After rework this exmaple [https://nim-lang.org/docs/tut2.html#building-your-first-macro-generating-source-code](https://nim-lang.org/docs/tut2.html#building-your-first-macro-generating-source-code) import macros, strutils var cfgFile = """title_ENh = Hubanize title_DKh = Hubanize title_ENc = Cx Manager title_DKc = Cx Manager help_ENh = Help help_DKh = Hjælp help_ENc = Help help_DKc = Hjælp""" let inputString = cfgFile macro readCfgAndBuildSource(cfgFilename: string): typed = let inputString = cfgFile var source = "" for line in inputString.splitLines: # Ignore empty lines if line.len < 1: continue var chunks = split(line, '=') if chunks.len != 2: error("Input needs '=' split values, got: " & line) source &= "const lng" & chunks[0].strip & "= \"" & chunks[1].strip & "\"\n" if source.len < 1: error("Input file empty!") result = parseStmt(source) readCfgAndBuildSource("languagefile.cfg") echo lnghelp_DKc
I hope it help you.
