What Hacker News says
3 sourceshttps://github.com/google/pasta has you beat :p
In Abstract Syntax Tree for Patching Code and Assessing Code Quality> Refactors are rarely as simple as moving a few file names or symbols around, at least where I work. While we do have some automation to help (and not break existing consumers), it’s significantly more involved in an SOA architecture for tier1 services. These sorts of big refactors also generally come with data model changes, performance profiling etc. This tool seems fantastic for parts of that, but not all of it.
Yes, I'd refer to that as a migration, which absolutely is a lot of effort, but a tool like this isn't going to be particularly helpful with a migration precisely because the majority of the effort with such a migration will be like...doing all the data stuff and traffic stuff. Changing the code is a minimal part. A refactor is often not a thing that even registers at a smaller company, because its on the scale of a few files.
Read the rest
But "Large Scale Changes" are a thing when you end up having millions of lines of code (https://www.youtube.com/watch?v=TrC6ROeV4GI), and tools like this one are useful for those kinds of changes. But a single LSC won't get you promoted.
And rf is neat, but in a very go way, it's not particularly exciting if you're familiar with https://github.com/google/pasta or https://github.com/bazelbuild/buildtools/blob/master/buildoz... or clangmr or https://github.com/google/Refaster, or outside of google Semgrep and Bowler and others, since its essentially the same, but built in go for go.
> Just as a friendly aside, your tone seems strangely defensive (though this may just be my fault reading this tired at 3AM)
Not at all. I was however, pointing out that "this was really just a way to brag about where they work. Seems oddly common among people that work at that company." was certainly unnecessary, and perhaps unkind.
