    [ https://issues.apache.org/jira/browse/CLI-147?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12601176#action_12601176 ] 

Emmanuel Bourg commented on CLI-147:
------------------------------------

I did a comparison of the 3 parsers with the various option formats I had in mind. Here are the results :

|| ||GNU||Posix||Basic||
||Flags\\(tar -xvf foo.tar)|(x)\\x is recognized|(/)|(x)|
||Long name with hyphens + space\\(--user ebourg)|(/)|(/)|(/)|
||Long name with hyphens + equal\\(--user=ebourg)|(x)\\ParseException|(/)|(x)\\ParseException|
||Short name with hyphen + space\\(-u ebourg)|(/)|(/)|(/)|
||Short name with hyphen + equal\\(-u=ebourg)|(x)\\value is '=ebourg'|(x)\\value is '=ebourg'|(x)\\ParseException|
||1 digit short name + value\\(-O1, -V3)|(/)|(/)|(x)\\ParseException|
||2+ digits short name + value\\(-Xmx512M)|(x)\\ParseException|(x)\\ParseException|(x)\\ParseException|
||Short name only\\(-v, -version)|(/)|(/)|(/)|
||Long name only\\(--help)|(/)|(/)|(/)|
||Property\\(-Dprop=value)|(/)\\2 values: prop, value|(/)\\2 values: prop, value|(x)\\ParseException|
