[antlr-interest] CLI with ANTLR - best practice

[thierryj8]

Best practice for CLI in Lex&Yacc, O'Reilly:

".. In order to scan the command line rather than a file, we must
rewrite input() and unput()..." (p38), 

"...The input routine handles calls from the lexer to obtain
characters" (p41),

"...The unput() routine handles calls from the lexer to "push back"
characters into the input stream." (p41)

Input() treats the CLI end of line as the end of file. Is there an
equivalent in ANTLR?
