The first AIX C compiler called itself a "transcompiler" in it's manual, so yes, they are.

Any digitalized version of it available online?

Not that I know of.

But you can see the term of the day, "translator", here[0][1], and it isn't much of a leap to see how that evolved into translator-compiler, and then shortened itself.

I get that we've lost this battle, and some people seem to think there's a useful distinction being made, but man, does the word 'transpile' grate on me.

There was a battle? Transpile is between human readable sources, and compiler is always into machine readable code. This is the only project that I've seen to (for some reason) not conform to that definition. I guess I don't see the point of contention.

YACC compiles human readable source to human readable source.

Is it YACT now?

They're both bytecodes though? I don't see how that is compilation.

Compiling is independent of source and target language, although it is mostly used to describe transformation from a higher-level human friendly language into a lower-level machine friendly language. Even so, the defined meaning of compiling is independent of the source and target languages. If you want to use the word "transpiling", you would have to define it in terms of compiling; transpiling is a special case of…

It's really just semantics, but Merriam Webster defines a compiler as "A computer program that translates an entire set of instructions written in a higher-level symbolic language (such as C) into machine language before the instructions can be executed"

Looks like simple mark-and-sweep, yes. https://github.com/konsoletyper/teavm/blob/d882fd1/core/src/...

So basically useless for browsers

Why do you think so?

A dictionary really isn't a great source for the exact definitions of technical words. Wikipedia does much better in this instance: https://en.wikipedia.org/wiki/Compiler

> A compiler is computer software that transforms computer code written in one programming language (the source language) into another programming language (the target language).

Later on it lists some classes of compilers that could be called by more specific names than just "compiler".

> I think WASM has the ability for us to finally cross the language boundaries without marrying ourselves to C/C++ ABI Uhhhhh. This sounds like a kind of silly thing to say, when you just described the jvm. Except for the part where there is a common stdlib.

> Except for the part where there is a common stdlib. Yeah, and it's huge and interconnected (just see how much they had to do to get a java.base module and how large that still is). And the JVM has lots of specifics around threading, GC, OOP, classes, security model, etc. And many of those specifics don't translate to the needed safe-by-default, minimal-by-default bytecode for the web and other targets. I could real…

Whoever said JVM should be for the web? The question was, why don't we have a way to cross language boundaries and the answer was: we do, the jvm.
