I have a CLI program that uses the flag package and has one flag and takes a string as its only nonflag argument. The string can be a complex expression, but it is possible that the first character of the string is a minus sign. This parses correctly:
powerseries -nterms=10 "x ^ 10" But this does not: powerseries -nterms=10 "-x ^ 10" It yields the error "flag provided but not defined: -x ^ 10". Is there a workaround for this problem? -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
