Nimfix - Tool to patch Nim code
Usage:
nimfix [options] projectflie.nim
Options:
--overwriteFiles:on|off overwrite the original nim files.
DEFAULT is ON!
--checkExtern:on|off style check also extern names
--styleCheck:none|confirm|auto performs style checking for identifiers
and suggests an alternative spelling. If
'auto', it automatically corrects the
spelling. If 'confirm' it asks the user.
In addition, all command line options of Nim are supported.
