Since v2.9.0, RNA Framework exports a number of environment variables, that will allow controlling specific behaviours of the framework.

RF_NOCHECKUPDATES

Description: Disables check for updates from the RNA Framework's git repository at programs' startup.
Accepted values:
 0 (update check enabled) [default]
 1 (update check disabled)

Example:

$ export RF_NOCHECKUPDATES=1     # Disables check for updates

RF_VERBOSITY

Description: Controls the level of verbosity of RNA Framework's warnings and exceptions.
Accepted values:
-1 (no warnings, without stack trace)
 0 (warnings and exceptions, without stack trace) [default]
 1 (warnings and exceptions, with stack trace)

Example:

$ export RF_VERBOSITY=0     # Default, without stack trace

# [!] Exception [Core::Process::Queue->start()]:
#     Data looks binary, but binMode is not set to ":raw"
#     -> Caught at lib/Core/Base.pm line 118.



$ export RF_VERBOSITY=1     # With stack trace

# [!] Exception [Core::Process::Queue->start()]:
#     Data looks binary, but binMode is not set to ":raw"
#
#     Stack dump (descending):
#
#     [*] Package:    main
