Many times we need to process some data before using it in our Github workflows, but we don't find the appropriate action.
For that, I did some research on how we can use any programming language to process our data easily & use it on Github workflow
I found this example on Github Doc :
As you see we can save some output on GITHUB_OUTPUT & use it later in
GITHUB_OUTPUT. It's the path of a temporary file generated by the runner.
Now we will use some programming language (Dart for an example) to process some data & use it on our Github workflow
We will use an example for Bump Flutter app version using this Fastlane plugin based on PR's labels
Now this is the dart script :
We process input data by removing all labels except major, minor & patch, and split it by (,)
Then in line 16 we get environment variables & select GITHUB_OUTPUT in line 17 to get the path of the temporary file generated by the runner
After it, we open the file by Dart & write our output ({name}={value}) that we need in Github workflow
Now we will create our Github workflow & use the Dart script onto it
First, we need to use a setup for Dart lang action (line 18) (or any language used).
Then on line 21 we run the Dart script and pass PR labels as args & this script will return just the labels we need for the bump version (patch,minor, major) & in line 37 we use (env.parts) as the output of the script to use it as an input for the bump version by Fastlane plugin
Now when merging PR. The workflow will get labels & remove unused labels by Dart script & pass the output to Fastlane plugin to bump the version & push a new commit
You can use these steps on any programming language
