Convert Devel-Cover db to lcov data format

[henry2cox]

I would like to use some features of lcov to analyze perl components in some projects. lcov itself is one such project :-)

Specifically, I would like differential coverage as well as date binning (described in https://arxiv.org/abs/2008.07947 or https://ieeexplore.ieee.org/document/9438597) - as well as to include perl components a unified project coverage report, and to add perl code to the coverage criteria used by the corresponding jenkins job.

The easiest way I can think of to do that is to translate Devel-Cover data into lcov .info file format.

The lcov ".info" file format is pretty simple - and more-or-less described in the geninfo man page.

Brief perusal suggests that it is not spectacularly difficult to write a screen scraper to convert the Devel-Cover HTML report to lcov format, for line, branch, and subroutine types - but it would likely be easier to write the format directly. I wondered if somebody had already done either of those - and could point me to the code.

Thanks

Henry
