Hi, Stéph and I are trying to revive Coral. There is a unit test that fails: self assert: (CLIParameterParser boolean) fail: #('falsely'). CLIParameterParser class>>boolean | trueToken falseToken | trueToken := (self caseInsensitiveKeywords: #('true' 'yes')) end ==> [:token | true]. falseToken := (self caseInsensitiveKeywords: #('false' 'no')) end ==> [:token | false]. ^ self new setParser: (PPElementParser on: trueToken / falseToken message: 'boolean expected'); name: 'bool' CLIParameterParser class>>caseInsensitiveKeywords: aCollection ^ (PPChoiceParser withAll: (aCollection collect: [ :each | each asParser caseInsensitive ])) token I don't know if this test used to pass but I guess it did. I think the problem is in the new work around "contexts". Can somebody please help? -- Damien Cassou http://damiencassou.seasidehosting.st "Success is the ability to go from one failure to another without losing enthusiasm." --Winston Churchill
