Re: Nim Modbus library

[shashlick]

Couldn't resist - here's a modbus wrapper based on 
[v0.2.0](https://github.com/nimterop/nimterop/tree/v020) of nimterop still in 
test.

For dynamically linking to libmodbus.so: 
    
    
     nim c -d:modbusGit modbus.nim
    
    Run

For static linking: 
    
    
     nim c -d:modbusGit -d:modbusStatic modbus.nim
    
    Run
    
    
    import os, strutils
    
    import nimterop/[build, cimport]
    
    const
      baseDir = currentSourcePath.parentDir()/"build/libmodbus"
    
    static:
      cDebug()
    
    getHeader(
      "modbus.h",
      giturl = "https://github.com/stephane/libmodbus";,
      outdir = baseDir,
      conFlags = "--enable-static=yes --disable-tests"
    )
    
    cPlugin:
      import strutils
      
      proc onSymbol*(sym: var Symbol) {.exportc, dynlib.} =
        sym.name = sym.name.strip(chars = {'_'})
    
    cOverride:
      type
        modbus = object
    
    when not defined(modbusStatic):
      cImport(modbusPath, recurse = true, dynlib = "modbusLPath")
    else:
      cImport(modbusPath, recurse = true)
    
    
    Run
