Public bug reported: We’re renaming the rotation operators from <<< (ROL) and >>> (ROR) to ^< (ROL) and ^> (ROR) to make space for >>> as another right-shift operator, to be able to map both SHR and SAR into shell, and for (as izabera requested) better consistency wrt. other languages.
Unfortunately, for the languages separating this operator, the mapping is as follows: • SHL << • SHR >>> • SAR >> For C, >> is SAR for signed types and SHR for unsigned types. In POSIX, arithmetics are always signed and use C semantics. Therefore, R53 will document >> is to be renamed into >>> as SHR, and R54 will do that and newly introduce >> as SAR operator. (This is consistent with the $KSH_VERSION bump already done.) ** Affects: mksh Importance: High Assignee: Thorsten Glaser (mirabilos) Status: Triaged ** Changed in: mksh Status: New => Triaged ** Changed in: mksh Importance: Undecided => High ** Changed in: mksh Assignee: (unassigned) => Thorsten Glaser (mirabilos) -- You received this bug notification because you are a member of mksh Mailing List, which is subscribed to mksh.
