Shebang support is broken

GoogleCodeExporter commented 9 years ago

What steps will reproduce the problem?
1. Prepare a Scheme script file:

#!/usr/local/bin/rose

(display "hello")

2. Try to parse this file with rose

What is the expected output? What do you see instead?

Expected: ( display "hello" )
Actual: an error is reported.

Please use labels and text to provide additional information.

This error is caused by the following code in rose/parser/impl/r5rs_grammar.ipp:

 34     shebang
 35         =   lexeme[confix("#!", eol)[char_]]
 36         ;

It should be +char_ rather than char_.

I made a mistake, +char_ cannot help, it should be +(char_ - eol).
