Convert Markdown to HTML
I have lots of documents written in Markdown format and I was looking for a way to convert them to HTML.
The curious case of implicit return
My son works at a company where they analyze source code and report on potential data privacy violations. For this they need to parse source code in various programming languages. He mentioned that one day they might need to support Perl too. I thought about the difficulties in parsing Perl and one case came to my mind was the strange implicit return from a function that Perl has.
Then I also thought that Rust also has some strange ideas. BTW Do you know that I have a new web site called Rust Maven where I write about Rust? Now you know.
Anyway, back to Perl:
Selectively ignore warnings (turn them off with no warnings)
I recommend always turning warnings on from the beginning of each Perl file.
However sometime we might want to avoid some warnings. We can selectively turn off warnings inside lexical scopes, that is, till the end of the current pair of curly braces.
