Scripting API Guide

This document provides the information necessary to write test procedures using the COSMOS scripting API. Scripting in COSMOS is designed to be simple and intuitive. The code completion ability for command and telemetry mnemonics makes Script Runner the ideal place to write your procedures, however any text editor will do. If there is functionality that you don't see here or perhaps an easier syntax for doing something, please submit a ticket.

Concepts

Programming Languages

COSMOS scripting is implemented using either Ruby or Python. Ruby and Python are very similar scripting languages and in many cases the COSMOS APIs are identical between the two. This guide is written to support both with additional language specific information found in the Script Writing Guide.

Using Script Runner

Script Runner is a graphical application that provides the ideal environment for running and implementing your test procedures. The Script Runner tool is broken into 4 main sections. At the top of the tool is a menu bar that allows you to do such things as open and save files, perform a syntax check, and execute your script.

Next is a tool bar that displays the currently executing script and three buttons, "Start/Go", "Pause/Retry", and "Stop". The Start/Go button is used to start the script and continue past errors or waits. The Pause/Retry button will pause the executing script. If an error is encountered the Pause button changes to Retry to re-execute the errored line. Finally, the Stop button will stop the executing script at any time.

Third is the display of the actual script. While the script is not running, you may edit and compose scripts in this area. A handy code completion feature is provided that will list out the available commands or telemetry points as you are writing your script. Simply begin writing a cmd( or tlm( line to bring up code completion. This feature greatly reduces typos in command and telemetry mnemonics.

Finally, the bottom of the display is the log messages. All commands that are sent, errors that occur, and user print statements appear in this area.

Telemetry Types

There are four different ways that telemetry values can be retrieved in COSMOS. The following chart explains their differences.

Telemetry Type	Description
Raw	Raw telemetry is exactly as it is in the telemetry packet before any conversions. All telemetry items will have a raw value except for Derived telemetry points which have no real location in a packet. Requesting raw telemetry on a derived item will return nil.
Converted	Converted telemetry is raw telemetry that has gone through a conversion factor such as a state conversion or a polynomial conversion. If a telemetry item does not have a conversion defined, then converted telemetry will be the same as raw telemetry. This is the most common type of telemety used in scripts.
Formatted	Formatted telemetry is converted telemetry that has gone through a printf style conversion into a string. Formatted telemetry will always have a string representation. If no format string is defined for a telemetry point, then formatted telemetry will be the same as converted telemetry except represented as string.
Formatted with Units	Formatted with Units telemetry is the same as Formatted telemetry except that a space and the units of the telemetry item are appended to the end of the string. If no units are defined for a telemetry item then this type is the same as Formatted telemetry.

Script Runner API

The following methods are designed to be used in Script Runner procedures. Many can also be used in custom built COSMOS tools. Please see the COSMOS Tool API section for methods that are more efficient to use in custom tools.

Retrieving User Input

These methods allow the user to enter values that are needed by the script.

ask

Prompts the user for input with a question. User input is automatically converted from a string to the appropriate data type. For example if the user enters "1", the number 1 as an integer will be returned.

Ruby / Python Syntax:

ask("<question>", <Blank or Default>, <Password>)

Parameter	Description
question	Question to prompt the user with.
Blank or Default	Whether or not to allow empty responses (optional - defaults to false). If a non-boolean value is passed it is used as a default value.
Password	Whether to treat the entry as a password which is displayed with dots and not logged. Default is false.

Ruby Example:

value = ask("Enter an integer")
value = ask("Enter a value or nothing", true)
value = ask("Enter a value", 10)
password = ask("Enter your password", false, true)

Python Example:

value = ask("Enter an integer")
value = ask("Enter a value or nothing", True)
value = ask("Enter a value", 10)
password = ask("Enter your password", False, True)

ask_string

Prompts the user for input with a question. User input is always returned as a string. For example if the user enters "1", the string "1" will be returned.

Ruby / Python Syntax:

ask_string("<question>", <Blank or Default>, <Password>)

Parameter	Description
question	Question to prompt the user with.
Blank or Default	Whether or not to allow empty responses (optional - defaults to false). If a non-boolean value is passed it is used as a default value.
Password	Whether to treat the entry as a password which is displayed with dots and not logged. Default is false.

Ruby Example:

string = ask_string("Enter a String")
string = ask_string("Enter a value or nothing", true)
string = ask_string("Enter a value", "test")
password = ask_string("Enter your password", false, true)

Python Example:

string = ask_string("Enter a String")
string = ask_string("Enter a value or nothing", True)
string = ask_string("Enter a value", "test")
password = ask_string("Enter your password", False, True)

message_box

vertical_message_box

combo_box

The message_box, vertical_message_box, and combo_box methods create a message box with arbitrary buttons or selections that the user can click. The text of the button clicked is returned.

Ruby / Python Syntax:

message_box("<Message>", "<button text 1>", ...)
vertical_message_box("<Message>", "<button text 1>", ...)
combo_box("<Message>", "<selection text 1>", ...)

Parameter	Description
Message	Message to prompt the user with.
Button/Selection Text	Text for a button or selection

Ruby Example:

value = message_box("Select the sensor number", 'One', 'Two')
value = vertical_message_box("Select the sensor number", 'One', 'Two')
value = combo_box("Select the sensor number", 'One', 'Two')
case value
when 'One'
  puts 'Sensor One'
when 'Two'
  puts 'Sensor Two'
end

Python Example:

value = message_box("Select the sensor number", 'One', 'Two')
value = vertical_message_box("Select the sensor number", 'One', 'Two')
value = combo_box("Select the sensor number", 'One', 'Two')
match value:
    case 'One':
        print('Sensor One')
    case 'Two':
        print('Sensor Two')

get_target_file

Return a file handle to a file in the target directory

Ruby Syntax:

get_target_file("<File Path>", original: false)

Python Syntax:

get_target_file("<File Path>", original=False)

Parameter	Description
File Path	The path to the file in the target directory. Should assume to start with a TARGET name, e.g. INST/procedures/proc.rb
original	Whether to get the original file from the plug-in, or any modifications to the file. Default is false which means to grab the modified file. If the modified file does not exist the API will automatically try to pull the original.

Ruby Example:

file = get_target_file("INST/data/attitude.bin")
puts file.read().formatted # format a binary file
file.unlink # delete file
file = get_target_file("INST/procedures/checks.rb", original: true)
puts file.read()
file.unlink # delete file

Python Example:

from openc3.utilities.string import formatted

file = get_target_file("INST/data/attitude.bin")
print(formatted(file.read())) # format a binary file
file.close() # delete file
file = get_target_file("INST/procedures/checks.rb", original=True)
print(file.read())
file.close() # delete file

put_target_file

Writes a file to the target directory

Ruby or Python Syntax:

put_target_file("<File Path>", "IO or String")

Parameter	Description
File Path	The path to the file in the target directory. Should assume to start with a TARGET name, e.g. INST/procedures/proc.rb. The file can previously exist or not. Note: The original file from the plug-in will not be modified, however existing modified files will be overwritten.
IO or String	The data can be an IO object or String

Ruby Example:

put_target_file("INST/test1.txt", "this is a string test")
file = Tempfile.new('test')
file.write("this is a Io test")
file.rewind
put_target_file("INST/test2.txt", file)
put_target_file("INST/test3.bin", "\x00\x01\x02\x03\xFF\xEE\xDD\xCC") # binary

Python Example:

put_target_file("INST/test1.txt", "this is a string test")
file = tempfile.NamedTemporaryFile(mode="w+t")
file.write("this is a Io test")
file.seek(0)
put_target_file("INST/test2.txt", file)
put_target_file("INST/test3.bin", b"\x00\x01\x02\x03\xFF\xEE\xDD\xCC") # binary

delete_target_file

Delete a file in the target directory

Ruby / Python Syntax:

delete_target_file("<File Path>")

Parameter	Description
File Path	The path to the file in the target directory. Should assume to start with a TARGET name, e.g. INST/procedures/proc.rb. Note: Only files created with put_target_file can be deleted. Original files from the plugin installation will remain.

Ruby / Python Example:

put_target_file("INST/delete_me.txt", "to be deleted")
delete_target_file("INST/delete_me.txt")

open_file_dialog

open_files_dialog

The open_file_dialog and open_files_dialog methods create a file dialog box so the user can select a single or multiple files. The selected file(s) is returned.

Note: COSMOS 5 has deprecated the save_file_dialog and open_directory_dialog methods. save_file_dialog can be replaced by put_target_file if you want to write a file back to the target. open_directory_dialog doesn't make sense in new architecture so you must request individual files.

Ruby Syntax:

open_file_dialog("<Title>", "<Message>", filter: "<filter>")
open_files_dialog("<Title>", "<Message>", filter: "<filter>")

Python Syntax:

open_file_dialog("<Title>", "<Message>", filter="<filter>")
open_files_dialog("<Title>", "<Message>", filter="<filter>")

Parameter	Description
Title	The title to put on the dialog. Required.
Message	The message to display in the dialog box. Optional parameter.
filter	Named parameter to filter allowed file types. Optional parameter, specified as comma delimited file types, e.g. ".txt,.doc". See https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input/file#accept for more information.

Ruby Example:

file = open_file_dialog("Open a single file", "Choose something interesting", filter: ".txt")
puts file # Ruby File object
puts file.read
file.delete

files = open_files_dialog("Open multiple files") # message is optional
puts files # Array of File objects (even if you select only one)
files.each do |file|
  puts file
  puts file.read
  file.delete
end

Python Example:

file = open_file_dialog("Open a single file", "Choose something interesting", filter=".txt")
print(file)
print(file.read())
file.close()

files = open_files_dialog("Open multiple files") # message is optional
print(files) # Array of File objects (even if you select only one)
for file in files:
    print(file)
    print(file.read())
    file.close()

Handling Telemetry

These methods allow the user to interact with telemetry items.

check, check_raw, check_formatted, check_with_units

Performs a verification of a telemetry item using its specified telemetry type. If the verification fails then the script will be paused with an error. If no comparison is given to check then the telemetry item is simply printed to the script output. Note: In most cases using wait_check is a better choice than using check.

Ruby / Python Syntax:

check("<Target Name> <Packet Name> <Item Name> <Comparison - optional>")

Parameter	Description
Target Name	Name of the target of the telemetry item.
Packet Name	Name of the telemetry packet of the telemetry item.
Item Name	Name of the telemetry item.
Comparison	A comparison to perform against the telemetry item. If a comparison is not given then the telemetry item will just be printed into the script log.

Ruby Example:

check("INST HEALTH_STATUS COLLECTS > 1")
check_raw("INST HEALTH_STATUS COLLECTS > 1")
check_formatted("INST HEALTH_STATUS COLLECTS > 1")
check_with_units("INST HEALTH_STATUS COLLECTS > 1")
# Ruby passes type as symbol
check("INST HEALTH_STATUS COLLECTS > 1", type: :RAW)

Python Example:

check("INST HEALTH_STATUS COLLECTS > 1")
check_raw("INST HEALTH_STATUS COLLECTS > 1")
check_formatted("INST HEALTH_STATUS COLLECTS > 1")
check_with_units("INST HEALTH_STATUS COLLECTS > 1")
# Python passes type as string
check("INST HEALTH_STATUS COLLECTS > 1", type='RAW')

check_tolerance

Checks a converted telemetry item against an expected value with a tolerance. If the verification fails then the script will be paused with an error. Note: In most cases using wait_check_tolerance is a better choice than using check_tolerance.

Ruby / Python Syntax:

check_tolerance("<Target Name> <Packet Name> <Item Name>", <Expected Value>, <Tolerance>)

Parameter	Description
Target Name	Name of the target of the telemetry item.
Packet Name	Name of the telemetry packet of the telemetry item.
Item Name	Name of the telemetry item.
Expected Value	Expected value of the telemetry item.
Tolerance	± Tolerance on the expected value.
type	CONVERTED (default) or RAW (Ruby symbol, Python string)

Ruby Example:

check_tolerance("INST HEALTH_STATUS COLLECTS", 10.0, 5.0)
check_tolerance("INST HEALTH_STATUS TEMP1", 50000, 20000, type: :RAW)

Python Example:

check_tolerance("INST HEALTH_STATUS COLLECTS", 10.0, 5.0)
check_tolerance("INST HEALTH_STATUS TEMP1", 50000, 20000, type='RAW')

check_expression

Evaluates an expression. If the expression evaluates to false the script will be paused with an error. This method can be used to perform more complicated comparisons than using check as shown in the example. Note: In most cases using wait_check_expression is a better choice than using check_expression.

Remember that everything inside the check_expression string will be evaluated directly and thus must be valid syntax. A common mistake is to check a variable like so (Ruby variable interpolation):

check_expression("#{answer} == 'yes'") # where answer contains 'yes'

This evaluates to yes == 'yes' which is not valid syntax because the variable yes is not defined (usually). The correct way to write this expression is as follows:

check_expression("'#{answer}' == 'yes'") # where answer contains 'yes'

Now this evaluates to 'yes' == 'yes' which is true so the check passes.

Ruby Syntax:

check_expression(exp_to_eval, context = nil)

Python Syntax:

check_expression(exp_to_eval, globals=None, locals=None)

Parameter	Description
exp_to_eval	An expression to evaluate.
context (ruby only)	The context to call eval with. Defaults to nil. Context in Ruby is typically binding() and is usually not needed.
globals (python only)	The globals to call eval with. Defaults to None. Note that to use COSMOS APIs like tlm() you must pass globals().
locals (python only)	The locals to call eval with. Defaults to None. Note that if you're using local variables in a method you must pass locals().

Ruby Example:

check_expression("tlm('INST HEALTH_STATUS COLLECTS') > 5 and tlm('INST HEALTH_STATUS TEMP1') > 25.0")

Python Example:

def check(value):
    # Here we using both tlm() and a local 'value' so we need to pass globals() and locals()
    check_expression("tlm('INST HEALTH_STATUS COLLECTS') > value", 5, 0.25, globals(), locals())
check(5)

check_exception

Executes a method and expects an exception to be raised. If the method does not raise an exception, a CheckError is raised.

Ruby / Python Syntax:

check_exception("<Method Name>", "<Method Params - optional>")

Parameter	Description
Method Name	The COSMOS scripting method to execute, e.g. 'cmd', etc.
Method Params	Parameters for the method

Ruby Example:

check_exception("cmd", "INST", "COLLECT", "TYPE" => "NORMAL")

Python Example:

check_exception("cmd", "INST", "COLLECT", {"TYPE": "NORMAL"})

tlm, tlm_raw, tlm_formatted, tlm_with_units

value = tlm_raw("INST HEALTH_STATUS COLLECTS")
value = tlm_formatted("INST HEALTH_STATUS COLLECTS")
value = tlm_with_units("INST HEALTH_STATUS COLLECTS")
# Equivalent to tlm_raw
raw_value = tlm("INST HEALTH_STATUS COLLECTS", type: :RAW)

Python Example:

value = tlm("INST HEALTH_STATUS COLLECTS")
value = tlm("INST", "HEALTH_STATUS", "COLLECTS")
value = tlm_raw("INST HEALTH_STATUS COLLECTS")

Packet Data Subscriptions

APIs for subscribing to specific packets of data. This provides an interface to ensure that each telemetry packet is received and handled rather than relying on polling where some data may be missed.

subscribe_packets

Allows the user to listen for one or more telemetry packets of data to arrive. A unique id is returned which is used to retrieve the data.

Ruby / Python Syntax:

subscribe_packets(packets)

Parameter	Description
packets	Nested array of target name/packet name pairs that the user wishes to subscribe to.

Ruby / Python Example:

id = subscribe_packets([['INST', 'HEALTH_STATUS'], ['INST', 'ADCS']])

get_packets

Delays

These methods allow the user to pause the script to wait for telemetry to change or for an amount of time to pass.

wait

Pauses the script for a configurable amount of time (minimum 10ms) or until a converted telemetry item meets given criteria. It supports three different syntaxes as shown. If no parameters are given then an infinite wait occurs until the user presses Go. Note that on a timeout, wait does not stop the script, usually wait_check is a better choice.

Ruby / Python Syntax:

elapsed = wait() #=> Returns the actual time waited
elapsed = wait(<Time>) #=> Returns the actual time waited

Parameter	Description
Time	Time in Seconds to delay for.

Ruby / Python Syntax:

# Returns true or false based on the whether the expression is true or false
success = wait("<Target Name> <Packet Name> <Item Name> <Comparison>", <Timeout>, <Polling Rate (optional)>, type, quiet)

Parameter	Description
Target Name	Name of the target of the telemetry item.
Packet Name	Name of the telemetry packet of the telemetry item.
Item Name	Name of the telemetry item.
Comparison	A comparison to perform against the telemetry item.
Timeout	Timeout in seconds. Script will proceed if the wait statement times out waiting for the comparison to be true.
Polling Rate	How often the comparison is evaluated in seconds. Defaults to 0.25 if not specified.
type	Named parameter specifying the type. RAW, CONVERTED (default), FORMATTED, WITH_UNITS (Ruby symbol, Python string).
quiet	Named parameter indicating whether to log the result. Defaults to true.

Ruby Example:

elapsed = wait
elapsed = wait 5
success = wait("INST HEALTH_STATUS COLLECTS == 3", 10)
success = wait("INST HEALTH_STATUS COLLECTS == 3", 10, type: :RAW, quiet: false)

Python Example:

elapsed = wait()
elapsed = wait(5)
success = wait("INST HEALTH_STATUS COLLECTS == 3", 10)
success = wait("INST HEALTH_STATUS COLLECTS == 3", 10, type='RAW', quiet=False)

wait_tolerance

Pauses the script for a configurable amount of time or until a converted telemetry item meets equals an expected value within a tolerance. Note that on a timeout, wait_tolerance does not stop the script, usually wait_check_tolerance is a better choice.

Ruby Python Syntax:

# Returns true or false based on the whether the expression is true or false
success = wait_tolerance("<Target Name> <Packet Name> <Item Name>", <Expected Value>, <Tolerance>, <Timeout>, <Polling Rate (optional), type, quiet>)

success = wait_tolerance("INST HEALTH_STATUS COLLECTS", 10.0, 5.0, 10, type='RAW', quiet=True)

wait_expression

Pauses the script until an expression is evaluated to be true or a timeout occurs. If a timeout occurs the script will continue. This method can be used to perform more complicated comparisons than using wait as shown in the example. Note that on a timeout, wait_expression does not stop the script, usually wait_check_expression is a better choice.

Ruby Syntax:

# Return true or false based the expression evaluation
wait_expression(
  exp_to_eval,
  timeout,
  polling_rate = DEFAULT_TLM_POLLING_RATE,

Ruby Example:

success = wait_expression("tlm('INST HEALTH_STATUS COLLECTS') > 5 and tlm('INST HEALTH_STATUS TEMP1') > 25.0", 10, 0.25, nil, quiet: true)

Python Example:

def check(value):
    # Here we using both tlm() and a local 'value' so we need to pass globals() and locals()

Jumps to a specific line in either the current file or another file. Script context and local variables are retained if jumping in the same file. This method should not be used to create loops or in any other case where normal Python/Ruby functionality could perform the same function. Use of goto increases stack depth and excess use can lead to stack level too deep errors.

Ruby / Python Syntax:

goto(line_number)
goto(filename, line_number)

Parameter	Description
Line Number or Procedure Filename	If this is the only argument given then it is the line number to goto in the same script. If two arguments are given, then it is the filename to goto
Line Number	If the second argument, it is the line number in the filename given by the first argument to goto

Ruby / Python Example:

goto(23)
goto("TARGET/procedures/other_script.rb", 5)
goto("TARGET/procedures/other_script.py", 12)

load_utility

Reads in a script file that contains useful subroutines for use in your test procedure. When these subroutines run in ScriptRunner or TestRunner, their lines will be highlighted. If you want to import subroutines but do not want their lines to be highlighted in ScriptRunner or TestRunner, use the standard Ruby 'load' or 'require' statement or Python 'import' statement.

Ruby / Python Syntax:

load_utility("TARGET/lib/<Utility Filename>")

Parameter	Description
Utility Filename	Name of the script file containing subroutines including the .rb or .py extension. You need to include the full target name and path such as TARGET/lib/utility.rb

Ruby / Python Example:

load_utility("TARGET/lib/mode_changes.rb") # Ruby
load_utility("TARGET/lib/mode_changes.py") # Python

script_list

Returns all the available files in COSMOS as an array / list. This includes configuration files at every directory level to ensure the user has access to every file. You can filter the list client side to just the 'lib' and or 'procedures' directories if you wish. Note: script names do NOT include '*' to indicate modified.

Ruby Example:

scripts = script_list()
puts scripts.length #=> 139
puts scripts.select {|script| script.include?('/lib/') || script.include?('/procedures/')} #=>
# [EXAMPLE/lib/example_interface.rb, INST/lib/example_limits_response.rb, ...]

Python Example:

scripts = script_list()
print(len(scripts))
print(list(script for script in scripts if '/lib/' in script or '/procedures/' in script)) #=>
# [EXAMPLE/lib/example_interface.rb, INST/lib/example_limits_response.rb, ...]

Ruby / Python Syntax:

script_delete("<Script Name>")

Parameter	Description
Script Name	Full path name of the script starting with the target

Ruby / Python Example:

script_delete("INST/procedures/checks.rb")

script_run

disable_instrumentation

Disables instrumentation for a block of code (line highlighting and exception catching). This is especially useful for speeding up loops that are very slow if lines are instrumented. Consider breaking code like this into a separate file and using either require/load to read the file for the same effect while still allowing errors to be caught by your script.

Use with Caution

Disabling instrumentation will cause any error that occurs while disabled to cause your script to completely stop.

Ruby Example:

disable_instrumentation do
  1000.times do
    # Don't want this to have to highlight 1000 times
  end
end

Python Example:

with disable_instrumentation():
    for x in range(1000):
        # Don't want this to have to highlight 1000 times

Script Runner Suites

Creating Script Runner suites utilizes APIs to add groups to the defined suites. For more information please see running script suites.

add_group, add_group_setup, add_group_teardown, add_script

Adds a group's methods to the suite. The add_group method adds all the group methods including setup, teardown, and all the methods starting with 'script_' or 'test_'. The add_group_setup method adds just the setup method defined in the group class. The add_group_teardown method adds just the teardown method defined in the group class. The add_script method adds an individual method to the suite. NOTE: add_script can add any method including those not named with 'script_' or 'test_'.

Ruby / Python Syntax:

add_group(<Group Class>)
add_group_setup(<Group Class>)
add_group_teardown(<Group Class>)
add_script(<Group Class>, <Method>)

Parameter	Description
Group Class	Name of the previously defined class which inherits from the OpenC3 Group class. The Ruby API passes a String with the name of the group. The Python API passes the Group class directly.
Method	Name of the method in the OpenC3 Group class. The Ruby API passes a String with the name of the method. The Python API passes the Group class directly.

Ruby Example:

load 'openc3/script/suite.rb'

class ExampleGroup < OpenC3::Group
  def script_1
    # Insert test code here ...
  end
end
class WrapperGroup < OpenC3::Group
  def setup
    # Insert test code here ...
  end
  def my_method
    # Insert test code here ...
  end
  def teardown
    # Insert test code here ...
  end
end

class MySuite < OpenC3::Suite
  def initialize
    super()
    add_group('ExampleGroup')
    add_group_setup('WrapperGroup')
    add_script('WrapperGroup', 'my_method')
    add_group_teardown('WrapperGroup')
  end
end

Python Example:

from openc3.script import *
from openc3.script.suite import Group, Suite

class ExampleGroup(Group):
    def script_1(self):
        # Insert test code here ...
        pass
class WrapperGroup(Group):
    def setup(self):
        # Insert test code here ...
        pass
    def my_method(self):
        # Insert test code here ...
        pass
    def teardown(self):
        # Insert test code here ...
        pass
class MySuite(Suite):
    def __init__(self):
        super().__init__()
        self.add_group(ExampleGroup)
        self.add_group_setup(WrapperGroup)
        self.add_script(WrapperGroup, 'my_method')
        self.add_group_teardown(WrapperGroup)

Offline Access

An offline access token is required to execute scripts in COSMOS Enterprise. These methods support client side creation, testing, and setting of the offline_access_token.

initialize_offline_access

Creates and sets the offline access token for the user. Note: calling this method is required before executing any api methods that require an offline access token like script_run (Enterprise Only). This method must be called OUTSIDE of ScriptRunner as it is needed in order to start a script in the first place.

Ruby Example:

# First setup environment variables. See examples/external_script.rb
initialize_offline_access()
script_run("INST/procedures/collect.rb")

Python Example:

# First setup environment variables. See examples/external_script.py
initialize_offline_access()
script_run("INST2/procedures/collect.py")

offline_access_needed

Returns true if the user needs to generate an offline access token. Note this will only be true if the user is at least authorized to view scripts, otherwise it will always be false if script_view permission is not available for the user.

Ruby Example:

result = offline_access_needed() #=> true

Python Example:

result = offline_access_needed() #=> False

set_offline_access

Sets the offline access token in the backend. Note: You probably don't need to call this method directly, as it will be called by initialize_offline_access().

Ruby / Python Syntax:

set_offline_access(offline_access_token)

Parameter	Description
offline_access_token	Keycloak generated refresh token that contains the offline_access openid scope

Ruby / Python Example:

set_offline_access(offline_access_token)
