Class Tokenizer

java.lang.Object

org.apache.felix.gogo.runtime.Tokenizer

public class Tokenizer
extends java.lang.Object

Bash-like tokenizer. Single and double quotes are just like Bash - single quotes escape everything (including backslashes), newlines are allowed in quotes. backslash-newline indicates a line continuation and is removed. Variable expansion is just like Bash: $NAME or ${NAME[[:][-+=?WORD]}, except it can yield any Object. Variables expanded within double-quotes, or adjacent to a String are converted to String. Unlike bash, indirect variable expansion is supported using ${$NAME}. Only a single variable assignment is recognized, with '=' being the second token. (Bash allows name1=value1 name2=value2 ... command args) Comments can only start where white space is allowed: # or // starts a line comment, /* starts a block comment. The following common uses do NOT start comments: ls http://example.com#anchor ls $dir/*.java
