistics can determine whether you are a real user or a test-user
`export ITWORKSONMYMACHINE=1`	Sets the user-id to `affeaffeaffeaffeaffeaffeaffeaffe`, so the statistics can determine whether you are a real user or a the main developer (only I should set this variable)
`export root_venv_dir=/path/to/venv`	Path to where virtualenv should be installed. Default is `$HOME`
`export DISABLE_SIXEL_GRAPHICS=1`	Disables sixel-graphics, no matter what other parameters are set
`export DONT_INSTALL_MODULES=1`	Disables installing modules
`export DONT_SHOW_DONT_INSTALL_MESSAGE=1`	Don't show messages regarding the installation of modules
`export DONTSTARTFIREFOX=1`	Don't start firefox when `RUN_WITH_COVERAGE` is defined.
`export RUN_WITH_COVERAGE=1`	Runs omniopt- and plot-script with coverage to find out test code coverage
`export CI=1`	Disables certain tests in a CI environment
`export PRINT_SEPERATOR=1`	Prints a seperator line after OmniOpt2 runs (useful for automated tests)
Plot-Script
`export BUBBLESIZEINPX=1`	Size of bubbles in plot scripts in px
Test-Scripts
`export CREATE_PLOT_HELPS=1`	Creates the help files for the tutorials page for each `omniopt_plot`

`export NO_TESTS=1`	Disable tests for `.tests/pre-commit`-hook
`export NO_NO_RESULT_ERROR=1`	Disable errors to stdout for plots when no results are found
`export SHOW_COMMAND_BEFORE_EXECUTION=1`	Show `omniopt_plot`-commands before executing them
`export OMNIOPT_CALL="./omniopt"`	How to call OmniOpt2. Is useful to differentiate between pip installs and installs via git.
