In the index page of "Functions" or "Classes" HTML report, if I click a function or class, it will go to the start line of the function or class in the related source file html page, which is quite convenient.

# https://github.com/coveragepy/coveragepy/blob/7.13.0/coverage/html.py#L604
602 page_data.summaries.append(
603 IndexItem(
604 url=f"{ftr.html_filename}#t{region.start}",
605 file=escape(ftr.fr.relative_filename()),
606 description=(
607 f"<data value='{escape(sorting_name)}'>"
608 + escape(region.name)
609 + "</data>"
610 ),
611 nums=analysis.numbers,
612 )We want this (region.start) in the JSON report also, it can be very helpful.
Describe the solution you'd like
# cat test.py
1 # test.py
2 def add(a, b):
3 return a + b
4
5 print(add(2, 7))
We can add a field start_line in the "functions" part, like:
sample JSON report
"functions": {
"add": {
"start_line": 2, // <== HERE
"executed_lines": [
3
],
"summary": {
"covered_lines": 1,
"num_statements": 1,
"percent_covered": 100.0,
"percent_covered_display": "100",
"missing_lines": 0,
"excluded_lines": 0,
"percent_statements_covered": 100.0,
"percent_statements_covered_display": "100"
},
"missing_lines": [],
"excluded_lines": []
},
