It automatically compiles the lexer in optimized mode, writing to ``lextab`` in the same directory as the calling file. This function is thread-safe. The returned lexer is *not* thread-safe, but if it is used exclusively with a single parser returned by :func:`yacc` then it will be safe. It is only intended to work with lexers defined within the calling function, rather than at class or module scope. Parameters ---------- lextab : str Name for the file to write with the generated tables, if it does not already exist (without ``.py`` suffix). package : str Name of a test package which should be run with pytest to regenerate the output file. This is inserted into a comment in the generated file. reflags : int Passed to ``ply.lex``. r)rr__file__.pyT)optimizelextab outputdirreflagsN) astropy.extern.plyrrospathjoindirname_LOCKexistsrr)rrr r caller_fileZlextab_filenameZ lextab_existsZlexerrrrr>s    $ rc@s eZdZdZddZddZdS)rznWrap a parser produced by ``ply.yacc.yacc``.
