The Day I Fell in Love with Fuzzing

Re:The Day I Fell in Love with Fuzzing by ergothus on Monday January 28, 2019 @01:52PM (#19020022)

Javascript is my strongest, and I have enough Python to be comfortable - I had a lot of Perl back in the day but that knowledge is fairly rusty (though Parse::RecDescent was my first exposure to parsers). I did Java for a few years, but I refer to those as my Dark Times and wouldn't want to venture back there. (Experienced Perl dev doing Java is NOT a good time for either the dev or the code)

I can't argue about the broad applicability of compilers, but the main reason I've avoided such tutorials is that I'm looking for something I can get the basics of in hours/days rather than a weeks/months.

For the record neither is experienced Java dev doing Perl.

If you got to the point of having a tree, but found them clumsy to work with, the first thing I'd suggest is to play with an AST explorer. https://astexplorer.net/ is quite good.

Picture the task of what you want to do in your head. Maybe you're writing a linter, and you want to enforce a rule like "never use the 'var' keyword". Write some example code and poke around in the explorer.

Another thing to keep in mind is that once you have a tree, usually you also want to have some tree traversal utilities, so that you can walk over the tree and optionally transform it.
