Hi, I'm reaching out to report a bug with the -*-pretty-print* option in bash. Consider the following script:
*case esac in (esac) echo esac;; esac* When bash is run with *--pretty-print* on this script the result is: *case esac in esac) echo esac ;;esac* which is no longer valid syntax. This is interesting because running pretty print mode on this script: *case esac in (nonkeyword) echo esac;; esac* similarly results in *case esac in nonkeyword) echo esac ;;esac* which is valid syntax. So what's happening is that when the parser sees esac as what's supposed to be a pattern it interprets it as the case command ending and everything following is bad syntax. Personally, based on the Bash manual, I find it a little unclear whether *case esac in esac) echo esac ;;esac* is valid syntax or not. However, assuming that it is indeed invalid syntax the bug fix should be as simple as special casing *esac* as a *clause *in *print_case_clauses *in *print_cmd.c*. Best, Seth
