add support for other languages

Technically the core logic needs:

1. list of symbols (

   lensm/internal/disasm/file.go

   Line 3 in d977133

   // File represents an object file, a module or anything that contains functions.

   )
2. a way to disassemble and get line number for each instruction (https://github.com/loov/lensm/blob/main/internal/disasm/code.go#L1)

Rest of the code should work fine.

Yes please! C++ source isn't loading right now.

@mcourteaux can you provide a minimal repro, it'll be easier to test.

[mcourteaux]

Sure:

#include <cstdio>

int main(int argc, char** argv) {
  std::printf("hello\n");
  return 0;
}

Compile it:

g++ main.cpp -o repro

Start lensm (not even sure if this is the default way, I don't use use go):

go run loov.dev/lensm@main repro

Result:

You also need to include dwarf information in the binary -- i.e. g++ -gdwarf main.cpp -o repro. It might work on linux already, but I haven't tested.

For installing the tool go install loov.dev/lensm@main, it'll put it in $HOME/go/bin by default. But using go run is fine as well, except it might try to fetch the latest version every time.

Just tried your suggestion, and it still isn't working. Is there some verbose mode that could give you more information? Thanks for telling me about go install. 😄

@mcourteaux if it doesn't work, then my guess was just wrong :).
