Package shlex implements a simple lexer which splits input in to tokens using
shell-style rules for quoting and commenting.
The basic use case uses the default ASCII lexer to split a string into sub-strings:
shlex.Split("one \"two three\" four") -> []string{"one", "two three", "four"}
To process a stream of strings:
l := NewLexer(os.Stdin)
for ; token, err := l.Next(); err != nil {
// process token
}
To access the raw token stream (which includes tokens for comments):
t := NewTokenizer(os.Stdin)
for ; token, err := t.Next(); err != nil {
// process token
}
