Re: how to call a function by name?

[mratsim]

Here are 2 ways
    
    
    ## Sol 1 - if you can get by with identifier input
    
    proc fun1() = echo "ok1"
    proc fun2() = echo "ok2"
    
    template callfun(fun: untyped) =
      fun()
    
    ## Sol 2 - if you really need string input
    ## This also unrolls the loop
    import macros
    
    const fns = [fun1, fun2]
    
    macro callfun2(fun: string, listfunc: typed): untyped =
      result = newStmtList()
      
      echo listfunc.symbol.getImpl.treerepr
      
      for function in listfunc.symbol.getImpl:
        let f_str = $function
        result.add quote do:
          if `f_str` == `fun`:
            `function`()
    
    when isMainModule:
      callfun(fun1)
      callfun2("fun2", fns)
