Can variables be removed from a CUDD manager? - binary-decision-diagram

Could anyone please tell me that is it possible to safely remove variables from the manager in CUDD? For example: I register two variable by v1 = Cudd_bddNewVar(manager); and v2 = Cudd_bddNewVar(manager). Can I remove v2 from the manager?

I think that it's not possible to remove a created variable.

Where store or implement global variables ($) in Rails?

I want to use/implement global variables in Rails. I tried the following:
In config/environments/production.rb:
$n_exams_question = 20
In config/environments/development.rb:
$n_exams_question = 3
I want to use different values in production and development. My localserver is not detecting the global variables. Where is the best place to implement it?
Rails does it that way:
https://guides.rubyonrails.org/configuring.html#custom-configuration
In config/environments/production.rb:
config.myGlobalVariable = 'blabla1'
In config/environments/development.rb:
config.myGlobalVariable = 'blabla2'
then use this Anywhere:
Rails.configuration.myGlobalVariable
I don't know if that answers your question or if it's a good practice, but I would have used the environment variables.
To do this, I use the gem Figaro
Example :
In your application.yml file
development:
N_EXAMS_QUESTION: "15" # ENV['N_EXAMS_QUESTION']
production:
N_EXAMS_QUESTION: "20" # ENV['N_EXAMS_QUESTION']
You can call this value with ENV['N_EXAMS_QUESTION']

Postman - Nested Environment Variables

I'm looking for a way to make environment variables in Postman, that contain other variables. For example: {Server}=localhost;{Port}=9200;{ServerUrl}={Server}:{Port}.
Like in Make...
This way it doesn't seem to work with Postman.
EDIT:
My attempt:
You could do it but I wouldn't recommend it, just seem like you're missing the benefit creating a set of variables and then changing the values of these by selecting a different environment file.
Add this string {{ElasticsearchProtocol}}://{{ElasticsearchServer}}:{{ElasticsearchPort}} as the ElasiticsearchUrl variable, on the environment file.
Or you could add this to the Pre-Request Script:
let ElasticsearchProtocol = pm.environment.get('ElasticsearchProtocol')
let ElasticsearchServer = pm.environment.get('ElasticsearchServer')
let ElasticsearchPort = pm.environment.get('ElasticsearchPort')
pm.environment.set("ElasticsearchUrl", `${ElasticsearchProtocol}://${ElasticsearchServer}:${ElasticsearchPort}`)

Using a defined global variable in a collection variable

I have the following setup:
A global variable api_address defined as http://apiproduction.mydomain.com.
A collection variable route_address defined as users/profiles for each collection.
Right now my query look like: {{api_address}}/{{route_address}}/004ba492-d021-40fe-ba23-f1d366036af4 if i want to get the resource.
So my question is... Could you include in a collection variable a global one?
Example: {{route_address}} could be defined as {{api_address}}/users/profiles.
Yes you can do this! But you have to do it with pre-request scripts.
Edit your selection and go to the pre-request script tab.
Add something like the following:
let api_address = pm.globals.get("api_address");
pm.variables.set("route_address", `${api_address}/users/profile`);
That should give you your "route_address" that you are looking to variablize.
You can probably to the pm.globals.get inline on your set, but I'm old school and think it's cleaner and easier to read if you throw it into a local variable first.

Can I create my own variable which should work like built in variable in Informatica

I want to create my own variable and want to set my default value which should work like a built in variable in Informatica. I want to use created variable in my all workflow.
Is it possible any way ?
Thanks
You can use the same parameter file across all of your mappings (there is syntax to separate out bits which are for specific sections and those which are universal by way of the scope) see following link https://network.informatica.com/thread/27560

initiate a variable dynamically to work in all session on workflow

I am developing an Informaticajob with multiple sessions in one workflow. I need to assign a variable ##AAR with following code
IIF(get_date_part(sysdate,'mm') <= 7, get_date_part(add_to_date(sysdate,'YY',-2),'YY'), get_date_part(add_to_date(sysdate,'YY',-1),'YY')
)
I am not sure how to get about it, I was thinking on creating a session that assigns the variable, then passes it to the workflow.
This session should be the first session to run in the workflow. but I don't know how to create a session that is not a mapping.
What could I do to get this done?
First, you define the variables in your workflow (Workflows -> Edit -> Variables) so the workflow knows about the variables.
Then, as first Task in your workflow, you take an "Assignment" instead of a session. That's the icon that looks like a calculator.
In the assignment, you can assign values to your variables.
Please note that the variables need to be names "$$..." not "##..."
