create-release | An Action to create releases via the GitHub Release API | Continous Integration library

I am trying to create a GitHub Action that is triggered when a release is published and will build my project and upload certain artefacts as release assets. The only examples I can find rely on using the create-release action, which fails as the release has already been created. My workflow file is like so:

I want to upload a artifact to latest release... without creating a new release.

I started with github official action upload-release-asset to upload artifact.
It requires a upload_url as an input which tells it the url of release.
Which is generally taken from creating a release in previous step with create-release action.

I tried to print output url from create_release-

I have a GitHub workflow for releasing nightly snapshots of the repository. It uses the create-release action. This is how the workflow file looks right now:

I have a workflow where after a push to master I want to create a release and upload an asset to it.
I'm using actions/create-release@v1 and actions/upload-release-asset@v1.

I would like to pass the outputs of a bash commands to the action parameters. However I found out the syntax of "$(command)" does not work.

How can I pass the output of a bash command to an action's parameter.

For example I'd like to do something like this:

Currently on my GitHub repository, I have the following workflow that releases a nightly snapshot every day, and uses the current date as release name and tag name:

Background

I'm writing a Github action to upload build artefacts on every new tag created. This have turned out to be fairly strait forward to do.

However I wanted to upload the different variants as separate files to github's release page but couldn't figure out how to use a wildcard for this, and resorted to duplicating this sections with hardcoded filenames instead. To duplicate code with hardcoded filenames is error prone and not very future safe.

I guess the question maybe boils down to how yml works: Could this have been done shorter with some kind of a loop or wildcard?

This is the long code I ended up with:

I'm trying to write a workflow to have my GitHub project release populated by the tag creation workflow.

I already know how to create the release (using actions/create-release@v1.0.0) and how to push an artifact in the release (using actions/upload-release-asset).

But, since I'm building Rust code, I ahve to compile it on different platforms. Obviously, for that, I have one job per platform and I'm trying to push my artifact in that job.

But for the push to work, I have to use the release identifier given by actions/create-release@v1.0.0, which run in another job.

Hence my question : how can I pass the release URL from my release creation job to the job that will push artifact ?

And I copy it here

I would like to extract key value pair output from JSON formatted file using PHP and put into html table & database with exact key column. I tried code mentioned in Extract JSON ouput to get line by line key pair values using PHP but it doesn't work for multiple lines and gives wrong output from 2nd line onwards itself due to multiple lines from 2nd key.

As we discussed in that, filing separate question to avoid clutter the same question.
