9295 :: Compile time imports

  Hello I am working on a browser based Js library with Nim and I need to read some svg files and assign their data to some constants at compile time. The code to read the svg uses the os library which to the best of my knowledge does not compile to js. So is there any way I can import os only during compile time.

  This works for me:

  import std / os
  
  const path = static:
      "test" / "123.jpg"
  
  import jsconsole
  
  console.log path
  Run

  Thanks assigning the the value of the code to const helped. Here is the code just in case anybody else needs it.

  from tables import `[]=`, OrderedTable
  from os import `/`, splitPath, parentDir, walkDir, PathComponent
  from strutils import split, strip
  
  const SVGS* : OrderedTable[string, string] = block :
      
      var svgs : OrderedTable[string, string]
      let assets_dir = currentSourcePath().parentDir() / "assets"
      for file in walkDir(assets_dir):
          
          if file.kind != pcFile:
              
              continue
          
          let
              filename = file.path.splitPath().tail
              split_filename = filename.split('.')
          
          if split_filename[^1].strip() != "svg":
              
              continue
          
          svgs[split_filename[0]] = readFile(assets_dir / filename)
      
      svgs
  
  Run
