8848 :: generating javascript from nim code evaluation at runtime

• Niminem (orginal) [2022-01-27T07:15:46+01:00] view original

  Is there a way we can use the javascript codegen at runtime? Specifically, for passing stringified Nim into a procedure that returns stringified javascript. I looked at the js folder inside the Compiler and found jsgen.nim. I believe this is the src but I have zero clue how any of it works lol

  You have to run the whole compiler on the JS backend. You can do this with either exec or calling the Nim compiler as a library somehow. It's probably not worth figuring out how to call the compiler as a library though, because you have to look at its own source code for how it calls itself and it's a pretty big dependency if you get it through nimble.

  That's totally fine having to run the compiler, I've done it with some projects (using nimscript at runtime). I figured that's how it probably has to happen!

  What I've been doing so far is using the commandline to execute nim code, targeting the JS backend. This produces a file though. Rather than writing to and reading from that file I'd like to have a string returned from a procedure. Or at least have the result via stdout so I can read it from there I guess lol
