How do I get the c code of a nim program?

Question

I followed the docs and compiled with nim compileToC helloworld.nim but it just spit out an executable. How can I see the intermediate C representation?

2019 Update (Nim 0.19.2)

The default nimcache directory has changed from the current working directory to:

$HOME/.cache/nim/<project_name> for Linux and MacOS
$HOME/nimcache/<project_name> for Windows

See the relevant nim compiler documentation article for details.

nim -c -d:release c helloworld.nim just creates the C files in nimcache, without compiling and linking them. -d:release makes the code easier to read.

and `nimcache` location depends on OS, on my system the C files ended up under `~/.cache/nim/`, in a directory named after each nim source file, with suffix `_d` or `_r`, presumably for "debug" and "release". You can control this with `--nimcache:...` command line switch. – Hugues M. Sep 28 '18 at 11:33

Solved: When you compile a nim program a nimcache directory is automatically generated in the same directory that contains the c code.

Not for a while, it seems. Nothing is generated in the working directory in 0.19. – Noein Oct 19 '18 at 12:10
