Re: Possible to use identifier construction to call proc by name (string)?

[geohuz]

I tried to write the code (by following the manual):
    
    
    import macros
    import tables
    
    var nameToProc {.compileTime.} = newTable[string, proc(): string 
{.nimcall.}]()
    
    macro registerProc(p: untyped): untyped =
      result = newTree(nnkStmtList, p)
      
      echo repr(p[0])
      let procName = p[0]
      let procNameAsStr = $p[0]
      
      result.add quote do:
        nameToProc.add(`procNameAsStr`, `procName`)
    
    
    proc foo: string {.registerProc.} = "foo"
    proc bar: string {.registerProc.} = "bar"
    proc baz: string {.registerProc.} = "baz"
    
    
    doAssert nameToProc["foo"]() == "foo"
    
    Run

But I get the following error:
    
    
    Error: unhandled exception: key not found: foo [KeyError]
    
    
    Run
