cmdline-java

A getopt/argparser implementation in java. Very similar to getopt.tcl

features in my cmdline-java:

1. generate usage/help info from option list.
2. support GNU style option and more flexible: -a --along --b -c carg -d=darg -ooptionalarg -- --notoption
3. not just support a short and a long option, you can define a List {h help Help ? 帮助}
4. hide attribute of option object， used to hide some option in usage/help info
5. forward option

test with Cmdline.main

git clone https://github.com/tcler/cmdline-java
cd cmdline-java
javac com/github/tcler/cmdline/*.java
#the default java path is . if CLASSPATH not set
java com.github.tcler.cmdline.Cmdline -h -H -f file --file file2 -e 's/abc/xyz/'  -r -n  -s=A -oa=b -S ''  -i -x xfile --wenj=file3 --www -aa -vvv -S DD -- -0 -y

# or: run jar file
