5388 :: Renaming functions

• mantielero (orginal) [2019-10-23T14:08:42+02:00] view original

  I have a piece of C code which uses macros in order to rename functions:

  #define fmiPaste(a,b)     a ## b
  #define fmiPasteB(a,b)    fmiPaste(a,b)
  #define fmiFullName(name) fmiPasteB(MODEL_IDENTIFIER, name)
  
  #define fmiGetModelTypesPlatform      fmiFullName(_fmiGetModelTypesPlatform)
  Run

  How can I do something similar in Nim?

  Regards

  Templates and identifier construction:

  https://nim-lang.org/docs/manual.html#templates-identifier-construction.

  Example 1: https://github.com/numforge/laser/blob/c7ddceb0/laser/primitives/reductions.nim#L17-L43 Example 2: https://github.com/mratsim/weave/blob/master/e04_channel_based_work_stealing/profile.nim#L27-L30 and usage: https://github.com/mratsim/weave/blob/master/e04_channel_based_work_stealing/profile.nim#L96-L108

  Thinking a bit further, for me it only matters the name exported to C. I was thinking if it would be possible to use instead the exportc pragma (https://nim-lang.org/docs/manual.html#foreign-function-interface-exportc-pragma ).

  In particular, how could I replace prefix with the content of a variable?

  proc p(s: string) {.exportc: "prefix$1".} =
    echo s
  Run
