'Calculate cyclomatic complexity from file in different programming language via script

I am working on writing a script that outputs information about my written source code. So far, I am analysing the code with Python scripts that I have written. There is a Test.cs class which is used for this analysis.
Now I want to calculate the cyclomatic complexity from Test.cs.

Currently I am working on Visual Studio Code. I am aware that Visual Studio offers such a functionality and there are also packages that I can use for this.

However, I wanted to find out whether it is possible

  • a.) to write a Python script which can analyse my Test.cs class or
  • b.) to create a C# project to analyse the corresponding Test.cs class and if so, how can I pass the value for my script?

Because I would like to output and evaluate this value separately for the user.

Also I found this interesting documentation:

https://docs.microsoft.com/en-us/visualstudio/code-quality/how-to-generate-code-metrics-data?view=vs-2022#metricsexe

But here it is not clear to me how I could build and call up the Metrics.exe accordingly.

Or are there other approaches I could pursue?

I look forward to your feedback.

The easiest method is probably to call and parse the output of Metrics.exe.

If you don't provide /out, it will print to stdout, so you can capture it in Python.

I don't use Windows, so I can't test this, but something along the lines of this should work:

import subprocess
import xml.etree.ElementTree as ET

o = subprocess.run("Metrics.exe", "/project:ConsoleApp20.csproj", capture_output=True, check=True, text=True)
root = ET.fromstring(o.stdout)
print(root)

From there, just select the metrics you're looking for.

You need to stopPropagation for the event when element three is clicked so that it doesn't bubble up to the parent (box) element.

document.getElementById('box').addEventListener('click', () => 
  alert('triggered')
);

document.getElementById('box_child_three').addEventListener('click', e => 
  e.stopPropagation()
);
<div id="box">
  <div id="box_child_one">one</div>
  <div id="box_child_two">two</div>
  <div id="box_child_three">three</div>
</div>

Solution 3:[3]

<div id="box">
    <div id="box_child_one" trigger></div>
    <div id="box_child_two" trigger></div>
    <div id="box_child_three"></div>
</div>

<script>
document.querySelector('#box').onclick = function(e){
  if(e.target.hasAttribute('trigger')){
    alert('event fired')
  }
}
</script>

I'd go for this. As you are now no longer relying on an id to carry this out making it more re-usable
