I'm a maintainer of some smaller open source projects -- you have to consider it from the project owner's point of view. To say they "shoot down ideas" is a negative way of saying it, but from their point of view they&#x

Yeah, I agree with that. I had a significant feature included in the Python stdlib (os.scandir and related changes) and after it was included in 3.5, the core developers have made significant improvements to it (added "with statement&q

This is of course generated code (output from the C to Go converter), so to "easily maintain" it, you'd edit the Tcl C source files and re-generate these. The generated Go code is committed to the repo so the person using the

Is "ported" the right term here? It know the repo's README says "CGo-free port", but this is the C version of TCL transpiled from C to Go (see the ~13MB .go files per platform in the "lib" directory). Whic

Yes, taking the address of a local variable is exactly what it's doing. But Go's compiler (and garbage collector) ensures it's safe to do that. The compiler will allocate on the stack where possible, and the heap where necess

What version of Go were you working with? As the post shows, things have improved a lot over the years.

Brian sent me a lovely (and surprisingly lengthy) reply. He noted that length() was already O(N), as onetrueawk just represents strings as NUL-terminated C strings and uses strlen() (though strlen is a lot faster than decoding UTF-8). Howev

by benhoyt 4y ago
Yes, that's right. With my simplistic UTF-8-based implementation it turned length() -- for example -- from O(1) to O(N), turning O(N) algorithms which use length() into O(N^2). See this issue: https://github.com/benhoyt

Are you looking at the "simple" or the "optimized" versions? For the optimized, yes, the Go one is very similar to the C. For the simple, idiomatic version, the Go version [1] is much simpler than the C one [2]: 40 very
